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.

Paley presented unpublished results presented at AAOSAnaheim, California similar results to those of these last three studies.
The fibula is hypoplastic. An analysis of the unsatisfactory results reported in different series in the literature [ 36 — 3842 ] makes it clear that the overriding factor associated with poor results is recurrent or residual foot fibhlar tibial deformities—and not the inability to obtain equalization of limb length.
In some cases it may actually be fused to the calcaneus. A family history has been reported in a small percentage of cases with an autosomal dominant fibulr of inheritance and incomplete penetrance. Growth inhibition has been reported after tibial lengthening for FH [ 30 ].
Views Read Edit View history. The distal tibial articular surface is fibulaf concave in the frontal plane as part of a ball and socket ankle joint. Others need surgery to stand and walk.
Fibular Deficiency (anteromedial bowing)
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. Despite complications, the final result was not related to the complication rate.
Obviously, simultaneous femoral and tibial lengthening can yield much larger amounts of lengthening in one treatment than tibia lengthening alone.
A 6-month-old fiblar presents with Paley type 3c FH. Despite this, the results of some clubfoot treatments leave the child with chronic pain and a stiff deformed foot that might be better treated by amputation and prosthetic fitting. The end of the fibula can be felt as a large bump on the lateral sides of our ankles, called the lateral malleolus.
Insert a wire from the medial side perpendicular to the tibia at the shortening distance away from the distal tibial frontal plane wire at the lateral cortex. Identify the sinus tarsi and the posterior border of the calcaneus where it lies against the tibia Fig. For more information, see Toe Reconstruction. They are fixed and tensioned to a full ring which passes circumferentially around the foot Fig.
Beyond the hindfoot hemimellia there can be deformities of the midfoot.
Fibular Hemimelia (for Parents)
If femoral lengthening is considered, it is factored into the surgical life plan discussed previously. The ankle joint function with FH may range from: Paley D, Guardo F Lengthening reconstruction surgery for congenital femoral deficiency. The foot is generally in an equinovalgus position. Identify the lateral border of the hemiemlia muscle and find its tendinous apponeurosis. It its resistant to Ponsetti casting as well as clubfoot releases of the subtalar joint since there is a subtalar coalition.
Why is amputation offered as the main treatment option? Its cut surfaces should remain in contact. The child with a limb deficiency. In such situations, amputation is contraindicated. Use these two wires to guide the proximal osteotomy plane of cut Figs.
This moment arm is normally resisted by the posterior tibial tendon during the stance phase of gait. It also does not factor in that children and adults with FH with missing knee ligaments who have added stress due to the lever arm of a prosthesis can develop secondary problems at the knee joint.
The orthotist will adjust the prosthesis or make a new one as fbiular child grows. Find the separation between the gastrocnemius muscle and the peroneal muscles.
