Új eljárás körülírt ízfelszín defektusok, valamint proliferatív synovitis gyógykezelésére mozaikplasztika valamint radiosynoviectomia segítségével lovon = Novel technique to treat circumscribed joint surface lesions and proliferative synovitis with Mosaicplasty and radiosynoviectomy in the horse.

1. Klinikai beteganyagon vegzett munka 11 lovon (1-12 ev), negy kulonboző lokalizacioval sikerult SBCs eseteket osszegyűjteni (femur medialis, ill. lateralis condylusan valamint a csudizuletben). A mozaikplasztikahoz a graftokat a femur medialis trochleajanak abaxialis felszineről vettuk. A graftok implantacioja miniarthrotomiabol vagy artroszkopos kontroll alatt tortent. Eredmenyek: Minden lo mozgasa javult a műtetet kovetően; 8 lo korabbi, vagy magasabb szintű teljesitmenyre volt kepes. Egy lo eseteben negy ev utan tapasztaltunk recidivat. Egy esetben tobb egyuttes problema előfordulasa miatt (med meniscus serules) az allat tenyeszerteket sikerult csak megmenteni. 2. Lo csudizuletbe vegzett kiserletes beultetesek 10 lovon (3-4 eves) ultettunk be 6.5 mm es 8,5 mm atmerőjű 20 mm hosszu autograftokat az elulső vegtag csudizuletebe. A lovak ket ev elteltevel kerultek vegleges elaltatasra. Eredmenyek: a beultetett graftok tokeletesen inkorporalodtak kornyezetukbe, a donor areak eseteben is kongruens felszint tapasztaltunk a vizsgalatok alkalmaval. Az altultetett graftok kozott letrehozott porcfosztott teruletek ket ev utan is csak gyengen voltak rostos porccal fedve. Ez alapjan kijelenthetjuk, hogy lovon is igen fontos a teherviselő izuleti felszin teljes kitoltesere torekedni. A technikai hibabol kisse melyre sullyedt graftok eseteben a porckuszas kulonboző jelensegeit tudtuk megfigyelni. | 1. Study on clinical case log In 11 horses (1-12 years) SBCs were identified in 4 locations: medial and lateral femoral condyle, distal epiphysis of the metacarpus , or metatarsus. Osteochondral autograft transplantation (mosaic arthroplasty) was performed, taking grafts from the abaxial border of the medial femoral trochlea of the unaffected limb. Graft implantation was achieved through a small arthrotomy or by arthroscopy depending on SBC location. Results: All horses improved postoperatively; 8 horses returned to a previous or higher activity level. One horse had recurrence after 4 years of work and soundness. One stallion was used for breeding and light riding because of medial meniscal injuries on the same limb. 2. Implantations into the fetlock joint ? experimental study 10 healthy horses (3-4 years) were involved into this study. Graft, 6.5 mm and 8.5 mm in diameter and 20 mm in length were implanted into the weight bearing surface of the dist. epiphysis of the metacarpus. Horses were humanely destroyed 2 years following the first implantations. Results: Transplanted grafts were fully incorporated into the host bed; the donor areas looked congruent and smooth, without fibrillation. 2-4 mm long cartilage missing fields in-between two transplanted grafts were covered with low quality fibrillating fibrocartilage. Conclusion: even little missing hyaline cartilage on weight bearing surface has to be resurfaced even in equine species.
