Tension-band arthrodesis in the finger joints.

Tension-band arthrodesis was employed in 26 finger joints with various pathological lesions. This is a simple procedure based on the principles of compression osteosynthesis. Stability thus achieved makes immobilization of the hand unnecessary and allows full motion of all adjacent joints.

[History of arthroplasty for finger joints].

The history of joint prostheses does not begin before the end of the 19th century. Prior to that, resection arthroplasty of functionally impaired joints was attempted with results sometimes allowing flexion or straightening of a previously immobile joint. These operative methods developed into interposition arthroplasty, which in its turn represents the predecessor of joint implantation. Lower extremity joint implantation is nowadays a well established and rewarding strong hold of orthopaedic and trauma surgeons. Due to certain obstacles specific to the hand, a similar success story for prostheses of the finger joints is still awaited. Although there have been many different designs of finger joint prostheses over the last 50 years, there is still no implant which offers satisfactory and reliable long-term results such as those that we have become accustomed to expect from lower extremity joint allo-arthroplasty. Only recently are we able to speak of an acknowledged standard of PIP-joint allo-arthroplasty. Using the library of the German historical museum of orthopaedic surgery as well as the relevant sources of international medical literature, a survey of the development of finger joint implantation is made.

[Intra-articular therapy with superoxide dismutase (orgotein) or cortisone in rheumatoid and arthritic inflammatory finger joint lesions].

The use of intra-articular corticosteroid therapy during the acute stage of arthritis is widely accepted. The symmetric involvement in both hands of identical finger joints is the ideal basis for a comparative study of the efficiency of such injections. In a randomized trial corticoid was directly compared with Orgotein, the enzyme "Superoxid-Dismutase" which inactivates oxygen-combinations and thereby interrupts inflammatory reactions. In this way accepted treatment of both sides was possible without the use of a placebo which could be considered as doubtful for ethical reasons. The results were evaluated using the following three reproducible parameters: 1. joint diameter before and after treatment 2. strength of pinch-grip 3. range of motion. Thirty-one patients with ninety-eight affected joints were treated and followed up. Thirty patients showed an improvement upon both treatments. Twenty-six of them reported identical pain relief for the corticoid and Orgotein treated joint on both sides after approximately three injections per finger joint. In four cases pain relief in the Orgotein treated joints was less significant than in the corticoid treated ones.

[Results of alloarthroplasty in finger joints damaged through injury].

Follow-up examination is reported of 24 patients with post-traumatic arthritis treated by 29 finger joint implants. The average follow-up time was 35 months. It could be shown that implant arthroplasty in painful, unstable finger joints stiffened in an unfavourable position represents a quite reasonable method of treatment. Necessary essentials, however, are sufficient function of the tendons, skin areas without twoo extensive cicatrical changes, precise operative procedure and adequate postoperative treatment.

[Reproducibility of measuring the finger joint angle with a sensory glove].

Joint angles are measured using goniometers according to the neutral-zero method. These measurements are dependent on the examiner and are thus subject to great variation. With a newly developed sensor glove, the grip patterns of the hand can be captured with a computer-assisted technique. In a comparative study involving five subjects, the joint angles during power grip around a cylindrical body and while clenching a fist were determined by nine examiners at three different times, using the conventional technique according to the neutral-zero method. In the same experimental design, the joint angles were measured with the sensor glove. As a criterion for the reproducibility of the measurements, the intraclass correlation coefficient (ICC) was calculated by means of an analysis of variance. The ICC is a value which approximates 1 if the reliability of the measurements is high. At 0.94, the ICC of the data determined with the sensor glove was markedly higher than the mean ICC for all examiners of 0.50 using the conventional method. Besides the measurement of the finger joint angles, the sensor glove allows the dynamic recording of joint movements of all finger joints during different grip patterns of the hand.

[Ultrasound diagnosis of hand and finger joints. Changes in arthritis].

Arthritis of the hand and finger joints is seen with unspecific and specific signs, as known from the hip and knee joints. The examination has to be done with special applicators (small sized with 7-13 MHz). Especially signs such as erosions and surrounding synovitis ensure the diagnosis of rheumatoid arthritis.

Treatment of finger joints with local steroids. A double-blind study.

The study was performed in 24 patients all having rheumatoid arthritis affecting the finger joints. Randomly, and in a double-blind fashion, the inflamed interphalangeal and proximal interphalangeal joints of one hand were injected with either triamcinolone hexacetoide (TH) or methylprednisolone (MP) and those of the other hand vice versa. A total of 120 affected swollen finger joints were injected--59 joints with TH and 61 with MP. The duration of effect and the possible side effects were followed up for a period of 6 months. All injections produced clinically significant effects. There were no significant differences between the two treatment groups at the start of the treatment, but after 6 months the results in the TH group were significantly better. However, there were also more joints with skin and soft tissue atrophy in this group than in the MP group.

Silicone lymphadenopathy and synovitis. Complications of silicone elastomer finger joint prostheses.

We report two complications of silicone elastomer finger joint prostheses. In one patient, the prostheses broke, with silicone particles present in synovium ("detritic synovitis"). In another patient, silicone particles were found in an axillary lymph node five years after insertion of prostheses in the ipsilateral hand (prostheses were intact at the time). Microscopically, silicone particles in synovium and lymph node were identical to particles abraded from a new prosthesis.

[The development of a finger joint phantom for the optical simulation of early inflammatory rheumatic changes].

In the field of rheumatology, conventional diagnostic methods permit the detection only of advanced stages of the disease, which is at odds with the current clinical demand for the early diagnosis of inflammatory rheumatic diseases. Prompted by current needs, we developed a finger joint phantom that enables the optical and geometrical simulation of an early stage of rheumatoid arthritis (RA). The results presented here form the experimental basis for an evaluation of new RA diagnostic systems based on near infrared light. The early stage of RA is characterised mainly by a vigorous proliferation of the synovial membrane and clouding of the synovial fluid. Using a double-integrating-sphere technique, the absorption and scattering coefficients (mua, mus') are experimentally determined for healthy and pathologically altered synovial fluid and capsule tissue. Using a variable mixture of Intralipid Indian ink and water as a scattering/absorption medium, the optical properties of skin, synovial fluid or capsule can be selected individually. Since the optical and geometrical properties of bone tissue remain constant in early-stage RA, a solid material is used for its simulation. Using the finger joint phantom described herein, the optical properties of joint regions can be adjusted specifically, enabling an evaluation of their effects on an optical signal--for example, during fluorography--and the investigation of these effects for diagnostically useful information. The experimental foundation for the development of a new optical system for the early diagnosis of RA has now been laid.
