Pediatric case of a penetrating lumbar spinal injury.

PURPOSE: Penetrating spinal injuries are generally extremely rare and are seldom encountered in pediatric patients. The non-compliance of pediatric patients with physical examination can sometimes delay diagnosis and treatment. Here, we present a case of a child who had a fall and suffered penetrating spinal trauma due to a small glass fragment. CASE REPORT: A penetrating foreign body was detected in the lumbar spinal region of a 2-year-old patient with complaints of increased restlessness on physical activity followed by difficulty in walking. The patient was operated on and followed up without any complications in the perioperative and late postoperative periods. CONCLUSION: A detailed physical examination is necessitated in the pediatric age group because of insufficient anamnesis. The high number of patients per physician, especially in societies having a low socioeconomic standard, prevents detailed examinations, and unnecessary examinations may cause delays in diagnosis. However, one must note that the skin findings of pediatric patients can be very helpful, especially in pediatric neurosurgery, and examination should not be neglected.

Management of non-missile penetrating spinal injury.

Review of the literature with case illustration. Non-missile penetrating spinal injury (NPSI) represents a small subset of spinal cord injuries at tertiary trauma centers and is comprised mostly of knife violence. Strict guidelines for the management of penetrating spinal cord injury remain elusive given the variability of mechanisms, rarity of clinical experience, and paucity of prospective studies. A review of the literature was conducted by search of the National Library of Medicine (PubMed) in the English language through June of 2018. Additional articles were culled from the reference lists of the included series. Eleven case series totaling 1007 patients, along with 21 case reports, were identified. In summary, magnetic resonance imaging (MRI) may be beneficial in assessing incomplete or progressive spinal injuries and can be considered with retained foreign bodies in select cases. Forty-eight hours of antibiotic prophylaxis is likely sufficient to prevent infection. Puncture wounds should be debrided, washed, and closed. Retained foreign bodies should be removed in the operating room and often require laminectomy. Early intervention is preferred. Non-missile penetrating spinal injury has a higher likelihood of neurologic recovery as compared to other traumatic spinal injuries.

Pedicled multifidus muscle flaps to treat dural tears due to penetrating spinal stab wounds: Two case reports and a literature review.

Background: Penetrating spinal injuries occasionally lead to dural tears (DT) and cerebrospinal fluid (CSF) leaks that risk both infectious and neurological complications. Here, we reviewed two cases and the literature regarding the safety/efficacy and limitations of repairing traumatic DT utilizing pedicled multifidus muscle flaps. Case Description: Two males, ages 73 and 50, presented with Brown-Sequard syndromes and DT/CSF fistulas attributed to knife-induced spinal injuries at the D3-D4 and D11-D12 levels. Intraoperatively, DT was repaired utilizing pedicle multifidus muscle flaps. Postoperatively, both patients demonstrated partial recovery of neurological function along with no residual symptoms/signs of DT/CSF fistulas. Conclusion: Penetrating traumatic spinal injuries may result in DT/CSF fistulas that can be adequately repaired utilizing pedicle multifidus muscle flaps.

The Inception of the "Two Trolley Technique" for Supine Positioning in a Patient With Penetrating Injury to the Back.

Penetrating trauma to the back causes the anesthesiologist many difficulties in airway management and obtaining central lines due to the inability to position supine. Lateral position intubation for the same has been described earlier but still remains unfamiliar. Here, we describe the case of a stab injury to the back and how we achieved the optimal supine position using the "Two Trolley Technique."

Bullet retrieval from the cauda equina after penetrating spinal injury: A case report and review of the literature.

BACKGROUND: When gunshot injuries occur to the spine, bullet fragments may be retained within the spinal canal. Indications for bullet removal include incomplete spinal cord injury, progressive loss of neurologic function including injury to the cauda equina, and dural leaks with impending risk of meningitis. CASE DESCRIPTION: Here, we present a 34-year-old male with a missile penetrating spinal injury to the cauda equina. In addition to the computed tomography scan demonstrating retention of a bullet in the left L1/2 disc space, the scan suggested likely dural injury. The patient underwent a decompression/instrumented fusion with retrieval of the retained bullet fragment. A laminectomy was performed from T12 to L3, and at L1 and L2, a large traumatic durotomy was identified and repaired. The patient, unfortunately, continued to have bilateral lower extremity plegia with neurogenic bladder/bowel dysfunction at 1-year follow-up. CONCLUSION: We discuss the operative management and provide an intraoperative video showing the bullet extraction and dural closure.

Nonmissile penetrating spinal injuries: Mechanisms, expectations, and management.

BACKGROUND: Nonmissile penetrating spinal injury (NMPSI) is an uncommon form of traumatic injury to the spine. Here, we present a comprehensive and contemporary literature review that provides insight into NMPSI-type injuries, their mechanisms, clinical practice, management, and expectations. METHODS: An extensive review of the published literature was conducted in PubMed, OVID Medline, and EMBASE journals for studies of nonmissile penetrating spine injuries. Terms for search included NMPSI and nonmissile penetrating spinal cord injury. No date restrictions were used. RESULTS: The search yielded only 17 related articles. Cross-checking of articles was conducted to exclude duplicate articles. The 17 articles were screened for their full text and English language availability. We finalized those articles pertaining to the topic. CONCLUSION: The mechanism of injury in NMPSI occurs in two different stages. Immediate injury is caused by direct damage to the neurological structures. The delayed injury response is caused by damage to the spinal vasculature and activated immune response pathways. Computed tomography (CT) angiograms or formal diagnostic angiograms are indicated to identify vascular injury or development of pseudoaneurysm and can be performed both preoperatively and postoperatively. Surgically, decompressive procedures include laminectomies and hemilaminectomies. Dural exploration may be indicated if a cerebrospinal fluid leak with fistula develops from dural puncture. Further research and technologies are being developed to provide patients who have suffered NMPSI with more resources for a better quality of life.

Regional and Institutional Practice Variations in Decompressive Spine Surgery for Patients with Penetrating Spinal Injury in the United States.

BACKGROUND: The surgical management of penetrating spinal injury (PSI) has been widely debated in the literature, and the benefit of decompressive surgery for neurological function remains controversial. No national guidelines exist for the PSI population, and surgical practice patterns are unknown. We studied regional and institutional trends in the surgical management of PSI in the United States from 1988 to 2011. METHODS: The National Inpatient Sample database was accessed to identify a 20% stratified sample of PSI admissions to US hospitals from 1988 to 2011. PSI patients were divided into surgical (SXPSI) and nonsurgical (NSXPSI) groups, and these groups were analyzed across several regional, institutional, and patient-related variables. RESULTS: A total of 6632 PSI admissions were identified between 1988 and 2011. Decreased age (P = 0.002) and male gender (P = 0.015) were significantly more common in SXPSI than NSXPSI. Surgical rates were higher in teaching hospitals (P < 0.001), large hospitals (P = 0.012), and non-Northeast region hospitals (P < 0.020). Surgical management was associated with decreased mortality, increased length of stay, and increased total hospital charges (P < 0.001). CONCLUSIONS: Decompressive surgery rates for PSI differ significantly across regions and institutions in the United States. Institutional bias, patient preferences, and regional practice patterns all influence decision-making in PSI. A lack of large outcome studies in PSI and the absence of national guidelines contribute to variation in practice patterns. Our study indicates the need for future studies to better describe outcomes in patients with PSI.

Backstabbing swordfish: a rare cause of traumatic hemiparesis.

Swordfish attacks on humans are uncommon, with only a few case reports available in the current literature. The authors report the first known case of a penetrating spinal injury from a swordfish, in which the patient presented with a small stab wound and hemiparesis. The presentation of a fisherman with hemiparesis and a harmless-looking stab wound must alert clinicians to the possibility of penetrating swordfish injuries to the spine.

Firearm bullet settling into the lumbar spinal canal without causing neurological deficit: A report of two cases.

BACKGROUND: Uncertainty still exists regarding the treatment of the patients presenting with gunshot wounds to the spine. Neurological insults, cerebrospinal fluid fistula, infection, lead or copper toxicity, migration of bullets, and spinal instability are included among the common challenging issues. CASE DESCRIPTION: An 18-year-old woman was admitted with low back pain following a gunshot injury five days ago. She was neurologically intact. Radiological examinations showed that a bullet was settled in L4-5 disc space. The bullet was removed with a unilateral L4-5 partial hemilaminectomy and discectomy from the left side. The second case was of a 29-year-old man admitted with radiating leg pain on the right side following a gunshot injury from his left side of lower back four months ago. He had only positive straight leg raising test. Radiological studies showed two bullets, one was in the psoas muscle on the left side and the other was in spinal canal that had caused a burst fracture of the L5 vertebra. Following L5 laminectomy and bilateral L5-S1 facetectomy, the bullet was removed from the spinal canal and L5-S1 transpedicular posterior stabilization was performed. The postoperative period of both patients was unremarkable. CONCLUSION: Bullet settling into the lumbar spinal canal without causing neurological deficit may require surgical intervention. Removal of bullets provided not only pain relief in both the cases but also prevented future complications such as migration of the bullets, plumbism, and neuropathic pain and instability.

Stab wound to the intramedullary spinal cord: Presurgical and surgical management options for a retained blade to optimize neurological preservation.

BACKGROUND: We present a rare case of an intraparenchymal nonmissile penetrating spinal injury (NMPSI) occurring at the T11 level in a patient presenting without neurological deficit. CASE DESCRIPTION: The patient sustained a knife wound that penetrated the lamina without incurring bony injury and entered the spinal cord at the T11 level. During surgery, the intramedullary penetration of the cord was confirmed, and following surgical removal of the knife, the patient fully recovered without losing any neurological function. CONCLUSIONS: The surgical management of NMPSI in patients who are neurologically intact is controversial. Here, we report surgical excision of a knife that penetrated the spinal cord at the T11 level, without the patient incurring further neurological deterioration.

Nonmissile penetrating spinal injury with an impaled knife: case report.

We report a case of non missile penetrating spinal injury (NMPSI) caused due to an impaled knife in the lumbar region. The patient was neurologically preserved and presented with the knife blade retained in his back. The wound with the knife in situ was explored, the knife removed and a dural laceration was repaired. The wound healed without evidence for cerebrospinal fluid leakage or infection.

Penetrating spinal injuries and their management.

Penetrating spinal trauma due to missile/gunshot injuries has been well reported in the literature and has remained the domain of military warfare more often. Civic society's recent upsurge in gunshot injuries has created a dilemma for the treating neurosurgeon in many ways as their management has always involved certain debatable and controversial issues. Both conservative and surgical management of penetrating spinal injuries (PSI) have been practiced widely. The chief neurosurgical concern in these types of firearm injuries is the degree of damage sustained during the bullet traversing through the neural tissue and the after-effects of the same in long term. We had an interesting case of a penetrating bullet injury to cervical spine at C2 vertebral level. He was operated and the bullets were removed from posterior midline approach. Usually, the management of such cases differs from region to region depending on the preference of the surgeon but still certain common principles are followed world over. Thus, we realized the need to review the literature regarding spinal injuries with special emphasis on PSI and to study the recent guidelines for their treatment in light of our case.
