Single-event multilevel surgery (SEMLS) is the standard orthopaedic treatment for gait abnormalities in children with diplegic cerebral palsy (CP). The primary aim of this study was to report the long-term functional mobility of these patients after surgery. The secondary aim was to assess the relationship between functional mobility and quality of life (QoL). Patients were included if they met the following criteria: 1) diplegic CP; 2) Gross Motor Function Classification System (GMFCS) I to III; 3) SEMLS at age ≤ 18. A total of 61 patients, mean age at surgery 11 years eight months (SD 2y 5m), were included. A mean of eight years (SD 3y 10m) after SEMLS, patients were contacted and asked to complete the Functional Mobility Scale (FMS) questionnaire over the telephone and given a weblink to complete an online version of the CP QOL Teen. FMS was recorded for all patients and CP QOL Teen for 23 patients (38%).Abstract

Accurate orientation of the acetabular component during a total hip replacement is critical for optimising patient function, increasing the longevity of components, and reducing the risk of complications. This study aimed to determine the validity of a novel VR platform (AescularVR) in assessing acetabular component orientation in a simulated model used in surgical training. The AescularVR platform was developed using the HTC Vive® VR system hardware, including wireless trackers attached to the surgical instruments and pelvic sawbone. Following calibration, data on the relative position of both trackers are used to determine the acetabular cup orientation (version and inclination). The acetabular cup was manually implanted across a range of orientations representative of those expected intra-operatively. Simultaneous readings from the Vicon® optical motion capture system were used as the ‘gold standard’ for comparison. Correlation and agreement between these two methods was determined using Bland-Altman plots, Pearson's correlation co-efficient, and linear regression modelling.Abstract
