Use of Platelet-rich Plasma in the Treatment of Recalcitrant Sinus Tracts: A Case Series.

چکیده
UNLABELLED Sinus tract formation is common in a wide variety of wounds and can be difficult to manage. Nonsurgical techniques for treating sinus tracts have generally been disappointing, though many nonsur- gical options have been explored including dermal matrix injection, platelet-derived growth factors, fibrin sealant, and phenytoin. This case series explores the treatment of nonhealing chronic wound-related si- nus tracts with autologous platelet-rich plasma (PRP) in a series of patients in a single center, hospital-based, chronic wound care cen- ter. METHODS PRP was prepared using the Harvest SmartPRep pro- cedure. During processing, the blood was separated into two distinct chambers: one containing packed red blood cells, and the other with autologous platelet concentrate and plasma supernatant. The plasma was injected into the entire sinus tract beginning from the base of the tract. RESULTS Nine of 12 patients healed, and three did not heal and required other interventions (excision and flap repair). All patients, ex- cept one, received only one PRP injection. One case of infection that could be directly attributed to the PRP injection was reported. All other patients experienced no pain, discomfort, or signs or symptoms of in- fection. CONCLUSION PRP injection can be a useful technique in cases of straight, relatively short, persistent sinus tracts.

Platelet-Rich Plasma for Frozen Shoulder: A Case Report
Frozen shoulder is a glenohumeral joint disorder that perturbs movement because of adhesion and the existence of fibrosis in the shoulder capsule. Platelet-rich plasma can produce collagen and growth factors, which increases stem cells and consequently enhances the healing. To date, there is no evidence regarding the effectiveness of platelet-rich plasma in frozen shoulder. A 45-year-old man ...
