“…Since the SL is maximally loaded due to maximal extension of the fetlock joint, when during trot only one fore and hind limb is on the ground, the risk of SL desmitis may increase (Holmstrom et al 1994, Walker et al 2013. As shown by Riemersma et al, the mean maximal strain and mean maximal load in walk and trot is higher in the SL compared to the SDFT (Holmstrom et al 1994, Riemersma et al 1996, Walker et al 2013 The degree of lameness in horses with PSD in a fore-or hindlimb varies greatly (Dyson 2007, Genovese et al 2011, Gibson et al 2002. In the present study, horses with forelimb PSD had significantly lower lameness scores than horses with hindlimb PSD.…”

“…Several authors have stated that radiographic changes are very common in horses with chronic PSD, but are rare in acute cases (Dyson 2003, Gibson et al 2002, Gomez 2003). Duration of lameness was known in 103 horses, and most of these (70) had been lame for more than 28 days, which classified them as chronically lame (> 28 days).…”

“…Lesions of the proximal suspensory ligament are a common cause of lameness in performance as well as pleasure horses (Gibson et al 2002, Gomez 2003, Trump et al 2014 and are thought to be the result of acute or chronic repetitive trauma. Degenerative processes may also play a role in PSD (Kold et al 2011, Mero et al 2002, Mero et al 2005.…”

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...

“…The main role of the SL is to support the metacarpophalangeal joint and, together with the dorsal sesamoid ligaments, to protect it from hyperextension during the stance phase of the stride. Moreover, the SL limits palmar bending of the third metacarpal bone when compressive stresses act on the dorsal cortex of the bone (Gibson and Steel, 2002;Shikh Alsook et al, 2013).…”

“…In the forelimb the SL arises from the distal row of the carpal bones and the proximal palmar aspect of the third metacarpal bone (MC III). In the hindlimb, it originates from the proximal plantar aspect of the third metatarsal bone (MT III) and a minor portion from the distal row of tarsal bones (Gibson and Steel 2002). Between the middle and distal third of the MC/MT III the body of the suspensory ligament divides into two branches.…”

SummaryThis study aimed to investigate the precision of ultrasonographic measurements of the body and branches of the suspensory ligament and straight and oblique distal sesamoidean ligaments in equine fore-and hindlimbs. Ultrasonographic measurements of the horses suspensory apparatus are used for diagnostic purposes but their precision has not been assessed yet. Fourteen sound horses underwent ultrasonographic examination of all four limbs by two operators, twice. Longitudinal and transverse ultrasonographic images were used to measure the depth, width, circumference and cross-sectional area at locations determined by anatomical features. Inter-and intraoperator comparisons were made and their variability was evaluated using agreement indices and 95% limits of agreement. This method showed that the depth of the suspensory ligament branches from longitudinal images and their circumference from transverse images, and circumference of the straight sesamoidean ligament in the distal pastern were the more reliable of the measurements. All measurements of the suspensory ligament body and the oblique sesamoidean ligaments had a low reliability. The reliability of measurements of the size of the suspensory apparatus should be considered when making clinical judgements from ultrasonographic images. Particular caution should be exercised with measurements of the suspensory ligament body and the oblique distal sesamoidean ligament.Keywords: horse / suspensory apparatus / ultrasonography / measurement / precision / diagnostic imaging Präzision ultrasonographischer Messungen am Fesseltrageapparat des PferdesZiel der Studie war es, die Präzision ultrasonographischer Messungen des Fesselträgerkörpers, der Fesselträgerschenkel und des geraden und der schrägen Gleichbeinbänder an Vorder-und Hinterbeinen des Pferdes zu untersuchen. Ultrasonographische Messungen des Fesseltrageapparats des Pferdes werden zu diagnostischen Zwecken zwar genutzt, ihre Präzision wurde aber noch nicht untersucht. In der Studie wurden 14 gesunde Pferde ultrasonographisch untersucht; zweifach an allen vier Gliedmaßen von zwei Untersuchern. Longitudinale und transversale Sonogramme wurden benutzt, um die Tiefe, die Weite, den Umfang und die Fläche an durch die Anatomie definierten Stellen zu bestimmen. Die inter-Unterschiede zwischen und von den Untersuchern (inter-and intraoperator variability -bzw. Reproduzierund Wiederholbarkeit) wurde mittels des mean agreement index (Übereinstimmung der Mittelwerte) und 95% limits of agreement (Über-einstimmungsgrenzen) bestimmt. Die Messung der Tiefe im longitudinalen Sonogramm in den Bereichen der Fesselträgerschenkel und die Messung des Umfangs im transversalen Sonogramm in den Bereichen der Fesselträgerschenkel und des geraden Gleichbeinbandes in der distalen Fesselbeuge gehörten zu den zuverlässigeren Messungen. Alle Messungen im Bereich des Fesselträgerkörpers und der schrägen Gleichbeinbänder haben eine geringe Zuverlässigkeit, was bei klinischen Entscheidungen berücksichtigt werden muss.Schlüsselwörter: Pfe...
