Avascular necrosis of the lunate bone (Kienböck disease) is caused by loss of blood supply of the bone. This study aimed to evaluate the efficacy and safety of a novel nickel-titanium (Ni-Ti) memory alloy arthrodesis concentrator in the treatment of this disease.A consecutive 24 patients with stage IIIb aseptic lunate necrosis were treated with scapho-trapezio-trapezoeid (STT) arthrodesis using...

INTRODUCTION Arthrodesis of the ankle is an established operation. The lack of normal ankle movement after ankle arthrodesis reduced the ability of the patients to walk smoothly on the arthrodesis foot. It would have a more profound effect in negotiating stairs, because large ranges of dorsiflexion and plantarflexion are required to accomplish this activity. Although gait characteristics have b...

Purpose. The purpose of this study was to compare the oncologic, reconstructive and functional outcomes of patients who underwent osteoarticular allograft reconstruction with those who underwent arthrodesis for a primary malignant bone tumour of the proximal humerus.Patients. Eleven patients were treated with osteoarticular allograft reconstruction of the proximal humerus. Five of these reconst...

The hypothesis of this study was that arthrodesis of the thumb interphalangeal joint at a degree of flexion greater than the recommended 0° to 15° in the era of widespread use of handheld devices would potentially be more beneficial for the use of these devices. For patients who rely heavily on a smart-phone or handheld device and require dominant thumb arthrodesis, thumb interphalangeal arthro...

STUDY DESIGN Retrospective study. PURPOSE To evaluate the relationship between a new osteoporotic vertebral fracture and instrumented lumbar arthrodesis. OVERVIEW OF LITERATURE In contrast to the growing recognition of the importance of adjacent segment disease after lumbar arthrodesis, relatively little attention has been paid to the relationship between osteoporotic vertebral fractures an...

Conversion of knee arthrodesis to total knee arthroplasty is a difficult procedure accompanied by many complications due to soft tissue and extensor mechanism contracture and bone defects. We report two cases of distal femur osteosarcoma that had been undergone wide resection arthrodesis initially. Arthrodesis was converted to total knee arthroplasty with hinged prosthesis after many years. We ...

BACKGROUND A variety of metacarpophalangeal joint (MCPJ) arthrodesis techniques have been described for the treatment of symptomatic arthritis and instability of the thumb MCPJ including K wire fixation, tension-band arthrodesis, plate fixation, intramedullary screw, and other intramedullary devices. This study presents a retrospective review of one surgeon's initial series of patients undergoi...

Arthrodesis of the wrist has been considered as the gold standard for osteoarthritis of the wrist. In 1984 Watson and Ballet identified a specific pattern of carpal collapse (scapholunate advanced collapse = SLAC) with progressive osteoarthritis. In order to preserve some motion, other alternative procedures have been proposed: proximal row carpectomy (PRC) and scaphoidectomy combined with a fo...

Depending upon initial treatment, between 2 and 30% of patients with a displaced intra-articular calcaneal fracture require a secondary arthrodesis. The aim of this study was to investigate the effect of subtalar versus triple arthrodesis on functional outcome. A total of 33 patients with 37 secondary arthrodeses (17 subtalar and 20 triple) with a median follow-up of 116 months were asked to co...
