• There is little evidence that dermal graft placement produces results superior to discectomy, alone. Dermis does not assume a biconcave shape and does not prevent condylar erosion after discectomy. Dermal grafting does no prevent intraarticular adhesion formation.
  • Interpositional dermis can decrease joint noise after discectomy. No clinical evidence of joint sounds such as crepitus was found in 33 of 35 operated joints evaluated an average of 2 years after discectomy with placement of a dermis interpositional graft. Dermis grafting has no effect on pain response, range of motion or the incidence of regressive condylar remodeling following discectomy.
