The present subject disclosure provides a novel design for devices and methods for straightening a curved spine by using a reduction tool to move the spine with respect to an attached bone plate.

Reduction instruments and methods

A spinal fixation construct for aligning vertebral bodies includes a bone screw, a spinal rod, a flexible member, and a fixation member. The spinal rod is disposed within a saddle portion of a housing of the bone screw, and includes an elongated body having a first end and a second end. The spinal rod is formed from a first material having a first modulus of elasticity. The flexible member is coupled to the spinal rod, and includes an elongated body having a first end portion and a second end portion. The flexible member is formed from a second material having a second modulus of elasticity that is different from the first modulus of elasticity. The fixation member includes a threaded body portion and a head portion defining a hole therethrough. A portion of the flexible member extends through the hole of the head portion.

Spinal fixation construct and methods of use

A transverse connector includes a cross member connecting assembly, and first and second spinal rod connection members rotatably coupled to opposing end portions of the cross member connecting assembly. The cross member connecting assembly includes a first band slot defined therethrough and a threaded opening extending through an upper surface of the cross member connecting assembly and into the first band slot. The cross member connecting assembly includes a band set screw threadingly engaged with the threaded opening and movable relative to the first band slot.

Transverse connector

A system for securing a flexible member to a vertebra includes a flexible member, a fixation member, and an inserter. The flexible member includes two ends. The fixation member includes a head and a shank that defines a longitudinal axis of the fixation member. The head defines a slot that passes through the head orthogonal to the longitudinal axis. The slot receives a portion of the flexible member. The inserter includes a handle and a tubular member that has proximal and distal end portion. The proximal end portion is attached to the handle and the distal end portion extends from the handle. The tubular member defines a passage between the proximal and distal end portions. The distal end portion includes a couple for receiving the head of the fixation member with the portion of the flexible member received in the slot of the flexible member.

Spinal construct with flexible member

A growing spinal rod system is configured to grow in response to the growth of a patient. The growing spinal rod system includes a housing, a spacer, and a sliding spinal rod. The housing includes a stepped passage therethrough. The spacer is disposed within the stepped passage and defines a through hole. The spacer includes a plurality of ribs biased inwards and into the through hole. The sliding spinal rod is slidably inserted through the through hole of the spacer. The sliding spinal rod moves the plurality of ribs outwards. The plurality of ribs permits the sliding spinal rod to extend from the housing and inhibit the sliding spinal rod from retracting into the housing.

Growing spinal rod system

An axial spinal rod connector includes a central connector and first and second portions. The first and second portions are each integrally formed with the central connector to define a longitudinal axis. Each of the first and second portions includes an outer end portion and a set screw. The outer end portion defines a passage about the longitudinal axis and defines a blind hole orthogonal to the longitudinal axis. The blind hole extends into the passage. The passage is sized and configured to slidably receive a spinal rod. The set screw is sized and configured to engage the blind hole. The set screw at lease partially interfering with the passage when engaged with the blind hole to fix a spinal rod relative to the spinal rod connector.
