The optimal treatment for intra-articular calcaneus fractures remains controversial, despite internal fixation techniques providing good results. The major point of contention is the need to reconstruct the overall morphology versus to restore the anatomy of the subtalar joint perfectly. We will describe a two-stage technique for treating intra-articular calcaneus fractures in which the primary...

Osteosarcoma of the foot is rare and, when presents, commonly observed in adults. We report a case of osteosarcoma of the calcaneus in an 11-year-old girl who was presented with a 4-month history of pain and swelling on her left ankle and inability to walk in her left lower extremity. On examination, there was a diffuse swelling involving her left ankle joint and foot. The radiograph showed sof...

[Purpose] Severe calcaneus misalignment is correlated with low back pain, and affects pelvic alignment. However, little has been published with regard to the influence of pronation and supination on trunk alignment. Therefore, the present study aimed to investigate the influence of calcaneal inversion on pelvic and trunk alignment. [Subjects and Methods] A 3-dimensional motion analysis system w...

Relaxation times (T(1) and T(2)) of the bone marrow protons and trabecular bone volume fraction (TBVF) in the calcaneus were measured for 100 female volunteers using a compact MRI system at 0.2 T field strength. The speed of sound (SOS) through the calcaneus was measured also for the same subjects using a quantitative ultrasound system. Both relaxation times were found to have positive correlat...
