Olecranon fracture

What is the Olecranon?

The olecranon is the bony tip of the elbow and part of the ulna (ulna). This is where the triceps tendon comes in, which is responsible for extending the elbow. The olecranon forms a significant portion of the articular surface to the humerus (upper arm bone) and is therefore an integral part of the elbow joint.

• Function: Lever for the triceps muscle to extend the elbow
• Anatomical proximity: Bursa olecrani, skin, ulnar nerve runs medially (inside) on the elbow
• Load: High forces during support, shock loads and sporting movements

If the olecranon breaks, not only the bone is affected, but often also the extensor function - especially in the case of displaced fractures.

Causes and mechanism of accident

• Falling directly onto the tip of your elbow (e.g. on asphalt or steps)
• Fall on hand with bent elbow; Tension of the triceps tendon tears the olecranon
• Direct blow/impact in sports or traffic accidents

Risk factors include osteoporosis, older age, pre-existing elbow problems and contact sports. In rare cases, stress fractures occur due to repeated overloading.

Typical symptoms

• Severe, stabbing pain in the elbow, especially a. at the top
• Swelling, bruising and tenderness
• Limited mobility, especially stretching
• Palpable sensation of steps or crepitation
• For open fractures: visible wound/bleeding
• Loss of strength when supporting or pushing

Diagnostics: Examination and imaging

At the beginning there is an anamnesis and physical examination: localization of the pain, range of motion, checking active extension and checking blood circulation, motor skills and sensitivity (especially on the ulnar side of the little finger).

• X-ray in two planes (especially lateral): standard for fracture assessment
• CT for complex, near-joint or multi-part fractures for surgical planning
• Ultrasound to assess effusion, bursa, tendon involvement
• MRI rarely necessary (soft tissue, unclear findings)

It is important to assess whether the fracture is displaced and whether the extensor function (triceps mechanism) is preserved. Concomitant injuries to the elbow (e.g. radial head or humeral condyle fractures, Monteggia injury) must be ruled out.

When should I go to the emergency room immediately?

• Open injury, severe misalignment or bone visibility
• Numbness, tingling or cold/pale hand
• Severe pain at rest despite painkillers
• High altitude/high energy accident or additional injuries

Ensure arm rest (e.g. triangular bandage), cool carefully and seek medical help immediately. We can be reached at short notice in Hamburg for an initial assessment.

Conservative treatment: when possible?

Not every olecranon fracture requires surgery. Conservative therapy is an option if the fracture is not displaced or is only minimally displaced and active extension against gravity is maintained.

• Immobilization in an upper arm-forearm splint (usually 60-90° flexion) for 1-2 weeks
• Elevation, cooling, adequate pain therapy
• Early guided range of motion exercises as soon as pain allows
• Regular x-ray checks to ensure stability
• Physiotherapy with a focus on pain-free mobility and swelling reduction

The healing time of the bone is usually 6-8 weeks. The aim is early functional follow-up treatment to avoid stiffness - without endangering the fracture site.

Surgical procedures – if appropriate

Surgery is considered for displaced fractures, loss of active extensor function, joint steps, open fractures, or combined injuries. The aim is to anatomically restore the joint surface and provide stable fixation for early movement.

• Tension band osteosynthesis (wire/Kirschner wires with cerclage): proven for simple, transverse fractures
• Screw tension strapping (cannulated screws with wire loop): alternative if the bone quality is good
• Plate osteosynthesis: for oblique, multi-fragmentary or osteoporotic fractures
• Intramedullary procedures/pins: selective
• Partial fragment resection with triceps advancement: Exception for severely fragmented fractures in older, low-stress patients

The surgical procedure is chosen individually depending on the fracture type, bone quality, activity level and accompanying injuries. Every surgery has benefits and risks; We discuss both transparently and evidence-based.

Follow-up treatment, splint and physiotherapy

Follow-up treatment is crucial for the functional result. It depends on the stability of the care and pain status.

• Thrombosis prophylaxis and duration of incapacity for work are determined individually
• Scar management and, if necessary, occupational therapy for everyday function
• Regular follow-up checks with functional and, if necessary, X-ray checks

Everyday life, work and sport

• Office work: often possible after 1-2 weeks (arm spared, splint if necessary)
• Manual work/overhead work: depending on the healing process, usually after 8-12 weeks
• Driving: only when safe, pain-free control of the vehicle is possible and cleared by a doctor
• Sports: ergometer/walking early, swimming/light strength training after 8-12 weeks, contact sports later

The return to everyday life takes place gradually. The aim is to achieve resilient, low-pain function – without overloading during the healing phase.

Possible risks and complications

• Elbow stiffness or restricted movement
• Implant irritation (especially with tension straps) with possible metal removal
• Delayed healing/non-union (pseudarthrosis)
• Persistence of pain, irritation of the bursa
• Wound healing disorders, infections
• Heterotopic ossifications (ossifications in soft tissue)
• Rare: nerve irritation, post-traumatic osteoarthritis

Stiffness and long-term symptoms can often be reduced through early functional but structured follow-up treatment. An individual risk explanation takes place before each therapy.

forecast

Most patients achieve good to very good function after adequate treatment. Bony healing usually takes 6-8 weeks, and complete return to function can take 3-6 months. The recovery time is longer for complex fractures or associated injuries.

Special features: children, athletes, osteoporosis

• Children/adolescents: often apophyseal tears; Protection of the growth plate, high remodeling capacity, individual therapy
• Athletes: high demands on stretching strength and mobility; phased return-to-sport program
• Osteoporosis: increased risk of fracture and possibly longer healing time; Think about osteoporosis diagnosis and therapy

Prevention and self-help

• Fall prevention: balance training, non-slip shoes, living space safety
• Sport: technical training, protectors for risky activities
• Bone strengthening: vitamin D, calcium and, if necessary, osteoporosis diagnosis
• Workplace: ergonomic adjustments, load distribution

After a fracture, a structured exercise program helps to regain mobility. We will show you exercises that are suitable for everyday use and provide clear stress limits.

Differentiation from other elbow problems

• Bruise/soft tissue injury without fracture
• Olecranon bursitis (bursitis)
• Triceps tendon rupture
• Other fractures: Radial head, humeral condyle or Monteggia injury
• Dislocation fracture of the elbow

Accurate imaging helps make the correct diagnosis and avoid over- or under-treatment.

What do guidelines and studies say?

Fracture displacement, joint involvement and extensor function are crucial. Conservative therapy for stable, non-displaced fractures is established. Surgical procedures aim at anatomical reconstruction and early functional mobilization. Implant irritation after tension strapping is not uncommon; The indication for metal removal is determined individually.
