Abstract:
Objective To investigate the feasibility and results of unilateral Crowel Ⅳdevelopmental dyspepsia of the hip(DDH)length of bone shortened in operation by using adjustable orthopedics and measuring the double leg length X-ray PA at erect position before operation. Methods Totally 18 unilateral Crowel Ⅳ DDH patients underwent total hip replacement(THR)between January 2013 and June 2014, there were 6 male and 12 female patients with a mean age of (47.5 ± 3.1) years old. Before operation, the double leg length X-ray PA was measured, lumbosacral portion pain by Numeric Rating Scale(NRS)and activities of daily living(ADL) were assessed. The responsible nurses provide comprehensive health education and instruction on functional exercises, instruct patients to wear adjustable orthopedics to walk until they felt two legs were equilong and a balanced walking for one month. With the orthopedics'adjustable height and the double leg length X-ray PA at erect position, calculating the length of bone shortened in operation. Postoperative follow-up was carried out for (2.7±0.2) years, the lumbosacral portion pain was assessed by NRS and ADL at last follow-up. Results On the last follow-up, there was a normal gait, the lumbosacral portion pain assessed by NRS, ADL score, score of physical self-maintenance dimension, score of instrumental activities of daily living dimension were 3.1±0.6, 76.2± 4.7, 18.2 ± 8.2, 44.8 ± 6.1, and were 8.7 ± 0.3, 43.3 ± 9.5, 31.4 ± 3.6, 25.1 ± 9.8 before operation, there were statistic differences between them (t=6.25-35.41, P<0.01). Conclusions Using adjustable orthopedics before operation can calculate exactly the length of bone shortened in operation, simplify the operation process. After operation, there is obvious gait improvement and satisfying clinical effect.
