Randomized Controlled Trial Comparative StudyVirtual surgery simulation versus traditional approaches in training of residents in cervical pedicle screw placement.
The cervical screw placement is one of the most difficult procedures in spine surgery, which often needs a long period of repeated practices and could cause screw placement-related complications. We performed this cadaver study to investigate the effectiveness of virtual surgical training system (VSTS) on cervical pedicle screw instrumentation for residents. ⋯ This study demonstrated that the VSTS as an advanced training tool exhibited promising effects on improving performance of novice residents in cervical pedicle screw placement compared with the traditional teaching methods.

Outcomes following surgical management of femoral neck fractures in elderly dialysis-dependent patients.
Proximal femur fractures are one of the most common fractures observed in dialysis-dependent patients. Given the large comorbidity burden present in this patient population, more information is needed regarding post-operative outcomes. The goal of this study was to assess morbidity and mortality following operative fixation of femoral neck fractures in the dialysis-dependent elderly. ⋯ Regardless of the surgery performed, dialysis dependence is a significant risk factor for major post-surgical morbidity and mortality after operative treatment of femoral neck fractures in this population. Increased mechanical failure in the internal fixation group was not observed. The increased risk associated with caring for this population should be understood when considering surgical intervention and counseling patients.

Comparative StudyThe femoral component alignment resulting from spacer block technique is not worse than after intramedullary guided technique in medial unicompartimental knee arthroplasty.
Although the spacer block technique has been recommended for the implantation of unicompartmental knee arthroplasty (UKA), there is still a lack of data concerning the resulting component positioning. ⋯ The spacer block technique produces results comparable to the intramedullary guided technique. However, the precision is low and outlier frequent. Due to the possibility of transferring a tibial malalignment to a femoral malalignment, even greater attention should be paid to the precision of tibial resection.

Comparative StudyComparison of volarly and dorsally displaced distal radius fracture treated by volar locking plate fixation.
In case of distal radius fractures (DRF) the distal fragment generally displaces either dorsally or volarly. Scientific literature however, seldom differentiates between volarly and dorsally displaced DRFs when reporting results. It is no clear, if the direction of displacement has an influence on the clinical and radiological outcome. This study was intended to evaluate the influence of displacement direction in adult patients with surgically treated Colles or Smith type fractures. ⋯ Decreased flexion in combination with a decreased dorsopalmar tilt might hint towards a mechanical inhibition in the Colles group. Altogether, the study showed good clinical outcome with satisfactory radiological result. As all patients showed arthrosis progression, the fracture per se is to be seen as a prearthrotic factor. It still remains unclear which measures could be taken to prevent this.
