Objective To provide anatomic basis for diagnosis and treatment of tenderness in soft tissue on the lateral of elbow through exploring their anatomic structures. Methods The anatomic structures of tenderness on the lateral of elbow e.g. lateral condyle of humerus,gap of humeroradial joint,annular articular surface,Frohse bow and supinator were observed and measured in 7 specimens of upper limb. Results The common tendon of extensor of forearm and part of the initial tendon of both brachioradial and supinator were attached to the lateral condyle of humerus. The anterior wall of the gap of humeroradial joint was the fibrous stratum of capsula articularis cubiti and the lateral wall was radial collateral ligament. The annular articular surface was covered with annular ligament whose amphi was attached to the anterior and posterior edge of the lunate sinus of ulna while its proximate lateral edge to the inferior extremity of the lateral condyle of humerus by the radial collateral ligament. The origin of supinator was combined with that of extensor carpi ulnaris. Its tendon was connected to the annular ligament and the supinator crest of the ulna. The fiber of supinator went downward and outward,then circled the radius. Its attachment ended at the anterior surface of the upper 1\3 of radius. Conclusion Every tenderness in the lateral of elbow was closely related to its anatomic structure. All the features of these anatomic structures mentioned above should be considered when treating and diagnosing the pains in the lateral of elbow.
