Overview

Spinal Cord Injury
Spinal cord injury is damage to the spinal cord that can interfere with movement, sensation, or normal control of body functions below the level of the injury. The severity depends on the location and extent of damage and whether the injury is complete or incomplete. Traumatic injuries may cause weakness, paralysis, altered sensation, pain, or problems with bladder and bowel function. Nontraumatic injuries can produce similar effects when disease or another medical condition damages or compresses the spinal cord.
Avascular Necrosis
Avascular necrosis, also called osteonecrosis, occurs when reduced blood supply causes bone tissue to die. It most often affects the hip but can involve other joints such as the knee, shoulder, or ankle. Early disease may cause no symptoms, while progressive damage can produce persistent pain, stiffness, reduced movement, and eventually collapse of the affected bone or joint surface. The condition may develop gradually and can be associated with injury, certain medicines, medical conditions, or other factors that impair blood flow to bone.

Diagnosis

Spinal Cord Injury
Diagnosis requires an urgent assessment of neurological function, including strength, sensation, reflexes, and other signs of spinal cord involvement. Imaging is used to identify damage to the spine and spinal cord. CT scans can show fractures or other structural injuries, while MRI can provide detailed information about the spinal cord, discs, ligaments, compression, bleeding, or soft-tissue damage. The neurological examination and imaging findings help determine the level and severity of injury.
Avascular Necrosis
Diagnosis is based on symptoms, physical examination, medical history, and imaging of the affected bone. X-rays may appear normal in early disease, while magnetic resonance imaging can detect changes at an earlier stage. Additional imaging may help determine the extent of bone damage or joint collapse. Blood tests and other investigations may be used to identify an underlying condition or contributing cause, particularly when disease occurs at an unusual age or without an obvious risk factor.

Prevention

Spinal Cord Injury
Many traumatic spinal cord injuries can be reduced by preventing serious accidents. Use seat belts and appropriate child restraints in vehicles, follow workplace safety procedures, and use suitable protective equipment during sports and recreational activities. Avoid diving into unfamiliar or shallow water. Reduce fall hazards at home, particularly for people at increased risk of falls. Never drive under the influence of alcohol or drugs, and follow established safety practices when using vehicles, machinery, or equipment.
Avascular Necrosis
Some cases of avascular necrosis cannot be prevented, particularly when an underlying medical condition is responsible. Risk may be reduced by avoiding excessive alcohol consumption, using corticosteroids only as medically indicated, and discussing long-term corticosteroid exposure with a healthcare professional. Prompt assessment after significant joint or bone injury may be appropriate. People with medical disorders associated with osteonecrosis may benefit from appropriate management and monitoring for complications.

Risk Factors

Spinal Cord Injury
Risk is increased by activities or circumstances associated with severe trauma, including high-speed vehicle crashes, falls from heights, contact or high-impact sports, violence, and unsafe diving or water activities. Older adults may have increased risk of spinal injury from falls, particularly when bone or balance problems are present. Failure to use seat belts, protective equipment, or appropriate workplace and recreational safety measures can also increase the likelihood of traumatic injury.
Avascular Necrosis
Risk factors include prolonged or high-dose corticosteroid use, heavy alcohol consumption, previous fractures or joint trauma, and certain medical conditions affecting blood vessels or blood clotting. Associations have also been reported with disorders such as sickle cell disease, lupus, certain metabolic disorders, and some organ-transplant or cancer-related conditions. The risk varies according to the underlying cause, duration of exposure, and the location and extent of impaired blood supply.
