Background: The SARS-CoV-2 pandemic has had profound implications on healthcare institutions., Aims: This study aims to assess and compare referral patterns during COVID-19 to corresponding dates for the preceding 3 years (2017-2019), in order to preemptively coordinate the logistics of the surgical unit for similar future experiences., Methods: Retrospective review for our institution, a national tertiary referral centre for spine pathology. Two distinct time-points were chosen to represent the varied levels of social restriction during the current pandemic: (i) study period 1 (SP1) from 11 November 2020 to 08 June 2020 represents a national lockdown, and (ii) study period 2 (SP2) from 09 June 2020 to 09 September 2020 indicates an easing of restrictions. Both periods were compared to corresponding dates (CP1: 11 March-08 June and CP2 09 June-09 September) for the preceding 3 years (2017-2019). Data collected included age, gender, and mechanism of injury (MOI) for descriptive analyses. MOIs were categorised into disc disease, cyclist, road-traffic-accident (RTA), falls < 2 m, falls > 2 m, malignancy, sporting injuries, and miscellaneous., Results: All MOI categories witnessed a reduction in referral numbers during SP1: disc disease (-29%), cyclist (-5%), RTAs (-66%), falls < 2 m (-39%), falls > 2 m (-17%), malignancy (-33%), sporting injuries (-100%), and miscellaneous (-58%). Four of 8 categories (RTAs, falls < 2 m, malignancy, miscellaneous) showed a trend towards return of pre-lockdown values during SP2. Two categories (disc disease, falls > 2 m) showed a further reduction (-34%, -27%) during SP2. One category (sporting injuries) portrayed a complete return to normal values during SP2 while a notable increase in cyclist-related referrals was witnessed (+ 63%) when compared with corresponding dates of previous years., Conclusion: Spinal injury continues to occur across almost all categories, albeit at considerably reduced numbers. RTAs and falls remained the most common MOI. Awareness needs to be drawn to the reduction of malignancy-related referrals to dissuade people with such symptoms from avoiding presentation to hospital over periods of social restrictions., (© 2021.

Background: Adolescent idiopathic scoliosis (AIS), with an incidence of 3%, is a common deformity. Correction of severe curvature of the deformity has attracted much investigation to achieve safe, reproducible results. We present our experience with a novel device for the correction of deformities across a spectrum of curve types, the rod link reducer. This system allows direct visualization of a mass derotation to achieve deformity correction., Methods: Prospective cohort study of patients with severe AIS treated in our institution during 2017 with major TL/L curves. Pre- and postoperative Cobb angles and coronal balance; operative time; and estimated blood loss, fusion levels, and screw density were recorded. Our results were split between those with a Lenke A/B classification and Lenke C, with a goal of correction of curve in the former and achieving good coronal balance with a preservation of distal motion segments in the latter., Results: There were 31 patients enrolled in our series. Within the Lenke A/B group, there were 18 patients, achieving a mean correction of 56% (SD 10%) and a correction of a mean coronal balance of 14.5 mm (SD 12.5 mm) of C7 from the CSVL to 10.9 mm (SD 10.6 mm). Our screw density was 1.3 screws (SD 0.1) per vertebrae fused. Our operative time was 185 min (SD 38 min). Average recorded blood loss was 721 ml (SD 289). In our Lenke C cohort, preoperative and postoperative mean Cobb angles (SD) were 73.3 (13.4) and 33.8 (11.9), respectively, with an average correction of 54% (SD 11%). The mean (SD) operative time was 03:35 (SD 00:35). Fusion levels were over a mean of 12.1 (SD 1.7) vertebrae, with a screw density of 1.3 (SD 0.1) per level. Mean intraoperative blood loss was 829 ml (SD 355). No patient received an allogenic blood transfusion. There were no adverse neurological events in this patient cohort., Conclusions: The link rod system allows for excellent correction of spinal deformity and a short operative time.

Background: Culture yield in osteomyelitis and septic arthritis is low, emphasising the role for molecular techniques., Aims: The purpose of this study was to review the laboratory investigation of childhood osteomyelitis and septic arthritis., Methods: A retrospective review was undertaken in an acute tertiary referral paediatric hospital from January 2010 to December 2016. Cases were only included if they had a positive culture or bacterial PCR result from a bone/joint specimen or blood culture, or had radiographic evidence of osteomyelitis., Results: Seventy-eight patients met the case definition; 52 (66%) were male. The median age was 4.8 years. Blood cultures were positive in 16 of 56 cases (29%), with 11 deemed clinically significant (Staphylococcus aureus = 8, group A Streptococcus = 3). Thirty-seven of 78 (47%) bone/joint samples were positive by culture with S. aureus (n = 16), coagulase-negative Staphylococcus (n = 9) and group A Streptococcus (n = 4), being the most common organisms. Sixteen culture-negative samples were sent for bacterial PCR, and four were positive (Kingella kingae = 2, Streptococcus pneumoniae = 1, group A Streptococcus = 1)., Conclusions: Sequential culture and PCR testing can improve the detection rate of causative organisms in paediatric bone and joint infections, particularly for fastidious microorganisms such as K. kingae. PCR testing can be reserved for cases where culture is negative after 48 h. These results have been used to develop a standardised diagnostic test panel for bone and joint infections at our institution.

Study Design: This article presents a case of Paget's disease of the cervical spine., Objectives: To report a very rare case of Paget's disease of the cervical spine and review the literature., Methods: We report a case of Paget's disease of the cervical spine in a 51-year-old male presenting with neck pain post RTA. Routine radiographs revealed enlarged sclerotic bodies of C2-C5 with normal alignment. CT revealed a fracture of the lateral mass of C2 with extensive sclerotic changes in the bodies of C2-C5 with periosteal apposition, endosteal resorption "pumice stone" type focal periosteal apposition consistent with Paget's disease. Laboratory investigations were consistent with a diagnosis of Paget's disease. Isotope bone scan revealed isolated uptake in the cervical spine. He was commenced on biosphosphonate therapy. Following 12 weeks of immobilisation his orthosis was removed and rehabilitation commenced., Results: At 12-month follow-up he is asymptomatic with no radiological change., Conclusion: This case illustrates the investigation and successful management of a very rare case of Paget's disease of the cervical spine.
