Objective:
To investigate the efficiency of intracystic allograft fixed with bone plate and steel plate in management of long bone cyst merging pathologic fracture.
Methods:
Twelve cases of long bone cysts with pathologic fractures were treated from January 1996 to April 2002. The median dimension of the cyst on the radiograph was 3. 6 cm x 8.1 cm. We regularly revealed the sites of cysts, cut the anterior wall, got cystic membrane away, implanted allo-bone fibula, ulna or radius shafts which were defatted and deproteined. The auto-bone and the allo-bone of all cases were fixed with bone plate and steel plate; external fixation was managed for 3 weeks after operation.
Results:
All incisions achieved primary healing. All cases were followed up 2. 7 years on average. According to Capanna's standard, 9 cases completely healed, 3 cases basically healed, no cases recurred. The function in shoulder joint was slightly limited in 2 cases that cysts were located on the upper humerus, while that of the other 10 cases were recovered completely.
Conclusion:
Intracystic allograft fixed with bone plate and steel plate is safe and effective in management of long bone cyst merging pathologic fracture.
