掌侧开窗撬拨技术在老年桡骨远端骨折手术中的应用OA

Objective To explore clinical efficacy of palmar incision and levering technique in the surgical treatment of distal radius fractures in the elderly.Methods From October 2022 to December 2023,28 patients with distal radius fractures who underwent surgical treatment were admitted.Among them,including 10 male and 18 female;the age was 68(64,72)years old;the disease duration was 3(2,7)days;bone density was-3.1(-2.7,-3.3);11 patients on the left side and 17 patients on the right side;19 patients caused by injuries,and 9 patients caused by traffic accidents;according to AO classification,20 pa-tients with type A3 and 8 patients with type C2.Palmar inclination angle,ulnar deviation angle and radial height before treat-ment and the latest follow-up were observed and compared.The modified Mayo wrist score(MMWS)was used to evaluate the recovery of wrist joint function.The fracture healing and the occurrence of complications were also observed.Results All pa-tients were followed up for 11(9,13)months.None of patients experienced complications such as incision infection,re-loss of fracture reduction,or non-union of fractures.The palmar inclination angle,ulnar deviation angle,and radial height improved from(-2.7±1.5)°,(16.2±2.7)°,and(2.1±1.3)mm before treatment to(12.1±2.6)°,(20.6±2.1)°,and(10.5±1.2)mm at the latest follow-up,and the differences were statistically significant(P＜0.05);at the latest follow-up,MMWS score was(94.3±3.7)points,with 23 patients got excellent result and 5 good.Conclusion Palmar window dislocation technique for treating patients with osteoporotic distal radius fractures could effectively restore palmar inclination angle of radius.Combined with the implan-tation of artificial bone,it could effectively maintain the fracture reduction and reduce risk of re-displacement.
