The Arthrogrypotic Foot Plan of Management and Results of Treatment
SAGE Publications - Tập 3 Số 4 - Trang 211-219 - 1983
Fifty-one arthrogrypotic feet have been treated and followed by the Pediatric
Orthopaedic Unit, Tufts New England Medical Center, (1970–1980). Forty of the 51
feet presented as equinovarus with the residual divided among metatarsus
adductus, vertical tali, and calcaneo-valgus. Equinovarus deformities are the
most resistant in all cases. Corrective casts are applied for at least the first
3 months ...
Foot Pressure Studies in the Assessment of Forefoot Arthroplasty in the Rheumatoid Foot
SAGE Publications - Tập 8 Số 6 - Trang 315-326 - 1988
To assess the results of forefoot arthroplasty, dynamic and static foot pressure
studies have been made of the rheumatoid foot in both a prospective study group
of 60 feet and in a retrospective study group of 18 feet. Significant reductions
of pressure in the forefoot were found. Problems associated with the first and
fifth metatarsals were considered.
The Measurement of Pressures under the Foot
SAGE Publications - Tập 3 Số 3 - Trang 130-141 - 1982
An apparatus is described which gives a rapid and detailed picture of the
distribution of pressure under the foot, this being displayed either as a
continuous grey scale or a color contour map on a television monitor. Automatic
analysis systems are outlined which enable the quantitation of the distribution
of pressures and loads under the foot during standing and walking, utilizing
computer techni...
Anatomical Considerations of Posterior Tibialis Tendon Entrapment in Irreducible Lateral Subtalar Dislocation
SAGE Publications - Tập 13 Số 8 - Trang 458-461 - 1992
Irreducible lateral subtalar dislocation is associated with posterior tibialis
tendon entrapment. Mulroy 7 and Leitner 6 have proposed conflicting theories
regarding the exact mechanism of tendon entrapment. Cadaveric analysis of
lateral subtalar dislocation supported Leitner's 5 contention that tearing of
the flexor retinaculum promotes posterior tibialis tendon entrapment.
Retinacular disruption...
Evolution of the Human Foot: Evidence from Plio-Pleistocene Hominids
SAGE Publications - Tập 3 Số 6 - Trang 365-376 - 1983
The human foot serves a dual role during locomotion. It functions at times as a
mobile structure and at times as a rigid lever. The human foot shows the
hallmarks of an arboreal heritage wherein the foot was primarily a grasping
organ. Over the course of the human career the human foot has evolved an
elaborate plantar aponeurosis, strong plantar ligaments, longitudinal arches, an
enlarged musculus...
In Vitro Determination of Midfoot Motion
SAGE Publications - Tập 10 Số 3 - Trang 140-146 - 1989
Midfoot motion was determined using an in vitro model. Ten fresh-frozen
below-the-knee amputation specimens were instrumented by inserting reference
pins into each of the bones of the hindfoot, midfoot and metatarsals.
Dorsiflexion-plantar flexion and supination-pronation were simulated and the
reference pin location in three dimensional space was determined. Comparing the
location of the referenc...
Kinematics of the Ankle/Foot Complex—Part 3: Influence of Leg Rotation
SAGE Publications - Tập 9 Số 6 - Trang 304-309 - 1989
In an in vivo kinematical investigation, the movements of the ankle/foot complex
induced by external rotation of the leg from an internally rotated position were
analyzed by roentgen stereophotogrammetry. Radiopaque markers were introduced
into the tibia, talus, calcaneus, navicular, medial cuneiform, and first
metatarsal bones of eight healthy volunteers. Rotations occurring between these
bones a...
Kinematics of the Ankle/Foot Complex—Part 2: Pronation and Supination
SAGE Publications - Tập 9 Số 5 - Trang 248-253 - 1989
The influence of pronation and supination of the foot on the joints of the
ankle/foot complex was analyzed three dimensionally by roentgen
stereophotogrammetry in eight healthy volunteers. Radiopaque markers were
introduced into the tibia, talus, calcaneus, navicular, medial cuneiform, and
first metatarsal bones. The subjects stood on a platform that was tilted in
10°-steps from 20° of pronation t...
Kinematics of the Ankle/Foot Complex: Plantarflexion and Dorsiflexion
SAGE Publications - Tập 9 Số 4 - Trang 194-200 - 1989
In an in vivo investigation of eight healthy volunteers, three dimensional
ankle/foot kinematics were analyzed by roentgen stereophotogrammetry in 10°
steps of motion from 30° of plantar flexion to 30° of dorsiflexion of the foot.
The study included all of the joints between the tibia and the first metatarsal,
as well as the talocalcaneal joint, and was performed under full body load.
Although the...
Selective Tarsal Arthrodesis: An in Vitro Analysis of the Effect on Foot Motion
SAGE Publications - Tập 8 Số 3 - Trang 127-133 - 1987
Five different intertarsal arthrodeses were simulated in 15 fresh cadaver
feet/ankles utilizing external fixation. Pin placement was verified
radiographically. Range of motion measurements were performed before pin
placement, after pin placement, and after simulated arthrodesis. The deficit in
foot motion created by selected limited intertarsal fusions was then measured.
The prearthrodesis range o...
