Intraoperative method of femoral head central measurement to prevent leg length discrepancy following hemiarthroplasty.

As shown in Table 3 , the median number of VD-CFH-TGTAAF, leg length, and FO on the nonoperative side were 6.35 mm (IQR, 4.33–9.75 mm), 15.10 mm (IQR, 12.30–20.11 mm), and 49.20 mm (IQR, 46.50–52.70 mm), respectively, and the operative side was 5.50 mm (IQR, 4.22–6.82 mm), 13.10 mm (IQR, 9.30–18.07 mm), and 51.60 mm (IQR, 47.50–54.85 mm), and the differences between the operative and nonoperative sides did not reach statistical significance ( P = 0.182; P = 0.079; P = 0.278).
