The veterinary surgeon Gaspar Castelijns together with the farrier Ricardo Rosello pioneered a shoeing system which addresses the aims mentioned before very effectively.
After trimming the dorsal hoof wall parallel to PIII and at an appropriate thickness and establishing a close to normal palmar angle by trimming back the heels, a Dallmer Cuff is glued on the previously cleaned and dried remaining hoof wall with fast setting polyurethane’s or acrylics. On the bottom of the cuff a full rolling motion like shoe (e.g. Equi+ or Rockn’Roll) is screwed on, holding a palmar support in place of fast setting oral impression material (condensation silicone) which offers anatomical palmar support to the foot. (Fig.7)
By forging down the front part of the shoe and by screwing it on further back, dorsal break over is moved caudally (less DDFT pull). (Fig.8)
Because of the rolling motion shoe type design, not only dorsal but also latero medial break over is facilitated, which makes turning, with its asymmetrical tensions on the hoof capsule - PIII bond, much less pain full for the patient. (Fig. 9)
The 7 mm thickness of the bottom of the glue on cuff gives welcome and extra sole depth, prolapsed soles can be inspected and treated with disinfectants by simply unscrewing the full rolling motion shoe which trough its closed design offers full protection to the sole. The cuff can be opened at the toe, to gain access to dorsal wall or sole cavities and is compatible with subcoronary grooving. (Fig. 10) - (Fig. 11)
The gluing on is atraumatic and with the use of Superfast (winter) or Adhere (summer) so fast that it can almost always be done without regional anaesthesia of the opposite limb (do the most pain full limb first, place the other on a block of Styrofoam).
Once healthier hoof wall has grown down, at least at the heels, and a good sole depth has been obtained the Rockn’Roll can be nailed on the hoof directly, always in combination with condensation silicone as palmar support. This same method is very effective in mild cases of founder or at the beginning of laminitis. (Fig. 12)
There are some extreme cases where sloughing of the entire hoof capsule is inevitable, facilitating the removal of the detached hoof capsule seems to bring relieve but nothing to nail or glue on to! Deep bedding, good bandaging and nursing can tie these patients over till they have grown a new hoof capsule back, a process which goes much quicker then one would expect. (Fig.13) - (Fig.14)
The real unretrievable loss in founder cases is bone loss from PIII, the hoof capsule grows back as long as the coronary band is relieved from mechanical pressure, by the upwardly displaced hoof capsule and is not damaged by compressive bandaging or casting.
