This study examined whether radiofrequency electrothermal treatment of thumb basal joint instability could produce clinical improvement and result in successful functional outcomes for patients.
From August 2001 to April 2006, we treated 17 thumbs with symptomatic thumb basal joint instability using arthroscopic electrothermal shrinkage of the volar ligaments and joint capsule with a monopolar radiofrequency probe. The sample included 11 men and 6 women with a mean age of 35.3 years (range, 20 to 60 years). All patients underwent regular clinical follow-up at a mean of 41 months (range, 24 to 80 months).
Pain improved in all thumbs after surgery. Thumb pinch strength significantly improved in all thumbs after surgery (P < .01). All patients were satisfied with the results and returned to their preinjury activities.
By use of the described method of arthroscopic electrothermal shrinkage of the volar ligaments and joint capsule in patients with symptomatic thumb basal joint instability, most patients had good subjective results and the pinch strength improved significantly in most patients. Of 17 thumbs, 16 had satisfactory subjective and functional stability at a minimum 2 years' follow-up.

本研究旨在探讨射频电热疗法治疗拇指掌指关节不稳是否能改善临床症状并使患者获得成功的功能预后。
2001年8月至2006年4月，我们采用单极射频探头对17例有症状的拇指掌指关节不稳患者进行关节镜下电热收缩掌侧韧带和关节囊治疗。样本包括11名男性和6名女性，平均年龄35.3岁（范围20至60岁）。所有患者平均随访41个月（范围24至80个月）。
术后所有拇指疼痛均有改善。术后所有拇指的捏力均显著提高（P <.01）。所有患者对结果满意并恢复到伤前的活动水平。
对于有症状的拇指掌指关节不稳患者，采用所述的关节镜下电热收缩掌侧韧带和关节囊的方法，大多数患者主观结果良好，大多数患者的捏力显著提高。在17例拇指中，16例在至少2年的随访中主观和功能稳定性令人满意。
IV级，治疗性病例系列。
