Which nerve needs to be identified during UCL reconstruction?

During UCL (Ulnar Collateral Ligament) reconstruction, the identification and protection of the ulnar nerve is crucial. This nerve runs in close proximity to the surgical field in the elbow region and is particularly at risk during the procedure. Care must be taken to avoid injury to the ulnar nerve, as damage can lead to significant functional deficits, including loss of sensation in the ring and little fingers or weakness in grip strength.

Avoiding injury to the ulnar nerve is a standard consideration in procedures around the elbow. Its anatomical relationship with the UCL makes its identification imperative for surgical success and patient recovery. Surgeons often utilize techniques to expose the ulnar nerve or strategically move it out of the way during the reconstruction to ensure it is not inadvertently damaged.

While there are other nerves in the vicinity, such as the lateral antebrachial cutaneous nerve, the medial antebrachial cutaneous nerve, and the radial nerve, they do not play as prominent a role in UCL reconstruction as the ulnar nerve does. Identifying and maintaining the integrity of the ulnar nerve ensures that patients do not experience adverse neurological outcomes following the operation.
