Objective:

To analyze patients with split hamate fractures as a distinct entity and assess their clinical and radiological outcomes, emphasizing the unique challenges they present.

Key Findings:
  • Split hamate fractures are rare and often associated with CMC dislocations, highlighting their clinical significance.
  • Surgical intervention is necessary for all cases to restore carpal stability.
  • Follow-up assessments showed varying degrees of recovery and functional limitations, indicating the need for tailored rehabilitation.
Interpretation:

The study highlights the complexity of split hamate fractures and the importance of tailored surgical approaches to optimize functional recovery, suggesting that individualized treatment plans may enhance outcomes.

Limitations:
  • Small sample size with only 12 patients participating in follow-up, which may limit the generalizability of the findings.
  • Retrospective design may introduce selection bias.
  • Lack of long-term outcome data.
Conclusion:

Split hamate fractures require careful surgical management and follow-up to ensure optimal recovery, but further studies are needed to establish comprehensive treatment protocols and improve patient outcomes.
