Background: Penetrating spinal cord injury (pSCI) is uncommon in civilian settings. However, there is a lack of consensus regarding perioperative management and thresholds for operative intervention. This review explores the various trends in the management of pSCI along with a literature review.
Case Description: A 34-year-old male presented with a gunshot wound (GSW) to the left chest. Injuries included a pneumothorax, diaphragmatic injury, splenic injury, multiple small bowel injuries, transverse colon injury, and a bullet lodged at the L5 spinal level. The patient underwent chest tube placement, an exploratory laparotomy, splenectomy, diaphragmatic repair, multiple small bowel resections, and a transverse colon resection. Later on, the patient required a lumbar laminectomy for wound debridement and bullet excision.
Conclusion: The standards for the surgical management of pSCI are poorly defined. Older studies suggested that >7 days of antibiotics decreased the risk of infection associated with HVI while shorter regimens correlated with higher rates of spinal and neurologic infections (meningitis, paraspinal abscess, and osteomyelitis). Newer studies fail to confirm the benefit of extended antimicrobial therapy, noting no increased infections with 48 h or less of antibiotic use while suggesting increased risks of long-term antibiotic prophylaxis (i.e., antimicrobial resistance and Clostridium difficile infection). There is no current role for steroids in the treatment of pSCI, and routine operative management is no longer necessarily indicated.

The optimal management of penetrating spinal cord injury (pSCI) with accompanying HVI is poorly defined. Older studies recommended >7 days of antibiotics to decrease the risk of infection.[
Abdominal surgery and postoperative course
A 34-year-old male patient sustained a gunshot would (GSW) to the left chest. The chest X-ray showed a left pneumothorax warranting placement of a 36F chest tube. The chest/abdominal computed tomography (CT) scans showed free fluid in the abdomen warranting an exploratory laparotomy; it revealed a large-volume hemoperitoneum. The patient required a splenectomy, repair of a 2 cm diaphragmatic injury, two small bowel resections/repairs, and resection/repair of a transverse colonic injury. He was placed on broad-spectrum antibiotics (Zosyn) for 24 h during the perioperative period (both preoperative and postoperative doses administered).
Postoperative wound infection
However, postoperatively, he developed a wound infection at the laparotomy site (despite being left open for drainage), requiring staple removal, debridement, and drainage. He went on to develop an abscess in the left upper quadrant, requiring percutaneous drainage and peripherally inserted central catheter line placement for long-term antibiotics. Antibiotics were administered for several weeks.
Lumbar spinal pathology
The patient also originally presented with the following neurological deficits: weakness of both lower extremities (extensor hallucis longus: left>right) and bowel and bladder incontinence. Pelvic X-rays revealed a projectile lodged in the lumbar spine at the L5 level, and the abdominal/lumbar CT showed a projectile within the spinal canal at the L5 level.
Lumbar spine surgery: No postoperative lumbar wound complications
On the following day, the patient was taken to the operating room by the spine team where he underwent a decompressive laminectomy at the L4 and L5 level, with durotomy for excision of a small caliber bullet. The durotomy was appropriately repaired. Postoperatively, the patient exhibited partial neurologic recovery, characterized by incomplete return of motor function in both lower extremities (3/5 on dorsiflexion); eventually, he was able to ambulate with assistance.
Epidemiology and injury pattern
Penetrating spinal trauma contributes to 13%–17% of all spinal cord injuries (SCI). The cervical and thoracic spine are most commonly involved.[
X-ray and CT diagnostic studies
Plain films provide important initial information regarding the number, location, and trajectory of different projectiles.[
Multiple studies document infectious complications in pSCI, including osteomyelitis, meningitis, and paraspinal abscesses, particularly in the setting of injuries to the stomach and colon.[
Historically, steroids have been used in patients following pSCI. However, a retrospective analysis conducted by Levy et al. concluded that there was no benefit regarding functional outcomes or length of hospital stay.[
In the military setting, debridement with laminectomy and foreign body removal has been the preference of many surgeons.[
Outcomes and complications
A wide range of complications have been noted following pSCI including partial or complete neurologic deficits (e.g., 70% of cervical spine injuries result in complete deficit while 70% of lumbosacral injuries result in incomplete deficit, fistula formation, bowel and/or bladder incontinence, and chronic pain syndromes).[
A consensus regarding medical and operative management of penetrating spinal cord injury remains elusive. While extended antimicrobials have been used in the past their use can no longer be supported by the current literature. In addition, steroids have no role in the treatment of pSCI. Routine operative intervention has shown no benefits though specific indications exist.
