“…Internal mechanical telescoping nails have been used to accomplish DO, although presented with numerous complications (76%), including uncontrolled rapid lengthening (21.4%), absence of lengthening (39.3%), and lack of bone regenerate consolidations (32.1%). 34 Other telescoping IMNs present with a similar complication profile, although it must be noted that the apparent complication incidence may be significantly lower compared with mechanical nail counterparts. 35,36 Originally available in 2019, the BTN allows for BT using a single implant all-internal magnet-driven IMN.…”

A single implant all-internal magnet-driven bone transport nail (BTN-NuVasive Specialized Orthopaedics Inc) has recently been introduced as a treatment method for segmental tibial bone defects. This innovation provides promise in the management of segmental bone defects because it negates numerous complications associated with circular external fixation and the need for multiple implants when considering hybrid plate-assisted bone segment transport constructs. Given the novelty of the BTN, description of the surgical application and patient outcome measures are scarce in the current literature. To date, we have treated 4 patients with an average age of 27 years (range 19-44 years) using the BTN for segmental tibial defects ranging from 50 to 128 mm. We have accumulated data over an average follow-up of 18.07 months (range 12.96-25.13 months), demonstrating good patient tolerance of the device. Three patients successfully completed their treatment course with a calculated average bone healing index of 41.4 days/cm (range 31.41-54.82 days/cm). One patient was noted to experience an asymptomatic docking site nonunion requiring subsequent surgery for nonunion repair. Implant-associated complications included symptomatic implant, axial malalignment, docking site nonunion, and external remote control technical malfunction. Injury-related complications were encountered and noted to include: superficial infection, wound dehiscence, peroneal tendonitis, and joint rigidity. In this study, the authors present a case series using this implant to date and discuss our experiences with the BTN with reference to clinical indications, tibial bone preparation, BTN implantation, transport protocol, docking site procedure, and clinical/radiographic outcomes.

“…The excessive "runaway" distraction of this device resulted in poor bone regenerate and non-union. Based on this fact, Lecoanet et al have recommended that this system should no longer be used due to the improved control of lengthening rate and fewer complications encountered with the motorized driven nails [25] . It should be noted that the implant was withdrawn from the US market in 2012.…”
