Pedorthics Final Exam Study Guide Questions with Complete Solutions 100% Verified What does a pedorthist do? - Correct Answer A pedorthist understands the properties of footwear and the interaction between a patient's foot and the device or shoe, which makes them skilled at evaluating feet and fitting footwear Anatomical planes - Correct Answer Coronal, sagittal, transverse Columns of the foot - Correct Answer Medial - 1st metatarsal, medial cuneiform Middle - 2nd/3rd metatarsal, intermediate/lateral cuneiform Lateral - 4th/5th metatarsal, cuboid Sections of the foot - Correct Answer Forefoot - distal phalanges 1-5, intermediate phalanges 2-5, proximal phalanges 1-5, metatarsals 1-5 Midfoot - medial/intermediate/lateral cuneiforms, cuboid, navicular Hindfoot (rearfoot) - talus, calcaneus Name the joints of the foot and ankle complex - Correct Answer Talocrural (ankle); subtalar (talocalcaneal); transverse tarsal (midtarsal, Chopart) [talonavicular, calcaneocuboid]; tarsometatarsal (Lisfranc); metatarsophalangeal (MTP); proximal/distal interphalangeal (PIPs, DIPs) Type of joint & motions: talocrural - Correct Answer Hinge; dorsiflexion, plantarflexion Type of joint & motions: subtalar - Correct Answer Oblique condyloid; pronosupination Type of joint & motions: transverse tarsal - Correct Answer TN - ball & socket; inversion, eversion CC - modified saddle; inversion, eversion [oblique, longitudinal] Type of joint & motions: tarsometatarsal - Correct Answer Planar 1 / 3
Type of joint & motions: metatarsophalangeal - Correct Answer Condyloid; DF, PF, adduction, abduction, circumduction Type of joint & motions: interphalangeal - Correct Answer Hinge; flexion, extension Four levels of PF amputation - Correct Answer Subtalar, Chopart, Lisfranc, MTP
- purposes of the foot - Correct Answer Shock absorption, rigid propulsion, adverse terrain, structural
platform Three arches of the foot - Correct Answer Medial longitudinal, lateral longitudinal, transverse Bones of medial arch - Correct Answer Calcaneus, navicular, all 3 cuneiforms, mets 1-3 Bones of the lateral arch - Correct Answer Lateral tubercle of calcaneus, cuboid, mets 4-5 Bones of the transverse arch - Correct Answer Cuneiforms, cuboid, metatarsals 1-5 Ligaments of medial arch - Correct Answer Plantar calcaneonavicular (spring), plantar aponeurosis, short/long plantar Ligaments of the lateral arch - Correct Answer Short & long plantar Ligaments of the transverse arch - Correct Answer Deep transverse ligaments Muscles of medial arch - Correct Answer Tibialis anterior, tibialis posterior, flexor hallucis longus, gastrocnemius, soleus Muscles of lateral arch - Correct Answer Peroneus longus, peroneus brevis, plantar fascia, intrinsics 2 / 3
Muscles of transverse arch - Correct Answer Adductor hallucis, interossei, peroneus longus, peroneus brevis Bones that form the basis of weight bearing - Correct Answer Met heads (specifically 1,5), calcaneus Column that is most weight bearing - Correct Answer Lateral Which is the stronger side of the ankle and why? - Correct Answer Lateral; ligament positioning & fibula bony stop What determines the motion of each joint? - Correct Answer Angle of joint (oblique) Motion of talocrural joint axis - Correct Answer See saw Motion of subtalar joint axis - Correct Answer Triplanar motion Plane, section, joint: dorsiflexion & plantarflexion - Correct Answer Plane - sagittal Section - ankle; hindfoot Joint - talocrural; subtalar Plane, section, joint: inversion & eversion - Correct Answer Plane - coronal Section - hindfoot; forefoot Joint - subtalar; tarsometatarsal Plane, section, joint: abduction & adduction - Correct Answer Plane - transverse Section - forefoot Joint - tarsometatarsal
