RESUMO
Introduction: Sesamoid bones absorb and disperse weight from the metatarsal bones. Sesamoid injuries occur primarily in dancers and runners, with nonoperative management as the first line of treatment. Due to the lack of secondary blood supply, the sesamoids are at risk for osteonecrosis and nonunion fractures. The literature supporting orthobiologics for the treatment of sesamoid injuries is limited. Methods: In this case, a 28-year-old female dancer with sesamoid osteonecrosis underwent a leukocyte-rich platelet-rich plasma (LR-PRP) injection to the fibular sesamoid. Results: The patient reported significant improvement in pain at the 2-month follow-up and returned to regular auditions at the 3-month follow-up. At 2-year follow-up, the patient's symptoms returned to baseline. Conclusion: This is the first known case of sesamoid osteonecrosis treated with LR-PRP. LR-PRP should be considered in the treatment of sesamoid osteonecrosis in those who show limited improvement with standard conservative measures.
RESUMO
PURPOSE: To serve as a guide for non-operative physicians in the management of femoroacetabular impingement syndrome and provide an algorithm as to when to refer patients for potential surgical management. RECENT FINDINGS: Supervised physical therapy programs that focus on active strengthening and core strengthening are more effective than unsupervised, passive, and non-core-focused programs. There is promising evidence for the use of intra-articular hyaluronic acid and PRP as adjunct treatment options. Recent systematic reviews and meta-analyses have found that in young active patients, hip arthroscopy demonstrates improved short-term outcomes over physical therapy. The decision for the management of FAIS is complex and should be specific to each patient. Consideration of the patient's age, timing to return to sport, longevity of treatment, hip morphology, and degree of cartilage degeneration is required to make an informed decision in the treatment of these patients.
