Congenital tibial pseudarthrosis, changes in treatment protocol

Area of Science:

• Orthopedic Surgery
• Pediatric Orthopedics
• Regenerative Medicine

Background:

• Congenital pseudarthrosis of the tibia (CPT) presents a significant challenge in pediatric orthopedics.
• Nonunion of the tibia can lead to limb deformity, shortening, and functional impairment.

Purpose of the Study:

• To evaluate the efficacy of a multi-stage surgical protocol for treating CPT in children.
• To assess the outcomes of combining bone grafting, intramedullary fixation, and limb lengthening.

Main Methods:

• Ten children with CPT underwent resection of pathologic bone, bone grafting, and intramedullary rodding.
• Simultaneous proximal tibia lengthening and compression with a circular frame were employed.
• Recombinant human bone morphogenetic protein was used in some cases.

Main Results:

• Complete union of the pseudarthrosis was achieved in all ten patients.
• Limb lengthening up to 5 cm was successfully accomplished.
• Four patients required additional procedures for residual valgus deformities or shortening.

Conclusions:

• The described multi-modal surgical protocol is effective for achieving union in CPT.
• Addressing ankle joint alignment is essential for restoring full limb functionality.
