[Organization of microsurgery in France: application of microsurgery in orthopedics].

Microsurgery in France is organized in a relatively large number of centers. More centers would compromise the results achieved especially in replantation. Teaching and training is given in specialised courses and at universities. Indications for microsurgery in orthopaedics and traumatology are widespread. Large replantations may give excellent results but frequent complications have to be kept in mind, which sometimes are live-threatening. Free or composite grafts of skin, toe, muscles, bone and joints with neurovascular peduncle may be taken into consideration.

Ring injury with bilateral rupture of the digital arteries without skin damage.

A particular type of trauma of the ring finger, brought about by a ring, resulted in a subadventitial rupture of the radial digital artery and a complete rupture of the ulnar digital artery, despite the skin remaining intact. The radial digital artery was sutured and the ulnar digital artery was repaired by a vein graft. By the eighth month, the result was satisfactory, with a radial digital artery patent, in spite of a thrombosis of the ulnar digital artery.

Peripheral nerve allografts. I. Distinctive histological features of nerve degeneration and immunological rejection.

Sequential sections were prepared from isografted or allografted sciatic nerves in adult female DBA/2 mice and were compared with the wallerian degeneration in the same inbred strain. Transverse sections were studied by qualitative and quantitative histology. Rejection was manifested by an important infiltration of mononuclear cells, including large pyroninophilic cells, around the grafted nerve, followed by the appearance of irregular infiltrates around the neovessels within the nerve. In parallel, the number of endoneural nuclei increased less rapidly in allografts than in isografts up to day 15 and diminished thereafter, in association with a possible reduction of neural vascularisation.

[Compression of the posterior branch of the radial nerve. An unknown etiology of certain paralysis and certain refractory epicondylalgies].

In certain circumstances, compression of the posterior branch of the radial nerve (posterior interosseous nerve) may be caused either by transverse fibrous bands in front of the articular capsule of the elbow, by the anterior border of the 2nd radial, by Frohse's lugament or by the superficial part of supinator brevis. Such problems may be accentuated by repeated dorsal flexion movements of the wrist, with hyperextension of the elbow and above all in prosupination. Clinically, they may result in either complete paralysis (2 cases), or in a syndrome of refractory epicondylar pain with nerve involvement (4 cases). The approach described by the authors permits complete exploration of all the potential points of compression and good results were obtained in the five patients who underwent surgery.

[Study of the zinc levels in serum and erythrocytes in burn patients (author's transl)].

Following a statistical study of four groups of burned people, determined in function of the UBS coefficient, a curve of blood zinc variations has been drawn:Immediately after burning, blood zinc is low. It rises to normal and then increases above normal. A group of patients (very serious or lethal burns) definitely differs from the others in respect of an important and persistent fall of blood zinc. These blood zinc values suggest a possible need for a zinc supply to this group of patients.

[Fibrous arch of the adductor muscle of the thumb (musculus Adductor pollicis)].

In 8 out of 30 cases we found the fibrous arch of the Adductor pollicis muscle. In 4 cases, the resistant arch is situated between the 2 fasciculi of the Adductor Pollicis and inserted on the upper third of the third metacarpian on its anterior face. Il resists a traction of 500 g.; in 4 other cases, it is less resisting. The connections with the deep cubital vasculo-nervous fasciculus are important, especially the deep branch of the cubital nerve which can be compressed at this level.
