[Short-stem THA-complications and therapy options].

Abstract

Short stems in total hip arthroplasty are increasingly being established and offer several advantages in terms of minimal invasiveness and bone preservation compared to standard implants. The rounded design and shorter stem length facilitate better adaptation to natural anatomy, at the same time also posing specific risks and complications. When transitioning to short stems, a learning curve must be considered. Careful patient selection and preoperative planning are crucial, and intraoperative imaging is recommended. The most common implant-specific complications include insufficient osseointegration, leading to subsidence and aseptic loosening, as well as periprosthetic fractures. The risk instability and dislocations as well as periprosthetic infections can potentially be reduced with short stems. This article discusses the frequency, causes, and treatment options for these types of complications and highlights current evidence-based treatment approaches.
