Intra-articular viscosupplementation was approved by the Food and Drug Administration (FDA) in 1997. It is currently indicated only for the treatment of pain associated(More)
OBJECT The purpose of this study was to evaluate the effectiveness of coralline hydroxyapatite (CHA) and laminectomy-derived bone as an adjuvant graft material when combined with autogenous iliac bone graft (AIBG) in posterolateral fusion (PLF). METHODS This prospective, case-control study involved 58 patients who underwent lumbar(More)
BACKGROUND There was an increasing requirement for novel treatments of osteoarthritis (OA). The aim was to compare the efficacy of intraarticular Botulinum toxin type A (BoNT-A) and intraarticular hyaluronate plus rehabilitation exercise in patients with ankle OA.

In this study, we developed a CT-based computer-assisted pre-operative planning and simulating system for the calcaneal osteotomy by integrating different software's function. This system uses the full-scaled 3D reverse engineering technique in designing and developing preoperative planning modules for the calcaneal osteotomy surgery. The planning system(More)
