Learning curve of a novice foot and ankle surgeon in minimally invasive calcaneal fracture surgery via the sinus tarsi approach.

The sinus tarsi approach has gained popularity for treating calcaneal fractures; however, limited research exists on the learning curve among novice orthopedic surgeons. This study aimed to assess the learning curve of junior orthopedic surgeons who have recently completed their fellowship, focusing on surgical efficiency and clinical outcomes. From October 2022 to January 2024, 50 cases of calcaneal fractures (12 Sanders type 2, 23 type 3, and 15 type 4) were treated using the sinus tarsi approach at a single Level 1 trauma center.

Talar Allografts in Tibiotalocalcaneal Arthrodesis: A Salvage Approach for Complex Hindfoot Pathologies.

: Tibiotalocalcaneal (TTC) arthrodesis using talar allografts has emerged as a viable surgical option for managing complex hindfoot pathologies, including post-traumatic avascular necrosis (AVN), infection-related complications, and failed total ankle replacement (TAR). These conditions present significant therapeutic challenges due to extensive bone loss and joint instability. Previous reports have focused on TTC arthrodesis using talar allografts, highlighting its potential to provide enhanced structural support.

Effectiveness of a pelvic Binder-Only protocol for early stabilization in hemodynamically unstable pelvic ring injuries.

Background: Hemodynamically unstable pelvic ring injuries pose significant challenges in trauma care. Although external fixation is traditionally used for initial stabilization, pelvic binders have emerged as potential alternatives. Therefore, this study aimed to evaluate the feasibility and safety of maintaining pelvic binders alone as a temporary stabilization method in patients with hemodynamically unstable pelvic ring injuries.

From our study, bony union was achieved in all patients at an average of 3.

Management strategy for open pelvic fractures: A 11-year single-centre, retrospective observational study.

Introduction: Open pelvic fractures are commonly associated with life-threatening, uncontrollable haemorrhages. Although management methods for pelvic injury-associated haemorrhage have been established, the early mortality rate associated with open pelvic fractures remains high. This study aimed to identify predictors of mortality and effective treatment methods for open pelvic fractures.

Comparing postoperative pain in various pressure pneumoperitoneum of laparoscopic cholecystectomy: a double-blind randomized controlled study.

Purpose: This study aims to evaluate the effect of different pneumoperitoneum pressures on postoperative pain, especially by subcategorizing the pressures into 3 groups during laparoscopic cholecystectomy (LC).

Methods: We conducted a prospective randomized, double-blinded study of 150 patients with benign and uncomplicated gallbladder disease. They were categorized into 3 groups.

Mapping of acetabular posterior wall fractures using a three-dimensional virtual reconstruction software.

Introduction: The aim of this study was to analyze and describe the fracture patterns of the acetabular posterior wall based on quantitative measurements of the fracture characteristics.

Materials And Methods: Computed tomography images of 51 patients with acetabular posterior wall fractures from an initial cohort of 216 acetabular fractures were imported into a three-dimensional (3D) virtual software. The reconstructed 3D images were utilized to evaluate the following: (i) fracture line mapping on the inner articular and retro-acetabular surfaces, (ii) common zones of fracture and marginal impaction, and (iii) categorization by location and pattern of comminution.

Simple guidelines for evaluating intraoperative alignment after the reduction of intertrochanteric fractures.

The incidence of intertrochanteric femoral fractures has rapidly increased with the extended lifespan of the elderly population. Surgery enables early ambulation by achieving anatomic reduction and stable internal fixation. However, reduction usually involves postoperative evaluation.

Is the 8-mm robotic port safe? A case of trocar site hernia after robotic cholecystectomy using the da Vinci Xi system.

With the increase in the frequency of robotic surgery, complications have also increased, including trocar site hernias, which rarely occur at the 8-mm port site after robotic cholecystectomy using the da Vinci Xi system. A 37-year-old woman was diagnosed with cholecystitis on abdominal sonography. She underwent robotic cholecystectomy using a bikini-line incision.

Antibiotic coated hinged threaded rods in the treatment of infected nonunions and intramedullary long bone infections.

Introduction: Local delivery of high dose antibiotics in the form of antibiotic impregnated polymethyl methacrylate (PMMA) cement beads or coated rods is commonly used in the management of long bone infections. The downsides of antibiotic cement beads for intramedullary long bone infections are associated with difficulty in removal from the medullary canal, bead breakage, and lack of stability. Antibiotic cement-coated smooth flexible guide wires, rods and nails can have complications such as delamination or debonding of the cement.
