Objective: Spinal trauma (STx), with or without spinal cord injury (SCI), represents a significant global health burden, particularly in low- and middle-income countries (LMICs). International guidelines often assume the availability of resources for intensive care and surgical management, limiting their applicability in resource-constrained settings. A resource-adapted approach may improve management in these contexts.

Objective: In resource-limited settings, the standard of care prescribed in developed countries for either operative or nonoperative management of traumatic intracranial hematomas (TICHs) frequently has to be adapted to the economic and infrastructural realities. This study aims to present the outcome of selected cases of TICHs managed nonoperatively without routine intensive care unit admission, repeated cranial computed tomography (CT) scan or intracranial pressure monitoring at a rural neurosurgical service in a developing country.

Methods: This was a retrospective analysis of a cohort of our patients with cranial CT-confirmed TICHs selected for nonoperative treatment from our prospective head injury (HI) register over a 42-month period.

Background: Awake craniotomy (AC) is a common neurosurgical procedure for the resection of lesions in eloquent brain areas, which has the advantage of avoiding general anesthesia to reduce associated complications and costs. A significant resource limitation in low- and middle-income countries constrains the usage of AC.

Objective: To review the published literature on AC in African countries, identify challenges, and propose pragmatic solutions by practicing neurosurgeons in Africa.

Background: Traumatic brain injury (TBI) is increasingly recognised as being responsible for a substantial proportion of the global burden of disease. Neurosurgical interventions are an important aspect of care for patients with TBI, but there is little epidemiological data available on this patient population. We aimed to characterise differences in casemix, management, and mortality of patients receiving emergency neurosurgery for TBI across different levels of human development.

Introduction: Traumatic brain injury (TBI) accounts for a significant amount of death and disability worldwide and the majority of this burden affects individuals in low-and-middle income countries. Despite this, considerable geographical differences have been reported in the care of TBI patients. On this background, we aim to provide a comprehensive international picture of the epidemiological characteristics, management and outcomes of patients undergoing emergency surgery for traumatic brain injury (TBI) worldwide.

Cranioplasty (CP) after decompressive craniectomy (DC) for trauma is a neurosurgical procedure that aims to restore esthesis, improve cerebrospinal fluid (CSF) dynamics, and provide cerebral protection. In turn, this can facilitate neurological rehabilitation and potentially enhance neurological recovery. However, CP can be associated with significant morbidity.

Attempts at reconstruction of posttraumatic craniofacial defects (PTCDs) can be a challenge in low-resource practice areas of the world where the needed biomaterials are logistically beyond reach. A simple low-profile technique of autologous osteosynthesis for PTCD using the titanium clamps is presented in this report. In addition, a 6-year prospective database on a consecutive cohort of patients who underwent this procedure was analyzed for clinical, functional, and aesthetic outcomes, both in-hospital and at midterm follow-up.

Background: The extant literature on the surgical treatment of posttraumatic compound, complex frontal basal calvarial skull fracture suggests that this be a staged procedure. There are many socioeconomic constraints in low-resource regions of the world to the feasibility of this standard practice.

Methods: A single-stage operative procedure for the surgical treatment of these fractures in a neurosurgery practice in Nigeria is here annotated.

Article Synopsis
  • There is a lack of scientific reports from sub-Saharan Africa regarding spontaneous intracerebral hemorrhage (sICH), but a 5-year hospital database was used to study this condition.
  • The study involved 63 patients, predominantly male, with a median age of 55.7 years; most cases were linked to uncontrolled hypertension and presented with severe symptoms after a median delay of 72 hours.
  • sICH primarily affected areas of the brain like the ganglion and thalamus, with a substantial number showing signs of intraventricular hemorrhage, highlighting the critical nature of the condition and the need for timely intervention.

Many studies have been undertaken in Nigeria on maxillofacial trauma. However, only a few have considered both the skeletal and soft tissue injuries (in general) involving all the aspects of the maxillofacial region or considered other etiological sources of trauma apart from road traffic crashes. Fewer still have reviewed the outcome of management of facial injuries in our low-resource environment.

Introduction: The traditional care of patients with subacute/chronic subdural haematoma (S/CSDH) often involves delayed mobilization after burr-hole drainage. It is thought that delayed mobilization aids brain re-expansion thereby reducing the risk of recurrence. However, there is paucity of information regarding its efficacy and safety over early mobilization.
