94 Possible Causes for Curvatures of the Femur, Tibia, Fibula, Flattening of the Talar Dome, Mutation in the PHEX Gene

  • Tibia Varum

    Usually there is an outward curvature of both femur and tibia.[] Fibula The fibula is the slender lateral bone of the leg.[] Synonym(s): bowleg , bow-leg , tibia vara . bowleg ; genu varum ; tibia varum frontal-plane malalignment of one or both lower limbs, characterized by bowing along (1) full[] Genetic testing attributed the condition to mutations in the PHEX gene located at Xp22.1.[] Usually there is an outward curvature of both femur and tibia, with at times an interior bend of the latter bone.[]

  • X-Linked Hypophosphatemia

    Reported skeletal abnormalities included bowing of the tibia/fibula (52/71 (73%)), bowing of the femur (45/71 (63%)), gait disturbance (61/71 (86%)), joint pain (46/71 (65%[] […] shortening of the talar neck and flattening of the talar dome.[] Neither height nor bowing angles of femurs or tibias at presentation predicted the need for future osteotomies.[] To date, 131 mutations in the PHEX gene have been reported.[] […] associated with a waddling gait, confirmed by radiographic findings: varus of the tibias, fraying of the distal metaphyseal region of both femurs and tibias, and cupping of both fibulas[]

  • Ankle Arthritis

    Joint is between the lower end of tibia and fibula. Ankle joint arthritis of tibio-fibular joint is rare.[] Relative radiographic contraindications to performing an ankle distraction include flattening of the talar dome, presence of greater than five degrees of valgus or varus deformity[] Of the 25 patients, 23 showed FHL involvement, 21 FDL, 21 TP, 15 PL, 15 PB, three EDL, 21 subtalar joint, six talus, six tibia, and five calcaneus on MR images.[] The primary goal of the procedure is to realign the spatial relationship between the talus and tibia and thereby normalize joint loading within the ankle.[] Associated deformities may also be addressed with supramalleolar osteotomies, tibia or fibular lengthening, and calcaneal osteotomies.[]

  • Weismann Netter Syndrome

    […] outward curvature of the tibia (saber shins).[] , broadening of the fibula, posterior cortical thickening of both bones and short stature.[] The presence of tibialization of the fibulae, the fibula bone acting as tibia, is highly specific to the disorder.[] The diagnostic findings of WNS are anterior bowing of the diaphyses of tibia and fibula, broadening or "tibialization" of the fibula and posterior cortical thickening of the[] , broadening or 'tibialization' of the fibula, posterior cortical thickening of both bones, and short stature.[]

    […] of the femur, tibia, fibula, enlargement of the wrists, enlargement of the ankles, and subperiosteal erosions due to secondary hyperparathyroidism.[] XLH is considered to be a systemic disorder, from mutation of the phosphate-regulating gene homologous to endopeptidases on the X chromosome ( PHEX ).[] Clinical course : Depending on the degree of distortion, pseudoarthrosis of the lower leg (false joint formation of the tibia and possibly fibula ) may be present at birth[] Mutational analysis and genotype-phenotype correlation of the PHEX gene in X-linked hypophosphatemic rickets.
