鏡視下バンカート修復術における新しい重層固定法の試み
--Easy DAFF--

抄録

There have been studies on the application of DAFF as a fixation method to replace conventional fixation techniques. DAFF strengthens the initial fixation of the Bankart region, and this method is also useful for its anatomical repair. Theoretically, better outcomes can be expected by DAFF compared to conventional methods, but it has been reported that the DAFF procedures are more complicated, and require skilled techniques. In this study, we modified the DAFF procedures, and propose knotless relayless DAFF (Easy-DAFF). The subjects were 24 males (26 shoulders) with injury related to sports.
The events consisted of basketball in 8 patients, skiing in 7, soccer in 6, American football in 3, and wrestling in 2. 1) The reduced position of the articular labrum-IGHL complex was maintained by the modified TOTS method. 2) Medial anchor: A knotless anchor with 2 loops was penetrated through IGHL at the scapular neck on the medial side. 3) Lateral anchor: 2 loops were individually fixed to the edges of the scapular joint surface to form a V shape using the knotless anchor. 4) If necessary, procedures 2) and 3) were repeated. 5) A W shape was created by performing these procedures twice. There was no subluxation nor redislocation during follow-up observation periods of more than 10 months. The mean pre-and post operative JSS scores were 50 and 89, respectively, showing improvement. Pre operative Rowe score was 19.2 and post operative score was 84.8.
