[Traumatic pseudo-boutonniere of the metacarpophalangeal joint of the little finger. Case report and review of the literature].

Dislocation of the extensor tendon over the metacarpophalangeal joint is common among patients with rheumatoid arthritis. Patients without arthritis are exceptionally involved. The authors describe a new case of traumatic boutonniere-like of the metacarpophalangeal joint of the little finger. This lesion is a rarely, only eleven cases are described in literature. Patients are usually young adults and dislocation is related to a direct axial trauma on their fifth metacarpophalangeal joint. Diagnosis is clinical and relies on an incomplete active extension of the metacarpophalangeal joint, secondary to the dislocation of the extensor apparatus. Diagnosis is often delayed the lesion remaining unnoticed with the occurrence of others hand lesions. Proper treatment is surgery, based on suturing side to side both extensor digiti minimi and common extensor tendon over the fifth metacarpophalangeal joint. Results are excellent, with a complete range of motion and the absence of recurrence.

[Heterotopic digital transplantation in an 80-year-old man].

The authors report a case of amputation of the first, second and third fingers of the left hand in an 80-year old man. As the thumb was not replantable, a pollicization by hetero-replantation of the index was performed as an emergency. With a 1-year follow-up, the functional result was satisfactory. Analysis of the case report again shows that in the case of thumb amputation, hetero-replantation according to the principles of "finger-bank" is the solution of choice and demonstrates its feasibility in the elderly. The authors discuss the recovery of sensation.

[Cutaneous hemangioma associated with eosinophilia].

A patient with a cutaneous angioma developed an intravascular coagulation syndrome with a eosinophilic leukocytosis and multiple arterial and venous thromboses affecting the vital prognosis. The possible role of the eosinophilia in the mechanism of complications is discussed. Local modifications in the angioma are suggestive signs preceding the onset of general thrombotic complications, their severity contrasting with the simplicity of the secondary surgical excision of the angioma.

[The axial orientation of the phalanges following the curling up of the fingers].

This study follows and modestly completes those by Dubousset and Kapandji concerning the phenomena of axial (or longitudinal) rotation of the phalanges combined with flexion-extension of the fingers. Our analysis of the orientation of axial rotation of the skeletal elements of the digital chain, in relation to each other and during digito-palmar flexion was supported by simple observation, impressions in silicone paste, study of anatomical preparations, three-dimensional computed tomography. The index finger and middle finger tend to supinate. The ring finger undergoes virtually no rotation and the distal end of the little finger tends to pronate. These phenomena, essential for good adaptation to grip and fine manipulation must be taken into account by rehabilitation physicians when the amplitude of these movements are limited by immobilisation or disease.

[Venous drainage of Littler's neurovascular pedicle flap].

The antegrade transosseous injection of the digital veins, followed by dissection enables the authors to analyse the role of various networks in drainage of the pulp. The satellite veins of the digital artery in the finger are probably not involved. The venous return of the pulp is constituted by an anatomical continuity between the superficial palmar network and the common digital veins. A narrow anastomotic channel is demonstrated in the commissure between these two systems.

[Poncet-Spiegler cylindroma. Apropos of a recent case].

The authors describe a new case of multiple cutaneous cylindromas (Poncet-Spiegler cylindroma), and discuss the clinical and histopathological characteristics of this rare affection. Treatment is exclusively surgical, with plastic surgery being required for advanced cases. In the case presented, a free flap from the forearm was used to cover the area of extensive loss of cutaneous matter in the parotid region.

Systemization of the vascularization of the ulnar nerve in its upper arm.

Vascularized free nerve grafts make possible the repair of extensive defects of large nerve trunks. Since the original observations of Taylor and Ham in 1976 many cases have been published. The ulnar nerve in the upper arm in most cases has a simple arteriovenous pedicle the anatomy of which has been precisely defined by cadaver dissections and intravascular injections. The arterial supply, 47 times out of 50, is the proximal ulnar collateral and 2 times the distal collateral ulnar artery. It takes its origin from the medial side of the brachial artery in the upper or middle third of the arm. Its external diameter is on the average 1.8 mm at its origin. The accompanying vein enters a brachial vein 2 to 3 cm below the origin of the artery. The removal of the graft is done through a straight incision on the inner aspect of the arm. The brachial artery is dissected from above downward and its medial branches noted. The nerve and its arteriovenous pedicle are separated in a block along with adjacent cellular tissue by dissection from below upwards. The average length of the pedicle thus produced is 13 cm, but a much longer section of the nerve can certainly be taken. A case report illustrates the procedure.

[Vascularization of the ulnar nerve of the arm].

A review of 53 dissections associated with injections and radiographs was performed (by the authors) to specify the arteriovenous vascularization of the ulnar nerve of the arm. An arteriovenous pedicle is constantly to be found. The artery "collateralis ulnaris superior" arises from the inferior border of the "pectoralis major" at an average distance of 6,7 cm. The arterial depending vein most often directly rejoins the "vena brachialis" lower than "vena basilica" does, but usually more distally than the arterial emergence level. Thus constituted, the pedicle can be anastomosed, measuring generally more than 1 mm in diameter. The arterial distribution originates from an arcade parallel to the nerve from which arise some extremely fine ladderlike vessels. Finally, this pedicle vascularizes the whole brachial part of the nerve (roughly 23,6 cm).

[Technic of continuous axillary plexus block].

A technique of continuous axillary brachial plexus block, using an epidural Tuohy needle and an epidural catheter, is described. Studies were carried out in ten patients using this technique with bupivacaine as a local anesthetic drug. The catheter remained indwelling during a mean period of five days. Good analgesia was obtained in nine out of the ten patients. Thus this technique allows pain-free postoperative period in hand surgery.
