暂无%X <B>UNASSIGNED: </B>Nearly half a million interbody fusions are estimated to be performed in the US each year, many of which involve complex reconstruction. The ability to limit seroma formation is vital to a seamless postoperative recovery.<BR><B>UNASSIGNED: </B>A retrospective review was performed for patients undergoing fusion procedures along with flap reconstruction over a period of 20 months. Cohorts reflect a temporal practice shift where use of hydrolyzed collagen powder (HCP) was initiated for hypothesized seroma prevention. Outcomes and associated metrics were used for intergroup comparison.<BR><B>UNASSIGNED: </B>The study included 76 patients, of whom 47 were treated with HCP and 29 were not. Control patients had significantly fewer postoperative seromas than experimental ones (6.9% vs 27.7%; P = .03). The cohorts had no significant differences in time until final drain removal or in number of spinal levels involved (7.8 vs 7.1 days; P = .33, 8.5 vs 8.4 levels; P = .90). Rates of wound dehiscence, hematoma, or infection did not differ significantly between control and experimental patients (3.4% vs 12.8%, P = .17; 0% vs 0%; and 6.9% vs 10.6%, P = .58, respectively).<BR><B>UNASSIGNED: </B>The use of HCP led to a 4-fold increase in postoperative seromas in patients undergoing spinal fusion with flap reconstruction. This was regardless of all analyzed demographic and procedural factors, with the exception of age, whereby control patients were found to be on average slightly younger than experimental counterparts.
