Evaluation of Outcomes Following Arthroscopic Treatment of Femoroacetabular Impingement Syndrome Across Different Surgeons, Surgical Techniques, and Postoperative Protocols: A Multi-institutional Study.
Orthop J Sports Med
January 2025
Department of Orthopaedic Surgery and Sports Medicine, University of Washington, Seattle, Washington, USA.
Background: Femoroacetabular impingement syndrome (FAIS) is frequently treated arthroscopically with osteoplasty and labral repair. Surgical preferences vary in terms of equipment, technique, and postoperative protocol. Patient-reported outcome measures (PROMs) are valuable tools to assess outcomes across different institutions.

Article Synopsis
- Cementoplasty is a method used for treating fractures, but its effectiveness in weight-bearing long bones is debated; efforts to enhance bone cement strength include altering its chemistry or adding metal reinforcements.
- This study aimed to compare the biomechanical properties of reinforced polymethylmethacrylate-based bone cement with a non-reinforced version by testing two reinforcement methods: using a Kirschner wire and a prestressed steel cable.
- Results showed that both reinforcement techniques significantly increased the flexural strength of the bone cement compared to the non-reinforced version, but no significant difference in strength was found between the two reinforcement strategies themselves.
Minimally invasive balloon-reduction of acute Hill-Sachs-lesions and impression fractures after shoulder dislocation - an experimental approach.

Background: The shoulder is the joint most often affected by dislocations. It is known that bony defects of the glenoid and/or humerus can lead to recurrent dislocations even after arthroscopic shoulder stabilization. To prevent recurrent instability, it appears reasonable to reduce fresh and larger Hill-Sachs lesions (off-track lesions).

Article Synopsis
- The study aims to compare the alpha angles measured using fluoroscopy and ultrasound before and after osteoplasty surgery and to evaluate if ultrasound effectively assesses cam deformity correction.
- Twelve full-body specimens (20 hips) were analyzed using both imaging methods in six consistent positions during pre- and post-operative assessments after performing an open femoral osteoplasty.
- Results showed no significant differences in alpha angles between the two imaging modalities preosteoplasty, suggesting that ultrasound is a reliable alternative for assessing hip morphology.
Foreign Bodies of Dental Iatrogenic Origin Displaced in the Maxillary Sinus - A Safety and Efficacy Analysis of a Retrospective Study.
Ann Maxillofac Surg

Department of Oral and Maxillofacial Surgery, Dental School, Aristotle University of Thessaloniki, Thessaloniki, Greece.
Introduction: Foreign bodies (FB) of the paranasal sinuses are an uncommon clinical entities with the maxillary sinuses being those most frequently affected. According to the literature, 60% of paranasal sinus FB are of iatrogenic origin, while 25% are of traumatic origin. This article aims to present an iatrogenic origin series of cases of FB displaced or projecting into the maxillary sinus.
