Abstract:Novel three-dimensional preoperative planning, coupled with patient and implant-specific instrumentation, allows the surgeon to better define the preoperative pathology, select the optimal implant design and location, and then accurately execute the plan at the time of surgery.
“…In such cases, further surgical releases or a change in the type or location of retractors would be needed to obtain the necessary exposure to place the device. This requirement and limitation would also be relevant for the placement of any surgical tool, including patient-specific instrumentation 15 or tools associated with computer-guided surgical navigation 1-3 . In addition, the stereolithographic model containing the guide pin had the same morphology as the corresponding Sawbones patient model and neither contained any soft-tissue attachments.…”

“…Taken yet a step further, patient-specific instrumentation is now available for shoulder arthroplasty. 24 This technology allows all the navigation and templating decisions to be made preoperatively, and a patient-specific set of guides is generated. This appears to have the benefits of computer-navigated surgery without the added surgical time required for registration or the placement of markers in the scapula.…”
“…1,11,13,15,25,26,32 These have been shown to reflect the true anatomy more accurately, leading to more accurate component placement in TSA. 13,15 We showed that the 3D HSI is more reliable and accurate than the current 2D HSI.…”
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
