Abstract
Objective To describe 2 minimally invasive approaches to the spinal canal for treatment of intervertebral disc disease and compare their efficacy to conventional hemilaminectomy. Study Design Experimental; randomized, controlled design. Animals Canine cadavers (n = 10; 5 small and 5 large dogs). Methods Barium-impregnated agarose gel (BA-gel) was injected into the spinal canal at 3 intervertebral spaces of the thoracolumbar spine in each cadaver. Sites were randomly assigned to 1 of 3 approaches: conventional (standard) hemilaminectomy (SH), endoscopic foraminotomy (EF), or foraminotomy via an illuminated port (FP). Computed tomographic scans were performed before and after the procedures. Procedures were compared for duration, bone window size, incision length, complications and percentage of BA-gel removed via repeated measures ANOVA. Results The incisions created during EF and FP were similar and smaller to that of a SH. The duration of EF was prolonged compared to FP and SH. The size of the vertebral window created was greater after SH in large dogs, while no difference was found between procedures in small dogs. The amount of simulated disc material removed from the spinal canal did not differ between procedures, regardless of the size of the dog. Conclusions The two minimally invasive approaches were feasible in small and large dogs. Both techniques allowed similar removal of simulated disc material and may decrease soft tissue morbidity compared to SH.

Abstract Tissue engineering offers a paradigm shift in the treatment of back pain. Engineered intervertebral discs could replace degenerated tissue and overcome the limitations of current treatments, which substantially alter the biomechanical properties of the spine. The centre of the disc, the nucleus pulposus, is an amorphous gel with a large bound water content and it can resist substantial compressive loads. Due to similarities in their compositions, hydrogels have frequently been considere...

Intervertebral disc (IVD) herniation is a common cause of neurologic dysfunction in dogs. During the last 60 years, IVD herniation has been the focus of significant research aiming to describe and understand this debilitating condition and to improve imaging and therapeutic options for clinical patients. This article is a summary of the clinically relevant literature that aims to guide clinicians in their decision making when diagnosing and treating canine IVD disease.

We assessed the long-term outcomes of patients with lumbar disc herniation treated with percutaneous lumbar discectomy (PLD) or microendoscopic discectomy (MED). A retrospective study was performed in consecutive patients with lumbar disc herniation treated with PLD (n = 129) or MED (n = 101) in a single hospital from January 2000 to March 2002. All patients were followed up with MacNab criteria and self-evaluation questionnaires comprising the Oswestry Disability Index and Medical Outcomes Stud...

Abstract Retrospective review of consecutive case series. To assess the safety and efficacy of the microendoscopic approach for treatment of recurrent lumbar disc herniation. The standard surgical approach for the treatment of recurrent disc herniation uses an open technique with a wide exposure. Many would consider a minimally invasive approach such as microendoscopic discectomy (MED) to be contraindicated in the setting of recurrent disc herniation. Sixteen consecutive patients with recurrent ...

The trend of using smaller operative corridors is seen in various surgical specialties. Neurosurgery has also recently embraced minimal access spine technique, and it has rapidly evolved over the past 2 decades. There has been a progression from needle access, small incisions with adaptation of the microscope, and automated percutaneous procedures to endoscopically and laparoscopically assisted procedures. More recently, new muscle-sparing technology has come into use with tubular access. This h...

: During minimally invasive spinal surgery, correct identification of the affected intervertebral disc space is critical. Percutaneous palpation is commonly used, but results may be unreliable. Fluoroscopy is the gold standard but can be cumbersome and exposes operators to ionizing radiation. Spinal ultrasound has been described in veterinary medicine and could be a feasible alternative. This prospective, methods comparison study mimicked a minimally invasive spinal surgery in 10 canine cadavers...

Minimally invasive spine surgery (MISS) seems to have many benefits for human patients and is currently used for various minor and major spine procedures. For MISS, a change in access strategy to the target location is necessary and it requires intraoperative imaging, special instrumentation, and magnification. Few veterinary studies have evaluated MISS for canine patients for spinal decompression procedures. This article discusses the general requirements for MISS and how these can be applied t...
