Tendon Treatments Utilizing Bone Growth Factor (backup)
Several studies have shown a correlation between the implementation of bone growth factors and the amelioration of the tendon to bone healing. The focus of these studies was primarily on the anterior cruciate ligament (ACL) located un the knee, because of the high volume of incidences of injuries sustained by athletes. The University of Dammam, King Fahd Hospital in Saudi Arabia was able to show that the addition of SHMSP bone growth factor via powder facilitated the process of tendon-graft healing in rabbits. Comparison of this SHMSP test group to the control group illustrated a higher level of formation and organization within the knee. The Hospital for Special Surgery in New York conducted a similar study, in which a collagen sponge containing bone protein was implanted in the ACL of rabbits. In this case, the bone protein isolated from bovine femurs contained several bone morphogenetic protein s, which are part of an important signaling system that aides in the structure of bones. As with the application of SHMSP, the inclusion of bone protein in the collagen sponge was seen to improve the healing process, when compared to control groups with the sponge alone or no sponge. In a separate study also implemented by the Hospital for Special Surgery as well as the University of California, treatment of the anterior cruciate ligament utilized the recombinant human bone morphogenic protein rhBMP-2 in two phases. In phase one, the dosages of noggin, a regulator protein, as well as rhBMP-2 were properly calibrated, and in phase two these proteins carried on synthetic calcium phosphate matrix (CPM) were then injected into the ACL region. The results of this procedure also demonstrated an improvement in the collagen fiber formation between the tendon and the bone. Hence, all three treatments were seen to improve the efficacy of tendon-to-bone healing via different bone growth factors: SHMSP, bone protein, and rhBMP-2.
