To report metacarpal fracture repair in a bull.
Clinical report.
Simmental bull (n = 1; 870 kg).
Objective: The objectives of the study were to determine the mechanical properties of a customized buffalo interlocking nail (BIN), intact buffalo tibia, and ostectomized tibia stabilized with BIN in different configurations, as well as to assess the convenience of interlocking nailing in buffalo tibia.
A two-and-half-year-old cow was presented with a defect nonunion of the right metatarsal III/IV bone following a severely comminuted open fracture two months previously. The animal underwent open fixation using a 4.5 mm, broad, 10-hole, dynamic compression plate and autogenous cancellous bone graft collected from the contralateral iliac shaft. The animal started partial weight bearing after the third postoperative day and resumed complete weight bearing after the 10th day. Fracture healing was complete and the implants were removed after the 120th postoperative day.
Objective
To compare the torsional strength of calf metatarsal bones with defects produced by removal of 2 different implants.
Study Design
In vitro mechanical comparison of paired bones with bicortical defects resulting from the implantation of 2 different external fixation systems: the transfixation pin (TP) and the pin sleeve system (PS).
Sample Population
Neonatal calf metatarsal bones (n = 6 pairs).
Methods
Objective:
To compare proximal fragment displacement and the peri-implant strain using a pin-sleeve cast (PSC) system and a transfixation pin cast (TPC) system on a cadaveric calf metacarpal bone fracture model.
Study Design
Experimental.
Sample Population
Cadaveric calf metacarpal bones (n = 6 pairs).
Methods
Objective
To verify if the finite element method can correctly estimate the performance of polyacetal and polyamide 6 intramedullary nails in stabilizing a femoral fracture in calves and to estimate the performance of a polypropylene nail in same conditions.
Study Design
Computational and experimental study.
Sample Population
Finite element models (FEMs).
Methods
Objective
To evaluate biocompatibility of biodegradable sleeves containing antimicrobial agents, designed for local drug delivery to prevent implant-related infection.
Study Design
Synthetic polyester sleeves (a copolymer of glycolide, caprolactone, trimethylene carbonate, lactide) were cast as thin films. The antimicrobial agents incorporated in the sleeves included gentamicin sulfate, triclosan, or a combination of these drugs.
Animals
Adult sheep (n = 15).
Methods
Objective: To describe a technique used for reduction and internal fixation of sacral fractures in cattle.
Study Design: Case series.
Animals: Three heifers aged 19–32 months with deformation of the tail head and tail paralysis attributable to a closed fracture of S5 or S4 and S5.
Objective: To report lumbar vertebrae transverse process fracture repair using a narrow 3.5 mm limited contact dynamic compression plate (LC-DCP) in an adult dairy cow.
Study Design: Case report.
Animals: A 3-year-old Holstein cow.
Methods: Under general anesthesia, fractured left transverse processes of lumbar vertebrae 2–4 were repaired using internal fixation. A narrow 3.5 mm LC-DCP was contoured and secured to the spinous process and the transverse process of each fractured vertebra.
Objective: To determine outcome after repair of long bone fractures in llamas and alpacas.
Study Design: Case series.
Animals: Llamas (n=11) and alpacas (8).
Methods: Medical records (1998–2008) of camelids with long bone fractures were reviewed for history, repair method, and complications. Outcome was also assessed by owner telephone questionnaire.
