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 second osteotomy should be made perpendicular to the axis of the hemkmelia diaphysis of the tibia. Orthopedic treatment aims at correcting the leg length discrepancy, and, in bilateral cases, correcting the asymmetrical dwarfism.
Parents of males treated by amputation perceived a lower school-related QoL for their child, a finding possibly explainable by socio-economic and ethnic differences between the groups. A schedule for lengthening is given to the patient.
This anlage may be fibrous or both fibrous and cartilaginous. Therefore, the ankle joint functions for both the ankle and subtalar joints. Research has demonstrated that if the genes guiding the formation of the limb are activated in an abnormal order, fibular hemimelia can occur. The fibula is hypoplastic. Check this box if you wish to receive a copy of your message. Furthermore, the child and later the adult with the prosthesis must have an expensive high-quality technically advanced prosthesis made every year throughout childhood and frequently every year throughout adult life.
They may order these tests to learn more:. The interosseous membrane is also released through this incision. Femoral lengthening Femoral lengthening can be combined with the tibial lengthening at the same time or at a separate time to treat concomitant shortening of the femur.
Most cases are sporadic. Push-off strength was conserved, and no supination deformity resulted.
The results of the comparison demonstrated no difference in function between the two groups. The big toe may also be pointing inwards, away from the rest of the foot.
J Bone Joint Surg Br. At the end of the reconstruction 35 of the patients had a plantigrade, functional foot, and the remaining two patients had residual valgus deformity, requiring shoes with orthoses. Make the distal osteotomy in the plane of the distal guide wires. And then re-advanced across the osteotomy site Fig. The logic of this does not follow since for a foot deformity the recommendation is to correct the foot and for a leg length discrepancy the recommendation is to lengthen the leg; therefore, should not the recommendation for a foot deformity with a hemmielia length discrepancy be to correct the foot fivular and lengthen the leg?
A family history has been reported fibulag a small percentage of cases with an autosomal dominant pattern of inheritance and incomplete penetrance. Fibular hemimelia or longitudinal fibular deficiency is “the congenital absence of the fibula and it is the most common congenital absence of long bone of the extremities.
Management requires a multidisciplinary approach genetic counselors, perinatologists and pediatric orthopedic surgeons. The origin is unclear but follows a pattern similar to that seen with the Cozen phenomenon [ 27 ] after proximal tibial metaphyseal fractures.
It is currently unknown why fibular hemimelia occurs. In addition to ankle deformities, the foot in patients with FH may also have a deformity between the talus ankle and calcaneus heel bone.
If the subtalar coalition connects the talus and calcaneus in a normal position such that the heel is in line with fibupar ankle bone, then it does not contribute to additional deformity of the foot. No prosthesis provides sensibility or proprioception. Look out for the superficial peroneal nerve as it exits the fascia. It is the most common long bone deficiency and is the most common skeletal deformity in the leg.
Arthrogryposis Larsen syndrome Rapadilino syndrome. The superficial peroneal nerve is decompressed and protected.
This subtalar coalition usually involves the posterior facet and is often malunited into equino-valgus. Absence or weakness of the peroneus longus may lead to overpull of the tibialis anterior and elevation of the first metatarsal with compensatory flexion of the first metatarsophalangeal joint fubular bunion.
Paley D, Guardo F Lengthening reconstruction surgery for congenital femoral deficiency. Free the distal end of the anlage from the calcaneus and then fold it over to pass it out the proximal incision by tunneling between the two incisions.

Surgical reconstruction for fibular hemimelia
Despite fusion of the bones, side-to-side motion is present in FH due to an abnormal, ball-and-socket shaping of the ankle joint. Catagni MA, Guerreschi F. If the distal hemimeli joint is not stable, insert a syndesmotic double washer compression suture such as a TightRope Arthrex Inc. The ankle joint is primarily made up of the lower end of the tibia, which is often severely deformed as well in patients with fibular hemimelia.
Fibular hemimelia – Wikipedia
Congenital longitudinal deficiency hhemimelia the fibula fibular hemimelia: Birch J, Paley D Limb reconstruction or amputation provide similar function and quality of life for fibular hemimelia. No one would dispute that amputation with prosthetic fitting requires fewer surgical interventions and fewer days of hospitalization and is associated with a lower complication rate. Unilateral involvement occurs in two-thirds of cases, with the right fibula being affected more often than the left.
Miller and Bell [ 45 ] reported the outcomes of 12 lengthenings in cases of FH. In contrast to the post lengthening tibial valgus, femoral valgus associated with FH is nonprogressive [ 29 hemimeelia.
