Forearm deformities in multiple cartilaginous exostoses

Area of Science:

• Orthopedics
• Hand Surgery
• Pediatric Orthopedics

Background:

• Forearm deformities present complex challenges in pediatric orthopedics.
• Accurate classification and measurement are crucial for understanding deformity progression.

Purpose of the Study:

• To classify forearm deformities.
• To correlate specific measurements with deformity severity.
• To investigate metacarpal length in patients with forearm deformities.

Main Methods:

• Review of 16 patients with 20 forearm deformities.
• Classification of deformities into three types.
• Measurement of ulnar tilt, carpal displacement, ulnar shortening, and metacarpal lengths.

Main Results:

• Deformity severity correlated with ulnar tilt, carpal displacement, and relative ulnar shortening.
• Significant metacarpal shortening was observed in most patients, with or without exostoses.
• Metacarpal shortening showed a correlation with deformity type and severity.

Conclusions:

• Forearm deformity severity can be objectively measured.
• Metacarpal shortening is a common finding in these deformities.
• Measurements provide valuable insights for surgical planning and prognosis.
