Abstract
BACKGROUND Variation in occupational exposure is assumed to have a protective effect against the development of musculoskeletal complaints (MSC), but this common assumption is not strongly supported by the literature. Among musicians, who have a high prevalence of MSC, many play more than one type of instrument (multi-instrumentalism) for many hours a day. Since multi-instrumentalism implies greater variation in ergonomic load of specific musculoskeletal areas than mono-instrumentalism, musicians are a suitable study population to test whether the above assumption is true. PURPOSE To investigate in a sample of professional bass players whether multi-instrumentalists are less likely to have MSC than mono-instrumentalists. METHODS Participants were 141 professional and professional student double bassists and bass guitarists. Demographic, MSC and exposure characteristics were collected online with self-constructed and existing questionnaires. Logistic regression analysis was used to test the association between multi- versus mono-instrumentalism and MSC, adjusted for confounders. RESULTS The prevalence of having MSC in the neck, back, right shoulder area and both wrist areas did not differ significantly between the two groups. Further analysis revealed that the likelihood of having MSC in the left shoulder area was higher in multi-instrumentalists compared to mono-instrumentalists (Odds ratio 0.30, 95% CI 0.119-0.753, p = 0.010). CONCLUSION In this sample of professional bass players, no protective effect of multi-instrumentalism against MSC was found. Multi-instrumentalism was associated with a higher prevalence of MSC in the left shoulder. This result challenges theoretical and clinical assumptions in occupational and pain medicine.

Abstract
PURPOSE To report outcomes of 21 total wrist arthroplasties (TWA) using the Universal 2 prosthesis. METHODS Five men and 14 women aged 44 to 82 (mean, 62) years underwent 21 total wrist arthroplasties for rheumatoid arthritis (n=19) and post-traumatic arthritis (n=2) by a single surgeon using the Universal 2 prosthesis. Pre- and post-operative pain and function were assessed by a single surgeon using the Disabilities of the Arm, Shoulder and Hand (DASH) score and the patient-rated wrist evaluation (PRWE) score. Range of motion, stability, dislocation rate, and neurovascular status were also assessed. Radiographs were evaluated for implant alignment and fit, screw positioning, and implant loosening. RESULTS The mean time to assessment of the range of motion was 3.1 (range, 1.8-3.9) years, and the mean time to assessment of the PRWE score was 4.8 (range, 2.1-7.3) years. The range of motion in each direction and the mean DASH and PRWE scores improved significantly following TWA. Two patients had restricted range of motion, which was treated by manipulation under anaesthetic (after 6 months in one and 8 weeks in the other). One patient underwent excision of a palmar bony bridge. One patient endured extensor pollicis longus rupture and underwent tendon transfer after 5 months. Radiographs revealed no evidence of implant loosening, migration, or malalignment. There was no sign of osteonecrosis in the remaining carpals or metacarpals. CONCLUSION The Universal 2 TWA achieved significant improvement in range of motion and functional outcome of the wrist, with reduced rates of early joint instability, dislocation, and implant loosening, compared to previous implants. The small implant size and cementless design reduce bone loss and osteonecrosis.

Abstract
OBJECTIVE The role of surgery in the clinical management of patients with rheumatoid arthritis (RA)-associated hand dysfunction is still a subject of controversy. The efficacy of surgery in RA-associated hand dysfunction is assessed through an exhaustive review of published studies. METHODS A high-sensitivity search strategy was used to identify in MedLine and CENTRAL original studies related to hand and wrist surgery in RA patients. We selected articles including at least two adult RA patients which evaluated clinical outcomes through an observational or experimental design. Eligible studies were evaluated by standardized criteria. Two investigators independently used a pre-defined form to extract data about patient population, intervention, follow-up and clinical outcomes. Disagreements were discussed and resolved. RESULTS One hundred and ninety-six papers met inclusion criteria. Only five were randomized trials, while most studies followed an observational design, often of poor quality. As such, we could not pool data for statistical analysis; however, we were still able to provide a best evidence synthesis. A positive trend suggesting the efficacy of total carpal arthrodesis and metacarpophalangeal arthroplasty in reducing pain and improving function seemed to emerge from the published studies. CONCLUSIONS Despite recent advances in medical treatment, surgery still plays a role in the clinical management of RA-associated hand dysfunction. However, the majority of the available studies showed methodological flaws that prevented a clear definition of both surgical indications and criteria for choosing any specific procedure. Suggestions for further investigations are also provided.

Abstract
Thirteen wrist arthrodeses were performed for failed wrist implant arthroplasties between 1984 and 1992. Twelve patients were available for review, with an average follow-up period of 28 months. The original arthroplasties consisted of 8 silicone implants and 4 metal-plastic total wrist implants. The surgical method involved a tricortical iliac bone graft and an intramedullary Steinmann pin. There were 7 excellent results, 4 good results, and 1 poor result. All but 1 patient had markedly improved function with no or mild pain. Seven patients had solid fusions and 5 patients had pseudarthroses. Four pseudarthroses occurred at the graft-metacarpal junction and 1 occurred at the graft-radius junction. Each patient with a solid fusion had an excellent result. All graft-metacarpal pseudarthroses were painless and did not limit the patients' activities. There were 17 complications in 9 patients. Wrist arthrodesis can be a successful salvage procedure for failed wrist implant arthroplasty in patients with rheumatoid arthritis. However, the complication rate can be high. Owing to the high incidence of distal graft-metacarpal pseudarthrosis, we recommend using more rigid fixation techniques in patients with failed wrist arthroplasties.

Abstract
We report experimentally produced silicone microparticles (synovitis) in 47 white rabbits and discuss the implications for clinical practice. Silastic HP100 (Dow Corning Wright, Arlington, TN) finger hinges (size 5) were inserted in 20 rabbit's knees. The upper tibia was replaced with Swanson design great toe implants in another 15 rabbits; articular cartilage was removed and endosteal drilling was performed in 6 animals as a "sham" arthroplasty. Small silicone blocks were inserted in the proximal tibial endosteal canal of 6 others. Animals were followed by monthly x-ray films and killed at 2, 4, 6, 12, and 16 months. Implant wear, bone surfaces, and soft tissue were examined under the operating microscope and by light microscopy; implant surfaces were examined with scanning electron microscopy. X-ray changes included reactive endosteal bone formation around implant stems as early as 1 month postoperatively; at 2-3 months the new bone line was clearest but it became progressively homogeneous and less evident. Extensive cortical erosion around the stems was observed in one third of the animals. Neither ossification nor lysis was observed around the silicone block. Proliferative synovitis was found at post-mortem examination beginning after 4 months; femoral condylar erosions were observed in most animals after 12 months. Wherever there was bone destruction, silicone particles were confirmed by x-ray spectrography.

Abstract
This study evaluated the titanium grommets recommended to reduce breakage by protecting hinge implants from bone edges. Silastic HP-100 (Dow Corning Wright, Arlington, TN) flexible finger implants (size 5) were used to replace one knee of 10 rabbits, and implants plus titanium grommets were used in another 10. X-ray films were taken monthly; deaths from each group were 1 animal at 2 and 4 months, 2 animals at 6, and 3 each at 12 and 16 months. X-ray films revealed that 4 of 10 implants from each group had fractured. Silicone fractures occurred identically at the proximal stem-hinge junction in both groups, destruction was always most pronounced at the dorsal surface of the proximal stems. The time from surgery to x-ray film evidence of implant fracture without grommets was an average of 9 months and with grommets 13 months. Although grommets delayed x-ray film evidence of fracture onset, after 14 months all implants in both groups of animals fractured. These findings do not support the hypothesis that grommets prevent silicone hinge implant wear or fracture in this experimental model.

Abstract
The authors determined the outcomes of 18 consecutive Volz total wrist arthroplasties that were followed for an average of 8.6 years. Nine of these wrists were followed for 10 or more years. Fourteen wrists were replaced for rheumatoid arthritis and four for post-traumatic degenerative joint disease. Forty-nine degrees of combined flexion and extension and 25 degrees of combined ulnar and radial deviation were maintained. The balance of wrist motion was dependent upon the design and location of the metacarpal prosthesis. A 24% loss in carpal height (subsidence) occurred during the study period. Four metacarpal components were loose (22%), three of which were placed in patients with degenerative joint disease. One radial component (6%) was loose. Fifteen of 18 wrists (83%) had little or no pain. The three wrists with moderate or severe pain were in patients with degenerative joint disease. There were five (28%) complications. One revision was performed and another was recommended. Overall, the long-term outcome of total wrist arthroplasty was favorable in patients with rheumatoid arthritis.

Abstract
In a study of the results of silicone rubber arthroplasty of the wrist 18 patients (19 operated wrists) were re-examined after a mean follow up of five years. Experience with the ulnar head implant was discouraging, and it was not used in the last eight wrists. This did not affect the outcome, patients having good supination and pronation without pain. The range of motion with the radiocarpal prostheses was 0-70 degrees, mean 39 degrees. Radiological results showed severe subsidence in all patients followed up for more than two years, and prosthetic fracture in five (26%), which was disappointing. Nevertheless the patients had a useful range of motion and all but two were relieved of pain. By the patients' own assessments 16 wrists were considered good, one fair, and two poor. Predictors of failure (prosthetic fracture) were poor alignment before operation, postoperative range of motion of more than 50 degrees, and rupture of the carpal extensor tendon. With these reservations we recommend the silicone spacer as the best solution for most patients with severe problems of the wrist as a result of rheumatoid arthritis.

Abstract
We report seven cases of pathologic fracture in adult patients that were seen an average of 5 years (range from 33 to 114 months) after silicone wrist (three) and trapezial (four) arthroplasty. All patients had initially done well after their operation. At return, all had radiographic evidence of generalized implant and intramedullary bone destruction, the latter always including endosteal scalloping and widening from cortical resorption. These radiographic changes may be less striking than the discrete osteolytic lesions seen after degeneration of carpal implants. Our patients represent examples of pathologic fracture as the end stage of untreated microparticulate synovitis, a consequence of prosthetic wear. Our experience suggests that careful and continuous follow-up justified after insertion of stemmed silicone implants, and that patients should be informed of the potential late complications of this procedure, including pathologic fracture.

Abstract
Clinical and radiographic assessment of the results of 40 Swanson silicone ulnar head prosthesis implants in three different patient groups is presented. Twenty-eight were done for treatment of rheumatoid arthritis, eight for ulnoradial impingement after the Darrach procedure, and four for ulnocarpal impingement resulting from malunited Colles' fractures. Patients were reviewed 12 to 48 months after operation (mean, 29 months). Seventy-eight percent of patients reported relief of pain and improved function. Radiologic examination showed that all patients exhibited resorption of the distal ulna (mean 4.4 mm) and that resorption was worst in the group with rheumatoid arthritis. Bone resorption about the implant predisposed the cap to both side-to-side tilt and pistoning of the prosthesis on supination and pronation. There was a 10% revision rate because of silicone synovitis. Although clinical results remain satisfactory for patients with rheumatoid arthritis and ulnocarpal impingement, the radiologic results suggest that Swanson ulnar head replacement should be restricted to elderly patients with rheumatoid arthritis.

Abstract
Four cases of radius fracture are presented; each was caused by a fall and happened at least 18 months after total wrist arthroplasty. One patient had bilateral fractures occurring 12 months apart. All injuries were initially treated nonoperatively. Nonunion or healing with deformity occurred in three fractures. Revision arthroplasty was done in two cases with satisfactory results, and is being considered for a third.

Abstract
This article describes complications due to an incorrectly positioned Hamas-designed total wrist prosthesis in a 68-year-old woman with rheumatoid arthritis. At operation the median nerve was found to be directly impinged upon by the rim of the distal portion of the prosthesis. There were divisions of the superficialis tendon to all four fingers, the profundus tendon to the index finger, and partial division of the profundus to the long finger. The prosthesis was removed, and the wrist stabilized with a Steinmann pin in the radius and the second metacarpal.

Abstract
The results of 30 Volz total wrist arthroplasties in 23 patients with stage III or stage IV rheumatoid arthritis were reviewed 36 to 106 months after the operation (average 69 months). Sixty percent were rated good or excellent, 27% were rated fair, and 13% were rated poor. Good or excellent results were achieved in 77% with single-prong metacarpal components, but in only 47% of the double-prong group. Wrist imbalance was the primary cause of poorer results with the double-prong metacarpal component. Pain relief and patient satisfaction were achieved in 86% of the cases. Typical radiologic patterns of deterioration were resorption of bone under the collar of the radial component (79%, average 3.7 mm) and metacarpal component loosening (24%). Most patients with component loosening had little or no discomfort. Complications occurred in 12 cases but affected the final outcome in only three patients.
