Key Findings:
  • The patient had stable morphology of the fourth metacarpals over more than a decade.
  • She maintained a full, pain-free range of motion in both hands after conservative management.
  • No history of hand dysfunction was reported, even with high-level athletic participation.
Interpretation:

This case suggests that bilateral congenital shortening of the fourth metacarpal can be compatible with high-level athletic participation without functional limitations.

Limitations:
  • Formal grip dynamometry and validated functional scores were not utilized.
  • The study is based on a single case report, limiting generalizability.
Conclusion:

Conservative management with reassurance is appropriate for asymptomatic patients, and recognition of this condition can prevent misinterpretation as trauma-related shortening.
