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.

Hemimeliia in physical therapy In addition to ankle deformities, the foot in patients with FH may also have a deformity between the talus ankle and calcaneus heel bone.

Surgical reconstruction for fibular hemimelia

Rarely, fibular hemimelia is associated with nonskeletal malformations eye abnormalities such as anterior chamber anomalies or anophthalmia, cardiac anomalies, renal dysplasia, thrombocytopenia, thoracoabdominal schisis, spina bifida and, rarely, intellectual deficit.

Insert one frontal plane 12 and one sagittal plane 34 guide wire at each level of planned osteotomy. Management and treatment Management requires a multidisciplinary approach genetic counselors, perinatologists and pediatric orthopedic surgeons. Excellent function could also be obtained if amputation and prosthetic fitting were used to treat clubfoot, ankle arthritis or other disabling foot conditions.

Toe and metatarsal surgery Many patients with FH are missing one or more toes. Management requires a multidisciplinary approach genetic counselors, perinatologists and pediatric orthopedic surgeons. Insert supramalleolar tibial guide wires in the frontal and sagittal planes parallel to the plantar aspect of the foot as distal as possible without crossing the distal tibial physis Fig.

Surgical reconstruction for fibular hemimelia

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 leg length discrepancy be to correct the foot deformity and lengthen the leg? The distal fibular physis is proximal to the level of the ankle joint.


There were no permanent sequelae of knee subluxation, hip subluxation, nerve injury, nonunion or osteomyelitis in any patient. In an experimental mouse model, change in the expression of a homeobox gene led to similar, but bilateral, fibular defects.

No patient underwent ankle arthrodesis. Purportedly, there have been some incidents of genetic distribution in a family; [ citation needed ] however, this does not account for all cases.

This malorientation points the foot towards the outside lateral hemi,elia down posteriorcreating what is called an equinovalgus deformity. Note hemimleia a subtalar coalition is present. Genetic counseling Most cases are sporadic. Normally, there are five metatarsals and five toes, but in fibular hemimelia there may be more or less.

Perform a proximal osteotomy for lengthening c. Fibular hemimelia FH is a very rare disorder, occurring in only 1 in 40, births. Pin the talus to the tibia with one medial antegrade wire and one medial retrograde wire. Growth inhibition has been reported after tibial lengthening for FH [ 30 ].


Fibular Deficiency (anteromedial bowing) – Pediatrics – Orthobullets

A bracket first metatarsal or a bracket conjoined first and second metatarsal with hallux varus is not uncommon. In such cases, it is not unusual to perform the SUPERankle procedure with application of the external fixator for lengthening tibia and femur.

Reproduced with permission by the Paley Foundation. In moderate limb length inequality, limb lengthening is an option but it carries the risk of requiring multiple reconstructive procedures and complications.

Fiblar one patient who was rated as having achieved only a fair result had a residual equinus deformity with a painful arthritic ankle and required an ankle fusion.

The child with a limb deficiency. A skin dimple is usually present fobular the apex of this angulation.


Fibular hemimelia

The second osteotomy should be made perpendicular to the axis of the proximal diaphysis of the tibia. This includes one anteromedial and anterolateral half pin proximally and two half pins and a wire in the tibia distally Fig. It should slide medial-distally and not wedge open on the lateral side.

These results using the Ilizarov apparatus are not much different from those reported by Choi et al. The extent of ankle joint deficiency may range from a relatively normal ankle to a very unstable, abnormally-shaped ankle with limited mobility.

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. Classification of FH Fig.

Example of reconstructive life plan A 6-month-old boy presents with Paley type 3c FH. The origin is unclear but follows a pattern similar to that seen with the Cozen phenomenon [ 27 ] after proximal tibial fiblar fractures. Scores on psychosocial and QoL surveys tended to be commensurate with those from healthy patient populations in both groups.

The cause of fibular hemimelia is unclear. Osteotomize the distal tibia parallel to these guide wires Fig. Is it because these cases are unreconstructable or is it fibulat of fundamental errors in the treatment strategy used?

Children between the ages of 4. Therefore, the ankle joint functions for both the ankle and subtalar joints.

Add a walking ring and secure axial wires to the frame. Doctors do different surgeries depending on a child’s situation.

No initial treatment for this is provided but ligament reconstruction should be considered if the patient begins to develop problems of knee instability. All but three limbs had regained their preoperative range of ankle motion.
