Bone Growth Alterations Resulting from Application of Co₂Laser Beam to the Epiphyseal Growth Plates:An Experimental Study in Rabbits

Electrical stimulation of the growth plate: A potential approach to an epiphysiodesis

“…While there is a consistent decrease in allthe zones ofthe growth plate dimensionsas a result of 50 mA, performing an ANOVAwith a limited sample size (n ¼ 4) was not sufficient to achieve statistical significance. [Morein et al, 1978;Rosen et al, 1990]. In this study, our histology was consistent with the findings of shrinkage of the growth plate with distinct morphological changes such as local clusters of chondrocytes and loss of columnar arrangement, which were similar to findings in epiphyseal stapling [Karbowski et al, 1989].…”

“…Forgon et al [1985] also reported the stimulation of growth with an electrical current of 20 mA. A number of different approaches have been used to achieve an epiphysiodesis, including electrocautery [Rosen et al, 1990] or lasers [Morein et al, 1978] to destroy cells of the growth plate. In our study, we show evidence of growth retardation or partial epiphysiodesis using a level of electrical current of 50 mA applied directly to the epiphyseal plate.…”

Percutaneous Radiofrequency Epiphysiodesis in a Rabbit Model: A Pilot Study

“…However, many of these patients will have a second surgical procedure for removal of implants at the end of skeletal growth. Several other alternative techniques for achieving controlled physeal arrest have been proposed, including the use of laser destruction of the growth plate in a rabbit model [10] and thermal destruction of the growth plate in rabbit and dog models using standard electrocautery [16].…”

The Influence of Shock Waves on Epiphysial Growth Plates: First Results of an In-Vivo Study with Rabbits

“…arteriovenous shunts [14], venous stasis [14], interruption of epi-or metaphysial blood supply [31], sympathectomy [2,10], obstruction of the medullary artery [6,16], resection of the periosteum [16,23,29], percutaneous curettage [5] or forage [8,22], CO2 laser [21], electrocauterization [26], X-rays [18,24], heat [25], cold [4], ultrasound [9], implantation of various materials [23,34], electricity and electromagnetic fields [3,33]. In individual cases, satisfactory results were achieved.…”
