Management of Colles' Fracture
Initial Assessment and Reduction
For displaced Colles' fractures, closed reduction with cast immobilization is the primary treatment approach, though both manual manipulation and finger-trap traction achieve similar reduction quality with high rates of subsequent displacement during cast treatment. 1
Reduction Technique Options
- Manual manipulation and finger-trap traction produce equivalent initial reduction success rates (87% satisfactory alignment) and similar failure rates, with no significant difference in fracture position at any time point 1
- The "handshake technique" represents a simple, reliable manual reduction method that can be employed 2
- Critical caveat: Regardless of reduction method, substantial redisplacement occurs during cast immobilization—only 50-57% maintain acceptable alignment at 1 week, and only 27-32% at 5 weeks 1
Immobilization Position
Immobilize the forearm in supination rather than pronation to minimize loss of reduction. 3
- The brachioradialis muscle is the primary deforming force causing loss of reduction when the forearm is pronated, as it attaches to the distal radius and displaces the fracture fragment 3
- For unstable fractures (Type II and IV): Supination positioning achieves 85% excellent/good results compared to only 40-67% in pronation 3
- Initial immobilization should be in an above-elbow cast holding the forearm in relaxed supination with the wrist in slight flexion and ulnar deviation for approximately 11 days 3
- After 11 days, transition to a forearm brace that permits elbow flexion but prevents pronation and limits terminal elbow extension 3
Operative vs Non-Operative Decision-Making
Most Colles' fractures can be successfully treated with closed reduction and cast immobilization. 4
- Non-displaced or minimally displaced fractures: Simple immobilization is appropriate 5
- Surgical intervention should be reserved for fractures unlikely to achieve satisfactory functional and cosmetic results with non-operative treatment 3
- The specific indications for surgery remain controversial, as complication rates have not clearly demonstrated superiority of surgical over non-surgical approaches 3
Postoperative/Post-Reduction Management
Appropriate pain management is essential throughout treatment. 6
- Close monitoring with follow-up imaging is necessary to ensure proper healing and detect loss of reduction 5
- Early mobilization and rehabilitation should begin once fracture stability allows 6
Rehabilitation Protocol
Implement a comprehensive rehabilitation program including early physical training, muscle strengthening, and long-term balance training. 6
- Begin rehabilitation early after fracture stability is achieved 6
- Continue balance training long-term for fall prevention 6
Secondary Fracture Prevention
All patients over 50 with a Colles' fracture require systematic evaluation for osteoporosis and subsequent fracture risk. 6
- Ensure adequate calcium and vitamin D intake 6
- Counsel patients to stop smoking and limit alcohol intake 6
- Consider pharmacological treatment with agents proven to reduce vertebral, non-vertebral, and hip fracture risk 6
- Educate patients about disease burden, risk factors, and treatment duration 6
Common Pitfalls
- Underestimating redisplacement risk: Even with successful initial reduction, the majority of fractures lose acceptable alignment during cast treatment 1
- Immobilizing in pronation: This position allows the brachioradialis to displace the fracture, particularly in unstable patterns 3
- Failing to address osteoporosis: Missing the opportunity for secondary prevention in fragility fractures leads to subsequent fractures 6
