The distal phalanges (foot) are located at the end of each toe. Three phalangeal bones make up each digit, articulating with each other at bending joints. The distal phalanges come at the end, right below the toenail. The distal phalanges articulate with the intermediate phalanges, which are joined to the proximal phalanges.
Articulating steerable clip applier for laparoscopic procedures
A long articulating steerable clip applier affixed to a user-operated handle. A surgical jaw assembly is attached to the other end of the clip applier. The clip applier is composed of articulating phalanges that are connected end to end by pivoting links and capable of angulations relative to one another when subjected to a tensile force. Each phalange has opposing s-shaped exterior grooves that form two continuous spiral-shaped channels for holding tension wires once the phalanges are assembled. Multiple tension wires are attached to opposite ends of adjacent phalanges. When each wire is pulled, this tensile force causes the phalanges to pivot at equivalent angles with each other. As each individual phalange pivots by an equivalent angle, the sum of these angles causes the free end of the clip applier to pivot by a large angle or a cascading actuation effect.

Methods and apparatus for repair of toe deformities using a bioabsorbable pin. The apparatus is a kit of part comprising a bioabsorbable pin, a predrill, a bone tamp, a cutter and a forceps. One surgical method of repairing toe deformities includes resecting a proximal interphalangeal joint, drilling a hole in a proximal phalanx using a proximal portion of a pin, removing the pin from the proximal phalanx, drilling a tip of a toe through middle and distal phalanxes, driving the pin retrograde and traversing the distal, middle and proximal phalanxes until the pin stops advancing due to resistance at a proximal cortex, holding the pin and powering a pin driver to separate a distal portion of the pin, and suturing the wound.

A glove formed of a flexible fabric, such as a natural or synthetic knit fabric, provides anterior and posterior portions having the outline of the phalanges and metacarpals of a human hand. A fourchette joins the anterior and posterior portions to one another. The fourchette has an arcuate shape prior to securement to the glove and thereby tends to curve the phalangeal portions of the glove. The fourchette extends to the lower edge of the cuff. Joints between the fourchette and the anterior and posterior portions maintain an opening formed by the cuff in an open position.

Fixing orthosis after restoration of extensor tendon rupture
InactiveCN101773423AReduced flexion angleAvoid the disadvantages of fixation in strong flexionMedical sciencePhysical medicine and rehabilitationProximal phalanx
The invention relates to a fixing orthosis after the restoration of extensor tendon rupture, which is characterized in that: the fixing orthosis after the restoration of extensor tendon rupture is made of thermoplastic mounded plastic, and is divided into five parts: a front arm part, a hand back part, a proximal phalanx part, a middle phalanx part, and a distal phalanx part. Each part is provided with a fixing band and a woolen hasp, and an angle-adjusting hinge axis is arranged between two parts. During use, after the angles among the parts are adjusted by adjusting the hinge axes, the fixing orthosis can be fixed on the affected limb through the fixing band and the woolen hasp which are arranged on each part. The fixing orthosis has the following advantages that: the fixing orthosis can selectively fix corresponding joints, only fixes the joints of injured fingers and avoids the stiffness of normal finger joints; and after the operation, flexion angles of the fingers are gradually reduced by adjusting the hinge axes, and the defect that the fixing orthosis is always fixed at a strong flexion position after the operation is overcome.
