This retrospective study assessed the outcomes of 21 patients (16 male and 5 female, mean age 39 years) with advanced Kienbock's disease treated by resection of the proximal carpal row. They were clinically reviewed. The mean follow-up was 67 months, with all but two patients having had a follow-up of 2 years. No or mild pain was being experienced by 13 patients, moderate pain by 3 and severe pain by 5. Grip strength increased from 19 kg pre-operatively to 26 kg postoperatively (or 65% of the normal contralateral side). There was a slight increase of mobility. The DASH score was 22 points (range 0-78) and the Patient Rated Wrist Score (PRWS) was 30 points (range 0-84). Two patients developed Complex Regional Pain Syndrome which was ongoing at the time of review and one developed a superficial wound infection. Proximal carpal row resection arthroplasty gave satisfactory results in patients with advanced Kienbock's disease.

Key pinch force was measured preoperatively and at follow-up (mean 25 months) in patients treated for basal joint arthritis by either trapziectomy with ligament reconstruction and tendon interposition (n=26) or total joint arthroplasty (n=27). There was a significant increase in key pinch strength with both treatments, but no difference between the two treatments. Total joint arthroplasty does not appear to produce stronger key pinch than trapziectomy with ligament reconstruction and tendon interposition.

The outcome of total wrist arthrodesis was reviewed in 36 patients with osteoarthritis after a minimum follow-up of 4 years. Pain relief was not complete, and although 20 were pain free at rest, only six were pain-free during manual activity. Grip strength was 63% of the contralateral side and the DASH score remained high. Only 21 of the 34 could be re-employed. The mean time off work was 14 months. Complications were numerous and additional surgery was required in 21 patients.

Three failed Sauvé-Kapandji procedures were salvaged using an ulnar head prosthesis. At 7-22 month follow-up, all three patients were much improved. However, the stem of one implant subsequently fractured in a fall and this implant had to be removed.

We reviewed 14 patients treated with either an ulnar or a hypothenar fat flap for recurrent carpal tunnel syndrome and scar tenderness. Nine patients were satisfied and there were few complications. One patient had delayed skin healing and another developed a hypertrophic scar.

In a prospective study we evaluated the results of 272 distal radial fractures by their involvement of the distal radioulnar joint. Impaired function following altered anatomy at the distal radius can be explained by dysfunction of the distal radioulnar joint. Ulnar styloid avulsions contribute to a poorer result because of their effect on distal radioulnar joint function.

A case of avascular non-traumatic necrosis of the metacarpal head in a 36-year-old woman is reported. Treatment was by curettage of the necrotic bone and packing with cancellous grafts.

In order to evaluate diagnostic and therapeutic wrist arthroscopy we analyzed 129 arthroscopies with a follow-up of at least 6 months. Seventy-seven arthroscopies were performed for therapeutic purposes; 52 arthroscopies were diagnostic. There were diagnostic benefits in 55 arthroscopies (42.5%), therapeutic benefits in 29 arthroscopies (22.5%), combined diagnostic and therapeutic benefits in 39 (30%) and no benefits in six (5%). In 65 cases of the therapeutic group (with preoperative diagnosis) the authors found that the arthroscopy had been worthwhile. For the diagnostic group without a preoperative diagnosis, an arthroscopic diagnosis was made in 44 cases. Complications occurred in two patients: one tendon incision over a Kirschner wire in the therapeutic group and one superficial infection in the diagnostic group.

In patients with chronic wrist pain of more than 6 months duration, arthroscopy may reveal fraying of the ulno-triquetral and ulno-lunate ligaments. This can be a sign of longstanding triquetrolunate dissociation. We present a prospective study in which frayed ulno-triquetral (UT) and ulno-lunate (UL) ligaments were sought on wrist arthroscopy and correlated with longstanding triquetro-lunate (TL) rupture.

51 wrists of 30 embalmed cadavers have been used to perform an anatomical and radiological study relating cartilaginous and ligamentous lesions of the wrist with sex, age, ulnar variance (UV) and the state of the triangular fibrocartilage complex (TFCC) in an elderly population (mean 76.6 years). Two-thirds of all wrists (66%) showed cartilaginous lesions, mainly on the lunate (22, or 44%). The TFCC was perforated in 23 wrists (46%), and most were central degenerative perforations. Correlations were found between ulnar variance and TFCC thickness (P < 0.05) and ulnar variance and TFCC perforations (P < 0.05). A significant relation was observed between age and proximal row intercarpal ligamentous ruptures (P < 0.05) and between age and ulnar variance (P < 0.05). No statistical correlation was seen between ulnar variance and cartilaginous lesions on the lunate (P < 0.05) in this slightly ulnar negative population (mean-0.37 mm).

We retrospectively compared two similar groups of patients who underwent either endoscopic decompression of the carpal tunnel (single portal technique, 44 patients) or open decompression (58 patients) during 1 year in our department. To find out whether there was any subjective difference between the results of the two techniques, we sent each patient a questionnaire and received a 95% response. No major complications occurred. Three endoscopic decompressions had to be abandoned, and open release was performed. We could not demonstrate any significant difference in relief of symptoms and return to work between the two groups. Patient satisfaction at 6 to 18 months follow-up was high with both techniques.

Based on five observations of recurrent carpal tunnel syndrome, a distally incomplete section of the flexor retinaculum can be identified on clinical grounds: the wrist flexion test becomes negative and the tourniquet test still remains positive.

Five cases of symptomatic acquired positive ulnar variance are described. All cases occurred due to premature physeal closure of the growth plate in teenage girl gymnasts. All cases demonstrated ulnocarpal impingement, for which we describe a clinical test. Arthroscopic assessment of the wrist allowed us to assess the integrity of the TFCC (triangular fibrocartilaginous complex) and decide on the most appropriate surgery. Two patients needed distal ulna recession and one needed shaving for a TFCC perforation, with a good result.

A case of pseudomalignant osseous tumour of the soft tissues of the finger is reported. The benign diagnosis is confirmed by the histologically characteristic zone phenomenon.

In a five-year-old girl, successful revascularisation of her right index finger was achieved after a 23-hour ischaemia period. The short-term result was satisfactory, with complete survival, protective sensibility and recovering mobility.
