The effects of an early intrahospital rehabilitation on weight bearing during lower extremity lengthening with Ilizarov method.

PURPOSE Exerting axial pressure on the affected lower limb remains one of the most crucial elements of Ilizarov method. The objective was to determine the effects of an early intrahospital rehabilitation on weight bearing during lower extremity lengthening with Ilizarov method. METHODS The study included 15 patients who underwent lower limb lengthening. The patients were tested on the third day after surgery using the pedobarographic platform. The tests were performed four times in the standing position: twice with the support of forearm crutches and twice without crutches. Patients were asked to either remain in the relaxed standing position (two tests) or use the lower limb equipped with Ilizarov apparatus to support the body weight (two tests). RESULTS In relaxed stance average pressure with forearm crutches was 24.1% for affected limb, as compared to 75.9% for the healthy limb. In test without forearm crutches average pressure for affected limb was 26.1%, as compared to 73.9% for the healthy limb. Patients shifted body weight to the affected limb with forearm crutches on average, at the rate of 53.6%. In test without forearm crutches the affected limb was supporting the body weight at the rate of 48.26%. None of the patients was able to fully support the body weight on the affected leg. CONCLUSIONS In spite of strict physiotherapy regimen, patients are neither able to equally distribute their body weight between the two lower limbs nor to shift their body weight to the limb equipped with Ilizarov apparatus.
