    Surgical management for displaced pediatric proximal humeral fractures: a cost analysis
    (Springer Berlin Heidelberg, 2015) Shore, Benjamin; Hedequist, Daniel; Miller, Patricia E.; Waters, Peter; Bae, Donald
    Purpose The purpose of this investigation was to determine which of the following methods of fixation, percutaneous pinning (PP) or intramedullary nailing (IMN), was more cost-effective in the treatment of displaced pediatric proximal humeral fractures (PPHF). Methods: A retrospective cohort of surgically treated PPHF over a 12-year period at a single institution was performed. A decision analysis model was constructed to compare three surgical strategies: IMN versus percutaneous pinning leaving the pins exposed (PPE) versus leaving the pins buried (PPB). Finally, sensitivity analyses were performed, assessing the cost-effectiveness of each technique when infection rates and cost of deep infections were varied. Results: A total of 84 patients with displaced PPHF underwent surgical stabilization. A total of 35 cases were treated with IMN, 32 with PPE, and 17 with PPB. The age, sex, and preoperative fracture angulation were similar across all groups. A greater percentage of open reduction was seen in the IMN and PPB groups (p = 0.03), while a higher proportion of physeal injury was seen in the PPE group (p = 0.02). Surgical time and estimated blood loss was higher in the IMN group (p < 0.001 and p = 0.01, respectively). The decision analysis revealed that the PPE technique resulted in an average cost saving of $4,502 per patient compared to IMN and $2,066 compared to PPB. This strategy remained cost-effective even when the complication rates with exposed implants approached 55 %. Conclusions: Leaving pins exposed after surgical fixation of PPHF is more cost-effective than either burying pins or using intramedullary fixation.

    Pediatric forearm fractures with in situ intramedullary implants
    (Springer Berlin Heidelberg, 2016) Kelly, Brian A.; Shore, Benjamin; Bae, Donald; Hedequist, Daniel; Glotzbecker, Michael
    Purpose The purpose of this investigation is to present our institutional experience with fractures of the pediatric forearm with in situ intramedullary nails. Methods: Six patients treated at our institution for forearm fracture with in situ intramedullary implants between 2004 and 2013 were reviewed. Patient demographics, injury and radiographic characteristics, method of treatment, time to union, and complications were collected from the medical record. Results: 485 patients with forearm fractures were treated with intramedullary implants and six patients presented with a fracture with in situ implants (1.2 %). Fractures in all six patients resulted from a second traumatic event after radiographic healing but before implant removal at a mean of 13.0 months from the initial procedure. One patient had an adequately aligned fracture and was treated with casting without reduction. The remaining five patients (83 %) returned to the operating room for treatment. Two patients underwent rod removal and placement of new intramedullary implants, and two patients were treated with rod removal and plating without attempt at closed reduction. One patient underwent closed reduction in the operating room with successful re-bending of the radial implant and replacement of the ulna implant. All patients went on to uncomplicated radiographic union at a mean 3.6 months. Conclusions: The incidence of fracture of pediatric forearm with in situ intramedullary implants is low. This rare complication can be treated by several different methods, including revision TENS placement, revision to plate fixation, or in situ bending of rods, with the expectation for successful uncomplicated union.
