بررسی نتایج عمل جراحی طویل کردن اندام تحتانی در 21 بیمار مبتلا به نابرابری طول اندام تحتانی بستری در بیمارستانهای همدان در طی سالهای 78-1366

Discrepancy in limb lengths (anisomelia) is a common orthopedic     problem, arising from either shortening or overgrowth of one or more bones    in the limbs. The object of this study was determination of lower limb    lengthening operation results in 21 patient with lower limbs - length    discrepancy that were admitted in Hamadan Hospitals in 1987- 1999.           In this Cross - Sectional Descriptive Study , all lower limb lengthening    operated in Hamadan Hospitals in 1987 - 1999 were studied. Primary data    were recorded on the basis of patients files in hospital, then the necessary data    were completed using the patients files in the private centers and later    examination. Finally collected data were analyzed by EPI Info 6 software.           The mean of age in the studied patients was 16.6± 4.9years. The most    frequency of patients age (38%), was in age group of 13-15 years. 90.5% of    patients were operated by leg lengthening and 9.5% of them by  thigh    lengthening. 71.5% of patients were obtained increasing of length amounting    to 30-55 mm in involved limb after operation. “ Wagner” external fixator was    used in treatment of 14.3% of patients. 14.3% of patients needed corrected    surgery before main surgery. 85.7% of patients needed complementary surgery    after main surgery. The most common minor complication after lower limb    lengthening operation created in 90% of patients was pain. The most common    major complication after lower limb langthening operation was severe    equanus deformity of foot that was created in 57.1% of patients.           Evaluation of 21 lower limb lengthening operation showed that more    attention should be paid to lower limb lengthenig operation because of    poliomyelitis handicaps and war handicaps and accessibility of instruments    for operation which not only can solve cosmetic problems but also    functioning of handicaps
