This follow-up study was designed to investigate about the results of 34 patients which were suffered from the dislocated intra-articular os calsis fracture. Their age and period of treatment were from 24 years old to 73 years old, average 44 years old, and from I year to 10 years and 8 months, average 4 year, respectivily.
Among 34 cases, 15 cases were treated by the operative reposition and 3 cases were treated by the wire traction, but remains were not treated any repositive procedure. Almost all cases which the adaptation of posterior talo-calcaneal joint surface wrer recovered completely, showed excellent results, but the results of insufficient cases were same comparing with the results of the group which was not treated by orthopaedic reposition.
The Böhler angle showed the good indicator to judge the recovery of adaptation of the posterior talo-calcaneal joint surface except for depression type fracture. Comparing with the group not tried reposition, the group tried reposition showed markedly good results. This study suggested that the reduction of mobility of the talo-calcaneal joint caused to deteriorate the results and the period of fixation was better within 8 weeks.
