Chronic foot pain cases are often diagnostic and therapeutic challenges. Certainly one of the reasons for the diagnostic challenge is the expensive limited access equipment required to visualize the lesions. From the therapeutic standpoint is the chronic non-healing nature of the lesions and as this research shows often more than one lesion is present. More than 80% of the time lesions of the navicular apparatus are accompanied by lesions of the flexor tendon. The conclusion of this study is that further work may begin to elucidate the cause for the degenerative changes associated with the chronic foot pain.

Magnetic resonance imaging evaluation of 264 horses with foot pain: the podotrochlear apparatus, deep digital flexor tendon and collateral ligaments of the distal interphalangeal joint.

REASONS FOR PERFORMING STUDY: To improve understanding of the interrelationships between injuries of the podotrochlear apparatus and deep digital flexor tendon (DDFT). HYPOTHESES: There is a difference in frequency of different types of lesions at different anatomical sites of the DDFT. Lesions of the collateral sesamoidean ligament (CSL), distal sesamoidean impar ligament (DSIL), distal interphalangeal (DIP) joint and navicular bursa are seen in association with lesions of the navicular bone. METHODS: The magnetic resonance (MR) images of 264 horses with unilateral or bilateral foot pain were analysed and graded. Descriptive statistics were performed to establish the frequency of occurrence of DDFT lesion types at different anatomical levels, and lesions of the CSL, DSIL, navicular bursa, DIP joint and collateral ligaments (CLs) of the DIP joint. A Chi-square test was used to test for a difference in the proportion of navicular bone grades between limbs with and without DDFT lesions at each level, and to compare navicular bone grades for limbs with and without each of DSIL, CSL, navicular bursa or DIP joint lesions. RESULTS: Lesions of the DDFT occurred in 82.6% of limbs, occurring most commonly at the level of the CSL (59.4%) and the navicular bone (59.0%). Core lesions predominated at the level of the proximal phalanx (90.3%), whereas at the level of the CSL and navicular bone core lesions, sagittal splits and dorsal abrasions were most common. There was a positive association between DDFT lesions and navicular bone pathology involving all aspects of the bone. Lesions of the DSIL (38.2% limbs) were more common than those of the CSL (10.5%), but the presence of either was associated with abnormalities of the navicular bone, especially involving the proximal or distal borders and the medulla. CONCLUSIONS AND CLINICAL RELEVANCE: There are close interactions between injuries of the components of the podotrochlear apparatus, the DDFT, the navicular bursa and the DIP joint. Further knowledge about the biomechanical risk factors for injury may have importance for both disease prevention and management.

What would you consider lesions? Is it a lesion if it shows up on an exray or ultrasound or is there other things that get something considered a lesion?

Using our medical dictionary Ellab if gives this definition:
<pathology> Any pathological or traumatic discontinuity of tissue or loss of function of a part.
So lesions are any abnormality of tissue and in its widest since includes functional abnormalities also. Diagnostic imaging helps us find lesions but not all lesions are amenable to imaging.

I'm glad you defined it after the medical dictionary or I still would have had a hard time understanding it.

My horse was just diagnosed with DIP and the recovery to do is stall rest and shockwave every 3 weeks for almost 6-9 months. That is beyond what I can afford. Is there any old time method that ever worked before the shockwave machine?

Welcome Maryann,
Let me help you get started off right. Rather than placing questions about your horse at the bottom of another discussion, you should "Start a New Discussion". There are several advantages to keeping discussions separate: - there is no confusion about which question is being discussed
- it will help keep Horseadvice more organized
- you review the Article and "ALL" the existing discussions
- more folks are likely to see your post and so you will receive quicker and more responses
You will find the "Start New Discussion" button on the parent page to this discussion along with an Article and list of already present discussions on this areas topic. Getting there is easy, for example in this discussion: - Scroll to the top of this frame where you will find a navigation bar.
- Click on the "parent pages" link. The parent page is the page from which this discussion originates
Before posting you should review the article as you will find helpful information. If it does not answer your question and you don't see a related discussion that answers your question you should "Start a New Discussion" with your question. For more on this and other important information see Help & Information on Using This Site ยป Welcome to The Horseman's Advisor. Thanks for helping us stay organized.

PS, Many members prefer not to display there full name in their posts. You can edit this in your profile to display your chosen moniker.
PPS, if after reading the article you have a question be sure to define "DIP" in your post. Usually it means "Distal Interphalangeal" as in the anatomical location and not some disease process.
