Scapholunate ligament reconstruction using a bone-retinaculum-bone autograft: A biomechanic and histologic study

Chronic Scapholunate Ligament Injury

“…The third metacarpal to capitate ligament or a segment of bone and retinaculum from the region of the Lister tubercle also can be used. [38][39][40][41][42][43][44] Delayed graft healing and pullout from the scaphoid and lunate are complications associated with bone-tissue-bone reconstruction. Because of these complications, thought to be attributed to failure of osseous ingrowth, a vascularized graft of third metacarpal-capitate, based on the radial-sided intermetacarpal artery was designed.…”

“…37,40 Proponents of this technique suggest that bone-to-bone healing may be more predictable than ligamentto-bone healing. Pitfalls associated with bonetissue-bone grafts include (1) stretch of the tissue portion of the graft over time, (2) failure of the graft to incorporate because of a tenuous proximaldorsal blood supply of both the scaphoid and lunate, and (3) failure to address the rotatory subluxation of the scaphoid in static dissociation.…”

Bone-Retinaculum-Bone Autografts for Scapholunate Interosseous Ligament Reconstruction

“…These interventions include, but are not limited to, primary repair of the ligament; capsulodesis; tenodesis; screw fixation; limited arthrodesis; and a variety of ligament reconstruction techniques, including bone-soft tissue-bone ligament reconstruction. [2][3][4] There is general dissatisfaction with the outcomes following primary repair of an acute SLIL tear; there is even more controversy regarding the treatment of chronic tears of the SLIL. 2 No technique to this date has proved to provide optimal results.…”

“…2 The need for a surgical technique that provides lasting pain relief, normalized wrist kinematics, and decreased incidence of SLAC wrist degenerative changes is evident. 3 Based on the use of bone-patellar tendon-bone autograft for anterior cruciate ligament reconstruction of the knee, Weiss 4 described the use of bone-retinaculumbone (BRB) autograft for the treatment of SLIL injuries.…”

Die Behandlung der veralteten skapholunären Dissoziation mittels eines Knochen-Band-Knochen-Transplantats nach Cuénod

“…Svoboda et al [15] untersuchten an Leichenpräparaten Knochen-Band-Knochen-Transplantate vom Fuß auf ihre Eignung als Ersatz des dorsalen skapholunären Bandanteils; später folgten Davis et al [6] und Hofstede et al[11] auf diesem Weg. Shin et al[14] strebten dagegen ein lokal verfügbares Transplantat an und befanden ein KnochenPeriost-Knochen-Transplantat, das aus der Region des Lister-Tuberkels gehoben wurde, als geeignet, obwohl es nicht die mechanische Stabilität des originären skapholunären Bandanteils hatte. Dieses Knochen-…”
