Study Notes
Humeral Shaft Fractures
- The most common mechanism of injury is a direct blow or a fall onto an outstretched hand.
- Typical clinical presentations include pain, swelling, and deformity in the arm, with possible numbness or tingling in the hand or fingers.
- Careful neurovascular (NV) examination is important to assess for nerve or blood vessel damage.
Classification of Distal Humerus Fractures
- No specific classification mentioned.
Treatment Principles for Humeral Shaft Fractures
- Treatment principles focus on restoring alignment, stabilizing the fracture, and allowing for early mobility.
- Recommended timing for treating closed humeral shaft fractures is within 1-2 weeks.
- Open humeral shaft fractures require urgent treatment, typically with surgical debridement and antibiotic administration.
Fracture Patterns and Types
- Fracture patterns are based on the stress applied, including transverse, oblique, and spiral fractures.
- The most common type of humeral shaft fracture is a transverse fracture.
- Approximately 80-90% of humeral shaft fractures heal with nonsurgical management.
Olecranon Process Fractures
- Common symptom is pain at the posterior elbow, especially with flexion.
- First step in treatment for a nondisplaced olecranon process fracture is immobilization in a long arm cast.
- Possible symptom of a coronoid process fracture is instability of the elbow.
Elbow Stability and Fractures
- The coronoid process is believed to be the secondary stabilizing source for the elbow during valgus stress.
- The most common elbow fracture among adults is a distal humerus fracture.
Imaging and Treatment
- Olecranon process fractures can usually be demonstrated by X-ray or CT scan.
- Displaced olecranon process fractures may require open reduction and internal fixation (ORIF) for proper alignment of the bone.
- Avulsion fracture of the coronoid process can be caused by a violent traction force on the brachialis muscle.
- Loss of motion can occur regardless of treatment after healing from an olecranon process fracture.
- Patients with radial head fractures may experience elbow pain and stiffness, with possible instability.
