Intra-articular hip injections are commonly performed for both diagnostic and therapeutic interventions. Because of the risk of damage to neurovascular structures, fluoroscopic guidance with injection of contrast material has been established as the gold standard to ensure proper needle placement into the intra-articular space. However, fluoroscopically guided intra-articular hip injections put patients at risk due to radiation exposure. ⋯ This study demonstrates that increasing BMI leads to elevated radiation dose during fluoroscopically guided intra-articular hip injections. The increased radiation experienced by patients with a larger BMI, however, is likely negligible.
