Intra-articular hip injection using anatomic surface landmarks.

Area of Science:

• Orthopedics
• Musculoskeletal Imaging
• Pain Management

Background:

• Intra-articular hip injections are crucial for diagnosing and treating hip conditions.
• Current methods often rely on imaging guidance like ultrasound or fluoroscopy.
• There is a need for reliable, non-imaging techniques for hip injections.

Purpose of the Study:

• To describe a novel technique for intra-articular hip injection using surface anatomical landmarks.
• To provide a reproducible method for hip injections without the need for imaging guidance.
• To highlight the utility of this technique in outpatient settings and for pre-procedural injections.

Main Methods:

• A specific needle insertion point at the proximal anterolateral portal for hip arthroscopy was identified.
• A posterior needle trajectory of 30° was employed.
• The target was a precise anatomical junction defined by surface landmarks relative to the anterior superior iliac spine and greater trochanter.

Main Results:

• The described technique allows for accurate intra-articular hip injection using only surface anatomical landmarks.
• The method is suitable for use in an outpatient clinic setting without imaging.
• This approach minimizes the requirement for radiographic exposure, particularly for contrast injections prior to MRI arthrography.

Conclusions:

• A safe and effective landmark-based technique for intra-articular hip injection has been established.
• This method offers a valuable alternative to imaging-guided injections, especially in resource-limited settings or for routine procedures.
• The technique enhances patient safety by reducing radiation exposure and can be readily integrated into standard clinical practice.
