Primary radial head arthroplasty (RHA) produces good or excellent results in approximately 85% of patients. However, complications are not uncommon and have been described in up to 23% of cases.The number of RHA is increasing, and consequently the absolute number of complications is expected to rise as well.

Background: Although revision arthroplasty surgery is a frequently used treatment for failed total elbow arthroplasty (TEA), published results are conflicting. The aim of this systematic review was to provide an overview of the outcomes of revision TEA surgery.

Methods: A systematic literature search was performed in major databases to find articles relating to outcomes after revision of TEA.

Background: The aim of this study was to analyze indications, outcomes, and complications in patients treated with radiocapitellar arthroplasty.

Methods: This prospective analysis of clinical and radiographic results included 16 elbows in 15 patients.

Results: This study included 4 men and 11 women (mean age, 51.

There has been an increase in thrower-specific elbow injuries in recent years. High valgus stresses during the late cocking and acceleration phases of throwing need to be compensated by the flexor pronator muscles as these can exceed the tensile strength of the medial collateral ligament complex. Prevention of injuries is the priority, with a focus on strengthening, reducing throwing frequency, decreasing force, and promoting a technique.

Simple elbow dislocations are usually treated conservatively. Radiographs are negative in simple dislocations. Results are generally good, although a small percentage of patients may develop chronic instability.

Elbow instability is common and may occur after a variety of injuries, including falls or direct blows. Instability can be classified as either acute or chronic. Acute instability is classified as simple (without fracture) or complex (with associated fracture).

Osteoarthritis is the most common joint disease and a major cause of disability. Distinct biological processes are considered crucial for the development of osteoarthritis and are assumed to act in concert with additional risk factors to induce expression of the disease. In the classical weightbearing joints, one such risk factor is an unfavourable biomechanical environment about the joint.

Background: When a surgeon uses a percutaneous volar approach to treat scaphoid waist fractures, central screw placement is complicated by the shape of the scaphoid and by obstruction by the trapezium. In this study, we used radiographs and biomechanical tests to compare the standard volar percutaneous approach with the transtrapezial approach, with regard to central screw placement at the distal pole of the scaphoid.

Methods: Fourteen matched pairs of cadaveric wrists were randomly assigned to two treatment groups.

Purpose: To report the short-term results for posttraumatic total elbow arthroplasty.

Methods: We included patients presenting to our hospital with symptomatic chronic posttraumatic arthritis or deformities of the elbow, aged 55 to 90 years. All patients had reconstruction with a Coonrad-Morrey prosthesis.

Unlabelled: This study aimed to evaluate the long-term results of arthroscopic thermal shrinkage of the anterior capsule in athletes with internal shoulder impingement. In recent years, opinion with regards to the aetiology of internal shoulder impingement has changed significantly. The traditional treatment of internal impingement consisted of debridement of labral and/or undersurface cuff lesions.

A case is presented of a 78-year-old woman who sustained a re-fracture of the distal radius after initial fixation with a volar locking plate. The fracture was located in the mid-portion of the volar plate with palmar apex bending of the plate and signs of median nerve compression. A successful closed reduction was performed without hardware failure.

Percutaneous screw fixation of scaphoid fractures has gained popularity over the years. The disadvantages of a long period of cast immobilisation are avoided and this technique allows a more rapid return to work and sports activities than conservative treatment. Consequently, percutaneous screw fixation is appealing for the young and active population.

Chronic groin pain in athletes is a difficult diagnostic and therapeutic condition. Between March 2004 and December 2009, 241 male athletes (mean age: 25.8 years, range: 16-41) in whom chronic sportsman's hernia was diagnosed, were surgically treated using a standardised technique.

Background: Recent studies report that magnetic resonance imaging (MRI) shows a high incidence of associated injuries in patients with a radial head fracture. This retrospective study describes the clinical relevance of these injuries.

Materials And Methods: Forty patients with 42 radial head fractures underwent a MRI scan after a mean of 7.

Background: A prospective study was established to assess the effect of an intra-articular injection of corticosteroid and local anaesthetic into the acromioclavicular (AC) joint.

Methods: Fifty-eight patients with isolated AC joint symptoms were included. Clinical tests were repeated immediately following the injection, as well as at 1-month follow-up.

Humeral implant design in shoulder arthroplasty has evolved over the years. The third generation shoulder prostheses have an anatomic humeral stem that replicates the 3-dimensional parameters of the proximal humerus. The overall complication rate has decreased as a result of these changes in implant design.

Background: A prospective study was established to assess the sensitivity of the newly described Bell-van Riet (BvR) test for isolated AC pathology, and compare with 4 commonly used clinical tests.

Materials And Methods: The BvR test is essentially the cross-adduction test, with the addition of attempted elevation against resistance. In a positive test, this results in some pain and the inability of the patient to maintain the arm in the adducted and elevated position against resistance.

Background: Chronic longitudinal radioulnar dissociation has been associated with unpredictable and generally unfavorable outcomes. Metallic radial head replacement may address this treatment deficiency.

Methods: Eight patients were treated with a metallic radial head replacement for chronic longitudinal radioulnar dissociation.

Background And Purpose: Radial head fractures are common, and may be associated with other injuries of clinical importance. We present the results of a standard additional MRI scan for patients with a radial head fracture.

Patients And Methods: 44 patients (mean age 47 years) with 46 radial head fractures underwent MRI.

Background: Although the triceps tendon has been used as a graft for ligament reconstruction about the elbow, and has been postulated to be useful as a graft in the treatment of massive rotator cuff tears, no data exists on the tensile properties of the triceps tendon. The purpose of this study was to define the tensile properties of the medial, lateral, and central thirds of the triceps tendon, in order to examine its potential as an autograft for upper extremity pathology.

Materials And Methods: Ten fresh frozen upper extremity specimens were used.

Introduction: Recent literature shows an increased mean age of female patients with radial head fractures compared with male patients with radial head fractures. However, data on epidemiology of radial head fractures and specifically in relation to age distribution and male-female ratios of radial head fracture are scarce.

Materials And Methods: A retrospective database search was performed to identify all patients with a radial head fracture over a 3-year period.

Background: Documentation of the long-term effectiveness of 3-part unlinked elbow replacement is limited. The value of replacing the radial humeral articulation has not been addressed to any extent in the currently available literature.

Materials: A retrospective study of patient charts and radiographs of 37 patients receiving 46 primary Pritchard ERS arthroplasties between 1983 and 1992 were reviewed.

Background: Pain in the buttock radiating to the popliteal fossa associated with hamstring weakness can be caused by tethering of the sciatic nerve to the proximal hamstring tendons. Contraction of the hamstring muscles produces traction on the sciatic nerve and subsequent symptoms.

Hypothesis: Surgical release of the proximal hamstring tendons, in particular from the sciatic nerve, will improve symptoms and function.

The goal of this study was to look at the pattern of osteophyte distribution on a 3-dimensional computed tomography scan of patients with symptomatic osteoarthritis in the elbow. We recruited 22 consecutive patients with symptomatic osteoarthritis of the elbow for the study. Three-dimensional reconstructed anterior, posterior, medial, and lateral views of the elbow were reviewed.
