Overview

The Nondisplaced diaphyseal fractures of the shafts of ulna is rare, and its deformity is often obvious, with the patient supporting the deformed and injured limb with the other hand. Also, the orthopedic surgeon should consider a careful neurological evaluation of the motor and sensory functions of the radial, median, and ulnar nerves. The Ulnar Bone Fractures might be very painful, causing difficulties in moving the arm or elbow.

Ulnar Bone Fracture Physical Exam

The related signs and symptoms include:

• Edema of the forearm
  • Most of the time the edema will be a non-pitting edema
  • Depends on the edema extent, it may even lead to compartment syndrome in the anterior and internal compartment of forearm
• Bruising
  • As a manifestation of internal injury to the local vessels by trauma or fractures bone
• Decrease in range of motion
  • Movement of the fractures limb will be painful if possible at all
• Tenderness
• Deformity
  • Fractured bone deformity may be touchable in the internal side of the forearm if the fracture is displaced

In the physical exam the orthopedic surgeon should check the vascular status and amount of swelling in the forearm. In polytrauma patients or in comatose or obtunded patients a tense compartment with neurological signs or stretch pain should be considered as the compartment syndrome, and the compartment pressures should be measured and monitored.

Physical examination of patients with Ulnar bone fracture is usually remarkable for swelling, tenderness, bruises, ecchymosis, deformity and restricted range of motion of the wrist.

Appearance of the Patient Patients with Ulnar bone fracture usually appears normal unless the patients had a high energy trauma causing the open wound fracture. Vital Signs Weak pulse may be seen when associated with polytrauma. Low blood pressure with normal pulse pressure may be present due to compound fracture with blood loss. Skin Skin examination of patients with Ulnar bone fracture includes: Bruises Ecchymosis HEENT HEENT examination of patients with Ulnar bone fracture is usually normal. Neck Neck examination of patients with Ulnar bone fracture is normal. Lungs Pulmonary examination of patients with Ulnar bone fracture is usually normal. Heart Cardiovascular examination of patients with Ulnar bone fracture is usually normal. Abdomen Abdominal examination of patients with Ulnar bone fracture is usually normal. Back Back examination of patients with Ulnar bone fracture is usually normal. Genitourinary Genitourinary examination of patients with Ulnar bone fracture is usually normal. Neuromuscular Neuromuscular examination of patients with Ulnar bone fracture is usually normal. However, some patients may develop neuropraxia of the branch of the Ulnar nerve resulting in decreased sensation of thumb, index and middle finger. References
