A low-profile intercranial device including a low-profile static cranial implant and a functional neurosurgical implant. The low-profile static cranial implant and the functional neurosurgical implant are virtually designed and interdigitated prior to physical assembly of the low-profile intercranial device.

Methods, systems and devices for pre-operatively planned total or partial joint surgery including, for example, anatomic and reverse shoulder surgery guides and implants. There are also methods for pre-operative planning methods for designing glenoid implants and prostheses, particularly with patient-specific augmentation, based on considerations of multiple factors affecting the outcome of a selected reverse or anatomic shoulder surgery. There are also described methods of performing total or partial joint surgery, including anatomic or reverse shoulder surgery, using surgery guides and implants in patients undergoing joint surgery.

A method for designing a two-part joint prosthesis (830) comprises: providing kinematic data of a subject's joint under load; and designing the joint prosthesis using the kinematic data, wherein the working surfaces of the two-part prosthesis comprise, consist essentially of or consist of cellular material. Advantageously, the method may not require any intra-operative adjustments to replace one or more of the components (831, 832), e.g. with a component of a different size. In particular, if components are made of biological tissues, such as a patient's own cells, it is advantageous to design and produce an implant that requires no adjustments intra-operatively as each implant may be manufactured specifically for each patient, and the time and costs of producing a range of sizes, most of which would not be required, would otherwise be prohibitive.

The invention relates to a method and a device for producing an implant, wherein a natural bone microstructure of a natural bone region is detected (S1), an implant region in the natural bone region is marked (S2), the detected bone microstructure in the marked implant region is analysed to determine reproduction parameters (S3), and on the basis of the determined reproduction parameters, an artificial microstructure for producing the implant is created (S4).

Techniques for fabrication of implant material for the reconstruction of fractured eye orbit may include using an image processing system to analyze a set of two-dimensional images representing a three-dimensional scan of a skull of a patient, automatically detect an orbital fracture in the skull based on the set of two-dimensional images, and identify which/both of the two eye orbits containing any orbital fracture. The techniques may further include, for each of the two-dimensional images in which the orbital fracture is detected, determining a region of interest, and extracting the region of interest. The techniques may further include generating a three-dimensional reconstruction model for the fractured eye orbit, and outputting model data for generating an implant mold for the fractured eye orbit.

Devices, systems, techniques and methods for determining the fit of an implant and for determining one or more prognosticators, indicators or risk factors of postoperative performance are provided.

Disclosed herein are a method and system for producing a digital model of a customised device, comprising the steps of: importing a first digital file of a base part; importing a second digital file of a target shape; determining a warping interpolation function based on source point positions associated with the base part and target point positions associated with the target shape; and applying the warping interpolation function to the points of said base part to generate a model of said customised device.

Patient-specific craniofacial implants structured for filling bone voids or planned bone voids in the cranium and face as well as for simultaneously providing soft tissue reconstruction and/or augmentation for improved aesthetic symmetry and appearance of face and skull. Pterional or temporal voids or defects generally result from a chronic skull or lateral facial deformity along with a compromised temporalis muscle or soft tissue distortion from previous surgery. When muscle and fat atrophy occurs in the pterion or temporal face, temporal hollowing deformity generally results where there would be soft tissue but for the atrophy. The patient-specific craniofacial implants with dual-purpose herein are configured to have an augmented region adjacent the temporal region of the face and cranium in order to prevent and/or correct any such temporal hollowing deformity and to utilize this newfound space to strategically embed implantable neurotechnologies for improved outcomes.

The present disclosure includes fixation devices, such as an orthopedic screw or implant, that comprises one or more porous elements or fenestrations to aid in osteo-integration of the fixation device. The fixation device may be additively manufactured using biocompatible materials such that the solid and porous aspects of the screw are fused together into a single construct. In yet another aspect, the fixation device comprises at least a portion or section incorporating a porous structure, which enables bony ingrowth through the porous section/portion of the screw, and thereby facilitates biocompatibility and improve mechanical characteristics. Methods for using the fixation device are also described herein.

An example system for designing a patient matched implant for an orthopedic joint repair surgical procedure includes a memory configured to store a model of a bone of a patient; and processing circuitry. The processing circuitry may be configured to: obtain the model of the bone of the patient; obtain a template model of an implant; determine a shape of a surface of the implant; determine a volume between the shape of the surface of the implant and a surface of the bone defined by the model of the bone; generate, based on the determined volume and the template model, a patient matched implant model; and output a file representing the patient matched implant model.
