Does the external remote controller's reading correspond to the actual lengthening in magnetic-controlled growing rods?

Purpose: Magnetic-controlled growing rods (MCGRs) are now routinely used in many centres to treat early-onset scoliosis (EOS). MCGR lengthening is done non-invasively by the external remote controller (ERC). Our experience suggests that there may be a discrepancy between the reported rod lengthening on the ERC and the actual rod lengthening.

Do magnetic growing rods have lower complication rates compared with conventional growing rods?

Background Context: The main advantage cited for the use of the magnetic controlled growing rod (MCGR) system over the conventional growing rod (CGR) in early-onset scoliosis is avoiding repeated invasive surgical procedures for lengthening, thus reducing, complications.

Purpose: The study aimed to evaluate the complications of the MCGR system against the CGR system in our center.

Study Design/setting: This is a retrospective case control series.

Magnetic controlled growing rods for early-onset scoliosis: a 4-year follow-up.

Background Context: There have been no studies with medium-term follow-up of magnetic controlled growing rods (MCGRs).

Purpose: This study aimed to report our single center experience of a magnetic growing rod system with an average of 4 years' follow-up.

Study Design/setting: A retrospective case series was carried out.

Spontaneous locking of the knee after anterior cruciate ligament reconstruction as a result of a broken tibial fixation device.

The Intrafix device (DePuy Mitek, Raynham, MA) is one of a number of recently developed products whose aim is to improve fixation of quadrupled hamstring grafts when used for anterior cruciate ligament reconstruction. We present a case of failure and intra-articular migration of the sleeve of an Intrafix device causing locking of the knee 10 weeks after anterior cruciate ligament reconstruction. We were unable to identify the cause of the failure or migration of the device.
