Clinical effect of 20 cases of ulnar impingement syndrome treated by arthroscopic Wafer technique
Objective To investigate the early effect of arthroscopic Wafer in the treatment of wrist Ulnar Impaction Syndrome(UIS).Methods A retrospective analysis was performed on 20 UIS patients with positive ulnar variance(UV)≤4 mm admitted to Suining Central Hospital from August 2019 to September 2022.All patients were treated with arthroscopic Wafer surgery and standard rehabili-tation exercise after surgery.There were 9 males and 11 females,ranging in age from 18 to 76 years old.The course of disease ranged from 6 to 24 months.Preoperative ulnar impingement test,ulnar pressure test and Press test were positive.Preoperative carpal flexion,dorsalis extension,ulnar deviation and radial deviation were(54.2±3.8)°,(61.1±4.3)°,(15.8±4.6)°,(13.0±2.7)°,respectively.Pain vi-sual analog scale(VAS),Mayo wrist score,DASH score,grip strength,UV degree were(6.2±1.1)points,(53.5±9.1)points,(45.9±5.8)points,(60.5±9.3)N,(3.5±1.5)mm,respectively.Results All the patients' incisions healed in stage Ⅰ,and no complications such as wrist stiffness and infection occurred.All patients were followed up for 12 to 24 months.At the last follow-up,carpal flexion and dorsi-flexion were(54.7±4.1)° and(61.7±4.6)°,respectively,and there was no significant difference compared with the preoperative results(P>0.05);Ulnar deviation and radial deviation were(34.4±5.3)° and(15.6±3.5)°,respectively,and the differences were statistically significant compared with those before surgery(P<0.05);VAS,Mayo wrist score,DASH score,grip strength and UI were(1.6±0.6)points,(81.0±8.3)points,(15.7±4.2)points,(80.8±8.7)N,(0.8±0.8)mm,respectively.The above indexes were statistically significant compared with those before surgery(P<0.05).Conclusion The treatment of UIS patients with UV(≤4 mm)with Wafer surgery under arthroscopy has definite efficacy,can effectively relieve pain and improve wrist joint function,and is worthy of clinical application and promotion.
