The Burch-Schneider Reinforcement Ring : 200 cases over a 40-year period with a mean follow-up of 11 years.

Aims: The Burch-Schneider Reinforcement Ring (BSRR) was developed to manage significant acetabular defects and prevent protrusion in complex primary and revision total hip arthroplasties. This study evaluates the long-term performance of the BSRR over four decades, focusing on survival, patient-reported outcomes, radiological evidence of loosening, complication rates, and factors associated with implant failure.

Methods: We conducted a retrospective analysis of 200 hips treated with the BSRR at the Cantonal Hospital of Fribourg, Fribourg, Switzerland, from January 1974 to December 2018.

The PENG Block in Elective Primary Anterior Total Hip Arthroplasty Is Associated with Reduced Length of Stay: A Multidisciplinary Prospective Randomized Double-Blinded Controlled Trial.

Background: The pericapsular nerve group (PENG) block has been shown to reduce pain and opioid consumption in posterior total hip arthroplasty (THA). The present study assessed the effects of the PENG block versus a placebo on postoperative (1) pain, (2) morphine consumption, and (3) length of stay in patients undergoing primary anterior THA.

Methods: This was an institutional review board-approved, single-center, parallel-group, prospective, randomized, double-blinded, controlled trial of patients undergoing primary anterior THA between June 2022 and April 2023.

[Femoroacetabular impingement : treatment].

The concept of femoro-acetabular impingement (FAI) rests on three pillars: cam-deformity, pincer-deformity and abnormal femoral torsion. Several treatment modalities exist, ranging from conservative management to open or arthroscopic surgery. The type of treatment depends on the pathomorphology, the severity of symptoms, thepatient's age and the extent of the degenerative lesions.

[Femoroacetabular impingement in 2024 : concept and diagnosis].

Femoroacetabular impingement (FAI) is a condition that predominantly affects young people between the ages of 20 and 40. It is characterized by hip pain associated with reduced range of movement of the hip joint. If left untreated, FAI leads to osteoarthritis.

Persistent femoral neck non-union despite valgus intertrochanteric osteotomy: Relevance for secondary cam-type impingement.

Unlabelled: Valgus intertrochanteric osteotomy is a well-established treatment in delayed union of femoral neck fractures as it converts shear forces into compression forces. Non-union of the femoral neck fracture may persist following valgus intertrochanteric osteotomy, and secondary femoroacetabular impingement (FAI) may be a contributing factor.

Case: We report one case of persistent femoral neck non-union after treatment by valgus intertrochanteric osteotomy with concomitant secondary cam-type impingement from fracture callus as a possible cause for ongoing insufficient healing.

Surface repair of the femoral head using press-osteochondral autograft transfer.

Aims: Hyaline cartilage has a low capacity for regeneration. Untreated osteochondral lesions of the femoral head can lead to progressive and symptomatic osteoarthritis of the hip. The purpose of this study is to analyze the clinical and radiological long-term outcome of patients treated with osteochondral autograft transfer.

Nonunion of an Undisplaced Lateral Compression Type 1 Pelvic Ring Fracture due to Interposition of a Tension-Free Vaginal Tape: A case report.

Case: Nondisplaced lateral compression type 1 fractures of the pelvic ring are usually treated nonoperatively. We describe a case of nonunion after conservative treatment of such a fracture in a healthy 59-year-old female patient due to the interposition of a tension-free vaginal tape in the fracture gap. An anterior intrapelvic approach with plate osteosynthesis was used to stabilize the fracture once the tape was removed from the fracture gap.

Reliability and Reproducibility of a Novel Grading System for Lesions of the Ligamentous-Fossa-Foveolar Complex in Young Patients Undergoing Open Hip Preservation Surgery.

Background: Several classification systems based on arthroscopy have been used to describe lesions of the ligamentum teres (LT) in young active patients undergoing hip-preserving surgery. Inspection of the LT and associated lesions of the adjuvant fovea capitis and acetabular fossa is limited when done arthroscopically but is much more thorough during open surgical hip dislocation. Therefore, we propose a novel grading system based on our findings during surgical dislocation comprising the full spectrum of ligamentous-fossa-foveolar complex (LFFC) lesions.

Radial Nerve Neuropraxis due to Compression by C-Arm Fluoroscopy in Spine Surgery: A Case Report.

Introduction: Peripheral nerve injury is a well-known surgical complication related to the position of the patient. Moreover, in spine surgery, prone position for prolonged period places the patient at increased risk. The aim of this study was to report a case of a radial nerve neuropraxis due to compression by C-arm fluoroscopy during spine surgery.

Pre-operative localization of solitary pulmonary nodules with computed tomography-guided hook wire: report of 181 patients.

Background: Video-assisted thoracic surgery (VATS) is currently performed to diagnose and treat solitary pulmonary nodules (SPN). However, the intra-operative identification of deep nodules can be challenging with VATS as the lung is difficult to palpate. The aim of the study was to report the utility and the results of pre-operative computed tomography (CT)-guided hook wire localization of SPN.
