The present invention relates to a perforation information processing method and device for a bone scaffold model. The method includes: step S1: importing a nonporous-bone-scaffold initial model; step S2: segmenting the nonporous-bone-scaffold initial model into a plurality of unit lattices according to an input signal; and step S3: perforating each of the unit lattices, to obtain a porous bone scaffold model. Compared with the related art, in the present invention, users have great autonomy in design and can completely customize the lattice structure, and the core computation steps can be highly parallelizable, which can greatly reduce the time required for computation.

A system for customizing an implant is provided. The system includes a processor configured to: i) obtain one or more medical image stacks of a joint; ii) obtain a three-dimensional image representation of the joint based on at least one of said medical image stacks; iii) determine damage to the joint by analyzing said medical image stacks; iv) select an implant template from a predefined set of implant templates having predetermined types and sizes; v) generate a 3D model, in which the marked damage is visualized together with the selected implant template in a proposed position; vi) display the 3D model; vii) receive an approval for said selected implant template in said proposed position; and viii) determine the final shape and dimensions of a customized implant based on said selected implant template and said proposed position.

Stemless components and fracture stems for joint arthroplasty, such as shoulder arthroplasty, are disclosed. Also, methods and devices are disclosed for the optimization of shoulder arthroplasty component design through the use of medical imaging data, such as computed tomography scan data.

A surgical navigation module comprising: (a) a microcomputer; (b) a tri-axial accelerometer; (c) a tri-axial gyroscope; (d) at least three tri-axial magnetometers; (e) a communication module; (f) an ultrawide band transceiver; and, (g) at least four ultrawide band antennas.

This disclosure describes manufacturing of a device configured to guide bone and tissue regeneration for a bone defect. A method may include receiving a three-dimensional digital model or scan representing an anatomical feature to be repaired, generating a simulated membrane using the three-dimensional model, the simulated membrane being configured to cover the anatomical feature to be repaired, generating a digital two-dimensional flattened version of the simulated membrane, and generating code or instructions configured to cause a three-dimensional printer or milling device to produce a trimming guide that includes an opening corresponding to the flattened version of the simulated membrane and that further includes a cut-out configured to hold a premanufactured membrane. The trimming guide may be operative as a guide for marking or cutting the premanufactured membrane through the opening while the premanufactured membrane is held in the cut-out.

An apparatus for forming a flowable material against a prosthetic implant can comprise a mold body having an outer surface and an inner surface. The inner surface can define a mold cavity that is selectively configured to at least partially accept the prosthetic implant in a forming position. An inlet port can be configured on the mold cavity that extends between the inner and outer surfaces. The mold cavity can substantially conform to a profile of a bone opposing surface of the prosthetic implant such that a void is created between the inner surface of the mold body and the bone opposing surface of the prosthetic implant. The inlet port can be configured to permit introduction of the flowable material into the void and against the bone opposing surface of the prosthetic implant.

A system for repairing a glenoid defect of a specific patient can include a patient-specific punch and a patient-specific shaping block. The patient-specific punch can form a patient-specific glenoid implant from a bone puck. The patient-specific shaping block can shape the patient-specific glenoid implant to match and fill a glenoid defect of a specific patient.
