The operative treatments of intra-articular calcaneal fractures with malunion / 中华骨科杂志

ABSTRACT

Objective To discuss three methods to treat intra-articular calcaneal fractures with malunion, and to investigate the indications and significances of the operative treatment. Methods From June 2002 to March 2004, 28 intra-articular calcaneal fractures with malunion patients (26 males and 2 females, 30 feet) suffered operations. The average age of these patients was 39.2 years old (range, 23-59 years). The malunion happened at left feet in 15 patients, right feet in 11, and bilateral feet in 2. The mean duration between injury and operation was 3.3 months (range, 2-5 months). All cases used improved "L" incisions at lateral of heels. 13 patients (14 cases) did open reduction and internal fixation; 9 patients (10 cases) operated calcaneal osteotomy to reserve subtalar joint and correct deformity with apophysis excision, then used internal fixations; 6 patients (6 cases) used correct deformity with apophysis excision, calcaneal cumulus reconstruction and subtalar arthrodesis. The calcaneal lateral and axial X-ray and CT films were got to measure the B?觟hler angle, Gissane angle, calcaneal width and axial length, and height of calcaneal body-thalamic portion before and after operation. There were siginificant differences at all index before and after operation(P
