Simple Decompression Versus Anterior Transposition of the Ulnar Nerve

A Multicentre, Randomized Trial of Simple Decompression Versus Anterior Transposition of the Ulnar Nerve for Acute, Displaced Fractures of the Distal Humerus Treated With Plate Fixation

Both simple decompression and anterior transposition of the elbow nerve (ulnar nerve) for acute displaced fractures of the elbow (distal humerus) treated with plate fixation are currently used by surgeons. We want to examine which treatment will overall give better results in regards to arm function and residual pain.

Inclusion Criteria:

• Men or women aged 16 to 60 years of age
• 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:

• Vascular injury
• 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.)
