The present disclosure provides a bioresorbable foam closure device for trans-nasally closing an opening in a base of a skull. The closure device comprises a phase-separated polymer having a porosity of greater than 80%. The device includes a stem portion having a proximal end and a distal end, and a head portion at the distal end of the stem portion. The closure device is deformed from a free shape to a constricted shape, inserted through a nasal cavity and into the opening, and released to at least partially revert back to the free shape such that the stem portion fills the opening and the head portion abuts cranium and dura to secure the closure device in position and seal the opening.

An arthrodesis anchor as a monolithic piece has prongs supporting barbs extending radially therefrom. A neck between the ends may be angled to accommodate final alignment of resected surfaces of joints to be bonded. The neck may receive a tool for buttressing a first inserted end against further penetration into a joint while the second inserted end is inserted into the other adjacent joint. The proximal and intermediate phalangeal joints may be trimmed and pilot drilled, and may be broached with or without a K-wire guide. A first end may be inserted by a tool, typically into the proximal joint, but the order may be reversed. The second end may then be inserted into a pilot in the base of the intermediate joint.

In general, devices, systems, and methods for driving an anchor into bone are provided. In one embodiment, a surgical tool is provided that includes a driver tool with a handle and an elongate shaft. A resistance element is disposed within the handle. An inner portion of an anchor is retained on a distal end of the elongate shaft, and a guidewire extends between the resistance element and an outer portion of the anchor that is in bone. As force is applied distally to the handle, the guidewire pushes the anchor into the bone before overcoming force of the resistance element and thereby allowing the inner portion of the anchor to be driven into the outer portion of the anchor.

A tool useful for deploying a flip anchor connected to a cable includes a housing with a first end and a second end; and a guiding tube having a bore therethrough. The guiding tube has a proximal end releasably connected to the first end of said housing, and a distal end configured to hold said flip anchor. The housing includes a mechanism having a low resistance surface and a slider having a high friction surface facing the low resistance surface, where the slider is movable between a) a clamping position configured to clamp the cable between the low resistance surface and the high friction surface; and b) a release position configured to allow the cable to move freely on the low resistance surface. A safety button on said housing is movable between an elevated position where the safety button holds the slider in said first position, and a depressed position where the safety button releases the slider, allowing it to enter the second position. The slider is configured to move the cable distally upon movement from the clamping position to the release position, deploying the flip anchor from the guiding tube.

A lower limb traction device for intramedullary nail implantation operation includes a chassis with a first end portion and a second end portion opposite to each other; a first slide block slidably provided at a second end portion of the chassis in a longitudinal direction of the chassis; a lower leg support plate having two opposite end portions and two opposite side portions, wherein one end portion is connected to the first slide block; an upper leg back plate having opposite end portions and opposite side portions, wherein one end portion of the upper leg back plate is connected to the second end portion of the chassis, and the other end portion of the upper leg back plate is connected to the other end of the lower leg support plate; and a pulling mechanism provided at the first end portion of the chassis.

A medical device for implantation in a hip joint of a human patient, the natural hip joint having a ball shaped caput femur as the proximal part of the femoral bone with a convex hip joint surface towards the center of the hip joint and a bowl shaped acetabulum as part of the pelvic bone with a concave hip joint surface towards the center of the hip joint. The medical device comprising; an artificial caput femur, comprising a convex surface towards the center of the hip joint. The artificial convex caput femur is adapted to, when implanted: be fixated to the pelvic bone of the human patient, and be in movable connection with an artificial acetabulum surface fixated to the femoral bone of the patient, thereby forming a ball and socket joint. The medical device further comprises a fixation element comprising a fixation surface adapted to be in contact with the surface of the acetabulum and adapted to fixate the artificial convex caput femur to at least the acetabulum of the pelvic bone.

In one example, a system has an insertion handle that can be coupled to an intramedullary nail and includes a first coupler that defines one of a recess and a projection, and one of a latch and an abutment surface. The system has an aiming guide that includes a guide body that defines at least one alignment aperture therethrough. The aiming guide includes a second coupler that can couple the guide body to the first coupler such that the at least one alignment aperture is positioned to guide an instrument towards at least one bone-anchor fixation hole of the intramedullary nail. The second coupler defines another of the recess and the projection, and another of the latch and the abutment surface. The first and second couplers can couple to one another by receiving the projection in the recess and by engaging the latch with the abutment surface.

A spinal implant comprises an implant body extending between an anterior surface and a posterior surface, and including a first vertebral engaging surface and a second vertebral engaging surface. The implant body includes an inner surface that defines at least a first cavity and a second cavity. The cavities are oriented to implant fasteners in alignment with an oblique surgical pathway relative to a bilateral axis of a subject body and adjacent an anterior portion of an intervertebral space of the subject body. Systems and methods are disclosed.

A method of surgically treating a patient suffering from severe pain and disability of the low back and buttock by stabilizing the patient's spinal column to their pelvis with an implant system including surgical tools and an implant designed to prevent movement between the sacrum and the ilium while being able to attach to a spinal fusion rod which connect to pedicle screws implanted in the bones of the spine of the patient in order to offer lasting relief of the patient's symptoms. The system is designed to address complications in adult spinal deformity by optimizing spinopelvic fixation via-a-vis the unique biomechanics of the SI joint. The sacropelvic system is a surgical solution which provides an additively manufactured implant at the base of the spine employing an S2AI trajectory while utilizing assisting technologies including surgical navigation and intraoperative neurophysiological monitoring.

A multiple drive interference screw device with a head having multiple insertion features. The screw component has a tubular body with a first end and a closed second end, and the head is positioned at the first end and configured to engage with a driver to advance the screw into the bone A penetrating tip is positioned at the second end. The head of the screw component has at least three insertion features, such as a hex shaped insertion feature around the major diameter of the head and a hexalobe shaped insertion feature within the hex shaped insertion feature, and a sprocket shaped insertion feature positioned exterior to the hex shaped insertion feature.
