Alt ekstremite uzun kemik deformalitelerinin Ilızarov yöntemi ile düzeltilmesi

Abstract

ABSTRACT Correction of the Deformities in Long Bones of the Lower Extremity by Bizarov Technique From November 1993 to December 1997, Dizarov method was performed on 18 limbs of 16 patients in order to correct lower-extremity deformities of varying causes, in the Çukurova University Medical Faculty, department of Orthopaedics and Traumatology. There were 7 males and 9 females with a mean age was 1 8 years (range,5 to 51). 7 femorae, 16 tibiae of the patients were corrected for a mean deformity of 26° in frontal, 24° in oblique, 70° rotational axis. The mean duration of treatment from application to removal was 25 weeks (range, 15 to 48). The mean duration of follow-up was 13 months (range,4 to 37). Preoperative long-standing anteroposterior and lateral radiograms of the entire lower extremity were compared with those obtained at the most recent follow-up visit after the correction. Lower extremity alignment and joint orientation were the two parameters, used to check the correction of deformities. Alignment was determined by mechanical axis deviation (MAD). Hip,knee and ankle orientation angles were also used to determine the magnitude of deformity of each bone. The preoperative and postoperative MAD averaged 29mm and 7mm, respectively. All deformities were corrected successfully and the magnitude of residual deformities were neglectable. During the treatment 48 complications were occurred. Of these, 40 (%83)wçre problems, 5 (1 1%) obstacles, 3 (%6) true complications. As anticipated, the prevelance of true complications was highest in patients who had had- complex deformities and prolonged treatment time but the rate of problems and obstacles were relatively constant as in the other cases in which Ilizarov techniques were used. IXAt the end of the treatment, 96 % good or excellent bone results, 88 % good or excellent functional results were obtained. Also 96 % of patients improved their activity level, as compared with preoperative activity. Success of accurate correction of complex deformities of long bone and lower complication rates in these patients, make the Ilizarov technique an attractive method for correction of deformities, until the better procedures are discovered. Key words: Long bone deformities, Ilizarov technique, correction of lower extremity deformites
