graphic file with name IORT_A_1941628_F0004a_B.jpg — a. Preoperative radiographs of a 6-year-old female with OI type III with bilateral antero-lateral deformity of the femur and tibia and tibial pseudoarthrosis. Repeated fractures, inability to weight bear or ambulate with unaffected upper extremities indicated candidacy for IM rodding.

b. Postoperative radiographs. Femur: correction of malalignment with telescoping rods. Proximal female threads are inserted in greater trochanter not crossing the trochanter apophysis.

Tibia: female threads are positioned into the proximal tibial epiphysis, not crossing the physis. Threads of the male rod are inserted in the distal tibia epiphysis not protruding into the ankle.
