BACKGROUND Retrograde intramedullary nailing is an established technique for tibiotalocalcaneal arthrodesis (TTCA). In poor bone stock (osteoporosis, neuroarthropathy), device fixation in the hindfoot remains a problem. Fixed-angle spiral-blade fixation of the nail in the calcaneus could be useful. MATERIALS AND METHODS In seven matched pairs of human(More)
BACKGROUND The aim of this study was to investigate the potential clinical benefit of tibiotalocalcaneal arthrodesis (TTCA) with an intramedullary nail with a valgus curve, two compression options, and angle-stable locking. MATERIAL AND METHODS Patients who had undergone TTCA at two tertiary hospitals were eligible. Patients who had undergone TTCA before(More)
BACKGROUND Constrained functionality and phantom limb pain (PLP) are major concerns for forearm amputees. Neuroscientific investigations of PLP suggest that behaviorally relevant stimulation of the stump can decrease PLP. Furthermore the prosthesis user could use feedback information of the prosthesis hand for optimizing prosthesis motor control when(More)
Despite the improvement in surgical technique and implant design in orthopedic and trauma surgery, implant-related infections are still a challenging problem for surgeons. The use of local prophylaxis to avoid infection, such as antibiotic-loaded cement in arthroplasty, gentamicin PMMA beads and gentamicin-collagen sponge in trauma surgery, and(More)
AIM The aim of this study was to evaluate the progression of osteoarthritis (end-stage disease with a requirement for arthroplasty) in patients with focal cartilage defects of the medial knee compartment. MATERIAL AND METHODS Patients (n = 115) with focal cartilage lesions of the medial knee compartment underwent arthroscopy. The follow-up was performed(More)
OBJECTIVE This study investigates whether early dynamic positron emission tomography/computed tomography (edPET/CT) using (18)F-sodium fluoride-((18)F-NaF) is feasible in depicting early phases of radiotracer distribution in patients with chronic osteomyelitis (COM). METHODS A total of 12 ed(18)F-NaF-PET/CT examinations were performed on 11 consecutive(More)
BACKGROUND Noninvasive diagnosis continues to present a challenge in chronic bone infections. Positive intraoperative microbiological and/or histological results are regarded as the gold standard for confirmation of the diagnosis. The aim of the present study was to evaluate the value of F-18 FDG-PET in the diagnosis of chronic osteitis in the patients of a(More)
BACKGROUND In the last years intramedullary nailing has become the treatment of choice for most displaced diaphyseal tibia fractures. In contrast intramedullary nailing of distal tibia fractures is accompanied by problems like decreased biomechanical stability. Nevertheless the indications for intramedullary nailing have been extended to include even more(More)
AIM Vacuum-assisted closure is used frequently for the treatment of skin and soft-tissue infections (SSTI) of the extremities. After debridement and repeated VAC dressing changes, the wounds are closed by secondary suture, split-thickness skin grafts or local flaps. However, no objective parameters describe the time point for secondary wound closure. Our(More)
Damage to hyaline cartilage is the most important pathophysiological tool in the development of osteoarthritis. Cartilage lesions are the most frequent pathological findings during arthroscopic operations. Arthroscopies as well as magnetic resonance tomography are gold standards for(More)
