Treatment of Non-Displaced Intraarticular Proximal Fracture
Initial Treatment Approach
- The American College of Surgeons recommends treating non-displaced intraarticular proximal fractures with removable splinting for 3-4 weeks combined with immediate active finger motion exercises, with mandatory surgical fixation if displacement exceeds 3mm, dorsal tilt exceeds 10 degrees, or any loss of joint congruity develops 1, 2
- Removable splinting is the treatment of choice for truly non-displaced intraarticular fractures at proximal locations, such as the metacarpal base or phalangeal base, as recommended by the American Academy of Orthopaedic Surgeons 1, 3, 2
Critical Thresholds Requiring Surgical Intervention
- Surgical fixation becomes mandatory if displacement exceeds 3mm, dorsal tilt exceeds 10 degrees, or any loss of joint congruity develops, as stated by the Orthopaedic Trauma Association 1, 3, 2
- The American Academy of Orthopaedic Surgeons recommends surgical intervention for intra-articular step-off of any significance 1
Mandatory Follow-Up Protocol
- The American College of Radiology recommends obtaining radiographs at 3 weeks post-injury to detect delayed displacement that would require surgical conversion 1, 2
- Repeat imaging at the time of immobilization removal (3-4 weeks) is recommended by the American Academy of Orthopaedic Surgeons to confirm adequate healing 1, 3, 2
Special Consideration for Hip Fractures
- The American Academy of Orthopaedic Surgeons recommends that all undisplaced intracapsular hip fractures should undergo internal fixation with multiple screws or sliding hip screw, as conservative treatment carries a 30-50% risk of subsequent displacement 4, 5
- Conservative treatment of hip fractures is associated with increased morbidity, mortality, and reduced chance of returning home, according to the American Geriatrics Society 5
