What is a Pediatric Lateral Condyle Fracture?
A pediatric lateral condyle fracture is a type of elbow fracture in children that occurs at the outer (lateral) part of the distal humerus (lower end of the upper arm bone), where the bone forms the elbow joint. The lateral condyle is an important growth area and part of the joint surface, so fractures here require careful treatment.
What Causes a Pediatric Lateral Condyle Fracture?
A pediatric lateral condyle fracture is usually caused by trauma to the elbow. The most common cause is a fall onto an outstretched hand, which places stress on the outer elbow. It may also occur from direct impact during sports, playground accidents, or falls from height. Sudden twisting forces around the elbow can also lead to this fracture in children.
What are the Signs and Symptoms of a Pediatric Lateral Condyle Fracture?
Signs and symptoms of a pediatric lateral condyle fracture include pain and swelling on the outer side of the elbow, tenderness, and difficulty moving the joint. A child may avoid using the affected arm or hold it still due to pain. Bruising, stiffness, and limited elbow movement are common. In some cases, a visible deformity or instability around the elbow may appear.
How is a Pediatric Lateral Condyle Fracture Diagnosed?
Diagnosis of a pediatric lateral condyle fracture begins with a physical examination to check for pain, swelling, tenderness, and limited elbow movement. Doctors review the child’s injury history and symptoms. X-rays of the elbow are the main test used to confirm the fracture and assess displacement. In unclear cases, additional imaging such as CT scans or MRI may be recommended.
How is a Pediatric Lateral Condyle Fracture Treated?
Treatment of a pediatric lateral condyle fracture depends on how severe the fracture is and whether the bone has shifted.
Non-surgical treatment:
If the fracture is stable and not displaced, the child’s arm is placed in a long arm cast or splint to keep the elbow still while the bone heals. Regular X-rays are taken to ensure the fracture remains properly aligned.
Surgical treatment:
If the fracture is displaced or unstable, surgery may be required to realign the bone. Surgeons usually perform closed or open reduction with pin fixation, where small metal pins hold the bone in position during healing.
Early treatment is important to prevent growth problems, joint stiffness, or deformity.
Recovery:
Recovery after surgery involves immobilizing the arm in a cast or splint to protect the repaired bone. Follow-up visits and X-rays monitor healing. Once the fracture heals, gentle elbow exercises help restore strength and mobility, allowing the child to gradually return to normal activities.
