Re: Underwater Treadmill Questions

We have two Fernos and have had a lot of trouble with them (one yr

old). Especially the fancier model I think it is called the AquaPaws Plus. I

will admit I am not the person who deals with them (either the treadmills or

the reps or repair people) for the most part so you must take my opinion

with a grain of salt. All I know is they seem to break a lot, get stuck and

won't drain properly, make clunking sounds. And it seems to take a lot of

effort to get the help we need. Also my principal dislike with these

treadmills is they only open at one end so you have to turn the dog around

in them and if you have a big dog with serious mobility issues this is

difficult. Also the nominal " front " is solid and the dogs don't like walking

towards the solid partition so we always turn the dog around and run the

tread in reverse so they can walk towards the glass door and see their

owners. The other Ferno we have, which inclines (but it is hard to change it

from inclined to flat so we usually just leave it inclined) is worse, as it

has a solid front and one solid side (the newer model has three sides glass

one side solid) and many dogs will not walk in it as they seem to feel to

closed in. This one does not run in reverse or at least not easily. I have

not done treadmill shopping so I am not familiar with what else is out there

but if you can get one with doors at both ends and all glass and even one

where you can get it to incline by pushing a button rather than manhandling

the treadmill then I personally would prefer that.

We are looking at adding a UWTM and have seen the Ferno product and the

Hydro Physio. However, I see more Ferno units but hear stories about their

service. My question is, what does that mean? Do they stand behind their

warranty? The area I am in has a service company for when the warranty runs

out. So, who are the complaints with? Ferno or the service companies?

I also was told that Hydro Physio recently sold a uwtm as a demo unit.

Rumored it was previously sold to a clinic and taken out due to quality

issues. This same uwtm was sold again to another clinic and the same issues

happened. Also told that clinic is suing Hydro over not being truthful about

the unit.

Anyone know the truth?

2a. Shepherd with elbow " click "

Posted by: " Hillside Vet Hospital " doctors@...

Date: Fri Oct 29, 2010 1:50 pm ((PDT))

I recently examined a new patient, a 4 year old male German Shepherd, for

evaluation of a subtle R foreleg lameness which the owner feels has been

present for a couple of years on & off and which seems worse after heavy

exercise, particularly when he has been " rough housing " with her other dog.

This dog is lean but big (43 kg) and is used for herding and bomb detection.

He has never been evaluated by a veterinarian for this problem. We could

not detect any lameness, so we did a gait analysis (corn starch test) which

confirmed a slightly shortened stride on the R fore. I couldn't feel any

abnormalities or elicit any kind of a pain response on examination of the R

foreleg. There was normal ROM of all joints however he did have a

repeatable audible " click " at end extension of the R elbow. I can feel a

ropey structure (medial collateral ligament?) on the medial aspect of the

elbow joint whose movement seems to coincide with this click.

His elbows were x-rayed and sent to a radiologist for interpretation and the

report came back as " subtle and minimal degenerative changes in both elbows,

probably not severe enough to account for clinical signs " . (This dog also

had his elbows evaluated by the OFA at 2 years of age and they were found to

be clean).

I have tried to research this " click " as the owner is curious and would like

a diagnosis, but have not had much luck. Has anyone else ever come across

this and, if so, are you able to clarify for me what is likely happening and

what we should do about it? I realize that the lameness may be unrelated.

Thanks to anyone who can shed some light on this for me!

Sylvie,

This sounds like classic " jump down syndrome " or traumatic fragmented medial

coronoid process....acute lameness, clean radiographs, medial compartment

sensitivity, and intermittent click.....I would scope the elbow asap before

it causes secondary cartilage erosion...bit more information below:

Traumatic Fragmented Medial Coronoid Process

Traumatic fragmented medial coronoid process (TFMCP) is a condition in the

elbow joint of dogs that appears to occur commonly in performance and

working dogs. Unlike the classic condition of fragmented medial coronoid

process (FMCP) affecting the elbow joints of skeletally immature large to

giant breed dogs, jump down syndrome (TFMCP) appears to have no age or size

limitations.

Cause

The cause and pathogenesis of TFMCP are poorly understood. It is possible

that abnormal repetitive loading, such as landing from a jump, hitting

contacts or a flyball box, and so on, may lead to microfractures of the bone

underneath the cartilage (subchondral fractures). Additionally, increased

repetitive loading can arise from contraction of the biceps/ brachialis

muscle complex. When the biceps/brachialis contracts, a force is generated

that rotates the medial coronoid into the radius. These microcracks disturb

the mechanical properties of bone, and if not repaired properly through

normal body mechanisms, fatigue fractures develop. Additionally, loss of

osteocytes (bone cells), indicated by decreased osteocyte densities, has

been strongly associated with the presence of microdamage after fatigue

loading. These studies imply that excess load may lead to fatigue

microdamage of the subchondral trabecular bone and eventual fracture, which

we believe may play an important role in the pathogenesis of TFMCP. Dogs may

be further predisposed to this condition if they have elbow dysplasia. Dogs

with elbow dysplasia had asymmetric growth of the radius and ulna during

development, resulting in elbow joint incongruity. Elbow incongruity such as

radioulnar step defects, humeroulnar incongruence/conflict, and varus

deformity of the humerus causes abnormal contact patterns in the elbow,

specifically at the coronoid trochlear articulation, which is theorized to

increase the load on the medial coronoid process (MCP). Regardless of the

etiology, if left untreated as a continual lameness, secondary

osteoarthritis may progress as noted by damage to the cartilage such as

softening, fibrillation, fissuring, and erosions as well as additional

subchondral bone microcracks and fragmentation. The free fragments

contribute to frictional abrasion ( " kissing lesions " ) of the opposing

surface including the medial aspect of the humeral condyle and radial head.

Diagnosis

History and Clinical Signs

Dogs with TFMCP may present with a history ranging from a subtle

intermittent offloading of the forelimb to significant unilateral or

bilateral forelimb lameness. This lameness is typically exacerbated with

exercise and heavy activity. The onset of lameness is insidious. As lameness

persists, it may increase in severity. Affected dogs often place the carpus

in an exaggerated valgus position (turned out) when sitting or standing, and

circle the foreleg outward and move the elbow away from the midline

(circumduct the antebrachium and abduct the elbow) during the swing phase of

the stride. The history of dogs with TFMCP typically includes a lack of

response to rest and non-steroidal anti-inflammatory drugs (NSAIDs). Many

dogs with TFMCP are mistakenly treated for shoulder pathology because the

attending veterinarian elicits a pain response when the shoulder is

extended. The authors believe the pain response actually arises from the

elbow because when the veterinarian performs an extension maneuver of the

shoulder, the elbow is usually simultaneously extended. Extension of the

shoulder and elbow causes tension in the biceps/brachialis muscle complex.

Tension in the biceps/brachialis exerts pressure on the medial coronoid and

overlying inflamed joint capsule causing the pain response.

Orthopedic Examination

On physical examination discomfort is usually noted on direct palpation of

the medial compartment of the elbow joint, specifically the medial coronoid

process. Discomfort may also be noted on hyperflexion of the elbow. Most

dogs with TFMCP are reluctant to allow for full endrange flexion. In chronic

cases, full flexion may not be obtained. Crepitus may be noted when placing

the elbow through range of motion. Some investigators suggest that the

carpus should be placed in a flexed, externally rotated position while the

elbow is extended. Joint effusion may be detected as a fluctuant swelling

beneath the lateral or medial epicondyle of the humerus. Depending on the

chronicity, atrophy may be noted in the affected forelimb.

Advanced Diagnostics

In addition to history, gait analysis, physical examination, orthopedic and

neurologic examinations, further diagnostic tests used to differentiate

causes of elbow pathology currently consist of hematology, biochemical

profile, urinalysis, arthrocentesis, imaging modalities, and arthroscopy.

Unfortunately, radiographs have been shown to be of little value because of

difficulty identifying the fragment or line of separation using standard

radiography. In some chronic cases, however, radiographs may reveal

secondary evidence of bony remodeling consistent with osteoarthritis. These

changes may include sclerosis within the ulnar notch, and remodeling along

the anconeal process and MCP. Advanced diagnostic imaging modalities such

as CT scans, MRI, nuclear scans, and arthroscopy may allow confirmation of

the condition. Arthroscopic evaluation of the elbow joint allows direct

observation of all major intra-articular structures with magnification,

" dynamic " evaluation of tissues during elbow range-of-motion tests, and

" palpation " of intra-articular tissues using arthroscopic instrumentation.

Arthroscopic exploration of the elbow provides a definitive diagnosis of

TFMCP when a fragment or cartilage fissure. In a small percentage of cases,

advanced imaging (nuclear scan, CT, MRI) indicates fragmentation of the

coronoid but arthroscopic observation does not reveal a fissure or fragment.

In such cases, the fissures (microcracks) are believed to be within the

coronoid bone beneath the cartilage surface.

Treatment

Treatment of TFMCP is multimodal and includes a combination of medical and

surgical management as well as rehabilitation therapy. Through a multimodal

approach it is possible to relieve pain and maintain limb function, as well

as to return the dog to a normal level of activity and competition.

Arthroscopy is an excellent modality for diagnosing TFMCP as well as a

minimally invasive means of treatment. Arthroscopic removal of the fragments

is recommended not only to remove the inciting cause of lameness but also to

help prevent/slow the progression of osteoarthritis. Arthroscopic treatment

may include a combination of techniques such as fragment removal,

debridement of diseased tissues, creation of vascular access by abrasion

arthroplasty, forage, microfracture, and subtotal coronoid ostectomy

depending on the progression and severity of disease. Arthroscopy is not

only a great diagnostic modality, allowing for superior visualization of

structures within the joint, but also has less soft tissue trauma, shorter

surgery and hospitalization times, decreased risk of infection, and shorter

recovery times compared to the traditional surgical approach of fully

opening the joint (arthrotomy).

Following arthroscopic treatment, dogs are typically prescribed NSAIDs for

14 days to help decrease inflammation and discomfort. Polysulfated

glycosaminoglycans (PSGAG) an injectible joint protective agent, is also

recommended following arthroscopic treatment and is administered

intramuscularly twice a week for up to four weeks. PSGAGs has been shown to

decrease the amount of degradative enzymes (that stimulate inflammation and

cartilage erosion) as well as promote repair and regeneration of cartilage.

In addition, an oral joint protective agent such as glucosamine, chondroitin

sulfate, and avocado/soybean unsaponifiables (ASU), is recommended as a

daily supplement for life. The anti-inflammatory properties and

pain-reducing effects of these supplements have been well-documented.

There is also evidence that they may have a cartilageprotective effect.

As with any rehabilitation therapy program, elbow rehabilitation following

elbow arthroscopy should follow a sequential and progressive multiphased

approach. The ultimate goal of elbow rehabilitation is to return the

patient to their previous functional level as quickly and safely as

possible. However, each case is uniquely different, and several factors;

including duration of injury/lameness prior to surgery, secondary

osteoarthritc conditions, surgical intervention performed, all influence

the rate at which the patient proceeds through the healing process.

The elbow is predisposed to flexion contractures due to the intimate

congruency of the joint articulations, the tightness of the joint capsule,

and the tendency of the anterior capsule to develop adhesions following

injury. The biceps/brachialis complex also attaches to the capsule and

crosses the elbow joint before becoming a tendinous structure and inserting

on the ulnar tuberosity. Injury to the elbow may cause excessive scar

tissue formation of the brachialis muscle as well as functional splinting of

the elbow. Reestablishing full elbow extension is the primary goal of early

ROM activities to minimize the occurrence of elbow flexion contractures.

Additional goals of this stage are to protect healing tissue, decrease pain

and inflammation, restore weight bearing and retard muscular atrophy. The

rehabilitation therapist must not overstress healing tissues during this

phase. It is important that the owner restrict the dog's activity to short

leash walking only with no running, jumping and rough play.

Hope this helps.......please let me know if you need help finding a surgeon

in your area that scopes....

Happy Halloween!!!
