Motorized Internal Lengthening of Long Bones: Residual Limb Lengthening

Techniques in Orthopaedics, 2020
Distraction osteogenesis can be performed for transfemoral amputees using a motorized intramedullary limb lengthening nail (LLN) such as the 14×130 mm NuVasive Freedom nail. Despite being the shortest commercially available LLN, some patients have even shorter residual femurs, making it impossible to link the bone to the nail by the standard technique ...

Fibula-Assisted Segment Transport (FAST) for Defect Reconstruction after Resection of Tibial Adamantinoma: Report of Two Treatments

Case Reports in Orthopedics, 2021
Intramedullary limb lengthening via lengthening nails has been performed for more than three decades to overcome leg length inequalities. Plate-assisted bone segment transport (PABST) has recently been described for the reconstruction of segmental bone ...

Calcaneal lengthening using ipsilateral fibula autograft in the treatment of symptomatic pes valgus in adolescents

BMC Musculoskeletal Disorders, 2021
Background Evans calcaneal lengthening osteotomy is used to treat symptomatic flexible flatfoot when conservative treatment fails. Grafts such as autologous iliac bone grafts, allografts, and xenografts are implanted at the osteotomy site to lengthen the
