Study Notes

Treatment Options for Fractures

Open reduction and internal fixation with small screws is the standard for displaced fractures.
Comminuted fractures may require radial head excision or artificial head replacement.
Closed reduction and cast immobilization is often used for slipped lower radial epiphysis for 3-4 weeks.

Complications of Lower End Radius Fractures

Circulatory impairment may occur post-fracture.
Hypoesthesia can present over the ulnar one-and-a-half fingers.
Weakness in ulnar-innervated muscles is a possible symptom.

Fractures of the Distal Humerus in Adults

Three types exist:
- Extra articular supracondylar fractures.
- Intraarticular unicondylar fractures.
- Bicondylar fractures.
Undisplaced fractures may be treated with a posterior slab with the elbow flexed at 90 degrees and gentle movements after one week.

Best Treatment for Distal Humerus Fractures

Displaced fractures typically require open reduction and internal fixation.

Common Complications in Distal Humerus Fractures

Possible vascular injury.
Nerve injury leading to weakness.
Stiffness in the joint.
Heterotopic ossification may occur.

Forearm Fractures

Monteggia fracture involves ulna shaft fracture with disruption of the proximal radioulnar joint and dislocation of the radiocapitellar joint.

Characteristics of Radial Head Fractures

Commonly seen in young adults and children.
Colles fracture is notable for dorsal displacement above the wrist.

Scaphoid Fractures

Symptoms include localized tenderness in the anatomical snuff box, limited wrist movement, and swelling on the radial side.
Diagnosing may require X-ray, CT scan, MRI, or bone scan.

Management of Scaphoid Fractures

Stable non-displaced fractures are treated non-operatively with a thumb spica cast for 2-3 months.
Pulsed electromagnetic fields assist in treating delayed union.

Surgical Management for Scaphoid Fractures

Open reduction and internal fixation is required for unstable or displaced fractures and nonunion cases.
Percutaneous screw fixation is another surgical option.

Complications of Scaphoid Fractures

Nonunion of the scaphoid may necessitate surgical intervention using bone grafts.

Pediatric Fractures and Emergencies

Displaced supracondylar fractures in children are emergencies due to potential brachial artery risk.
Signs of ischemia must be monitored.

Treatment of Pediatric Fractures

Open reduction and internal fixation with K-wires is advised for displaced lateral condyle fractures to prevent nonunion and cubitus valgus.
Malunion is a common complication in supracondylar fractures, leading to stiffness.

Elbow Dislocation

Typically results from falls on an outstretched hand, often with posterior dislocation of forearm bones.
Hypoesthesia and weakness can be symptoms associated with nerve injury.

General Notes on Fracture Management

Continuous assessment for vascular and nerve injury is critical after any fracture.
Immobilization techniques must be applied to prevent further injury and alleviate pain.
