Abstract

In a preclinical and a clinical study physeal fractures of cats and dogs were fixated with biodegradable implants. The preclinical part consisted of 4 cats with experimental physeal fractures of the distal femurs and the clinical part of 6 cats and 8 dogs with different physeal fractures. All fractures were fixated with selfreinforced polyglycolic acid (PGA) implants of different sizes. No external support was applied after the fixation. All cats and dogs used their operated legs during the first postoperative week and they could walk without lameness in 6 weeks. The fracture healed without delay or malformations. The retardations of the growth of the physeal regions were considered minimal.

Sammanfattning

Fyseala frakturer hos 10 katter och 8 hundar fixerades med resorberbara implantat av polyglykolsyra (Biofix). Fixationerna gav en tilräcklig stabilitet för att frakturerna skulle läka inom tre veckor, utan yttre stödförband. I en preklinisk undersökning framgick att tre till fyra veckor efter fixationerna brast implantaten p. g. a. tillväxtkraften i benet. De uppkomna spalterna mellan implantatets ändar fylldes med regenererande broskvävnad och inte med överbryggande benvävnad. Sålunda inverkade inte fixationen av växtzonerna nämnvärt på benets tillväxt.

Ingen felaktig utveckling av det växande benet, infektioner eller andra patologiska reaktioner kunde påvisas i detta kliniska materiel.
