چکیده مقاله:
BACKGROUND: Hip Dysplasia is a frequent orthopedic disease that is characterized by early joint sublux- ation. The DARthroplasty technique is a two-part process that involves applying bone graft to increase the femoral head coverage with a low morbidity rate and the long term is known results. OBJECTIVES: This study was aimed to investigate the radiographic and clinical changes after transplanting the rib allograft impregnated with PRP and MSCs in the treatment of hip dysplasia in a dog. The current study was conducted to assess the effectiveness of modified DARthroplasty. METHODS:12 dogs were selected, all of them operated by the modified induced hip dysplasia. Afterward, an approximately 25 mm segment rib was harvested and transplanted at slot approximately 7 mm broad and 12.5 mm high, close craniodorsally to the joint capsule origin, and secured with a 2 mm cortical bone screw in each recipient dog. PRP and MSCs were injected into the gap around allograft. Subsequently, they were divided into 3 subgroups of 4 dogs in each group, control, PRP, and MSCs. 6 months after the surgery, all dogs were subjected to clinical and radiographic evaluations. RESULTS:Clinically, all dogs showed no sign of orthopedic disorder which was determined by Ortolani sign, and no muscle atrophy and pain were elicited in the hip joint. One dog showed a slight lameness degree about two weeks and one case had seroma but was immediately treated by aspiration and pressure bandage. Upon ra- diographic examination, no dislocation of the rib allograft could be detected. Bone proliferation was observed. Dogs in all groups showed NA and PC increase with MSCs (5.25 ± 0.3 and 22.5 ± 0.81), PRP group (6.5 ± 0.43 and 20.5 ± 0.12) and control group (6.5 ± 0.35 and 19 ± 1.23) at six months postoperatively. CONCLUSIONS: This study showed that rib bone allograft with PRP and MSCs can be quite effective on joint congruency and stability in symptomatic dogs due to hip dysplasia.
