of propulsion of the body onward.’
The effect of these several obtuse-angled joints in the limb is to absorb the greater part of the force exerted by the body-weight before it reaches the foot. When with this we take the facts that the fore-limbs have to carry the head and neck, and that they have to bear this added weight, plus a propelling force from behind, we see why it is that they should be so subject to the disease, and the hind-limbs so exempt.
As pointing out the part that concussion plays in its causation, we may mention that navicular disease is a disease of the middle-aged and the worked animal. It is interesting to note, too, that it occurs in animals with well developed frogs–in feet in which frog-pressure with the ground is most marked. This at first sight appears to flatly contradict what we have said with regard to frog-pressure in other portions of this work. With this, however, must be reckoned other predisposing causes. In this case it is not to frog-pressure alone we must look, but to the condition of the frog itself, and that of the neighbouring parts. It is when we have a frog which, though well developed and apparently satisfying all demands as to size and build, is at the same time composed of a hard, dry, and non-yielding horn that we must look for trouble.
The foot predisposed to navicular disease is the strong, round, short-toed or clubby foot, open at the heels, with a sound frog jutting prominently out between them. Here is a frog exposed to all the pressure that might be desired for it, bounded at its sides by heels thick and strong, and indisposed to yield, and itself liable, from its very exposure, to become, in the warm stable, hard and dry, and incompressible’ (Percival).
Here, instead of acting, as normally it should, as a resilient body, and an aid to the absorption of concussion, it seems rather to play the part of a foreign body, and to bring concussion about. Seeing, then, that the navicular bursa is in very near contact with it, it is conceivable that this joint-like apparatus should suffer, and the pedal articulation be left unaffected, the more so when we take into consideration the compression theory just described.
4. _A Weak Navicular Bone_.–When the disease commences first in the bone–and there is no denying the fact that sometimes, although not invariably, it does–it may be explained by attributing to the structure of the bone an abnormal weakness in build.
The navicular bone consists normally of compact and cancellated tissue arranged in certain proportions, the compact tissue without, and the cancellated within. These proportions can only be judged of by the examinations of sections of the bone, and when it is found in any case that the cancellated tissue bulks more largely in the formation of the bone than normally it should, we have what we may term a weak navicular bone. In this connection Colonel Smith says: ‘Though it is far from present in every case of the disease, still I consider it a factor of great importance.’
5. _A Defective or Irregular Blood-supply to the Bone_.–This, Colonel Smith considers, is brought about by excessive and irregular work, and by the opposite condition–rest. The author points out that the bloodvessels passing to and from the navicular bone run in the substance of the interosseous ligaments, or in such proximity to them that it is conceivable that under certain circumstances mechanical interference may occur to the navicular circulation. He further points out a fact that is, of course, well known to every veterinarian, that in periods of work the circulation of the foot is hurried, and that in rest there is always a tendency to congestion; and he says in conclusion: ‘I cannot help thinking that irregularities in the blood-supply in a naturally weak bone must be a factor of some importance, especially when the kind of work the horse is performing is a series of vigorous efforts followed by rest.’
6. _Senile Decay_.–With approaching age the various tissues lose their vigour, and are prone to disease. The navicular bone and surrounding structures are not exempt. With the other and more active causes we have described acting at the same time it is not surprising that navicular disease is seen as a result.
In conclusion, it is well, perhaps, to say that, no matter to which particular theory of causation we may lean, we should make up our minds to consider them as a whole. While one cause may be exciting, the other may be predisposing, and the two must act together before evil results are noticed. It may be that even more than two are concerned in bringing on the disease, and to each the careful veterinarian will give due consideration.
_Symptoms and Diagnosis_.–In the early stages of navicular disease the symptoms are obscure. Pointing of the affected limb is the first evidence the animal gives. This, however, more often than not, goes unnoticed, and the first symptom usually observed by the owner or attendant is the lameness. Even this is such as to at first occasion no alarm, being intermittent and slight, and only very gradually becoming marked. In a few cases, however, lameness will come on suddenly, and is excessive from the commencement. It is the lameness, slow in its onset, intermittent in its character, and gradual in its progress, however, that is ordinarily characteristic of navicular disease.
The animal is taken out from the stable sound, with just a vague suspicion, perhaps, that he moved a bit stiffly. While out he is thought by his driver or rider to be going feelingly with one foot or with both. Even this is not marked, and the driver has some difficulty in assuring himself whether or no he really observed it, or whether it was but imagination.
On the return home the limb is examined, and nothing abnormal is to be found. The leg is of its normal appearance, and neither heat nor tenderness is to be observed in it or in the foot. On the following day the animal again is sound, and the lameness of the previous day is put down to a slight strain or something equally simple. The patient is then, perhaps, rested for a day or two. When next he is worked he again moves out from the stable sound, but again during the going gives the driver the unpleasant impression that something is amiss; and so the case goes on. One day the owner fears the animal is becoming seriously enough affected to warrant him in calling in his veterinary surgeon; the next he is confidently assuring himself that nothing is wrong.
Perhaps the animal is now rested for a week or two, or even for a month or two, hoping that this will put him sound. Immediately on commencing work, however, the same symptoms as before assert themselves, and the veterinary surgeon is called in.
With a history such as we have given the veterinarian’s suspicions are aroused. He has the animal trotted, and may notice at this stage that there is an inclination to go on the toes, that the lame limb or limbs are not put forward freely, and that progression is stilty and uncertain; it is such, in fact, as to at once suggest the possibility of corns being present.
In some cases there is just the suspicion of a limp with one limb, and this only at intervals during the trot. At one moment the veterinarian is positive that he sees the animal going lame; at another he is just as confident he sees him coming towards him sound.
Nothing is found in the limb–neither heat, tenderness, nor swelling. There is nothing in the gait (either a limited movement of the radius, or a circular sweep with the leg) to indicate shoulder or other lameness, and the veterinary surgeon, by eliminative evidence, is bound to conclude that the trouble is in the foot.
The foot is then examined–pared, percussed, pinched, and in other ways manipulated–but nothing further is forthcoming. In such a case the veterinary surgeon is wise to declare the abortive result of his examination, to hint darkly of his suspicions, and to suggest a second examination at some future date. It may be that two, three, four, or even more, such examinations are necessary before he can justly pronounce a positive verdict.
Later he is enabled to do this by an increase in the severity of the symptoms, and by the changes that take place in the form of the foot. The lameness is now more marked, and the ‘pointing’ in the stable more frequent. With regard to the latter symptom, it has been seriously discussed whether the horse with navicular disease points with the heel elevated or with it pressed to the ground. In either case, of course, the limb is advanced; but while some hold that the phalangeal articulations are flexed and the heel slightly raised, in order to relieve the pressure of the perforans tendon on the affected area, and so obtain ease, there are others who hold that the heel is pressed firmly to the ground in order to deaden the pain. It may be, and most probably is, that both are right; but, in our opinion, there is no doubt whatever that pointing with the heel elevated is by far the most common.
The lameness is now excessive, and is especially noticeable when the animal is put to work on a rough or on a hard ground. Even now, however, heat of the foot or tenderness is so slight as to be out of all proportion to the alteration in gait.
With the case thus far advanced, evidence of pain may be obtained by pressing with the thumb in the hollow of the heel. Evidence of pain may also be obtained by using the farrier’s pincers on the frog. These methods, however, are never wholly satisfactory, as a horse with the soundest of feet will sometimes flinch under these manipulations.
Extreme and forcible flexion of the corono-pedal articulation also sometimes gives evidence of tenderness. In this case the foot is held up, the animal’s metacarpus resting on the operator’s knee, and the toe of the hoof pushed downwards with some degree of force.
The same movement of the joint is given by causing the animal to put full weight upon the diseased limb, a small wedge of wood being first placed under the toe. In this manner the pressure of the perforans tendon upon the bursa is greatly increased, and the animal is caused to show symptoms of distress.
The lameness may also be increased, and diagnosis helped, by paring the heels, so as to leave the frog prominent and take the whole of the body-weight. The same end is also obtained by applying a bar shoe. This was originally pointed out by Brauell, and is quoted by Zundel and by Moeller.
The changes in the form of the hoof may now be noticed. These are largely dependent on the fact that more or less constantly the patient saves the heel. The horn of the walls in this region, and the horn of the frog, is thereby put out of action and induced to atrophy. The hoof gradually assumes a more upright shape, and the heels contract. We thus get a hoof which is visibly narrowed from side to side, with a frog that is atrophied and often thrushy, and with a sole that is abnormally concave, hard, and affected with corns.
When occurring in the hind-feet–a condition that is rare, but which has been noticed by Loiset, and quoted by Zundel–the animal is stiff behind, walks on his toes, and gives one the impression that he is suffering from some affection in the region of the loins.
One such case is reported by an English veterinary surgeon, and we quote it here:
‘A gray gelding, and a capital hunter, the property of a gentleman in this neighbourhood, became lame in the near fore-foot after the hunting season of 1859. The lameness was believed to be due to navicular disease. The operation of neurectomy was ultimately had recourse to. The horse subsequently did his work as well as ever, and was ridden to hounds regularly till the end of the year 1861, when he went lame of the off fore-foot. From this date he also showed very peculiar action behind, and was at times lame of both hind-limbs without any apparent cause.
‘In the year 1862, from the groom’s indiscreet use of physic, superpurgation was brought on which caused the animal’s death. On a post-mortem examination being made, the horse was found to have _navicular disease of all four feet_. It is worthy of note that this horse had always “extravagant” action behind, but was a remarkably quick and good jumper.'[A]
[Footnote A: F. Blakeway, M.R.C.V.S., _Veterinarian_, vol. ii., p. 21.]
_Differential Diagnosis_.–Navicular disease may be mistaken for ordinary contracted foot. It will be remembered, however, that in the early stages of navicular disease contraction is absent, and that it is only when the disease in the bursa is of long standing that contraction comes on. With ordinary contracted foot, too, careful paring and suitable shoeing soon sees a diminution in the degree of lameness, and a return to the normal in shape (see Treatment of Contracted Foot, p. 125). With navicular disease, however, such shoeing as is beneficial in the treatment of contracted foot (notably the various methods of giving to the frog counter-pressure with ground) soon brings on an aggravation of the lameness.
It is, perhaps, even more likely to be confounded with contraction when we have with the contraction a state of atrophy and thrush of the frog. With a frog in this condition pressure will give rise to pain, and navicular disease be erroneously judged to be present. In such a case we must rely wholly upon either extreme flexion or extreme extension of the joint to guide us, when, if contraction _only_ is the offending condition, no symptom of pain will be shown.
Navicular disease may also be confused with rheumatic affections, with sprain of the posterior ligaments of the first interphalangeal articulation, and with sesamoid lameness. Mistakes are sometimes made, too, especially with a hasty observer, in confounding it with shoulder lameness.
In rheumatism the constant changing of the seat of pain, the sometimes elevated temperature, and the appearance of symptoms of heat, tenderness, and swelling in the affected area should guide one to a right conclusion.
In sprain of the posterior ligaments of the coronet and in sesamoid lameness, nothing but a careful examination and manipulation of the parts will ward off error, for in each of these cases there is ‘pointing’ and resting of the limb, and considerable disinclination to put weight firmly upon it. If at the same time manipulation gives distinct evidence of pain, all doubt may be set at rest.
Roughly speaking, sesamoid lameness is a condition of the gliding surface of the sesamoids, and the face of the tendon playing over them, similar to that found in navicular disease. All symptoms of pointing, the constant maintaining of the limb in a state of flexion, and a feeling manner of progression are again all present. It is plain from this that in all cases where an animal with a gait at all suggestive of navicular disease is brought for our examination, the manipulation of the limb should be thorough. The character of the lameness is almost sure to deceive us; and it is not until we are able to obtain local symptoms pointing to the one or the other of the conditions we have enumerated that a decisive opinion may be given. In sesamoid lameness the local symptoms are those of heat and pain in the fetlock on palpation, and a swelling of the affected parts, such swelling being at first slight, yielding, and barely distinguishable, and afterwards larger, bony and hard, and more marked. Later still there is distinct evidence of ‘knuckling’ over at the fetlock and inability to fully flex it.
In cases of shoulder lameness the gait alone should be sufficient to render liability of error small, for with nearly every case there is a manifest inability to ‘get the limb forward’, and this is best seen at a side view when the animal is trotting past the observer. When trotting towards one, there is a further and unmistakable symptom common to most shoulder lamenesses that serves to distinguish it at once, and that is the peculiar ‘sweeping’ outwards with the affected limb.
Lastly, with either of the conditions we have just mentioned, it is the exception to get contracted foot follow on. With navicular disease it sooner or later makes its appearance.
_Prognosis_.–The prognosis of navicular disease (once diagnosed with certainty) must almost of necessity be unfavourable. The facts that the disease has made serious progress before it is really noticeable, that the situation of the parts prohibits operative interference, and that the disease is one of a chronic and slowly progressive type, all point to an unfavourable termination.
_Treatment_.–We have seen from the pathology of this disease that it may commence either as a rarefactive ostitis, or as a synovitis and tenositis in connection with the bursa. With the former condition in existence, or when this and the synovitis has led to erosion of the cartilage, treatment is probably of no avail, on account of the more chronic nature of these two conditions. When, however, the condition is simply that of synovitis or tenositis, a more or less acute condition, we may assume that suitable treatment and a long rest will bring about resolution.
The first indications in treatment are those of what we may term ‘nursing’ the foot. It should have sufficient rest, should be placed so as to minimize as far as possible compression of the parts, and should have its posterior half treated so as to render it softer and less liable to concussion.
The period of rest required cannot be satisfactorily advised, and the practitioner is wise who makes it a long one. Best should be advised, in fact, long after symptoms of lameness have disappeared and recovery is judged to have taken place.
Compression of the parts may be somewhat minimized, if the animal be kept in the stable, by allowing the floor upon which the front-feet are to stand to be slightly sloping from behind forwards. The same effect, though not so marked, is obtained by removing the shoes, and considerably lowering the wall at the toe, while allowing that of the heels to remain. It may here be remarked that it is a good practice to allow the shoes to remain on, and this even when the animal is at grass. They should, however, be frequently removed, and the foot trimmed as we have directed.
With the foot thus trimmed so as to most suitably adjust the angles of the articulations, it should next be thoroughly pared and rasped in its posterior half, so as to render the horn of the sole and the frog and the horn of the quarters as thin as possible. The heels, however, should not be excessively lowered, _if at all_. We now have the foot in a soft condition, and easily expanded. It should, if possible, be kept so; and this may be done either by the use of poultices, by tepid baths, or by standing the animal upon a bedding that may easily be kept constantly damp. Such materials as tan, peat moss, or sawdust, are either of them suitable.
All this, of course, calls for keeping the animal in the stable. It is far better, however, more especially if a piece of marshy land is at hand, to turn him out in that. A moderate amount of exercise is beneficial rather than not, and the feet are thus constantly kept damp without trouble to the attendants.
The second indication in the treatment is that of applying a counter-irritant as near to the diseased parts as possible. Regarding its efficacy we must confess to being somewhat sceptical. The treatment has been constantly practised and advised, however, and we feel bound to give it mention here. A smart blister may, therefore, be applied to the whole of the coronet, and need not be prevented from running into the hollow of the heel.
Instead of blistering the coronet (or in conjunction with that treatment), the counter-irritant may be applied by passing a seton through the plantar cushion or fibro-fatty frog. Setoning the frog appears to have been introduced by Sewell. In many cases great benefit is claimed to have been derived from it, especially by English veterinarians of Sewell’s time, and by others on the Continent. Percival, however, was not an advocate for it, and, at the present day, it is a practice which appears to have dropped out of use altogether.
[Illustration: FIG. 164.–FROG SETON NEEDLE.]
To perform this operation a seton needle of a curved pattern is needed (see Fig. 164). This is threaded with a piece of stout tape dressed with a cantharides, hellebore, or other blistering ointment, and then passed in at the hollow of the heel, emerging at the point of the frog. The course the needle should take will be understood from a reference to Fig. 165.
The seton may be passed with the horse in the standing position. Previously the point of the frog should be thinned, and the animal should be twitched. After-treatment consists simply in moving the seton daily, and dressing it occasionally with any stimulating ointment, or with turpentine.
If, in spite of these treatments, the disease persists, then nothing remains but neurectomy.
D. DISLOCATIONS.
The firm and rigid manner in which the bones of the pedal articulation are held together renders dislocation of this joint an exceedingly rare occurrence, and then it is only liable to happen under the operation of great force. In the literature to our hand we have only been successful in discovering one reported instance, and, strange to say, in this, a well-marked case, the cause was altogether obscure. We quote the case at the end of this section.
[Illustration: FIG. 165.–DIAGRAM SHOWING THE COURSE TAKEN BY THE NEEDLE WHEN SETONING THE FROG. This is shown by the dotted curved line _a, b_. 1, The navicular bone; 2, the plantar cushion; 3, the os pedis; 4, the perforans tendon.]
A partial dislocation of this articulation is the condition met with in ‘Buttress Foot.’ In this case the fracture of the pyramidal process, and the consequent lengthening of the tendon of the extensor pedis, allows the os coronae to occupy upon the articulatory surface of the os pedis a more backward position than normally it should.
It is quite probable, too, that slight lesions of the other restraining ligaments and tendons of the articulation may bring about a similar though less marked condition. We may be quite sure of this–that whenever such lesions (as, for example, sprain and partial rupture of the lateral ligaments) do occur, and the normal position of the opposing bones is changed, if only slightly, that great pain and excessive lameness must be the result, and this with but little to show in the foot. Many of our cases of obscure foot lameness might, if capable of demonstration, turn out to be cases of sprain and partial dislocation of the pedal articulation.
_Recorded Case_.–‘The animal, a trooper of the 8th Hussars, was found on the morning of April 17 unable to bear any weight on the limb (the near hind). Cause not known–the heel-rope I thought at first; but on investigation I found the heel-rope had been on the other leg.
_Diagnosis_.–Dislocation of the left os coronae from the articulating surface of the os pedis in a backward direction.
‘Every devisable means were unsuccessful in reducing the limb to its natural position. The horse was thrown, and a strong rope, with four men pulling at it, was fastened round the hoof, whilst I put my knee to the back of the pastern, using all possible force, with one hand to the foot and the other to the fetlock, but all to no purpose. Next day other means were tried. First by throwing the horse and placing him on his belly, with the fore-legs stretched out forwards, and the hind-legs backwards. This I did so as to get the injured limb placed as nearly flat on the ground as possible, with its anterior aspect downwards. Then a very heavy man, with his boots off, was made to jump on the back of the pastern, where the prominence showed most; and afterwards, when these means failed, a strong piece of wood, well covered with leather, was placed (where the hollow of the heel ought to have been) on the most prominent part, and hit several times with a heavy hammer; but all efforts were futile.
‘_Prognosis_.–Unfavourable. During the latter operations I had a very strong pressure applied to the hoof, and the horse firmly fastened in every way, and it appeared as though no amount of force would ever reduce the dislocation.
‘_Tautological_.–The case was destroyed on April 30, being of no further use to the service.
‘_Post-mortem_.–The os coronae was found to have slipped out of the articulating cavity of the os pedis, backwards and past the lateral ligaments. These last-named structures prevented the bone being forced forward into its proper position, being firmly locked over the lateral prominences. The capsular ligament was considerably lacerated and inflamed, causing slight effusion and swelling about the region of the coronet.'[A]
[Footnote A: T. Flintoff, A.V.D., _Veterinary Journal_, vol. xix., p. 74.]
_Treatment_.–After the forcible means of reduction related by Mr. Flintoff, we may add that when they are successful, they should be followed by suitable bandaging of the parts, and rest. The first is effected by applying plaster of Paris and linen, and the second by having the animal put in slings.
