Ultrasound Of Cubital Tunnel Syndrome After Preoperative Clinical Application Value

Objective:Understanding of cubital tunnel syndrome(CTS)patients with nerve ultrasonic change, measuring the tickest cross-sectional area,the use of the results to determine the severity of patients preliminary discussion on ultrasound as CTS patients clinical classification the feasibility of auxiliary examination.And using ultrasound to observe the morphology of ulnar nerve surgery,a preliminary discussion on ultrasound is used to evaluate the feasibility of postoperative neurological recovery.Materials and Methods:This research starts from May 2013 to the end of December 2014,collected from our hospital orthopedic total 65 cases of patients, among them,the bilateral 19 cases,unilateral 46 cases,a total of 84 elbow. According to the results of clinical, ill elbow can be divided into light, medium, heavy three groups,including light 24 cases,25 cases of medium and heavy 35 cases.Line of ultrasound in patients with CTS,longitudinal section and cross section,the combination of observing the morphology of ulnar nerve,confirm the conformity of parts and the cause of the entrapment,measuring the thickest cross-sectional area.And according to the ultrasound group of electromyography results, and according to the ROC curve to determine the diagnosis index.For postoperative patients with ulnar nerve ultrasonic review,observing the morphology of ulnar nerve.Results:1.Patients with CTS ultrasonographic performance:55 CTS patients with ulnar nerve visible press-fitting, conformity of local nerve change thin,flat,conformity of the proximal and distal nerve enlargement,internal echo;17 CTS patients with nerve not seen conformity of points,only nerve in the elbow swelling,enlargement;12 the mild CTS patients did not see the ultrasound nerve press-fitting,only nerve in the elbow slightly enlargement or shape change is not obvious.2.Ultrasound can be found that nerve conformity of reason:most is the hyperplastic osteophyte with joint surfaces,the other is with tendon sheath cyst,scar tissue and soft tissue mass,etc.3. In light of the heavy line of analysis of variance between the three groups, was statistically significant difference between the three groups(0.082±0.010 VS0.122±0.025VS0.225±0.092, P < 0.01). Using ROC curve respectively determine the division of light,medium and severe group threshold,mild and moderate group in the thickest cross-sectional area acuity 0.097cm2,sensitivity was 92%,specificity was 88%:Moderate group and severe group in the thickest cross-sectional area acuity 0.164cm2,sensitivity was 96%,specificity was 83%.4.The CTS patients with early postoperative ulnar nerve morphology change is not obvious.Conclusions:1.High frequency ultrasound can clearly show CTS patients with ulnar nerve morphology change,points out that the conformity of parts,clear the cause of the conformity of,provide a reference basis for surgical treatment,and to observe the nerve surrounding soft tissue lesions especially tendon sheath cyst,avoids the chance of reoperation.2.High frequency ultrasound to measure the thickest nerve cross-sectional area,and according to the measured value judge the degree of nerve damage,provide reference for clinical information.3.The high-frequency ultrasound can observe the nerve of the incision recovery,can detect surrounding nerve lesions in soft tissue regeneration,but the early evaluation of postoperative never recovery situation is not ideal.4.High frequency ultrasound is an effective method of auxiliary examination of CTS after preoperative clinical diagnostic value.
