The disclosure relates to a vertebral body implant including a flexible main body and at least one pedicle screw joint. The flexible main body is an integrally formed single piece having at least one joint-accommodating hole and at least one opening connected to the at least one joint-accommodating hole. The pedicle screw joint is an integrally formed single piece movably accommodated in the at least one joint-accommodating hole.

Vertebral body implant

An implanting apparatus and an operating method thereof are provided. An implanting apparatus used for implanting an intervertebral cage into a location between two adjacent vertebral bodies, wherein the implanting apparatus comprises a sleeve and an extension member. The extension member has a rod and a coupling column, wherein the rod is screwed inside the sleeve, the coupling column is connected to one end of the rod and exposed outside the sleeve, and the axial direction of the coupling column is substantially perpendicular to that of the rod. When one end of the coupling column is disposed on an inner arc surface of a connecting portion of the intervertebral cage and the rod is rotated with respect to the sleeve, the distance between the coupling column and the sleeve is decreased so as to clamp the connecting portion of the intervertebral cage between the coupling column and the sleeve.

Implanting apparatus and operating method thereof

A spinal fixation assembly includes a pedicle rod and pedicle screws which secure the pedicle rod to the spine. Each pedicle screw includes a head configured to receive a portion of the pedicle rod, and a threaded portion extending from a first end of the head and configured to engage a vertebra. The pedicle rod is secured to the head by a fastener. The head includes a breakaway region that defines a location in which at least a first portion of the head can be easily separated from the remainder of the head upon application of sufficient force to the first portion. A minimally invasive method of implanting the spinal fixation assembly is disclosed.

Minimally invasive spinal stabilization method

An intervertebral cage, an implanting apparatus and an operating method thereof are provided. The intervertebral cage for being implanted between two adjacent vertebral bodies includes a body and a connecting portion. The body has a lateral convex surface, an inclined surface, a lateral concave surface and a connecting surface connected sequentially. The connecting portion includes a main portion and a protrusion. The main portion connected to the connecting surface has a through hole. The protrusion is protruded from the main portion into the through hole to form first and second inner arc surfaces. The maximum width of the intervertebral cage is a distance between first and second lines. The first and second lines are substantially parallel to a tangent line of the lateral convex surface and the first line, respectively. The distance between the inclined surface and the first line decreases gradually along a direction away from the connecting portion.

Intervertebral cage and implanting apparatus and operating method thereof

Minimally invasive spinal stabilization system

A method for filling a bone defect in a subject in need thereof is disclosed. The method includes heating a bone cement composition at a first temperature where the bone cement composition is fluidic, and delivering an effective amount of the fluidic bone cement composition at a second temperature to the bone defect thereby filling the bone defect and allowing the fluidic bone cement composition to solidify, the second temperature being sufficiently high for maintaining the bone cement composition fluidic without causing thermal necrosis. Also disclosed are systems for carrying out the method.
