Abstract：
UNASSIGNED: Giant cell tumors (GCT) are a relatively uncommon type of non-cancerous bone growth, representing around 4-10% of all bone tumors. These tumors tend to exhibit local aggressiveness and are typically prevalent in individuals between 20 and 40 years old. Commonly observed locations for GCT include the distal femur, proximal tibia, and the distal end of the radius. However, occurrences at the distal end of the ulna are rare, accounting for only 0.45-3.2% of cases.
UNASSIGNED: In this instance, we present the case of a 36-year-old male diagnosed with a GCT specifically located in the left distal ulna. Our approach involved managing the patient through the complete removal (en-bloc resection) of the distal ulna. Following this, we performed an extensor carpi ulnaris (ECU) tenodesis to stabilize the proximal stump. After 2-year follow-up, the patient exhibited positive outcomes, displaying satisfactory wrist joint mobility and functionality without any signs of tumor recurrence.
UNASSIGNED: This case emphasizes the effectiveness of wide resection as a viable treatment for huge GCTs in the distal ulna. Utilizing tenodesis with the tendon of ECU significantly contributes to stabilizing the ulnar stump, leading to improved wrist function.

摘要：
■巨细胞瘤（GCT）是一种相对不常见的非癌性骨生长类型，约占所有骨肿瘤的4-10％。这些肿瘤倾向于表现出局部侵袭性,并且通常在20至40岁之间的个体中普遍存在。通常观察到的GCT位置包括股骨远端，胫骨近端,和桡骨的远端。然而,发生在尺骨远端是罕见的，仅占病例的0.45-3.2%。
■在这种情况下，我们介绍了一例36岁的男性,诊断为GCT的患者特别位于左尺骨远端.我们的方法涉及通过完全切除（整块切除）远端尺骨来管理患者。在此之后,我们进行了尺侧腕伸肌（ECU）肌腱固定术以稳定近端残端。经过2年的随访,患者表现出积极的结果，显示令人满意的腕关节活动度和功能，没有任何肿瘤复发的迹象。
■该病例强调了广泛切除作为尺骨远端巨大GCT的可行治疗方法的有效性。利用肌腱固定术与ECU的肌腱显著有助于稳定尺骨残端，改善手腕功能。
