Summary
Ballistic trauma to the lower extremities frequently causes nerve injuries, with many patients experiencing full neurologic recovery. Vascular injury increases the risk of nerve damage in these cases.
Area of Science:
- Orthopedic Trauma Surgery
- Neurology
- Vascular Surgery
Background:
- Ballistic trauma to the lower extremities presents a significant challenge in trauma care.
- Nerve injuries are a common complication, impacting patient outcomes.
- Understanding the frequency and recovery patterns of these injuries is crucial.
Approach:
- Retrospective cohort study of patients over 16 years old with lower extremity ballistic trauma.
- Analysis of institutional trauma database from a level 1 trauma academic medical center.
- Inclusion of all identified patients presenting between May 2018 and May 2019.
Key Points:
- 14% of lower extremity ballistic trauma cases involved nerve injuries.
- 73% of patients with nerve injuries achieved complete recovery.
- Vascular injury was present in 38% of patients with nerve injuries, compared to 3% without.
Conclusions:
- Lower extremity nerve injuries are common in ballistic trauma.
- Vascular injury is a significant risk factor for neurologic deficits.
- High index of suspicion for vascular injury is recommended in patients with ballistic lower extremity nerve palsy.

The external iliac artery transitions out of the body cavity, entering the femoral region of the lower leg, and is renamed the femoral artery at the point where it traverses the body wall. This artery is responsible for the distribution of blood to the thigh's deep muscles and the skin's ventral and lateral regions, achieved through several minor branches and the lateral deep femoral artery, which also spawns a lateral circumflex artery. The knee area receives blood from the genicular...

01:21Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation
51
Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...
