An expandable interbody spacer for the spine is provided. The interbody spacer includes a housing, upper and lower endplates, an anterior actuator, a posterior actuator, an anterior drive screw, and a posterior drive screw. The anterior and posterior drive screws are independently or simultaneously rotated with respect to each other by a driver to wedge one or more of the anterior and posterior actuators between the endplates moving them into parallel and / or angular expansion.

An interbody spacer for the spine is provided. The interbody spacer includes a cage and at least one bone screw configured to anchor the cage between two vertebrae of the spine. The cage includes a lock rotationally movable with respect to the cage between a locked configuration and an unlocked configuration. When in an unlocked configuration, bone screws may be inserted and removed from the cage. When in a locked configuration, the insertion and removal pathway of the bone screw is blocked by the lock, thereby, providing backout protection for the bone screws. The lock is coupled to the cage by a pronged retainer and includes a camming surface to provide for incremental rotation of the lock. The lock includes a space-saving shape providing for maximum bone screw angulation on a laterally smaller anterior platform.

The invention discloses a computed tomography spinal fracture auxiliary diagnosis system. The system comprises the following steps: step 1, collecting CT images, marking the CT images, and arranging the CT images into a data set; step 2, constructing a deep learning neural network based on multi-segment consistency constraint, wherein the deep learning neural network comprises positioning and marking of a spine centrum and diagnosis of a spine fracture level; step 3, pre-training the backbone network; step 4, training and testing the neural network; and step 5, inputting a CT image to be diagnosed into the trained network, and outputting a diagnosis result. The method has the advantages that: the spine image information is subjected to feature extraction through the two-stage network, a subsequent consistency analysis module is helped to pay attention to the spine centrum information, and a consistency comparison module is introduced, so that the model learning difficulty is remarkably reduced, the model performance is improved, and the diagnosis accuracy is improved.

The invention discloses an anterior cervical subtotal subcorpectomy physiological internal fixation, which comprises two retaining brackets on the two ends and a plurality of intermittent fixation units. Each intermittent fixation unit comprises one adjustable mechanism, the two ends of adjustable mechanism are connected with one knuckle arm respectively, the outer part of adjustable device is equipped with one lantern ring, the lantern ring is connected with two anterior pedicle of vertebral arch screws, the end of rear pedicle of vertebral arch screws, the end of knuckle arm is equipped with bulb or ball socket, the two near intermittent units are connected with each other through bulb and ball socket to form movable fit, the intermittent fixation unit is also connected with retaining bracket through bulb and ball socket to form movable fit. The fixation device is suitable for fiaxtoin for a plurality of continuous subtotal subcorpectomys, and maintains the up and down motion between near vertebra, reduces compensation motion for near vertebra and prevents vertebra degeneration.

The invention relates to an intervertebral spacer for spinal surgery. The intervertebral spacer has one or more surfaces with a unique surface pattern. The interbody spacer is preferably designed for use in spinal fusion procedures in which the portion of the affected disc is removed from between two adjacent vertebrae and replaced with an interbody spacer that provides segment stability, which can correct deformity and allow bone to grow between the two vertebrae, and gaps caused by intervertebral disc resection are bridged. The intervertebral spacer has one or more unique surfaces intended to facilitate bone growth and attachment. The unique surface includes one or more surface protrusions, generally referred to as a pattern or matrix of surface protrusions, which may be arranged to form unique patterns and structures.
