There is little information available at present regarding the mechanisms of failure of modern metallic radial head implants. Between 1998 and 2008, 44 consecutive patients (47 elbows) underwent removal of a failed metallic radial head replacement. In 13 patients (13 elbows) the initial operation had been undertaken within one week of a fracture of the radial head, at one to six weeks in seven ...

INTRODUCTION We retrospectively reviewed the results of total elbow arthroplasty in patients with rheumatoid arthritis of the elbow followed for a minimum of two years. METHODS Between September 1999 and March 2001, seven patients with rheumatoid arthritis of the elbow were treated with total elbow arthroplasty using the semi-constrained Coonrad-Morrey elbow replacement prostheses. One patien...

The diagnosis of tuberculosis of the elbow is often missed in the early stages, so that irreversible osteoarticular destruction may occur. The authors describe their experience with 48 elbows in 47 patients. Most patients were in the first three decades of life. All patients presented with pain, swelling and loss of motion. Sixteen elbows had discharging sinuses. Eight elbows had a palpable sup...

Background Capitellar osteochondritis dissecans (OCD) in skeletally immature athletes has often been seen in baseball players and gymnasts. The choice of surgical procedure for unstable lesions in skeletally immature athletes remains controversial. Purpose To investigate functional outcomes and radiographic changes in the midterm to long-term postoperative period after arthroscopic (AS) resec...

BACKGROUND Baseball pitchers have adaptive changes in the soft tissues of the throwing elbow. HYPOTHESIS High school baseball pitchers would show adaptive changes in the ulnar collateral ligament (UCL), such as calcifications and hypoechoic foci, thickening, and increased ulnohumeral joint laxity, on dynamic ultrasound (DUS). STUDY DESIGN Cross-sectional study. LEVEL OF EVIDENCE Level 3. ...

AIMS The aim of this study was to describe the morphological features of posterolateral radiohumeral (RH) plica in asymptomatic subjects and in patients with elbow osteoarthritis using ultrasonography (US). MATERIAL AND METHODS The control group included a total of 100 healthy elbows (51 subjects) and the study group consisted of 22 elbows (22 patients) with osteoarthritis confirmed clinicall...

A general robotic mechanism was presented for in-pipe inspection oflevel pipes with varied diameter or curved pipelines. The robot employed three legs comprised of parallelogram linkages mechanism which enables adapting to various elbow joints in the piping systems. The curvatures in pipeline are the most important constraints in front of the robot through navigation process. To study the adapt...
