Effects of a telescopic intramedullary rod for treating patients with osteogenesis imperfecta of the femur

Abstract

PurposeTo introduce a new model of telescopic intramedullary rod (TIR), evaluate its effects on treating patients presenting with moderate and severe osteogenesis imperfecta (OI) and to compare the findings with those of other telescopic rods.MethodsA total of 21 patients (nine girls and 12 boys; mean age at first operation, 6.6 years, 1.52 to 13.18) who underwent 52 femoral operations were monitored during a mean of 9.96 years (3.39 to 14.54). Patient characteristics, telescoping rod capability and its complications were examined.ResultsAccording to the Sillence classification, we investigated one patient with type I, nine with type III and 11 with type IV OI. Revision rates at up to five years (36%) were inferior to those found for the Fassier-Duval rod (46%). The main cause of revision was fracture (15 patients), followed by rod migration (nine), and infection (two). The rod exhibited higher telescopic capacity in boys than girls. Type III most commonly required an operation; the age group with the highest number of procedures was five to ten years. Male migration was the main cause of rod migration.ConclusionThe TIR has a satisfactory cost-benefit ratio with less complication rates and low production costs. The TIR is a feasible alternative to the commonly used Fassier-Duval rod.Level of EvidenceIV

Dislodgement of Telescopic Nail from the Epiphysis: A Case Report with an Analysis of Probable Mechanism

“…Although elongating rods have the benefit of expanding as the bone grows, non-elongating rods are still preferred when treating either the too young, whose bones are too small to support telescopic rods, or those nearing skeletal maturity whose bones are no longer expected to grow [11]. Several single proximal-entry telescopic nails have been developed after the Bailey-Dubow and Sheffield rod, such as the Santa Casa telescopic intramedullary rod, Dyna-Locking Telescopic Rod, and the Fassier-Duval (FD) nail [7,12]. FD nails have widespread acceptance in several pediatric orthopedic centers around the world.…”

Surgical treatment of comminuted intraarticular distal femur fracture in patient with osteogenesis imperfecta type I

“…Часто причиной падения служит нестабильность коленных суставов на фоне гиперэластичности и постиммобилизационной гипотрофии мышц. Применение индивидуальных шарнирных ортезов в послеоперационном периоде помогает решить эту проблему [8]. Дети с НО переносят множественные переломы, многие из них испытывают страх получить новую травму на этапе реабилитации [1].…”

“…Комбинация переломов, с которой мы столкнулись в данном клиническом случае, встречается крайне редко. Большинство публикаций посвящено лечению диафизарных переломов [7][8][9][10][11], нам не удалось найти публикаций, в которых бы описывалось лечение внутрисуставных переломов дистальной трети бедренной кости у детей с НО.…”

Impact of Transphyseal Elastic Nailing On the Histostructure of the Tibia in Growing Animals (Non-Randomized Controlled Experimental Study)

“…Osteogenesis imperfecta (OI) is a systemic bone disease that is accompanied by bone fragility that results in fractures and deformities [ 1 ] [ 2 ]. In 1987, J.P. Metaizeau proposed the use of counter directed intramedullary transphyseal elastic nailing to prevent deformities and treat fractures of the tubular bones.…”

“…In 1987, J.P. Metaizeau proposed the use of counter directed intramedullary transphyseal elastic nailing to prevent deformities and treat fractures of the tubular bones. Currently, the use of transphyseal intramedullary nailing is a method of choice for prevention and treatment of complications in OI children [ 1 ] [ 2 ] [ 3 ] [ 4 ] [ 5 ] [ 6 ]. The advantage of elastic rods is the possibility to use them in a small bone canal, which is characteristic for OI children [ 3 ] [ 7 ].…”
