Purpose:
We investigated the effectiveness of non-image-guided hip injections.
Methods:
We retrospectively evaluated 369 intra-articular hip injections in 331 patients using anatomical landmarks. The percentage and duration of pain relief was documented. Hip injections were grouped in responders and nonresponders (50 % maximum pain relief as a cut off).
Results:
In 82% (n = 304) of hip injections, patients responded positively and experienced >50 % pain relief. Nonresponders had a significantly higher body mass index (p = 0.007).
Conclusions:
Hip injections using anatomical landmarks are an effective treatment option for patients with osteoarthritis of the hip.

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
