S42.446
Nondisplaced fracture (avulsion) of medial epicondyle of unspecified humerus
Clinical Classification Guidelines
Medical Intelligence & Overview
A nondisplaced fracture of the medial epicondyle of the humerus is a type of bone injury commonly seen in individuals who experience a fall or direct trauma to the arm. The medial epicondyle is a bony bump on the inner side of the lower end of the upper arm bone (humerus). When this area experiences a fracture without the bone fragments moving out of place, it’s classified as a nondisplaced fracture, often resulting from avulsion injuries where tendons or ligaments pull off a small piece of bone. This description aligns with ICD-10 code S42.446.
Causes & Symptoms
Clinical Causes: Direct trauma or blow to the inner elbow Falls onto an outstretched arm Sports injuries, especially in activities involving throwing or impact Sudden pulling actions, such as during vigorous sports movements or overuse
Key Symptoms: Pain localized on the inner side of the elbow Swelling or tenderness around the medial epicondyle Limited range of motion in the elbow joint Possible bruising around the area Discomfort during arm movements, especially when gripping or lifting Absence of deformity or bone displacement
Diagnostic & Treatment
Diagnosis Path: Diagnosis typically involves a clinical examination where a healthcare professional assesses pain, swelling, and movement limitations. Imaging studies, primarily X-rays, are essential to confirm the fracture and determine whether it is displaced or nondisplaced. In some cases, additional imaging such as MRI or CT scans may be used to evaluate associated soft tissue injuries and confirm the extent of the fracture.
Treatment Protocols: Rest and immobilization using a splint or cast to keep the elbow stable Application of ice to reduce swelling and pain Over-the-counter or prescribed medications for pain relief Limiting activities that strain the elbow during healing Gradual physical therapy to restore strength and mobility once healing progresses Surgical intervention may be considered if there are complications or if the fracture becomes displaced
