Broken Thumb – Overview
A broken thumb refers to a fracture in one or both of the bones that make up the thumb — the distal and proximal phalanges, or in some cases, the first metacarpal near the wrist. This is a significant injury due to the thumb’s essential role in grip, balance, and fine motor skills. Even a minor fracture can severely impact daily activities like writing, dressing, or holding objects.
Thumb fractures often result from a fall, direct impact, or sporting injury. Common scenarios include bracing during a fall, jamming the thumb during ball sports, or injuring the hand in a car or workplace accident. While some thumb fractures are clean breaks, others may involve joint surfaces or be part of more complex hand injuries.
Symptoms appear quickly after the injury. These include pain, swelling, bruising, and difficulty moving or using the thumb. A visibly deformed thumb or one that cannot be straightened is a strong indicator of a serious break. If left untreated, this can heal incorrectly, leading to loss of function, arthritis, or chronic pain.

Diagnosis typically involves a physical exam and X-rays. For complex fractures or suspected ligament damage, a CT or MRI scan may be necessary. Treatment ranges from splinting and immobilisation to surgical fixation using wires, pins, or plates — especially if the fracture is unstable or involves a joint.
Healing time for a broken thumb ranges from four to eight weeks. Physiotherapy is often required after immobilisation to restore strength, mobility, and precision. Prompt treatment significantly improves outcomes and reduces the risk of long-term impairment.
