Summary
Image-guided fixation offers a precise solution for complex humeral head fractures, achieving excellent outcomes. This minimally invasive technique ensures accurate screw placement, avoiding complications and restoring shoulder function.
Area of Science:
- Orthopaedic Surgery
- Traumatology
- Medical Imaging
Background:
- Treatment for three- and four-part humeral head fractures remains debated, with options including primary arthroplasty and primary fixation.
- Navigation technology is established in spine and joint replacement surgery but underutilized in trauma surgery due to technical challenges.
Observation:
- A case study details a minimally invasive approach for a three-part humeral head fracture using image-based guided headless compression screws.
- The navigation system (Surgix) facilitated precise screw placement on the first attempt, with a total radiation time of 60 seconds.
Findings:
- At 12-month follow-up, radiographs confirmed fracture consolidation, no screw loosening, and good glenohumeral articulation.
- The patient experienced full shoulder function, no pain, and excellent functional scores (Constant score 98, DASH score 0), with no evidence of humeral head necrosis.
Implications:
- Image-based guidance enables accurate fixation of humeral head fractures, supporting minimally invasive surgery.
- This technique demonstrates potential for improved outcomes in shoulder traumatology, warranting further exploration of navigation systems in this field.
