# Osteonecrosis of the Hip Misdiagnosed as Lumbar-Disc Herniation: Тhree Case Studies

## TL;DR

This paper discusses three cases where hip osteonecrosis was initially misdiagnosed as lumbar disc herniation, highlighting the importance of proper imaging for accurate diagnosis.

## Contribution

The study emphasizes the use of MRI scans of the hip joint alongside lumbar spine imaging to avoid misdiagnosis in patients with overlapping symptoms.

## Key findings

- Hip osteonecrosis can present with symptoms similar to lumbar disc herniation, leading to misdiagnosis.
- MRI scans are more effective than X-rays in detecting hip joint pathologies like avascular necrosis.
- Comprehensive imaging and evaluation are crucial for accurate diagnosis and improved patient outcomes.

## Abstract

Disc herniation and hip-joint pathology may present with overlapping symptoms, complicating the diagnosis and treatment strategy in some cases. To ensure a correct diagnosis, this study emphasizes the need for imaging methods like MRI scans of the hip joints, complementary to the lumbar spine, when in doubt of coexisting hip pathology with symptomatic lumbar disc herniation. A typical complaint in clinical practice among patients with lumbar disc herniation is chronic back pain, often radiating down the legs. Although there could be considerable overlap in pain between hip joint issues and disc herniation, the etiology of these two conditions might differ. In these situations, a comprehensive diagnostic evaluation is crucial, as demonstrated by the three clinical case studies provided here. This article underscores the importance of conducting thorough imaging tests such as hip-joint and spine MRI scans to accurately differentiate among various disorders. Pathologies such as avascular necrosis can go unnoticed on X-rays of the hip joint, but an MRI scan provides a more precise diagnosis in these situations. The cases described here highlight the challenge of differentiating between hip-joint pathology and disc herniation due to their similar symptoms. For a diagnosis to be made quickly and accurately, modern imaging techniques must be used in conjunction with a comprehensive diagnostic approach and physical examination, which will improve patient outcomes and enable proper management.
