Endoscopic Technique: Sciatic Neurolysis and Piriformis Tendon Release for Treating Piriformis Syndrome.

Piriformis syndrome (PS) is an underdiagnosed condition, caused by entrapment of the sciatic nerve by the piriformis muscle tendon and adhesions in the deep gluteal space. We present a step-by-step endoscopic technique with the patient in a prone position through a posterior approach. This approach provides improved orientation for tracking the sciatic nerve from distal to proximal, facilitating the release of all adhesions and concluding with a piriformis tendon release.

Background: The sphericity of the femoral head is a metric used to evaluate hip pathologies and is associated with the development of osteoarthritis and femoral-acetabular impingement.

Aim: To analyze the three-dimensional asphericity of the femoral head of asymptomatic pediatric hips. We hypothesized that femoral head asphericity will vary significantly between male and female pediatric hips and increase with age in both sexes.

Best practices on patient education materials in hip surgery based on learnings from major hip centers and societies.

Patient education is important as it gives patients a better understanding of the risks and benefits of medical and surgical interventions. Developing communication technologies have completely changed and enhanced patient access to medical information. The aim of this study was to evaluate available patient education materials (PEMs) regarding hip surgery on the websites of major hip societies and centers.

Editorial Commentary: Socioeconomic Disparities in Health Outcomes: The Patient Behind the Procedure.

Equitable delivery of health care, regardless of sex, race, ethnicity, or socioeconomic status, is shown to be generally unsuccessful. The benefits of standardized treatment protocols to increase clinical consistency and efficiency are clear-but risk inferior outcomes if not adapted to account for socioeconomically disadvantaged patients. Underinsured patients face challenges accessing continuous and comprehensive care, even during the postoperative period.

Variations in the Anatomic Morphology of the Scapular Spine and Implications on Fracture After Reverse Shoulder Arthroplasty.

Introduction: This study evaluates the role of anatomic scapular morphology in acromion and scapular spine fracture (SSAF) risk after reverse shoulder arthroplasty (RSA).

Methods: Twelve scapular measurements were captured based on pilot study data, including scapular width measurements at the acromion (Z1), middle of the scapular spine (Z2), and medial to the first major angulation (Z3). Measurements were applied to 3D-CT scans from patients who sustained SSAF after RSA (SSAF group) and compared with those who did not (control group).

Knotless Tensionable Anchors: Versatility, Tips, and Tricks.

Arthroscopic surgery, including implants and advanced techniques, continues to advance in the field of orthopaedics. The evolution of suture anchors has undergone design changes, passing from first-generation metal anchors, biodegradable materials, different plastic polymers, to all-suture constructs. Knotless technology also has been found to be a more reproducible method and have comparable outcomes with those found using knotted anchors.
