Abstract
Disclosed herein are various embodiments of a modular digit fixation system that has two or more attachable and adjustable modules. The modules are attachable to separate adjacent digits and each other and have multiplanar adjustability. Two modules are disclosed: an elongate module and a cylindrical module having a body and a slidable clamp. Further, the embodiments also include various related components, devices, methods, and technologies.
Claims18
A modular digit fixation system, comprising:
- (a) at least one first digit fixation module comprising:
- (i) a modular body comprising:
- (A) a flange;
- (B) a first cylinder comprising a first lumen sized to receive a first intramedullary fixation rod implantable in a first digit bone of a patient;
- and
- (C) a first coupling mechanism configured to selectively lock the first cylinder at a desired position along the first intramedullary fixation rod;
- and
- (ii) a clamp slidably coupled to the flange;
- and
- (b) a second digit fixation module comprising:
- (i) a second cylinder comprising a second lumen sized to receive a second intramedullary fixation rod implantable in a second digit bone of the patient;
- and
- (ii) a second coupling mechanism configured to selectively lock the second cylinder at a desired position along the second intramedullary fixation rod.
A modular digit fixation system, comprising:
- (a) at least two intramedullary fixation rods, wherein each of the at least two intramedullary rods is implantable into an elongate bone of a patient;
- (b) at least one first digit fixation module comprising:
- (i) a modular body comprising:
- (A) a flange;
- and
- (B) a first cylinder comprising a first lumen defined therein, wherein a first of the at least two intramedullary fixation rods is positionable within the first lumen;
- (ii) a clamp slidably coupled to the flange such that the clamp is slidable along a length of the flange, the clamp comprising:
- (A) a first clamp arm;
- (B) a second clamp arm;
- and
- (C) a clamp lumen defined by the first and second clamp arms;
- and
- (c) a second digit fixation module comprising a second cylinder comprising a second lumen defined therein, wherein a second of the at least two intramedullary fixation rods is positionable within the second lumen.
A method for fixation of at least two digits, the method comprising:
- implanting a first intramedullary fixation rod into a first digit bone;
- implanting a second intramedullary fixation rod into a second digit bone;
- positioning a first digit fixation module over the first intramedullary fixation rod, the first digit fixation module comprising:
- (a) a modular body comprising:
- (i) a flange;
- and
- (ii) a first cylinder comprising a first lumen defined therein;
- and
- (b) a clamp slidably coupled to the flange such that the clamp is slidable along a length of the flange, the clamp comprising:
- (i) a first clamp arm;
- (ii) a second clamp arm;
- and
- (iii) a clamp lumen defined by the first and second clamp arms,
- wherein the positioning of the first digit fixation module over the first intramedullary fixation comprises positioning the first intramedullary fixation rod in the first lumen;
- positioning a second digit fixation module over the second intramedullary fixation rod, the second digit fixation module comprising a second cylinder comprising a second lumen defined therein, wherein the positioning of the second digit fixation module over the second intramedullary fixation comprises positioning the second intramedullary fixation rod in the second lumen;
- and
- attaching the first digit fixation module to the second digit fixation module via the clamp.
