Arteriovenous fistula and pseudoaneurysm in a pediatric patient with persistent postoperative hemarthrosis: A rare complication following arthroscopic repair of a bucket handle medial meniscal tear.

This case report highlights a rare complication of arthroscopic meniscal tear which is an arteriovenous fistula and pseudoaneurysm of the superior medial geniculate artery. A 14-year-old male patient presented with persistent hemarthrosis following arthroscopic repair of a bucket handle medial meniscal tear. The patient was investigated due to suspicion of vascular damage.

Biomechanical comparison of distal femoral fracture fixation: Polyaxial vs. uniaxial locking screws with different blocking screw configurations in retrograde femoral nailing.

Introduction: Clinical studies have indicated reduced reliance on blocking screws with the introduction of polyaxial locking nails, yet the biomechanical superiority of polyaxial locking over blocking screws remains unverified, specifically for distal dia-metaphyseal femur fractures.

Hypothesis: We hypothesized that the combination of multiaxial locking using three screws and parallel locking reinforced by two blocking screws would result in superior outcomes compared to utilizing only parallel locking with two screws and one blocking screw.

Materials And Methods: Third-generation custom-made femur models representing AO/OTA 32 A1.

Ultrasonographic comparison of bilateral patellar tendon dimensions in patients treated via intramedullary tibial nailing using a transpatellar approach.

Objective: One of the most common complications following intramedullary nailing of a tibial shaft fracture is anterior knee pain. The etiology of pain remains unclear. Patellar tendon entry point is the most suspected reason for anterior knee pain.

Effect of Repeated Sterilization by Different Methods on Strength of Carbon Fiber Rods Used in External Fixator Systems.

Objectives: We aimed to study the effects of repeated sterilization, using different methods, on the carbon fiber rods of external fixator systems.

Methods: We used a randomized set of 44 unused, unsterilized, and identical carbon fiber rods (11 × 200 mm), randomly assigned to 2 groups: unsterilized (4 rods) and sterilized (40 rods). The sterilized rods were divided into 2 groups, those sterilized in an autoclave and those sterilized using hydrogen peroxide.

Surgical treatment of displaced intraarticular calcaneus fractures using anatomical lateral frame plate.

Background: The present study evaluated the results obtained from the anatomical lateral frame plate treatment of displaced intraarticular calcaneus fractures.

Methods: Overall, 14 displaced intraarticular fractures of 13 patients (3 females, 10 males; Mean age, 37.5 years) were included in the present study.

Arthroscopic Technique for Treatment of Schatzker Type III Tibia Plateau Fractures Without Fluoroscopy.

Accurate reduction and maintenance of the stability with correct implant positioning is critical for surgical treatment of tibial plateau fractures. Our technique includes an arthroscopic reduction and fixation of Schatzker type III tibial plateau fractures with a bulls-eye screw placement without fluoroscopy control. With the arthroscopic guidance, an anterior cruciate ligament drill guide is placed and a K-wire sent to the midpoint of the depressed fragment through the guide at a 40° angle to the coronal axis of the tibia.

Proximal femoral nail shows better concordance of gait analysis between operated and uninjured limbs compared to hemiarthroplasty in intertrochanteric femoral fractures.

Purpose: The purpose of this study was to compare the results of pedobarographic gait analysis between the patients treated by proximal femoral nail or bipolar partial hemiarthroplasty due to intertrochanteric fractures.

Methods: Thirty-seven patients with a minimum 1-year follow-up who had been operated for intertrochanteric fractures were evaluated clinically, radiologically and with pedobarographic gait analysis. Proximal femoral nail had been performed to 21 patients (group A), whilst 16 patients had been operated by partial bipolar hemiarthroplasty (group B).

Precise placement of lag screws in operative treatment of trochanteric femoral fractures with a new guide system.

Purpose: We assessed the accuracy of a new guide system that we developed to place lag screws in the proper position with the minimum number of attempts for operative treatment of trochanteric femoral fractures.

Methods: A total of 55 consecutive trochanteric femoral fractures were treated with a cephalomedullary nail. The first 27 consecutive patients were treated with the standard operation (group A), while the new guide system was used in the last 28 consecutive patients (group B).
