Evaluation Of Patients With Carpal Tunnel Syndrome Treated By Endoscopic Technique

Objective: Carpal tunnel syndr ome( CTS) is a c ommon c ompression syndrome in peripheral nerve, it is caused by the compression of the media nerve within the carpal tunnel in the wrist. In milder cases, conservative treatment can be chose, if the conservative treat ment fails and patients are in a bad state of illness, surgery should be performed.With the devel opment of medical science, minimally invasive surgery bec ome a trend. With the research of the patients who underwent endoscopic carpal tunnel release(ECTR),this article try to explore the therapeutic effect and safety of the endoscopic carpal tunnel release.Methods: By collectingthe clinical data of 106 cases 112 sides of idiopathic carpal tunnel syndr ome that were treated in the depart ment of hand surgery of the first affiliated hospital of Dalian medical university fr om Jan 2010 to Jan 2014 retrospectively, with 10 males 11 sides,96 females 101 sides, their average age was54.5(30-86) years, their average course of disease was 10.2( 6-21) months.All the patient were treated by the sa me person,full of experience,with the Chow’s ECTR.The evaluation includes DML and t wo-point discri mination of the pre-operation and 6month after the operation, The self-a dministered Boston Questionnaire was used to assess the severity of patients’ sympt oms and their functional status,each patient’s symptom, amelioration, complication, operation time, hospitalization time, RSD, and the OPD). Analyzed by analysis of variance T test, Ridit test P value was set on 0.05.Results: operation time 13±1.3 min, hospitalization time 2.3±1.1d, little of the hemorrhage during operation,time of return to work18.6±2.1d, wound length1.0±0.3cm, Over 6 months of continuous visit after surgery, All cases were followed up there is no complications of incision infection,ulceration and tendon injury, but nerve injury(2 cases) and Postoperative Hematoma(1 cases), RSD(7 cases),the incidence rate of the complication is 8.9%.The symptom of subjective numbness remission was satisfying,96 cases significant relief(85.7%), 14 cases relief(12.5%),2cases invalid(1.8%) 6 month after the operation. There was a significant decrease in the BCTQ compared with pre-operation and post-operation(P<0.01), the BCTQ50% inclined compared with pre-operation and 6 month after operation. DML and two-point discrimination also improved significantly.Conclusions:ECTR can obviously improve the symptoms of subjective numbness.The function of hand can improve enormous, but with certain complications,especially the coincidence of reflex sympathetic dystrophy(RSD).
