Abstract: An apparatus and method for performing endoscopic carpal tunnel release (ECTR) surgery, thereby decreasing the pressure within the carpal tunnel that impairs median nerve function.

Abstract: An apparatus and method for identifying the flexor retinaculum of the carpal tunnel, injecting an effective amount of an agent into at least a portion of flexor retinaculum or tissue adjacent thereto, wherein the agent is configured to weaken the flexor retinaculum. The system may further include means for increasing the tensile stress in the flexor retinaculum post-injection using hand exercises, thereby weakening its structural integrity and decreasing the pressure within the carpal tunnel that impairs median nerve function.

Abstract: An apparatus for treating a fracture of the distal radius of a patient, having a pivot pin configured to engage the radius at an attachment point distal to the fracture, and a handle assembly configured to engage the pivot pin dorsal to the patient's hand is presented. The pivot pin is configured to insert through and fixedly engage at least a portion of the distal fracture bone fragment associated with the radius. The handle assembly, once coupled to the pivot pin, provides adjustment of the position of the distal fracture bone fragment.

Abstract: Systems, device and methods are described for maintaining concentric reduction of the proximal interphalangeal (PIP) joint of a finger with few as two orthopedic pins, one inserted through the head of the proximal phalanx concentric with the axis of rotation of the joint (i.e., a transverse pin), and the other through the middle phalanx at a location between the PIP and distal interphalangeal (DIP) joint (a dorsal pin), and applying a force between the two pins. A surgical kit is described which may include such components as a dorsal pin, a transverse pin, a pin placement guide for use in reducing the joint fracture dislocation and then drilling holes for the pins or for inserting self-drilling pins, and a fixation device for coupling and applying a force between the dorsal and transverse pins. The components of the surgical kit are described, including various configurations of the fixation device.

Abstract: A finger suffering from contracture of the proximal interphalangeal (PIP) joint is treated by application of a device that includes two pivotally joined sections, one of which is securable to the middle phalanx of the finger and the other to another portion of the patient's finger, hand or wrist, with an element that applies torque to the sections. The pivot axis of the two sections is dorsal to the finger, and the torque-producing element and the pivot axis define a moment arm whose length varies in inverse relation to the tension applied to the tensioning element. Torque is applied to the PIP joint without a functionally significant torque being applied to the metacarpal phalangeal (MP) joint, and the device requires attachment only to the dorsal aspect of the phalanx that is distal to the joint being treated rather than to both the distal phalanx and the proximal phalanx.

Abstract: A joint of a human upper extremity is biased by an apparatus that includes a U-shaped frame, a distal attachment portion mounted to the frame through a biasing member and attachable to the extremity at a location distal to the joint, and a wrist brace or proximal attachment portion that attaches to the extremity at a location proximal to the joint, the frame being rotatable relative to both the distal attachment portion and the wrist brace. Up to four distal attachment portions can be attached to the same U-shaped frame to bias joints on each of four distinct extremities, such as four fingers on the same hand.

Abstract: A wrist brace provides a mounting point, a means to hold the hand in position relative to the apparatus, and spreads the force evenly over a large area. Positioned over the dorsal surface of the brace is a "U" shaped transverse member that is attached to the wrist brace through two swivel joints on the ulnar and radial sides of the brace. The pivot means are positioned such that a straight line drawn between them generally passes through the axes of rotation of the metacarpal phalangeal (MP) joints. Positioned dorsally above the proximal interphalangeal (PIP) joint are two members, one of which has an arc shaped tail for its dorsal surface. The other is a slider block which engages and slides around this first arc member. The arc member is mounted to the middle phalanx of the subject finger in such a way that the projected center of the arc would be coincident with the axis of rotation of the PIP Joint.
