Abstract:
We describe three patients who developed meralgia paraesthetica after the use of a well-padded and carefully-placed patient-positioning device in total hip replacement.
Insights
Meralgia paresthetica, a nerve condition causing thigh numbness, can occur after total hip replacement surgery. Careful patient positioning is crucial to prevent this complication during the procedure.
Area of Science:
- Orthopedic Surgery
- Neurology
- Patient Safety
Background:
- Total hip replacement (THR) is a common orthopedic procedure.
- Patient positioning devices are used to optimize surgical access and outcomes.
- Nerve-related complications, though rare, can occur during orthopedic surgery.
Observation:
- Three patients developed meralgia paresthetica postoperatively.
- The condition followed the use of a specific patient-positioning device during THR.
- The device was described as well-padded and carefully placed.
Findings:
- A potential association exists between the use of this positioning device and the development of meralgia paresthetica.
- The mechanism may involve direct or indirect compression of the lateral femoral cutaneous nerve.
- Symptoms included sensory disturbances in the thigh region.
Implications:
- Highlights the importance of vigilant monitoring for nerve injuries during THR.
- Suggests a need to evaluate the biomechanical effects of patient-positioning devices.
- Emphasizes meticulous surgical technique and device management to mitigate risks.

Complications during healing arise when tissue repair is altered by local or systemic factors. These changes involve abnormal collagen deposition, altered biomechanics, and reduced vascular supply, impairing restoration of normal structure and function.Loss of FunctionScar tissue differs significantly from the original tissue it replaces. In the skin, fibrosis lacks adnexal structures such as hair follicles, sebaceous glands, and sweat glands. Their absence reduces tactile sensitivity, impairs...
