Digitalization of the second finger in type 2 central longitudinal deficiencies (clefting) of the hand.

In central longitudinal deficiency of the hand type 2 (Manske and Halikis), the second finger presents itself anatomically and functionally as a second thumb. It is therefore necessary to undertake digitalization of the index, performed exactly as a reverse pollicization technique, with the same principles: minimum volar scarring and reconstruction of a large first web space without scars at the fold of the commissure. The incision surrounds the second digit at the level of the midproximal phalanx, extends over the dorsal edge of the cleft, and finishes on the radial side of the third finger where the second web space is to be created.

[Surgical treatment for boutonniere deformity of the fingers. Retrospective study of 47 patients].

Disruption or laceration of the central slip of the extensor tendon at the proximal interphalangeal (PIP) joint with volar displacement of the lateral bands can result in the so-called boutonniere deformity which includes loss of extension at the PIP joint and compensatory hyperextension of the distal interphalangeal (DIP) joint. Many procedures has been described in the literature and no standard treatment can be recommended. The authors reports a series of 47 cases of posttraumatic boutonniere deformity.

Comparative study of two series of distally based fasciocutaneous flaps for coverage of the lower one-fourth of the leg, the ankle, and the foot.

Skin defects over the lower one-fourth of the leg and over the foot are difficult to cover. Two types of pedicled fasciocutaneous flaps used to cover such defects were studied: the lateral supramalleolar flap and the distally based sural neurocutaneous flap. The series consisted of 27 and 36 cases, respectively.

Medial plantar flap based distally on the lateral plantar artery to cover a forefoot skin defect.

The authors report a simple, single-step procedure to promote the distal transfer of the instep island flap for coverage of the submetatarsal weight-bearing zone. First described in 1991 by Martin et aI, this procedure remained unknown. As opposed to the medial plantar flap, this technique proposes an instep island flap based on the lateral plantar artery.

Extensor digiti minimi tendon "rerouting" transfer in permanent abduction of the little finger.

Permanent abduction of the little finger is a bothersome deformity which usually occurs in the context of sequelae of ulnar nerve palsy (Wartenberg's sign), but also in rheumatoid arthritis. The authors report an original technique for correction of this deformity. The extensor digiti minimi tendon is sectioned at its distal insertion and transferred in the wrist through the extensor retinaculum.

Contribution of magnetic resonance imaging for the diagnosis of median nerve lesion after endoscopic carpal tunnel release.

Deterioration of pre-existing signs or appearance of a nerve deficit raise difficult problems during the complicated course following endoscopic carpal tunnel release. One possible explanation is transient aggravation of nerve compression by passage of the endoscopy material, but these signs may also be due to incomplete section of the flexor retinaculum or an iatrogenic nerve lesion. Each case raises the problem of surgical revision.

Results of non-operative and operative treatment of humeral shaft fractures. A series of 104 cases.

The aim of this study was to examine the results of different modalities applied in the treatment of 104 fresh diaphyseal fractures of the adult humerus treated in the department between January 1994 and March 1997. These results were classified according to the criteria described by Stewart and Hundley. 32 patients (30.

Tendon transfers to restore elbow flexion after traumatic paralysis of the brachial plexus in adults.

Loss of elbow flexion after traumatic brachial palsy produces significant functional and cosmetic problems. Although a direct approach to the neurological lesion with an attempt to reinnervate the biceps has given some encouraging results, these can be incomplete and for this reason tendon transfers still have an important role. We report the results of our series of 60 patients (54 men and 6 women) who have undergone tendon transfer between 1984 and 1994.

[C5-C6 and C5-C6-C7 traumatic paralysis of the brachial plexus of the adult caused by supraclavicular lesions].

Purpose Of The Study: In C5-C6 and C5-C6-C7 brachial plexus palsies, prognoses was based on the recovery of a useful shoulder and elbow in order to control a normal or partially impaired hand. Treatment was an integrated procedure combining direct nerve surgery and muscle transfers.

Material: Our study was performed on 27 cases of C5-C6 plexus palsy and 43 cases of C5-C6-C7 plexus palsy operated between 1984 and 1994, with an average delay between trauma and surgery of 8 months.

Distal insertions of abductor pollicis longus muscle and arthritis of the first carpometacarpal joint in 104 dissections.

The different types of distal insertions of the tendons of the abductor pollicis longus muscle (APL) were studied in 104 cadaveric hands, and the appearance of the rhizarthrosis in the level of the basal joint of the thumb, as well, in a try to detect possible anatomical relationships. From the anatomical point of view, it was evident that the insertions of the APL muscle are usually multiple (95%), that the insertion to the base of the first metacarpal is constantly present, accompanied in 70% of the cases with an insertion to the trapezium. Finally, the accessory tendon to the thenar eminence was proved to be extremely frequent (42%).

[Bilateral SLAC (scapholunate advanced collapse) wrist: an unusual entity. Apropos of a 7000-year-old prehistoric case].

SLAC (Scapho-Lunate Advanced Collapse) wrist is the most common form of osteoarthritis of the wrist. The main aetiology is ligamentous rotary subluxation of the scaphoid. The authors report on a case of bilateral SLAC wrist, identified on a prehistoric skeleton derived from the Hassi-el-Abiod site in the malian Sahara (Dutour, 1989).

[Fractures of the wrist with cartilage rupture in young adults. Apropos of 18 cases].

Distal radius impaction fractures are not rare. They present a dual problem for the surgeon: the difficulty of establishing the exact pathological anatomy of the fracture, and of obtaining stable anatomic reduction. The authors report their experience of 18 distal radius impaction fractures in young patients after violent trauma (motor vehicle accident).

[Reconstruction of the loss of bone substance of the forearm by cubitalization of the radius (one bone forearm). Apropos of 6 cases].

Extensive forearm bone loss, whatever its etiology, presents a difficult reconstruction problem. This is mainly the case in the presence of lesions of the interosseous membrane associated with the radio-ulnar joint. When preservation of forearm rotation is not possible, cubitalization of the radius and reconstruction of the forearm by creation of a "one bone forearm" seems to be an excellent salvage technique both functionally and cosmetically.

Incidence and distribution of scaphotrapezotrapezoidal arthritis in 73 fresh cadaveric wrists.

The STT joint was examined in 73 fresh cadaveric specimens (25 male and 48 female with an average age of 84 years) with a view to study the incidence and characteristics of degenerative changes in this joint. The articular degeneration was graded from 0 to 3 according to increasing loss of cartilage and the location of the changes was noted. At the same time, the presence and extent of concomitant trapezio-metacarpal arthritis was noted.

[New metacarpal osteotomy: metacarpal cervicocapital shortening osteotomy of the rheumatoid hand].

Volar dislocation of the four long fingers is a common situation in rheumatoid hands. Surgical reduction is rather difficult because of soft tissue retraction, especially interosseous muscles, and requires large releases. The authors propose the use of Weil's osteotomy, initially described in foot surgery.

[Surgical treatment of closed articular fractures of the proximal interphalangeal joints (20 cases)].

20 cases of intra-articular fractures of proximal interphalangeal joints were reviewed with a mean follow-up of 3 years 9 months, and a minimum follow-up of 1 year, corresponding to 10 fractures of the head of P1 (7 condylar fractures, 2 supra-intercondylar fractures and 1 diaphyseal fracture with an articular crevice) and 10 fractures of the basis of P2 corresponding to distraction-impaction fractures in 8 cases. The fractures were treated by open reduction and osteosynthesis by screws, mini-screws, or pins, completed by an arthrodesis pin in 3 cases. All fractures were closed, isolated, and too unstable to be treated orthopaedically.
