Method, system, and apparatus for mammalian bony segment stabilization
View Patent ↗Embodiments of bony region stabilization are described generally herein. Other embodiments may be described and claimed.
1. A method for stabilizing a bony region, comprising:
fixably coupling an elongated element to the bony region with a bony fixation element, the elongate element having a long axis, a front and a back, the elongate element including:
a first opening configured to receive a bony fixation element and extending from the elongate element front to the elongate element back; and
a cavity within the elongated element; and
securely inserting a bony fixation element retention module within the elongated element cavity, the retention module including a first arm, the first arm deflectably extending into the first opening and wherein the retention module first arm limits the protrusion of a bony fixation element in the first opening beyond the elongated element front, the elongate element further having a first channel or slot communicating between the first opening and the cavity, the retention module first arm deflectably extending from the cavity into the first opening via the first channel, each first channel or slot formed under one or more tabs, each first arm having shoulders that engage the tabs limiting the movement to prevent expulsion of the retention module during first arm deformation.
2. The method of claim 1 , the elongated element further comprising a second opening configured to receive another bony fixation element and extending from the elongate element front to the elongate element back.
3. The method of claim 2 , further comprising:
fixably coupling the elongated element to the bony region with another bony fixation element; and
the retention module further including a second arm, the second arm deflectably extending into the second opening, wherein the retention module second arm limits the protrusion of the other bony fixation element in the second opening beyond the elongated element front, the elongate element further having a second channel or slot communicating between the second opening and the cavity, each second channel or slot formed under one or more tabs, each second arm having shoulders that engage the tabs limiting the movement to prevent expulsion of the retention module during second arm deformation.
4. The method of claim 3 , the retention module second arm deflectably extending from the cavity into the second opening via the second channel.
5. The method of claim 4 , wherein the bony region includes a vertebral body.
6. The method of claim 1 , deflecting the retention module first arm toward the cavity to enable removal of a bony fixation element from the first opening beyond the elongated element front.
7. The method of claim 3 , deflecting the retention module second arm toward the cavity to enable removal of a bony fixation element from the second opening beyond the elongated element front.
