A hairline fracture refers to a crack in the bone that does not involve significant displacement, making it relatively less severe compared to other fractures. However, hairline fractures still require active treatment.

For treating a hairline fracture, it is possible to use plaster casts or braces for protection and stabilization. Typically, protection is needed for about four to six weeks to effectively aid recovery. During the recovery period of a hairline fracture, it is important to focus on a nutritious diet, incorporating foods rich in high-quality protein, calcium, and vitamins. Additionally, anti-inflammatory painkillers and traditional Chinese medicines that promote blood circulation and remove blood stasis can be used to facilitate the healing of the fracture. After the removal of the stabilizing device, it is crucial to promptly engage in functional rehabilitation exercises to improve joint function and promote recovery.
