[The Roseland prosthesis].

Total joint replacement of the trapezio-metacarpal (TMC) joint is one of the procedures available for the surgical treatment of degenerative osteoarthritis or rheumatoid arthritis of the first carpometacarpal joint. A four French Alpine surgeon group, (C. Lebrun, P. Massart, F. Moutet and C. Sartorius) have developed a new cementless total TMC joint prosthesis: the Roseland prosthesis. Such a device tries to improve the biomechanical conditions of the La Caffinière's implant, which was introduced in 1973. Clinical data of a 24 patients with a 38 month mean follow-up series are reported.

[The value of combining multiple screwed plates in humeral shaft fractures].

The authors have reviewed 246 fresh fractures of the shaft of the humerus treated by primary plating over a period of 22 years. It has been customary to treat the majority of fractures of the shaft of the humerus by conservative means, with use of open reduction and fixation by a plate for complicated fractures with associated injuries, or in cases of nonunion. Over the period of review the authors have gradually increasing their use of primary plating as opposed to the traditional methods. They fell that the reliability of union, together with the early mobilisation and return of the arm to normal function, favours the use of this method. Their opinion is based on a careful analysis of their results.

The operative treatment of intraarticular calcaneal fractures. Indications, technique, and results in 257 cases.

Since 1972, 257 intraarticular fractures of the calcaneus have been treated with operative intervention. A lateral incision and a third tubular plate were used in all cases. The functional results were considered excellent or good in 85%, and there was an infection rate of 2.7%. Although 50% of patients showed a reduced mobility of the subtalar joint, pain and limited ambulation were rare. Only six patients required a late subtalar arthrodesis.

[The Herbert screw in pseudoarthrosis of the carpal scaphoid].

For nearly three years, the authors have ensured scaphoid union by fixation with a double thread T.J. Herbert's screw. In these 25 cases a cancellous bone graft was used to fill the defect which would have left shortening of the scaphoid Twenty-two of the 25 cases, obtained rapid union, and 20 had a good or very good clinical result. One doubtful union and two cases of non-union occurred. One of these non-unions required revision. The main advantage of this procedure is to allow early mobilization of the wrist. This early is very appreciated by the patients who were immobilized several months by conservative treatment for their initial fracture.

Metacarpo-phalangeal thumb sprains based on experience with more than 1,000 cases.

The metacarpo-phalangeal thumb sprains are very frequent. They mostly occur during sports (50%), and the ulnar collateral ligament is the structure most frequently ruptured (86%). Surgical repair of all severe lesions and/or bony fragment avulsions has led to 90% of good, and excellent results, when the operation is followed by a proper physical therapy. Criteria for evaluation are considered and so is the management of the old or neglected sprains.

[Joint lesions of the first column of thumb].

Lesions involving the thumb from the interphalangeal joint to the trapezo-metacarpal (TM) joint are very frequently the result of sports injuries. The authors discuss the most frequent lesions: 1) Dislocations of the metacarpo-phalangeal (MP) joint of the thumb which can be reduced in almost every case by means of well conducted orthopaedic manoeuvres. 2) Sprains of the MP joint of the thumb, very common lesions the severity of which must not be underestimated and which always require surgical treatment in the serious lesions, regardless of the compartment involved (radial or ulnar). 3) Bennett's fractures or fracture-dislocations of the TM joint; when neglected inadequately treated, these lesions lead to disabling post-traumatic arthritis of the TM joint. A poor result of treatment for any one of these three lesions always compromises opposition of the thumb and/or the strength of pollico-digital grip.

Reanimation of thumb opposition by the extensor pollicis longus. Report of sixteen cases.

Among some 65 techniques for restoring thumb opposition found in literature, the authors chose the extensor pollicis longus transfer (EPL) onto the abductor pollicis brevis (APB) through the interosseous membrane. This technique described by Duparc et al. in 1971 was codified by Bureau et al. in 1980 using a series of 9 cases. The sufficient force and length of this transfer, associated with its direct course by redirection through the interosseous membrane make it a docile, reliable motor unit as shown by the 16 cases studied. Performed on 11 median-ulnar palsies, 6 isolated median palsies and on one complete avulsion of lateral thenar muscles, only 16 of these 18 transfers could be satisfactorily followed and reviewed from 7 to 35 months later. In our series, 14 of the 16 cases have recovered functional opposition and are using it. After a review of the surgical technique the authors emphasize some practical aspects: dissection of the EPL which may be delicate, resection of the IM which should be adequate, and choice of the reflexion pulley and how to construct it. Results as well as sequelae linked to the choice of the EPL are then analysed.

Comparison of the efficacy and tolerance of isoxicam and piroxicam following surgery for skiing accidents.

1 A 10 day double-blind study was carried out comparing isoxicam (300 mg day-1) and piroxicam (40 mg day-1 for the first two days and 20 mg day-1 for the remaining days) following surgery in patients who had sustained skiing accidents. There were 20 patients in each group. The isoxicam-treated group had a slightly greater mean pain score prior to treatment. 2 Both isoxicam and piroxicam reduced pain and nocturnal awakening at days 5 and 10, but isoxicam was significantly superior to piroxicam in producing improvement in pain (at day 5, P less than 0.05) and in nocturnal awakenings (at day 10, P less than 0.05). 3 Both agents facilitated rehabilitation and there was no significant difference between them in this regard. 4 All patients in both groups considered themselves 'better' or 'much better' on day 5 of treatment. 5 Both agents were well tolerated by most patients but one patient in each group left the trial because of abdominal pain. One patient stopped isoxicam when she was found to be pregnant.

Restoration of the pulp with a homodigital neurovascular flap.

A homodigital neurovascular island flap was used to cover extensive loss of finger tip tissue exposing the distal phalanx in twenty cases (16 adults and 3 children). The anatomic and technical aspects of this flap are detailed. In all cases, the reconstructions were considered to be of excellent quality. The study of functional results substantiates the reliability of this island flap, for which sensibility remained good throughout the follow-up period.

Severe metacarpophalangeal sprain of the thumb in ski accidents. 125 surgical repairs in group of 340 cases of metacarpophalangeal sprains from ski accidents.

In more than 12,000 ski accidents seen during 15 winter seasons (1968-1983), 340 cases of metacarpophalangeal sprains of the thumb were encountered. One hundred fifty-nine were labeled as severe, and 125 of these involving the ulnar slope of the articulation were operated as very urgent or urgent. Three types of anatomic lesions were seen at operation. Capsulo-ligamentous lesions are the most frequent (70%), followed by avulsions of large fragments from the base of teh first phalanx attached to the ulnar ligament as well as to the palmar structures (30%). Finally the true fracture of B. Stener is altogether exceptional (1 in 125). Then follows in detail the operative procedures and long term results, which confirm the excellent prognosis of this group of lesions operated early.

Value of immediate mobilization in proximal interphalangeal volar plate avulsions.

Volar plate avulsion at the proximal interphalangeal (PIP) joint, either poorly managed or left without treatment, may expose to severe PIP stiffness. The authors systematically employ early mobilization to treat this type of lesion. Rehabilitation is confided to a physical therapist trained in hand rehabilitation and seen weekly or twice a month by the supervising surgeon. In a series of 100 volar plate avulsions demonstrated by X-rays, this kind of easy and adaptable treatment can provide up to 98% of good to very good results. This completely justifies the authors' choice.

[Supracondylar fractures of the elbow in children and osteosynthesis by "open sky" double wiring using J. Séror's method. Apropos of 100 cases].

Emphasis is placed on the value of treating supracondylar fractures of the elbow with displacement (stages III and IV) in children by means of the technique described, in 1959, by J. Séror, J. Rives, J. Frailong, and Cl. Azoulay: "open sky" reduction through a twofold internal and external paratricipital posterior approach; maintenance of reduction by two Kirschner wires entering by the epicondyle and epitrochlear, with fixation into the opposite diaphysial cortex, and sectioned and curved inwards in order to remain subcutaneous. Analysis of the results of 100 cases treated in this manner between 1970 and 1980 (Thesis of Cl. Darmon, Grenoble) demonstrated the value of this technique: long-term follow up in 58 cases showed no poor results and 53 (91.5 p. cent) perfectly normal elbows totally identical to those of the opposite side. More extensive use of this technique, as practised in countries other than France and particularly in German speaking countries, is advocated.

Segmental shortening of the ulna in some malunions of the distal radius.

In patients who have a malunion of the distal part of the radius with a shortened radius, the ulna is too long. A discrepancy between the ulna and the lower radius, and between the ulna and the carpal bones occurs, compromising the mobility and appearance of the wrist. We reviewed ten such patients in whom the ulna was shortened by performing a resection of a diaphysar cylinder followed by a plate osteosynthesis. This method restored the normal anatomy of the distal radio-ulnar joint, markedly reduced the patient's pain and improved pronation and supination. When performed in young patients, when the radial deformity is not very important, this procedure has most satisfying functional results.

Screw or mini-plate fixation in fractures of the first metacarpal. Experience with thirty-nine cases.

Re-establishing normal osteoarticular anatomy, and early mobilization are the principal elements in the successful treatment of fractures of the base of the first metacarpal. To achieve these goals in thirty-nine fractures rigid fixation was obtained by screw alone, or by a mini-plate. Seven Bennett's fractures have been treated by screw fixation when the size of the fragment has made it possible. Extra-articular fractures have been treated, either by screw alone, in oblique fractures (7 cases). Or by mini-plate, T or L shaped, in transverse fractures (23 cases). The use of these techniques have been extended, to comminuted fractures but is not used in Bennett's fractures when the fragment is too small to allow the screw to be anchored in it without its being shattered.
