When is nail surgery recommended for a bruised nail?

A subungual haematoma is blood trapped beneath the nail after an injury. A small, comfortable bruise can be observed while the nail grows out. Severe throbbing pressure, a large collection of blood, a split nail, or a wound around the nail may call for a closer assessment. The clinician also checks whether the fingertip or toe is broken and whether the nail bed has been cut. Nail surgery can involve draining trapped blood, repairing the nail bed, or temporarily lifting or removing the nail to reach an injury. The appropriate choice depends on the timing, examination, and appearance of the nail.

Arrange medical assessment after a forceful crush, trapped finger, or painful darkening that is not easing. Until then, protect the digit, keep it raised, and use a wrapped cold pack for short periods. Do not drill, burn, or puncture the nail at home. Keep any cut clean and covered, and follow advice about pain relief if you can take it. Bring details of when the injury happened and whether the nail lifted, split, or lost feeling. A clinician may examine circulation, sensation, movement, the nail plate, and nearby skin before discussing Nail Surgery.

Seek prompt care if the digit is bent, numb, unusually pale or cold, or difficult to move. An open wound, increasing swelling, spreading redness, pus, fever, or worsening pain also needs assessment. These findings can indicate a deeper injury or infection and are not reasons to wait for the bruise to grow out. If the nail changes colour without a clear injury, arrange a dermatology review rather than assuming it is a haematoma.

Ask whether the nail bed or bone may be injured, whether drainage would help the pressure, and how the nail will be protected afterward. You can also ask what signs of infection to watch for, how long regrowth may take, and whether the nail plate should remain in place.
