Aetiology
Superficial injuries of the finger or thumb can be caused by a variety of mechanisms, including blunt trauma, sharp objects, lacerations, and burns.
Diagnosis
A physical examination of the finger or thumb is necessary to identify the extent of injury and to rule out any deeper tissue damage. X-rays may be necessary to determine the extent of any bone damage.
Differential diagnosis
Other conditions that may cause similar symptoms include fractures, dislocations, tendinitis, and nerve injuries.
Treatment
Treatment of superficial injuries of the finger or thumb will depend on the severity of the injury. Minor injuries may be treated with rest, ice, elevation, and over-the-counter pain medications. More severe injuries may require wound care, splinting, and a referral to a specialist.
Prognosis
With proper treatment, most superficial injuries of the finger or thumb will heal with minimal complications. However, if left untreated, the injury may result in chronic pain, stiffness, and decreased range of motion.
