Figs. 3-A through 3-D: Case 2.
Figs. 3-A through 3-D: Case 2. Radiographs showing sequential changes that led to conversion of the lateral aspect of the proximal part of the tibia into a new femoral head over a seven-year period.Fig. 3-A: Five weeks postoperatively, there is atrophy due to inactivity of the proximal part of the tibia. The medial part of the tibia is not well centered in the acetabulum. Winfried W. Winkelmann J Bone Joint Surg Am 2000;82:814 ©2000 by The Journal of Bone and Joint Surgery, Inc.

Fig. 3-B: Three years and four months postoperatively, there are signs of remodeling, with formation of a partial femoral head and acetabulum.

Fig. 3-C: Six years and ten months postoperatively, there is increasing centering of the femoral head, which is starting to have a more normal appearance. Fig. 3-C: Six years and ten months postoperatively, there is increasing centering of the femoral head, which is starting to have a more normal appearance. The medial part of the tibial physeal plate is oriented toward the vector of force. There is appositional bone growth on the medial side of the proximal part of the tibia, and the compressive trabeculae are merging into the thickened tibial cortex. Winfried W.

Figs. 4-A and 4-B: Case 6. Figs. 4-A and 4-B: Case 6. Magnetic resonance imaging scans showing the newly formed lateral aspect of the femoral head five years and nine months after rotationplasty.Fig. 4-A: Three sections from the axial T2-weighted fast-spin-echo sequence showing good centering of the newly formed femoral head within the acetabulum. The thick cartilage covering can be seen. Winfried W. Winkelmann J Bone Joint Surg Am 2000;82:814 ©2000 by The Journal of Bone and Joint Surgery, Inc.
