Distal Radius Fractures
What Is a Distal Radius Fracture?
A distal radius fracture — a break at the end of the larger forearm bone near the wrist — is one of the most common fractures in the body, typically caused by a fall onto an outstretched hand. It affects people of all ages, from children to older adults with weaker bone, and treatment ranges from simple casting to surgical fixation depending on how the bone is broken.
Why This Fracture Is So Common
The distal radius makes up a large part of the wrist joint, and a fall onto an outstretched hand transmits significant force directly into this area — making it one of the most frequently fractured bones. In children, these fractures often involve the growth plate and generally heal quickly. In older adults, especially those with osteoporosis, even a relatively low-energy fall can cause a fracture, since weaker bone breaks more easily.
Recognizing the Symptoms
Immediate pain, swelling, and often visible deformity at the wrist
Difficulty or inability to move the wrist or grip anything
Bruising that develops over the following day or two
In some cases, numbness or tingling in the fingers if nearby nerves are affected by swelling or displacement
Diagnosis:
X-rays confirm the fracture and show key details that guide treatment — how the bone fragments are angled, whether the fracture extends into the wrist joint itself, and how much the bone is shortened or displaced. These details matter because a fracture that looks similar on the surface can require very different treatment depending on this alignment.
Treatment Options
Nonsurgical:
For fractures that are minimally displaced or that can be realigned (reduced) and held in a good position, a cast or splint alone is often sufficient, with follow-up X-rays to confirm the bone stays properly aligned as it heals.
Surgical:
For fractures that are significantly displaced, unstable, involve the wrist joint surface, or that shift out of position even after an attempted reduction, surgical fixation — most commonly with a plate and screws — restores and maintains proper alignment. This is often recommended for active patients or when the fracture pattern makes it unlikely a cast alone will hold the bone in a good position.
Recovery
Nonsurgical fractures typically stay in a cast for around 4-6 weeks, followed by a period of regaining wrist motion and strength. Surgically treated fractures often allow for earlier, gentler wrist motion since the hardware holds the bone stable, though full strength and motion recovery still generally takes several months either way.
Frequently Asked Questions:
How do you know if a distal radius fracture needs surgery?
The decision is based on how displaced or unstable the fracture is, whether it involves the joint surface, and whether an attempted realignment holds — significantly displaced or unstable fractures generally do better with surgical fixation.
Can a distal radius fracture heal without a cast?
Stable, properly aligned fractures are usually still immobilized in a cast or splint even without surgery, since some support is needed while the bone heals; a small number of very stable fractures may be managed with less rigid immobilization, but this is decided case by case.
Will I regain full wrist motion after a distal radius fracture?
Most patients regain good functional motion, though this can take several months, and a structured hand therapy program often helps speed and maximize that recovery, especially after more significant fractures.
