ABSTRACT: Introduction: The progressive osseous lengthening on a single site corticotomy such as described by Ilizarov is a reliable but difficult method in the treatment of limb length discrepancies. The objective of this study was to appreciate the results of the recent application of this method in a low-income country such as Senegal. Material and Method: It was a retrospective study on 32 patients among whom 19 were men (people) and 13 were women over one continuous period of 7 years. The mean age was of 19 years with extremes of 10 and 36 years. Etiologies were dominated by osteoarthritis of the hip in 77.8%, traumatic sequela in 16.7% and the aseptic osteonecrosis of femoral head in 5.6%. The average duration of treatment was of 232 days with extremes of 110 and 363 days. Results: On the anatomical plan, the average lengthening was 55.89 mm that is 12.03% of the initial length with extremes of 35 and 110 mm. The equalization, in terms of length of the members, was obtained in 33.3% of the cases. The average index of cure was of 56.29 days, six patients, which are 18.75% of the cases, complained about pain at the end of treatment and walking without crutches was possible in 83.33%. The complications, in the phase of lengthening, were either mechanics, with 5 subluxations (3 at the level of the hip and 2 at the level of the knee), or biological with 7 infections (superficial 5 and 2 deep), 2 premature consolidations and 1 bleeding. The complications in the consolidation phase were also mechanical with 32 articular stiffness, 8 plastic deformations, 7 subluxations, a fracture and a collapse of the regenerate, or biological with 8 infections among which an osteitis and bleeding. Conclusion: Despite a strong rate of complications and sometimes not reached objectives, the results of this first series of lengthening are encouraging and rich in education and do not seem to be a limiting factor for the implementation of the method in developing countries.
