[Purpose] The purpose of this study was to clarify the stabilizing effect of Caspari's technique for anterior shoulder instability with MDI.
[Materials and methods] We retrospectively studied 18 patients (7 males and 11 females) with anterior shoulder instability with inferior and multidirectional laxity who underwent a Caspari technique. The mean age was 23 years old, and the mean follow-up period was 3 years and 8 months. There were three additional procedures; an inferior capsular shift (method-C), reinforced with a subscapularis tendon (method-S), and rotator interval closure (method-R).
[Results] In the Rowe scoring system, there were 17 excellent and good for and one poor. Both inferior and posterior laxity had improved in all the cases. Anterior laxity had improved in 14 (78%) at abduction 30°,17 (94%) at abduction 90°. There was a residual anterior laxity in the method-C group at low abduction, while in the method-S group, laxity had improved in all directions.
[Conclusion] Caspari's technique was effective for stabilization for anterior
shoulder instability with MDI. Caspari's technique reinforced with a subscapularis was thought to be reliable.
