OBJECTIVE: We sought to examine the role of halo gravity traction (HGT) in reducing preoperative surgical risk. SUMMARY OF BACKGROUND DATA: The impact of HGT on procedure choice, preoperative risk factors, and surgical complications has not been previously described. METHODS: Patients treated with HGT before primary surgery were included. The FOCOS Score (FS) was used to quantify operative risk. FS was calculated using patient-factors (ASIA, body mass index, etiology), procedure-factors (PcF; osteotomy planned, number of levels fused, etc.), and curve magnitude (CM). Scores ranged from 0 to 100 with higher scores indicating increased risk. FS was calculated before and after HGT to see how changes in FS affected complication rates. RESULTS: A total of 96 patients were included. Halo-related complications occurred in 34% of patients but revision was required in only 8.3%. Average FS improved by 18 points after HGT. CM, PcF, and patient-factors all improved (P < 0.05). The greatest changes were in CM and PcF. The planned rate of three-column osteotomies dropped from 91% to 38% after HGT. FS (area under the curve [AUC]: 0.68, P = 0.023) and change in FS (AUC: 0.781, P < 0.001) was successfully able to predict the rate of surgical complications. A preoperative FS of 74 was identified as a cut-off for a higher rate of surgical complications (sensitivity 58.8%, specificity 74.7%). Patients with a reduction in FS < = 10pts were five times more likely to have a complication (relative risk 5.2, 95% confidence interval: 1.9-14.6, P < 0.001). A multivariate regression showed that change in FS was an independent predictor of complication rates (P < 0.05). CONCLUSION: FS can successfully predict surgical risk in pediatric patients with complex spinal deformity. Preoperative HGT can reduce FS and surgical risk by improving CM, lowering three-column osteotomies use, and improving body mass index. A reduction in FS after HGT predicts a lower rate of surgical complications. LEVEL OF EVIDENCE: 3.Item Ileal stricture following strangulated inguinal hernia.(2007-10-01) Dakubo, J. C. B; Akoto, H.; Etwire, V. K.; Naaeder, S. B.Small intestinal stenosis due to ischaemia following strangulated hernia is uncommon as patients with external hernias have ready access to elective herniorrhaphy. Small intestinal stenosis secondary to ischaemiamay lead to acute small bowel obstruction, acute-on-chronic obstruction or chronic small bowel obstruction. Itmay also give rise to the blind loop syndrome. Preoperative diagnosis of this condition is difficult.We report four cases of small intestinal stenosis who presented to one surgical unit at the Korle-BuTeaching Hospital with acute intestinal obstruction over a period of 15 months.Item Pattern of intracranial tumours in a tertiary hospital in Ghana(Ghana medical journal, 2018-06) Ekpene, U.; Ametefe, M.; Akoto, H.; Bankah, P.; Totimeh, T.; Wepeba, G.; Dakurah, T.Objective: This study seeks to describe the pattern of intracranial tumours in Korle Bu Teaching Hospital (KBTH) based on patient demographics, clinical presentation, spatial distribution of tumour and histological findings. Method: The study design is retrospective and descriptive. Data was obtained from the clinical records of patients with intracranial tumours treated in our neurosurgery unit between January 2010 to December 2015, and histology reports obtained from the histopathology unit. Patients with intracranial tumours without definitive histological diagnosis were excluded. Results: Of the 102 histologically diagnosed brain tumours, out of 335 brain tumour cases seen in the period under review, 58 (56.9%) were females and 44 (43.1%) were males (p = 0.031). Gliomas were the commonest intracranial tumours - 39(38.2%) followed by Meningiomas 37(36.2%) and Pituitary Adenoma - 9(8.8%). Astrocytoma was the commonest type of Glioma comprising 30(77%) of the 39 cases. Meningotheliomatous meningioma was the commonest type of meningioma with 11 (29.7%) of 37 cases. Of the 39 Gliomas 17(43.6%) were males and 22(56.4%) were females, while for the Meningioma 17(46%) were males and 20(54%) were females. The commonest symptom was headache (64%) and the commonest tumour location was supratentorial (77.5%). The crude incidence rate of intracranial tumours in this study was 1.34 per 100,000 populations per year. Conclusion: Gliomas are the commonest intracranial tumours seen in our series. Overall, females were more commonly affected than males in most brain tumours in this series, including both gliomas and meningiomas.

To describe the feasibility of preoperative halo gravity traction (HGT) with subsequent growing rod/guided growth (GR/GG) placement in early onset spinal deformity (EOSD). Summary of Background Data. In children with severe EOSD, primary implantation of GR/GG constructs is not always possible. We describe a staged protocol with preoperative HGT followed by GR/GG implantation. Methods. EOSD patients treated with HGT prior to GR/GG implantation were included. HGT used traction up to 50% body weight for 4 to 29 weeks. Pulmonary function tests (PFTs) were performed before and after HGT. Coronal Cobb (CC) and Sagittal Cobb (SC) angles were measured on the Pre-HGT, Post-HGT and 6 week postop x-rays. Results. Thirty patients were included. Average age at GR/GG implantation was 9 years. Most cases (n = 24, 80%) were idiopathic. Most pts had kyphoscoliosis (n = 16, 53.3%). Pre-HGT CC averaged 112 ± 22° and SC averaged 106 ± 26°. CC and SC improved 29% after HGT. There was a significant improvement in body mass index following HGT. CC improved further to 70 ± 14° (36% vs. pre-HGT) and SC to 63 ± 21° (41%) with GR/GG placement. HGT-related complications occurred in nine patients (30%); eight pin site infections, one cranial abscess. Most HGT complications were managed with local pin care and oral antibiotics. Halo revision was required in two pts (6.7%). There was no change in PFTs with HGT (P > 0.05). Averagely, 14 levels were spanned during GR/GG implantation; two patients required vertebral column resection. Surgical complications occurred in nine (30%) patients. At average 16 month follow-up, seven patients (23.3%) required reoperation. Conclusion. Preoperative HGT can make severe EOSD curves amenable to GR/GG implantation. HGT results in ∼30% correction with improvement to ∼35–40% following GR/GG. HGT has a 30% complication rate but most are pin-site infections managed with pin-site care and oral antibiotics; 6.7% of patients require revision
