Abstract

Purpose: The accessory bones around the elbow are very rare variant structures, present in approximately 0.7% of cases. They can cause diagnostic problems and can be mistaken for pathological structures, especially when pain and limitation of elbow movements are present and a trauma can be traced in the patient's history. They are of different nature, either presenting within muscle tendons as sesamoids (brachialis and triceps brachii muscles) or presenting intra-articularly probably as separated or accessory ossification centres. The least common is the os supratrochleare anterius.

Methods: We present a case of a young male, featuring chronic blocking and 20° limited flexion of his right elbow, which bothered him during his occupation as a locksmith. In history, he suffered minor trauma to the elbow 20 years ago. X-ray and CT showed a large ossicle in the coronoid fossa of the humerus.

Results: The ossicle was surgically extracted in small pieces. The patient left satisfied with no mention of complaints.

Conclusion: The os supratrochleare anterius is a very rare accessory bone of the elbow, located in the coronoid fossa of the humerus which can mimic many pathological states, and limit movements and causing pain around the elbow.

踝上畸形：一个非常罕见的临床病例和文献综述。

目的：肘部周围的附属骨是非常罕见的变异结构，约占病例的 0.7%。它们可能会造成诊断上的困难，也可能被误认为是病理结构，尤其是当患者出现疼痛和肘部活动受限，并且在病史中可追溯到外伤时。它们的性质各不相同，有的在肌腱内表现为芝麻状突起（肱肌和肱三头肌），有的在关节内表现为分离的或附属的骨化中心。最不常见的是腕上髁前骨化：我们介绍了一例年轻男性的病例，他的右肘长期受阻且屈曲受限 20°，这在他从事锁匠职业期间一直困扰着他。20年前，他的肘部曾受过轻微外伤。X 射线和 CT 显示，肱骨冠状窝内有一个大骨赘：结果：通过手术将骨块切成小块。患者满意离院，未提及任何不适：肘前上骨是一种非常罕见的肘部附属骨，位于肱骨冠状窝内，可模拟多种病理状态，限制活动并引起肘部疼痛。

期刊介绍： Anatomy is a morphological science which cannot fail to interest the clinician. The practical application of anatomical research to clinical problems necessitates special adaptation and selectivity in choosing from numerous international works. Although there is a tendency to believe that meaningful advances in anatomy are unlikely, constant revision is necessary. Surgical and Radiologic Anatomy, the first international journal of Clinical anatomy has been created in this spirit. Its goal is to serve clinicians, regardless of speciality-physicians, surgeons, radiologists or other specialists-as an indispensable aid with which they can improve their knowledge of anatomy. Each issue includes: Original papers, review articles, articles on the anatomical bases of medical, surgical and radiological techniques, articles of normal radiologic anatomy, brief reviews of anatomical publications of clinical interest. Particular attention is given to high quality illustrations, which are indispensable for a better understanding of anatomical problems. Surgical and Radiologic Anatomy is a journal written by anatomists for clinicians with a special interest in anatomy.
