- W2977718947 abstract "Objective To investigate the long term X ray photography manifestation after transplantation of frozen allogenic phalanx and joint. Methods 276 cases of thumb and finger reconstruction were performed using composite tissue transplantation of frozen allogenic phalanx joint tendon sheath ,combined with wraparound flap transfer. 208 cases were involved in the study and they were randomly divided into 6 subgroups: 2 6 months,7 12 months,13 24 months,3 5 years,6 10 years and over 10 years, with each group greater than 20 cases .Comparison of X ray manifestation was performed. Results Bone union between the allograft and autograft occurred 76.92% at postoperative 6 month group, 94.29% at 12 months group, 98.21% at 10 years group, respectively . However, there was gradual deterioration of degeneration and bone absorption around sub joint area and joint surface, with bone absorption rate from 7.69% at 6 months group to 64.29% at 10 years group, and with joint degeneration from 3.85% to 85.71% . Bone absorption and joint degeneration decreased at over 10 years group. The overall bone union rate was 94.23% in 208 cases, while bone absorption in sub joint area and the finger tip was 39.42%, and joint degeneration rate 51.44%. Conclusions Transplantation of frozen allogenic phalax and joint can make union with autogenous bone, with an identical healing process of roentogenographic demonstration comparing with autogenous bone transplantation. However, gradual deterioration of allo cartilage degeneration and necrosis, as well as sub joint bone absorption occurred with aggravation at an increasing rate after operation." @default.
