Effect of hip replacement surgery on clinical efficacy, VAS score and Harris hip score in patients with femoral head necrosis.

Aim: To study the effect of hip replacement surgery on the clinical treatment efficacy, VAS score and Harris hip score of patients with necrosis of the femoral head (NFH). A total of 86 patients with NFH who were treated in our hospital from January 2016 to January 2019 were selected as the research subjects, and were divided into the control group (n = 43, conventional artificial hip replacement) and the observation group (n = 43, modified version of artificial hip replacement) according to a random number table method. The treatment efficacy, pain, hip function, motor function and adverse reactions of the two groups were compared.

Results: The effective rate of the observation group was 93.02%, which was higher than 79.07% of the control group (P<0.05). There was no difference in VAS scores of the two groups before treatment (P>0.05); after treatment, VAS scores were reduced, and the observation group was lower than the control group (P<0.05). There was no difference in Harris hip scores between the two groups before treatment; after treatment, the Harris hip joint scores were elevated, and the observation group was higher than the control group (P<0.05). There was no difference in Fugl-Meyer motor function scores between the two groups before treatment (P>0.05); after treatment, Fugl-Meyer motor function scores increased, and the observation group was higher than the control group (P<0.05). The incidence of adverse reactions in the observation group was 6.98%, which was lower than 16.28% in the control group, and the difference was not statistically significant (P>0.05).

Conclusion: Modified artificial hip replacement is effective in treating NFH. It can relieve pain, improve hip joint function and motor function, and has high safety and is therefore worthy of promotion.
