Bone deformity correction devices and methods of using such devices to correct bone deformities. The device can include an elongate body, an adjustable manipulation arm movably coupled to the elongate body, wherein the adjustable manipulation arm is configured to move axially and laterally, and a cutting guide removably attachable to the device elongate body.

The present invention concerns a reusable surgical guide for osteosynthesis surgery, forming an aimer for guiding and inserting axial wires into bone portions; said guide comprises a grip constituted by a head extending at the upper end of a base, a trigger adapted to be displaced in a first slide formed in the head of the grip and whose distal end is provided with a through hole for the insertion of a wire, a blade secured to the distal end of the head of the grip, under the trigger, and a so-called aiming piece adapted to be displaced in a second slide formed in the base of the grip, said aiming piece comprising at the distal end thereof means for supporting at least one wire.

Spinal correction surgical techniques and methodologies for correction of scoliosis using non fusion anterior scoliosis correction, including soft tissue releases, unique correction techniques such as de-rotation, and unique single and dual anchor screw/cord applications.

Devices and techniques for adjusting an alignment for a first metatarsal may include making a plurality of cuts along the length of the first metatarsal. In different applications of the technique, a plurality of transverse cuts may or may not be made intersecting the longitudinal cuts. In either case, the cuts can separate the first metatarsal into two individual portions and release a removable wedge of bone. The different portions of the metatarsal can be moved relative to each other to adjust an anatomical alignment of one portion relative to another portion, for example in multiple planes. After suitably adjusting the alignment of the different bone portions, the portions can be fixed together.

The present application provides a total knee arthroplasty robot auxiliary system, a control method, electronic device and a computer readable medium. The auxiliary system comprises: a preoperative planning system configured to formulate a preoperative plan, preoperative plan data including a knee joint image; an intraoperative planning system configured to formulate an intraoperative plan, wherein the knee joint image in the preoperative plan and a knee joint surface contour of the patient determined in an operation are subjected to image registration, knee joint dynamic spacing force line data at a continuous flexion-extension angle is acquired, a dynamic spacing force line data graph is visually displayed, and a prosthesis plan is adjusted according to the visual display of the dynamic spacing force line data graph to obtain the intraoperative plan; and an executing system, wherein a bone-cutting guide mounted at an operating end of a mechanical arm of a surgical robot is guided to be located in a planned predetermined position according to the intraoperative plan, and the bone-cutting guide is configured to locate a bone-cutting saw.

A metatarsal alignment apparatus and methods are provided for orienting and maintaining a 1st metatarsal bone in a natural anatomical position during surgical procedures for treating a hallux valgus deformity by way of arthrodesis of the 1.sup.st metatarsocuneiform joint. The metatarsal alignment apparatus includes a cuneiform block for pinning a cuneiform bone and a distal metatarsal block for pinning a 1.sup.st metatarsal bone. The cuneiform block is threadably engaged with a shaft for moving the cuneiform block longitudinally with respect to the distal metatarsal block. The distal metatarsal block is adjustable within a distal frame to facilitate moving transversely and rotating the 1.sup.st metatarsal bone with respect to the cuneiform bone. The distal metatarsal block may be fixated by way of a lock screw to fixate the orientation of the 1.sup.st metatarsal bone with respect to the cuneiform bone during preparing the 1.sup.st metatarsocuneiform joint for arthrodesis.

Systems, assemblies, and methods are provided herein for fastening of one bone to another bone using one or more sutures. The features herein enable such fastening with a more accurate strength, and which can be more easily fastened in-situ.

An exemplary method, and corresponding instrumentation, of balancing the ligaments of a knee during flexion is disclosed. In one embodiment, the method includes forming initial resection cuts in a patient' femur and tibia, and subsequently placing the knee in flexion to form a flexion space between the posterior femoral condyles and the resected tibial surface. The method may further include sequentially inserting one or more flexion spacers into the flexion space, and selecting the flexion spacer that provides the ligaments with equal tension. The flexion spacers may include a medial platform and a lateral platform wherein, for at least one of the flexion spacers, the lateral platform has a greater thickness than the medial platform. The method may further include engaging an alignment sizing tool with the selected flexion spacer, forming a pair of pin holes in the femur, and mounting a cutting block to the femur using the pin holes.

Various surgical cutting blocks are presented herein. One surgical cutting block includes a cutting platform including a positioning aperture formed on the cutting platform in which the positioning platform divides the cutting platform into first and second sides and the first side and/or the second side includes multiple single cut guides formed thereon. Another surgical cutting block includes a cutting platform including a positioning aperture formed on the cutting platform in which the positioning platform divides the cutting platform into first and second sides and the first side and/or the second side incudes a double cut guide formed thereon. Yet another surgical cutting block includes a cutting platform including a positioning aperture formed on the cutting platform in which the positioning platform divides the cutting platform into first and second sides and the first side and/or the second side includes a multi-cut guide formed thereon.
