Autologous costal cartilage is commonly used as a graft material in plastic surgery. However, after autologous costal cartilage removal, the pain at the surgical site is particularly strong. We conducted this controlled clinical study to verify the efficacy of methylene blue (MB) in intercostal nerve block after autologous costal cartilage removal and to provide a reference for the application of MB in postoperative analgesia after autologous costal cartilage removal.In this study, 90 adolescent patients with congenital microtia who underwent autologous rib cartilage graft for auricular reconstruction were randomly allocated to one of three groups (Group A: intercostal nerve block was performed with 0.75% ropivacaine; Group B: intercostal nerve block was performed with 1% MB; and Group C: intercostal nerve block was performed with 1% MB and 0.75% ropivacaine mixture). Two trained researchers observed and recorded the pain status of the children at 6 hours (T1), 24 hours (T2), 48 hours (T3), and 72 hours (T4) after surgery, respectively. Numerical rating pain scale (NRS) was used for scoring. And adverse reactions such as nausea, vomiting, and skin itching were recorded.In this study, there was no statistical difference in age and gender of patients in Groups A, B, and C (P0.05). In terms of NRS comparison, 6 hours after operation (T1), Group BGroup AGroup C (P0.05); 24 hours after operation (T2), Group BGroup AGroup C (P0.05); 48 hours after operation (T3), Group BGroup AGroup C (P0.05); 72 hours after operation (T4), Group AGroup BGroup C (P0.05). There were no statistically significant differences in postoperative nausea, vomiting, and skin itching among the three groups (P0.05).The analgesic effect of IV self-controlled analgesia combined with ropivacaine is quick, but the maintenance time is short. The analgesic effect of IV self-controlled analgesia combined with MB is slow to onset but long to maintain. The analgesic effect of IV self-controlled analgesia combined with MB and ropivacaine mixture is quick and maintained for a long time. Therefore, in patients after removal of costal cartilage, we recommend the analgesic treatment method of IV self-controlled analgesia combined with MB and ropivacaine mixture.This journal requires that authors assign a level of evidence to each article.

The optimal approach to pain management after thoracic surgery remains poorly defined. The purpose of this study was to examine the association between intercostal nerve cryoanalgesia and postoperative opioid requirements after thoracic surgery.We conducted a single-center retrospective review of all patients who underwent unilateral thoracic surgery for pulmonary pathology from June 2017 to August 2019. Patients receiving intercostal nerve cryoanalgesia were compared with standard analgesia. The primary outcome was total oral morphine equivalent consumption during hospitalization, at discharge, and 90 d postoperatively. Secondary outcomes included pain scores and pulmonary function measured on postoperative days 1 and 3, at discharge, and postoperative complications. Planned subgroup analysis by opioid exposure and surgical approach was performed.The Wilcoxon rank-sum test demonstrated significantly less inpatient opioid use for cryoanalgesia patients (45 versus 305 mg, P 0.001), regardless of opioid history (naïve: 22.5 versus 209.8 mg, P 0.001; tolerant: 159.5 versus 1043 mg, P 0.001) and minimally invasive approach (opioid naïve: 26.2 versus 209.8 mg, P 0.001; tolerant: 158.5 versus 1059 mg, P 0.001). Opioid-naïve patients required fewer discharge opioids (50 versus 168 mg; P 0.05). Cryoanalgesia lowered daily pain scores (P 0.001) and showed a trend toward lower 90-d opioid prescriptions and higher pulmonary function scores. There was no difference in postoperative complications (P = 0.31).Our results suggest an association between intercostal nerve cryoanalgesia and reduced inpatient opioid requirements and pain in opioid-naïve and tolerant patients. Pulmonary function, 90-d opioid prescriptions, and adverse events were no different between groups. It may serve as a useful adjunct for opioid-sparing pain management in thoracic surgery.

Intercostal nerve cryoablation (cryoanalgesia) is increasingly used for pain control in minimally invasive repair of pectus excavatum (MIRPE) by Nuss procedure. Cryoanalgesia may lower core body temperature and increase the risk of postoperative infectious complications. We investigated cryoanalgesia effects on infectious complications following MIRPE.We performed a retrospective review of patients undergoing MIRPE at our institution. Patients treated via multimodal analgesia with cryoanalgesia (Cryo) were compared to patients treated via multimodal analgesia +/- elastomeric pain pumps (Non-cryo). Core body and intraoperative minimum/maximum temperatures were recorded. Primary outcomes were wound infection and pneumonia; secondary outcome was length of stay (LOS). Fisher's Exact and Mann-Whitney U tests compared proportions and medians respectively, p-value ≤ 0.05 being significant.80 patients were included, 35(43.7%) Cryo and 45(56.3%) Non-cryo. There were no significant differences in median [IQR] for age(15[13.3,16.0];p =0.86), number of bars inserted (2[1,2];p = 0.57), or operative time(123.5[98.3, 148.8]; p = 0.11) between the two groups. We found no significant differences in median [IQR] minimum temperature (35.4°C [35.0,35.8];p = 0.76), median change in intraoperative temperature (-0.13°C [-0.44,0.00];p = 0.94) or median recovery temperature (-1.10°C [-1.56,-0.65]; p = 0.59) between Cryo and Non-cryo. PACU temperature was significantly lower in the Cryo group, 36.4°C [36.2,36.6] p = 0.04. There were no postoperative wound infections in either group and no significant difference in incidence of postoperative pneumonia (8.57% versus 2.22%,p = 0.31) or median[IQR] for LOS (4[3,4];p = 0.57), between Cryo and Non-cryo patients.Although cryoanalgesia for MIRPE resulted in lower core body temperature, there appears to be no significant difference between Cryo and Non-Cryo patients for LOS or infectious complications.

Chronic postmastectomy pain affects up to 40 percent of patients and leads to diminished quality of life and increased risk of opioid dependence. The cause of this pain is incompletely understood; however, one hypothesis is that direct injury to cutaneous intercostal nerves at the time of mastectomy and/or reconstruction leads to chronic pain. As a result, proximal neurectomy of the involved sensory nerve(s) has been suggested to be effective for these patients. The purpose of this study was to determine whether chronic pain in postmastectomy patients can be diagnosed reliably in an office setting and pain reduced by intercostal sensory neurectomy. The authors performed a retrospective review of seven patients with a history of breast surgery and chronic pain who underwent intercostal neurectomy combined with muscle or dermal wrapping of the proximal end of the resected nerve. All patients were diagnosed by history and physical examination, and suspected nerves were further identified with local anesthetic nerve blocks. An average of 3.14 neurectomies were performed per patient (range, one to six). There was a significant reduction in visual analogue scale pain scores following surgery, from 9 preoperatively to 1 postoperatively (p = 0.02). Eighty-six percent of patients were pain-free or "considerably improved" at their latest follow-up appointment (average, 6.14 months). It is concluded that intercostal sensory nerve injury at the time of mastectomy and/or reconstruction can lead to chronic mastectomy pain, which can be easily diagnosed and effectively treated with intercostal neurectomy.Therapeutic, IV.

Background The Nuss procedure for pectus excavatum has historically been associated with significant postoperative pain, which has been the major factor contributing to hospital length of stay (LOS). Methods A single-institution, prospective study of 40 consecutive patients undergoing Nuss bar placement for pectus excavatum between November 2019 and January 2021 was conducted to assess the effectiveness of a multimodality pain management protocol. All patients received T3-T8 intercostal nerve cryoablation (INC), T3-T8 bupivacaine intercostal nerve blocks, Exparel at the skin incisions, and management with a perioperative analgesia regimen that minimized narcotic usage. The primary outcome was LOS. Secondary outcomes included opioid use, pain scores, and time to sensory recovery. Results 37/40 patients (92.5%) were discharged home on postoperative day (POD) 1, and 3/40 (7.5%) were discharged on POD 2 (mean LOS = 1.1 days). The median average postoperative pain score was 2/10. After eliminating IVPCA from our protocol, total oral morphine equivalent (OME) decreased by 73% (55.5 mg to 15 mg) with no change in pain scores or discharge timing. Conclusions INC combined with bupivacaine intercostal nerve blocks and a pre- and post-hospital analgesia protocol facilitated discharge one day after the Nuss procedure, achieved excellent pain control, and eliminated the need for intravenous opioids.

Intercostal Nerve Cryoablation (INC) has significantly improved pain control following the Nuss repair of pectus excavatum (PE). This study sought to evaluate patients undergoing the Nuss repair with INC compared to the Nuss repair with an ERAS protocol, INC, and intercostal nerve blocks (INB).In June 2020, a new protocol was implemented involving surgery, anesthesia, nursing, physical therapy, and child life with the goal of safe same day discharge for patients undergoing the Nuss repair. They were compared to a control group who underwent the Nuss repair with INC alone in 2017-2019. The primary outcome measure was hospital length of stay (LOS) in hours, secondary outcomes were number of patients discharged on postoperative day (POD) 0, and returns to the emergency department (ED), urgent care (UC), and operating room (OR).The characteristics between the groups were the same (Table 1). The mean LOS was 11.8 h in the INB group versus 58.2 h in the INC group, p 0.01. 10 of 15 patients in the INB group went home on POD 0 (average of 5.5 h postop), versus 0 patients in the INC only group, p 0.01. Five patients in the INB stayed overnight. Two patients stayed owing to anxiety, one owing to urinary retention, one owing to nausea, and one owing to drowsiness. None stayed for pain control. Four patients in the INC group returned to the ED for pain control, versus 0 in the INB group, and 1 patient in the INB returned to UC for constipation.The majority of patients undergoing the Nuss repair of PE with a multidisciplinary regimen of pre and postoperative nursing education, precise intraoperative anesthesia care, performance of direct vision INB and INC, as well as careful surgery can go home on the day of surgery without adverse outcomes or unanticipated returns to the hospital.Level II.

Background Slipping rib syndrome (SRS) is a painful condition of hypermobile, detached lower costal cartilages impinging the intercostal nerves. While surgical resection of the cartilaginous rib is reported as definitive treatment, recurrent symptoms are common. We describe the addition of vertical bioabsorbable rib plating to decrease recurrence. Methods An IRB-approved (#17-098), single institution, retrospective chart review was performed for patients who presented with SRS from 2009 to 2019 at a single institution. Descriptive statistics were used to compare patients with and without bioabsorbable vertical plating. Results A total of 85 patients (71.8% female, mean age 17.7 years) underwent evaluation for SRS. Of the 70 who underwent surgery solely for SRS, 29 (41%) underwent vertical rib plating at initial surgery while 41 (58.6%) did not. Recurrent symptoms developed in 7 (17.1%) unplated patients, while only 1 (3.4%) plated patient had recurrent SRS (which occurred after a motor vehicle crash) (p = 0.0116). Of the 8 with recurrent symptoms, 3 underwent vertical plating at a subsequent operation. Conclusion Rate of recurrent symptoms after cartilage resection alone for SRS was 17.1%. The addition of vertical rib plating with bioabsorbable plates decreased recurrent symptoms and improved outcomes. Level of evidence II.

Background: Chest wall surgeries are accompanied by severe postoperative pain. Inadequate relief of this pain may lead to both pulmonary complications as lung atelectasis and infection and chronic post thoracotomy pain syndrome. Regional analgesic modalities are important portion of the multimodal therapeutic approach suggested for the management of post thoracotomy pain. Objective: To evaluate serratus anterior plane block as a regional analgesia technique for post thoracotomy and thoracoscopy pain. Recent Findings: Serratus anterior plane block (SAPB), a regional analgesic modality developed by Blanco et al. in 2013, has shown good analgesic effect after thoracotomy and thoracoscopy in many case reports and clinical trials. In such block, a local anesthetic is injected in the fascial plane deep or superficial to the serratus anterior muscle leading to block of lateral cutaneous branches of the intercostal nerves. This provides a sensory block of T2–T9 dermatomes. Conclusion:Serratus anterior plane block as a fascial plane block can be a preferred regional analgesia technique for both post-operative pain management with procedures involving anterolateral chest wall as thoracotomy, thoracoscopy and breast surgery and in cases of multiple rib fractures. This is owing to its easy technique, effective pain relief and potentially better side effects profile compared to other regional modalities and systemic opioids.

Minimally invasive repair of pectus excavatum (Nuss procedure) is associated with significant pain, and efforts to control pain impact resource utilization. Bilateral thoracic intercostal nerve cryoablation has been proposed as a novel technique to improve post-operative pain control, though the impact on hospital cost is unknown.We conducted a retrospective study of patients undergoing a Nuss procedure from 2016 to 2019. Patients who received cryoablation were compared to those that received traditional pain control (patient-controlled analgesia or epidural). Outcome variables included postoperative opioid usage (milligram morphine equivalents, MME), length of stay (LOS), and hospital cost.Thirty-five of 73 patients studied (48%) received intercostal nerve cryoablation. LOS (1.0 vs 4.0 days, p 0.01) and total hospital cost ($21,924 versus $23,694, p = 0.04) were decreased in the cryoablation cohort, despite longer operative time (152 vs 74 min, p 0.01). Cryoablation was associated with decreased opioid usage (15.0 versus 148.6 MME, p 0.01) during the 24 h following surgery and this persisted over the entire postoperative period, including discharge opioid prescription (112.5 vs 300.0 MME, p 0.01).Bilateral intercostal nerve cryoablation is associated with decreased postoperative opioid usage and decreased resource utilization in pediatric patients undergoing a minimally invasive Nuss procedure for pectus excavatum.Retrospective comparative study, level III.

Although thoracoscopy has characteristics such as a small surgical incision and low stress response, post-surgical pain after a thoracoscopic operation is no less than that after a thoracotomy. Moreover, poor post-surgical pain management is likely to cause an increased incidence of postoperative pulmonary complications (PPCs) and chronic post-surgical pain. The serratus anterior plane block (SAPB) is a regional anesthesia method whereby local anesthetics (LAs) are injected into the serratus anterior space to block the lateral cutaneous branch of the intercostal nerve, long thoracic nerve, and dorsal thoracic nerve. The block range of the SAPB covers the incisions of video-assisted thoracoscopic surgery (VATS) and the site of the chest tube, which are often located in the antero-lateral chest wall. Therefore, the SAPB can achieve effective analgesia in VATS. For example, 0.125% to 0.25% levobupivacaine (20-25 ml) is widely used for thoracic surgery, which can achieve effective analgesia and avoid adverse reactions. Moreover, it has advantages compared with thoracic segmental epidural block (TEA) and thoracic paravertebral block (TPVB), such as simple operation, increased safety, fewer complications, and hemodynamic stability. In addition, adequate analgesia is helpful for pulmonary function recovery and reduces the incidence of PPCs. This article introduces the anatomical mechanism of the SAPB, diverse operation approaches, how to choose drugs and adjuvants, and the resulting impacted area range. It summarizes the advantages and disadvantages of the SAPB compared with other analgesic methods and posits that the SAPB is beneficial to the recovery of postoperative lung function, which provides more options for postoperative analgesia after VATS.

Post-mastectomy pain syndrome (PMPS) is a common and often debilitating condition. The syndrome is defined by chest wall pain unresponsive to standard pain medications and the presence of exquisite point tenderness along the inframammary fold at the site of the T4 and T5 cutaneous intercostal nerve branches as they exit from the chest wall. Pressure at the site triggers and reproduces the patient’s spontaneous or motion-evoked pain. The likely pathogenesis is neuroma formation after injury to the T4 and T5 intercostal nerves during breast surgery. We assessed the rate of long-term resolution of post-mastectomy pain after trigger point injections (2 mL of 1:1 mixture of 0.5% bupivacaine and 4 mg/mL dexamethasone) to relieve neuropathic pain in a prospective single-arm cohort study. Fifty-two women (aged 31–92) who underwent partial mastectomy with reduction mammoplasty or mastectomy with or without reconstruction, and who presented with PMPS were enrolled at the University of California San Francisco Breast Care Center from August 2010 through April 2018. The primary outcome was a long-term resolution of pain, defined as significant or complete relief of pain for greater than 3 months. A total of 91 trigger points were treated with mean follow-up 43.9 months with a 91.2% (83/91) success rate. Among those with a long-term resolution of pain, 60 trigger points (72.3%) required a single injection to achieve long-lasting relief. Perineural infiltration with bupivacaine and dexamethasone is a safe, simple, and effective treatment for PMPS presenting as trigger point pain along the inframammary fold.

Introduction Regional anesthesia techniques were recently introduced to provide analgesia for breast surgery. These techniques are rarely used as the primary anesthesia due to the complexity of breast innervation, with numerous structures that can potentially be disrupted during breast surgery. Case report A female patient in her sixties diagnosed with invasive ductal carcinoma on her left breast was scheduled for a simple mastectomy. After anesthetic evaluation, identification of high risk perioperative cardiovascular complications, it was proposed to perform the surgery only with regional anesthesia. A combination of pectoral nerve block (Pecs II), pecto-intercostal fascial block (PIFB) and supraclavicular nerve block ultrasound-guided were successfully performed. Conclusion This is the first case reporting a novel approach in a patient with severe cardiopulmonary disease who underwent breast surgery in a COVID-19 era.

Objectives The present study was performed to investigate the possible association between intercostal nerve block (INB) and postoperative glycemic control in patients with diabetes undergoing video-assisted thoracoscopic pulmonary resection. Design A retrospective study. Setting Single-center tertiary academic hospital. Participants Patients with diabetes, ages 18 to 79 years, who had undergone elective video-assisted thoracoscopic pulmonary resection (segmentectomy or lobectomy) from January 1, 2015, to December 31, 2018. Interventions Postoperative blood glucose levels and insulin dosage were extracted from the record. Measurements and Main Results Patients with diabetes who received INB before closure of surgical incisions were compared with those who did not receive INB. The primary outcome was the daily blood glucose (BG) level. Univariate analyses and multivariate regression analysis were performed to explore risk factors of hyperglycemia within 48 hours after the surgery. Baseline characteristics were comparable between the two groups. Patients who received INB had a lower maximum BG level and amplitude of glycemic excursion from zero-to-24 hours after surgery (p = 0.007 and p = 0.041, respectively) and lower maximum and minimum BG levels from 24-to-48 hours after surgery (p = 0.023 and p = 0.006, respectively). Meanwhile, the daily insulin dose increment during zero-to-24 hours and 24-to-48 hours after surgery decreased (p = 0.010 and p = 0.003, respectively), the white blood cell counts within 48 hours after surgery were lower (p = 0.021), and the length of postoperative stay decreased in the INB group (p = 0.044). Multivariate regression analysis further confirmed that INB was an independent protective factor of postoperative hyperglycemia (Nagelkerke R2 value 0.229; odds ratio 0.298; 95% confidence interval 0.099-0.901; p = 0.032). Conclusion INB, performed before closure of surgical incisions, was associated with improved glycemic control in patients with diabetes within 48 hours after video-assisted thoracoscopic pulmonary resection.

Thoracic sympathectomy to treat palmar hyperhidrosis (PH) has widely been performed. Many patients regret the surgery due to compensatory hyperhidrosis (CH), gustatory hyperhidrosis, arrhythmia, hypertension, gastrointestinal disturbances, and emotional distress. Robotic applications in microsurgery are very limited. We report the technique and long-term patient-reported outcomes of bilateral robot-assisted microsurgical sympathetic trunk reconstruction with a sural nerve graft in an interdisciplinary setting. A 59-year-old female suffered from severe adverse effects after endoscopic thoracic sympathectomy (ETS) for PH 25 years ago. She reported CH over the whole trunk, gustatory hyperhidrosis, excessive dry hands, and emotional distress. An interdisciplinary surgical team performed a bilateral sympathetic trunk reversal reconstruction with an interpositional sural nerve graft per side by a da Vinci® Robot. The nerve graft was microsurgically coapted using 9-0 sutures end-to-end to the sympathetic trunk stumps and side-to-end to the intercostal nerves T2-T4. At 24, 33 and 42 months, palmar dryness and emotional distress were strongly reduced. A highly specialized interdisciplinary setting may provide a precise, safe, and efficient treatment for ETS sequelae. A clinical study is initiated to validate this new therapy.

Background: Schwannoma is the most common neurogenic tumor of the posterior mediastinum. Though commonly become asymptomatic, back pain with intercostal neuralgia mimicking post herpetic neuralgia is rare presentation and infrequently found in the available literature. Case description: Here, we report a 22-year-old female without any history of trauma, surgery or infection presented with midback pain with radiation towards the right 10th intercostal space. Although clinical evaluation simulates the features of post herpetic neuralgia, she was mildly responsive to traditional conservative treatment. Later on, magnetic resonance imaging [MRI] was performed to rule out the neoplastic cause which ultimately revealed Schwannoma of the right 10th intercostal nerve. Patient symptomatically get well after complete removal of tumor. Beside this, we also briefly review the clinical presentation, neuroimaging features, different surgical options and outcome from the pertinent literature. Conclusion: This report emphasizes early radiological evaluation of dull aching resting pain to avoid unnecessary medications to prolong duration.

Introduction The transaxillary approach to resection of the first rib is one of several operative techniques for treating thoracic outlet syndrome. Unfortunately, moderate to severe postoperative pain is anticipated for patients undergoing this particular operation. While opioids can be used for analgesia, they have well described side effects, which has led investigators to search for clinically relevant alternative analgesic modalities. We hypothesized that a regional analgesic procedure, commonly called a pectoral nerve (PECS II) block, which anesthetizes the second through sixth intercostal nerves as well as the long thoracic nerve and the medial and lateral pectoral nerves, would improve postoperative analgesia for patients undergoing a transaxillary first rib resection. Methods We performed a retrospective study by reviewing the charts of all patients that had undergone a transaxillary first rib resection for thoracic outlet syndrome during the defined study period. Patients that received a PECS II block were compared to those that did not. The primary outcome was a comparison of numeric rating scale pain scores during the first 24-hours following the operation. Secondary outcomes included cumulative opioid consumption during the same time period. Results Pain scores during the first 24-hours following the operation were not statistically different between groups (Block Group: 3.9 [2.1-5.3] [median (IQR 25-75%)] vs. Non-block Group: 3.6 [2.4-4.1]; P = 0.40. In addition, opioid use through the first 24-hours after the operation was not significantly different (43.5 [22.0-81.0] [median morphine equivalents in mg's] vs. 42.0 [12.5-75.0]; P = 0.53). Conclusion An ultrasound-guided PECS II nerve block did not reduce postoperative pain scores or opioid consumption for patients undergoing a transaxillary first rib resection. However, a prospective, randomized, study with improved power would be beneficial to further explore the potential utility of a PECS II block for patients presenting for this surgical procedure.

Compensatory sweating (CS) is the most common and disabling complication of endoscopic thoracic sympathectomy and represents an unmet clinical challenge. Our surgical hypothesis is to generate a parallel pathway to the damaged part of the sympathetic nerve, similar to the Kuntz nerve, by reconstructing the 2 healthy intercostal nerves, thus treating CS. Here, we present a novel videothoracoscopic technique involving bilateral intercostal nerve reconstruction in patients with severe CS after endoscopic thoracic sympathectomy.

Background Spinal nerve block is difficult with minimally invasive cardiac surgery (MICS), because of the risk of serious bleeding complications due to full heparinization. Continuous extrapleural intercostal nerve block (CEINB) is a postoperative pain treatment for intercostal thoracotomy, with fewer complications. Here, we report a case in which imaging evaluation of CEINB with contrast medium was conducted to anatomically confirm the spread of local anesthetics after MICS. Case presentation A 65-year-old woman with severe mitral regurgitation underwent mitral valve plasty under general anesthesia via right-sided mini-thoracotomy. A CEINB catheter was placed before the incision was closed, without creating a conventional extrapleural pocket. We conducted an imaging evaluation with a contrast medium via the inserted catheter and confirmed sufficient spread around the intercostal nerve area. In addition, postoperative pain was well controlled by the nerve block. Conclusions Imaging evaluation of CEINB with contrast medium could increase analgesic quality and decrease complications post-MICS.

Intercostal nerve cryoablation (INCA) coupled with surgical stabilization of rib fractures (SSRF) has been shown to reduce post-operative pain scores but at what monetary cost. We hypothesize that in-hospital outcomes improve with the addition of INCA to SSRF and potential increased hospital charges are justified by patient benefits.Multi-institutional, retrospective review of patients undergoing SSRF with and without INCA over an 8-year period. Institutions involved were Level II or higher trauma centers. Basic demographics were obtained. Patients were included if SSRF was performed during the index hospitalization. Primary outcomes included total hospital length of stay (HLOS) and HLOS after SSRF, total hospital charges (HC), HC the day of surgery and HC after surgery. Secondary outcome included total narcotic consumption in morphine milliequivalents (MME) after SSRF. Mann-Whitney U test was used for analysis. Statistical significance p 0.05.136 patients analyzed; 92 underwent SSRF only and 44 underwent SSRF with INCA. Demographics were similar between groups. Number of ribs stabilized was comparable; 4.78 ± 1.64 SSRF only and 4.73 ± 1.66 SSRF with INCA (p = 0.463). Median ISS [16 (IQR 11.5-16) SSRF only and 14 (IQR 9-18.75) SSRF with INCA (p = 0.463)] was not statistically different. The INCA group showed a decrease in the median total HLOS, 9 versus 10 days (U = 1517.5, p = 0.026) and HLOS after SSRF, 4 versus 6 days (U = 1217.5, p 0.001). HC the day of surgery were higher for the INCA group, $93,932 versus $71,143 (U = 1106, p 0.001). However, total HC were similar between groups and total HC after SSRF was significantly less for the INCA group, $10,556 versus $20,269 (U = 1327, p = 0.001). Total median narcotic use after SSRF was significantly less for the INCA group, 88.6 vs 113.7 MME (U = 1544.5, p = 0.026).SSRF with INCA is safe and does not increase overall HC with the added benefit of decreased HLOS post-operatively and decreased narcotic consumption.

Slipping rib syndrome (SRS) is an uncommon condition, typically affecting young adults and adolescents. The syndrome is mainly characterized by chronic, restrictive pain, caused by the impingement of the loose false rib tips to the adjacent intercostal nerves. The most commonly involved ribs are the 9th, 10th, and 11th ribs. There are several reports and case series reporting the efficacy of surgical interventions for the treatment of SRS. Costal cartilage excision, rib resection, and rib stabilization-plating procedure are successful surgical approaches for the management of slipping rib syndrome.

Rib fractures are the most common injuries in blunt chest trauma. Rib fractures can cause a lung injury or may occur in the form of an isolated rib fracture. Isolated rib fractures that are broken in single point are usually followed at home with analgesic treatment. In our study, we aimed to investigate the effect of intercostal nerve blockage on pain, quality of life, return to work, and grip strength in patients with isolated single point rib fracture that did not cause lung damage. Between March 2020 and August 2020, a total of 61 patients with the diagnosis of isolated rib fractures were included and divided into two groups. Group 1 (n=29) received one session of intercostal nerve blockage (0.5% bupivacaine 3mL and 5 μg epinephrine) and acetaminophen 500 mg b.i.d. +celecoxib 100 mg b.i.d., while group 2 (n=32) received acetaminophen 500 mg b.i.d. +celecoxib 100 mg b.i.d. Pain severity was evaluated using the Visual Analog Scale quality of life using the Short Form-36, and grip strength using a hand dynamometer at baseline, 1 week, and 1 month. On the second day of evaluation, the patients with Visual Analog Scale score of

Targeted muscle reinnervation enables native muscles to send electromyographic signals to myoelectric receptors, which drive movements in a prosthesis. This system requires voluntary contracture of muscles for sequential control of powered prosthetic joints. This report describes a surgical solution for cases where the chest wall is depleted of muscle targets. A 13-year-old boy with left forequarter amputation and pectoralis major resection as a result of extended necrotizing facilities 8 years prior received a neurotized free Vertical Rectus Abdominus Mycocutaneous (VRAM) flap (28 × 10 cm) designed to produce myoelectric signals, reduce pain, and provide stability for prosthetic fitting. Five intercostal nerves from the VRAM were coapted to portions of the brachial plexus to create a myoelectric interface for targeted muscle reinnervation. The postoperative course was uneventful. At 39 months of follow-up, the patient gained control of the transferred VRAM and was able to operate a custom-fitted myoelectric prosthesis together with contraction of the ipsilateral infraspinatus muscle. The neurotized VRAM transfer created a neural interface in an area with depleted neuromuscular targets while decreasing pain and adding tissue bulk for proper prosthesis fitting. Such a surgical strategy may have applications in other areas of the body.
