Open Fracture

Overview

An open fracture — sometimes called a compound fracture — is a broken bone that communicates with the outside environment through a wound in the skin and soft tissues. These injuries almost always result from high-energy trauma such as motor vehicle collisions, falls from height, motorcycle accidents, and crush injuries. A degloving injury, in which the skin and underlying tissue are stripped away from the bone, can accompany or complicate an open fracture.

Open fractures are treated as orthopedic emergencies. The combination of a broken bone and contaminated soft tissue dramatically increases the risk of infection, which is one of the most serious complications in orthopedic trauma. Our San Diego fellowship-trained trauma surgeons are experienced in the full spectrum of open fracture management, from initial wound care through definitive fixation and reconstruction.

How Open Fractures Are Graded

The Gustilo-Anderson classification is the standard system for describing open fractures and guiding treatment:

• Grade I — A clean wound smaller than 1 cm, with minimal soft tissue damage
• Grade II — A wound larger than 1 cm without extensive soft tissue damage or avulsion
• Grade IIIA — Extensive soft tissue damage with adequate bone coverage
• Grade IIIB — Extensive soft tissue damage with exposed bone requiring soft tissue reconstruction
• Grade IIIC — Any open fracture with an associated arterial injury requiring repair

Higher-grade injuries carry greater risk of infection and often require a coordinated plan involving orthopedic trauma, plastic surgery, and vascular surgery.

Initial Management

When a patient with an open fracture arrives in the emergency department, the priorities are life-threatening injury assessment, hemorrhage control, and early antibiotic administration. IV antibiotics should be started as soon as possible — ideally within the first hour. The limb is splinted, the wound is covered with a sterile dressing, and the patient is moved to the operating room for urgent surgical debridement.

Surgical Treatment

The cornerstone of open fracture care is thorough surgical debridement — the removal of contaminated or devitalized tissue. The wound is irrigated with large volumes of saline, and all dirt, foreign material, and nonviable tissue is excised. Depending on the injury, the surgeon then stabilizes the fracture using one of several techniques:

• External fixation is often used for heavily contaminated injuries or when the patient is too unstable for definitive surgery. Pins are placed above and below the fracture and connected to an external frame that holds the bone in alignment while the soft tissues recover.
• Intramedullary nailing can be used for select open long-bone fractures once the wound is clean and stable.
• Plate and screw fixation (ORIF) may be appropriate for periarticular fractures or when definitive stability is needed from the outset.

In higher-grade injuries, multiple debridements may be necessary before the wound is ready for definitive closure. Soft tissue coverage may require skin grafting, rotational muscle flaps, or free tissue transfer in coordination with a plastic surgeon.

Recovery

Recovery from an open fracture takes longer than recovery from a comparable closed injury, and the exact timeline depends on the grade of the injury, the bone involved, and the patient’s overall health. Weight bearing is typically restricted for several weeks to months. Close follow-up is essential to monitor for infection, ensure the bone is healing, and transition into physical therapy when it is safe to begin.

Despite the severity of these injuries, most patients recover meaningful function with appropriate treatment.
