  • Patent number: 9730706
    Abstract: A method of using an orthopedic surgical instrument assembly that includes an instrument handle configured to clamp a broach and femoral stem trial assembly. A depth stop is configured to removably couple to the instrument handle. When the broach and femoral stem trial are advanced into a medullary canal of a patient's femur, a substantially planar proximal surface of the depth stop is configured to engage the distal surface of the femur, determining the depth of the broach in the medullary canal. The proximal surface of the depth stop is parallel to the joint line, defining an oblique angle to the anatomical axis of the femur. The depth stop may be attached to the instrument handle at a number of positions to control the depth of the broach. The assembly may include a spacer plate removably coupled to the depth stop that distalizes the broach in the medullary canal.

  • Publication number: 20140171951
    Abstract: In some examples, an apparatus includes a working surface including at least one material removal member. The material removal member is configured to remove at least some of a first portion of a first material. A protrusion extends outwardly from the working surface. The protrusion extends beyond the at least one material removal member by a first distance. The protrusion is configured to inhibit the at least one material removal member from removing at least a second portion of the first material. The second portion has a thickness substantially equal to the first distance.

  • Publication number: 20140163562
    Abstract: Methods and devices are described for modifying tissue in a spine of a patient to treat or alleviate spinal stenosis. In one embodiment, a method may include: advancing at least a distal portion of an elongate tissue modification device into an epidural space and between target tissue and non-target tissue in the spine; positioning the tissue modification device so that at least one abrasive surface of the device faces target tissue and at least one non-abrasive surface faces non-target tissue; applying tensioning force at or near separate distal and proximal portions of the tissue modification device; and translating the tissue modification device back and forth while maintaining at least some tensioning force to abrade at least a portion of the target tissue with the at least one abrasive surface. Unwanted damage to the non-target tissue may be prevented via the at least one non-abrasive surface.

  • Publication number: 20140114318
    Abstract: A method for preparing a first bone for receiving a prosthesis. The method includes coupling a revision alignment member to a template; positioning an offset alignment bushing relative to the revision alignment member; positioning the offset alignment bushing at the first bone such that an intramedullary member seated in the first bone extends through a passage defined by the offset alignment bushing; replacing the offset alignment bushing with a first bone cutting bushing; cutting the first bone using the first bone cutting bushing as a guide; replacing the first bone cutting bushing with an offset second bone cutting bushing; providing the second bone cutting bushing with a rotational orientation corresponding to a rotational orientation of the offset alignment bushing; and cutting the first bone using the offset second bone cutting bushing as a guide to prepare the bone to receive an offset prosthesis adapter.

  • Patent number: 8663228
    Abstract: Described herein are elongate devices for modifying tissue having a plurality of flexibly connected rungs or links, and methods of using them, including methods of using them to decompress stenotic spinal tissue. These devices may be included as part of a system for modifying tissue. In general, these devices include a plurality of blades positioned on (or formed from) rungs that are flexibly connected. The rungs are typically rigid, somewhat flat and wider than they are long (e.g., rectangular). The rungs may be arranged, ladder like, and may be connected by a flexible connector substrate or between two or more cables. Different sized rungs may be used. The blades (on the rungs) may be arranged in a staggered arrangement. A tissue-collection or tissue capture element may be used to collect the cut or modified tissue.
