Ulna Olecranon Part Of Bone-Tendon Transplantation In Repairing The Rupture Of The Finger Extensor Tendon Check Point Anatomical Basis And Clinical Application

Objective Through the anatomical observation of ulna olecranon of bone-tendon and finger extensor tendon check point form,and the corresponding measurement,according to the results of the autopsy study ulna olecranon place part of bone-tendon transplantation new method for repair of finger extensor tendon check point.Methods Formalin fixed preserved fingers and elbow joint pecimens of 8 cases,using the method of gross anatomy and anatomical bservation ulna olecranon bone tendon and the finger extensor tendon check point form,using 0.02 mm vernier caliper measurement and comparison on the width of the tendons,etc.Similarity of bone-tendon basis.In March 2013-March 2015 finger extensor tendon surgery check points in 28 patients with fracture patients take ulna olecranon part of bone-tendon transplantation in repairing finger extensor tendon check points,postoperative observation of bone-tendon check point reset is good,six weeks after the needle was pulling a functional exercises.Follow-up time of about ninety days,the application Dargan function evaluation method to evaluate the therapeutic effect.Results Ulna olecranon bone-aponeurosis and finger extensor tendon check points for the extensor tendon check point,the check point of bone are the junction of cortical bone and cancellous bone.Bone blood supply is rich,transplanted cancellous bone easy to survival,bone has the similarity in two places.The thickness of the two tendons(t value 1.428.P > 0.05)has the similarity.The length and width of the test P < 0.05.Have no similarity.Clinical ulna olecranon part of bone-tendon transplantation to repair finger extensor tendon check points,postoperative follow-up of 3 months,X ray film show fracture has healed.Refers to the function good,straight fingers small strong;Dargan function assessment,Was 100%.Conclusions Take ulna olecranon in reconstruction of bone-tendon transplantation tendon check points,improve the method of suture and fixed,can push the check point osseous healing,restore physiological characteristics,finger straight to restore finger function.The operation method is simple,less cost,combination,early functional exercise reasonable can improve the curative effect,reduce and prevent the occurrence of traumatic arthritis.
