Running is possible after hip resurfacing, and runners can even return to some level of competition, but this short follow-up series of hip resurfacing in athletes should be interpreted with caution regarding implant survival.

In our series, GUEPAR II total joint arthroplasty of the thumb CMC joint has proven to be efficacious, improving motion, strength, and achieving a high degree of pain relief. Successful outcome appears in our experience contingent upon strict compliance with numerous surgical technique details. Current research focuses on improving bipolar fixation by developing press-fit cementless implants.

The LFCN can be seen in the groin with the aid of sonography.

Intrapelvic acetabular cup migration is a rare but serious complication, which can occur after cup loosening following total hip arthroplasty. To make safe intrapelvic implant removal, several principles must be respected: identification of potential risks with a thorough preoperative workup, preoperative planing of a surgical strategy for removing protruding hardware without injuring noble anatomical structures, preserving muscle and bone stock, pelvic anatomy reconstruction (including, as needed, osteosynthesis of the pelvis), and prosthetic components selection correcting any length discrepancy. Preoperative assessment is based on a complete radiological workup, angio-CT, as well as studies searching for signs of inflammation (blood workup and joint aspiration). All cases of intrapelvic migration of an acetabular component do not systematically command a subperitoneal approach. The presence of some residual bone shell, an intrapelvic foreign body, or a path deviation from normal in a vascular bundle or an ureter must be analyzed before deciding on the approach. The potential problems managing this mode of loosening event are a reminder for the need of periodical total hip arthroplasty follow-up. This regular monitoring helps preventing complications sometimes life threatening.

In the case of revision with press-fit stems, the importance of secondary subsidence should not be overestimated, because it usually does not negatively affect satisfactory osseointegration.
