Tendon injury may occur if the tip of the finger breaks off at the base of the distal phalanx near the palm of the hand, but generally does not cause tendon injury if the break is from the distal phalanx rudiment to the end of the fingernail.
The terminal tendon of the hand tendon is located at the base of the distal phalanx and may cause tendon injury if it breaks off between the base of the distal phalanx and the second phalanx. This is where the deep flexor tendon and the lateral tendon are located, which can be restored by reconstruction of the tendon stops.
If the disruption occurs from the distal phalanx to the end of the nail, the disruption usually does not damage the tendon because there is virtually no tendon attachment here.
In the case of tip breakage, it is recommended to consult a doctor for further examination, and to choose a reasonable treatment plan with the help of the doctor, and to carry out targeted treatment.
