Background: The effect of obliquity of tendon laceration on repair strength is not well studied. The overwhelming majority of biomechanical studies assess repair strength following a laceration that is perpendicular to the long axis of the tendon. The aim of this study was to investigate whether the angle of tendon laceration affects the core suture strength. Methods: In all, 110 fresh human cadaveric flexor tendons were cut at varying angles of 15°, 30°, 45°, and 60° and the control group at 90°. All tendons were repaired with 6-strand modified Tang technique. The repair strength was tested using a custom-made tensioning machine, and the initial static gap force and the ultimate breaking force were measured. Results: The mean gap force and 95% confidence interval (CI) for the 15°, 30°, 45°, 60°, and 90° groups were 15.2 N (11.4-19.0 N), 15.8 N (13.6-18.1 N), 15.6 N (13.1-18.4 N), 16.6 N (13.7-19.5 N), and 22.3 N (16.6-27.9 N), respectively. In the same respective order, the break force and 95% CI were 25.9 N (21.9-29.8 N), 26.5 N (23.2-29.7 N), 31.1 N (26.1-36.1 N), 35.6 N (28.2-43.1 N), and 51.8 N (62.5-41.0), respectively. The Fisher least significant difference demonstrated significant differences between the control group and all experimental groups for both gap force and break force. Conclusions: Obliquity of tendon laceration affects the core suture strength when compared with a transverse cut. Flexor tendons cut at 90° demonstrated a higher overall gap force and breaking strength that were statistically significant when compared with all obliquely cut groups. These findings should be considered when repairing and starting postoperative therapy for obliquely cut tendons. [ABSTRACT FROM AUTHOR]

Puffy Hand Syndrome is a complication of intravenous (IV) drug abuse that causes swelling and edema in the hands. It was first described in prisoners in New York in 1965 and can affect up to 16% of IV drug users. The syndrome is characterized by non-pitting or minimally pitting edema, affecting the dorsal surface of the fingers and hands, and can progress to permanent swelling. The exact cause is not fully understood, but it is believed to be due to the sclerosing of the superficial venous system and lymphatics from IV injections of irritants commonly found in street drugs. There are currently no known medical or surgical treatments to reverse the swelling, and management focuses on symptomatic relief through elevation and compression. [Extracted from the article]

This article discusses a case of a 23-year-old man who presented with a firework-related injury to his face. The firework became lodged in his left jaw, and the bomb squad was called to safely remove the explosive. The patient underwent surgery to repair the facial fractures and restore function and aesthetics. The article also provides information on the epidemiology of firework-related injuries, the important considerations for managing facial injuries, and the potential causes of early and long-term morbidity following facial reconstruction. The case highlights the complex management required for facial injuries caused by fireworks and emphasizes the need for multidisciplinary care. [Extracted from the article]

Background. In 2020, reduction mammoplasties and mastopexies comprised 34.2% of all breast surgeries performed by plastic surgeons. Various approaches for the skin incision of these procedures have been described. The vertical pattern has become an increasingly popular option due to its lower scar burden. However, it is prone to dog-ear formation along the caudal aspect of the incision. Herein, we describe 5 technical steps to eliminate the dog-ear in patients undergoing vertical mammoplasties. Methods. A retrospective chart review was performed on all patients who underwent vertical breast reduction and mastopexy between the years 2008 and 2020 performed by the senior author. The 5 steps employed in eliminating the dog-ear are delineated and depicted pictorially. Results. A total of 58 patients and 89 breasts were operated upon. A majority of 66.6% were Caucasian, 33.3% were African American, and 1 patient was of Hispanic descent. The mean age was 53.2 years (19-73 years), and average BMI was 31.5 kg/m² (21.3-42.7 kg/m²). The average resection weights for reduction and mastopexy patients were 479 grams (100-1500 grams) and 58.1 grams (18-100 grams), respectively. Mean follow-up was 10.5 months (1-35 months). Only one patient developed a dog-ear (1.7%) in bilateral breasts (2.2%); however, the patient did not request a revision. Our revision rate over 13 years remained at 0%. Conclusions. Utilizing these 5 technical steps reduces the risk of dog-ear deformity and thereby diminishes the overall need for revisional surgery in patients undergoing short scar vertical mammoplasties.

Background: Latissimus dorsi myocutaneous (LDM) pedicled flaps are a well-established method for breast reconstruction in women with inadequate soft tissue coverage following mastectomy for breast cancer. The robust nature of the latissimus blood supply can accommodate immediate implant placement to increase breast volume; however, a known risk factor with this technique is implant malposition. By utilizing an acellular dermal matrix (ADM) in subpectoral implant-based LDM reconstruction, it is hypothesized that patients will experience a lower incidence of implant malposition. This 13-year retrospective review aims to evaluate the effectiveness of breast reconstruction using this technique., Methods: A retrospective review was conducted to identify all patients who underwent breast reconstruction following mastectomy with a LDM flap, subpectoral implant, and an ADM from 2007 to 2020 by a single surgeon at a single institution. Demographic and clinical data were collected and analyzed., Results: A total of 40 patients (LDM flaps, N = 51) were identified. Mean participant age was 50.25 ± 9.67 years and mean body mass index (BMI) was 30.85 ± 6.15 kg/m 2 . Comorbidities included hypertension (40.0%), diabetes mellitus (17.5%), and current smoking (25.0%). Mean follow-up was 31.52 ± 29.51 months. The most common complication was seroma formation (9.8%). No patients experienced implant malposition or flap necrosis., Conclusions: The use of a LDM flap and an ADM in implant-based breast reconstruction are each well described in the literature. This 13-year series supports the efficacy of these techniques utilized in combination to provide an aesthetic result while mitigating implant malposition during breast reconstruction of oncologic patients., Competing Interests: Disclosures: This study received no means of outside funding.

Background: Breast reconstruction in the obese patient is often fraught with poor patient satisfaction due to inadequate volume restoration. The off-label hyperinflation of saline implants is a direct yet controversial solution to this problem, with limited studies in the literature. This study sought to determine the safety and efficacy of this technique for breast reconstruction., Methods: A retrospective chart review was performed to identify all patients with a body mass index (BMI) greater than or equal to 30 kg/m2 who underwent breast reconstruction between the years 2013 to 2020 with saline implants filled beyond the manufacturer's maximum recommended volume., Results: The 21 patients identified had an average age of 49 years. The mean BMI was 39.5 kg/m2. A total of 42 implants were placed; 34 were 800 mL, 4 were 750 mL, and 4 were 700 mL. The average overfill volume was 302 mL (138%). Mean follow-up was 65.0 months. Of these, 1 (4.8%) patient with a history of chest wall radiotherapy underwent reoperation for unilateral implant exposure 27 days after the index procedure, no patient sustained spontaneous leak or rupture, and 1 patient had unilateral deflation following emergent central line and pacemaker placement 2 years after the implant was placed for an unrelated cardiovascular event., Conclusions: Hyperinflation of saline implants beyond the maximum recommended volume may be considered for volume replacement in obese patients undergoing implant-based breast reconstruction. This practice is well tolerated, has a complication rate comparable to using implants filled to the recommended volume, and has the potential to restore lost breast volume in the obese patient post mastectomy., Competing Interests: Disclosures: This study received no means of outside funding.
