Purpose: To address the null hypothesis that surgeons shown radiographs of little finger metacarpal neck fractures with measured fracture angulation would recommend surgery as often as surgeons shown unmarked radiographs. Methods: Members of the Science of Variation Group, an international collaboration of fully trained orthopedic and trauma sur...
Article
Background and purpose: A programme based on eccentric exercises for treating subacromial pain was in a previous study found effective at 3-month follow-up. The purposes of the present study were to investigate whether the results were maintained after 1 year and whether the baseline Constant-Murley score, rotator cuff status and radiological find...
Article
The purpose of this study was to determine the minimal important change (MIC) of improvement in the Constant-Murley score in patients with long-standing subacromial pain and in subgroups of patients with subacromial pain with and without rotator cuff ruptures. The MIC was estimated by the anchor-based MIC distribution method, which integrates an an...

Background Eccentric exercises have been successfully used in the treatment of Achilles and patellar tendinopathies, as well as lateral epicondylalgia. No studies have explored the same treatment for medial epicondylalgia (golfer's elbow). Methods Twenty consecutive adults with a clinical diagnosis of medial epicondylalgia were treated with eccentr...
Article
Treatment of intra-articular fractures of the distal humerus in the elderly is challenging. In patients with very distal fractures and severe comminution, primary arthroplasty has been advocated. Recently, a few reports have described promising results of hemiarthroplasty. This study describes the medium-term results of using the Kudo humeral impla...
Article
Arthroscopic synovectomy is safe and reliable, with mild postoperative morbidity. The rationale of a surgical synovectomy is to excise inflamed synovium and thereby, remove as much effusion and inflammatory substrate as possible. In most cases, arthroscopic synovectomy is performed as an outpatient procedure. The technique has also been used for ot...

Full-text available
Mechanisms of injury to ulnar-sided ligaments (stabilizing the distal radioulnar joint and the ulna to the carpus) associated with dorsally displaced distal radius fractures are poorly described. We investigated the injury patterns in a human cadaver fracture model. Fresh frozen human cadaver arms were used. A dorsal open-wedge osteotomy was perfor...
Article
Full-text available
Injury to the triangular fibrocartilage complex associated with distal radius fracture may cause symptoms of ulnar instability. Assessed by a radioulnar stress test, increased laxity of the distal radioulnar joint has in two previous studies been depicted to be associated with poorer outcome. This prospective study of 40 adults investigates the cor...
Article
Full-text available
Few authors have considered the outcome after acute traumatic rotator cuff tears in previously asymptomatic patients. We investigated whether delay of surgery, age at repair, and the number of cuff tendons involved affect the structural and clinical outcome. 42 patients with pseudoparalysis after trauma and no previous history of shoulder symptoms...

We treated 4 female patients (mean age 80) with complex intraarticular acute fracture of the distal humerus with a Kudo humeral component, i.e. a hemiarthroplasty. All fractures were considered impossible to treat with open reduction and internal fixation. At mean 10 (3-14) months, 3 patients had an excellent result and 1 a good result according to...
Article
Synovectomy may be considered for the treatment of chronic wrist arthritis. The indications for wrist synovectomy are, however, not clearly defined. Open synovectomy has been reported to provide good pain relief for a relatively long time but can be associated with loss of mobility. Arthroscopic synovectomy seems equally reliable in terms of sympto...

Fifty-five elbows in 53 patients affected by lateral epicondylitis for more than a year were operated on with lateral extensor release. Fifty-one patients (53 elbows) were followed-up 90 months postoperatively by two independent observers using Verhaar's score and the subjective grading scheme described by Svernlöv and Adolfsson. According to Verha...
Article
Arthroscopic synovectomy is a safe outpatient procedure with minimal postoperative morbidity. In patients who have rheumatoid arthritis and possibly also in patients who have JRA, SLE, and postinfectious arthritis, a long period of increased comfort and improved function can be anticipated. The procedure may be considered in post-traumatic cases wi...
Article
There is no definitive evidence for the efficacy of the physical therapy interventions used for patients with impingement syndrome. The purpose of this study was to compare manual acupuncture and continuous ultrasound, both applied in addition to home exercises, for patients diagnosed with impingement syndrome.
