Extremity Trauma Epidemiology

• Extremity Trauma (ET) is a term that encompasses a broad spectrum of injury severity with no consensus definition

• Epidemiology of Extremity Trauma not well defined

• Estimated 30,000 cases of OEF/OIF combat-related ET

• 19,000 required hospitalization

• Epidemiology of Civilian ET and military (non-combat related ET is also unclear)

Lower Extremity Assessment Project (LEAP)

• Project funded by NIH/ 8 Level 1 Trauma Centers

• 569 patients with severe lower extremity injuries (24 month f-up)

• Functional Outcome measure: Sickness Impact Profile (SIP)

• 42% with residual “severe disability” as measured by SIP

• Re-hospitalization rate higher in with limb reconstruction

• No differences in functional outcomes between limb reconstruction and amputation

• Outcomes influenced by socioeconomic status

N Engl J Med 2002;347:1924–1931.

Lower Extremity Assessment Project (LEAP)

• 397/569 patients contacted by phone (Average 84 months post-injury)

• Most of the patients reported that physical and psychosocial functioning had deteriorated since their 24-month follow-up

• 50% of the patients indicated severe disability

• One third in both groups re-hospitalized between 2 and 7 years

• No difference in SIP scores across both treatment groups

• Evidence-Based Orthopedic Trauma Working Group Meta Analysis• No significant differences in functional outcome including

competitive employment at least up to 7 years

The Military Extremity Trauma Amputation/Limb Salvage (METALS) Study

• Retrospective cohort study of 324 OEF/OIF Servicemembers with lower-limb injuries requiring either amputation or limb salvage

• The Short Musculoskeletal Function Assessment (SMFA) questionnaire was used to measure overall function

• Amputation group had better scores in all SMFA domains

• Amputation group with lower likelihood of PTSD and a higher likelihood of being engaged in vigorous sports

• There were no significant differences between the groups with regard to the percentage of patients with depressive symptoms, pain interfering with daily activities, or work/school status

Dynamic Bracing Considerations

• Persistent functional mobility impairments following severe lower extremity trauma

• Persistent loss of motor function

• Pain with weight-bearing (mechanical) vs. neuropathic pain

• Desire and potential to return to higher level activities including running

• Dynamic Bracing trial should be considered in most cases

• Delayed Amputation should not be considered a failure

It’s not just about the amputation

Page 48: Advances in Combat Amputee Care The VA Systems-Based Approach to Longitudinal Care · 2018-05-10 · Advances in Combat Amputee Care The VA Systems-Based Approach to Longitudinal

Trauma Associated Injuries

• Combat-related amputations are associated with moderate to severe injury severity scores (Scores in the 9-15 range)

• Higher Injury Severity Scores associated with: upper extremity amputationsproximal or bilateral lower extremity amputations

• Commonly associated injuries include: TBI, extremity injuries, burns, vision and hearing loss

• Personal Protective Equipment partial mitigation of life ending chest and torso injuries

• Extremities at greatest risk for complex blast injuries

Osteopenia and Osteoporosis

• Decreased Bone Mineral Density (BMD) reported in amputated residual limbs compared to intact limbs

• Severity of loss significant (28% difference) and not limited to the residual limb (lumbar spine)

• Potential relationship to decreased weight-bearing and force transmission (worse with TF level amputation)

• Osteoporosis characterized by a decrease in the outer bone width

• Concern for increased fracture risk, esp. with aging

Other Musculoskeletal Considerations

Overuse Syndromes• Remaining extremities, proximal joints, and spine• More common following upper extremity amputation• More common in bilateral lower limb amputation• Joint and energy conservation techniques important

Weight gain / Obesity• Very common• Potential to occur early or late• Multiple limb amputees at greater risk• Education and counseling important

Multiple Limb Amputation Longitudinal Considerations

• Self-rated health status: Excellent or Very Good (61% OIF/OEF)

• Performance high-impact aerobic activities18% (OEF/OIF) versus 3% (Vietnam)

• Long-term consequences and needs not fully known– Higher rate of co-morbid injuries– Potential increased risk of secondary complications – Medical and metabolic consequences

• Increase or decrease in prosthetic needs over time?

• Greater need for DME, other mobility devices, and assistive technology
