The effects of limb lengthening on growth
Journal of Pediatric Orthopaedics, Part B, 2003The purpose of this study was to determine the effects of limb lengthening on the rate of growth of the lengthened limb. The rate of growth of the lengthened and control (contralateral) limb segment were determined radiographically pre- and postoperatively in 19 skeletally immature patients (20 limbs).

Limb lengthening by epiphyseal distraction
International Orthopaedics, 1981Limb lengthening has been obtained using the technique of “epiphyseal separation-distraction”, initially in animal experiments and subsequently in operations on twenty-six human patients. The increase of length obtained ranged from 5–11 cm in the tibia and femur. There was no need for osteotomy, internal osteosynthesis, or bone grafting. The quality of

Lengthening of the Lower Limbs in Achondroplastics
1988Lengthening the lower limbs of short stature patients to increase their height is a surgical procedure we undertake exclusively in cases of dysharmonic hyposomia, the most common of which is achondroplasia. The achondroplastic is a dwarf (mean height in adulthood does not exceed 125–130 centimetres) in whom the limbs are noticeably disproportional to ...

Force feedback in limb lengthening
2010 Annual International Conference of the IEEE Engineering in Medicine and Biology, 2010A new variable-rate distraction system using a motorized distractor driven by feedback from the distraction force was designed. The distractor was mounted on a unilateral fixator and attached to the tibiae of 6 sheep that underwent distraction osteogenesis. The sheep were divided equally into 3 groups.

The principles and technique of limb lengthening
International Orthopaedics, 1981We present the details of our studies of leg lengthening since 1962. The operative technique is outlined and the experiments upon which we have based our method are described. The factors which determine the choice of operation and influence its outcome are discussed, the results of 252 tibial and 58 femoral lengthenings are analysed and our ...

Epiphysiolysis as a Method of Limb Lengthening
Clinical Orthopaedics and Related Research, 1978Epiphysiolysis followed by distraction was performed at the proximal tibial growth plates in 18 young rabbits. Union across the distracted plate occurred in all animals. In 12 rabbits skeletally immature at operation, premature fusion of the separated plate resulted in growth arrest of the operated limb.

A formula for diaphyseal limb lengthening
The Journal of Bone and Joint Surgery. British volume, 1990Calculation of the expected limb length discrepancy at maturity plays an important part in the timing of operations designed to equalise length. Present methods assume similar pre-operative and postoperative rates of bone growth in limbs undergoing diaphysea! lengthening procedures.

Limb Lengthening for Achondroplasia
Journal of Pediatric Orthopaedics, 1989Three adolescent patients underwent limb lengthening for achondroplasia by the DeBastiani technique. Average increase in length was 15.4 cm (37.7%) per limb. Bone formation was excellent, and there were no neurovascular complications or infections. Numerous problems were encountered during treatment, but there were only two residual complications in ...

The Callotasis Method of Limb Lengthening
Clinical Orthopaedics and Related Research, 1989Callotasis is a lengthening technique that involves slow, controlled distraction after subperiosteal-submetaphyseal osteotomy. The technique and its advantages over other methods are described. Results of lengthenings involving 270 operated bone segments (146 femurs and 124 tibias) in 140 patients are reviewed.
