Overview
The distal humerus forms the upper half of the elbow joint and has a complex shape with two articular surfaces — the capitellum and the trochlea. Fractures here are often intra-articular and associated with significant comminution.
Non-operative treatment of displaced distal humerus fractures leads to stiffness and loss of function. Surgery restores the joint surface and provides enough stability to begin early motion, which is the single most important factor for a good elbow outcome.
Why it's done
Distal humerus ORIF is typically considered when imaging and the clinical picture together indicate that the fracture will not reliably heal or function without surgical stabilization. Common indications include:
Displaced intra-articular fracture
Articular step-off will lead to arthritis and loss of motion.
Supracondylar fracture with displacement
The bone column needs rigid fixation to allow early motion.
Open fracture or neurovascular compromise
Urgent surgery protects the soft tissues and nerves.
Fractures in the elderly with osteoporotic bone
Total elbow replacement may be considered for low-demand patients.
How it works
The elbow is typically approached from the back through an olecranon osteotomy or a triceps-sparing exposure. The joint surface of the distal humerus is reconstructed first with small screws, and then two perpendicular or parallel plates are applied along the medial and lateral columns.
The ulnar nerve is identified and protected throughout. Fluoroscopy and direct inspection confirm that the articular reduction is anatomic. The olecranon osteotomy, if used, is repaired with a tension-band construct or plate.
Recovery
Early elbow motion is critical. A removable splint is used for comfort, and supervised active and assisted motion begins early. Strengthening is added as pain allows. Full functional recovery takes time, with the arc varying from patient to patient. Ulnar nerve symptoms and elbow stiffness are the most common complications. Hardware is removed only for persistent symptoms.

Weight-Bearing After Repair
Controlled load is part of how bone heals. Once the fracture is stabilized with hardware, gentle weight through the limb stimulates the biology that builds callus and remodels bone — completely offloading a fixed fracture for too long can actually slow healing and stiffen the joint above and below. Full body weight right away, however, can overload the construct before bone has caught up. The right answer sits in between: a partial weight-bearing progression decided by your surgeon based on your fracture pattern, the strength of the fixation, your bone quality, and how the repair looks on post-op imaging. We tell you exactly how much weight the limb can take, when to advance, and what to watch for.
Risks & Why We Still Recommend It
Every operation carries risk. The reason we offer this procedure is that the condition, left untreated, causes a destroyed elbow joint surface that becomes permanently stiff and painful. That is the trade we are managing — not eliminating risk, but choosing the smaller of two unfavorable trajectories.
The risks we discuss with patients before distal humerus orif include:
- bleeding and infection
- anesthesia risk
- stiffness (this is the dominant long-term issue after any distal humerus fracture)
- ulnar nerve irritation
- hardware irritation
- non-union, particularly through the olecranon osteotomy if one was used
- heterotopic ossification
- post-traumatic arthritis
The indication to proceed is a displaced intra-articular distal humerus fracture. Patients who don't need this operation don't get it.
