The response to perineural analgesia of the palmar digital nerves and palmar (abaxial sesamoid) nerves, intra\u2010articular analgesia of the distal interphalangeal (DIP) joint and analgesia of the navicularbursa were reviewed. The result of ultrasonography of the pastern and foot was recorded. Lateral, dorsal and solar pool and bone phase nuclear scintigraphic images were assessed subjectively and objectively using region of interest (ROI) analysis.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:italic>Results<\/jats:italic>\n                    : Forty\u2010six (61%) of 75 horses examined using MRI had lesions of the DDFT considered to be a major contributor to lameness. Thirty\u2010two horses (43%) had primary DDFT injuries and 14 (19%) a combination of DDF tendonitis and navicular bone pathology. Lesions involved the insertional region of the tendon alone (n = 3), were proximal to the navicular bone (n = 23) or were at a combination of sites (n = 20). Lesion types included core lesions, focal and diffuse dorsal border lesions, sagittal plane splits, insertional injuries and lesions combined with other soft tissue injuries. Many horses had a combination of lesion types.\n                  <\/jats:p>\n                  <jats:p>\n                    Lameness was abolished by palmar digital analgesia in only 11 of 46 horses (24%). Twenty\u2010one of 31 horses (68%) in\n                    <jats:italic>Group I<\/jats:italic>\n                    showed &gt;50% improvement in lameness afterintra\u2010articular analgesia of the DIP joint, whereas 11 of 12 horses (92%) in\n                    <jats:italic>Group II<\/jats:italic>\n                    had a positive response. Twelve of 18 horses (67%) in\n                    <jats:italic>Group I<\/jats:italic>\n                    had a positive response to analgesia of the navicular bursa.\n                  <\/jats:p>\n                  <jats:p>Nineteen horses had lesions of the DDFT extending proximal to the proximal interphalangeal joint seen using MRI, but these were identified ultrasonographically in only 2 horses. Scintigraphic abnormalities suggestive of DDFT injury were seen in 16 of 41 horses (41%), 8 in pool phase images and 8 in bone phase images. Conclusions and potential relevance: DDFT injuries are an important cause of lameness associated with pain arising from the digit in horses without detectable radiographic abnormalities. Lameness is not reliably improved by palmar digital analgesia, but may be improved by intra\u2010articular analgesia of the DIP joint in at least 68% of horses. Ultrasonography is not sensitive in detecting lesions of the DDFT in the distal pastern region, but a combination of pool and bone phase scintigraphic images of the digit is helpful in some horses. Further follow\u2010up information is required to determine the prognosis for horses with lesions of the DDFT in the digit and to establish whether this is related to lesion severity and\/or location.<\/jats:p>","DOI":"10.2746\/042516403775696294","type":"journal-article","created":{"date-parts":[[2007,4,12]],"date-time":"2007-04-12T19:03:27Z","timestamp":1176404607000},"page":"681-690","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":101,"title":["Lameness in 46 horses associated with deep digital flexor tendonitis in the digit: diagnosis confirmed with magnetic resonance imaging"],"prefix":"10.1111","volume":"35","author":[{"given":"S.","family":"Dyson","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"R.","family":"Murray","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M.","family":"Schramme","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M.","family":"Branch","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2010,1,5]]},"reference":[{"key":"e_1_2_1_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/B978-0-7216-8342-3.50017-6"},{"key":"e_1_2_1_3_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.2042-3306.1994.tb04372.x"},{"key":"e_1_2_1_4_1","doi-asserted-by":"publisher","DOI":"10.2460\/ajvr.2001.62.414"},{"key":"e_1_2_1_5_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1740-8261.2001.tb00983.x"},{"key":"e_1_2_1_6_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1740-8261.2002.tb01029.x"},{"key":"e_1_2_1_7_1","doi-asserted-by":"publisher","DOI":"10.1002\/9780470690390.ch2"},{"key":"e_1_2_1_8_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1740-8261.1992.tb00135.x"},{"key":"e_1_2_1_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0749-0739(17)30358-9"},{"key":"e_1_2_1_10_1","unstructured":"Denoix J.\u2010M.(1999)Ligament injuries of the distal interphalangeal joint in horses.
