Surgical management of complex post-tuberculous kyphosis among African patients: clinical and radiographic outcomes for a consecutive series treated at a single institution in West Africa

Disparities in the Clinical Profile of Spinal Tuberculosis in Africa: A Scoping Review of Management and Outcome

BACKGROUND

Spinal tuberculosis (STB) is a significant contributor to nontraumatic myelopathy. There is a rising burden in Africa, in parallel with the high prevalence of human immunodeficiency virus. We conducted a scoping review to highlight the disparities in the management and outcomes of STB in Africa.

METHODS

This study was conducted using the Preferred Reporting Items for Systematic Reviews and Meta-Analysis extension for scoping review guidelines. AJOL, Embase, MEDLINE, Google Scholar, and Cochrane CENTRAL databases were searched to identify all relevant peer-reviewed articles published on the management of STB in African centers, excluding abstract-only articles, literature reviews, and meta-analyses.

RESULTS

Sixty studies were eligible for inclusion, comprising data from 3416 patients aged 8 months to 89 years (median, 32 years). Thoracic and lumbar segments were the most commonly affected vertebral regions (thoracic = 42.7%; lumbar = 35.9%). The most common clinical features were back pain and neurological deficits. Lack of essential laboratory and imaging diagnostic infrastructure was a common problem. Patients received antitubercular therapy (ATT) for varying durations, and only 18.3% underwent surgery. A favorable outcome was achieved in 51.6% of patients, 20.3% developed a permanent disability, and the mortality rate was 2.1%. Treatment outcome was adversely affected by a high rate of late presentation and treatment default.

CONCLUSIONS

ATT remains the mainstay of treatment; however, the duration of treatment varied widely among studies. Further research is required to explore the feasibility and efficacy of short-course ATT in treating STB in the African population.

Posterior fixation, anterior debridement and bone grafting in the treatment of thoracic and lumbar tuberculosis in children younger than 3 years of age

PURPOSE

This study aimed to investigate the clinical outcomes of posterior fixation, combined with one- or two-stage anterior debridement and bone grafting in treating children younger than 3 years of age with thoracic and lumbar tuberculosis.

METHODS

This was a retrospective study involving 16 young children with thoracic or lumbar tuberculosis. Surgical data were recorded. Frankel Grade was used to assess neurological function. The regional kyphosis angle was measured to evaluate the deformity correction. Erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) levels were detected to assess the activity of tuberculosis. Bony fusion and complications were also recorded.

RESULTS

The mean operation time was 204.4 ± 41.8 min. The mean estimated blood loss was 126.3 ± 94.4 ml. Preoperative Frankel Grade results indicated five patients with Grade C, six with Grade D, and five with Grade E. At the final follow-up, all patients were in Grade E. Twelve patients were brought back to normal spinal alignment and the rest four patients remained kyphotic. There was an improvement of 29.3° ± 18.3° in regional kyphotic angle postoperatively. And the deformity correction was 27.4° ± 19.1° at the final follow-up. ESR and CRP decreased to a normal range at three months follow-up. Bony fusion was achieved in all patients. None of the cases developed fixation failure, pseudoarthrosis, or tuberculosis recurrence.

CONCLUSION

Posterior fixation, combined with one- or two-stage anterior debridement and bone grafting, is a safe and effective surgical strategy for treating young children with thoracic and lumbar tuberculosis.

Understanding the Ghanaian Neurosurgical Literature: A Scoping Review and Bibliometric Analysis

BACKGROUND

Research serves to bolster clinical neurosurgery by critically assessing various disease pathologies, while identifying important challenges and opportunities. However, there is limited information on the landscape of the Ghanaian neurosurgical literature.

METHODS

A scoping review and bibliometric analysis was conducted in accordance with PRISMA guidelines. PubMed, Embase, Global Index Medicus, and Web of Science electronic databases were searched from inception until December 21, 2021 for English language articles about neurosurgery in Ghana.

RESULTS

927 articles were identified and 66 were ultimately included in the analysis. A majority of them, 42.4%, were retrospective cohort studies, with 62.1% published after 2010. There were no randomized controlled or basic science studies. Most articles were published in the West African Journal of Medicine (24.2%) and non-infectious/non-traumatic spinal pathology was the most commonly discussed topic (22.7%); 66.7% of articles included only authors affiliated with Ghanaian institutions, and international collaborators frequently originated from the United States (15.9%). Only 22.7% of the manuscripts reported a funding source. Commonly reported challenges included limited sample sizes, delays in diagnosis and treatment, and lack of proper diagnostic tools and specialized care.

CONCLUSIONS

This review revealed that while the Ghanaian academic neurosurgery output has been increasing over time, these have been limited to cohort studies largely assessing spine pathology. The Ghanaian neurosurgical research environment may be bolstered by an increase in research funding, the establishment of longitudinal clinical databases, training in research methodology, increased incentives for researchers, strengthening of research collaborative networks, and increased engagement of neurosurgical trainees in research.
