Summary
Computer-assisted hip replacement (CAHR) does not present a specific nerve injury risk. Transient nerve damage may occur in the first year post-surgery, but permanent disability is not evident.
Area of Science:
- Orthopedic Surgery
- Neurology
- Medical Technology
Context:
- Computer-assisted hip replacement (CAHR), utilizing systems like ROBODOC, is increasingly used in Germany.
- Growing patient and physician concerns exist regarding persistent pain and walking difficulties post-CAHR.
- The potential for nerve injury following CAHR requires investigation due to inconsistent neurological data.
Purpose:
- To determine the specific risk of nerve injuries associated with computer-assisted hip replacement (CAHR).
- To evaluate neurological and neurophysiological outcomes in patients who underwent CAHR.
Summary:
- A case series of 29 patients (30 operated joints) after CAHR with ROBODOC underwent systematic neurological and neurophysiological examination.
- Functionally relevant nerve injuries were identified in 3.1% of operated sites, leading to temporary disability within the first year.
- No permanent disability due to nerve injury was observed.
Impact:
- Findings suggest CAHR does not carry a specific risk of nerve injury.
- The incidence of transient nerve damage in the first year post-CAHR may be slightly higher than with conventional hip replacement.
- This study provides crucial neurophysiological data to address patient and physician concerns about nerve injury after CAHR.
