[A single-use vascular clamp. An experimental and clinical study].

Twelve rabbit femoral arteries were clamped for one hour with a TKS2 clamp in order to confirm the atraumatic nature of the Tamai disposable clamp. After 15 or 30 minutes of revascularisation, the arteries were excised and studied by light microscopy and scanning electron microscopy. Temporary dilatation of the artery was observed after removal of the clamp, as the patency test was always positive. Light microscopy revealed parietal flattening without any cellular disorganisation and scanning electron microscopy revealed flattening of the endothelial cells without any tearing. On the basis of these favourable results, combined with the ease of use, we now use the Tamai clamp daily.

[Claw nails. Apropos of 16 cases treated by nail recession flap].

16 patients (75% women) were operated for a claw nail involving one of the three middle fingers. In 14 cases out of 16, a traumatic amputation, treated by directed healing in 60% of cases, was responsible for the deformity. The average loss of bone substance was 49% (range: 0-90%). The average shortening was 5 mm. The loss of substance was repaired by a local flap in 14 cases. Two early recurrences led to one failure and one good result after a second recession flap. One case of arthritis of the distal interphalangeal joint and one case of septic necrosis of the nail bed were also observed. Eleven subjects were reviewed with a mean follow-up of 4 years (1-7 years). The range of movement of the distal interphalangeal joint was always normal. The pinch force and the growth of the nail were normal in 75% of cases. The finger was cumbersome in one half of cases and 60% of patients complained of pain. Recurrences were observed in 50% of cases and the patients were disappointed in 64% of cases. This is a minor operation in terms of vascular elements, but it is associated with a high rate of recurrence and leaves a short finger. Its indications should be limited to losses of bone substance less than 50%.

Tendon transfers for treatment of the paralyzed hand following brachial plexus injury.

The correction of functional deficits of the hand after a brachial plexus lesion is difficult; treatment should be provided by a well-knit team of surgeons and therapists. The patient should be fully aware of the limitations of surgical treatment before surgery, and should be entrusted to the care of a physical therapist during the critical period of nerve regeneration after initial surgical treatment to ensure optimal results. This article presents therapeutic possibilities and discusses specific problems of tendon transfers in brachial plexus palsy.

Hyperostotic macrodactyly.

There is a rare and special type of macrodactyly that is called the hyperostotic variety. This disease occurs later than the classical forms of macrodactyly and shows massive osteocartilaginous deposits around the joints. A new case is reported. The cause of this disease could be previous trauma.

[Miniaturized osteosynthesis of articular fractures of the fingers. Results of a series of 60 cases].

The importance of anatomical reduction of articular fractures and early mobilisation of these severe forms of trauma which frequently damage the extensor apparatus (58% of cases, led us to propose direct miniaturised osteosynthesis as described by the Nancy-Strasbourg team. Of the 1,000 cases of osteosynthesis performed between 1978 and 1985, we selected 12 fractures of the MP joint, 38 fractures of the PIP joint and 10 fractures of the DIP joint, differentiated into 4 stages according to the condition of the skin and tendons and into 9 categories according to the anatomical type and the site of the fracture. Direct osteosynthesis (screw, bolt, pin) was used in every case. The clinical results were evaluated in terms of the Total Active Range of Movements, the local trophic state, the amount of pain and return to work, for each joint. When well conducted and with effective skin cover, this technique allows almost normal reconstruction in simple fractures and is valuable in more complex fractures by preserving sliding of the tendinous apparatus due to early mobilisation.

[Littler's operation (SORL = spiral oblique retinacular ligament) in the treatment of "swan neck"].

The surgical treatment of "swan-neck" deformities secondary to mallet finger using Littler's technique (Spiral Oblique Retinacular Ligament) in a series of 35 cases, led to a complete correction of the PIP joint hyperextension in 95% of the cases and a correction of the DIP joint flexure in 70% of the cases. This active tenodesis restores the physiology of the extension of the PIP and DIP joints as far as the surgical technique has been strictly respected.

Automated photography in microsurgery.

An automated method is proposed for photographing a microsurgical field that avoids missed photographs and time-consuming manipulations. The basic principles applied to microscopic photography are briefly reviewed and instructions are provided for standardized, reproducible, high quality photographs. A limitation at present is that auto-focusing cameras have not yet been adapted for use with surgical microscopes. One type of microscope is discussed and details about the only camera system currently suitable for such a microscope are described.

Out-patient hand surgery. A prospective study of 588 patients.

The results of a prospective study of 588 patients operated on over a period of 4 months were analyzed. Of these patients, 6% only had to be hospitalized. The 555 other patients underwent out-patient surgery, 25% of which were emergencies. Thirty-four % of patients had one or more preexisting serious medical conditions. Ninety-one % underwent regional anesthesia. Complications were rare and did not seem to be preventable by hospitalization. While highlighting the many advantages associated with out-patient surgery, the authors stress the guidelines which must be followed as well as the pitfalls to be avoided in ambulatory surgery of the hand.
