Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
simple decompression
Simple decompression
Fracture fixation will be performed through a posterior approach, as this provides excellent visualization of the distal fragments. A triceps split will be used to expose the distal humerus. A midline incision will be made from proximally to distal onto the shaft of the ulna. Equal portions of the triceps muscle will be reflected medially and laterally, with use of sharp dissection to remove the triceps insertion from the olecranon. The ulnar nerve will be identified and protected proximal and distal to the medial epicondyle. Fracture fixation will be performed after anatomic reduction using standard fixation techniques and plate fixation on both the medial and lateral column.
In the simple ulnar nerve decompression group, no further treatment of the ulnar nerve will be undertaken.
anterior subcutaneous transposition
anterior subcutaneous transposition
In the anterior transposition of the ulnar nerve group, the ulnar nerve will be placed subcutaneously anterior to the medial epicondyle free from any pressure.

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
* Displaced, distal humerus fracture (OTA 13A or 13C) as seen in radiographs
* Fractures ≤ 28 days post injury
* Closed fractures
* No history of previous ulnar neuropathy or elbow pathology
* Provisin of informed consent
Exclusion Criteria
* History of previous ulnar neuropathy or elbow pathology
* Fractures more than 28 days post-injury
* Limited life expectancy due to significant medical co-morbidity or medical contraindication to surgery
* Inability to comply with rehabilitation or form completion
* Likely problems, in the judgement of the investigators, with maintaining follow-up (i.e. patients with no fixed address, patients not mentally competent to give consent, etc.)
