Resumo
Background: Coxofemoral dysplasia (CFD) is the abnormal development of the hip joint, mostly affecting large breeds, and is characterized by subluxation or complete luxation of the femoral head. Among the conservative therapeutic options, cell therapies with stem cells for CFD provides potential by the countless possibilities of therapeutic application, especially those related to the chronic and/or degenerative diseases treatment, which could be a key point for the bone and joint repair. The objective was to report a bilateral CFD case in a dog, treated with intra-articular application of mesenchymal stem cells (MSC), with 0, 30, 60 and 90 days, and further evaluations. Case: A 2-year-old male Akita dog was referred to the Veterinary Hospital Harmonia (HVH) located in the city of Recife, Pernambuco, presenting clinical signs of hip pain, lameness and pelvic limbs hopping. By orthopedic examination, pain was observed at the cranial and caudal extension of the pelvic limb, and at flexion, abduction and adduction of the limb, as well as moderate muscle atrophy and presence of joint crackling. By coxofemoral radiography performed in ventrodorsal projection, it were detected bilateral femoral head subluxation, thickening of the femoral neck and the presence of intraarticular osteophytes. These findings are compatible with the degeneration caused by the presence of CFD. Laboratory tests performed such as hemogram and biochemical had no changes. Thus, the patient had intra-articular application of allogeneic MSC, derived from adipose tissue, obtained by private company. For stem cell applications, arthrocentesis of the hip joints was performed one at a time, using a 5 mL syringe and 16G needle for aspiration of 2 mL synovial fluid, for discard and application of stem cells. After aspiration, the syringe containing the MSC were fitted to the 16G needle for the implant. After the...
