Three-Dimensional Preoperative Planning Software for Hip Resurfacing Arthroplasty.

Three-dimensional planning of hip arthroplasty is associated with better visualisation of anatomical landmarks and enhanced mapping for preoperative implant sizing, which can lead to a decrease in surgical time and complications. Despite the advantages of hip resurfacing arthroplasty (HRA), it is considered a technically challenging procedure and associated with inaccurate implant placement. This study aimed to examine the validity, reliability, and usability of preoperative 3D Hip Planner software for HRA.

A systematic review of non-HPV prognostic biomarkers used in penile squamous cell carcinoma.

The presence of lymph node metastasis is the most important prognostic indicator for patients with penile cancer. However, predicting which clinically node negative patients will harbor lymph node metastases remains unclear. The aim of this systematic review is to provide an overview of biomarkers p53, Ki-67, and SCCAg in predicting lymph node metastasis (LNM) and cancer-specific survival (CSS) in penile squamous cell carcinoma (SCC).
