Abstract：
METHODS: Two competitive athletes with isolated comminuted trapezium fractures, sustained during American football and rugby, presented with pain and swelling of the first metacarpal base. Computed tomography confirmed isolated comminuted trapezium fractures. Arthroscopic reduction of displacement with screw fixation below the articular surface was performed through a small incision. Both patients returned to their preinjury sports levels within 2 months postoperatively.
CONCLUSIONS: Arthroscopic treatment of isolated comminuted trapezium fractures achieved accurate reduction of articular surface displacement and preserved trapeziometacarpal joint stability with minimal soft-tissue invasion. This facilitated an early return to contact sports for the affected athletes.

摘要：
方法：两名具有孤立性粉碎性梯形骨折的竞技运动员，在美式足球和橄榄球期间持续，表现为第一掌骨基部疼痛和肿胀。计算机断层扫描证实了孤立的粉碎性梯形骨折。通过小切口进行关节镜下移位复位，螺钉固定在关节面以下。两名患者在术后2个月内恢复到受伤前的运动水平。
结论：关节镜下治疗孤立性粉碎性梯形骨折能准确地减少关节表面位移，并保持梯形掌骨关节的稳定性，同时软组织侵犯最小。这有助于受影响的运动员早日恢复接触运动。
