Filed:

Jan 12, 2007

Appl. No.:

12/161244

Inventors:

Carl T. Hasselman - Oakmont PA, US

International Classification:

A61F 2/42

US Classification:

623 2118

Abstract:

A method prepares an ankle joint of a patient for replacement. The patient includes a tibia () having a medial portion (), a talus (), and an ankle () having a medial portion. The method employs a cutting alignment apparatus () including a first portion external to the patient and a second portion, and surgically prepares and exposes the medial portion of the ankle for replacement. The second portion of the cutting alignment apparatus is coupled to the tibia, and a cutting guide () is disposed with respect to the cutting alignment apparatus. The medial portion of the tibia is detached, a portion of the tibia proximate the talus is cut, and a portion of the talus proximate the tibia is cut. An ankle prosthesis () is installed to the ankle, and the medial portion of the tibia is reattached.

US Classification:

606151, 606228

Abstract:

A fastener () is provided for securing a soft tissue () to a bone () upon actuation of an actuating mechanism (). The fastener () includes an elongated tubular shaft () having first and second opposing ends (), an aperture () extending from the second end () toward the first end (), and a collar () disposed at or about the second end (). The first end () of the elongated tubular shaft () is inserted through the soft tissue (), through the exterior surface () of the cortex () and into the interior () of the bone (). The collar () engages and secures the soft tissue (). In response to being actuated by the actuating mechanism (), a portion () of the elongated tubular shaft () deforms against the cortex () within the bone (), thereby securing the soft tissue () between the collar () and the exterior surface () of the cortex () of the bone (). A tissue fastener system () and an associated method of fastening soft tissue () to a bone () are also disclosed.

Inventors:

Carl T. Hasselman - Oakmont PA, US

Assignee:

SYNTHES USA, LLC - West Chester PA

International Classification:

A61B 17/56

US Classification:

606 87

Abstract:

An osteotomy guide is provided for cutting a bone, such as the medial distal tibia, to facilitate an ankle replacement. The osteotomy guide includes a positioning device having a number of fixation points, a first guide member structured to align with a first portion of the bone, in order to perform a first procedure, thereon, and a second guide member structured to align with a second portion of the bone, in order to perform a second procedure thereon. The fixation points engage the bone and maintain alignment of the first guide member with respect to the first portion during the first procedure, and maintain alignment of the second guide member with respect to the second portion during the second procedure, in order that the first procedure and the second procedure are substantially reproducible.

International Classification:

A61B 17/80
A61B 17/17

Abstract:

Internal beam plates and associated instrumentation may be utilized for performing arthrodesis procedures, bone fracture procedures, osteotomy procedures, etc. Exemplary surgical methods that may be performed using the internal beam plates and associated instrumentation include, but are not limited to, lapidus bunionectomy procedures, metatarsophalangeal (MTP) procedures, chevron procedures, fracture repair procedures, etc. The exemplary internal beam plates incorporate an integral beam that is configured to increase strength and stiffness across a fusion site. The exemplary cutting/prep guides are configured to allow surgeons to reduce, prepare, and cut bones for receiving the beam of the internal beam plate using one or more guides.
