in a prospective investigation in 1984 and 1985 , all colles ' fractures ( not comminuted or intraarticular ) that redisplaced after two closed reductions were allocated at random to one of two groups : group i ( n = 23 ) , in which the dorsal bone deficiency was filled with bone cement ( methylmethacrylate ) , and group ii ( n = 25 ) , in which the fracture was treated with external fixation .
