A 30-year-old amateur goalkeeper sustained simultaneous dislocation of the proximal and distal interphalangeal joints of the ring finger and of the proximal interphalangeal joint of the middle finger following a hyperextension injury. This was reduced under a local anaesthetic. Neighbour finger strapping and early mobilisation achieved an excellent functional outcome when reviewed at eight weeks after the initial injury.

Comparative Study
Treatments of osteoarthritis of the distal radioulnar joint: long-term results of three procedures.
Sixty-one wrists in 61 patients with osteoarthritis of the distal radioulnar joint treated by three consecutive procedures (20 Darrach, 25 Sauvé-Kapandji and 16 hemiresection-interposition arthroplastic procedures) were retrospectively evaluated. We preferred to perform Darrach's procedure in even the early stages of osteoarthritis of the distal radioulnar joint prior to introduction of Sauvé-Kapandji and hemirestion-interposition arthroplastic procedures. Subsequently the hemirestion-interposition arthroplasty was indicated when the triangular fibrocartilage cartilage was intact or could be reconstructed and the Sauvé-Kapandji when the triangular fibrocartilage complex could not be reconstructed or there was positive ulnar variance of more than 5 mm even though the triangular fibrocartilage complex was functional. ⋯ There were many post-operative complications following the Darrach's procedure. Darrach's procedure is better indicated for severe osteoarthritic changes of the distal radioulnar joint in elderly patients. We believe the operative indications between the Sauvé-Kapandji procedure and hemiresection-interposition arthroplasty are best determined prior to surgery by the existence and status of the triangular fibrocartilage complex and the amount of the positive ulnar variance.

Case Reports
Superficial radial nerve compression caused by a parosteal lipoma of proximal radius: a case report.
The superficial radial nerve might be compressed or injured at various anatomical sites along its course in the forearm. Most of the superficial radial nerve neuropathy are caused by pathological lesions such as trauma, a mass or tight band at the distal third of the forearm. Wartenberg's syndrome is the most common cause of sensory radial entrapment at the distal forearm. ⋯ The patient reported total relief of the neurological symptom post-operatively. This rare case demonstrates the unique characteristics of parosteal lipoma with unusual superficial radial nerve neuropathy at the proximal radius. This report reminds us that there is the possibility of superficial nerve compression caused by tumour mass over the proximal third of forearm.

Comparative Study
Adhesion formation after flexor tendon repair: comparison of two- and four-strand repair without epitendinous suture.
Increased handling, increased bulk at the repair site and an increase in external suture material may affect adhesion formation and gliding after tendon repair. A previous study(1) showed no significant difference in biomechanical or histopathological measurement of adhesion formation in two- and four-strand repairs combined with an epitendinous suture in the chicken model. In the present study, the flexor digitorum profundus tendon of the middle toe of 47 broiler chickens was cut and repaired with either a single (two-strand) or double (four-strand) modified Kessler core suture without epitendinous suture and immobilised for four weeks. ⋯ Results did not differ from the previous study which used an epitendinous suture. Adhesion formation is not necessarily increased when multi-strand techniques are used, nor by the placement of an epitendinous suture if care is taken with surgical technique. Individual healing response introduces more variability than an increase in tendon handling by an experienced surgeon.

From September 1996 to September 2001, 37 adult patients were diagnosed with chronic triangular fibrocartilage complex (TFCC) tears with distal radioulnar joint (DRUJ) instability in our clinic. They had all received the procedure of TFCC reconstruction with partial extensor carpi ulnaris (ECU) combined with or without ulnar shortening. There were 36 males and one female in the study with a mean age of 22.4 years. ⋯ Eleven of the 37 patients rated their wrists "excellent", 22 rated "good", and four rated "fair". Overall, a total of 33 patients (89%) rated satisfactorily and returned to work or sport activities. Therefore, TFCC reconstruction with partial ECU tendon combined with or without ulnar shortening procedure is an effective method for post-traumatic chronic TFCC tears with DRUJ instability suggested by this study.
