Biomechanical simulation of bed turning post-acetabular fracture fixation.
Sci Rep

Department of Orthopaedic, South China Hospital of Shenzhen University, Shenzhen, 518116, Guangdong, China.
Before patients begin out-of-bed exercises following internal fixation surgery for acetabular fractures, turning over in bed serves as a crucial intervention to mitigate complications associated with prolonged bed rest. However, data on the safety of this maneuver post-surgery are limited, and the biomechanical evidence remains unclear. This study aims to introduce a novel loading protocol designed to preliminarily simulate the action of turning over in bed and to compare the biomechanical properties of two fixation methods for acetabular fractures under this new protocol.

Background: Dislocation remains a common complication following total hip arthroplasty (THA). Previous literature has shown that the femoral head-to-neck ratio is essential in hip motion, function, and stability. While large femoral heads and dual mobility bearings have been developed to improve stability, it remains unknown if the ratio between femoral head size to acetabular cup size also plays a role in stability.

Introduction: Total hip arthroplasty (THA) is recognized as one of the most effective surgical procedures for the treatment of end-stage hip arthritis. However, the increasing number of primary THA cases has led to a corresponding rise in the frequency of revision surgeries, which are often more complex and challenging due to severe acetabular bone loss. In such cases, managing Paprosky type 3A and 3B defects requires precise implant design and advanced surgical techniques.

Department of Orthopaedics, Mahatma Gandhi Medical College and Hospital, Jaipur, Rajasthan, India.
Introduction: Low-grade myofibroblastic sarcoma (LGMS) is an atypical and extremely infrequent type of tumor, primary mass being usually present in subcutaneous and soft tissue. Bony involvement is very rare. It has a very high chance of recurrence locally due to its aggressive biological behavior, metastasis in other parts of body is rarely seen.

Purpose: To (1) systematically assess which orthobiologic agents are being used in acetabular labral repairs and (2) report all available outcomes for patients undergoing operative management for labral repairs with orthobiologic agents.
Methods: The PubMed, Embase, and Cochrane databases were queried in August 2023. Articles were included if they used an orthobiologic agent during hip arthroscopy for acetabular labral repair and reported functional outcomes.
