Overview
what it is and why it mattersA distal humerus fracture is a break at the very bottom end of your upper arm bone — right at the elbow joint. Two patient groups: younger patients with healthy bone after high-energy trauma (a fall from height, a sports collision), and older patients with osteoporosis whose fragile bone breaks from a relatively minor fall. These fractures are technically demanding because the joint surface has to be put back together precisely, AND the elbow stiffens easily — so the surgical fixation has to be stable enough to start moving the joint within days, not weeks.
Symptoms
what you may noticeAfter a fall onto a bent elbow or a direct blow, you'll have severe pain and rapid swelling around the elbow. The joint may look deformed — wider or angled abnormally — and you won't be able to bend or straighten the arm. Even gentle movement sends sharp pain through the entire elbow.
Numbness or tingling in your ring finger and small finger can develop quickly because the ulnar nerve runs along a bony groove right behind the fracture site and is vulnerable to swelling or displaced fragments. Bruising spreads from the elbow down the forearm and up the back of the arm over the first few days. In severe injuries, the skin over the elbow may tent or blister — a sign of significant fragment displacement that typically requires urgent fixation.
Diagnosis
exam first, imaging secondSevere elbow pain and swelling, and you can't use the arm. Standard front and side X-rays of the elbow start the workup. A CT scan with 3D reconstruction is essential for any case heading to surgery — it gives the surgeon a complete picture of every fragment before the operation.
Treatment Path
how care progresses at OSI1
Non-operative management
For minimally shifted fractures, in patients who weren't walking before the injury, or in patients whose other medical conditions make surgery too risky — a bag of bones approach that accepts some imperfect healing in exchange for getting motion back early.
Surgical Options at OSI
if non-operative care isn't enoughMost distal humerus fractures that have shifted need surgical fixation — both to restore the joint surface and to let you start moving the elbow within days, which is the single biggest factor in not ending up with a permanently stiff elbow.
