[Macrolipodystrophy. The value of soft-tissue radiography].

Macrodystrophia lipomatosa is the hypertrophy of a limb or of a limb-segment due to fatty infiltration. X-ray examination of the soft tissues which reveals the presence of fat, most often allows the easy distinction of this disorder from other causes of localized hypertrophy.

[Growth potential of vascularized epiphyseal bone transplants. Experimental and clinical study].

The objectives of this work were to evaluate, in the light of experimental results, the growth potential of vascularized fertile epiphyseal bone transplants transferred with their surrounding soft tissues in children. Thirty-one toe transfers were available for analysis from the series performed in Trousseau hospital (Paris). The results were reviewed with the unique goal of the study of growth. Transferred toes grow in an almost identical fashion to normal toes. The slightly diminished growth difference found was in accordance with experimental results. Criteria for determining the growth of these transfers must be very strict from a clinical as well as from a radiological point of view. The possibility of transfer of an isolated epiphyseal growth cartilage implies previous elaborate studies of the anatomy of epiphyseal vascularity as well as the physiology of intraosseous blood flow. Restoration of this potential for growth in children should be attempted as early as possible.

The posterior arm free flap.

A new cutaneous free flap is described on the posterior side of the arm. This flap is supplied by an unnamed artery from the humeral artery or the deep humeral artery. It is drained by the accompanying venae comitantes. Its nerve supply is from the radial nerve. Its advantage is a flexible skin and a primary closure of the donor site if the flap does not exceed 7 cm in width. The principal disadvantage is its modest measurements. This flap has been employed in five cases for reconstruction of hand and foot. All flaps survived despite a necessary revision of an arterial anastomosis in one case and a partial necrosis in another case. Results are satisfactory, especially in restoration of weight-bearing areas of the foot.

Reconstruction of congenital hand defects with microvascular toe transfers.

From 1977 through 1984, the author transferred 49 toes in 38 patients to treat congenital defects of the hand. Eleven patients had successful transfer of two toes from different feet, with a six-month interval between operations. There was one failure in a 16-month-old infant with finger aplasia. On the basis of this experience, the author has refined his indications and timing, which are as precise and well defined as the technique.

[Recent injuries of finger flexor tendons in children].

Fifty children had been treated for recent injuries to the flexor tendons. In them, 98 lesions, of which half were at the palm or the wrist and the other half in areas I or II of the fingers. All the divided tendons were primarily repaired, using a combination of a frame suture and two casting sutures. The results seemed to be better when post-operative mobilisation using Kleinert's technique was used. The overall results were better than those obtained in adults. The indications for secondary tenolysis were infrequent when primary suture was correctly made and spontaneous improvement was noted for up to a year.

Transfer of the abductor digiti minimi (quinti) in radial deformities of the hand in children.

The abductor digit minimi (quinti) transfer is an opposition plasty which is rarely used because of the large armamentarium of other possible transfers. However, it is a very good technic to use in radial side dysplasia in children, especially in the case of four-fingered hands in which it can improve the results of pollicisation. A series of 14 cases with 13 "good" or "very good" results is presented. An anatomical study has defined the distal insertion, distinct from that of the flexor digiti quinti brevis, the vascularisation (Mathes's type II) and the innervation of the muscle. The division of the muscle from the pisiform bone is not recommended because of the risk of pedicular injury.

Epiphyseal vascularization during growth: the upper limb.

Sixty fetal, newborn and child cadavers were injected with India ink and plastic material (Batson's technique) via the subclavian artery. The arterial and capillary intracartilaginous and intraosseous networks of the physes of the long bones of the upper limb were then studied by microdissection of the vascular sources and serial epiphyseal sections in different planes. Already present in the third week of fetal life and present all during the rest of life, this circulation plays a fundamental role not only in the ossification of the epiphyseal cartilage but also in the trophicity of the bone that supports the cartilaginous articular surfaces. Like those of the lower limb, the epiphyses of the upper limb present a typical vascular pattern consisting of three entries, with the exception however of the inferior extremity of the ulna.

Calcification associated with terminal defects of the upper extremity.

Four children who had calcifications associated with terminal defects of the upper extremity are reported. A review of the literature has revealed no previous report. Moreover, an examination of the radiographs of 65 children who had terminal defects of the upper limb failed to show any such calcifications. The exact cause of this association remains unknown.

Tracheal sleeve pneumonectomy for carcinomas of the proximal left main bronchus.

Although most primary cancers of the left main bronchus extending to the carina are inoperable, some patients with such a tumour may benefit from an extended, curative surgical procedure. This type of resection presents specific problems in reconstruction and physiologic management during operation. Between 1977 and 1983, five such patients were managed by left pneumonectomy followed by resection of the carina. They ranged in age from 49 to 65 years. None were irradiated before the procedure. In all cases, an end-to-end anastomosis was made between the right main bronchus and the mediastinal trachea. The high-flow catheter technique was used for ventilation during reconstruction. There were no operative deaths. Excessive bronchorrhea was noted in all patients and was aggravated by left recurrent nerve palsy in two. This report indicates that modern techniques of tracheobronchial reconstruction can be successfully applied in patients with locally advanced carcinoma of the proximal left main bronchus. This type of resection may be the treatment of choice in selected cases.
