Abstract:
BACKGROUND:Bone graft for acetabular reconstruction includes morselized bone graft, structural bone graft and hybrid bone graft, and the morselized bone has been widely used because of the advantages of simple
production and short healing time.
OBJECTIVE:To explore the key technologies and clinical effect of impaction bone grafting with morselized bone in total hip revision for AAOS Ⅲ acetabular deficiency.
METHODS:Sixteen cases of AAOS Ⅲ acetabular deficiency were treated with impaction bone grafting with morselized bone combined with metal devicesor constructive bone grafting. The hip Harris scores and
radiographic data were compared before and after treatment. The effect of impaction bone grafting with morselized bone on acetabular deficiency was assessed.
RESULTS AND CONCLUSION:Al the patients were fol owed-up at 3, 6, 12 months after surgery and every half a year successively. The pain of hip joints after operation was relieved significantly and the walking function was
restored. The hip Harris score was improved from 48.00 points before surgery to 84.94 points after surgery (P<0.01). Five cases were graded as excel ent, eight cases as good, two cases as average, and one case as poor. The excel ent and good rate was 81%, and the satisfying rate of the patients was 94%. The post-operative X-ray films of al the 16 patients showed that the acetabular rotation centers were recovered (near) to normal and the acetabular cups were covered wel by bone. The grafting bone particles got radiological osseointegration and the
acetabular cup prosthesis did not displaced, and no displacement and breakage happened to the metal devices.
Impaction bone grafting with morselized bone in total hip revision for AAOS Ⅲ acetabular deficiency can effectively reconstruct the acetabular bone structure, retain and restore the acetabular bone mass, and it has good technical advantages and good clinical effects.
