PURPOSE We report complications occurred from 6 patients among 14 patients who received the operation for their radial head and neck fractures by using the absorbable rod made by poly-glycolic acid(PGA). MATERIALS AND METHODS We analyze the postoperative results of 14 patients who recieved fixation by absorbable rod for the radial head and neck fractures from March 1991 to March 2000. All of the fractures were are reducible and modified Mason 's type II. RESULTS After average 15 months follow up, flexion contracture was average 20 degrees and full flexion was average 130 degrees. Complications were occurred in 6 cases. Osteolysis was occurred in 3 cases and in 2 cases among theses 3 cases, radial head excision was performed. Synovitis was occured in other 3 cases and in one case joint fluid was drainaged from operation wound for 2 weeks and in other 2 cases, synovitis was progressed to arthritis. CONCLUSION The absorbable rod made of PGA in radial head and neck fracture have relatively high rate of adverse tissue responses. So surgeon should consider adverse tissue response of PGA. Development of more biocompatible absorbable and slow degrading material should be needed.
Posterior hip dislocation with femoral head and neck fracture(Pipkin type III) was considered as a rare injury, However, the advance of high speed motor vehicle accidental injury has contributed to its increased incidence and the choice of treatment is still controversial.
Mechanism of injury was considered as a kind of secondary trauma of inversion or internal rotation force with hip joint was flexed position state. Three cases of posterior hip dislocation with femoral head and neck fracture(Pipkin type III)have been experienced and follow up still now at Soon Chun Hyang University hospital. The results were evaluated by Thomson Epsteins clinicoradiologic criteria and Harris hip score and follow up radiologic findings.
As a results of this study, we are more prefer primary open reduction and rigid internal fixation than primary joint replacement arthroplasty due to be occured in young age group. And futher evaluation should be needed.
