Surgical correction of short stature
The aim of surgical orthopaedics in short stature is to increase overall height and improve body proportions. It is particularly applicable to lower limb lengthening in achondroplasia, hypochondroplasia, Turner's syndrome and Ellis-van Creveld syndrome. Two methods are routinely used in Verona: chondrodiatasis and callotasis. Although simultaneous lengthening of tibia and femur of the same limb have generally been employed, recent efforts have concentrated on simultaneous lengthening of one femur and the contralateral tibia. Lengthening of up to 20-25 cm can now be achieved, with a complication rate below 20%
Epiphyseal distraction. Hemichondrodiatasis.
Hemichondrodiatasis is a technique of closed, gradual, asymmetric distraction of the growth plate to correct angular deformities in growing children. This report describes the technique and the results achieved in 35 operated lower extremity segments, 14 involving the femur and 21 involving the tibia. The best results were achieved in posttraumatic deformities when the bone bridge occupied less than 20%-30% of the epiphyseal plate. The procedure is best performed toward the end of growth, or earlier if a progressive deformity exceeds 15 degrees - 20 degrees
The correction of axial limb deviations during growth by controlled asymmetric distraction of the growth plate (Hemichondrodiatasis).
Epiphyseal distraction. Chondrodiatasis.
Chondrodiatasis is a limb-lengthening technique involving slow, controlled, symmetric epiphyseal distraction. The clinical and histological differences between this technique and distraction epiphysiolysis are described. Results are given for the elongation of 170 bone segments in 75 children (41 with limb-length discrepancies and 34 with achondroplasia). All patients were operated upon while the growth plate was still open with maximum bone maturation corresponding to Risser 2
Controlled symmetrical distraction of the growth plate (chondrodiatasis) to achieve limb lengthening in children.
Articulated distraction of the hip. Conservative surgery for arthritis in young patients
Between 1979 and 1982, 80 patients with a variety of hip diseases were treated with articulated distraction of the hip. The patients ranged from nine to 69 years of age (mean, 34 years). The primary diagnoses were avascular necrosis, osteoarthrosis, and chondrolysis. A standard dynamic axial fixator with a single axis articulating unit was used to create a 5-mm joint space. The fixator allowed flexion and extension motion and remained in place for six to ten weeks. The follow-up period ranged from five to eight years. Assessment was performed by questionnaire, clinical, and radiographic review. The results were poor in 24 patients who were either older than 45 years of age or had a diagnosis of inflammatory arthropathy. Forty-two good results were found in the 59 patients younger than 45 years with osteoarthrosis, hip dysplasia, avascular necrosis, and chondrolysis. Only four patients older than 45 years of age had a good result. No serious complications occurred
