Abstract
Assessment of hand strength is used in a wide range of clinical settings especially during treatment of diseases affecting the function of the hand. This investigation aimed to determine age- and gender-specific reference values for grip and pinch strength in a normal Swiss population with special regard to old and very old subjects as well as to different levels of occupational demand. Hand strength data were collected using a Jamar dynamometer and a pinch gauge with standard testing position, protocol and instructions. Analysis of the data from 1023 tested subjects between 18 and 96 years revealed a curvilinear relationship of grip and pinch strength to age, a correlation to height, weight and significant differences between occupational groups. Hand strength values differed significantly from those of other populations, confirming the thesis that applying normative data internationally is questionable. Age- and gender-specific reference values for grip and pinch strength are presented.

Abstract
OBJECTIVE To cross-culturally adapt the Patient-Rated Wrist Evaluation form (PRWE) into German (PRWE-G) and to evaluate its reliability and validity. METHODS A cross-cultural adaptation of the PRWE was carried out, according to established guidelines. 103 patients, who had undergone resection interposition arthroplasty (RIAP) for carpometacarpal osteoarthritis approximately 6.2 years earlier, completed a questionnaire booklet containing the PRWE-G, the Short Form 36 (SF-36), the Disabilities of Arm, Shoulder, and Hand (DASH); they also underwent clinical assessment with the Hand Function Index (HFI, Keitel) and Custom Score including grip and pinch strength tests. The results were used to assess the criterion and construct validity of the PRWE-G. To measure the re-test reliability, 51 patients completed a second PRWE-G within 2 weeks. RESULTS The test-retest reliability of the PRWE-G was acceptable for the pain and function sub-scales and for the global score, with intraclass correlation coefficients of 0.78-0.87. The PRWE-G showed a high internal consistency (Cronbach's alphas of 0.92-0.97 for the scales and the total score). The typical error of measurement for the global score was 8.1 points, giving a minimal detectable change (MDC<inf>95%</inf>) of approximately 22.5 points. The PRWE-G scores correlated well with those of the DASH (r=0.82, p<0.001) but less well with those of the physical component summary of the SF-36 (r=0.53, p<0.001) and not at all with the mental component summary scores of the SF-36 (r=0.04, p>0.05). The PRWE-G scores correlated moderately with certain clinical findings of the HFI, Custom Score, and grip/pinch strength tests (r=0.30-0.59, p<0.001). CONCLUSION The PRWE-G represents a valid and reliable instrument to evaluate self-rated outcome in German-speaking patients with hand and wrist pathology.

Abstract
OBJECTIVE To Estimate the probability of treatment success 1 year after a total shoulder arthroplasty by developing a model based on preoperative clinical factors. METHOD Between June 2003 and December 2006, 140 patients undergoing shoulder operations were assessed for age, gender, current rheumatoid arthritis, Short Form (SF) 36 physical and mental sum scores, previous shoulder operations, the Disabilities of Arm, Shoulder and Hand (DASH) symptom and function scores, the Shoulder Pain and Disability Index (SPADI), and insurance status. One year after the operation a Constant score of 80 or more out of 100 indicated successful treatment. Patient variables were analyzed with a logistic regression model augmented in a stepwise manner and bootstrapped 100 times. Variables selected at least 33 times were incorporated into a final model and the Area under the Receiver Operating Characteristics Curve (aROC) was calculated. RESULTS There were 47/140 (33.6%) successful treatments. The probability of success was reduced in patients with previous shoulder operations (Odds Ratio [O.R.] 0.17, 95% Confidence Interval (95%CI) 0.04-0.85; P=0.03) and older than 75 years (O.R. 0.21, 95%CI 0.05-0.77; P=0.02). The probability of success increased in patients with a higher SF 36 mental sum score (O.R. 1.03, 95%CI 0.96-1.09, P=0.42) and a higher DASH function score (O.R. 1.05, 95%CI 1.02-1.07, P=0.001). The aROC was 0.79 (0.70-0.88) indicating that the model has a high predictive capacity. CONCLUSION Once validated this model based on four preoperative clinical factors offers a prediction of whether a patient will respond to treatment 1 year after total shoulder arthroplasty.

Abstract
Since the introduction of the first National Arthroplasty Register in Sweden in 1975, many other countries have tried to adopt the successful Scandinavian system. However, not all have overcome the political and practical difficulties of establishing a working register. We have surveyed the current registries to establish the key factors required for an effective database. We have received detailed information from 15 arthroplasty registers worldwide. The legal conditions under which they operate together with the methods of collection and handling of the data differ widely, but the fulfilment of certain criteria is necessary achieve a high degree of completeness of the data to ensure the provision of statistically relevant information.

Abstract
OBJECTIVE To cross-culturally adapt the Shoulder Pain and Disability Index (SPADI) from English into German, and to test the reliability and validity of the German version. METHODS Cross-cultural adaptation of the SPADI was performed according to international guidelines. One hundred and eighteen patients who had undergone shoulder arthroplasty, on average 4 yr previously, completed a questionnaire booklet containing the German SPADI, the Short Form 36 (SF-36), the Disability of the Arm, Shoulder and Hand (DASH) questionnaire, and the American Shoulder and Elbow Surgeons (ASES) questionnaire for the shoulder to assess SPADI's construct validity. One week later, they completed the SPADI again to assess test-retest reliability. RESULTS The six-step cross-cultural adaptation procedure revealed no major problems with the content or language. The intraclass correlation coefficients for the individual items of the SPADI were between 0.68 and 0.89, and that for the SPADI total score was 0.94. The SPADI total score showed a correlation of 0.61-0.69 with the SF-36 physical scales, of 0.88 with the DASH and of 0.92 with the ASES. CONCLUSIONS The German SPADI is a practicable, reliable and valid instrument, and can be recommended for the self-assessment of shoulder pain and function.

Abstract
BACKGROUND Histone acetylation/deacetylation has a critical role in the regulation of transcription by altering the chromatin structure. OBJECTIVE To analyse the effect of trichostatin A (TSA), a streptomyces metabolite which specifically inhibits mammalian histone deacetylases, on TRAIL-induced apoptosis of rheumatoid arthritis synovial fibroblasts (RASF). METHODS Apoptotic cells were detected after co-treatment of RASF with TRAIL (200 ng/ml) and TSA (0.5, 1, and 2 micromol/l) by flow cytometry using propidium iodide/annexin-V-FITC staining. Cell proliferation was assessed using the MTS proliferation test. Induction of the cell cycle inhibitor p21Waf/Cip1 by TSA was analysed by western blot. Expression of the TRAIL receptor-2 (DR5) on the cell surface of RASF was analysed by flow cytometry. Levels of soluble TRAIL were measured in synovial fluid of patients with RA and osteoarthritis (OA) by ELISA. RESULTS Co-treatment of the cells with TSA and TRAIL induced cell death in a synergistic and dose dependent manner, whereas TRAIL and TSA alone had no effect or only a modest effect. RASF express DR5 (TRAIL receptor 2), but treatment of the cells with TSA for 24 hours did not change the expression level of DR5, as it is shown for cancer cells. TSA induced cell cycle arrest in RASF through up regulation of p21Waf1/Cip1. Levels of soluble TRAIL were significantly higher in RA than in OA synovial fluids. CONCLUSION Because TSA sensitises RASF for TRAIL-induced apoptosis, it is concluded that TSA discloses sensitive sites in the cascade of TRAIL signalling and may represent a new principle for the treatment of RA.

Abstract
BACKGROUND Patients with elbow destruction due to rheumatoid arthritis (RA) or trauma (PT) were compared to population-based normative data and to each other after total elbow arthroplasty. PATIENTS AND METHODS Pain, function, and biopsychosocial health were multidimensionally assessed by the generic Short Form 36 (SF-36), the condition-specific Disabilities of the Arm, Shoulder and Hand questionnaire (DASH), and the Patient Related Elbow Evaluation form (PREE) instrument and analyzed by uni- and multivariate methods. RESULTS Compared to normative values, the examined 59 RA patients were significantly affected in the function scales of the SF-36 and in all DASH scales. The 20 PT patients were worse than the norm only in the DASH function. Function was lower in RA than in PT in the SF-36 scales and in the DASH (RA: 44.4, PT: 70.3, p<0.001). This difference was less distinct in the PREE. CONCLUSION Total elbow arthroplasty led to a pain-free outcome and normal quality of life, but failed to restore complete function. Functional deficits were larger in the RA patients and could also be measured by the SF-36, possibly due to polyarticular affection.

Abstract
For the reconstruction of destroyed metacarpophalangeal (MP) joints in rheumatoid arthritis, the Swanson silicon spacer is still the golden standard. However, long-term follow-up reveals an increasing number of complications, particularly mechanical failure. In order to deal with these problems a number of new, biomechanically different silicone implants have been designed. Among these, the NeuFlex prosthesis has a preflexed hinge of 30 degrees in relation to the shaft axis, a more palmar lying center of rotation and a rectangular hinge with a collarlike platform against the bony surfaces. In a prospective study, the early results of the first thirteen patients operated with the NeuFlex arthroplasty are reported. All patients suffered from rheumatoid arthritis with destruction of the MP joints. The mean follow-up was 12.3 months. A total of 37 joints were replaced. All patients were female with an average age of 56 years. Postoperative reduction of pain, measured on a visual analog scale with the maximum of 10 (VAS), decreased from 6.6 to 0.7 (p < 0.001). Jamar grip strength improved from 4.2 kg preoperatively to 9.9 kg postoperatively (p < 0.005). Range of motion improved from 37 degrees to 57 degrees (p < 0.0001) as a result of a reduction in active extension deficit which reduced from 35 degrees to 15 degrees postoperatively. Ulnar drift was reduced from 20.2 degrees to 3.4 degrees at follow-up (p < 0.005). Radiological evaluation showed no implant failure, no subsidence, and no signs of inflammatory reaction. Overall the NeuFlex silicone implants show encouraging early results which must be confirmed in the long term.

Abstract
A reversed Delta III total shoulder prosthesis was retrieved post-mortem, eight months after implantation. A significant notch was evident at the inferior pole of the scapular neck which extended beyond the inferior fixation screw. This bone loss was associated with a corresponding, erosive defect of the polyethylene cup. Histological examination revealed a chronic foreign-body reaction in the joint capsule. There were, however, no histological signs of loosening of the glenoid base plate and the stability of the prosthetic articulation was only slightly reduced by the eroded rim of the cup.

Abstract
Artificial joint replacement has found a firm place in orthopaedic surgery since its first introduction in the late 1960s. While the initial fixed bearing implants tended to progress to early loosening, the development of so-called "sloppy joints" has seen a major advance in the survival and success rate of this arthroplasty. The surgical approach and technique have also been modified in such a way as to allow a complete ventral release of a flexion contracture, while at the same time preserving the integrity of the extensor mechanism. In this way, the improvement of the biomechanics of the implant combined with diligent surgical technique have enhanced this procedure dramatically. Between 1978 and 1999, 305 GSB 3-type prosthesis were implanted, with the underlying pathologies being rheumatoid arthritis (77%), posttraumatic arthritis (21%) and degenerative arthritis (2%). The range of motion could be significantly improved from the pre-operative state for extension as well as flexion. This was even more obvious in the rheumatoid than in the posttraumatic situation. The survival rate for this type of implant was 90% at 10 years, with the implants after rheumatoid surgery faring somewhat better than those of the posttraumatics. Alternative treatment options, such as resection arthroplasty, distraction arthroplasty, or arthrodesis, are nowadays employed only in rare cases where a previous infection, personal preference or an inability by the patient to co-operate in a rehabilitation program have to be considered. The overall functional results of these types of treatments seem to be inferior to that of elbow arthroplasty. Therefore, this procedure is recommended not only for advanced degenerative and rheumatoid pathologies, but also in cases of posttraumatic arthrosis.

Abstract
The aim of this study was to determine the value of scaphoidtrapezium osteoarthritis (ST osteoarthritis) as an early sign of calcium pyrophosphate dihydrate disease (CPDD) in a cohort of patients undergoing surgery for osteoarthritis of the first carpometacarpal joint. We examined whether patients with cartilage calcification of the wrist at the time of operation had ST osteoarthritis, indicating CPDD at an earlier time (retrospective study), and whether patients with ST osteoarthritis but without cartilage calcification at the time of surgery develop radiological or clinical signs of CPDD at a later time (prospective study). From 1 January 1989 to 31 December 1995 a total of 169 patients (from an orthopaedic clinic) with a diagnosis of osteoarthritis of the first carpometacarpal joint were included in the study; 167 underwent surgery and two were treated without. Of the 16 patients showing calcification on surgery and therefore included in the retrospective study, 12 had prior radiographs, of which eight showed ST osteoarthritis. Among these, four had no concomitant cartilage calcification in the prior radiographs. Of the 32 patients in the prospective group having ST osteoarthritis but no calcifications at the time of surgery, 27 could be clinically examined. Of these, two showed cartilage calcifications on the follow-up radiographs of the hands. The presence of ST osteoarthritis is a helpful diagnostic finding for the diagnosis of CPDD, especially in cases without radiographic cartilage or fibrocartilage calcification of the wrist. ST osteoarthritis may then point to the correct diagnosis.

Abstract
OBJECTIVE To analyze the expression pattern of osteoclast differentiation factor (ODF) and its contribution to osteoclastogenesis in rheumatoid arthritis (RA). METHODS The expression of ODF was analyzed by reverse transcriptase-polymerase chain reaction (RT-PCR) in RA synovial fibroblasts (RASF) isolated from 7 RA patients and in normal skin fibroblasts. Using RNA probes specific for ODF, in situ hybridization was performed. Immunohistochemical double labeling for CD68 was applied to characterize the ODF-expressing cells. ODF protein and messenger RNA (mRNA) expression by RASF with or without 1,25(OH)2D3 was studied by Western blot analysis and quantitative real-time PCR. In addition, we performed coculture experiments with RASF and normal peripheral blood mononuclear cells with or without 1,25(OH)2D3. RESULTS By RT-PCR, ODF mRNA expression was found in all RASF investigated, but not in normal skin fibroblasts. In situ hybridization revealed that in RA synovial tissues, ODF mRNA was expressed mainly in the lining layer and at sites where synovium was attached to bone. Immunohistochemical double labeling demonstrated ODF mRNA expression mainly in CD68-fibroblast-like synoviocytes and CD68+ multinucleated osteoclast-like cells. By Western blotting, all RASF expressed ODF protein. However, different levels of ODF expression were found in the RASF from different patients. Interestingly, RASF expressing higher levels of ODF induced a larger number of osteoclast-like cells than did RASF expressing only low levels of ODF. Although 1,25(OH)2D3 did not alter the levels of ODF expression in RASF on either Western blot or quantitative real-time PCR, osteoclastogenesis required the presence of 1,25(OH)2D3. CONCLUSION The present results suggest that activated RASF, by expressing ODF, play an important role in rheumatoid bone destruction. Moreover, the data provide evidence that RASF not only activate osteoclasts, but also contribute directly to osteoclastogenesis.

Abstract
In a retrospective study, 75 patients with tendon suspension-interposition arthroplasty were compared with 27 patients with prosthetic replacement of the trapezium for CMC I osteoarthritis. A significant decrease in pain and an increase in subjective strength was observed in both groups. The extent of change was not significantly different between the two groups. Although there was radiographically less proximalisation of the thumb in the patient group with silastic interposition, objective strength and range of motion was not significantly different between the two groups. Since the results of trapeziectomy for the treatment of degenerative osteoarthritis of the base of thumb with or without silicone interposition are comparable, the use of silastic implants, with their inherent complications, no longer seems to be justified. There might be a place for the condylar type of implants in low-demand rheumatoid patients, in whom as much bone stock as possible should be preserved.

Abstract
Joint replacement is an established method in the treatment of destroyed, painful, proximal interphalangeal joints. A palmar approach was used in which the main collateral ligaments were preserved, allowing immediate active rehabilitation with enhanced primary lateral stability. Fifty-nine proximal interphalangeal joint silicone arthroplasties in 38 patients with a minimum followup of 12 months were reviewed. Thirty-eight of the 59 joints had implantation from a palmar approach and 21 joints from a dorsal approach. The two groups were well-matched in terms of indication, preoperative range of motion, and patient age. No significant increase in the range of motion was found in either of the patient groups, with an overall average range of motion of 51 degrees postoperatively. There was also no significant difference in the postoperative stability in the two patient groups. The choice of surgical approach at the proximal interphalangeal joint level for the silastic type of implants does not appear to be important. With more sophisticated types of implants in which the integrity of the collateral ligaments is crucial, a palmar approach might be beneficial.

Abstract
The authors introduce a new functional classification of rheumatoid arthritis of the wrist. Unlike the classifications used today, it includes the aspect of the natural course of rheumatoid arthritis. The goal of this paper is to identify radiologic indicators that will classify rheumatoid arthritis into stable forms of the disease (Types I and II) and unstable forms of the disease (Type III). Of 144 wrists examined, the first available radiograph and the radiograph obtained at the time of the first surgery were assessed. The indicators measured were: carpal height ratio, ulnar translocation, radial rotation, and scapholunate dissociation. Noting the changes that occurred each year in these indicators, it was possible to identify a significant difference between stable forms (Types I and II) and unstable forms (Type III) for the parameters carpal height ratio, ulnar translocation, and scapholunate dissociation. The distribution of the indicators allowed the definition of three values: the 100% value, the cut off point, and the lower threshold value. Combining the three radiologic parameters at those values markedly enhanced the possibility to classify rheumatoid arthritis of the wrist. With the help of the three radiologic indicators carpal height ratio, ulnar translocation, and scapholunate dissociation, it is possible to classify wrists with an early stage of rheumatoid arthritis according to the Schulthess classification. The early identification of destabilizing forms of rheumatoid arthritis becomes possible, making the choice and timing of the surgical intervention easier. Wrists with a progressive unstable form of rheumatoid arthritis may be stabilized earlier.

Abstract
Trapeziectomy for the treatment of trapeziometacarpal arthritis is an in vivo model of an isolated lesion of the scaphotrapeziotrapeziod ligament complex. We analysed the radiological changes in the wrist retrospectively in 86 patients after trapeziectomy. On standardized PA and lateral films the revised carpal height ratio, the radiolunate angle, the scapholunate angle and ulnar translation were compared pre- and postoperatively. None of these parameters showed a statistically significant change after operation. Grouping the patients into shorter (< 36 months) and longer (> 36 months) follow-ups also failed to show any significant differences.

Abstract
Instability is one of the most common complications after shoulder arthroplasty. The literature cites subluxation or luxation to occur between 0% and 38% in various studies. Instabilities may present either as subluxation or frank dislocation, and may be directed in an anterior, posterior, inferior or, depending on the state of the rotator cuff, cranial direction. The stability of any shoulder joint is given by the balance of the muscles directing the forces around the shoulder joint in association with the passive stabilizers of the shoulder joint capsule as well as the bony contours between glenoid and humeral head. Any disturbance of this delicate balance will lead the shoulder into instability, particular so if bony erosion patterns such as posterior glenoid wear in osteoarthritics will develop subluxation early on. Therefore implantation of any prosthesis is required to be done in the appropriate version as to avoid secondary instability through the prosthetic components. In the study undertaken here instability was found to be the most common complication in 44 shoulder revision surgeries. The result with an average Score of 41.9 recorded after Constant demonstrates that the excellent and good results obtained with primary arthroplasties can not be expected in revision surgery. Posterior instability may be present just as well as the more easily observed anterior instability. Separate to frank luxation or instability is the late cranialisation of the rotator cuff deficient shoulder which, although resulting in many cases in superior anterior subluxation, will mostly be seen as a late complication after arthroplasty.

Abstract
Shoulder arthroplasty has since it's more widespread introduction in the early seventies found a general acceptance as an excellent tool for treating late stage arthritis of the shoulder joint. The indications will vary from primary osteoarthritic disease to inflammatory diseases such as rheumatoid arthritis, or psoriatric arthritis. It is also used as a primary tool in multifragmented shoulder fractures, which can not be restored anatomically, or are felt at risk for avascular necrosis. The surgeon setting out for this procedure has to decide whether a total arthroplasty is required in cases with glenoid destruction, or at risk of developing secondary degenerative changes in the glenoid early on. A hemiarthroplasty will only replace the humeral side of the joint, but while well accepted in the fracture patient, the arthritic patients tend to fare better with a total joint replacement for pain relief.

Abstract
The reported frequency of involvement of the rheumatoid ankle and hindfoot varies between 9% and 70%. Fusion of the ankle joint, the subtalar, talonavicular, or calcaneocuboidal joint (Chopart's joint) or all of them is the preferred method of treatment for severe rheumatoid involvement causing pain, instability, and/or severe deformity. Ankle arthroplasty is indicated rarely. Pantalar arthrodesis is performed more frequently than talonavicular fusion or ankle fusion. Reported rates of fusion after compression arthrodesis of the ankle joint vary from 65% to 90%, averaging 80% to 85%. Higher success rates of as high as 95% were obtained with internal lag screw fixation as proposed by Wagner. The result of various combinations of arthrodesis (n = 54) of the ankle joint, the subtalar joint, and Chopart's joint in 43 patients with rheumatoid arthritis operated on in a 10-year period from 1984 through 1993 are presented. In all cases internal fixation by lag screws according to Wagner was used with a modified lateral approach incorporating osteotomy of the distal fibula. The technique is described in detail. Solid fusion was obtained in 21% of the cases after 8 weeks, in 9% of the cases after 12 weeks, and in 92% of the cases after 16 weeks. In 8% (3 patients) revision because of delayed union or nonunion eventually led to bony fusion. Postoperative pain, walking capacity, gait, and the subjective outcome were assessed. Complications occurred in 16%, revision was performed in 11.6% of the cases; in all cases healing was obtained. Overall patient satisfaction was 93%.

Abstract
The world literature (1986 to 92) reports an amazingly high complication rate of elbow arthroplasty, amounting to 43%. Accordingly, we also find a high revision rate (18% on average) and a considerable rate (15%) of permanent complications. These figures do not correspond to our own experience with the GSB III (Gschwend/Scheier/Bähler) elbow prosthesis, a sloppy hinge with flanges on the lower and anterior part of the distal humerus. Our respective figures of complications are two to four times lower for rheumatoid elbows. When complications are discussed, a clear distinction of the type of prosthesis is mandatory, because linked or nonlinked and nonconstrained or semiconstrained prostheses have specific complications. The following complications are discussed separately: loosening (radiologic and clinical), ulnar neuropathy, infection, dislocation and subluxation, uncoupling, intraoperative bone fractures, and failure of the implant. The possible causes are analyzed, and means to avoid or treat these complications are discussed. We conclude that even in the long term ( > 10 years), results obtained with elbow arthroplasty are approaching those of hip and knee arthroplasty.

Abstract
The rate of infection reported in recent publications is 0.8% after shoulder arthroplasty and ten times higher (8.1%) after elbow arthroplasty. The figures for shoulder arthroplasty correspond well with our own rate of revision for infection of 0.5% after 363 primary shoulder replacements. However, our average rate of revision for infection (1.8%) after 278 GSB-III elbow arthroplasties was considerably lower and included rheumatoid as well as post-traumatic indications. Our experience concerning etiologic factors, nature, diagnosis, treatment options, and long-term consequences of superficial and deep infections after shoulder and elbow arthroplasty are discussed for each joint separately and in relation to the literature.

Abstract
Rheumatoid arthritis is basically a disease of the synovium and involves the synovium-lined sheaths that surround many of the tendons in the hand and wrist. Proliferative synovitis affects the tendons, infiltrates the tendons, causes formation of nodules, changes their ultrastructure, and eventually leads to spontaneous rupture. The three common sites of tendon sheath involvement are the dorsal and palmar aspect of the wrist, and the palmar aspect of the digits. Early tenosynovectomy can prevent tendon ruptures and should therefore be the cornerstone of treatment. Once spontaneous rupture has occurred, early diagnosis and treatment are important to prevent further rupture. Reconstruction of isolated ruptures of extensor or flexor tendons gives good results. Multiple tendon ruptures, however, are difficult to treat and have a worse prognosis. The severity of the patient's disease and the degree of articular involvement have a greater effect on the outcome of surgery than reconstruction techniques. Our current approach to the management of this difficult problem is presented.

Abstract
In an own prospective series with 18 endoscopic decompressed carpal tunnel syndrome patients the problems with this new release technique are described. Although most of the patients did clinically well, four major complications, all with revision operations, were observed. Two cases still suffer residual problems. Due to these complications we stopped the endoscopic technique and returned to the traditional surgical treatment of open carpal tunnel decompression.

Abstract
Existing classifications of rheumatoid wrist involvement are based on the degree or stage of destruction of the wrist. We suggest to classify rheumatoid wrist involvement according to the type rather than the extent of destruction. In order to recognize the nature of wrist destruction at an early stage of the disease as well as in late stages, a continuous series of 63 patients with definitive rheumatoid arthritis for over 20 years and wrist involvement of more than ten years were analysed both clinically and radiologically. Based on radiological appearance of the late stage, three different types of wrist involvement can be recognized: Group I--Type I: rheumatoid arthritis--ankylosis Group II--Type II: rheumatoid arthritis--(secondary) osteoarthrosis Group III--Type III: rheumatoid arthritis--destabilization Spontaneous ankylosis is characteristic for patients with a juvenile onset of rheumatoid arthritis, however, it also occurs in patients with a later consent of the disease. Patients in group II (type II) demonstrate a tendency to develop secondary arthrosis. Articular surface cartilage loss progresses at a rate which remains in relative equilibrium with processes typical of arthrosis, stabilizing the carpal architecture. In group III (type III), all wrists develop an unstable radiocarpal joint as evidenced by ulnar and palmar subluxation of the carpus relative to the radius and progressive loss of carpal height. When early surgical treatment is considered, it is crucial to recognize patients with type III wrist destruction. For these patients, an osseous stabilizing procedure is essential for long-term stabilization of the wrist. It is important that any evidence of progressive loss of carpal height or of ulnar radiocarpal translocation not be ignored.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Degenerative arthritis of the wrist as a consequence of chronic scapho-lunate instability or chronic scaphoid non-union follows very specific patterns. Joint destruction occurs primarily in the radio-scaphoid and in the luno-capitate joints while the radio-lunar joint is preserved. Treatment by partial carpal fusion between capitate, scaphoid and lunate aims at reconstruction of correct length of the central column and restoration of normal carpal height by reducing the dorsiflexed lunate bone, thereby decompressing the painful radio-scaphoid joint. We have carried out the procedure in 21 cases. At follow up (19 months) 17 patients were free of pain and 4 patients experienced major improvement but had some residual pain. The mean range of motion of the wrist was 57 degrees, representing a loss of 34% of preoperative range of movement. Bony union was achieved in all cases. All patients returned to their former occupation. Partial carpal fusion for treatment of SLAC-wrist and scaphoid nonunion has proven successful with respect to pain relief and partial preservation of wrist motion avoiding complete fusion or arthroplasty of the wrist.

Abstract
Serious impingement syndromes of the shoulder unresponsive to conservative measures can be relieved by means of the approved open anterior acromioplasty. However, the rise of shoulder arthroscopy allowed the same procedure to be performed arthroscopically. Based on an accurate indication the outcome of arthroscopic subacromial decompression may be considered as equally successful as that obtained by the open procedure. The advantages of the arthroscopic approach are: a significantly less gross destruction of the deltoid and--as a result--a reduced rehabilitation period a smaller incision and the possibility of an arthroscopic inspection of the joint prior to decompression For the repair of complete tears of the rotator cuff the arthroscopic procedure will provide less satisfactory long-term results. For those cases the open reconstruction will remain the treatment of choice.

Abstract
Spontaneous flexor tendon ruptures in rheumatoid arthritis are associated with flexor tenosynovitis and/or with attrition due to bony prominences in the carpal tunnel. The commonest bony prominence observed is the distal pole of a rotated scaphoid. We are reporting the case of an eighty-year-old woman with long-standing rheumatoid arthritis who presented with the inability to actively flex both the interphalangeal and the metacarpophalangeal joints of the right index finger, with preservation of passive motion. There was also loss of active flexion of the interphalangeal joint of the right thumb. Roentgenograms revealed a marked dorsal intercalated segment instability (DISI) pattern in both wrists associated with advanced joint destruction and collapse. Surgical exploration revealed total rupture of the FDS and FDP of the index finger and of the FPL, as well as partial rupture of the flexor tendons of the long finger. Rupture of the FPL was found to be due to attrition on the relatively common finding of a prominent and malrotated scaphoid. Ruptures of the flexor tendons of the index and long fingers appeared to be caused by a markedly prominent palmar protrusion of the lunate. Surgical repair was undertaken, including correction of the DISI deformity and reconstruction of carpal height by radiolunate fusion from a palmar approach. In addition the tubercle of the scaphoid was resected, and the FDS tendon of the ring finger was transferred to the distal stump of the FDP of the index finger; the FPL tendon was not reconstructed as arthrodesis of the interphalangeal joint of the thumb was planned at a later date.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Among the various alternative forms of treatment of digital tip amputations, replantation of the amputated tip as composite graft or conservative treatment (healing by secondary intention) are of special interest for the management of fingertip injuries in children. From 1986 until 1987, the authors treated thirteen fingertip amputations in children between one and eight years of age (mean 3.5 years). In twelve cases, the amputated tip was reattached as composite graft, one injury healed by secondary intention. Twelve children were reexamined according to a prospective protocol after a mean follow-up time of 3.4 years. In three cases, primary healing of the replanted tip could be observed, in eight cases partial necrosis and superficial mummification preceded complete healing. At follow-up, seven cases presented with an anatomical tip, four with a slight asymmetry. Distal phalangeal length was identical to the opposite side, but in two cases a maximal loss of length of 2 mm was observed. Fingernails showed no significant deformities, although nail bed injuries had occurred in 90% of the cases. Sensitivity was normal in all cases. Child and parents considered the final result excellent in 75% and good in 25%. Reattachment as composite graft or conservative treatment for management of fingertip amputations in children (Zone I to III according to Rosenthal) is recommended and discussed.

Abstract
Dislocations and fracture dislocations of the tarsometotarsal joint are uncommon (only 30 cases have been treated in our hospital in a 20-year period). The late results of tarsometotarsal injuries in 20 patients have been reviewed. The average follow-up was 3.8 years (range 8 months to 20 years). Methods of treatment were either open (n = 15) or closed (n = 5) reduction with (n = 18) or without (n = 2) internal fixation and cast immobilization (n = 10). Late results clearly correlate with the quality of reduction. An open procedure is usually necessary to achieve anatomical reduction. Diagnostic and operative problems are discussed.

Abstract
Surgical therapy and the common surgical procedures for the rheumatoid hand are presented: synovectomy, boutonnière deformity, swan-neck deformity, arthroplasty, and surgical therapy of the rheumatoid thumb. The indications, early and late results, and the prophylactic value of synovectomy are discussed and compared with synoviorthesis (intra-articular injection of radioisotopic beta-emitters) in early stages of synovitis. In general, radioisotope synovectomy has reduced the need for early operative synovectomy. If synoviorthesis has no significant effect or if biomechanical factors are predominant in the affected joint (tenosynovitis, massive distension of the capsule and extensor mechanism or large masses of fibrin), then operative synovectomy is indicated. Multicenter studies have confirmed that pain can be relieved and joint swelling reduced by synovectomy for over 10 years after the operation. However, no significant preventive or retarding effects could be proven with regard to the progression of deformity or further radiologic changes. The risks in tenosynovectomy are minimal and the prognosis for improved function and prevention of ruptures is excellent. Restorative procedures on tendons are discussed in conjunction with restoration of joint function. Pathogenetic mechanisms of boutonnière and swan-neck deformities and their therapeutical consequences (soft tissue procedures and arthroplasty of the respective joints) are discussed. Because of the unpredictability of joint resection arthroplasty, many attempts have been made to develop joint prostheses. Surgical experience with cemented components, constrained hinges and prostheses with a fixed axis has been disappointing and forbids their routine clinical use. The most widely used device is the silastic spacer developed by Swanson, a silicone rubber implant acting as flexible hinge to maintain the joint relationship and improve resection arthroplasty. Several authors have obtained good long-term results using the Swanson silastic prosthesis for MP and interphalangeal arthroplasty. However, the silastic spacer still leaves room for improvement, which is particularly evident in patients with constitutional or drug-induced (steroid hormones) ligamentous laxity where bone resorption can be seen due to the piston effect and abrasion of the silicone as well as to sinking and often breakage of the prosthesis. Attempts to prevent this effect are reported. To obtain good functional results with MP arthroplasty, adequate function of the interphalangeal joints and thumb is essential.(ABSTRACT TRUNCATED AT 400 WORDS)

Abstract
The use of a silastic implant in resection arthroplasty of the carpometacarpal joint of the thumb allows the joint space to be preserved. With the Swanson type arthroplasty relief of pain, good function, as well as stability and improved pinch force can be obtained, avoiding the consequence of carpal instability by narrowing of the joint space associated with resection of the trapezium alone or in combination with tendon interposition arthroplasty. The two main problems associated with Swanson arthroplasty are prosthetic dislocation and longterm stability of the prosthesis itself. The joint surface of the prosthesis wears out asymmetrically, and mild to severe foreign body reactions can be seen in the carpal bones, mainly the scaphoid. Clinical and radiological results of a series of 77 operations in 65 patients from 1975-1981 are presented and discussed.
