[Experimental carpal displacement induced by bony lesions].

Bony lesions were created experimentally in 48 fresh cadaver wrists. They consisted of radial and scaphoid resections along the extent of the proximal carpal row, representative of clinically-induced (usually traumatic) lesions. The displacements obtained experimentally to mirror each clinical situation modify the physiologic equilibrium established between the trans-osseous forces and the ligaments. The comparison between the experimentally-induced lesions and clinical displacements shows the etiology of the clinical conditions which indicates the proper treatment.

[Reduction mammoplasty with a J-shaped scar (the Jean-Sauveur Elbaz technic). Review of 125 cases].

Public hospital experience of reduction mammaplasties using L scars of J.S. Elbaz technique. The authors review their public hospital experience of reduction mammaplasties using the L technique described by J.S. Elbaz. This technique minimizes scaring because there is non medial horizontal branch. After describing the technique, they analyze the immediate and long-term results. Immediate postoperative course is uneventful: there were no cases of cutaneous or areolar necrosis. The following points are emphasized: residual mammary volume, shape, stability of contour, course of the scar, areolar sensitivity and appearance. The overall results are good. This technique has the same advantages as more recent mammaplasty procedures (vascular safety, easily adaptable reduction, good long-term results), for minimal scarring which is an indisputable psychological and aesthetic advantage. Nevertheless, problems arise in cases of very severe hypertrophy, for which secondary procedures are frequently necessary.

[Cutaneous expansion in burns sequelae].

This technique of skin expansion with inflatable balloons has rapidly become generally used since Neuman's and Radovan's work. It offers new prospects for the treatment of the sequellae of burns as it allows increasing the surfaces of the remaining unaffected skin and using them to cover the excision of scar lesions by local or remote flaps. Experience with more than 500 implanted balloons is assessed, demonstrating very satisfactory general results in spite of a still too high number of complications, which increasingly refined techniques aim at reducing.

The nutrient flap: a new concept of the role of the flap and application to the salvage of arteriosclerotic lower limbs.

The nutrient flap is a new concept of the role of the flap. It has three functions: (1) it provides supplementary blood flow to ischemic zones, (2) it assists venous drainage in regions of venous insufficiency, and (3) it induces the formation of a capillary network. Its skin covering role is only accessory. We have applied this principle to osteitis, pseudoarthrosis, and arteriosclerosis. The nutrient flap constitutes a new type of treatment for stage IV arteriosclerosis of the lower limbs when classical revascularization techniques cannot be performed and when high amputation is indicated. Four clinical cases and the surgical techniques used are described. The flap, usually raised from the latissimus dorsi, is anastomosed to the popliteal artery by means of an inverted saphenous vein graft. It is applied to the distal extremity of the limb after excision of the necrotic tissues. The nutrient flap preserves weight-bearing by maintaining the heel.

Boutonniere deformity in Dupuytren's disease.

The boutonnière deformity in Dupuytren's disease has been found to be due to fibrous contraction of the transverse retinacular ligament which anteriorly displaces the fibres of the extensor apparatus. Complete ablation of this ligament and liberation of the extensor apparatus allows easy extension of the finger when operating on severe cases of Dupuytren's contracture.

[Pseudotumoral chondrocalcinosis and carpal tunnel syndrome. Apropos of a case report].

Review of the literature of chondrocalcinosis and rheumatologic osteoarticular causes of the carpal tunnel syndrome. Presentation of one observation of chondrocalcinosis of the wrist with presence of a pseudotumor, developed in the carpal tunnel and having induced a carpal tunnel syndrome, at first subacute, then particularly painful by direct irritation of the median nerve.

[Chronic internal metacarpophalangeal sprains of the thumb. Anatomo-clinical classification and therapeutic consequences].

In the light of a physiopathological study of severe medial strain of the metacarpophalangeal joint of the thumb in 20 cadaver hands, the authors propose a correlation between anatomical and clinical findings and a classification derived from it: Stage I: rupture of one fascicle of the collateral ligament. Passive valgus mobility of less than 15 degrees. The ruptured ends of the ligament remain in contact. Stage II: rupture of both fascicles of the ligament. Passive valgus and supination mobility of the metacarpophalangeal joint of 20 to 40 degrees. Interposition of the dorsal digital expansion between the ruptured ends of the ligament. Abnormal movements can be corrected by applying tension to the dorsal digital expansion. Stage III: rupture of both fascicles of the collateral ligament and the dorsal digital expansion. Tension from the thenar muscles causes abnormal movement and produces a fixed flexion of the metacarpophalangeal joint with hyperextension of the interphalangeal joint (Z-shaped thumb). From this the authors determine the operative indications and suggest a palliative ligamentoplasty to restore the anatomy as much as possible.

Vascularized bone graft pedicled on the volar carpal artery for non-union of the scaphoid.

A bone graft, taken from the medial part of the radial epiphysis can be pedicled on the radial branch of the volar carpal arch, freed back to its origin. The graft can be transferred into the proximal row of the carpus to fill up a loss of bony substance or to provide vascularised bone. This permits the treatment of chronic pseud-arthrosis of the scaphoid where a Matti-Russe operation has failed. In the first three cases operated upon, favourable results have been obtained.

Treatment of elbow contractures in burns.

Contractures of the elbow after burn injury are frequent and are often connected with other contractions. Surgical correction must take into consideration the topography, the likelihood of possible heterotopic ossification and the condition of the surrounding skin. A study of 66 contractures allowed us to reach the following conclusions: Linear contractures surrounded by normal skin require IC-type local flaps. Widespread contractures can be treated with thoracic flaps if healthy skin remains or else with the 'backwards flap'. Surgery on existing associated heterotopic ossification must be in two stages starting with the cutaneous step.

Recent burns of the hand. Early excision-graft versus conventional treatment. A retrospective study during two years.

Early excision-graft of burned hands seems to have totally superseded the conventional method of progressive detorsion often with late grafting. Does this treatment merit acceptance under these conditions? Do the theoretical advantages of aggressive methods counter-balance the primary difficulty of diagnosing the initial depth of burn? Are these fewer difficulties and risks in early excision-graft than in the slower methods? Can we ascribe the failure of conventional method to a poor technical realisation? Following a short summary of the principles of the two methods, we attempt to answer these questions by a retrospective study comparing identical series of patients. We have begun a prospective randomized trial and present the preliminary results here.

[Experimental study on a plaster cast in fractures of the carpal scaphoid. Clinical deductions].

The displacement of the proximal and distal fragments of fractures of the carpal scaphoid have been studied in fresh cadavers. In 10 subjects, a comparison has been made between a below-elbow plaster, a moulded plaster gauntlet and an above-elbow plaster. The most satisfactory immobilisation has been obtained with a moulded plaster gauntlet incorporating the proximal phalanx of the thumb and leaving the elbow free.

Rebuilding the cervico-mandibular angle--correcting a deformity of neck burns.

Repairing the cervico-mandibular angle following neck burns is a major problem. Several artistic landmarks show its aesthetic importance. From a functional point of view, the authors show the positive consequences of rebuilding using the results from 101 patients with neck burns. In principle, the treatment involves maximal use of healthy skin, and the separate reconstruction of the horizontal and vertical parts of the neck.
