The lateral collateral ligament complex is the key structure involved in recurrent elbow instability. Treatment is surgical, by repair or reconstruction of the lateral collateral ligament complex. We evaluated the effect of arthroscopic electrothermal shrinkage for treatment of chronic posterolateral rotator elbow instability.
21 patients, median age 32 (24-50) years, suffering from chronic lateral elbow instability underwent arthroscopic electrothermal ligament shrinkage with a bipolar shrinkage probe. All patients were available for follow-up after median 30 (8-48) months.
No complications were seen. The Morrey score increased from 40 to 77 points. The result was moderate (50-80 points) in 10 patients, and in the other patients a good result was achieved (80-95 points). The manual stress radiography showed a mean lateral joint opening of 13 (8-18) mm preoperatively. During follow-up, it decreased to 2 (1-4) mm.
Our findings suggest that arthroscopic bipolar ligament shrinkage is sufficient for the treatment of chronic posterolateral rotator elbow instability.
外侧副韧带复合体是复发性肘关节不稳定所涉及的关键结构。治疗方法为手术治疗，即修复或重建外侧副韧带复合体。我们评估了关节镜下电热收缩术治疗慢性后外侧旋转型肘关节不稳定的效果。
21例慢性肘关节外侧不稳定患者，中位年龄32（24 - 50）岁，使用双极收缩探头进行关节镜下电热韧带收缩术。所有患者在中位随访30（8 - 48）个月后均可供随访。
未见并发症。Morrey评分从40分提高到77分。10例患者结果为中等（50 - 80分），其他患者取得了良好结果（80 - 95分）。手法应力X线片显示术前外侧关节平均开口为13（8 - 18）mm。随访期间，该值降至2（1 - 4）mm。
我们的研究结果表明，关节镜下双极韧带收缩术足以治疗慢性后外侧旋转型肘关节不稳定。
