Rupture of the flexor tendons of the little finger in fractures of the hook of the hamate bone. Report of two cases.

Two cases of rupture of the flexor tendons of the little finger associated with a fracture of the hook of the hamate bone are presented. The preoperative diagnosis had not been made. Excision of the fractured hook and repair of the tendons by a short graft from the palmaris longus in one case and by the transfer of the superficial flexor of the ring finger in the other case gave a good final result. The authors remark on the rarity of reports of this fracture in the literature, the frequent occurrence of nonunion and the two complications which are exceptional; rupture of the flexor tendons and compression of the deep branch of the ulnar nerve. The fracture is mainly encountered in sports that require the grasping of a handle (tennis, golf, hockey, squash). The diagnosis is often missed at the onset because of not using the correct X-ray positioning: special incidence for the carpal tunnel view and a 3/4 view with the wrist in 45 degrees of supination and forced radial deviation.

Simple arthrolysis for flexor rigidity of the proximal interphalangeal joint.

The authors report 19 cases of simple arthrolysis of the proximal interphalangeal joint for flexion rigidity. Their cases were limited to isolated lesions of the joint without any flexor or extensor tendon involvement. The technique is described, and the importance of postoperative physical therapy is stressed. The results in these cases, in contrast with those in complicated cases of rigidity, are very satisfactory. The etiology is primarily sprains and dislocations of the proximal interphalangeal articulation, immobilized for too long a time in flexion (in the so-called "functional position").

Two-step reconstruction of the flexor tendons (Hunter's technique) in the treatment of fingers "en crochet".

The authors used Hunter's technique to treat 16 cases of fixed-flexion deformity of the finger (with irreducible flexion of the joint greater then 70 degrees), secondary to lesions of the flexor tendons. The flexion deformity was corrected in 11 of the 16 cases, and active movement greater than 70 degrees was obtained in only 7 cases. Technical difficulties (particularly cutaneous problems), frequent complications, prolonged reeducation are the reasons that the indications for its use are exceptional, and why there is need for excellent cooperation by the patient.

[Carpal tunnel syndrome in chronic hemodialysis patients. An etiopathogenetic approach. Apropos of 31 surgically-treated cases].

Thirty-one carpal tunnel syndromes were seen in 20 patients treated by haemodialysis for renal failure. At the time of operation, the duration of the haemodialysis was an average of 9 years. On 24 occasions, the syndrome existed in the limb of the arterio venous fistula but on 7 occasions it only appeared in the opposite limb. The syndrome is characterised by the development of, or the worsening of paraesthesiae during haemodialysis sessions. The degree and duration of the numbness in the fingers in the morning was particularly striking. At surgery, the nerve was always obviously narrowed. It was noted in 21 cases that there were greyish granulation in the synovium and sometimes intra tendinous nodules. All the operated cases improved. The pathogenesis is discussed in relation to amyloid deposits. The haemodynamic role of the fistula seems to be to make the development of the lesion more likely. Microscopic examination and biochemical studies give rise to the conclusion that this is an AL type of amyloidosis.

Osseous metastases in the hand. A general review of three cases.

Osseous metastases in the hand are rare. The authors report 3 cases, bringing the total number of reported cases up to 106. They affect mainly men; their clinical features are local swelling and pain frequently ascribed to a trauma. The diagnosis is often mistaken, many patients being initially treated for a distal felon. Distal phalanx is the main involved area, with irregular osteolysis and cortical destruction. The etiology is quite different from that of metastases to other bones: bronchopulmonary cancer is by far the most frequent with 46% of cases, followed by breast cancer (15%). Other types of cancer are much less frequently involved. The evolution is sombre; average life expectancy is 3 1/2 months. Treatment may involve, as needed, distal digital amputation on antalgic radiotherapy.

First results of arthroplasty of the wrist by Swanson's implant. Twenty-five cases.

We have carried out 25 arthroplasties of the wrist using the Swanson implant since 1976. The indications were primarily in rheumatoid arthritis. The operation was done for severe pain and deformity of the wrist. Results were analysed in 19 patients with a follow-up of 21-54 months. Post-operative pain relief is good. Although mobility is fair, the return of the balance of wrist motions has been recovered. The results of the Swanson implant arthroplasty are compared to dorsal synovectomy and wrist arthrodesis.
