Abstract:
We report a case of macrodactyly in which a finger was shortened and the nail bed and root implanted proximally using a vascularized pedicle. Electron microscopic findings showed that there was focal and segmental degeneration of myelin sheath and neurofilaments of axon.
Insights
This study details a macrodactyly case where a finger was surgically shortened and the nail bed reimplanted. Electron microscopy revealed nerve damage, specifically myelin sheath and axon degeneration.
Area of Science:
- Hand surgery
- Microsurgery
- Neuropathology
Background:
- Macrodactyly is a rare congenital condition characterized by disproportionate overgrowth of digits.
- Surgical correction often involves complex procedures to restore function and aesthetics.
- Understanding the underlying nerve pathology is crucial for surgical planning and outcomes.
Observation:
- A case of macrodactyly involving digital shortening and proximal nail bed/root implantation via a vascularized pedicle was managed.
- Surgical intervention aimed to address the digital overgrowth and associated nail deformities.
- The procedure utilized microsurgical techniques for precise tissue transfer.
Findings:
- Electron microscopy demonstrated focal and segmental degeneration of the myelin sheath.
- Axonal neurofilaments also showed signs of degeneration in affected nerve tissues.
- These neuropathological findings provide insights into the potential nerve involvement in macrodactyly.
Implications:
- The findings highlight the importance of considering neuropathological changes in macrodactyly management.
- Microsurgical techniques can be applied to complex digital reconstructions.
- Further research may elucidate the relationship between macrodactyly and nerve degeneration.
