摘要:
Provided is a system and method for providing a non-binding allograft subtalar joint implant for surgical implant into a person's foot proximate to the ankle. This system for repair includes at least one sterile non-binding allograft subtablar joint implant provided as a pre-formed allograft rod plug “ARP” having a diameter about equal to an average width of a canal between a person's talus and calcaneus bones, the ARP being resiliently compressible and flexible. When snuggly disposed between the person's talus and calcaneus bones, the ARP compresses during normal use of the person's foot and maintains the canal in an anatomically correct alignment and reduces a tendency for abnormal motion between the person's talus and calcaneus bones. An associated method of use is also provided.

摘要:
A distraction kit including at least one trial insert, at least one handle for coupling to the at least one trial insert, a correction indication guide, and at least one implant. A method for performing a distraction arthrodesis including inserting at least one trial insert into a joint and selecting a trial insert of the at least one trial insert for correction of the joint in a first plane. The method also including rotating the selected trial insert in a medial-lateral direction for correction of the joint in a second plane and selecting the needed correction in the first plane and the second plane. The method further including marking at least one bone for the selected correction. Then, marking the implant with the correction indication guide to achieve proper placement of the implant and joint correction replication from the desired trial positioning. Implants, devices, and systems are also disclosed.

One embodiment of the invention includes a sinus tarsi implant with a proximal portion that includes a spherical portion. The spherical portion may include apertures for tissue in-growth. The implant design limits patient discomfort due to pressure points. Other embodiments are disclosed.
摘要:
A system includes a cutting guide and a cutting template. The cutting guide has a body including a plurality of sides that together define a cavity that is accessible via an opening defined by a first side of the plurality of sides. A second side of the plurality of sides defines at least two elongate slots. The second side is disposed adjacent to the first side and at a distance from an opposed third side. Each of the at least two slots is in communication with the cavity and disposed at a different location along the second side. The cutting template has a body defining at least one elongate slot. The cutting template is configured to be engaged with the cutting guide such that the at least one elongate slot of the cutting template aligns with at least one of the at least two elongate slots of the cutting guide.
摘要:
A system for preparing a bone implant includes a cutting guide having a body including a plurality of sides that together define a cavity that is accessible via an opening defined by a first side of the plurality of sides. A second side of the plurality of sides defines a plurality of slots and is disposed adjacent to the first side. Each of the plurality of slots is in communication with the cavity that is sized and configured to receive a bone implant therein, and each of the plurality of slots is located at a different location of the second wall to facilitate cutting a bone implant into one of a plurality of sizes.
摘要:
Apparatus for fusing a first bone of a joint with a second bone of a joint, the apparatus comprising: a fusion block comprising a hollow tubular structure characterized by a first end, a second end and a lumen extending from said first end to said second end, the first end being configured to engage the first bone of the joint and the second end being configured to engage the second bone of the joint, the lumen being configured to span the distance from the first bone of the joint to the second bone of the joint and to receive and retain bone graft material therein, whereby to facilitate bone fusion across the fusion block; and at least one fusion plate for connecting the fusion block to the first bone of the joint and the second bone of the joint.
摘要:
Methods and devices are disclosed for manipulating alignment of the foot to treat patients with flat feet, posterior tibial tendon dysfunction and metatarsophalangeal joint dysfunction. An inflatable implant is positioned in or about the sinus tarsi and/or first metatarsal-phalangeal joint of the foot. The implant is insertable by minimally invasive means and inflatable through a catheter or needle. Inflation of the implant alters the range of motion in the subtalar or first metatarsal-phalangeal joint and changes the alignment of the foot.
摘要:
A surgical device for treating the pathology of flat feet, the device comprising an outer casing; and an expansion member suitable for moving inside said outer casing in a compression direction, for causing said outer casing to expand radially; the surgical device being provided with non-return check means shaped to allow the expansion member to move in the compression direction towards an operating position inside the outer casing and to oppose movement of the expansion member in the reverse direction once said operating position is reached, so as to prevent the expansion member from being expelled.
