[Idiopathic arthritis of the finger joints].

Degenerative arthritis of the finger joints is a very common disease in middle-aged and elderly patients, in females more frequently than in males. Concerning differential diagnosis rheumatoid arthritis and related conditions, gout, calcinosis, tumors and tumor-like lesions must be considered. Therapy is not necessary in every case. Usually treatment is required if the disease causes pains, joint instability or disabling deformity. Conservative treatment such as diet, physiotherapy, orthotics, local physical and antiphlogistic drug treatment or systemic application of non-steroid antiphlogistics should be preferred. Operative procedures such as removal of osteophytes, arthrodesis or arthroplasty are indicated if conservative treatment fails.

[Periarthritis calcarea of the finger joints].

Calcium deposits close to finger joints are seen very often and are common in systemic diseases. There are also calcium deposits with no relation to other symptoms and therefore diagnosis is difficult. Between 1984-1988 we have analysed twelve such cases and explained the differential diagnosis and therapy. It seems important that these cases with typical clinical and radiologic findings are self-limiting and restitutio ad integrum is common without any therapy.

The motion analysis system and goniometry of the finger joints.

The application of a video-based motion analysis system for goniometry of finger joints during measurement of the fingertip motion area has been assessed. The results indicate that the motion analysis system is reliable for angular measurements of finger joints that are comparable with those obtained by conventional goniometer. The advantages of using the motion analysis system is that it can record and show the changes in angle of all finger joints continuously during finger motion.

The prevalence of palpable finger joint nodules in diffuse idiopathic skeletal hyperostosis (DISH). A controlled study.

The presence of clinically palpable finger joint nodules (Heberden's and Bouchard's nodes) was documented in 123 consecutive cases with diffuse idiopathic skeletal hyperostosis (DISH) of the thoracic spine and 191 matched DISH negative controls. The prevalence of palpable finger joint nodules was almost twice as frequent in cases with spinal DISH compared to controls (46% versus 31%, chi 2 = 7.67, P less than 0.01; multivariate adjusted odds ratio OR = 1.84; 95% CI: 1.14-2.98). This increase was most marked at the proximal interphalangeal joint, in males and in patients up to the age of 65 years. In addition and independent of other variables such as hyperostotic features, age and sex, the prevalence of palpable finger joint nodules was about twice as high in probands with a history of physically heavy work compared to those without (43% versus 26%, chi = 9.18, P less than 0.005; multivariate adjusted odds ratio OR = 2.10; 95% CI: 1.26-3.52). From these results we conclude that DISH should be considered as an independent risk factor in the development of finger joint nodules.

A cartilagenous graft as an adjunct to finger joint implant arthroplasty.

A method is described which is proposed to prolong the functional life of a Silastic finger joint endoprosthesis which has been shown to fail because of abrasion and cutting by the recipient bones. Swanson design Silastic finger joint prostheses were implanted into the knee joints of rabbits. The technique of simultaneously transplanting ear cartilage to the prosthetic implant bed was tested for the purpose of protecting the prostheses from wear and eventual failure. The clinical, radiographic, gross, and histologic results of the animals implanted for 1, 3, and 6 months show that the cartilage graft remains viable and it proliferates. The cartilage provides a smooth, gliding surface with normal appearing joint fluid surrounding the Silastic implant. Control limbs, with no cartilage grafts, had thinner, fibrous tissue encapsulating the implants. The presence of the cartilage reduced the amount of prosthetic wear particles observed in the tissue sections, thus indicating a protective function. The rabbit model developed an osteoarthritis that was caused by the prostheses in its knee joints and was unaffected by our cartilage grafting procedure. The success of our cartilage grafts, in the presence of such an arthritis, provides the impetus for its clinical use in arthritic human finger joints. Further studies are necessary to determine the clinical feasibility of a cartilage grafting technique and its efficacy in reducing implant failure in human finger joints.

Tension band arthrodesis of finger joints: a retrospective review of 76 consecutive cases.

Arthrodesis of finger joints is a reliable method of treating finger joint instability and arthritis. Tension band arthrodesis is an effective method of stable fixation that uses readily available and inexpensive materials. Because fixation is rigid, patients are allowed to move adjacent joints, usually within 1 week after surgery. The results of 76 tension band arthrodesis procedures performed since 1982 in 63 patients were reviewed. Follow-up ranged from 6 to 38 months. The average time to radiographic fusion was 12 weeks (range, 4 to 64 weeks). One joint failed to fuse and developed a stable, asymptomatic nonunion; thus the fusion rate was 99%. Technical problems that occur with the method include nonparallel pin placement and penetration of pin tips, leading to painful impingement of the soft tissues. A pin-placement guide has been developed to minimize these problems.

Chondroitin sulfate: S/DMOAD (structure/disease modifying anti-osteoarthritis drug) in the treatment of finger joint OA.

A total of 119 patients were included in a randomized, double-blind, placebo-controlled trial in order to assess the S/DMOAD properties in OA of chondroitin sulfate (CS 4&6, 3 x 400 mg/day, Condrosulf IBSA, Lugano, CH). Posteranterior roentgenographies of the interphalangeal (IP) joints were carried out at the start of the study and at yearly intervals. This enabled the investigators to document the radiological progression of the anatomical lesions in the pathological finger joints over a 3-year period. It was shown that the progression of OA in the IP finger joints in an individual can be determined by the evolution of his finger joints through previously described anatomical phases: 'N' (not affected), 'S' (classical OA), 'J' (loss of joint space), 'E' (erosive OA) and 'R' (remodeled joint). Structure/disease-modifying anti-OA drug (S/DMOAD) properties were searched for by assaying the number of patients developing OA in previously normal IP joints ('N' > 'S'), or progressing through the described anatomical phases of the disease ('S' > 'J', 'S' > 'E', 'J' > 'E', 'S' > 'R', 'J' > 'R', 'E' > 'R'). In the CS 4&6 group we observed a significant decrease in the number of patients with new 'erosive' OA finger joints. This result is particularly important since OA of the finger joints becomes a clinical problem (pain, functional loss) when 'S' joints progress to 'J' and especially 'E' phases. During and after these 'E' phases, joints will remodel and show the nodular deformities characteristic of Heberden's and Bouchard's nodes. Treated patients were protected against erosive evolution.

The value of contrast-enhanced color Doppler ultrasound in the detection of vascularization of finger joints in patients with rheumatoid arthritis.

OBJECTIVE: A prospective study was performed to assess the usefulness of contrast-enhanced color Doppler ultrasound (CDUS) in the evaluation of intraarticular vascularization of finger joints in patients with rheumatoid arthritis (RA). METHODS: We investigated 198 finger joints in 46 patients with RA, and 80 finger joints in 10 healthy volunteers. Joints with varying levels of clinical activity of inflammation were classified as being active, moderately active, or inactive. CDUS was performed with a high-frequency multi-D linear array transducer. A microbubble-based ultrasound (US) contrast agent (Levovist; Schering, Berlin, Germany) was intravenously infused. Doppler findings were rated on the basis of both unenhanced and contrast-enhanced CDUS images. RESULTS: Healthy joints showed no intraarticular vascularization on either unenhanced or contrast-enhanced CDUS. Unenhanced CDUS detected intraarticular vascularization in 7 (8%) of 83 inactive joints, in 31 (52%) of 60 moderately active joints, and in 32 (58%) of 55 active joints. Contrast-enhanced CDUS detected intraarticular vascularization in 41 (49%) of 83 joints with inactive RA, in 59 (98%) of 60 joints with moderately active RA, and in all 55 joints with active RA. Detection of intraarticular vascularization was improved by administration of the microbubble-based US contrast agent (P < 0.001). Contrast-enhanced CDUS demonstrated differences in intraarticular vascularization between joints with inactive RA and those with active RA (P < 0.001), between joints with inactive RA and those with moderately active RA (P < 0.001), and between joints with moderately active RA and those with active RA (P < 0.001). CONCLUSION: The use of a microbubble-based US contrast agent significantly improved the detection of intraarticular vascularization in the finger joints of patients with RA. This technique seems to be a useful adjunct in the assessment of disease activity.

Menstrual cyclicity of finger joint size and grip strength in patients with rheumatoid arthritis.

Daily measurements of finger joint size, grip strength, and body weight have been made throughout 2 complete menstrual cycles in 7 female patients with rheumatoid arthritis and 6 healthy female controls. Sine wave analysis showed significant individual cyclical rhythms (p less than 0.05) for finger joint size (5 patients, 4 controls), nude weight (5 patients, 3 controls), and grip strength (4 patients, 3 controls). In addition analysis of group data, on the assumption of a 28-day cycle, showed a significant cycle for grip strength in the rheumatoid patients, with a nadir at 28 days. In the normal subjects much of the cyclical variation in finger joint size could be explained by changes in weight (median 49.5%), but this was not so in patients with rheumatoid arthritis (median 2.8%). These findings suggest the existence of a cyclical variation in disease activity in rheumatoid arthritis.

Contribution of the extrinsic and intrinsic hand muscles to the moments in finger joints.

OBJECTIVE: The purpose of this current work is to develop a method of estimating force produced by the extrinsic and intrinsic hand muscles, and to estimate the contribution of these muscles to the finger joint moments. DESIGN: Experimental methods and a biomechanical model were developed for the estimation of (a) moments produced at finger joints, and (b) contribution of the intrinsic and extrinsic muscles to the moments, (c) forces of the extrinsic and intrinsic muscles within individual fingers. BACKGROUND: Because of the differential insertions of the extrinsic flexors, it is possible to isolate their mechanical effect at finger joints. METHODS: During the experiment, the location of force application was varied in parallel along individual fingers. The points of force application were on the distal phalanx, at the distal interphalangeal joint, or at the proximal interphalangeal joint. RESULTS: When the point of force application was varied in the proximal direction from the distal phalanx to the proximal interphalangeal joint the moment at a given joint decreased. The intrinsic and extrinsic muscle forces were dependent on the experimental conditions. The extrinsic muscles were the major contributors in counterbalancing finger joint moments when the point of force application was distal beyond the proximal interphalangeal joint. CONCLUSION: This current work provides both an experimental protocol and a biomechanical model that allows estimation of the contribution of the intrinsic and extrinsic muscles to finger joint moments. RELEVANCE: This study suggests ways of identifying the source of functional deficiency in the hand.

Occupational use of precision grip and forceful gripping, and arthrosis of finger joints: a literature review.

A systematic review of arthrosis of finger joints in relation to occupational exposure revealed 11 epidemiological studies and 13 case reports. All studies but one were cross-sectional rendering demonstration of causation problematic. The reviewed literature also had drawbacks relating to exposure classification, confounding and non-attendance. Four studies showed an association between extensive use of precision grip and development of arthrosis of the distal interphalangeal joints of fingers. Two studies found an association between forceful gripping and the occurrence of arthrosis involving the metacarpophalangeal joints. Arthrosis of the proximal interphalangeal joints and first carpo-metacarpal joints was not related to any specific occupational task. Well-designed studies are needed to further elucidate this possible occupational hazard.

New instruments, bone liners, and tray for finger joint arthroplasty.

Titanium circumferential grommets have been developed for finger joint arthroplasty that fit on the base of the silicone implant stems to protect the flexible hinge from tearing and fracture. To facilitate grommet insertion, new intramedullary bone rasps have been devised with a reverse cutting tooth pattern, an extended shaft for an improved view of the surgical field, and a redesigned cutting head to allow for grommet insertion. Surgical accessibility and ease of recognition have been facilitated by the development of color-coded sizers. All of the instruments necessary for finger joint surgery are available in a molded tray that has also been redesigned with a transparent lid and clearly labeled compartments for accurate determination of instruments and implant sizers.

Radiologically defined osteoarthrosis in the finger joints of adult residents of Zagreb.

Degenerative changes in the finger joints were studied in 550 Zagreb inhabitants, above the age of 45. The sample was selected by the method of unproportional stratified choice according to age and sex. Radiographs of both hands were taken and osteoarthrosis on the proximal and distal interphalangeal joints was graded according to the five-point Kellgren-Lawrence scale. Body weight, height and arterial blood pressure were measured and occupational work load was evaluated. The prevalence of osteoarthrosis in the finger joints was significantly higher in women (40.9%) than in men (24.8%). It increased with age so that 18.7% of men and 15.0% of women aged 45-54 had finger osteoarthrosis compared to 36.3% of men and 68.2% of women aged 75 and older. Distal interphalangeal joints were more often involved (22.8% of men and 37.9% of women) than the proximal ones (9.7% of men and 19.6% of women). The factors most closely associated with osteoarthrosis were age and body weight. Occupational work load, as classified in this study, was not significantly related to the development of osteoarthrosis, except in the group of housewives, in whom the prevalence of finger arthrosis was greater than in the other groups of women.

Extrinsic muscles of the hand signal fingertip location more precisely than they signal the angles of individual finger joints.

Studies have demonstrated that muscle spindle organs provide the majority of the proprioceptive information available to the nervous system about limb position. Other studies suggest that a sense of position may be lacking in the fingers, as subjects were unaware of rather large excursions of finger joints if the excursions were made slowly enough. We sought to investigate the basis for this unexpected finding with a biomechanical model of the human long finger and the forearm muscles which actuate it, in order to study potential contributions of spindle organs in the extrinsic muscles of the hand to a sense of position of the finger. The model, based on cadaver data, allowed us to determine how precisely estimates of the lengths of the extrinsic finger muscles can be transformed into estimates of: (1) the flexion/extension angles of the individual finger joints, and (2) the location of the fingertip in the flexion/extension plane. We found that, for some finger positions, length information from all three extrinsic muscles was not sufficient to precisely estimate the flexion angles of all finger joints. Precision of joint angle estimates could be as poor as +/- 18% of joint range of motion. However, length information from just two of the extrinsic muscles taken together could always provide information sufficient to estimate the location of the fingertip relative to the metacarpophalangeal joint within a reasonably small tolerance (+/- one-half thickness of the fingertip). Furthermore, it was possible to make this estimate without determining any of the finger joint angles. These results suggest that spindles in the extrinsic muscles alone can signal fingertip location, even though they may not provide sufficient information to estimate the individual joint angles that set the position of the fingertip. Thus, an absence of position sense for individual joints (the sense many studies have tried to measure) may say little about a sense of location of the tip of the finger.
