[Initial results of free bone transposition of the iliac crest in pelvi-mandibulectomy].

Mandibular reconstruction in 6 patients was by free flap from iliac crest in pelvi-mandibulectomies. The different technics proposed for mandibular reconstruction are described with emphasis on the specificity of repair surgery in cervicofacial oncology. In this precise indication stress is placed on the limitations of conventional graft and endoprosthesis procedures and the need to transfer a vascularized bone fragment. Among the technics for transfer of vascularized bone, preference is accorded to the composite flap from iliac crest as against the osteo-musculo-cutaneous flap, and details for removal of the former are given. The osteo-musculo-cutaneous flap from iliac crest appears to be the procedure of choice for reconstruction of bone in all cases where mandibular reconstruction is necessary after loss of continuity.

Analysis of sequelae secondary to the radial forearm flap. A study of twenty-six cases.

The radial forearm flap is used extensively in hand and reconstructive surgery. We have performed 31 radial forearm flaps (15 free and 16 pedicled flaps) in 25 adults and 5 children. This series was analyzed in an attempt to minimize the sequelae of the upper limb and provide more specific indications for this flap. Vascular sequelae were assessed by Doppler and thermography examinations. The functional sequelae were appreciated by wrist motion and grasp strength examinations. Cutaneous sequelae were evaluated according to the time of healing and the quality of the scars. Several technical modifications may be proposed in order to try to minimize sequelae. As shown by our study, cutaneous sequelae are the most important and they must always be considered in the indication of this flap.

[Bilateral lunato-triquetral synostosis with bilateral fracture of the scaphoid bone].

The authors have treated a case of bilateral fracture of the scaphoid bone in a young man who had complete and bilateral lunato-triquetral synostosis, without any other associated congenital condition. Consolidation was obtained by orthopedic treatment on one side, but a Matti-Russe operation was necessary on the other. The authors emphasize but then rule out the hypothesis of a congenital bipartite scaphoid associated with the synostosis. A review of the literature on lunato-triquetral synostoses sums up the main points. The condition is rare in whites and occurs more frequently in blacks. It is sometimes associated with other congenital conditions. Four anatomic and radiologic types have been described. The pathogenic hypotheses, based on embryology, are summarized.

[Effects of local corticoids on the nerve fiber. Experimental study (author's transl)].

The intra-operative establishment of some impairments of the median nerve, in patients who are operated for carpal tunnel syndrome and who previously received several local injections of corticoids, led the authors to try to see the respective responsibility of the compression and of the injection in the degenerative process. In 60- dog cubital nerves, it has been possible, to study different parameters by intra and perineural (recurrent or not injections: the puncture, the dilatation, the solvents, the benzylic alcool and two long action corticoids very often used (triamcinolone acetonide, cortivazol). In the first of our series, the injections were done around the nerve and inside the nerve under visual or blind control (as for an infiltration). The nerves are then cut off after 1, 2, or 3 months. In the second of our series, the injections were done in the same way, but recurrently on the first, second and third month, and the nerve was cut off within the fourth month. An electrophysiological study was performed before taking the samples; they were then prepared for reading on the optical and electron microscope. The results show lesions characterized by an epineural spumous sediment, a localized decrease in the large fibers under the perineurium in the first and second series. These impairments seem to be diminishing with time. However when the injections are done recurrently, the lesions are more important, showing a wallerian degeneration and regeneration.

[Compressive pathology of ulnar nerve. Thirty seven cases reported (author's transl)].

The authors have reviewed 37 operated cases of ulnar nerve compression, on the level of the elbow and the wrist, with a minimum follow-up of one year. Traumatic etiologies are more common on these two levels. The authors find 32% of pure entrapment syndromes at the elbow, whereas this phenomenon does not seem to exist at the Guyon's loge. Mac Gowan's classification was used to range the patients in three degrees, according to the importance of the palsy before operation. Surgical treatment was is all cases, at least decompression. At the elbow was added anterior transposition of ulnar nerve beneath epitrochleal muscles or beneath the skin. Considering the results, these lesions are all the more severe, as they are higher (elbow) and more advanced.

Current aspects of tuberculous tenosynovitis. A report of six cases.

Tuberculosis of tendon sheaths of the hand was rare before the advent of antituberculous drugs. It seems now-a-days exceptional, for the published series become more an more uncommon and smaller. Therefore, the diagnosis is often an operative surprise on a patient with a painless, gradually developing tenosynovitis. No patient suffered from other active tuberculosis. But two of them had an old history of tuberculosis (knee and kidney). Analysis of other cases is inconclusive about the relation ship between trauma and tuberculosis. Histology and cultures establish the diagnosis. Surgical treatment consists in large excision of involved tissues. The damages provoked by the illness are often important, with sometimes tendon ruptures. However, functional results are surprisingly not so bad. Antituberculous drugs are the backbone of the surgical treatment for several months.

[Carpal tunnel syndrome].

The authors have reviewed 250 cases of carpal tunnel syndrome operated upon in a series of more than 400 cases. They also describe the results of an experimental study of the effects of locally injected corticosteroids on nervous fibers. Following a brief historical introduction, a detailed anatomical description is provided, with emphasis on congenital variations. The pathological, histological and clinical features of the disease are reviewed in the light of modern concepts of nerve compression. The cases in this series are classified according to their cause, among which idiopathic hypertrophic tenosynovitis was predominant. With regard to treatment, the authors conclude from their experience that repeated local injections of corticosteroids are dangerous, whereas surgical treatment is harmless and can be performed on out-patients under regional anaesthesia.

[Carpal tunnel syndrome: present views on causes and treatment. 250 cases (author's transl)].

The authors review a series of 250 patients with carpal tunnel syndrome who were operated upon and followed up, and report on an experimental study of the effects of local corticosteroid injections on the nervous fiber. Predominant among the various causes of syndrome were the so-called "rheumatic" conditions, chiefly fibrous hypertrophic tenosynovitis. Therapeutic indications and medical and surgical treatments are discussed. The need for limiting local corticosteroid therapy to one single injection is emphasized, together with the safety of surgical incision, which can be performed under nerve block anaesthesia and only requires a one-day stay in hospital.
