Also known as congenital absence of the fibula, congenital fibular deficiency, paraxial fibular hemimelia and aplasia/hypoplasia of the fibula, fibular hemimelia . Fibular hemimelia. Disease definition. Fibular hemimelia is a congenital longitudinal limb deficiency characterized by complete or partial absence of the fibula. consists of shortening or entire absence of the fibula; previously known as fibular hemimelia; the most common congenital long bone deficiency.

The next step is to determine what type of FH. Start by inserting wires in foot parallel to sole a. Only comments written in English can be processed. A growth plate is an area at the end of the bone where new growth happens. If the deformity is from the tibia, and if tibial lengthening is carried out, then the deformity can be corrected through the lengthening osteotomy of the proximal tibia.
Severe tibial growth retardation in total fibular fiblar after limb lengthening. One or more rays may be missing, making the foot narrower. Previous classifications have focused on the degree of fibular deficiency rather than the type of foot deformity. This interaction is the reason why even small amounts of loss of length or position of the fibula after ankle fracture can lead to lateral subluxation of the talus in the mortise and eventually ankle arthritis [ 23 ].
Children with deficient or absent cruciate ligaments often do very well and can engage actively in various sports that other children their age can participate in. The new bone formation is excellent. These guide wires are inserted at fibulxr angle of the plane of the osteotomy. Prognosis Fibular deficiency is usually a benign condition, although in severe cases it can be debilitating. Example of reconstructive life plan A 6-month-old boy presents with Paley type 3c FH.
The lateral moment arm is also blocked by the buttressing effect of the lateral malleolus. Genetic counseling Most cases are sporadic.
They work with other specialists as needed. In the grade 3 FH group, two patients required six tibular of reconstruction a stage referred to as a lengthening or a deformity correctionfour required five stages, six required four stages, three required three stages, four required two stages and one required one stage.
Dissect distally along this anlage Fig. This takes time and patience to get the calcaneus to move. Abstract Fibular hemimelia presents with foot deformity and leg length discrepancy. Identify the sinus tarsi and the posterior border of the calcaneus where it lies against the tibia Fig. It should slide medial-distally and not wedge open on the lateral side. Therefore, the different groups of FH that have been described in the various classifications do not relate to the different types of treatment that are currently available.
For type 4, carry out the procedure as for type 3C with a closing wedge osteotomy of hemimeoia subtalar coalition, medializing and tilting the talus into valgus instead of varus since there is a varus malunion as opposed to the valgus malunion seen in types 3B and C.
Fibular Deficiency (anteromedial bowing) – Pediatrics – Orthobullets
If the distal tibiofibular joint is not stable, insert a syndesmotic double washer compression suture such as a TightRope Arthrex Inc. The device might be on the outside of the body or inside the bone. For these kids, a prosthesis offers the best chance to live an active life. It is important to realign the knee during treatment of fibular hemimelia.
Hopefully, with greater awareness centers of excellence can develop this expertise, and it will be offered as an alternative and perhaps one day replace amputation surgery for FH.
This valgus is related both to the distal femur and the proximal tibia. Elimination of the lateral shift of the talus in the mortis when the fibula is missing requires medialization of the ground reaction force vector by shifting the point of contact of the calcaneus with the ground.
Surgical reconstruction for fibular hemimelia
Paley D Treatment congenital femoral deficiency. The major functional deficiency results from leg length discrepancy in unilateral cases or asymmetrical dwarfism in bilateral cases.
Some children with fibular hemimelia have very mild limb length difference and need very little treatment.
Excellent function could also be obtained if amputation and prosthetic fitting were used to treat clubfoot, ankle arthritis or other disabling foot conditions.
Your child’s team also might include physical therapists and an orthotist. He stands on the outer border of his foot. Summary Epidemiology Prevalence is estimated at 1 in 50, In addition, many patients with FH have a slower growing femur as well.
