Lumbar lordosis and sacral slope in lumbar spinal stenosis: standard values and measurement accuracy.
Radiological study. ⋯ Manual measurement of LL and SS in patients with LSS on lateral radiographs is easily performed with excellent intra- and interobserver reliability. Correlation between LL and SS is very high. Differences between patients with and without previous decompression were not statistically significant.

The feasibility of endoscopically assisted decompression of the superficial radial nerve at the midportion and distal forearm was assessed. ⋯ The endoscopically assisted release of the superficial radial nerve may be feasible in a safe and sufficient way.

Surface or full cementation of the tibial component in total knee arthroplasty: a matched-pair analysis of mid- to long-term results.
Despite the clinical success of cemented TKA, aseptic loosening of the tibial component remains a potential long-term complication. Considering the constantly growing revision burden, there is a need for clarification regarding controversial views on primary fixation techniques. In this retrospective analysis, surface (SC) or full cementation (FC) of tibial components was compared in a matched-pair and long-term setting. ⋯ Results of this study showed no statistically significant difference regarding long-term survivorship for the two cementing techniques. This finding questions the claimed advantage of full cementation for tibial components. The presented data do not support the concern that surface cementation results in insufficient fixation in patients with rheumatoid arthritis.

Three-dimensional virtual simulation and evaluation of the femoroacetabular impingement based on "black bone" MRA.
Femoroacetabular impingement (FAI) is a recognised cause of secondary osteoarthritis of the hip. Several imaging methods have been used to analyse the pathologic signs. Because of the lack of precise pre- and intraoperative overview and the difficulty locating osseous pathologies, arthroscopic and minimal invasive treatment is still challenging, even for trained surgeons. This paper describes a procedure that is based on magnetic resonance arthrography (MRA) and is used to virtually verify the range of motion (ROM) of the hip. It enables the evaluation of FAI and the preoperative simulation of adequate surgical manoeuvres. ⋯ The described procedure is a useful tool for the preoperative investigation of impinging hips. It enables appropriate planning of required surgical interventions.

Prevention of excessive postoperative sliding of the short femoral nail in femoral trochanteric fractures.
Lag screw cut-out is one of the major postoperative complications on femoral trochanteric fractures. However, precise analyses of excessive sliding and lag screw cut-out were limited. The purpose of this study was to investigate the factors that induce this unfavorable event. ⋯ Because the sliding distance increased in the intramedullary type in the lateral view of unstable fractures, an accurate reduction in the lateral view at surgery is important, particularly in unstable fractures.
