Currently,surgical treatments in tennis elbow include open,arthroscopic and percutaneous procedures.Open surgery,having definite curative effects,is commonly used.There are different surgical methods based on different hypotheses about the pathogenesis of tennis elbow,such as detachment of common extensor origin,resection of annular ligament,denervation surgery and resection of microvascular nerve bundle.There is a huge difference in open surgery of tennis elbow between China and abroad.Debriding or releasing extensor carpi radialis brevis and common extensor tendon are mostly used abroad though it remains controversial whether we should release or debride with tendon,as well as whether it is better to decorticate on lateral epicondyle or not.In China,tennis elbow is treated with resection of microvascular nerve bundle except for debridement and release of tendon.As for evaluation criteria,the following methods,grip strength,grading system and visual analogue scale have been used in researches.However,cure rate and response rate are valuation criteria for resection of microvascular nerve bundle in China.The evaluation criteria are different among various surgical methods,even in the methods,especially for grading system.Each research has unique standards to define excellent,good,fair and poor outcomes.Complications of tennis elbow open surgery are rare,while subcutaneous hematoma is the common complication.

Objective: To explore the effect of anterior alveolar bone reconstruction achieved through autogenous block bone from the wisdom teeth extraction zone in onlay grafting technique. Methods: The 20 patients with bone defect of anterior teeth area were selected. They all had impacted teeth with no infection factors of pericoronitis to be removed. They were treated with autogenous block bone grafts from wisdom teeth extraction zone in onlay grafting technique respectively. The changes of thickness and the height of the bone measured from CBCT before and after 6 months of the surgery were carefully compared. Questionnaire from the patients opinion of acceptance was also be collected. Results: Acceptance questionnaire showed an average score of 55 points (60 full score). Among them, 75% of paitients showed totally supportion and 25% showed basically supportion. The thickness was 6.73 ± 0.28 mm after the surgery compared with 2.26 ± 0.57 mm before the surgery which illustrated a significant difference (F = 6.32, P<0.001). The height didn't change obviously before 14.32 ± 0.31 mm and after 14.56 ± 0.35 mm the surgery. The technique of using autogenous block bone from the wisdom teeth extraction zone improved the compliance of patients with surgery. It can provide good osteogenesis effect and solve other oral diseases at the same time. Conclusion The Onlay grafting technique which using autogenous block bone from the wisdom teeth extraction zone was a simple and effective techniques for anterior alveolar bone augmentation.
