Proximal interphalangeal joint arthrodesis in horses: concepts, indications, and techniques
2021
Anderson Fernando Souza | André Luis do Valle Zoppa
Surgical arthrodesis is effective for treating proximal interphalangeal joint (PIJ) injuries in horses. Despite several techniques described so far, the use of a 3-hole, 4.5mm-locking compression plate, associated with two 5.5-mm transarticular cortex screws, is currently considered the “gold standard.” This review describes the anatomy of the pastern, as well as causes, indications, and possibilities for arthrodesis in the equine PIJ. A description of the current surgical technique for joint fixation is also presented.

Foot rot in small ruminants is highly contagious, causes severe lameness, and impairs fertility and wool and meat production. It is usually treated with parenteral antibiotics, with attendant antibiotic resistance risk, and with bactericidal footbaths, potentially harmful to humans and the environment. An alternative treatment in sheep is proposed based on repeated topical ozonated ointment application. Its effectiveness and safety were evaluated by estimation of acute-phase response, biochemical indicators of organic damage, and antioxidant/oxidant balance (AOB). The study was conducted on ten sheep with Egerton scale 2–3 lesions. Ozone application was repeated every day for seven days. Blood was drawn first (T0) after foot cleaning and before ozonation, then (T1) seven days after the first ozone application, and finally (T2) four days after the last application. High clinical effectiveness was observed, with total recovery by 28 days from the start of treatment. A significant increase in antiradical activity was noted on the basis of a 2,2ʹ-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) assay from 1.16 ± 0.04 μmolTe/mL at T0 to 1.23 ± 0.03 μmolTe/mL at T1, with a slight decrease in oxidative stress. Calculated on the basis of antiradical capacity, AOB was higher at T1 (130 ± 19%) and decreased to 110 ± 16% at T2. Calculated on the basis of reducing power, it was 169 ± 22% at T1 and 131 ± 17% at T2. These results indicated that the AOB is efficient enough to prevent oxidative organ injury and the applied doses of ozone are safe for animals.

2021
Slaughter-Mehfoud, Kathryn M. | McCoy, Annette M.
OBJECTIVE To evaluate synoviocentesis of the equine forelimb digital flexor tendon sheath (DFTS) via a basilar sesamoidean approach (BSA) or distal approach (DA). ANIMALS 21 healthy adult horses without DFTS-related lameness. PROCEDURES The forelimbs of each horse underwent the BSA or DA (21 limbs/approach) performed by 1 individual. The volume of synovial fluid (SF) aspirated, time from skin puncture to collection of SF, and number of attempts to place a needle in the DFTS were compared between approaches. RESULTS An SF sample was successfully aspirated from 16 of 21 (76%) limbs with the BSA and 20 of 21 (95%) limbs with the DA. For the BSA and DA, the number of attempts to obtain SF was 2 and 1, respectively; the median volume of SF obtained was 0.4 and 0.7 mL, respectively; and the median time to SF collection was 17.91 and 18.48 seconds, respectively. Between the approaches, the number of limbs with SF successfully aspirated and number of attempts to collect SF differed significantly, whereas the volume of SF aspirated and time to SF collection did not. CONCLUSIONS AND CLINICAL RELEVANCE Regarding SF collection from forelimb DFTSs in horses without DFTS-related disease, use of the DA had a greater success rate with fewer attempts, compared with findings for the BSA, which may reflect the relative ease of identifying anatomic landmarks for the DA. Results suggested that a DA for DFTS synoviocentesis in horses appears efficient and effective and may minimize limb trauma by requiring fewer attempts for SF sample collection, compared with a BSA.

2021

An intact male, 2.5 kg, 1 ½ years old Domestic Long Hair (DLH) cat was brought to the University Veterinary Clinic, Universiti Malaysia Kelantan with the complaint of inability to stand and inappetence since it was hit by a car a day before presentation. Physical examination and radiography revealed multiple fractures including fracture of the pubis, fracture of the left ischium and fracture of the right femoral neck. There was also a left sacroiliac fracture-luxation. The cat was stabilized with intravenous fluid using normal saline, analgesic, non-steroidal anti-inflammatory, and antibiotic drugs. The sacroiliac fracture-luxation was repaired using a lag screw. The surgical site developed swelling due to seroma formation post operatively, where a drainage tube was placed which necessitated daily wound cleaning and dressing. The cat was able to ambulate with satisfactory weight bearing of the hind limbs at 10 days post-surgery and four weeks later, the cat demonstrated improvement in gait. At 5-months post-surgery, the cat was completely back to its normal gait and ambulation normally.
