Rupture of the triceps tendon is rare, and no previous report of its association with olecranon bursitis was found in the literature. A previously healthy 72-year-old man fell from a stationary bicycle and was examined by his family physician. Calcification over the olecranon area with an intact triceps tendon was revealed. Two months later the patient presented with triceps rupture and weakness of elbow extension with olecranon bursitis. Grossly, the pathologic lesion consisted of synovial frond proliferation and invasion of the cut end of a tendon. A "collar stud-shaped" bursa was found in front of and behind the triceps tendon and across a 3-cm gap in the tendon. The advancement was completed by splitting the tendon in partial thickness proximal to the cut end. The flap was turned down and anchored to the olecranon through drill holes. The end result was good return of function. Patients with chronic olecranon bursa problems should be carefully examined for triceps function. The gap in the tendon can be treated by mobilizing the tendon in the manner described.
肱三头肌腱断裂较为罕见，文献中未发现其与鹰嘴滑囊炎相关的既往报道。一名既往健康的72岁男性从静止的自行车上摔落，由其家庭医生进行检查。发现鹰嘴区域有钙化，肱三头肌腱完整。两个月后，患者出现肱三头肌断裂，伴有鹰嘴滑囊炎，肘关节伸展无力。大体上，病理病变包括滑膜皱襞增生和肌腱断端的浸润。在肱三头肌腱前方、后方以及肌腱上一个3厘米的间隙处发现了一个“哑铃状”滑囊。通过在断端近端将肌腱部分厚度劈开完成推进。皮瓣向下翻转并通过钻孔固定在鹰嘴处。最终功能恢复良好。对于患有慢性鹰嘴滑囊问题的患者，应仔细检查肱三头肌功能。肌腱间隙可通过上述方法活动肌腱进行治疗。
