Abstract

Intervertebral implants and methods of delivering the intervertebral implants include delivering an implant through the Kambin's triangle from a posterolateral approach. The intervertebral implants can include a first body portion having an open configuration and a closed configuration. The intervertebral implants can also include a second body portion having an open configuration and a closed configuration. The first body portion removably connects to the second body portion.

Description

BACKGROUND[0001]1. Field[0002]The present application relates to medical devices and, more particularly, to a medical device and method for treating the spine.[0003]2. Description of the Related Art[0004]The human spine is a flexible weight bearing column formed from a plurality of bones called vertebrae. There are thirty-three vertebrae, which can be grouped into one of five regions (cervical, thoracic, lumbar, sacral, and coccygeal). Moving down the spine, there are generally seven cervical vertebrae, twelve thoracic vertebrae, five lumbar vertebrae, five sacral vertebrae, and four coccygeal vertebrae. The vertebrae of the cervical, thoracic, and lumbar regions of the spine are typically separate throughout the life of an individual. In contrast, the vertebra of the sacral and coccygeal regions in an adult are fused to form two bones, the five sacral vertebrae which form the sacrum and the four coccygeal vertebrae which form the coccyx.[0005]In general, each vertebra contains an a...

AI Technical Summary

Benefits of technology

This patent describes an intervertebral implant that can be used in orthopedic surgery. The implant has two parts that can pivot around a shaft, allowing for flexibility in movement. The parts can be connected or disconnected, and they form a ball and socket joint. The implant can also have textured surfaces, apertures, and bioactive coatings to anchor it into bone and resist movement. The method of surgery involves delivering the implant to the intervertebral space and transitioning it from a closed to an open configuration. The technical effect of this invention is to provide a flexible and secure intervertebral implant that allows for limited movement and engagement with the surrounding bone.

Problems solved by technology

Additionally, the vertebrae and associated connective elements are subject to injuries, including fractures and torn ligaments and surgical manipulations, including laminectomies.

Notwithstanding the variety of efforts in the prior art described above, these intervertebral implants and techniques are associated with another disadvantage.

In particular, these techniques typically involve an open surgical procedure, which results in higher cost, lengthy in-patient hospital stays and the pain associated with open procedures.

This results in additional movement of the patient.
