Bone Marrow Concentrate Enriched in Platelet Growth Factors Combined With De-mineralized Bone Matrix for Complex Revision and Complex Lower Limb Arthrodesis


Authored by Edgardo R Rodriguez

Complex arthrodesis procedures in the lower limb present a challenging model for successful outcomes, especially in the face of multiple co-morbidities [1]. Not only is this patient population at risk for delayed union and nonunion, the potential for infection and delay in soft tissue healing is also of great concern [2]. Autolo-gous fusion solutions have been used for decades in bone repair procedures in the form of bone grafts (iliac or rib) or bone marrow (Figure 2) aspirate harvested from the marrow cavities with good results. Bone graft harvest comes with inherent challenges, often resulting in do-nor site morbidity [3]. Bone marrow aspirate (BMA) har-vested from the marrow cavities is a mixture of stromal and peripheral blood and has less inherent risk and still provides a potent osteogenic stimulus. Unfortunately, pure BMA has relatively few osteoprogenitor cells per volume and contains a high proportion of red blood cells that can interfere with bone healing [4].

Hip Replacement Surgery: "Part of the Problem or Part of the Solution" Authored by M E Hecht Suppose you’ve just been told you need hip surgery, have a cardiac condition, or you’ve developed diabetes. At this moment you are most likely to be in a doctor’s office, in point of fact the diagnosing doctor’s office, possibly in some state of undress, or having just come from an x-ray, or EKG. There’s no doubt about it, as an experience, it’s up front and personal, not matter how succinct and professional the announcement- up front, personal, and threatening as hell. I mean the doctor may have run several miles this morning, had a carb loaded breakfast, or not a scrap of pain in any of his major or minor joints, he’s in good shape. But you’ve just been told your body has betrayed you. What’s more, if you’re a card player you could say at this point, that you’re the doctor holds cards, spades, and big Casino. In short, it can be a moment of inequality second to none. How

Intraarticular Injection of Platelet Rich Plasma (PRP) and Hyaluronic Acid (HA) in Early Knee Osteoarthritis-Juniper Publishers

Image
Orthopedics & Rheumatology -Juniper Publishers Introduction: This is a comparative study between HA and PRP injection in knee osteoarthritis. A total of 224 patients with knee osteoarthritis (grade I and II) were enrolled in this study. The arthritic changes were graded according to the Kellgren and Lawrence radiological scale. In the first group, 116 patients were intra-articularly injected with PRP three times with two weeks interval. In the second group, 108 patients were injected with three intra-articular injections of hyaluronic acid with two weeks interval. The patient’s age and sex were comparable in both groups. In the PRP group, the mean of follow up was 30.34 months, while in the hyaluronic injection group, it was 28.886 months. Results: At the end of follow, in the PRP group, 85 patients (73.3%) had satisfactory results, while 31 patients (26.7%) had unsatisfactory. The mean International Knee Documentation Committee score (IKDC) before

Treatment of Intertrochanteric Hip Fractures in Elderly High Risk Patients with External Fixation

Image
Orthopedics and Rheumatology - Juniper Publishers                                                 Abstract In 6 elderly patients intertrochanteric fractures were treated, using FERN external fixation system. All fractures healed within 4 months. Three patients had a superficial pin tract infection and one deep infection. Shortening of 1cm or more was seen in 2 patients. Varus angulation of 5º or more was seen in 2 patients but this seems to be well tolerated by the elderly. External fixation represents an excellent alternative for the surgical treatment of high-risk, elderly patients. Go to Introduction Intertrochanteric fractures are very common among elderly patients. These fractures are cause of significant morbidity and mortality in conservatively treated patients. Because of that the treatment of choice is surgery. The most commonly used surgical method is internal fixation which is associated with intraoperative blood loos and prolonged anesthesia. The elderly patients are high
