Limb lengthening over plate.
BACKGROUND
The limb lengthening over plate eliminates the associated risk of infection with limb lengthening over intramedullary nail. We present our experience of limb lengthening in 15 patients with a plate fixed on the proximal segment, followed by corticotomy and application of external fixator.


METHODS
15 patients (7 females, 8 males) were included in this consecutive series. The average age was 18.1 years (range 8-35 years). Fifteen tibiae and one femur were lengthened in 15 patients. Lengthening was achieved at 1 mm/day followed by distal segment fixation with three or four screws on reaching the target length.


RESULTS
The preoperative target length was successfully achieved in all patients at a mean of 4.1 cm (range 1.8-6.5 cm). The mean duration of external fixation was 75.3 days (range 33-116 days) with the mean external fixation index at 19.2 days/cm (range 10.0-38.3 days/cm). One patient suffered deep infection up to the plate, three patients had mild procurvatum deformities, and one patient developed mild tendo achilles contracture.


CONCLUSIONS
Lengthening over a plate allows early removal of external fixator and eliminates the risk of creating deep intramedullary infection as with lengthening over nail. Lengthening over plate is also applicable to children with open physis.
