ABSTRACT
Objective To observe the relationship between the skin incision of anterior cruciate ligament(ACL) reconstruction and the sensory disturbance around the surgical incision of the leg.Methods From Oct 2007 to Jun 2008,223 patients underwent arthroscopy ACL reconstruction,among them 50 patients were followed-up and defined as four groups according to different types of skin incision.The area of skin sensory disturbance around the incision were measured and compared.Results Compared with transversal incision group(transversal incision for double bundle ACL reconstruction),vertical incision group(using hamstring or Bone-Patella-Bone autografl for ACL reconstruction) and posteromedial incision group(medial meniscus repair group),the length of incision in small incision group(using allograft for ACL reconstruction)was significant shorter(P<0.001).For the area of sensory disturbance,there were no statistics differences between small incision group and transversal incision group(P=0.800),and no statistics differences between vertical incision group and posteromedial incision group(P=0.316).But both small incision group and transversal incision group showed significantly smaller(P<0.05)area of sensory disturbance than vertical incision group and posteromedial incision group.Conclusion For ACL reconstruction,using small incision(allograft)and transversal incision could decrease the area of sensory disturbance of anterior tibial skin.
ABSTRACT
OBJECTIVE To apply a low temperature hydrogen peroxide gas plasma sterilization for the heat intolerant orthopedic instruments.METHODS A comparison of the sterilizing effects of the orthopedic(instruments) was made among the low temperature hydrogen peroxide gas plasma sterilization,the ethylene oxide sterilization and the 2% glutaraldehyte(GTA).RESULTS Twelve hours were spent in the sterilization to the undurable(orthopedic) instruments when the ethylene oxide was used,and 10h were needed using the 2%GTA.but,55 min were enough using the low temperature hydrogen peroxide gas plasma.CONCLUSIONS The low temperature(hydrogen) peroxide gas plasma sterilization is applicable to rapidly sterilizing the heat undurable orthopedic(instruments) characteristically with the high effects,quick speed and convenient.
