United Orthopedic UTF Reduced Stem 1 2 Preoperative planning is essential for determining the optimal stem size, neck resection level and the appropriate neck length. Making an accurate femoral component selection begins with thorough radiographic evaluation of the affected femur, both the A/P view and lateral view. The A/P radiographic image should include bilateral hip joints to help evaluate the affected side. These radiographs provide an estimation of leg length discrepancy, femoral offset and center of rotation needed to reconstruct hip biomechanics. The UTF Reduced stem is designed to provide immediate geometrical stability through contact with the medial and lateral cortex. Standard and high offset options are available. It is recommended to pre-operatively template the prosthesis size that best fits the metaphysis canal area. Templates show the neck length and offset for each of the head/ neck combinations (-3 to +10 mm, depending on head material and diameter). The final determination of implant choice should take into account the acetabular cup position, cup size, and hip center. Preoperative Planning andTemplating During preoperative templating, determine the neck resection level by referencing the distance above the lesser trochanter (about 10-15 mm) Intra-operatively, align the Neck Resection Guide with the anatomical axis of the femoral canal. Mark the cut line using electrocautery, then complete the femoral neck resection with a power saw. Remove the femoral head with the Femoral Head Extractor . Femoral Osteotomy Instruments A.
