A distal ulna fracture refers to a break near the wrist end of the ulna, one of the two bones in the forearm (the other is the radius). This type of fracture is less common in isolation and often occurs along with a distal radius fracture, especially from falls on an outstretched hand (FOOSH).
Often seen with distal radius fractures.
May affect the triangular fibrocartilage complex (TFCC), impacting wrist stability.
May result from direct trauma or twisting injuries.
Less common.
Could be stable or unstable depending on displacement.
1. Pain and swelling on the ulnar side of the wrist.
2. Tenderness near the wrist, especially over the ulna.
3. Limited wrist or forearm rotation (supination/pronation).
4. Possible deformity if significantly displaced.
X-rays (AP, lateral, oblique views) – to assess displacement and associated injuries.
CT or MRI – if complex injury, intra-articular involvement, or TFCC damage is suspected.
Depends on fracture type, displacement, and involvement of adjacent structures.
Immobilization (e.g., short arm cast or splint) for 4–6 weeks.
Regular follow-up X-rays to monitor healing.
Closed reduction (manipulation) and casting, if possible.
Open Reduction and Internal Fixation (ORIF) – surgery to align and stabilize the bone with plates/screws if reduction fails or instability exists.
May require surgical intervention.
DRUJ = Distal Radioulnar Joint – critical for forearm rotation.
Begin gentle range of motion exercises after immobilization ends or as directed post-op.
Gradual return to normal activities.
Full recovery may take 8–12 weeks or more, depending on severity.
Malunion or nonunion.
Wrist instability (especially if TFCC or DRUJ is involved).
Chronic pain or stiffness.
Post-traumatic arthritis.
