Distal Radius Fractures: Should You Get Surgery?

A broken wrist is one of the most common fractures in adults. The treatment decision is not always obvious. Some distal radius fractures heal beautifully in a cast. Others fall apart in the cast within a week and require surgical fixation. The decision rests on specific patterns of bone alignment, joint surface involvement, and the patient's hand demands. This article walks through how a hand surgeon thinks about cast versus surgery for a distal radius fracture and what each pathway looks like.

The Anatomy of the Distal Radius

The radius is the larger of the two forearm bones, on the thumb side. The distal radius forms most of the wrist joint surface and articulates with the scaphoid and lunate carpal bones. A typical distal radius fracture occurs about 2 to 3 cm proximal to the wrist joint. The bone breaks because the radius is the main load-bearing bone of the forearm: when you fall on an outstretched hand, the energy transmits through the radius first.

Several alignment parameters matter for outcomes. Radial inclination (the radius tilts about 22 degrees toward the ulna). Volar tilt (the joint surface angles about 11 degrees forward). Radial length (the radius extends 11 mm beyond the ulna at the wrist). Articular congruency (the joint surface should be smooth, with step-offs less than 1 mm). When a fracture displaces these parameters significantly, the wrist mechanics change, and long-term function suffers if not corrected.

Cast Treatment: Who Is a Candidate

Closed reduction with cast immobilization works well for fractures that are:

• Nondisplaced or minimally displaced at presentation
• Reducible to acceptable alignment under local anesthesia
• Stable in the reduced position when followed at 1 to 2 weeks
• Extra-articular (the joint surface is not fragmented)
• In low-demand patients who prioritize avoiding surgery over restoring perfect anatomy

Cast treatment lasts 4 to 6 weeks. Hand therapy typically follows for 4 to 8 weeks. Most patients regain functional motion and adequate strength. The trade-off is that the cast restricts wrist motion completely during healing, which produces stiffness that takes weeks to recover.

Surgical Fixation: When It Is the Better Path

Open reduction with internal fixation (ORIF) using a volar locking plate is the workhorse for unstable distal radius fractures. The plate sits on the front of the radius, hidden behind the flexor tendons, and holds the bone fragments in correct alignment with locking screws while healing occurs. The advantages are stable fixation that allows protected wrist motion within 1 to 2 weeks, faster return to function, and more reliable anatomic restoration.

Specific indications that push toward surgical fixation include:

• Intra-articular extension with joint surface step-off greater than 1 mm
• Dorsal angulation greater than 10 to 15 degrees that does not reduce or reduces and slips back
• Comminution (multiple bone fragments) that resists cast control
• Radial shortening greater than 3 to 5 mm
• Loss of acceptable position in a cast at the 1 to 2 week follow-up
• Bilateral fractures where the patient cannot manage daily life with both hands casted
• High-demand patient (manual laborer, athlete, musician) who needs faster recovery
• Open fracture or fracture with associated nerve, vessel, or tendon injury

The Volar Locking Plate

The volar locking plate has revolutionized distal radius fracture treatment over the past 25 years. Before locking technology, surgical fixation was less stable, particularly in osteoporotic bone, and wrists often had to be casted after surgery just like non-surgical cases. Locking screws change that: they thread directly into the plate, creating a fixed-angle construct that holds osteoporotic bone reliably and allows protected wrist motion within 1 to 2 weeks of surgery.

The procedure takes 60 to 90 minutes under regional or general anesthesia at an ambulatory surgery center. Same-day discharge. Most patients are out of a splint within 1 to 2 weeks and into hand therapy. Sutures come out at 10 to 14 days. Bone healing takes 6 to 8 weeks. Functional recovery continues for 3 to 6 months.

Cast vs Surgery: Recovery Comparison

The two pathways differ most in the early phase of recovery:

• Cast treatment: 4 to 6 weeks of cast immobilization, then 4 to 8 weeks of stiffness recovery. Total time to functional use: 8 to 12 weeks.
• Volar plate ORIF: 1 to 2 weeks in a removable splint, then progressive motion. Total time to functional use: 4 to 8 weeks.

Long-term outcomes (6 months and beyond) are comparable for similar fracture patterns when both pathways are appropriately selected. The question is not "which is better" in absolute terms; it is "which is better for this specific fracture and this specific patient." A simple nondisplaced fracture in a 70-year-old retiree is well treated in a cast. A comminuted intra-articular fracture in a 35-year-old carpenter usually needs ORIF.

Why Early Evaluation Matters

The decision tree narrows quickly after the injury. A fracture that could be treated in a cast at presentation may shift in the first 7 to 14 days and become a surgical case. A fracture that has already started healing in poor alignment is much harder to fix at 4 weeks than at 4 days. Prompt evaluation, ideally within 1 to 3 days of the injury, gives the most options.

Most distal radius fractures are seen the same day or next day at our office. X-rays are obtained at the visit. The reduction is performed in the office or operating suite if needed. The surgical decision is made the same week. For patients who arrive at an emergency department first, we accept transfers and follow-up appointments quickly.
