Abstract:
Since 1856, Mayer13) coined the term “osteotomy” for a tibial resection for an angular deformity, various shapes and designs of osteotomies in long bone or pelvis have been popularized to treat the malunion, osteoarthritis of hip and knee, bow leg, L.C.P., or C.D.H. etc. The purpose of corrective osteotomy for tibia is so different from that of upper extremity because it must be restored the weight bearing alignment, and equalize or minimize the leg length discrepancy. We respectively reviewed 14 cases with various angular deformities on tibia who were treated at Dept. of Orthopaedic Surgery, Catholic Medical College from Jan. 1976 to Dec. 1984. The results obtained were as follows: 1. Causes of angular or rotational deformities of tibia were malunion in 11, bow leg in 2 and partial closure of distal tibial epiphysis in l. 2. Ten cases of tibial deformities exceeded over the 10° of medial or lateral angulation and 15° of anterior or posterior bowing were corrected for normal weight-bearing alignment in lower leg. And a rotational deformity may be so disabling to walk as to require surgery. So four cases of tibial angular deformities combined with more than 20° of external rotation and 5° of internal rotation were corrected for normal good looking walks. 3. The maximum length that can be gained by an opening wedge osteotomy was near the point of maximum angluation, but it could be changed by the cause of deformity and patient's age. We've done 4 cases of opening and 10 cases of closing wedge osteotomy. 4. Angular deformity in one plane due to fracture in children under 10 years of age may be corrected spontaneously by growth, but deformities due to bow leg or epiphyseal injury cann't be expected any spontaneous correction of deformity by growth. So three cases of tibial deformities due to bow leg or epiphyseal injury in children were corrected in earlier after recognition of that deformities because of possible damage to articular cartilage and the combined rotational deformities. 5. A slight deformity if the angulation involves near a joint, knee or ankle could be seriously disabling and so must be correctcd earlier. 6. Functional results of the corrective wedge osteotomy in angular and rotational deformities of tibia were excellent, good, fair in 4, 7 and 3, respectively.
