Methods: Thirty-four formalin-fixed upper extremities were dissected. A projection of the LCL onto the radial head was marked with a needle. The percentage of the posterior border of the radial head overlaid by the LCL was digitally measured. A portion of the projection of the LCL was statistically correlated with the overall diameter of the radial head. Results: The overall diameter of the radial head was 21.2mm±2.3. The proportionate projection of the medial border of the LCL onto the radial head was 5.3±1.6mm on average. The lateral 25% of the radial head was overlaid by the LCL with a maximum value of 40% on average. The inter- and intraobserver reliability showed very good accordance with the digital measurements (r>0.8). Conclusion: Care must be taken when performing a resection in the lateral 40% of the radial head, whereas resection in the medial 60% of the radial head appears to be safe. The LCL is an important stabiliser of the elbow joint, a lesion of which by undeliberate arthroscopic dissection may lead to joint instability. Iatrogenic injury to the LCL presumably can be prevented when respecting the given data. Level of evidence: Experimental study.
