Nonrigid external fixation of a joint is designed to restrict abnormal joint movement and facilitate healing of traumatized ligaments and capsule tissue with minimizing the impact of immobilization on articular homeostasis and cartilage metabolism. Weight bearing and joint motion minimize muscle atrophy and loss of bone mineral and allow controlled loading of the ligaments, thereby improving their strength and functionality. This article describes simple, cost effective techniques for the percutaneous application of external fixators to the elbow, coxofemoral, and tarsal joint of dogs.
Advances in the treatment and monitoring of diabetes mellitus in humans are being applied to feline patients. The authors present the current approaches to the treatment of diabetic cats as well as their experience with the use of new monitoring technology.
Over the last decade, osseointegrated dental implants have become an integral part of the restorative dental armamentarium. Reproducible success rates approaching 100% further emphasize the importance and value of this treatment modality. Still, a significant waiting period is required between implant placement and prosthesis delivery, which necessitates a two-surgery approach for implant protection during healing. This article discusses the development of an animal model that is being used to investigate methods of manipulating the healing process of bone next to dental implants. Osseointegration has been shown to occur at 6 weeks in the rat tibia model, demonstrating many of the same characteristics seen in humans. The successful manipulation of bone next to the implant surface may ultimately lead to a surgical protocol for the placement of dental implants requiring only one surgery, significantly reducing the overall healing time.
Chronic orofacial pain for which there is no apparent organic basis is often referred to as psychogenic pain. It is an important problem for all health professionals and has been estimated to afflict some 5 to 7 million Americans. This article reviews the nature and possible mechanisms of the various disorders associated with psychogenic pain in dental practice and methods for its management.
