Intraoperative photographs and measurements were taken of the skin, SMAS and platysmal suture suspension with mastoid crevasse inset...

Myotendinous junction (MTJ) injuries are prevalent in clinical practice, yet the treatment approaches are limited to surgical suturing and conservative therapy, exhibiting a high recurrence rate. Current research on MTJ tissue engineering is scarce and lacks in vivo evaluation of repair efficacy. Here, we developed a three-dimensional-printed bioactive fiber-reinforced hydrogel containing mesenchymal stem cells (MSCs) and Klotho for structural and functional MTJ regeneration. In a rat MTJ defect model, the bioactive fiber-reinforced hydrogel promoted the structural restoration of muscle, tendon, and muscle-tendon interface and enhanced the functional recovery of injured MTJ...

BACKGROUND: Liposarcomas represent ~9.8-16% of soft tissue sarcomas, with the extremities and retroperitoneum being the primary sites of occurrence. While liposarcoma in the inguinal region is uncommon, few reported cases originate from the retroperitoneum and protrude into the scrotum through the inguinal canal. Here, we present a case of a retroperitoneal liposarcoma with prolapse from the left inguinal canal into the scrotum following hernia repair with a mesh plug. CASE PRESENTATION: A 55-year-old male patient underwent a CT scan for a suspected recurrent inguinal hernia, which revealed a sizeable adipose-dense tumor by the left kidney extruded through the left inguinal canal surrounding the scrotum...

BACKGROUND: The primary aim of this study was to assess the long-term patient reported outcomes of arthroscopic rotator cuff tear (ARCR) using a single anchor tension band (TB) technique for small and medium supraspinatus tears at minimum 5-years follow-up. METHODS: A retrospective cohort study of consecutive ARCRs of small and medium supraspinatus tears using a knotless single anchor TB technique with minimum 5-year follow-up was carried out. Outcomes of interest included: range of motion (ROM) on examination under anaesthesia (EUA), visual analogue scale (VAS), American Shoulder and Elbow Surgeons (ASES) scores, Oxford Shoulder Score (OSS) and Short-Form (SF-12)...

BACKGROUND: There are many surgical techniques when repairing pectoralis major tears. However, there is no clear consensus on which repair technique is biomechanically superior. Our purpose was to perform a systematic review and meta-regression to evaluate the most biomechanically superior pectoralis major repair technique. METHODS: We performed a systematic review and meta-regression of six human cadaveric biomechanical studies evaluating fixation techniques for pectoralis major repairs...

OBJECTIVE: Blunt cardiac rupture is a life-threatening injury that requires surgical repair by cardiovascular or trauma surgeons. We report a case of blunt cardiac rupture in a rural area in which emergency physicians performed emergency department thoracotomy and surgical repair to save the patient's life. PATIENT AND METHODS: This case involved an 18-year-old female who was injured in a traffic accident and underwent emergency thoracotomy and surgical repair. RESULTS: The patient's left thorax was deformed, and sonographic assessment revealed pericardial effusion...

Deep anterior lamellar keratoplasty (DALK) involves the selective replacement of diseased corneal stroma while preserving healthy unaffected endothelium. While DALK has failed to gain widespread popularity, improved visual and refractive outcomes of large-diameter grafts, which patients directly perceive following suture removal, may represent a compelling reason to shift toward DALK. Since the unaffected host endothelium is retained, DALK offers the opportunity to use large-diameter grafts, which reliably achieves maximum visual potential without an increased risk of immune-mediated stromal rejection...

BACKGROUND Bariatric surgery (BS) has a lower percentage of complications than other abdominal surgeries. Hemorrhage in one of the most common complications and can be life-threatening. Hereditary factor XI (FXI) deficiency is a coagulation disorder that can result in excessive bleeding requiring intervention to restore hemostasis. Risks over benefits in patients with morbid obesity with BS indication, as well as those with FXI deficiency, should be carefully evaluated. This article reports the case of an obese woman with FXI deficiency -undergoing SG...

PURPOSE: To investigate the application and effectiveness of tension-reducing suture in the repair of hypertrophic scars. METHODS: A retrospective analysis of clinical data was conducted on 82 patients with hypertrophic scars treated at the Department of Burns and Plastic Surgery of Nanjing Drum Tower Hospital from September 2021 to December 2022. Patients were operated with combination of heart-shaped tension-reducing suturing technique and looped, broad, and deep buried (LBD) suturing technique or conventional suture method...

Precise orchestration of cell fate determination underlies the success of scaffold-based skeletal regeneration. Despite extensive studies on mineralized parenchymal tissue rebuilding, regenerating and maintaining undifferentiated mesenchyme within calvarial bone remain very challenging with limited advances yet. Current knowledge has evidenced the indispensability of rebuilding suture mesenchymal stem cell niches to avoid severe brain or even systematic damage. But to date, the absence of promising therapeutic biomaterials/scaffolds remains...

BACKGROUND: An unexpectedly large number of patients experienced local recurrence with transanal total mesorectal excision in Norway. This appears to be associated with cancer cell spillage during surgery. OBJECTIVE: To investigate the surgical field cytology during transanal total mesorectal excision. DESIGN: This was a prospective cohort study. SETTINGS: This study was conducted at a single center between June and December 2020...

INTRODUCTION AND IMPORTANCE: Traumatic diaphragmatic ruptures following blast injury or penetrating trauma rarely present themselves with chronic symptoms warranting elective surgery. CASE PRESENTATION: We present the case of a 49-year-old man who survived a grenade explosion and experienced chronic chest pain. Considering the previous trauma, computed tomography imaging was performed and showed a left-sided traumatic diaphragmatic rupture ventral to the spleen, resulting in herniation of the transverse colon and omentum in the thoracic cavity...

Of the 27 million surgeries performed in the United States each year, a reported 2.6% result in a surgical site infection (SSI), and Staphylococci species are commonly the culprit. Alternative therapies, such as nitric oxide (NO)-releasing biomaterials, are being developed to address this issue. NO is a potent antimicrobial agent with several modes of action, including oxidative and nitrosative damage, disruption of bacterial membranes, and dispersion of biofilms. For targeted antibacterial effects, NO is delivered by exogenous donor molecules, like S -nitroso- N -acetylpenicillamine (SNAP)...

PURPOSE: The aim of this study was to assess how gender might affect the clinical outcome and survival of meniscal allograft transplantation (MAT). METHODS: A total of 358 patients (23.2% women, 76.8% men) were treated with fresh-frozen nonirradiated allografts implantated arthroscopically using a single- or double-tunnel technique without bone plugs and peripheral suture to the capsule with 'all-inside' stitches. RESULTS: Patients were evaluated at baseline and 2-year follow-up with the Lysholm score, visual analogue scale (VAS) pain, the Knee Osteoarthritis Outcome Score (KOOS) subscales and Tegner score...

BACKGROUND: Iatrogenic vascular injuries (IVIs) due to diagnostic and therapeutic interventions are known but rare or probably under-reported. We present our four-year findings on patients with IVIs after catheterization or surgery who underwent vascular surgical repairs in a resource-limited setting. METHODS: A retrospective case series study between Jun 2018 and Sep 2022 of 35 patients diagnosed with IVIs and treated surgically at our hospital was included. The data on IVIs including patient characteristics, causes and type of injury, treatment, and outcomes were collected and analyzed...

BACKGROUND: Elbow ulnar collateral ligament (UCL) repair with suture brace augmentation shows good time-zero biomechanical strength and a more rapid return to play compared with UCL reconstruction. However, there are concerns about overconstraint or stress shielding with nonabsorbable suture tape. Recently, a collagen-based bioinductive absorbable structural scaffold has been approved by the Food and Drug Administration for augmentation of soft tissue repair. PURPOSE/HYPOTHESIS: This study aimed to assess the initial biomechanical performance of UCL repair augmented with this scaffold...

BACKGROUND: Necrotising fasciitis (NF) is a life-threatening soft-tissue infection that rapidly destroys the epidermis, subcutaneous tissue, and fascia. Despite their low virulence, Lactobacillus spp. can cause NF, and because of its rare incidence, there is limited information about its molecular and clinicopathological characteristics. We report a rare case of NF in a patient with type 2 diabetes mellitus diagnosed on admission and severe obesity due to infection with two types of Lactobacillus spp...

BACKGROUND: Concomitant tricuspid valve (TV) repair is a safe and effective procedure to protect against late moderate or greater tricuspid regurgitation (TR) after left-sided valve surgery, but studies regarding its late outcomes and recurrent TR are limited. This study aimed to reveal the late outcomes and explore the predictors of mortality and recurrent TR among patients who underwent concomitant TV repair with left-sided valve surgery. METHODS AND RESULTS: This study included 645 patients (mean age, 69...

PURPOSE: Barbed sutures are tissue control devices that can reduce operating room time and costs. We analyzed the utility of barbed sutures in posterior spinal surgery in order to prove non-inferiority to conventional methods for wound closure. METHODS: A cohort of patients undergoing elective posterior spinal surgery in which barbed (prospective) versus conventional sutures (retrospective) were used was analyzed. The primary endpoint was the occurrence of wound healing complications or the need for surgical revision...
