We used a visual analog scale (VAS) to assess the satisfaction after total knee arthroplasty (TKA) in a group of 108 patients (126 TKAs) with short-term to medium-term follow-up. We also used the Knee Society scoring system, Western Ontario and McMasters Universities Osteoarthritis Index (WOMAC), pain VAS, and survival analysis. A comparison between the(More)
Loose ligation of a sciatic nerve in rats (chronic constriction injury; CCI) provokes sensory, autonomic, and motor disturbances like those observed in humans with partial peripheral nerve injury. So far, it is unknown whether these motor disturbances result from (mechanical) allodynia or from damage to the motor neuron. These considerations prompted us to(More)
Arthrodesis of the ankle joint after a failed ankle prosthesis is most often demanding because of bone loss. The bone loss is also responsible for limb length discrepancy. Intramedullary nail fixation has been described to be successful for arthrodesis of the arthritic ankle joint. We report the use of the nail technique in combination with a morsellized(More)
Reconstructions of large segmental bone defects after resection of bone tumours with massive structural allografts have a high number of reported complications including fracture, infection and non-union. Our goal is to report the survival and complications of massive allografts in our patients. A total of 32 patients were evaluated for fracture, infection,(More)
Reconstructions of segmental diaphyseal bone defects with massive allografts are related to complications like nonunion and fractures. A reconstruction of these defects with a cage filled with an impacted morsellized bone graft could be an alternative. The bone graft in these cages should ideally be loaded to prevent resorption. Loading of morsellized bone(More)
INTRODUCTION Hip fractures are a leading cause of mortality and disability worldwide, and the number of hip fractures is expected to rise to over 6 million per year by 2050. The optimal approach for the surgical management of displaced femoral neck fractures remains unknown. Current evidence suggests the use of arthroplasty; however, there is lack of(More)
Loose ligation of a rat sciatic nerve (chronic constriction injury (CCI) model) provokes signs and symptoms like those observed in reflex sympathetic dystrophy (RSD) patients. Primary afferent nociceptive C-fibers seem to be involved in an afferent orthodromic as well as in an efferent antidromic manner. In this study we hypothesize that consequent to(More)
Thirty-three symptomatic scaphoid non-unions were treated by a simple, minimally invasive procedure using a percutaneous autologous corticocancellous bone graft. After an average follow-up of 3.5 years, union was observed in 29 cases. These patients had no, or mild, pain at work and an almost normal range of motion and grip strength. No progression to(More)
Large diaphyseal bone defects often are reconstructed with large structural allografts but these are prone to major complications. We therefore asked whether impacted morselized bone graft could be an alternative for a massive structural graft in reconstructing large diaphyseal bone defects. Defects in the femora of goats were reconstructed using a cage(More)
In the chronic constriction injury (CCI) model, signs and symptoms similar to those observed in reflex sympathetic dystrophy (RSD) can be induced by loosely ligating a rat sciatic nerve. Skin microcirculatory (inflammation-like) disorders may result from release of vasoactive neuropeptides at peripheral endings of antidromically acting nociceptive nerve(More)
