Disclosed herein are a joint distractor for joint distraction and a method for utilizing the same in a joint distraction procedure. The joint distractor may include a first surface and a second surface. The first surface may contact a first bone of a joint and the second surface may contact a second bone of a joint. The first surface may be a flexible surface that is substantially parallel to the second surface in a first position and forms an arch in a second position to distract the first bone from the second bone. A method for distracting a joint may utilize the first and second surfaces of the joint distractor.

A method for assessing a joint includes inserting a joint distraction lever into a space between a first bone and a second bone of the joint, distracting the joint with the joint distraction lever, determining, using a measurement device of the joint distraction lever, a distraction force applied by the joint distraction lever as the joint distraction lever is used to distract the joint, determining whether the distraction force matches a predetermined amount of the distraction force, and in response to determining that the distraction force matches the predetermined amount of the distraction force, capturing first poses of the first bone and the second bone.

A distraction frame includes a table mount for removably mounting the distraction frame to a surgical table; at least one horizontal strut mounted to the table mount; at least one vertical strut mounted to the at least one horizontal strut; and at least one distractor mounted to the at least one vertical strut, wherein the at least one distractor is configured for connection to a limb of a patient and for applying a distraction force to the limb of the patient; wherein the table mount comprises at least one wheel for selectively supporting the table mount above the floor and the at least one horizontal strut comprises at least one caster for selectively rollably supporting the at least one horizontal strut on the floor so that the distraction frame can be selectively moved to the surgical table supported by the at least one wheel and the at least one caster.

A knee joint distractor includes a handle that has a length that extends along a longitudinal axis of the knee joint distractor and a distraction head connected to the handle. The distraction head has a femoral contact side and a tibial contact side. The femoral contact side has a first femoral contact portion. The tibial contact side has first and second tibial contact portions. The first tibial contact portion defines an inferior apex of the tibial contact side. The second tibial contact portion has a plurality of teeth offset from the inferior apex in a direction toward the handle.

A combination of a first assembly for guiding resection of a femur and tibia of a knee joint and a second assembly including femoral and tibial knee components. The combination of the first assembly and the second assembly provides optimal placement and positioning of the femoral and tibial knee components to achieve near-normal knee kinematics and tension. The preparation for and placement of the prosthetic knee components provides medial-pivoting kinematics mimicking that of the natural knee thereby promoting improved outcome for the patient.

The present disclosure provides a glenoid implant system for a reverse shoulder implant system that includes a glenoid implant having a center post, and also includes an angled baseplate comprising a bone facing surface to face an implant site prepared in a glenoid region of a patient, and an implant facing surface to face and engage the glenoid implant and receive the center post of the glenoid implant, wherein the implant facing surface being at an angle with respect to a centerline of the bone facing surface.

A joint tensioning device and methods of use thereof are disclosed. The joint tensioning device includes a flexing arm and a loading arm having a tensioning tip and a loading tip, respectively, configured for insertion into a joint. The flexing arm is coupled to the loading arm such that, during use, the loading arm may be adjusted to separate the tensioning tip and the loading tip to apply a distraction force to the joint. A strain gauge measures strain applied to the flexing arm based on the applied distraction force. The measured strain is used to determine the amount of force applied to the joint. The force data is employed in surgical planning to determine the amount of joint laxity when a particular load is applied to the joint.

Disclosed herein are apparatuses and methods for performing joint balancing procedures. The apparatus may have femoral paddle and a tibial paddle attached to a housing. The housing may include a distraction mechanism to vary the space between the femoral paddle and the tibial paddle. The tibial paddle may lie entirely within the femoral paddle in a closed position. A load sensor may be placed in the femoral paddle to measure ligament tension. The apparatus may be inserted into a knee joint and positioned to remain within the knee joint during flexion and extension of the knee without everting a patella.

A diameter sizing tool for use in reversion of total knee arthroplasty, the diameter sizing tool including a body having an upper surface, a lower surface, and a peripheral edge, a central cutout disposed through the body from the upper surface to the lower surface, and a plurality of sizing through-holes circumferentially disposed in the body and radially towards the peripheral edge.

A knee gap tensioning apparatus includes: a tensioner-balancer, including: a baseplate; a top plate; and a linkage operable to move the top plate relative to the bottom plate between retracted and extended positions in response to application of an actuating force, the linkage including: a first toggle linkage, including: a lower link having a first end pivotally connected to the baseplate; an upper link having a first end pivotally connected to the top plate, wherein second ends of the first and second links are pivotally connected to each other; a second toggle linkage, including: a lower link having a first end pivotally connected to the baseplate; an upper link having a first end pivotally connected to the top plate, wherein second ends of the first and second links are pivotally connected to each other; and a connector linkage interconnecting the first and second toggle linkages.
