Abstract
Apparatuses for distal fibula replacement and related methods are described herein. The apparatus generally includes an implantable stem component including a proximal portion that is contoured to have an anterior overlap with a portion of a fibula bone of a patient, and a distal portion that defines a first channel configured to receive a peronaeus brevis tendon and a further defines second channel configured to receive a peronaeus longus tendon. Related methods include placing such an apparatus on the portion of the fibula bone of the patient.
Claims17
An apparatus for distal fibula replacement in a patient, the apparatus comprising:
- an implantable stem component comprising a proximal portion and a distal portion;
- wherein the proximal portion is contoured to form an anterior overlap for engaging with a portion of a fibula bone;
- wherein the distal portion defines a first channel positioned and contoured to operatively receive a peronaeus brevis tendon, and the distal portion further defines a second channel positioned and contoured to operatively receive a peronaeus longus tendon;
- wherein the first channel has an angle from superior posterior to distal anterior in the range of about 35 degrees to about 55 degrees, and the second channel has an angle from superior posterior to distal anterior in the range of about 25 degrees to about 45 degrees;
- and
- wherein the proximal portion defines one or more holes, each of the one or more holes configured to direct a respective connector when extending therethrough so as to affix the proximal portion to the portion of the fibula bone when installed on the patient, and wherein the apparatus further defines one or more apertures, each aperture configured to direct a respective connector when extending therethrough so as to affix the apparatus to a syndesmosis when the apparatus is installed on the patient.
A method comprising
- placing an apparatus for distal fibula replacement so that a proximal portion of the apparatus has anterior overlap with a portion of a fibula bone of a patient;
- and
- placing one or more screws through apparatus so as to affix the apparatus to the portion of the fibula bone;
- wherein the apparatus comprises the proximal portion contoured to form the anterior overlap with the portion of the fibula bone, and a distal portion that forms a first channel positioned and contoured to operatively receive a peronaeus brevis tendon, and the distal portion further forms a second channel positioned and contoured to operatively receive a peronaeus longus tendon;
- wherein the first channel has an angle from superior posterior to distal anterior in the range of about 35 degrees to about 55 degrees, and the second channel has an angle from superior posterior to distal anterior in the range of about 25 degrees to about 45 degrees;
- and
- wherein the proximal portion defines one or more holes, each hole configured to direct a respective connector when extending therethrough so as to affix the apparatus to the portion of the fibula bone when installed on the patient, and wherein the apparatus further defines one or more apertures, each aperture configured to direct a respective connector when extending therethrough so as to affix the apparatus to a syndesmosis when installed on the patient.
