BACKGROUND Fractures in the distal tibial metaphysis are more complicated to treat than diaphyseal fractures. We compared treatment with plating to treatment with shorted intramedullary (IM) nailing. METHODS Patients with AO type 43A fractures were treated with plate fixation (group A, n=14) or shortened IM nailing (group B, n = 13). We compared(More)
Various surgical procedures have been described for the treatment of complete acromioclavicular joint dislocation, but no consensus exists on the optimal therapy. The aim of each type of procedure is to stabilize the clavicle by substitution of the ruptured coracoclavicular ligaments. Treatment modalities have changed with increasing understanding of the(More)
OBJECTIVE To investigate the effects of intraarticular hyaluronic acid (HA) (Artzal, Seikagaku Corp., Japan) in geriatric participants with unilateral knee osteoarthritis (OA). METHOD This was a prospective, observer-blind study with 6 months follow-up done in the setting of an outpatient rehabilitation department in a university-affiliated tertiary care(More)
OBJECTIVE To investigate the efficacy, safety and the duration of treatment effectiveness of intra-articular hyaluronic acid (Artz, Japan) in patients with ankle osteoarthritis (OA). METHOD As a prospective clinical trial, 93 patients with unilateral ankle pain for at least 6 months and radiographically classified as Kellgren-Lawrence grade I or II ankle(More)
BACKGROUND The purpose of this study was to determine the efficacy of plain magnetic resonance imaging (MRI) and magnetic resonance (MR) arthrography for detecting collateral ligamentous injury of the ankle joint. METHODS Fifty patients (October 2001 to November 2003) suffering from ankle disability who underwent plain MRI and MR arthrographic studies(More)
BACKGROUND Ankle arthritis can cause substantial pain and functional limitation. Previous studies have indicated that five weekly intra-articular injections of hyaluronate were safe and effective in the treatment of ankle osteoarthritis. The purpose of this study was to evaluate the effect and safety of three weekly injections of hyaluronate in patients(More)
Viscosupplementation refers to the concept of synovial fluid replacement with intra-articular injections of hyaluronic acid (HA) for the relief of pain associated with osteoarthritis (OA). 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)
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. METHODS This was a prospective, randomized, assessor-blinded study with a 6-month follow-up(More)
Hallux valgus is a lateral deviation of the proximal phalanx of the first metatarsophalangeal joint. It is a common disorder in adults. The etiologic factors include modern shoes, rheumatoid arthritis, pes planus, metatarsus primus varus, and trauma. Tumors causing hallux valgus deformities are unusual. We report a 50-year-old female with a hallux valgus(More)
UNLABELLED This study presents a new computer-assisted surgical planning and simulating system that employs a multimedia environment for calcaneal osteotomy surgery. The system uses a full-scale computer-assisted engineering technique for designing and developing preoperative planning modules. The planning system not only presents a real-sized 3-dimensional(More)
