  • Title: Comparison of preoperative templating with postoperative assessment in cementless total hip arthroplasty.
    Author: Suh KT, Cheon SJ, Kim DW.
    Journal: Acta Orthop Scand; 2004 Feb; 75(1):40-4. PubMed ID: 15022804.
    Abstract:
    We studied how preoperative templating corresponded to the postoperative leg length in total hip arthroplasty. On average, the preoperative predictive value of the desired corrective change in leg length was +4.9 (+4.0-+6.7) mm, while the true postoperative assessed value of the corrective change in leg length was +4.7 (+4.0-+6.3) mm. On preoperative radiographs, the ratio of the horizontal offset of a pathological side to a normal side was 95%, on average, and it increased to 96%, on average, after an operation. Preoperatively planned sizes of the acetabular cup and the femoral stem by templating showed a high rate of coincidence with the sizes used intraoperatively. In conclusion, an accurate and careful preoperative templating can result in a balanced hip reconstruction by correcting the leg length differences and restoring the offsets.
