Gross trunnion failure in an elderly obese patient presenting 10 years after total hip arthroplasty with a cobalt chromium femoral head: A case report.

Introduction: Trunnionosis of total hip prosthesis is defined as corrosion at the head-neck taper junction combined with local tissue reaction. Trunnionosis is a rare complication of total hip arthroplasty (THA) that is often missed in diagnosis. Severe trunnionosis can result in head-neck dissociation, which is called gross trunnion failure (GTF).

Metal Resurfacing Inlay Implant for Osteochondral Talar Defects After Failed Previous Surgery: A Midterm Prospective Follow-up Study.

Background: Treatment of osteochondral talar defects (OCDs) after failed previous surgery is challenging. Promising short-term results have been reported with use of a metal resurfacing inlay implant.

Purpose: To evaluate the midterm clinical effectiveness of the metal implant for OCDs of the medial talar dome after failed previous surgery.

Effects of Pulsed Electromagnetic Fields on Return to Sports After Arthroscopic Debridement and Microfracture of Osteochondral Talar Defects: A Randomized, Double-Blind, Placebo-Controlled, Multicenter Trial.

Background: Osteochondral defects (OCDs) of the talus usually affect athletic patients. The primary surgical treatment consists of arthroscopic debridement and microfracture. Various possibilities have been suggested to improve the recovery process after debridement and microfracture.

Diagnosing, planning and evaluating osteochondral ankle defects with imaging modalities.

This current concepts review outlines the role of different imaging modalities in the diagnosis, preoperative planning, and follow-up of osteochondral ankle defects. An osteochondral ankle defect involves the articular cartilage and subchondral bone (usually of the talus) and is mostly caused by an ankle supination trauma. Conventional radiographs are useful as an initial imaging tool in the diagnostic process, but have only moderate sensitivity for the detection of osteochondral defects.

The Mechanical Functionality of the EXO-L Ankle Brace: Assessment With a 3-Dimensional Computed Tomography Stress Test.

Background: A new type of ankle brace (EXO-L) has recently been introduced. It is designed to limit the motion of most sprains without limiting other motions and to overcome problems such as skin irritation associated with taping or poor fit in the sports shoe.

Purpose: To evaluate the claimed functionality of the new ankle brace in limiting only the motion of combined inversion and plantar flexion.
