Simple Decompression Versus Anterior Transposition of the Ulnar Nerve

Brief Summary:
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.

Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: 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
Study Start Date : September 2010
Actual Primary Completion Date : September 2018
Actual Study Completion Date : September 2018

Arm Intervention/treatment
Active Comparator: simple decompression Procedure: 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.

Active Comparator: anterior subcutaneous transposition Procedure: 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.

Primary Outcome Measures :
  1. The primary outcome will be signs of ulnar neuropathy, measured using two clinical staging systems to assess the degree of dysfunction of the ulnar nerve (the classification system of Gabel and Amadio13). [ Time Frame: 1 Year ]

Secondary Outcome Measures :
  1. Secondary outcome measurement will include a patient-oriented, limb-specific, functional measurement questionnaire (Disabilities of the Arm, Shoulder and Hand Instrument-DASH) [ Time Frame: 1 Year ]
