摘要： Illustrative methods and systems for customizing a pre-manufactured acetabular shell to a specific patient are described herein. An illustrative method can include positioning a provisional shell at an acetabulum of the patient, the provisional shell having a plurality of selectable openings. The method further including marking, based on the assessing of the bone, a patient-matched hole location on a provisional liner that corresponds to one of the plurality of selectable openings in the provisional shell. With the provisional liner marked, the method can further include removing the provisional liner from the provisional shell and positioning the provisional liner in the pre-manufactured acetabular shell that is to be implanted in the patient. Using the provisional liner as a guide, the method can include forming a hole in the acetabular shell corresponding to the marked patient-matched hole location on the provisional liner.

摘要： A ratcheting driver can be configured to selectively transmit a torque to a fastener. The driver can include a handle, a geared body, and a shaft. The handle can include a housing, a pawl, and a biasing element. The housing can include a central bore and a shaft bore extending through a distal portion of the housing. The pawl can extend radially inward from the housing into the central bore. The biasing element can engage the housing. The geared body can be rotatably engageable with the pawl to allow rotation of the geared body relative to the handle in a first direction and to limit rotation of the geared body relative to the handle in a second direction, where the biasing element can be engageable with the geared body to bias the geared body distally.

摘要： Various different porous screws and pegs are disclosed herein, as are methods of manufacturing such porous pegs or screws. The porous screws and pegs, in certain examples, are formed through additive manufacturing and have improved porosity for bone ingrowth. In certain cases, additive manufacturing or another manufacturing technique can be used to cover only part or all of the threads of the screws or pegs disclosed herein with a porous material. Such screws or pegs can have porosity but also threads that are capable of effectively digging into bone.

摘要： An orthopedic implant can comprise a structural body, a plug and a frangible connection. The structural body can comprise a first surface, a second surface opposing the first surface, and a through-bore extending from the first surface to the second surface. The through-bore can have a bore surface. The structural body can be formed of a porous material. The plug can be disposed in the through-bore. The frangible connection can link the bore surface and the plug. A method of manufacturing an orthopedic implant can comprise producing a porous structural body having a port, producing a plug for positioning in the port, and producing a plurality of frangible crosspieces within the port to connect the plug to the structural body.

摘要： A tool assembly for extracting a liner from a prosthesis comprising an impactor and a faceplate. The impactor can be configured to receive and transmit a force. The faceplate can be configured to deliver the force from the impactor to the prosthesis to separate the liner from a shell of the prosthesis.

摘要： A surgeon can place a bone perforator in contact with a bone, and can hammer on the bone perforator. The hammering can drive teeth on the bone perforator into the bone, thereby creating a perforation in the bone. The surgeon can pry or break the bone along the perforation, can access tissue beneath the bone as needed, and can replace the bone along the perforation. In some examples, the bone perforator is formed as a bendable sheet having teeth in a fixed, single-file pattern, with a hammerable surface opposite the teeth. In other examples, the bone perforator has repositionable teeth.

摘要： Systems and methods and augments for supporting an acetabular shell at a hip bone. An example system of modular augments can include first and second augments, each having a body extending from a respective first end portion to a respective second end portion. The first augment second end portion can include a first coupling element and the second augment first end portion can include a second coupling element. Together the first and second coupling elements can form a coupling mechanism to join the first and second augments together. In some examples, the coupling mechanism can include a bulbous tip portion and a recess to receive and retain the bulbous tip portion.
