Total Elbow Replacement in Swine: Surgical Technique and Initial Clinical Experience in a Kunekune Sow.

Objective:  The aim of this study was to describe the development of a total elbow replacement (TER) technique in swine and report the outcome of TER in a Kunekune sow (61 kg) with severe elbow osteoarthritis.

Methods:  The technique was developed by operating on three pig cadavers (Yorkshire 40-50 kg). The TATE Elbow implant fit was confirmed with modeling to the patient's computed tomography imaging.

Revision of Hip Luxation in a Canine Total Hip Replacement Caused by a Greater Trochanteric Fracture Secondary to an Inflammatory Granuloma.

A hip luxation 3 years following a cementless total hip replacement was diagnosed in a 4.7-year-old neutered male Lagotto Romagnolo that presented with a non-weight-bearing left pelvic limb lameness. Orthogonal radiographs revealed a left hip luxation and an osteolytic fracture of the greater trochanter.

Interlocking Nails and Minimally Invasive Osteosynthesis.

Reviews of clinical outcomes led to the foundation of a new approach in fracture management known as biological osteosynthesis. As intramedullary rods featuring cannulations and locking devices at both extremities, interlocking nails are well suited for bridging osteosynthesis. Unique biological and mechanical benefits make them ideal for minimally invasive nail osteosynthesis and an attractive, effective alternative to plating, particularly in revisions of failed plate osteosynthesis.

Study Design: Prospective clinical case series.

Animals: Eleven dogs and 4 cats with traumatic nonarticular humeral fractures.

Minimally invasive lag screw fixation of sacroiliac luxation/fracture using a dedicated novel instrument system: Apparatus and technique description.

Objective: To describe a novel Sacroiliac Luxation Instrument System (SILIS™) and its application in minimally invasive osteosynthesis (MIO) of sacroiliac luxations/fractures (SIL/F). The SILIS was designed to provide stable SIL/F reduction and accurate sacral screw placement while reducing personnel exposure to ionizing radiation during intraoperative fluoroscopy.

Study Design: Descriptive, proof of concept cadaveric study.

Two Interesting Cases of Meralgia Paraesthetica.

Meralgia paraesthetica (MP) is a condition originally described by Bernhardt in 1878 and was eventually named by Roth in 1895. It is caused by compression of the lateral femoral cutaneous nerve (LFCN) resulting in varying types of discomfort. Severity of the symptoms can range from mildly uncomfortable to painfully disabling.

Comparison of open reduction versus minimally invasive surgical approaches on screw position in canine sacroiliac lag-screw fixation.

Objective: To compare accuracy and consistency of sacral screw placement in canine pelves treated for sacroiliac luxation with open reduction and internal fixation (ORIF) or minimally invasive osteosynthesis (MIO) techniques.

Methods: Unilateral sacroiliac luxations created experimentally in canine cadavers were stabilized with an iliosacral lag screw applied via ORIF or MIO techniques (n = 10/group). Dorsoventral and craniocaudal screw angles were measured using computed tomography multiplanar reconstructions in transverse and dorsal planes, respectively.

Retrospective evaluation of concurrent intra-abdominal injuries in dogs with traumatic pelvic fractures: 83 cases (2008-2013).

Objective: To report the occurrence of intra-abdominal injury (IA) in dogs with pelvic fractures due to blunt trauma, to evaluate for association between characterization of pelvic fractures and the presence of IA, and to evaluate for association between IA and other specific clinical conditions.

Design: Retrospective case series (2008-2013).

Setting: University teaching hospital.

The Use of Chemotherapeutics for the Treatment of Keloid Scars.

Keloid scars are pathological scars, which develop as a result of exaggerated dermal tissue proliferation following cutaneous injury and often cause physical, psychological and cosmetic problems. Various theories regarding keloidogenesis exist, however the precise pathophysiological events remain unclear. Many different treatment modalities have been implicated in their management, but currently there is no entirely satisfactory method for treating all keloid lesions.

Minimally invasive plate osteosythesis of fractures of the radius and ulna in a primate.

A 25-year-old female mandrill (Mandrillus sphinx - a primate and part of the Old World monkey group) was presented with a mildly comminuted, diaphyseal, radial fracture associated with a transverse ulnar fracture. Minimally invasive plate osteosynthesis techniques were used to achieve fixation of both the radial and the ulnar fractures. First, closed fracture reduction was achieved with a distraction frame consisting of a motorized circular external skeletal fixator.

Interlocking nails and minimally invasive osteosynthesis.

Interlocking nailing of long bone fractures has long been considered the gold standard osteosynthesis technique in people. Thanks to improvements in the locking mechanism design and nail profile, a recently developed veterinary angle stable nail has become the first true intramedullary fixator providing accurate and consistent repair stability while allowing semirigid fixation. As a result, indications for interlocking nailing have expanded to include treatment of periarticular fractures, corrections of angular deformities and revisions of failed plate osteosyntheses.

Perioperative imaging in minimally invasive osteosynthesis in small animals.

Perioperative imaging using various appropriate modalities is critical to the successful planning and performance of any orthopedic surgery. Although not an absolute prerequisite, the use of intraoperative imaging considerably facilitates the smooth and effective execution of minimally invasive osteosynthesis (MIO). However, the risk of overexposure to radiation is real, particularly when considering its insidious effect over time.
