Hurst SA, Merlini L, Hansen U, Gregory J, Emery R, Gregory Tet al., 2021, The Glenoid Vault Outer Cortex a new more accurate radiological reference for shoulder arthroplasty, SICOT-J, Vol: 7, Pages: 32-32

<jats:p><jats:italic>Introduction</jats:italic>: Correct positioning of the glenoid component is an important determinant of outcome in shoulder arthroplasty. We describe and assess a new radiological plane of reference for improving the accuracy of glenoid preparation prior to component implantation – the Glenoid Vault Outer Cortex (GvOC) plane. <jats:italic>Methods</jats:italic>: One hundred and five CT scans of normal scapulae were obtained. Forty six females and 59 males aged between 22 and 30 years. The accuracy of the GvOC plane was then compared against the current “gold standard” – the scapular border (SB). Measurements of glenoid inclination, version, rotation, and offset were obtained using both the GvOC and SB planes. These were then compared to actual values. <jats:italic>Results</jats:italic>: The mean difference between version obtained using the GvOC plane and the actual value was 1.8° (−2 to 5, SD 1.6) as compared to 6.7° (−2 to 17, SD 4.3) when the SB plane was used, (<jats:italic>p</jats:italic> &lt; 0.001). The mean difference between estimates of inclination obtained using the GvOC plane and the actual were 1.9° (−4 to 6, SD 1.6) as compared to 11.2° (−4 to 25, SD 6.1) when the SB plane was used, (<jats:italic>p</jats:italic> &lt; 0.001). <jats:italic>Conclusions</jats:italic>: The GvOC plane produced estimates of glenoid version and inclination closer to actual values with lower variance than when the SB plane was used. The GvOC may be a more accurate and reproducible radiological method for surgeons to use when defining glenoid anatomy prior to arthroplasty surgery.</jats:p>

Darwood A, Hurst S, Villatte G, Fenton R, Tatti F, El-Daou H, Reilly P, Emery R, Rodriguez Y Baena Fet al., 2019, Towards a commercial system for intraoperative manufacture of patient-specific guides for shoulder arthroplasty, CAOS 2019. The 19th Annual Meeting of the International Society for Computer Assisted Orthopaedic Surgery, Publisher: EasyChair, Pages: 110-114

The accurate placement of orthopaedic implants according to a biomechanically derived preoperative plan is an important consideration in the long-term success of these interventions. Guidance technologies are widely described however, high cost, complex theatre integration, intraoperative inefficiency and functional limitations have prevented the widespread use. A novel, intraoperative mechatronics platform is presented, capable of the rapid, intraoperative manufacture of low-cost patient-specific guides. The device consists of a tableside robot with sterile drapes and some low cost, sterile disposable components. The robot comprises a 3D optical scanner, a three-axis sterile computer numerical control (CNC) drill and a two-axis receptacle into which the disposable consumables may be inserted. The sterile consumable comprises a region of rapidly setting moldable material and a clip allowing it to be reversibly attached to the tableside robot. In use, patient computed tomography (CT) imaging is obtained at any point prior to surgery and a surgical plan is created on associated software. This plan describes the axis and positioning of one or more guidewires which may, in turn, locate the prosthesis into position. Intraoperatively, osseous anatomy is exposed, and the sterile disposable is used to rapidly create a mould of the joint surface. Once set, the mould is inserted into the robot and an optical scan of the surface is taken followed by automatic surface registration, bringing the optical scan into the same coordinate frame of reference as the CT data and plan. The CNC drill is orientated such that the drill axis and position exactly matches the planned axis and position with respect to the moulded surface. A guide hole is drilled into the mould blank, which is removed from the robot and placed back into the patient with the moulded surface ensuring exact replacement. A wire is subsequently driven through the guide hole into the osseous anatomy in accordance with

Hurst S, 2017, Electronic patient centred outcomes in orthopaedic surgery

This thesis primarily reports on the national pilot of an electronic patient reported outcomes (ePRO) system for orthopaedic patients. Also reported on within the pilot is a new electronic patient centred outcome measure (ePCO) with focus on activity participation, and aspiration. At the time of publishing the pilot remains the largest of its kind within the speciality, and the first of its kind with respect to ePCOs. A background with historical perspective is provided for the use of outcomes in orthopaedic surgery, including a discussion surrounding current practices, and controversies. The engineering principles behind the construction of an ePCO/PCO system are also explained, along with the current regulatory guidelines governing them in Europe and the United States. The development and piloting of three individual software platforms are explained, evaluated, and discussed. This includes in the appendix a discussion on their wider context within industry, and within an increasingly technological able society. The final platform (Software C) is piloted in a large cohort both nationally, and internationally. Results from the pilot are presented and discussed in terms of the software usability, the ability for PROs to be successfully digitalised to ePROs within the software, and patient’s opinion of the technology. Objective outcome data obtained from a instrumented treadmill is used as an adjunct to the analysis of the impact of ePROs collected during the pilot, and also helping to address the validation parameters for the ePCO. Finally, the PCO is reported on. This includes the principles providing its conception, and foundation. It is tested using parameters for outcome score validation in both an initial paper-based pilot study, and in a national pilot using a modified digitalised format of the PCO
