Study evaluated metacarpal shaft fractures treated with a stylet of 18–20-gauge spinal needles as an intramedullary elastic nail and K wire by measuring hand functions after fracture union. Range of motion, clinical, and radiological fracture union were assessed at 6 weeks and monthly until 6 months. Michigan's Score evaluates results. Clinical union time for patients treated with a stylet of spinal needle is faster and statistically significant than for those treated with K wire, whereas radiological union time is nearly the same and not significant.
