Purpose Management of fibular hemimelia includes either prosthetic care with or without a suitable amputation or tibial lengthening. Many studies have documented the success of both procedures. Most parents of these children refuse an amputation or have no access to good prosthetic care. The author presents a limb-salvage procedure with tibial lengthening and ankle stabilization. Methods Twelve children of fibular hemimelia with 14 extremities had been subjected to limb lengthening after lateral leg release. To correct the valgus procurvatum, double oblique diaphyseal osteotomy (DODO) of the tibia was performed in 11 extremities. The age of the patients ranged from two to 15 years with the median of five years. All were male. The proposed procedure included three stages of loosening, lengthening, and stabilization with ankle arthrodesis at a later stage. Results All patients returned for follow-up for the first four years and had been walking on their sensate feet. With DODO followed by fixator/traction could straighten and lengthen the tibia simultaneously and correct the valgus procurvatum. Ankle stabilization provided stability and a plantigrade foot. A follow-up of six to 30 years with a median of ten years has been reported. Conclusion A new procedure of loosening, lengthening, and stabilization of the leg with ankle arthrodesis has been proposed. A follow-up of 30 years with a median of ten years of the said procedure has been reported. The procedure provides a long-lasting plantigrade and painless foot that has sensation and proprioception. An amputation at any level has not been recommended.
