Abstract
Embodiments are generally directed to an apparatus for reducing a rod into an orthopedic fixation device. An embodiment provides a rod-reducing apparatus. The rod-reducing apparatus may comprise a housing comprising a threaded through bore. The rod-reducing apparatus further may comprise a reduction shaft comprising a shaft portion and a through bore in the shaft portion, wherein the shaft portion may be configured to be received within the threaded through bore of the housing. The locking cap driver may comprise a locking cap driver comprising a shaft portion that may be configured to be received within the through bore of the reduction shaft, wherein a distal end of the shaft portion may be configured for attachment to a locking cap assembly.
Claims17
A method for rod reduction comprising:
- securing an orthopedic fixation device into bone;
- providing a rod-reducing apparatus, the rod-reducing apparatus including:
- a housing comprising a threaded through bore, wherein the housing includes an extension configured to couple the rod-reducing apparatus to tabs of a reducing head,
- a reduction shaft comprising a shaft portion and a through bore in the shaft portion, wherein the shaft portion is configured to be received within the threaded through bore of the housing,
- a locking cap driver comprising a shaft portion that is configured to be received within the through bore of the reduction shaft, wherein a distal end of the shaft portion is configured for attachment to a locking cap assembly,
- coupling the rod-reducing apparatus to the tabs of the reducing head, the tabs extending from the orthopedic fixation device, wherein the tabs define a channel therebetween for receiving the extension;
- and
- driving the reduction shaft through the housing to reduce a rod into the orthopedic fixation device.
A method for rod reduction comprising:
- securing an orthopedic fixation device into bone;
- providing a rod reduction system including:
- a reducing head comprising tabs, wherein a channel is defined between the tabs;
- a driving apparatus comprising a shaft portion;
- a rod-reducing apparatus, wherein the rod-reducing apparatus includes:
- a housing comprising a threaded through bore, wherein the housing is configured for attachment to the tabs of the reducing head, wherein the housing includes an extension configured to couple the rod-reducing apparatus to the reducing head, wherein the extension is configured to be received within the channel of the reducing head;
- a reduction shaft comprising a shaft portion, a connector portion at a proximal end of the shaft portion, and a through bore in the shaft portion, wherein the shaft portion is configured to be received within the threaded through bore of the housing, wherein the connector portion is configured for engagement with the driving apparatus;
- and
- a locking cap driver comprising a shaft portion that is configured to be received within the through bore of the reduction shaft, wherein a distal end of the shaft portion is configured for engagement with a locking cap assembly, and wherein a proximal end of the shaft portion is configured for engagement with the driving apparatus;
- coupling the rod-reducing apparatus to the tabs of the reducing head, the tabs extending from the orthopedic fixation device;
- and
- driving the reduction shaft through the housing to reduce a rod into the orthopedic fixation device.
