Management of Non-Displaced 3rd MCP Fracture at 2 Weeks
A removable splint is not recommended for a 33-year-old male with a non-displaced 3rd MCP fracture with full range of motion at 2 weeks post-injury, as the fracture has likely already begun to heal and additional immobilization would provide minimal benefit while potentially causing unnecessary stiffness. 1
Assessment of Fracture Status
- At 2 weeks post-injury with full range of motion and a non-displaced fracture, the patient is already demonstrating good clinical progress 1
- Minimally displaced fractures with full range of motion typically have a favorable prognosis without prolonged immobilization 1
- The presence of full range of motion suggests that the fracture is stable and healing appropriately 2
Evidence-Based Approach to Immobilization
- Removable splints are an appropriate option for minimally displaced fractures during the initial treatment period, but not necessarily at the 2-week mark with full function 1
- For metacarpal fractures, immobilization is typically discontinued by 5 weeks, with position of immobilization having little effect on motion, grip strength, or fracture alignment 2
- Early mobilization of stable metacarpal fractures has been shown to provide good outcomes without compromising fracture alignment 3
Rehabilitation Considerations
- Active finger motion exercises should be performed to prevent stiffness, which is one of the most functionally disabling adverse effects of hand fractures 4
- Finger motion does not adversely affect adequately stabilized fractures 4
- Unnecessary prolonged immobilization may lead to joint stiffness and delayed return to normal activities 3
Special Considerations
- If the patient experiences unremitting pain, a reevaluation would be warranted 4
- Radiographic follow-up is typically recommended at approximately 3 weeks and at the time of immobilization cessation 1
- For this patient who already has full range of motion at 2 weeks, continued radiographic monitoring without additional splinting would be appropriate 1
Potential Pitfalls
- Prolonged immobilization beyond what is necessary can lead to:
- Conversely, inadequate immobilization of an unstable fracture could lead to malunion, but this is less likely given the patient's current clinical status with full range of motion 5
Conclusion for Clinical Practice
- For this 33-year-old male with a non-displaced 3rd MCP fracture showing full range of motion at 2 weeks, continued splinting is not recommended 1
- Instead, focus should be on maintaining and improving range of motion through active exercises 4
- Regular radiographic follow-up should be continued to ensure proper healing 1
