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.

Pedicle graft epiphysis transplantation.

Transfer of a graft taken from the iliac crest apophysis of 48 immature dogs was studied as a means of repairing an epiphysiodesis constituting more than 50% of the growth plate area. Four groups of dogs were studied. In Group I the graft was pedicled on the superficial circumflex iliac vessels and reimplanted in situ. In Group II the pedicled graft was transferred to the groin area as an island graft. These two control groups demonstrate the conservation of growth activity when the graft is pedicled on its epiphyseal vessels. In Group III the graft was transferred to the distal epiphyseal area of the femur after resection of the portion of the growth plate (approximately 2/3) located inside the perichondrial ring, with conservation of 80% of the outer portion of the cylinder. Microsurgical revascularization was achieved by using the saphenous vessels. In Group IV (the control group for Group III) the latter technique was used without revascularization. Roentgenography was performed for nine months after operation. The specimens were studied by tetracycline labeling and histologic and histochemical examinations. Results indicate that a well vascularized graft functions as a dynamic catalyst for regeneration of the resected portion of the growth plate and prevents the formation of bony bridges between the epiphysis and metaphysis by possible activation of the peripheral groove of Ranvier.

[Sleep and dreams in patients with parietal and frontal lobe lesions].

Polygraphic recordings, psychological tests, and analyses of dreams during paradoxical sleep were conducted in 9 patients with parietal lobe, in 7 with frontal lobe lesions and in a control group. No significant differences in sleep organization were observed in the parietal group, but there was a considerable reduction in oneiric activity and alterations in results of some psychological tests. Several correlations based on statistical data are discussed. Oneiric activity was disorganized to a much lesser degree in patients with frontal lesions.

Toe transfers for congenital hand defects.

From 1977 to 1980, 21 second toes were transferred with microvascular anastomoses for congenital hand defects in 17 patients. There have been no vascular failures. Four thumbs were reconstructed with very good functional and cosmetic results. Active motion of the transplanted toe is limited, and the functional results depend on the mobility and musculature of the metacarpal remnant. Growth has been continuous and at least equal to the other toe. Cosmetic results have been very good. It is essential to distinguish between patients showing aplasia and those presenting amniotic band "amputation" syndrome. In the latter case, all structures are close to normal and the results are therefore better. Operative indications must be carefully appraised. If surgical intervention is decided upon, the ideal age is about 18 months, at which time the best integration of the toe is observed.

Self-regulation of chronic arthritic pain and long-term analgesic dependence in a haemophiliac.

Haemophilia is characterized by recurrent internal bleeding episodes, with repeated haemorrhages into the joint areas eventually resulting in a chronic condition similar to osteoarthritis. A 31-year-old haemophiliac, with a nine-year history of narcotic analgesic dependence secondary to chronic arthritis pain, learned self-regulation techniques consisting of progressive muscle relaxation exercises, meditative breathing, and guided imagery. Long-term follow-up evidenced clinically significant decreases in arthritic pain intensity and analgesic intake subsequent to self-regulation training.

The free scapular flap.

The scapular flap is described, based on the posterior cutaneous branch of the inferior scapular artery. This flap has been successfully used in four clinical cases. The advantages of this flap lie mostly in its large, long, and very dependable vascular pedicle. It can be taken with the patient on his side or prone. The skin is thin and does not need defatting. The main disadvantage is the scar, which is on the posterior aspect of the scapula. This flap is very useful in the treatment of small defects of the ankle or lower leg.

[Epiphyseal vascularization during growth. Study preliminary to transplantation].

A study was conducted of 50 cadavers in children and 25 immature dogs to discover more precisely the vascularization of the lower end of the femur and the iliac crest. It was concluded that it is possible to transplant these epiphyses with anastomosis of three pedicles in the same line. It was also concluded that the vascularisation differs before and after the formation of the bony epiphyseal nucleus. The cartilaginous canals which preclude the vascularisation of hyaline cartilage, the formation of the bony nucleus and the nutrition of the germinal layers of the growth plate are described.
