“…The probe frequency had to be decreased to 4 MHz in claws with greater sole thickness in older buffaloes, which is consistent with the results of T Tsuka, R Nishimura, M Hishinuma, Y Murahata, M Yamashita, K Azuma, T Osaki, N Ito, Y Okamoto and T Imagawa [39], who reported that better images were obtained at lower ultrasound probe frequencies. Ultrasonography has been validated to provide objective measurements of the claws in cattle, and has been used to study, for example, the effect of changes in sole soft-tissue thickness and/or echogenicity on the development of claw horn disruption lesions [37,40,41], to objectively guide claw trimming [39,42], and to diagnose pedal bone fractures [43]. Here, we con rmed the utility of ultrasonography for examining the claws of buffaloes.…”

Background Lameness has been associated with compromised animal welfare and reduced productivity in dairy cattle herds worldwide. However, little is known about the prevalence of claw lesions in the dairy buffalo population in Egypt. Furthermore, the optimum measurements for claw trimming in buffalo are unknown. A cross-sectional cadaver study was conducted where 135 pair buffalo hind feet were collected from 4 slaughterhouses and examined for the presence of claw lesions. The proportion and associated 95% confidence interval (CI) of each type of lesion were calculated. A separate set of healthy claws (n = 26) underwent ultrasonography (US) and computed tomography (CT). The agreement between US and CT measurements was assessed using Passing–Bablok regression and intraclass correlation coefficient. The CT measurements were used to calculate trimming recommendations. Results At least one lesion was identified in 242 claws (89.6%, 95% CI = 85.4–93.0). In healthy claws, poor to moderate agreement was identified between US and CT measurements. The average ± standard deviation (SD) minimum recommended external wall length of the lateral and medial claws in heifers was 7.1 ± 0.36 cm and 7.5 ± 0.35 cm, respectively. The average ± SD minimum recommended external wall length in buffaloes over five years of age was 8.2 ± 0.27 cm and 8.4 ± 0.39 cm for the lateral and medial claws, respectively. Conclusions The study found a high prevalence of claw lesions in buffalo in Egypt, the clinical significance of which requires further elucidation. Recommended measurements will help guide claw trimming in buffalo to minimise lesions.

“…Severe trauma is the most common cause, and affected cattle show acute onset of signs of weight bearing lameness ( 3 ). Radiographic and/or ultrasonographic examination are critical in diagnosing the fracture ( 2 , 4 ). In cattle, the usual treatment of phalangeal fractures consists of immobilizing the affected digit by applying an orthopedic claw block on the healthy partner claw of the affected limb ( 5 ) or using an external coaptation technique ( 6 , 7 ).…”

Fracture of the digits is a well-known orthopedic condition in adult cattle, and mainly the distal phalanx (P3) is involved. To our knowledge, the treatment of fractures of the middle (P2) and proximal (P1) phalanges with orthopedic claw blocks has not yet been described in cattle and other ruminants. This report describes the first case of the successful management of a P1 fracture in an adult European bison. A 5-year-old female European bison (Bison bonasus) presented with severe weight bearing lameness of the left hind limb and a marked soft tissue swelling accentuated over the plantar and lateral aspects of the proximal and middle phalanges, associated with multifocal light bluish discoloration of the skin (hematoma) and increased local temperature. The cow was examined and managed because of a severely comminuted fracture of the lateral P1 of the left hind limb. Application of an orthopedic block on the healthy medial partner claw allowed to reduce the load of the affected digit. Combined with the administration of non-steroidal anti-inflammatory drugs, it supported immobilization and recovery. Radiographic re-evaluations at weeks 6, 9, and 11 after the injury revealed progressive callus formation and fracture consolidation. From week 9 onwards, until the end of treatment, no lameness was observed. The healing process was good, and both clinical and radiographical improvement were evident after immobilizing the affected digit by applying an orthopedic claw block on the healthy partner claw and administering non-steroidal anti-inflammatory drugs.
