A placeholder for vertebrae or vertebral discs includes a tubular body, which along its jacket surface has a plurality of breakthroughs or openings for over-growth with adjacent tissue. The placeholder includes at least a second tubular body provided with a plurality of breakthroughs and openings at least partially inside the first tubular body. The first and second tubular bodies can have different cross-sectional shapes, can be are arranged inside one another by press fit or force fit or can be connected to each other via connecting pins and arranged side by side to one another in the first body.

An instrument for holding and inserting a bone anchor into a bone is provided, where the bone anchor includes a shank for anchoring in the bone and a head. The instrument includes a holding member for holding the head of the bone anchor and has a plurality of arms configured to at least partially encompass the head, where the arms include an inner surface forming a seat for the head. The instrument also includes a drive shaft for engaging the head of the bone anchor and defining a longitudinal axis of the instrument. The instrument further includes a displacement member configured to act on the holding member. The holding member can assume a first configuration in which it is configured to permit the head to enter the seat and a second configuration in which it is configured to hold the head in the seat.

The present invention generally relates to bone implants. More specifically, the present invention relates to bone implants used for the fixation and or fusion of the sacroiliac joint and/or the spine. For example, a system for fusing and or stabilizing a plurality of bones is provided. The system includes an implant structure having a shank portion, a body portion and a head portion. The body portion is coupled to the shank portion and is configured to be placed through a first bone segment, across a bone joint or fracture and into a second bone segment. The body portion is configured to allow for bony on-growth, ingrowth and through-growth. The head portion is coupled to the proximal end of the shank portion and is configured to couple the shank portion to a stabilizing rod. Methods of use are also disclosed.

Methods and systems for monitoring a rod reduction process is provided. The methods and systems include determining, based on at least one parameter, a threshold for forces exerted by a tool on a rod or a pedicle screw and receiving data corresponding to a magnitude of the forces exerted by the tool on the pedicle screw or the rod during reduction of the rod into a head of the pedicle screw. A surgical plan may be updated when the monitored magnitude meets the threshold.

A locking-cap module may include a locking-cap having a first connecting flange and a second connecting flange opposite the first connecting flange extending from a side surface of the locking-cap. The locking-cap may further include a first retaining rail and a second retaining rail opposite the first retaining rail. The locking-cap module may further include a set screw configured to engage with corresponding threads of the locking-cap. In some embodiments, the first connecting flange and second connecting flange are configured to engage with a connector such that the top surface of the locking-cap is flush with a top surface of the connector in an engaged position. In some embodiments, the set screw is initially coupled to the locking-cap by a pre-loaded connection. In some embodiments, a surgical tool is provided for rotating the locking-cap module into the engaged position.

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.

An implant bending device includes a first work surface. An implant support is movable relative to the first work surface. A second work surface is movable relative to the first work surface. A sensor is connected with the work surfaces and configured to detect contact of at least one of the work surfaces with an implant. Systems, surgical instruments, spinal constructs, implants and methods are disclosed.

A bone screw has a first portion including a head. A second portion includes a threaded shaft having a length and a major diameter. The shaft includes a length-to-major diameter ratio of less than about 2.0. The thread has a minor diameter and includes a major-diameter-to-minor diameter ratio of greater than about 2.0. The shaft further has at least one thread including a pitch of greater than about 1.0 mm and defining a pitch cavity for disposal of tissue. Systems and methods of use are disclosed.

Systems and methods include solutions for fixation at the rib head for fractures and osteotomies adjacent to the rib head and transverse process. The disclosed rib plates, anchor systems, other implants, and instrumentation may also be applied to mid-rib fractures. The systems and methods may be used in the treatment of rib deformities, including the correction of rib hump deformity via thoracoplasty, as well as general corrections of chest and rib deformities. Systems and methods herein may be used in chest wall reconstructions due to trauma, cancer, or deformity.

An anchoring system for implanting in bone, the system comprising a first coupling assembly having a first clamp and a first coupling body that receives and holds a first stabilization element; a second coupling assembly that receives and holds a second stabilization element; and a plate that attaches to the first coupling assembly and the second coupling assembly, wherein the first coupling assembly attaches to a bone fastener, and wherein the first coupling body includes a cap retainer that receives a locking cap that applies a directional force to force the first coupling body toward the plate, and applies another directional force to force the first clamp toward the plate, thereby fixedly securing the first coupling body and the first clamp to the plate.
