BACKGROUND: Triangular fibrocartilage complex (TFCC) injuries, especially Palmer type IB, pose surgical management challenges due to associated distal radial ulnar joint (DRUJ) instability. Traditional surgeries entail risks of complications. Arthroscopic repair presents advantages but lacks consensus on optimal techniques. To evaluate arthroscopic dual-bone tunnel repair in patients with Palmer type IB TFCC injuries of the wrist.
METHODS: In this retrospective case series, grip strength ratio, joint range of motion, pain visual analogue scale (VAS), modified Mayo wrist score, and Disabilities of the Arm, Shoulder, and Hand (DASH) scores were assessed before and 12 months after surgery.
RESULTS: The cohort consisted of 45 patients. At 12 months, the grip strength ratio improved from 0.71 ± 0.08 to 0.93 ± 0.05 (P < 0.001), and wrist joint rotation increased from 126.78 ± 13.28° to 145.76 ± 8.52° (P < 0.001). VAS (1.60 ± 0.58 vs. 6.33 ± 0.91, P < 0.001), DASH (12.96 ± 3.18 vs. 46.87 ± 6.62, P < 0.001), and modified Mayo wrist (88.11 ± 4.43 vs. 63.78 ± 7.99, P < 0.001) scores all improved after surgery. The overall complication rate was 4.44%.
CONCLUSIONS: Arthroscopic dual-bone tunnel repair appears to be an effective intervention for alleviating wrist pain, restoring stability, and enhancing joint function in patients with TFCC Palmer type IB injuries.

The quadriceps tendon, crucial for body movement, is among the body\'s strongest tendons. Factors like diabetes or hormone use can weaken it, making even minor trauma potentially causing rupture. Bilateral spontaneous quadriceps tendon rupture, where both tendons tear simultaneously, is rare. Prompt diagnosis and treatment are crucial. We present a case of a 44-year-old woman who experienced bilateral rupture after falling while doing chores. She had immediate pain and limited knee movement. Diagnosis via physical examination and CT/MRI scans confirmed the rupture. Surgical repair followed by rehabilitation led to significant pain reduction and improved function within two months. Overall, her postoperative outcome was satisfactory. This study underscores the importance of clear diagnosis, timely surgery, and thorough rehabilitation for optimal patient recovery from bilateral quadriceps tendon rupture.

UNASSIGNED: To determine the effectiveness and safety of different patch materials in the treatment of pediatric patients with congenital supravalvular aortic stenosis (SVAS).
UNASSIGNED: 218 consecutive SVAS patients (age < 14 years) who underwent surgery from Beijing Fuwai and Yunnan Fuwai hospital between 2002 and 2020 were included. Patients were divided into the pericardium patch group (133 (61.0%)), modified patch group (43 (19.7%)) and artificial patch group (42 (19.3%)). The primary safety endpoint was patch-related adverse complications (post-operation patch hemorrhage or aortic sinus aneurysm at 2-year follow-up). The primary effectiveness outcome was the re-operation or restenosis at 2-year follow-up. Multivariable cox regression was used to obtain the hazard ratio (HR).
UNASSIGNED: The median age at operation was 43.5 months (IQR 24.0-73.0). Only three patients had patch-related adverse complications, and no difference existed among the three groups (p = 0.763). After a median follow-up of 24.0 months (IQR 6.0-48.0), patients with a pericardium patch had a lower re-operation or restenosis rate compared with the other two groups (pericardium patch vs modified patch, HR = 0.30, 95% CI 0.12-0.77; pericardium patch vs artificial patch, HR = 0.33, 95% CI 0.13-0.82), even in the main subgroup and sensitivity analysis.
UNASSIGNED: In pediatric patients, the safety of autologous pericardium patch is acceptable, along with lower rates of middle-term re-operation or restenosis.

BACKGROUND: Brachial artery aneurysms are defined as dilations greater than 50% of the normal diameter, which are rare among all peripheral arterial aneurysms. While they are often present as pseudoaneurysms, true brachial artery aneurysms are also detected rarely. In this case report, the surgical repair method of true brachial artery aneurysms, which is a rare condition, is explained.
METHODS: Herein, we present a 61-year-old male patient with complaints of swelling and pain in the right arm antecubital region that had been progressing over 6 mo. Upon the diagnosis of a true brachial artery aneurysm associated with arteriovenous fistula, the aneurysm was surgically repaired with an autologous saphenous vein graft. The patient was discharged without any neurovascular complications postoperatively.
CONCLUSIONS: True brachial artery aneurysms are rare and there are not any recommendations for their management in the current literature. Even though the treatment of true aneurysms in this artery is primarily based on a surgical treatment, endovascular repair also might be an option.

UNASSIGNED: Rotator cuff (RC) tears cause fatty degeneration, aggravated by delayed treatment. Surgical repair alone cannot reverse fatty degeneration. It was aimed to test if local injections of satellite cell-derived myoblasts or satellite myoblasts (SM) from the deltoid region and mesenchymal stem cells (MSCs) from the subcutaneous abdominal fat pad would stimulate myogenesis and decrease adipogenesis in the rat model of fatty degenerated RC tear.
UNASSIGNED: A standardized RC tear surgery was performed on both shoulders of 24 Wistar albino rats at t = 0, and rats were followed for 8 weeks to create a chronic degeneration model. The animals were randomly divided into repair + SM and MSC (n = 12) or repair only (n = 12) groups. Transosseous repair with or without stem cell-based injection was performed on the right shoulder of all rats on week 8, with additional injections on weeks 9 and 10. The left shoulders were used as control. The animals were followed until week 14 for recovery.
UNASSIGNED: Histological and histomorphometric analyses were performed in week 14. The repair + SM and MSC group had a significantly greater supraspinatus muscle mass than the repair only and control groups. The adipose tissue ratio was significantly lower in the repair + SM and MSC groups versus the repair only and control groups.
UNASSIGNED: Histologically, the repair + SM and MSC group had improved muscle and tendon organization. In treating chronically degenerated RC tear in a rat model, surgical repair combined with injections of SM and MSC improved fatty degeneration, tendon healing and myogenesis.
UNASSIGNED: Level III.

A four-year-old spayed female Shiba Inu dog weighing 6.1 kg presented with ascites. Cor triatriatum dexter (CTD) without any other concurrent cardiovascular anomalies was diagnosed using echocardiography. The ostium of the abnormal membrane dividing the right atrium into two abnormal chambers was surgically excised under cardiopulmonary bypass. All clinical abnormalities were resolved after surgery. However, seven months later, ascites and CTD recurred. A balloon-expandable stent was placed at the site of recurrence, which improved caudal venous return to the right ventricle. After the second procedure, ascites were resolved, and the dog remained asymptomatic for 18 months without complications. There are previous reports of successful surgical resection of the CTD and of stenting in recurrent CTD following balloon dilation in dogs. However, to the authors\' knowledge, no previous reports have described recurrent CTD in dogs after surgical resection of the CTD. In this case, as with recurrent CTD following balloon dilation, stent placement at the site of the CTD can be a viable treatment option when the abnormal membrane recurs.

UNASSIGNED: Urethrocutaneous fistula (UCF) is one of the major complications of circumcision. The risk factors associated with UCF are not clear-cut but its repair remains a challenge for urological surgeons. The aim of this study was to highlight the epidemiological, and clinical features and outcomes obtained from the management of UCF in the context of a country with limited medical resources where ritual circumcision is widely practiced.
UNASSIGNED: From February 2010 to December 2022, 35 patients underwent surgical repair for post-circumcision UCF in two tertiary hospitals in Yaounde, Cameroon. Simple closure, Thiersch-Duplay-Snodgrass and Mathieu techniques were performed.
UNASSIGNED: The mean age of patients was 7.4 ± 4.1 years with a range of 2 to 21 years; the median age at circumcision was 24 months (12; 48). Most (95%) of circumcisions were performed by paramedical staff. The majority of patients (n = 26) consulted for a bifid stream, Three-quarters of fistulae were located at the corona. Small fistulae represented 74.28% (n = 26) of cases as opposed to large fistulae (25.71%). More than 70% of patients underwent a simple closure. The therapeutic results were satisfactory in 91.4% of cases (n = 32) after an average follow-up of 91.85 ± 51.92 months. There were no statistically significant differences between the patients with coronal fistula and patients with distal penile fistula concerning demographic, clinical and surgical characteristics.
UNASSIGNED: Urethrocutaneous fistula is a major and frequent complication of circumcision mostly practiced by non-qualified personnel on children aged 24 months. The usual presentation is micturition with a bifid stream occurring on average 3 months after circumcision. Coronal fistulas are the commoner location. Simple closure, Thiersch-Duplay-Snodgrass and Mathieu technique appear to be safe with the advantages of low recurrence rate. An accurate diagnosis with a timeframe respecting the principles of fistula surgery combined with regular follow-up is mandatory for good long-term results with a low recurrence rate. Further prospective studies on the factors affecting the formation of urethrocutaneous fistula should be performed to prevent this complication of circumcision.

Surgical repair of the diaphragm is essential for survival in congenital diaphragmatic hernia (CDH). There are many considerations surrounding the operation - why the operation matters, optimal timing of repair and its relation to extracorporeal life support (ECLS) use, minimally invasive versus open approaches, and strategies for reconstruction. Surgery is both affected by, and affects, the physiology of these infants and is an important factor in determining long-term outcomes. Here we discuss the evidence and provide insight surrounding this complex decision making, technical pearls, and outcomes in repair of CDH.

UNASSIGNED: Thoracic endovascular aortic repair (TEVAR) is a widely employed clinical procedure for treating various aortic pathologies. However, some patients require subsequent surgical interventions post-TEVAR, particularly due to life-threatening complications such as aortic dissection. This study aimed to evaluate the safety and prognosis associated with additional aortic surgeries following TEVAR.
UNASSIGNED: A retrospective analysis was conducted on 21 patients who underwent aortic surgery after TEVAR at Guangdong Provincial People\'s Hospital between September 2016 and August 2020. By compiling and reviewing perioperative data, we assessed surgical-related complications and survival rates.
UNASSIGNED: Among the 21 patients, 95.2% were male, with an average age of 53 years. Preoperative comorbidities included hypertension in 15 individuals, abdominal aortic aneurysm in one patient, and coronary heart disease in two patients. The primary complications of TEVAR were stent leakage and retrograde aortic dissection, with the latter being the predominant type in subsequent aortic surgeries. The mean duration of aortic clamping during surgery was 130.0 minutes, with a deep hypothermic circulatory arrest time of 8.5 minutes. Postoperatively, two patients suffered in-hospital mortality, one developed renal dysfunction, four required re-entry into the operating room for further treatment, and the average length of hospital stay was 20 days. Following discharge, 14.3% of patients experienced complications, with central nervous system symptoms being the most prevalent. Kaplan-Meier survival analysis indicated a 5-year survival rate of 85.7%.
UNASSIGNED: Aortic surgical intervention following TEVAR is a safe therapeutic approach that can improve patient prognosis. However, meticulous management of the perioperative period is crucial for reducing the risk of complications and improving survival rates. This study provides valuable insights into aortic surgery post-TEVAR, but large-scale research is needed to validate these findings.

OBJECTIVE: To investigate the risk factors and prognosis of spinal cord injury (SCI) after surgical procedure in type A aortic dissection (AAD).
METHODS: Between January 2013 and December 2021, a total of 1647 patients with AAD underwent surgical procedure. Postoperative SCI occurred in 58 patients, including 24 patients with paraplegia and 34 patients with paraparesis. Factors associated with SCI were identified through comparison between patients with and without SCI.
RESULTS: The mean age was 48.8 ± 10.8 years for patients with SCI and 50.1 ± 12.1 years for those without SCI (P = 0.43), with a comparable gender distribution. Median numbers of intercostal and lumbar arteries with involvement were significantly higher in the SCI group (both P < 0.001). The highest (P = 0.033) and lowest (P = 0.001) levels of intraoperative mean arterial pressure (MAP) were significantly lower in the SCI group. Multivariable analysis revealed the number of segmental arteries involved (odds ratio = 1.14, 95% CI 1.08-1.20, P = 0.000), and the duration of hypothermic circulatory arrest (HCA) (odds ratio  = 1.04, 95% CI 1.01-1.08, P = 0.042) was positively associated with the occurrence of SCI. Conversely, the lowest level of MAP was negatively associated with SCI (odds ratio = 0.98, 95% CI 0.96-0.99, P = 0.031). During the long-term follow-up, 14 patients with paraplegia needed a wheel chair, while only 1 patient with paraparesis needed one (P < 0.001).
CONCLUSIONS: The risk of postoperative SCI increases when AAD patients experience segmental arteries involved, longer HCA duration and decreased intraoperative MAP during operation.
