Abstract

The purpose of this report is to describe the technique and the clinical outcome of three dogs affected by superficial digital flexor (SDF) tendon luxation treated using a calcaneal chondroplastic-like technique. A German Pinscher with bilateral and lateral SDF tendon luxation, a Griffon Nivernais with medial SDF tendon luxation following self-mutilation of the IV toe, and an American Staffordshire Terrier with a lateral luxation and having undergone calcaneal chondroplasty and primary repair of the retinacular tissues. A fibrocartilage flap covering the calcaneal groove was elevated, the subchondral bone was removed from beneath it, and the flap was pressed back into the deepened sulcus, keeping its distal attachment as a hinge point. The SDF tendon was reduced, and its tracking along the deepened groove was ensured. Furthermore, the torn retinacular attachment was repaired. Clinical follow-ups at 4 and 8 weeks and 1 year apart showed no signs of lameness and no SDF tendon re-luxation. The calcaneal chondroplastic-like technique led to a satisfactory outcome with no complications. This technique is relatively straightforward, requires no implants, and is also successful without postoperative immobilization of the tarsal joint. Further cases are required to determine its benefits and its risks compared to conventional surgery.
