Outline of Final Research Achievements

45 trigger fingers with PIP joint contracture from 41 patients treated by ulnar slip superficialis tendon resection were reviewed. The mean follow-up period was 12 months. We evaluated the preoperative and postoperative grip strength (GS), PIP joint flexion (Flex), and extension angles (Ext), and DASH scores of each finger. Tendon proximal phalanx axial area ratios at the proximal 20% region (Ratio) compared with age and sex-matched control were also calculated from the CT images. The 2 groups were compared using the Student t-test.
Postoperatively, GS was 85.6% of the unaffected side compared with 63.3% preoperatively, and the Flex improved to an average of 92.8° compared with an average of 81.9° preoperatively (p<0.05). The Ext improved to -8.4° compared with an average of -25.1° preoperatively (p<0.05). The DASH scores improved from an average of 31.1 points to 15.5 (p<0.05). On CT imaging, the preoperative Ratio was significantly larger, with a healthy Ratio of 161% (p <0.05).

Academic Significance and Societal Importance of the Research Achievements

通常A1腱鞘切離・切除術が行われているPIP関節屈曲拘縮を伴う弾発指例は、手術成績が不良である例が多いことが知られている。病態としてFDSの肥厚があり、A1腱鞘のみならず、A2腱鞘間との、滑走障害が起こっているため、従来の方法では屈曲拘縮と疼痛がが残存しやすく、浅指屈筋腱尺側半腱切除術が有効と考えられた。
