The recovery time of finger crush injury without stitches needs to be assessed according to the patient’s condition, treatment plan, etc. The recovery time may range from 2 weeks to several weeks, and in serious cases, it may take several months. If the wound is small and the injured part has good blood circulation, even without stitches, the wound may recover faster, and may gradually heal in about 2 weeks; if the wound is large and the blood circulation of the compressed part is poor, without stitches, the wound will recover slower, and is prone to infections, which may take weeks or even longer. When a finger is cracked by a crush injury, it is generally recommended to perform debridement and suture treatment, which will help to restore the tissue structure and blood flow, and help the wound to heal. If the wound is left to grow on its own without suturing, most patients can heal, but the healing time is significantly longer and can take weeks to months. When a finger is crushed and cracked, it is recommended that the patient seek medical attention in a timely manner, and under the guidance of a doctor, standardize treatment according to the condition, so as to avoid delayed healing of the wound affecting the recovery of finger function.
