An expandable device comprising, a body defining a bore, a shaft received in the bore of the body, an end plate coupled to the shaft, wherein rotation of the shaft translates the end plate with respect to the body, and a locking mechanism engaged with the shaft so as to permit the shaft to rotate in a first direction and apply a resistance force to resist the shaft when attempting to rotate in a second direction.

Expandable implant with worm gear

A spinal fixation device includes an outer housing and an end plate assembly coupled with the outer housing. The outer housing defines an aperture and a longitudinal axis. At least a portion of the end plate assembly is slidably received within the outer housing. The end plate assembly includes a first end plate configured to engage a vertebral body, wherein the end plate assembly is selectively movable between a first position in which the first end plate is spaced apart from the outer housing and a second position in which the first end plate is adjacent the outer housing. Further, the first end plate is selectively adjustable to an angular orientation of a plurality of angular orientations with respect to the longitudinal axis of the outer housing.

Spinal fixation device

A driving instrument for adjusting a spinal implant includes an outer shaft having a distal end configured to actuate a proximal adjustment assembly of a spinal implant, and an inner shaft having a distal end configured to actuate a distal adjustment assembly of the spinal implant. The inner shaft is disposed within the outer shaft, with a proximal end of the inner shaft extending proximally from the outer shaft. The proximal end is configured to be rotated such that rotation of the inner shaft results in simultaneous rotation of the inner and outer shafts, with rotation of the outer shaft ceasing at a first value of resistance associated with the proximal adjustment assembly and rotation of the inner shaft ceasing at a second value of resistance associated with the distal adjustment assembly such that cessation of rotation of the inner shaft is independent from cessation of rotation of the outer shaft.

Devices for inserting and expanding spinal implants

According to one embodiment of the disclosure, an implant includes a body having a surface with a flexible pattern defined by a plurality of material segments including a first material segment and a second material segment. The first material segment abuts the second material segment. Further, the first material segment includes a first non-linear shape extending between a first end and a second end while the second material segment includes a second non-linear shape extending between a first end and a second end. The two material segments are interconnected such that one of the first end and the second end of the first non-linear shape is interconnected with one of the first end and the second end of the second non-linear shape.

Implants and instruments with flexible features

An interbody spacer is provided including a body portion defining a longitudinal axis. The body portion includes a distal end portion, a proximal end portion, opposed side surfaces that extend between the distal and proximal end portions, and top and bottom surfaces configured and adapted to engage vertebral bodies. The interbody spacer includes first orifices defined through the top surface. The first orifices include orifices having first and second cross-sectional configurations and the first orifices are arranged in rows extending along the longitudinal axis.

Interbody spacer

A spinal fixation device includes a housing defining a chamber and a longitudinal axis, and an end plate assembly operatively coupled with the housing. The end plate assembly includes a first end plate configured to engage a vertebral body and first and second support assemblies operatively coupled to the first end plate. The first support assembly is selectively movable between a first position in which the first end plate is spaced apart from the housing and a second position in which the first end plate is adjacent the housing. The second support assembly is transitionable between a first state in which the first end plate has a first angular orientation and a second state in which the first end plate has a second angular orientation.

Corpectomy device and methods of use thereof

An interbody at least one surface including a plurality of members that are independently configured and dimensioned to move from a first position to a second position is disclosed.

Interbody with extendible members

A bone screw for attaching a spinal prosthetic or bone plate to bone includes a tubular body having open proximal and distal ends. The open proximal and distal ends define a passageway therethrough. A shaft is insertable into the passageway and includes a distal tip that extends beyond the open distal end. The shaft is insertable through a lumen of a head of the bone screw. A gap is defined between a distal surface of the head and a proximal end of the tubular body. The shaft is rotationally fixed with the tubular body and the head. The head is repositionable with respect to the shaft such that an acute angle is defined between the head and a longitudinal axis of the shaft.

Semi-constrained bone screw and insertion instrument

A spinal implant configured for positioning within a space between adjacent vertebral bodies includes first and second bone screws and a body. The body includes a back surface having first and second openings for receiving the first and second screws. The first and second openings are configured for orientation towards opposing vertebral bodies. The body further includes first and second side surfaces extending from opposing ends of the back surface and first and second end surfaces extending from respective first and second side surfaces, wherein the ends of the first and second end surfaces meet and define an atraumatic nose. A first angle is formed between the first side surface and the first end surface that is different than a second angle that is formed between the second side surface and the first end surface. A method using same is also disclosed.

Spinal implant

A spinal plate that is self-adjusting along its longitudinal axis to accommodate subsidence that may occur and aid in loading the bone graft to promote boney fusion while providing rigid fixation. The spinal plate is configured to inhibit loosening or backing out of bone screws.
