The Efficacy of Blended Learning in a Pediatric Spine Deformity Management Program in Sub-Saharan Africa.

INTRODUCTION: Our study assessed the efficacy of blended learning, which combines in-person learning and e-learning, in a pediatric scoliosis training program through an international collaborative effort. METHODS: The course comprised two parts: the online portion, where participants reviewed educational materials for 3 weeks and met with faculty once/week for discussion, and the in-person session, where participants reviewed cases in a team-based approach and came to a consensus on treatment strategy, followed by discussion with an international expert. All participants completed a needs assessment (NA) and clinical quiz at three points: before the course, after the online session, and after the in-person session, which covered various topics in pediatric spine deformity. RESULTS: Thirty-six surgeons enrolled in the course from 13 College of Surgeons of East, Central and Southern Africa countries. The NA assessment scores improved significantly over the course of the surveys from 67.3, to 90.9, to 94.0 (P = 0.02). The clinical quiz scores also improved from 9.91, to 11.9, to 12.3 (P = 0.002). CONCLUSION: The blended learning approach in a pediatric spine deformity program is effective and feasible and shows a statistically significant change in participants' confidence and knowledge base in these complex pathologies. This approach should be explored further with larger numbers and/or other spinal pathologies.

Evaluating the Feasibility and Outcomes of a Scoliosis Surgical Camp in a Resource-Limited Setting in Sub-Saharan Africa.

BACKGROUND: In sub-Saharan Africa, the estimated prevalence of scoliosis ranges from 3.3% to 5.5%. The management of these deformities is restricted due to lack of infrastructure and access to deformity spine surgeons. Utilizing surgical camps has been demonstrated to be efficient in transferring skills to low-resource environments; however, this has not been documented concerning deformity surgery. METHODS: We conducted a cross-sectional study. The scoliosis camp was held at a major referral spine center in East Africa. We documented information about the organization of the course. We also collected clinical and demographic patient data. Finally, we assessed the knowledge and confidence among surgeon participants on the management scoliosis. RESULTS: The camp lasted 5 days and consisted of lectures and case discussions, followed by casting and surgical sessions. Five patients were operated during the camp. All the patients in the study were diagnosed with AIS, except one with a congenital deformity. The primary curve in the spine was in the thoracic region for all patients. Six months postoperative Scoliosis Research Society-22R Scoring System (SRS-22R) score ranged from 3.3-4.5/5. 87.5% of the participants found the course content satisfactory. CONCLUSIONS: To the best of our knowledge, this is the first time an African scoliosis camp has been established. The study highlights the difficulty of conducting such a course and illustrates the feasibility of executing these complex surgeries in a resource-limited environment.

Operative Treatment of Traumatic Spinal Injuries in Tanzania: Surgical Management, Neurologic Outcomes, and Time to Surgery.

STUDY DESIGN: Retrospective case series. OBJECTIVE: Little is known about operative management of traumatic spinal injuries (TSI) in low- and middle-income countries (LMIC). In patients undergoing surgery for TSI in Tanzania, we sought to (1) determine factors involved in the operative decision-making process, specifically implant availability and surgical judgment; (2) report neurologic outcomes; and (3) evaluate time to surgery. METHODS: All patients from October 2016 to June 2019 who presented with TSI and underwent surgical stabilization. Fracture type, operation, neurologic status, and time-to-care was collected. RESULTS: Ninety-seven patients underwent operative stabilization, 23 (24%) cervical and 74 (77%) thoracic/lumbar. Cervical operations included 4 (17%) anterior cervical discectomy and fusion with plate, 7 (30%) anterior cervical corpectomy with tricortical iliac crest graft and plate, and 12 (52%) posterior cervical laminectomy and fusion with lateral mass screws. All 74 (100%) of thoracic/lumbar fractures were treated with posterolateral pedicle screws. Short-segment fixation was used in 86%, and constructs often ended at an injured (61%) or junctional (62%) level. Sixteen (17%) patients improved at least 1 ASIA grade. The sole predictor of neurologic improvement was faster time from admission to surgery (odds ratio = 1.04, P = .011, 95%CI = 1.01-1.07). Median (range) time in days included: injury to admission 2 (0-29), admission to operating room 23 (0-81), and operating room to discharge 8 (2-31). CONCLUSIONS: In a cohort of LMIC patients with TSI undergoing stabilization, the principle driver of operative decision making was cost of implants. Faster time from admission to surgery was associated with neurologic improvement, yet significant delays to surgery were seen due to patients' inability to pay for implants. Several themes for improvement emerged: early surgery, implant availability, prehospital transfer, and long-term follow-up.

Prevalence of spine surgery navigation techniques and availability in Africa: A cross-sectional study.

BACKGROUND: Africa has a large burden of spine pathology but has limited and insufficient infrastructure to manage these spine disorders. Therefore, we conducted this e-survey to assess the prevalence and identify the determinants of the availability of spine surgery navigation techniques in Africa. MATERIALS AND METHODS: A two-part questionnaire was disseminated amongst African neurological and orthopedic surgery consultants and trainees from January 24 to February 23, 2021. The Chi-Square, Fisher Exact, and Kruskal-Wallis tests were used to evaluate bivariable relationships, and a p-value <0.05 was considered statistically significant. RESULTS: We had 113 respondents from all regions of Africa. Most (86.7 %) participants who practiced or trained in public centers and centers had an annual median spine case surgery volume of 200 (IQR = 190) interventions. Fluoroscopy was the most prevalent spine surgery navigation technique (96.5 %), followed by freehand (55.8 %), stereotactic without intraoperative CT scan (31.9 %), robotic with intraoperative CT scan (29.2 %), stereotactic with intraoperative CT scan (8.8 %), and robotic without intraoperative CT scan (6.2 %). Cost of equipment (94.7 %), lack of trained staff to service (63.7 %), or run the equipment (60.2 %) were the most common barriers to the availability of spine instrumentation navigation. In addition, there were significant regional differences in access to trained staff to run and service the equipment (P = 0.001). CONCLUSION: There is a need to increase access to more advanced navigation techniques, and we identified the determinants of availability.
