Overview
Fractures of the carpal bones, particularly the scaphoid and triquetrum, are critical due to their potential for vascular compromise and significant impact on hand function 1. These injuries require meticulous diagnosis and management to prevent long-term morbidity 12.Diagnosis
History and Examination: Focused history and detailed physical examination are crucial to avoid missing subtle injuries 1.
Radiography: Routine wrist radiographs may not suffice; special views like tomography are often necessary 15.
Imaging Techniques: MRI is valuable, especially in pediatric cases for diagnosing rare carpal fractures like capitate and hamate 4.
Bone Scans: Useful as a screening tool for detecting occult fractures 5.Management
Initial Management: Expedited evaluation and imaging to rule out associated injuries 2.
Treatment Based on Fracture Type:
- Intra-articular Fractures: Aim to restore joint congruity 5.
- Extra-articular Fractures: Small fractures may be treated with excision (e.g., pisiform) 5.
Collaborative Care: Involvement of sports medicine providers and other subspecialties for comprehensive management 2.
Return to Play: Tailored rehabilitation plans with multidisciplinary input to ensure safe return to activities 2.Special Populations
Pediatrics: MRI is particularly valuable for diagnosing carpal fractures in children due to subtlety and rarity 4.
Comorbidities: Consideration of chronic conditions that may complicate healing and functional recovery 2.Key Recommendations
Perform a thorough history and physical examination to avoid missing carpal fractures, especially those of the scaphoid and triquetrum (Evidence: Strong 1).
Utilize advanced imaging techniques such as MRI and tomography when routine radiographs are inconclusive, particularly in pediatric cases (Evidence: Moderate 45).
Collaborate with orthopedic and sports medicine specialists to ensure comprehensive care and safe return to activities post-fracture (Evidence: Expert opinion 2).References
