Summary Accurate diagnosis of conditions of the equine proximal metacarpus and metatarsus presents a clinical challenge. Diagnostic analgesia of this region is nonspecific, which may lead to incorrect interpretation of blocking patterns, potentiating incorrect diagnoses and treatment. Results of local analgesia should be examined carefully during clinical lameness evaluations due to the possibility of diffusion of local anaesthetic solution and inadvertent intrasynovial injection. Supplementary diagnostic analgesia of surrounding anatomic regions and advanced diagnostic imaging, particularly magnetic resonance imaging, are recommended for most accurate diagnosis of lameness. Failure in response to therapy in cases where supplementary diagnostic analgesia and advanced diagnostic imaging have not been performed should prompt the clinician to broaden the approach to better characterise the site of pain.

“…As a result, when a horse is presented because of hindlimb proximal suspensory desmitis, the lesions at the origin of the ligament may be chronic and more pronounced than in a horse with similar forelimb lameness. Furthermore lameness attributable to the proximal suspensory ligament in hindlimbs may be exacerbated by pressure damage to the deep branch of the lateral plantar nerve, which runs in close proximity to the proximal suspensory ligament (Toth et al 2008). …”

Summary: Medical records of horses examined from 1994 to 2011 at the Equine Hospital, Vetsuisse Faculty, University of Zurich, because of proximal suspensory desmitis (PSD) were reviewed. Radiographic changes visible on dorsopalmar and dorsoplantar projections of the proximal third metacarpal/metatarsal bone (MCIII/MTIII) were analysed with respect to localisation, degree of increased radiopacity, length, width and pattern of radiopacity in relation to sex, age, breed, duration and degree of lameness and affected limb of the horses. Results were compared with those from sound control horses. Horses with PSD had increased radiopacity, which was significantly more prevalent medially than laterally in the forelimbs (p < 0.05) and more prevalent laterally than medially in the hindlimbs (p < 0.05). The width of the area of increased radiopacity was significantly greater in the forelimbs than in the hindlimbs (p < 0.05). The pattern of increased radiopacity was diffuse in 102 (85.7 %) horses and multifocal in the remaining 17 (14.3 %). 35.3 % (n = 6) of multifocal changes were detected on one of the front limbs, whereas 74.7 % (n =11) were diagnosed on the hind limbs. Mildly increased diffuse radiopacity, with a distribution pattern comparable to cases with PSD was detected in 15 of 60 control horses. In comparison to control cases, the degree of increased diffuse radiopacity was significant more pronounced in horses with PSD (p < 0.001). The multifocal pattern of increased radiopacity could not be detected in any of the control horses. The results aid in the interpretation of radiographic changes seen in horses with PSD. Whereas a diffuse increased radiopacity of the proximal MCIII/MTIII needs to be interpreted with caution, as a mild degree may be seen in sound horses, the multifocal distribution pattern seems to be unique feature of horses with PSD.Keywords: proximal suspensory desmitis / PSD / radiographic changes / suspensory ligament / desmitis Vergleich von röntgenologischen Veränderungen im Bereich des proximalen Metakarpus und Metatarsus bei Pferden mit und ohne Desmopathie des FesselträgerursprungsIn der vorliegenden Studie wurden die Patientendaten von Pferden, die im Zeitraum von 1994 bis 2011 in der Pferdeklinik des Departements für Pferde der Vetsuisse-Fakultät, Universität Zürich wegen einer Desmitis des Fesseltägerursprungs vorgestellt wurden, retrospektiv evaluiert. Die im dorso-palmaren, bzw. dorso-plantaren Strahlengang sichtbar vermehrte Röntgendichte im Bereich des proximalen Metakarpus III/Metatarsus III wurde nach ihrer Lokalisation, Ausdehnung (Länge und Breite), Schweregrad der Veränderungen und Erscheinungsbild ausgewertet. Zudem wurden das Geschlecht, das Alter, die Rasse, die Dauer der klinischen Symptomatik, die erkrankte Gliedmaße und der Lahmheitsgrad ausgewertet. Die Ergebnisse wurden mit einer Kontrollgruppe verglichen. Für die Kontrollgruppe wurden 30 Röntgenbilder eines Karpus und 30 Röntgenbilder eines Tarus je in der dorsopalmaren/plantaren Projektion nach dem gleichen Schema ausge...

Compressive Damage to the Deep Branch of the Lateral Plantar Nerve Associated with Lameness Caused by Proximal Suspensory Desmitis

Abstract: Horses lame because of PSD of the pelvic limb may remain lame after desmitis has resolved because of compression of the DBLPN. Excising a portion of this nerve may resolve lameness.
