Clinical application of arthroscopic arthrolysis for the treatment of elbow stiffness / 局解手术学杂志

ABSTRACT

Objective To evaluate the clinical results of arthroscopic arthrolysis for the treatment of elbow stiffness.Methods Totally 34 cases with elbow stiffness caused by trauma who needed to undergo arthroscopic arthrolysis were selected from General Hospital of Shenyang Military Area Command from October 2014 to February 2016.Among them,3 cases were lost to follow-up,and the other 31 cases were included in the study.All the patients were performed arthroscopic arthrolysis.Removed the hyperplasia of osteophyte and girdle,cleaned the articular cavity,restored the smooth of articular surface,and released the joint capsular and ligament around the elbow joint during the operation.Manipulation release was used coordinate with analgesia and rehabilitation therapy after operation.Mayo scores of elbow were used for function evaluation and range of motion(ROM) was collected.Results Patients were followed-up from 9 months to 12 months,(10.4±1.5) months on average.Before the operation,the mean maximal flexion angle of the elbow was (87.6±5.9)°,the extension angle was (35.5±6.4)°,the pronation angle was (75.9±9.6)°,the rotational angle was (67.2±7.4)°,and it was (125.9±6.5)°,(5.0±1.9)°,(82.0±9.1)°,(81.0±7.0)°respectively after operation,and the differences before and after opreation were statistically significant (P<0.05).The Mayo scores was (61.9±7.6) preoperatively and (88.8±4.7) postoperatively,and the difference was statistically significant(P<0.05).Conclusion Arthroscopic arthrolysis has the advantages of clear operative field,minimal invasion and rapid recovery.It can effectively improve the elbow joint activity and arthroscopic arthrolysis is an effective surgical treatment for elbow stiffness.
