The fracture of the 4th metacarpal is mainly caused by an external force on the patient’s hand and the exact recovery time after the fracture depends on the patient’s age, the extent of the fracture and the treatment method. If the fracture of the 4th metacarpal occurs in children, it can be treated conservatively and the patient can gradually recover within 3-4 weeks after treatment. If the 4th metacarpal fracture occurs in the elderly, the fracture takes longer to heal due to osteoporosis in the elderly and is also treated conservatively with a recovery time of approximately 6-8 weeks.
