[Osseous extensor tendon rupture of the finger joint: surgical technique and results].

Mostly mallet finger can be treated conservatively. In cases of fracture of the distal phalanx open reduction and fixation is recommended. We favour the well-established cerclage, yet perform it in a more comfortable way with the use of cannulated drilling. This technique was applied on 13 patients even with lesions several weeks old. The evaluation 5-16 months postoperatively based on radiological, clinical and subjective criteria. We present the technique and the results followed by the discussion of the advantages over conservative and other operative managements.

Comparing biomechanical investigations about different wiring techniques of finger joint arthrodesis.

INTRODUCTION: Multiple operative techniques are currently used for finger arthrodesis in clinical practice. The present study was designed to compare the biomechanical characteristics of typical arthrodesis techniques used in daily practice. MATERIAL AND METHODS: Osteosynthesis techniques comprising wire cerclage, thread cerclage (PDS) or intraosseous wire suture were compared in a biomechanical experiment for resistance against bending loads. The mentioned techniques were applied to artificial specimens with resected articular surfaces or by using the cup-and-cone procedure. In this process, the specimens were tested using various Kirschner-wire insertion angles as well as different arthrodesis angles (20 degrees vs 40 degrees) in a 4-point bending test with each group consisting of 6 specimens of acrylic glass. The forces prevalent in the joint space were determined by prescale pressure measurement foils. RESULTS: Wire tension banding resisted significantly higher bending moments than arthrodeses with thread tension bands (p < 0.05). All set-ups with tension banding techniques tolerated significantly higher loads than the intraosseous wire sutures without additional K-wires (p < 0.05), which showed unfavorable dislocation of contact areas resulting in instability even under relatively minor bending loads. Using the cup-and-cone technique, a geometrically larger contact area could be achieved between two unloaded fragments, but this technique showed no advantages in the opposing bending moments compared with the conventional resection method. In both techniques, a dislocation of contact surfaces towards the palmar direction could be observed with increasing bending moment. While the use of thread tension band fixation reduces the risk of plastic deformation of both osteosynthetic material and bone stock, the problem of resorption rate has to be taken into account when choosing the material for the thread. CONCLUSIONS: Considering pressure distribution and stability with and without bending loads, it is not the most rigid osteosynthesis technique which should be viewed as the ideal treatment. In contrast, it is more important to consider the various and most likely conditions to be expected in daily life after arthrodesis and therefore to chose the type of technique distributing pressure as regularly as possible.

[Quality control of prosthetic replacements of knee, ankle, toe, shoulder, elbow and finger joints in Norway 1994. A report after the first year of registration of joint prostheses in the national registry].

Total hip replacements have been recorded in the Norwegian Arthroplasty Register since 1987, and recording of the other joint arthroplasties was started in January 1994. After 12 months 1,589 primary arthroplasties had been registered; these referred to 962 knees, 11 ankles, 76 toes, 113 shoulders, 69 elbows, 12 wrists, 335 fingers and 11 carpometacarpal 1 joints. Median age of the patients was 70 years. 80% were women. Rheumatoid arthritis was the predominant reason for joint replacement, except in the case of the knees where the dominant cause was osteoarthrosis (71%) and of shoulders, 28% of which were replaced because of fractures. Cement was used in 83% of the primary arthroplasties in knee, ankle, shoulder, and elbow joints. 74% of the cement types used contained antibiotics. 9% were uncemented and 8% hybrids. 97% were given systemic antibiotic prophylaxis, most commonly first generation cephalosporins. 114 reoperations were reported. The reason was aseptic loosening in 56%, and infection in 15%. The cooperation with Norwegian orthopaedic surgeons is good. The Register thus provides a reliable picture of implants of Norway, and a good basis for future follow-up studies.

Post-traumatic distal interphalangeal finger joint reconstruction using a free hemi-joint transfer from the fifth toe middle phalanx.

We present three cases of finger distal interphalangeal joint reconstruction in children using a new donor site, the middle phalanx of the fifth toe, transferred as a non-vascularized graft. The patients were followed a minimum of 36 months with serial radiographs, magnetic resonance imaging and photographs. Alignment was improved and persisting growth was demonstrated in all cases. Postoperative magnetic resonance imaging of the grafted phalanx and control toe showed comparable signals. The absence of a proximal epiphysis of these toe phalanges may have an important role in their survival after free transplantation, and may promote continued growth.
