Background: The transfer of latissimus dorsi (LD) and teres major (TM) have been described for restoration of external rotation (ER) and shoulder abduction in neonatal brachial plexus palsy (NBPP). The aim of this prospective randomised study is to compare the outcomes of LD versus TM transfer in the treatment of internal rotation contracture of the shoulder in children with NBPP. Methods: The study was conducted from February 2014 to January 2018 and included NBPP patients with internal rotation contracture of the shoulder. Patients were randomised to either LD (Group 1) or TM (Group 2) tendon transfer. Patients were followed up for at least 38 months and assessed for improvements in the arc of shoulder abduction and ER. Results: The study included 30 patients with 15 patients randomised to each group respectively. Group 1 (n = 15) included 4 boys and 11 girls with a mean age of 2 years and 8 months (range: 1.5–5) and a mean follow-up of 62 months (range: 38–68). Group 2 (n = 15) included 6 boys and 9 girls with a mean age of 2 years and 6 months (range: 1.5–4.8) and a mean follow-up of 58 months (range: 38–68). All patients showed improvement in shoulder abduction and active and passive ER. There were no differences in shoulder abduction (p = 0.467), active ER (p = 0.124) and passive ER (p = 0.756) between both groups. Conclusions: Both LD and TM tendon transfers improved shoulder function in NBPP patients with internal rotation contracture of the shoulder.

Introduction: The reconstruction of extensive scalp defects often requires free tissue transfer, offering single-stage and reliable reconstruction. The aim of this study is to evaluate the outcomes of free tissue transfer in scalp reconstruction. Patients and Methods: Thirteen patients were included in the study. Patient age, gender, smoking status, comorbidities, defect etiology, the specific type of flap used, the chosen recipient artery and vein, the need for revision, and flap success were reviewed. Results: The majority of the patients were male (76.9%). Defect reconstruction was performed using the latissimus dorsi musculocutaneous flap in 10 (71.4%) cases, which was followed by anterolateral thigh (ALT) and vertical rectus abdominis flaps. Two patients needed expansion of latissimus dorsi flaps. Superficial temporal vessels were used as recipient vessels in most patients. Three patients required anastomosis revision, all of which resulted in flap success. Conclusion: The high success rate observed in this study may be attributed to close monitoring of patients in the postoperative period and quick, early decision-making for revisions when necessary. The latissimus dorsi flap is the best option when large area coverage is needed, while the ALT flap is preferred when minimizing donor site morbidity is a priority. The vertical rectus abdominis myocutaneous flap offers the advantage of a long pedicle for anastomosis, though it comes with higher donor site morbidity. The superficial temporal artery and vein are reliable recipient vessels for scalp reconstruction. [ABSTRACT FROM AUTHOR]

Variant anatomy in the axillary region is of great clinical significance. It is one of the most frequently accessed regions for radical dissection surgery. During routine dissection of embalmed cadavers, we found a rare case of two accessory muscular slips emerging from the lateral border of latissimus dorsi (LD) and the inferolateral border of pectoralis major (PM), crossing the neurovascular structures in the axilla and merging distally together to the brachial fascia at the upper end of humerus below the bicipital groove. The accessory slip from LD is commonly referred to as the "axillary arch" in literature. We identified the accessory slip from the PM crossing over the axilla as pectoralis quartus. These aberrant slips can cause neurovascular compression in the axilla and can have clinical implications. Prior knowledge of the variant anatomy is the key to successful surgery in the axilla, thereby avoiding inadvertent injuries and post-operative complications. [ABSTRACT FROM AUTHOR]

Background: Conventional Latissimus Dorsi flap usually offers an insufficient amount of skin and volume for breast reconstruction. The Kiss LD flap associated by immediate fat transfer, emerges as a promising total autologous reconstructive option. This method can be offered to those patients who have comorbidities that pose a high risk for microvascular reconstruction or those who simply prefer a simpler and safer reconstructive option. Methods: A Retrospective cohort study was conducted at the National Cancer Institute of Mexico. This study evaluated the use of the combined approach with Kiss LD flap and immediate fat transfer for total autologous breast reconstruction between March 1st, 2023, and February 29th, 2024. The study included demographic variables, (age, gender, and socioeconomic level), clinical variables (cancer staging, body mass index, comorbidities, and reason for selecting the method) and surgical outcomes (timing of reconstruction, laterality of reconstruction, surgery duration, flap dimensions, flap volume, fat graft volume, postoperative complications and postoperative hospital stay days). Results: Fifteen patients with an average age of 42 years (range 31–55 years) undergone total autologous breast reconstruction with Kiss LD flap and immediate fat transfer. The timing of reconstruction was immediate in 80% of patients and delayed in the 20% remaining. The reconstruction was unilateral in 67% of patients and bilateral in 33%. The average surgery time was 145 min (range 117–198). The reasons for choosing this method were categorized in four different groups: patients' preference for a simpler and safer method (47%), comorbidities that pose a high risk for microvascular reconstruction (33%), salvage of a failed DIEP flap (13%), and not feasible DIEP reconstruction because a previous abdominoplasty (7%). Paddle A measured 20 × 9 cm and Paddle B measured 11 × 4.5 cm. The average volume of the flap and fat transfer was 280 and 120 cc, respectively. No major complications nor total flap loss were registered. Conclusions: The Kiss LD flap associated with immediate fat transfer emerges as an interesting option for total autologous breast reconstruction. This approach presents a safe alternative with an adequate volume in those patients who are not candidates for or do not desire microvascular reconstruction. Level of evidence: Level IV, retrospective cohort study. [ABSTRACT FROM AUTHOR]

Background: Massive irreparable rotator cuff tears (MIRCTs) remain a challenging treatment paradigm, particularly for nonelderly patients without pseudoparalysis or arthritis. Purpose: To use a network meta-analysis to analyze comparative studies of surgical treatment options for MIRCTs in patients <70 years of age for several patient-reported outcomes, range of motion (ROM), and acromiohumeral distance (AHD). Study Design: Network meta-analysis of comparative studies; Level of evidence, 3. Methods: A systematic review of the literature, using PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, of the MEDLINE, Embase, and Cochrane Library databases was conducted from 2017 to 2022. Inclusion criteria were (1) clinical comparative studies of MIRCTs (with several study-specific criteria); (2) ≥1 outcome of interest reported on, with standard deviations; (3) minimum 1-year follow-up; and (4) mean age of <70 years for both cohorts, without arthritis or pseudoparalysis. There were 8 treatment arms compared. Outcomes of interest were the American Shoulder and Elbow Surgeons (ASES) score, Constant-Murley score, visual analog scale for pain, AHD, and forward flexion and external rotation ROM. A frequentist approach to network meta-analysis with a random-effects model was performed using the netmeta package Version 0.9-6 in R. Results: A total of 23 studies met the inclusion criteria, with 1178 patients included in the network meta-analysis. There was a mean weighted age of 62.8 years, 568 (48.2%) men, with a mean follow-up of 28.9 months. There were no significant differences between groups in regard to sex (P =.732) or age (P =.469). For the ASES score, InSpace balloon arthroplasty (mean difference [MD], 12.34; 95% CI, 2.18 to 22.50; P =.017), arthroscopic bridging graft (aBG) (MD, 7.07; 95% CI, 0.28 to 13.85; P =.041), and long head of biceps augmented superior capsular reconstruction (BSCR) (MD, 5.16; 95% CI, 1.10 to 9.22; P =.013) resulted in the highest P-scores. For the Constant-Murley score, debridement (MD, 21.03; 95% CI, 8.98 to 33.08; P <.001) and aBG (MD, 6.97; 95% CI, 1.88 to 12.05; P =.007) resulted in the highest P-scores. For AHD, BSCR resulted in the highest P-score (MD, 1.46; 95% CI, 0.45 to 2.48; P =.005). For forward flexion ROM, debridement (MD, 45.77; 95% CI, 25.41 to 66.13; P <.001) resulted in the highest P-score, while RSA resulted in the lowest P-score (MD, –16.70; 95% CI, −31.20 to −2.20; P =.024). Conclusion: For patients <70 years with MIRCT without significant arthritis or pseudoparalysis, it appears that graft interposition repair techniques, superior capsular reconstruction using the long head of the biceps tendon, arthroscopic debridement, and balloon arthroplasty provide superiority in various outcome domains, while RSA provides the least benefit in forward flexion.

An overall complication rates for implant-based breast reconstruction (IBBR) have been reported from 29 to 46%, particularly in the setting of adjuvant radiotherapy. Although the majority of the literature describes autologous conversion in such scenario, a microsurgical flap is not always feasible. The aim of the paper is to assess surgical and patient-reported outcomes of breast reconstruction using a Latissimus Dorsi muscle Flap (LDMF), harvested without a back scar, in combination with a tissue expander for a two-staged reconstruction in the setting of a previously failed IBBR. All consecutive patients undergoing a two-stages LDMF IBBR between January 2016 and June 2020 were retrospectively identified. A minimal length vertical incision along the posterior axillary line was used for LD flap harvest. Demographic, clinical and surgical data were collected. Aesthetic outcome was evaluated with the Aesthetic Item Scale, and BREAST-Q was used to assess patients' reported outcomes. Twenty-one patients met the inclusion criteria. Mean age was 45.6 years, and the average follow-up was 41.2 months after tissue expander replacement with definitive implant. All patients completed the secondary reconstructive procedure, without major complications both at reconstructive and donor flap site. All women reported to be very satisfied with the final breast reconstruction. Second-attempt implant-based breast reconstruction for patients with a previously failed IBBR is challenging. A conversion from prosthetic to a mixed breast reconstruction with a "no-back scar" LD flap and tissue expander can be considered as a valuable strategy, especially when an abdominal-based autologous breast reconstruction is not feasible or refused by the patients.

Background: This is a rare case of the surgical treatment of a subacute presentation of a latissimus dorsi tendon rupture via a posterior single-incision approach. Indications: The patient had extensive conservative, nonoperative treatment that failed, and ultimately a surgical intervention was required to return to his activities of daily living. Technique Description: The patient is positioned in a lateral decubitus position. A 10-cm incision is created along the posterior axillary fold. Sharp and blunt dissection is utilized to carefully mobilize the chronic tendon rupture. The tendon is captured with 2 suture tapes utilizing a locking Krackow whipstitch. The tendon footprint is identified between the pectoralis major and teres major. The insertion point is prepared with a Cobb to debride the soft tissue and decorticate the bone bed to optimize healing. Two endobuttons are loaded with the suture tapes and then passed through unicortical holes drilled in the tendon bed. Care is taken to ensure the 90° external rotation of the tendon is achieved. A tendon-slide technique is used to reduce the tendon to the humerus. Afterward, a free needle is used to pass 1 limb of the suture through the tendon before tying an additional knot for added fixation. Results: The patient was able to resume his activities of daily living without pain at the 4-month mark. Conclusions: After the failure of extensive nonoperative management, surgical treatment of a subacute complete rupture of the latissimus dorsi tendon via a single, posterior incision is an effective method of returning a patient to their painless activities of daily living.

Background: This paper aims to conduct a systematic review of the current literature to evaluate the clinical outcomes of concurrent latissimus dorsi and teres major (LD/TM) tendon transfer in reverse shoulder arthroplasty (RSA), and to compare that to isolated RSA. Methods: A comprehensive search on PubMeb, Web of Science, Embase and CINAHL was performed from inception up to January 20, 2023, in accordance with the Preferred Reporting Items for Systematic reviews and Meta-Analyses. Cohort studies, case-control studies, randomized controlled trials and case series that were written in English, which involved patients who underwent RSA with LD/TM transfer were included. Quality of studies was appraised using the Cochrane Risk Of Bias In Nonrandomized Studies of Interventions tool. Systematic review of Constant-Murley Score (CMS) and range of movement (ROM) was conducted. Results: Eight studies with a total of 265 patients were included. The average mean follow-up time was 42.5 months, with a range of 6 months to 136 months. Of the studies that reported outcomes of RSA with LD/TM transfer, five reported the CMS, five reported external rotation (ER) ROM and six reported forward flexion ROM. Comparing postoperative to preoperative scores, there was an improvement above the minimal clinically important difference for CMS (mean difference (MD) range = 22.40 to 41.80), ER (MD range = 29° to 36°) and forward flexion (MD range = 50° to 75°). Three studies that compared postoperative ER between RSA with and without LD/TM reported no significant difference. Conclusion: RSA with LD/TM transfer has good clinical outcomes postoperatively, but there is insufficient comparative data to suggest that it is superior or inferior to an isolated RSA.

Case: A 58-year-old, very active man sustained bilateral isolated teres major (TM) tendon tears when his arms were forcefully elevated overhead while wakeboarding. Staged surgical repair was performed. A progressive rehabilitation protocol was followed, and he returned to high-level activities 7 months postoperatively. At 1-year follow-up, outcome measures for bilateral shoulders were DASH 0, SST 12, ASES 100, and EQ-5D 1.0. Conclusion: Despite literature supporting conservative treatment, this case demonstrates that operative treatment of acute, isolated TM tears can result in highly successful outcomes for motivated active patients.

Background and objective. The reconstruction of breast sarcomas or locally advanced breast cancer requires a stable and safe surgical technique. The V-Y latissimus dorsi myocutaneous flap allows immediate reconstruction of large defects with minimal morbidity and mortality, while also allowing for potential subsequent aesthetic or microsurgical reconstruction. We present our experience through a series of cases. Methods. A series of 14 reconstructed women is presented. The most frequently treated cancer was breast angiosarcoma (5 cases). Technical particularities of the surgical technique employed are described. Defects of 17.8 x 17.2 cm were reconstructed, with some exposing the lung and pericardium. Resuts. The flap survival rate was 100%. No major complications were encountered; the defects were reconstructed in a stable and durable manner. The average hospital stay was 3 days. There was no local recurrence with an average follow-up period of 36 months, and the patients exhibited high satisfaction rates. Conclusions. In our series, the use of this flap provides a definitive and immediate solution to the problem but leaves the door open for subsequent aesthetic reconstruction. According to our experience, the risk / benefit profile of the flap presented in this study makes it an option that should be considered. [ABSTRACT FROM AUTHOR]

Chest-wall sarcomas are treated with extensive resections and complex defect reconstruction to restore chest-wall integrity. It is a difficult surgical procedure that incorporates a multidisciplinary approach for the best outcome, preventing paradoxical chest movement issues and reducing complications. We aimed to describe our experience of chest-wall reconstruction using polypropylene mesh (Marlex® Mesh) combined with methyl-methacrylate and soft-tissue coverage with a latissimus dorsi flap following sarcoma resection. Among the 53 patients treated for primary chest-wall sarcomas at the European Institute of Oncology (IEO) in Milan, Italy, from 1998 to 2020, 14 cases underwent chest-wall resection and reconstruction using polypropylene mesh, methyl-methacrylate and the latissimus dorsi flap. Patients with locally advanced breast cancers, locally advanced lung cancers, squamous cell carcinomas, and other secondary chest-wall malignancies were excluded from the study, as were the patients with different types of chest-wall reconstruction. In this study, 14 patients (6 men and 8 women) with various primary chest-wall sarcomas were enrolled. On an average, 2 ribs (range: 1–5) were removed during the surgeries, and the chest-wall defects ranged from 20 to 150 cm2 with an average size of 73 cm2. The mean follow-up period for these patients was approximately 63.80 months The combination of Marlex® mesh filled with methyl-methacrylate and covered using latissimus dorsi myocutaneous flap provides safe, low-cost and effective single-stage chest-wall reconstruction after surgery for primary sarcomas.

Accessory thoracic muscles in humans are relatively common and it is important to draw awareness to their variable presentations and potential clinical implications owing to their close association with the axilla. Here we report four cases of accessory thoracic muscle variations identified in the ethnically diverse whole-body donation population in Northern California (4 out of 48 donors, 8.3%). Of these, combined presentations of thoracic accessory muscles were observed in two of the donors, one involving bilateral axillary arches and a pectoralis quartus on the left and the other a unilateral axillary arch on the left and bilateral pairs of pectoral fascicles. In the former, the proximal ends of the left axillary arch and pectoralis quartus joined to form a common aponeurosis which inserted onto the deep tendon of the pectoralis major; in the latter, the pectoral fascicles originated from the surface of the ribs and inserted into the deep surface of the pectoralis major muscle. In the other two donors, unilateral axillary arches were observed. Our observations illustrate that accessory thoracic muscles, in isolated as well as combined forms, are commonplace in the general population. We also describe the proposed embryonic origins of these accessory muscles, which may reflect their frequent occurrence, and potential clinical implications of these muscles, as discussed in literature.

Background The deep inferior epigastric perforator (DIEP) and latissimus dorsi (LD) flaps are two widely used autologous breast reconstructions. Despite studies on flap-volume changes, the time of the first measurement is not immediately after surgery. Therefore, this study aimed to investigate the change in volume over time from the immediate postoperative period using a three-dimensional (3D) scanner.

Dorsal seroma is a common complication of autologous latissimus dorsi flap (ALDF) in breast reconstruction, and has limited the use of this technique, despite its aesthetic success. It is important to find a right technique to limit the incidence of seroma formation after ALDF. The aim of this study was to evaluate the effectiveness and tolerance of a dorsal quilting technique called "running quilting" using barbed resorbable suture in seroma prevention. Three hundred patients who underwent ALDF breast reconstruction in the period between 2004 and 2014 were included in this study. The population was divided in 3 groups; without quilting, with simple quilting suture, and with running quilting using barbed suture. The incidence of small seromas (requiring 1 or 2 aspirations during routine postoperative visits without adding additional appointments to the follow-up routine) was not significantly decreased: it was 54% in the non-quilted group, 47% in group 2 Quilting, and 34% in group 3 running quilting. However, quilting reduced the duration of drainage, and the rate of late seromas (from 8% to 0%), and chronic sero-hematomas completely disappeared in our experience. Running quilting using barbed suture is highly effective in preventing late and refractory donor-site seromas. Its effectiveness is expected to increase the use of ALDF in breast reconstruction, which we consider currently as one of the best autologous reconstruction techniques. [ABSTRACT FROM AUTHOR]

This article presents the findings of a study on the impact of latissimus dorsi flap reconstruction on shoulder dysfunction and quality of life in breast cancer patients. The study compared patients who underwent the reconstruction to a control group and found that there was no significant difference in disability and quality of life between the two groups. However, the reconstruction group did experience higher levels of pain and lower muscle strength in certain shoulder movements. The study concludes that functional impairment should not be a determining factor for choosing the reconstruction surgery. [Extracted from the article]

Elderly patients with a massive irreparable rotator cuff tear suitable for reverse total shoulder arthroplasty (rTSA), combined with additional loss of active external rotation (ER), experience distress after rTSA alone due to the inability to perform daily tasks that require spatial control of the arm's position. We hypothesized that performing a combined transfer of Latissimus dorsi (LD) and Teres major (TM) along with rTSA in such patients could lead to improved outcomes after surgery, including those requiring active ER. This is a retrospective review of 17 patients with a massive irreparable rotator cuff tear and loss of active ER, managed with rTSA and combined LD and TM transfer using a novel circumferential suturing technique. Eleven patients were female, and 6 were male, with a mean age of 73.2 years (ranging from 60 to 82 years). The mean follow-up was 60.5 months. Preoperative and final follow-up clinical and radiological findings were assessed and compared for all patients. The mean forward flexion (FF) increased from 92° to 137° (P =.001). The mean abduction improved from 94° to 106° (P =.025). The mean ER improved from −14° to 8° (P <.001). The mean range of internal rotation decreased from 4.9 to 4.3 points (thoracolumbar junction to L2) (P =.065). The mean improvement of strength expressed as a percentage of the opposite side was significant for FF, abduction, and ER (P <.001). The mean visual analog scale score for pain improved from 5.5 to 1.7 point (P <.001). The mean University of California at Los Angeles shoulder score increased from 12.6 to 26.7 points (P <.001). The mean Constant Murley shoulder score improved from 40.6 to 75.7 (P <.001). The mean activities of daily living score, which requires active ER, increased from 4.5 to 22.3 points (P <.001). There was a reversal of loss of active ER in 15/17 (88.2%) patients. No perioperative complications related to the tendon transfer and fixation were observed. The combination of rTSA with LD and TM transfer leads to gains in FF and ER, improving clinical outcomes, including those requiring active ER. Circumferential suturing of LD and TM transfer avoids problems with suture anchors, interference screws, or bone tunnels. The posterodistal attachment site opposite to the original LD insertion is endorsed to mitigate the loss of internal rotation. [ABSTRACT FROM AUTHOR]

Introduction Implant-based breast reconstructions (IBBRs) increased last years despite the growing indications for radiotherapy in the treatment of breast cancer. As a result, complications and reconstructive failures associated to IBBR have increased. Autologous breast reconstruction (ABR) using fat-augmented latissimus dorsi (FALD) has become popular in recent years.

Background: Necrotizing fasciitis is a rare and potentially life-threatening soft tissue infection, even more so when associated with fungal causative agents. Onset has been identified in nosocomial settings following elective surgery, but not in esthetic surgery. Case presentation: We here present a case of necrotizing fasciitis related to Candida albicans infection which occurred in an immunocompetent patient who received a cosmetic breast augmentation mastopexy combined with a Brazilian Butt Lift using autologous fat grafting. The case was managed with aggressive wound exploration and debridement. Treatment was delayed by the diagnostic challenge and the difficulty in identifying the causative agent, but the patient fully healed and recovered once the C. albicans was isolated in culture tests and appropriate antimycotic treatment was implemented. Conclusion: Considerations should be made regarding the possibility of implementing an antimycotic option for first-line empirical treatment despite the rarity of fungal etiology because of the threat of diagnostic delay and worse outcome.

Introduction: the muscular response on the main muscles of the propulsive phase of the upper limb in the crawl swimming style has been evaluated by means of tensiomyography (TMG), which was carried out through three parameters: activation time (Td), contraction time (Tc) and maximum deformation (Dm).The aim of this study is to evaluate the hypothesis of changes produced between lactic resistance training with passive rest and lactic resistance training with active rest. Material and methods: experimental study with ninety swimmers in the crawl stroke, with a mean age of 20 years. The session with passive recovery and the session with active recovery presented results with significant changes after the development of each of them in the Tc in the three muscles analysed, being in the Pectoralis Major (PM), p = 0.001, in the Latissimus Dorsi (LD), p = 0.01 and in the Tríceps Brachii (TB), p = 0.047. Conclusion: According to the results it can be deduced that lactic resistance training with passive rest and with active rest do not influence the muscle response if we compare both trainings. Only one of the Tc values changes, while the latissimus dorsi muscle also shows changes in Td.

Latissimus dorsi may contribute to trunk movement and control because of its extensive attachments to the trunk. However, electromyography studies have shown highly variable activity levels during trunk tasks. To critically evaluate whether latissimus dorsi has a role in trunk movement and/or control. Studies assessing the activation of latissimus dorsi using electromyography during trunk movements and/or trunk stability tasks were sourced (May 2022). Risk of biases and quality of evidence was assessed. Activation levels were pooled and meta-analysed where possible. Thirty nine of 6125 studies identified in the search met the inclusion criteria. The meta-analyses showed high latissimus dorsi activity levels (60% maximal voluntary contraction [MVC]) during ipsilateral trunk rotation and low levels (<20% MVC) during contralateral trunk rotation, extension and stability tasks. Considerable variability of activity levels existed between studies when using high loads. Quality of evidence was very low to moderate. Although high activity levels were found during ipsilateral trunk rotation, there is very low confidence that these activity levels reflect the true levels. There is moderate confidence latissimus dorsi has a limited contribution to trunk control. The use of surface electrodes and non-validated normalisation processes were critical methodological issues that contributed to lower quality of evidence. [ABSTRACT FROM AUTHOR]

Introduction Implant-based breast reconstructions (IBBRs) increased last years despite the growing indications for radiotherapy in the treatment of breast cancer. As a result, complications and reconstructive failures associated to IBBR have increased. Autologous breast reconstruction (ABR) using fat-augmented latissimus dorsi (FALD) has become popular in recent years. Methods We aimed to evaluate conversion to ABR using latissimus dorsi and immediate fat grafting in 61 cases with IBBR failure. Results Immediate reconstruction was found significatively related with an increased number of surgeries resulting from IBBR complications (p < 0.001). Note that 41% of the cases presented a grade III/IV Baker and Palmer capsular contracture, 29% implant extrusion, and 21% implant infection. Mean survival of the first implant was 16.95 months. ABR process was completed in 47% of cases with a single surgery. Statistically significant differences were observed between this fact and previous IBBR failure due to infection (p = 0.03) or extrusion (p = 0.01). Mean volume of fat graft was 429.61 mL, mean length of the surgical procedure was 3.17 hours, and the average length of hospital stay after surgery was 2.67 days. Only 3.3% of the cases developed some major complication. None of the cases presented reconstructive failure. Conclusion FALD is a very safe total ABR technique, an important fact in patients with previous reconstructive failures. The large volume of fat that can be grafted in a single surgery allows the reconstruction of breast in a reasonable size. The reduced length of surgery and hospital stay make the FALD technique an option to consider when an autologous but efficient and safe reconstruction is desired. [ABSTRACT FROM AUTHOR]

Objective: The vascular anatomy of the proximal subscapular artery has been previously classified into 2 major types depending on the presence of a common subscapular trunk. The purpose of this study was to determine the utility, reliability, and cost of routine chest imaging to identify these anatomical variations. Methods: Data were collected retrospectively at a tertiary medical center for patients who were undergoing CT chest for various indications between October 2019 and October 2020. Two independent and blinded readers interpreted CT chest with contrast of 52 patients for a total 104 sides. Results: The proximal branching pattern of the subscapular system was identified to have a common trunk in 99 (95%) sides. The remaining five sides (5%) demonstrated two arterial pedicles; with one patient exhibiting the variant anatomy bilaterally. Conclusion: Preoperative CT chest with contrast can accurately identify anatomic variation of the subscapular vascular system. For complex reconstruction requiring a single anastomosis in the vessel depleted neck, preoperative imaging can assure selection of a type I vascular anatomy of the proximal subscapular system. Preoperative imaging with contrasted CT has value in assessing this anatomy when planning for chimeric flaps involving circumflex scapular and thoracodorsal arteries.

Abstract Background Chest wall sinus with infection is a refractory disease caused by a variety of susceptible factors, and the treatment is still challenging. For clinically complex cases, although there are various surgical methods to choose from, it is still very difficult to achieve clinical cure, especially for patients with older age and many underlying diseases. Complete resection of chest wall sinus and application of repair and reconstruction technology may bring hope to refractory cases. Case presentation Herein, we report a case of a 67 year-old woman who had undergone breast cancer surgery and a history of multiple cycles of radiotherapy and chemotherapy. One year ago, she had a fistula in the left chest wall with yellow purulent fluid. After admission to our hospital, chest computed tomography (CT) showed the formation of the left chest wall sinus, accompanied by high-density images of the left clavicle, part of the ribs and part of the sternu. According to the patient's symptoms, signs and imaging examination, we preliminarily diagnosed the patient as chest wall sinus with infection and chronic osteomyelitis. Therefore, in the first-stage operation, the patient underwent left chest wall sinus resection, left partial rib resection, left partial clavicular resection and left partial sternal resection, After surgery, the wound surface was changed with gauze dressing with sensitive antibiotic solution every day until the wound surface was clean and new granulation was formed. In the second-stage operation, the wound surface was appropriately expanded, and the pedicled latissimus dorsi myocutaneous flap was transferred to the chest wall defect. Finally, the skin paddle was sutured without tension to the normal skin around the chest, and two drainage tubes were placed. Anti-infection, anti-spasm, anti-coagulation and other treatments were given after operation, and the survival of myocutaneous flap, wound healing and sinus disappearance were observed. Conclusion The application of pedicled latissimus dorsi myocutaneous flap in the treatment of intractable chronic chest wall sinus is an effective method. It does not change the shape of the thorax. The clinical effect is satisfactory in the near and medium term, which is worthy of clinical promotion.

Background: To optimize patients' functional external rotation outcomes, reverse total shoulder arthroplasties (rTSAs) including a latissimus dorsi tendon transfer were undertaken with promising early results and no significant increase in complications in comparison to traditional rTSAs. This was especially utilized for patients with a pronounced combined loss of elevation and external rotation. The purpose of this study is to evaluate and synthesize the findings of all relevant publications assessing the outcomes of rTSAs with associated latissimus dorsi transfer. Methods: We thoroughly searched the literature within the PubMed database using a standardized methodology. For our inclusion criteria, we included any study regarding rTSAs that contained functional outcome scores for postoperative range of motion (such as elevation, external rotation, etc.) or postoperative outcomes such as complications (reoperation, infection, etc.) and patient satisfaction. For the extraction of data, we used pilot-tested Google Forms to record extracted data. These data were then converted to spreadsheets (Microsoft Excel [Microsoft, Redmond, WA, USA]). This was done on 2 separate scenarios by 2 authors to ensure accuracy. We used the modified Coleman Methodology Score to assess the methodological quality of the studies in our samples. Meta-analysis mathematics and statistical analysis were performed using Stata software 17 (StataCorp, College Station, TX, USA). Results: Our search returned a total of 12 studies containing data of 213 shoulders receiving RTSAs with a latissimus dorsi transfer. Functional outcomes were available for 160 shoulders. The mean preoperative elevation of the affected shoulder was 73.57 degrees, and the mean postoperative elevation was 141.80 degrees. For external rotation, the mean preoperative average was −6.71 degrees, and the mean postoperative average was 22.73 degrees. The absolute Constant score average was 31.56 preoperatively, while the postoperative value was 68.93. In our sample, 25 patients (11.73%) required a revision of the RTSA implant due to complications. Discussion: Combined loss of elevation and external rotation can be a severely debilitating condition for those with a glenohumeral pathology. Latissimus dorsi transfer for this condition has been proven to be an effective modality. The reoperation and complication rate appears to be sizable, and as such surgeons should consider this when considering this modality for their patients.

Key Clinical Message: A middle‐aged female veteran artistic gymnast sustained an avulsion injury of the latissimus dorsi and teres major. The case reveals possible pitfalls in the current classification system and illustrates how a nonoperative approach, in contrast to recommended guidelines, was adequate for an excellent clinical outcome.

Introduction: Latissimus dorsi and teres major (LDTM) tendon transfer has demonstrated better clinical outcomes compared to Latissimus dorsi (LD) transfer for irreparable anterosuperior cuff (subscapularis/supraspinatus) tears; however, the biomechanical effects of these procedures are unknown. Therefore, the objective of this study was to compare kinematics and internal rotation of LDTM transfer to LD transfer for anterosuperior cuff tear. Methods: Eight cadaveric shoulders were tested in four conditions; (1) intact, (2) anterosuperior rotator cuff tear, (3) LDTM transfer, and (4) LD transfer. Glenohumeral kinematics and internal rotation at 0°, 30°, and 60° of glenohumeral abduction in the scapular plane were measured. Muscle loading was applied based on physiological cross-sectional area ratios with three muscle loading conditions to simulate potentially increased tension due to the advanced insertion site of the transferred tendons. Results: The anterosuperior rotator cuff tear leads to a significant superior shift of the humeral head compared to intact at 0° and 30° abduction (p < 0.039). Both the LDTM (p < 0.047) and LD transfers (p < 0.032) significantly shifted the humeral head inferiorly compared to the tear condition.; however, the LDTM transfer shifted the head in the anteroinferior direction compared to the LD transfer at 60° abduction and 30° ER (p < 0.045). Both LDTM and LD transfer significantly increased internal resting rotation (p < 0.008) and maximum internal rotation (p < 0.008) compared to anterosuperior rotator cuff tear and intact at 30° and 60° abduction. LDTM transfer resulted in a significant internal resting rotation compared with the LD transfer at 30° abduction with double muscle loading (p = 0.02). At 0° abduction, the LDTM transfer (p < 0.027) significantly increased maximum internal rotation compared to anterosuperior rotator cuff tear and intact. Conclusion: Although both LDTM and LD tendon transfer improved the abnormal humeral head apex position and internal rotation compared with the tear condition, the LDTM transfer was biomechanically superior to the LD transfer in a cadaveric model.

Scalp defects necessitate diverse approaches for successful reconstruction, taking into account factors such as defect size, surrounding tissue, and recipient vessel quality. This case report presents a challenging scenario involving a temporal scalp defect where ipsilateral recipient vessels were unavailable. The defect was effectively reconstructed utilizing a transposition flap and a latissimus dorsi free flap, which was anastomosed to the contralateral recipient vessels. Our report underscores the successful reconstruction of a scalp defect in the absence of ipsilateral recipient vessels, emphasizing the importance of employing appropriate surgical interventions without necessitating vessel grafts.

Background: After latissimus dorsi transfer (LDT), an increase in scapulothoracic (ST) contribution in thoracohumeral (TH) elevation is observed when compared to the asymptomatic shoulder. It is not known which shoulder muscles contribute to this change in shoulder kinematics, and whether the timing of muscle recruitment has altered after LDT. The aim of the study was to identify which shoulder muscles and what timing of muscle recruitment are responsible for the increased ST contribution and shoulder elevation after LDT for a massive irreparable posterosuperior rotator cuff tear (MIRT). Methods: Thirteen patients with a preoperative pseudoparalysis and MIRT were recruited after LDT with a minimum follow-up of 1 year. Three-dimensional electromagnetic tracking was used to assess maximum active elevation of the shoulder (MAES) in both the LDT and the asymptomatic contralateral shoulder (ACS). Surface electromyography (EMG) tracked activation (% EMG max) and activation timing of the latissimus dorsi (LD), deltoid, teres major, trapezius (upper, middle and lower) and serratus anterior muscles were collected. MAES was studied in forward flexion, scapular abduction and abduction in the coronal plane. Results: In MAES, no difference in thoracohumeral motion was observed between the LDT and ACS, P = .300. However, the glenohumeral motion for MAES was significantly lower in LDT shoulders F(1,12) = 11.230, P = .006. The LD % EMG max did not differ between the LDT and ACS in MAES. A higher % EMG max was found for the deltoid F(1,12) = 17.241, P = .001, and upper trapezius F(1,10) = 13.612, P = .004 in the LDT shoulder during MAES. The middle trapezius only showed a higher significant difference in % EMG max for scapular abduction, P = .020 (LDT, 52.3 ± 19.4; ACS, 38.1 ± 19.7).The % EMG max of the lower trapezius, serratus anterior and teres major did not show any difference in all movement types between the LDT and ACS and no difference in timing of recruitment of all the shoulder muscles was observed. Conclusions: After LDT in patients with a MIRT and preoperative pseudoparalysis, the LD muscle did not alter its % EMG max during MAES when compared to the ACS. The cranial transfer of the LD tendon with its native %EMG max, together with the increased %EMG max of the deltoid, middle and upper trapezius muscles could be responsible for the increased ST contribution. The increased glenohumeral joint reaction force could in turn increase active elevation after LDT in a previous pseudoparalytic shoulder.

Background We suggested an easy and effective harvesting technique to avoid injury to tissues adjacent to the latissimus dorsi (LD). Methods Between 2007 and 2017, breast reconstruction was performed with an LD flap using the “bottom-up” technique. Medical records were retrospectively reviewed. Data on postoperative complications, results, and follow-up were obtained. Nine cadaveric dissections were performed to assess positional relationships between LD and adjacent muscles based on the ribs where relevant muscles and LD attach. Overall, 78 LD flaps were harvested without complications. Results Average age was 45.4 years. The mean operation time was 260 minutes. There were no abnormalities or injuries in the adjacent fascia and muscles during the flap harvest. Drains were removed at an average of 21.9 days postoperatively. In all cadavers, there was conjoined fascia between the thoracolumbar and LD fasciae. The average level of the merging point between the LD and external oblique muscle (EOM) was 8.9 to 11.1 ribs. The average level of the overlapping point between the LD and serratus posterior inferior (SPI) was 9.5 to 11.1 ribs. Conclusions There are three dangerous zones during LD flap harvesting. The first zone is where the conjoined fascia encompasses the LD and thoracolumbar fasciae. The second zone is where the LD merges with the EOM and the serratus anterior. The third zone is the lower part where the LD merges with the SPI and EOM. The “bottom-up” technique enables a more meticulous and atraumatic operation by beginner flap surgeons.

Background: Hyperselective neurectomy is a reliable treatment for spasticity. This research was designed to quantify the surgical parameters of hyperselective neurectomy of thoracodorsal nerve for shoulder spasticity through anatomical studies, as well as to retrospectively assess patients who underwent this procedure to provide an objective basis for clinical practice. Methods: On nine embalmed adult cadavers (18 shoulders), we dissected and observed the branching patterns of thoracodorsal nerve, counted the number of nerve branches, measured the distribution of branch origin point, and determined the length of the surgical incision. Next, we selected five patients who underwent this procedure for shoulder spasticity and retrospectively evaluated (ethic committee: 2022–37) their shoulder function with active/passive range of motion (AROM/PROM) and modified Ashworth scale (MAS). Results: The anatomical study revealed that the main trunk of thoracodorsal nerve sends out one to three medial branches, with the pattern of only one medial branch being the most common (61.1%); there were significant variations in the branch numbers and nerve distributions; the location of thoracodorsal nerve branches' entry points into the muscle varied from 27.2 to 67.8% of the length of the arm. Clinical follow-up data showed significant improvement in shoulder mobility in all patients. AROM of shoulder abduction increased by 39.4° and PROM increased by 64.2° (P < 0.05). AROM and PROM of shoulder flexion increased by 36.6° and 54.4°, respectively (P < 0.05). In addition, the MAS of shoulder abduction (1.8) and flexion (1.2) was both significantly reduced in all patients (P < 0.05). Conclusion: Hyperselective neurectomy of thoracodorsal nerve is effective and stable in the treatment of shoulder spasticity. Intraoperative attention is required to the numbers of the medial branch of thoracodorsal nerve. We recommend an incision in the mid-axillary line that extends from 25 to 70% of the arm length to fully expose each branch. [ABSTRACT FROM AUTHOR]

Background: Chest wall sinus with infection is a refractory disease caused by a variety of susceptible factors, and the treatment is still challenging. For clinically complex cases, although there are various surgical methods to choose from, it is still very difficult to achieve clinical cure, especially for patients with older age and many underlying diseases. Complete resection of chest wall sinus and application of repair and reconstruction technology may bring hope to refractory cases. Case presentation: Herein, we report a case of a 67 year-old woman who had undergone breast cancer surgery and a history of multiple cycles of radiotherapy and chemotherapy. One year ago, she had a fistula in the left chest wall with yellow purulent fluid. After admission to our hospital, chest computed tomography (CT) showed the formation of the left chest wall sinus, accompanied by high-density images of the left clavicle, part of the ribs and part of the sternu. According to the patient's symptoms, signs and imaging examination, we preliminarily diagnosed the patient as chest wall sinus with infection and chronic osteomyelitis. Therefore, in the first-stage operation, the patient underwent left chest wall sinus resection, left partial rib resection, left partial clavicular resection and left partial sternal resection, After surgery, the wound surface was changed with gauze dressing with sensitive antibiotic solution every day until the wound surface was clean and new granulation was formed. In the second-stage operation, the wound surface was appropriately expanded, and the pedicled latissimus dorsi myocutaneous flap was transferred to the chest wall defect. Finally, the skin paddle was sutured without tension to the normal skin around the chest, and two drainage tubes were placed. Anti-infection, anti-spasm, anti-coagulation and other treatments were given after operation, and the survival of myocutaneous flap, wound healing and sinus disappearance were observed. Conclusion: The application of pedicled latissimus dorsi myocutaneous flap in the treatment of intractable chronic chest wall sinus is an effective method. It does not change the shape of the thorax. The clinical effect is satisfactory in the near and medium term, which is worthy of clinical promotion. [ABSTRACT FROM AUTHOR]

Breast cancer-related axillary node dissection is the commonest cause of upper extremity lymphedema. The ability of lymphatics to regenerate spontaneously or reconnect with native lymphatics after free or pedicled flap reconstruction has been demonstrated on lymphoscintigraphy. Lymphatic anastomosis is not always needed in these flaps. In patients who underwent axillary clearance with risk factors for the development of lymphedema, we harvested a vascularized serratus anterior fascia flap during concurrent latissimus dorsi flap harvest (for breast or chest wall reconstruction). The vascularized fascia was wrapped around the axillary vessels to provide a conduit for lymphatic regeneration, protect the axillary vessels from radiotherapy, and reduce scarring and axillary cording. This procedure was performed on three patients with none of them experiencing upper limb lymphedema or cording.
