Abstract purpose osteoarthritis oa is a global musculoskeletal disorder that affects primarily the knee and hip joints without any fda approved disease modifying therapies animal models are essential research tools in developing therapies for oa many animal studies have provided data for the initiation of human clinical trials

The literature presents mixed results regarding the correlation between nsaid use and the development of symptomatic pseudoarthrosis while most animal model studies indicate increased fracturing and delayed healing in cohorts receiving nsaids there is no consensus on the effects of nsaids on pseudoarthrosis development in humans newer

This model would allow for subsequent testing of new biomaterials to enhance the healing of pseudoarthrosis in osteoporotic bone further this animal model fulfills all criteria to mimic the clinically relevant fracture situation as encountered in geriatric patients

Abstract objective we sought to describe a new model of pseudoarthrosis in rats free of pathogenic species rattus norvegicus albinus spf methods the animals were randomly distributed into two groups were used group 1 control n 6 group 2 experimental n 6 in the control group an access to the femur followed by the synthesis

Therefore many animal models have been developed and reported extensively in the literature to focus on the many features of the disease therefore animal models have played a key role in our understanding of oa pathogenesis and progression figure 2 shows the most commonly used in vivo and in vitro models in oa research and clinical development

Therefore it is important to select suitable animal models of koa to further study the pathogenesis and treatment strategies of the disease at present various koa models have been established for scientific and experimental research the existing animal models of koa include the genetic model surgical induced model and drug induced model

Some postulate that the efficacy of rhbmp may be seen more fully in combination with medical therapy indeed in a murine model bmp 2 combined with zoledronic acid yielded greater bone formation than controls and bmp 2 alone this combination of bmp and bisphosphonates is also included in paley s cross union protocol 13 40

Osteoarthritis oa is the most common form of arthritis and a major source of pain and disability in the adult population there is a significant unmet medical need for the development of effective pharmacological therapies for the treatment of oa in addition to spontaneously occurring animal mode

The advantages of animal models include rapid onset of action a good ability to control disease severity human like anatomy and disease progression and an ethically superior ability to test and track large numbers of subjects 51 unfortunately none of the animal models used to construct oa can faithfully replicate the symptoms and

Bone healing after fracture may either resolve successfully or result in a delayed or altered process also known as non union pseudoarthrosis which is a serious complication of bone fractures that requires important surgical procedures 1 2 these phenomena may be due to loss of vascularity in the healing site and destruction of periosteum and endosteum atrophic pseudoarthrosis or
