Long-term outcome lengthening and axis correction with the Ilizarov method in post-inflammatory shortening and deformity of the humerus.

Background. Post-inflammatory shortening and deformation of the humerus results from damage to the epiphyseal cartilage of this bone, and in particular to the proximal growth plate, most commonly caused by neonatal staphylococcemia. This is frequently accompanied by shortening of the femur, deformation of the hip and knee joints, the temporo-mandibular joint, and occasionally other joints as well. In the present article the authors present their own experiences with the application of osteogenesis in the post-inflammatory shortening and axis deformation of the humerus.
Material and methods. The clinical material consisted of 23 patients treated during the period 1995-2000 at the institutions represented by the authors in Wroclaw and Lodz. The average shortening was 8,5 cm (31,3%), and the average follow-up period was 2 years.
Results. The average lengthening achieved was 7,5 cm (40,5%), and the average lengthening index was 22,7 days/cm. complete axis correction was achieved in all patients with deformities of the humerus. More exact monitoring of the distraction process is necessary in the arm than in the lower limbs. Only 2 problems and 2 obstacles (according to Paley's classification of complications) were encountered in the course of treatment.
Conclusions. The results obtained indicate that the Ilizarov method is a safe and effective technique for the treatment of shortening and axis deformity of the humerus.
