Correlation between Adult Height and Metacarpal Length Using Advanced Imaging Modalities

Area of Science:

• Orthopedic research
• Radiology
• Human anatomy

Background:

• Metacarpal length is a key anatomical measurement.
• Understanding the correlation between body height and metacarpal dimensions is crucial for clinical applications.

Purpose of the Study:

• To evaluate the correlation between adult height and metacarpal length using computed tomographic (CT) scans.
• To determine if significant differences exist among various finger metacarpals.

Main Methods:

• Analysis of 40 CT scans from skeletally mature adults.
• Measurement of metacarpal lengths using the Sectra IDS7 platform.
• Statistical analysis including Pearson correlation coefficients and independent sample t-tests.

Main Results:

• A statistically significant positive correlation (average r=0.71) was found between height and metacarpal length across all fingers.
• The index metacarpal showed the strongest correlation with patient height.
• Average metacarpal lengths were recorded for index, long, ring, and small fingers.

Conclusions:

• Height is a reliable predictor of metacarpal length.
• Findings support the use of height in predicting metacarpal dimensions for orthopedic implant selection and surgical planning.
• CT scans offer precise measurements for bony anatomy assessment.
