Anatomic basis for the construction of a musculotendinous flap derived from the pectoralis major muscle.

The vascularization, innervation and termination of the clavicular portion of the pectoralis major muscle were studied by dissection of 7 adult subjects and 2 fetuses. The vascular and nervous autonomy of the clavicular portion was confirmed. Blood-supply was effected by 2 arteries and innervation by an independent nerve. The exact distribution of the fibers composing the pectoralis major and their complex insertion are described. It is concluded that the clavicular portion can be employed as an active muscle transplant to the head of the humerus when the short rotator muscles of the shoulder are ineffective.

Chondromas of the hand. A report of thirty-five cases.

Twenty-nine patients were treated in the department of orthopedic surgery of Purpan (Toulouse), with thirty-five chondromata of the hand. Follow-up was over one year. Chondroma is a bone tumor predominantly of the left side, second ray of the hand and phalanx. Some multifocal cases have been observed. The diagnosis was made in half the cases through a pathological fracture. Chondroma is characterized by a diaphyseal or a metaphyso-diaphyseal lacuna, wearing away the cortical bone. Treatment consisted of curetting the tumor and filling the cavity with iliac cancellous bone graft. The clinical result was been excellent in 15 cases (60%), good in 6 cases (25%), with only some residual pain, and/or digital swelling. In two cases the finger was stiff, but functionally not disabling. In one case the stiffness was important and very disabling; after several recurrences it evolved into a chondrosarcoma.

Radio-carpal and inter-carpal degenerative arthritis in sequellae of scaphoid injuries.

Degenerative arthritis is a frequent pattern after old fractures or rotatory subluxations of the scaphoid. The authors have studied this phenomenon, on 48 wrists. In old scaphoid fractures, the degenerative arthritis begins with an impingement between radial styloid process and proximal pole of the scaphoid, and then reaches the lunocapitate joint. A dorsi flexion by instability is then constant. After a scaphoid subluxation, degenerative arthritis begins between scaphoid and radial epiphysis too, but arthritis in these cases, is earlier and more symptomatic. We found two types of wrists: the sequellae of the post-traumatic scapholunate diastasis and the peri-scaphoid arthritis "primary in appearance", which corresponds to the scapholunate advanced collapsed pattern of A.K. Watson.

An experimental study of partial intercarpal arthrodesis.

In this experimental study the authors show that partial intercarpal fusions performed on the first carpal row, and not involving the mediocarpal joint, only very slightly limit the mobility of carpal movements: particularly dorsal flexion and radial deviation. Thirty intercarpal fusions were performed with 15 wrists from embalmed cadavers using staples. The range of motions was measured on roentgenograms before and after stapling. The loss of motion was calculated for each type of "partial intercarpal fusion". We present the results with the average loss of motion in percentage and we discuss the indications of these intercarpal fusions, giving for each one the biomechanical explanation of the effects of these intercarpal fusions.

Traumatic avulsion of the flexor digitorum profundus tendon. Report of nineteen cases.

Avulsion of the profundus tendon of the fingers is a rare lesion. This injury is seen mainly in rugby players and involves more commonly the fourth finger. Nineteen patients are reported in this series which was divided into recent avulsions (6 cases), old avulsions (8 cases) or sequelae of initial ill-founded treatment (5 cases). The importance of proximal retraction, the delay before diagnosis and the involvement of the long vinculum provide the basis for a classification into three types. Treatment consists of distal reinsertion with a "pull out" technique, resection of the profundus tendon or tendon grafting.

Glomus tumors of the hand. Presentation of fourteen cases.

The authors report a series of fourteen patients with a glomus tumor in the hand. The major symptoms were excruciating spontaneous pain upon mechanical and thermal stimulation of the tumor. In subungual tumors, a blue discoloration is suggestive of diagnosis; but this was found in only 50 percent of cases. The difficult in correct diagnosis and therefore for complete removal is due to in the location of the tumor. Recurrence may occur in cases of incompletely removed tumor. In three cases, the tumor was submitted to electron microscopic examination which led to a better comprehension of the histogenesis of these tumors.

Measurement of plasma levels of clomipramine in the treatment of chronic pain.

The analgesic effect of clomipramine and the possible relationships between the antalgic action and the plasma levels of this tricyclic drug have been studied in 30 patients with chronic pain induced by nervous lesions determining a deafferentation. Twenty of 30 patients treated with clomipramine reported a significant improvement (up to 50%) observed as soon as the 4th day, with few side effects. The pharmacokinetic analysis shows the existence (r = 0.358; p less than 0.001) of a relationship between analgesia and plasma levels of clomipramine for each individual patient. This study also indicates a "therapeutic window" of plasma levels between 20 and 85 ng/ml. These results permit discussion of measurement of plasma levels of clomipramine in the treatment of chronic pain.

[Late ulnar paralysis. Study of a series of 17 cases].

Seventeen cases of late ulnar paralysis treated by neurolysis-transposition are reported. The clinical characteristics of these paralyses are emphasized: very prolonged symptom free interval, rapid onset and severe involvement. Ulnar transposition was most often done subcutaneously. Cubitus valgus and definite nerve compression proximal to the arcade of the flexor carpi ulnaris muscle are almost always present. The results as regards the neuropathy are undependable: no patient is completely cured and only half are improved. An anatomical study of the nerve path shows the essential role, in the compression of the nerve, of the muscular arcade of the flexor carpi ulnaris muscle which acts in a way similar to the bridge of a violin. Hence, opening it longitudinally is the principal step of neurolysis. This should be routine before the first signs of neuropathy occur in an elbow whose axis is out of alignment as a sequela of a childhood injury.

[Median nerve compression syndrome at the elbow (author's transl)].

Twelve cases of median nerve compression at the elbow are presented. More than half of them showed only an anterior interosseous nerve syndrome (Kiloh-Nevin). Nevertheless, surgical exploration was performed from the brachial tunnel to the superficialis arch. When the neurolysis occurred reasonably early, uniform good results were obtained.
