Methods and materials
The results of radiographic and ultrasound examination of 64 patients (average age 11.6±2.3 years) with congenital limb shortening and deformation were analyzed (fig.1).
All patients were divided into two groups: group I – patients aged 6-10 years (n=34),
group II – aged 11-15 years (n=30).
X-ray examination was performed before the surgical treatment.
Osteotomy was made to correct deformation and elongate limbs.
Compression-distraction osteosynthesis with a rod external fixator was performed.
Distraction started between 4-6 days after surgery,
and this fact conforms with the findings in the available literature [1,
2].
The average gain in length was of 5.2±1.8 сm,
distraction period lasted 52.0±4.0 days at a rate of 0.75-1.25 mm/day.
Control radiographic and ultrasound examinations of the osteotomy area were made at 10-15 and 40-45 days of distraction,
in 1.5 and 3 months of fixation period.
The radiographs were analyzed to assess visualization of the bone regenerate (density,
structure,
nature of growth,
cortex layer development,
etc.).
Ultrasound examination was performed with linear transducer,
7.5-10.0 MHz.
We used the following procedure of examination:
· examination of paraosseal soft tissues of the treated limb;
· examination of distraction bone regenerate (fig.
2);
· examination of corresponding paraosseal soft tissues and bone of contralateral limb for control image (fig.3)
