[Tibialization of the fibula for a large bone loss. A case report].

A 10-centimeter tibial bone loss was treated by inter-tibiofibular bone grafting on each part of the pseudarthrosis, resulting in tibialization of the fibula. The patient was reviewed after 10 years; the clinical result was satisfactory and stable. The tibial forces were deviated on the fibula, which expressed radiologically by important thickening of its cortices. This case illustrates the interest of preserving the fibula for tibial bone loss reconstruction.

[Importance of intertibio-peroneal graft in pseudoarthrosis of the leg at risk for sepsis. Apropos of 21 cases].

PURPOSE: The purpose of our study was to analyze the use of intertibio-fibular bone grafting (I.T.F.G.) in non-union presenting a septic risk. MATERIAL AND METHODS: Twenty one non-unions of the tibial diaphysis presenting a septic risk were treated by intertibio-fibular bone grafting through a postero-lateral approach, over a seven year period (1988-1995). There were 2 septic non-unions and 19 non-unions following open fractures, all treated initially by external fixation. Seventeen patients were male, four were female. Mean age was 33 years (range 19 to 70 years). RESULTS: Healing was obtained in 20 cases, only one patient had a second bone grafting. Postoperative complications included two infections (one deep and one superficial) without consequences on bone healing. Functional results were good and excellent in 18 cases (85.7 per cent). DISCUSSION-CONCLUSION: Our study showed that among techniques for the treatment of non-union presenting a septic risk, the I.T.F.G. is one of the most reliable, with low morbidity and low cost. The authors recommend this type of surgery particularly in developing countries.

[Open fractures caused by gunshot in civilian practice. Apropos of 31 cases].

The authors report their experience of the treatment of 31 gunshot open fractures in civilian practice. The fractures, comminuted in two thirds of cases, were produced by various fire-arms. Two vascular injuries were observed. Conservative treatment was performed in 80% of cases. 13 septic complications were observed (6 superficial and 7 deep infections). The were also 7 cases of delayed union, 3 mal unions and 7 cases of joint stiffness. To improve the prognosis of these lesions, the authors emphasize that surgeons must be familiar with ballistic wounds and carry out an early initial and appropriate treatment.

[Results of an open fixation treatment of 131 fractures of the femoral diaphyses in a Congolese hospital setting].

From 1987 to 1991, 196 fractures of the femoral diaphysis were treated at the University Hospital Center of Brazzaville. A retrospective perusal of the files of these patients produced 131 analyzable cases, all treated by open osteosynthesis using either screw-attached plates (n = 84) or nails (n = 47). The overall infection rate was 5.4% (7/131). This rate was 5.9% (5/84) using screw-attached plates and 4.2% (2/47) using nails, i.e. only slightly higher than in the literature. Bone fixation was successful in 90% of cases. Mechanical complications (11.4%) were due mainly to technical errors during the initial fixation. With a follow-up of 3 years, analysis according to the criteria of GENESTE showed that open osteosynthesis of fractures of the femoral diaphysis in an African orthopedic department led to 90% of good (32%) and excellent (58%) results. In this African series, the main problem was the initial fixation.

[Acute osteomyelitis of the patella].

The authors report on an observation of acute osteomyelitis of the patella in a non-sickle-anemic 8-year-old child. The literature helps confirm the scarcity of the disease, the difficulties of diagnosis and the good prognosis of the lesion in the child.

[Recent fractures of the humeral shaft in adults. Role of surgical treatment using screwed plates. Apropos of 35 cases surgically treated].

Thirty five cases of recent fractures of the adult humeral shaft were treated by using A0 plating technics. Most of the results were satisfactory (91 per cent of good and excellent results). A few post-operative complications were observed: two deep infections, one radial nerve palsy, no pseudarthrosis. Once indicated, internal fixation using plating is the best surgical technic for the authors of the present study.

[Infected, diaphyseal pseudoarthroses of limbs. Therapeutic problems in 17 cases. (Orthopedic-traumatology service of the University Hospital Center of Brazzaville-Congo].

Seventeen cases of infected pseudarthrosis have been registered between 1987 and 1991 in the Orthopaedic Ward of the University Hospital of Brazzaville (Congo). They are distributed as follows: eleven cases located in the leg, three in the humerus, and three others in the femur. Their analysis was especially concerned with the etiological aspects of the different cases, and with their specific therapeutic strategies. The authors' conclusion points to the urge to take deterrent steps to ward off the awful complications of the disease.

[Reoperations for mechanical complications of femoral osteosynthesis. Analysis of 20 cases].

Based on a study of 220 femoral osteosynthesis, the results of 20 second surgical operations because of mechanical complications sat in 19 patients. These complications occurred on 15 screwed plates (6 breakings, 6 angulations, 3 dismounting) and 5 nailings (4 proximal migrations, 1 angulation). The critical analysis about the first osteosynthesis showed some technical error in several cases. Pseudarthrosis (9.2 p.c.) was observed in all mechanical complications at the plates A second surgical operations, thanks to a new osteosynthesis associated, in 8 cases, with a cortico-spungoïd osseous graft led to 85 p.c. of good and very good results and 15 p.c. of satisfactory results. No post surgery complication was observed.

[Galeazzi fracture. 9 cases in the orthopedic-traumatology service (Brazzaville-Congo)].

The authors give an account of nine cases of Galeazzi fractures, observed on a four-year period (1987-1991). These uncommon and unstable injuries were treated, in all cases, by rigid osteosynthesis of the radius. The treatment of the distal radio-ulnar dislocation, depending on its importance, was K-wire stabilization (4 cases), plaster-cast immobilization in supination (2 cases). There was no peculiar treatment in 3 cases. The results were influenced by operative delays. However we obtained 4 excellent results, 3 good results and 2 fair results.
