[Traumatic posterior dislocation of the shoulder in adults. Apropos of 25 cases].

In a series of 25 traumatic posterior dislocations of the shoulder treated from 1960 to 1985, 16 were overlooked and the time from injury to treatment ranged from 3 weeks to 14 months. 11 cases were secondary to motor vehicle accident and 14 occurred after a convulsive fit. Early closed reduction was effective in only 4 cases; in 2 cases, reduction was unstable and further screwing of an associated fracture of the tuberculum majus was performed to prevent redislocation; 3 locked dislocations necessitated open reduction and stabilization by subscapularis transposition into the defect of the humeral head. Most of the 16 chronic unreduced dislocations were treated by the same procedure. Overall, 21 cases were reviewed with a mean follow-up of 14 years. Functional outcome was more often satisfactory in acute (5/7) than in old unreduced dislocations (6/14). Mc Laughlin or Neer's procedures yielded good results in 9 out of 14 cases; they are indicated irrespective of the patient's age whenever Mc Laughlin's notch does not involve more than one third of the articular surface of the humeral head.

Patellar metastasis from a large bowel adenocarcinoma.

Although bone tumors are often located in the knee area, primary tumors of the patella are rare (6, 8), and patellar metastases even rarer. A few cases were reported in the literature, originating from the breast, lung, kidney, uterine cervix and oesophagus. We report a case, for the first time to our knowledge, of a patellar metastasis from a large bowel carcinoma.

[Scaphoid-trapezium-trapezoid dislocation. 5 cases].

The authors report 5 cases of scaphoid-trapezium-trapezoid dislocation (STT) which occurred in crush injuries of the hand. A good functional result was achieved by closed reduction and pinning whenever there was no associated soft tissue damage. However, lateral mid carpal osteoarthritis may develop and produce reduction of the abduction of the thumb as well as slight stiffness of the wrist.

[A comparative study of the treatment of fractures of the radial head by resection or by Swanson silastic implant].

The authors report 62 fractures of the head of the radius treated either by excision or silastic implant arthroplasty. Fifty-two patients were reviewed with a mean follow-up period of 5 years (range 1 to 13). Of 22 prosthetic replacements, 12 were satisfactory while of 30 excisions only 10 were rated good or excellent. Excision usually yielded valgus deformity of the elbow (range 9 to 35 degrees) and with a risk of shortening of the radius. Range of flexion-extension was identical after both procedures but pronation supination was better after prosthesis replacement (78/70) than after radial head excision (65/60) 3 fractures of the implant were found at 6, 9 and 10 years postoperatively; only one of them was associated with pain and required removal of the loose fragments.

[Correlation and validation of different methods of evaluation of results after surgery of the rotator cuff. Plea for a standardized method].

Several charts elaborated for the assessment of the results of surgical treatment of cuff rotators tears were critically analysed. Twenty-one patients were reviewed and results assessed with three different charts, the Patte, Kenesi and Constant ones. The correlation of the parameters was studied and was found to be satisfactory.

[Original treatment of a supramalleolar pseudarthrosis in an impaired position].

The authors report the case of a nonunited supra-malleolar fracture with severe angulation in an elderly patient. Poor vascular condition and severe osteoporosis prevented the use of either a surgical approach or internal fixation. Gradual realignment and union were nevertheless achieved within 6 months post operatively using the "Sequoïa" external fixation system, while weight-bearing was continued throughout the course of treatment.

[Injuries to the upper tibial epiphysis. Apropos of 20 cases].

The authors report 20 cases of injuries involving the proximal tibial epiphysis (16 avulsion fractures of the tibial tubercle, 4 epiphyseal fractures), occurring in adolescents engaged in athletics, in 3/4 of the cases. Sixteen displaced fractures needed open reduction and internal fixation with screw(s). Leg shortening (12 mm) occurred in a 14 year-old male with a displaced fracture of both the tibial tubercle and proximal epiphysis, in which premature ossification had taken place; fixation with Kirschner wires would have been the treatment of choice before closure of the tibial epiphysis. At follow-up, function was acceptable in all cases; all the patients had returned to full daily activity and no further surgical procedures were needed. Long-term knee laxity became obvious in one patient, however, with repeated fracture of the tibial tubercle. Associated ligamentous and meniscal tears should therefore be sought on early clinical examination and confirmed by arthroscopy or arthrotomy after surgical fixation.

[Anterior peri-lunar dislocation of the carpus in children. Apropos of 2 cases].

Volar perilunar dislocation of the carpus in children, in view of their rarity, represent a pitfall in traumatology which can be avoided by means of careful x-ray examination. The rarity of the lesion can be explained by the fact that cartilagenous structures of short bones and epiphyses are more resistant than ossified structures. The study of the 2 cases of volar perilunar dislocation of the carpus in an 11 1/2 years old and a 12 years old child respectively as well as a review of the literature confirms that its mechanism is due to extreme palmar flexion, and explains associated bony lesions. It permits an adapted treatment according the nature and age of the lesion. Despite insufficient follow up time, the functional outcome seems satisfactory.
