Rib fractures are extremely common injuries and vary in there severity from single nondisplaced fractures to multiple segmental fractures resulting in flail chest and respiratory compromise. Historically, rib fractures have been treated conservatively with pain control and respiratory therapy. However this method may not be the best treatment modality in all situations. Operative fixation of select rib fractures has been increasing in popularity especially in patients with flail chest and respiratory compromise. Newer techniques use muscle sparing approaches and precontoured locking plate technology to obtain stable fixation and allow improved respiration. Current reports shows that rib fracture fixation offers the benefits of improved respiratory mechanics and improved pain control in the severe chest wall injury with resultant improvement in patient outcomes by decreasing time on the ventilator, time in the intensive care unit, and overall hospital length of stay.

Hemiarthroplasty as a treatment for femoral neck fractures is controversial with evolving understanding of its complica - tions. One set of complications relates to the use of cement for these procedures. This case study presents two cases that were complicated by retained cement in the acetabulum that was identified in final intraoperative check with x-rays. In both cases, the incision was reopened and retained fragments were removed. We aim to remind the orthopaedic surgery community that this complication can occur even to the careful, experienced surgeon and to recommend the steps necessary to minimize the risk of its occurrence.

Superstorm Sandy gained national attention in late 2012 after its impact on the Northeastern US. In New York City, thousands of residents lost power, and multiple hospitals were forced to evacuate. Bellevue Hospital Center (BHC), the nation's oldest public hospital, was forced to close for the first time in over 275 years. Two patients remained in BHC three days after the primary evacuation without water service and minimal power. Herein, we describe the challenges associated with evacuating a severely obese patient. Obesity management is challenging and at an institutional level must be addressed in emergency preparedness plans.

CASE/METHODS:We present a case of a patient who sustained overlapping dislocation of the pubic symphysis (ODPS), which required an open reduction as well as anterior and posterior pelvic ring fixation. CONCLUSION/CONCLUSIONS:This case report is a valuable addition to the current literature on ODPS because we believe it to be the first report describing a patient who required both anterior and posterior fixation because of pelvic instability.

We sought to determine whether computed tomography (CT) is an accurate tool for evaluation of reduction, prediction of neurologic deficit, and evaluation of need for revision surgery in unstable pelvic ring injuries treated with percutaneous sacroiliac (SI) screw fixation and whether any neural foramen penetration violation is safe. Using medical records and radiographic data, we retrospectively evaluated 46 patients with 51 fractures or widenings of the SI joint that were surgically treated with percutaneous SI screw fixation, either alone or associated with anterior fixation. Using the Young and Burgess classification, there were 3 vertical shear injuries, 13 lateral compression injuries, 17 anterior-posterior injuries, 7 sacral fractures, and 6 combination or unclassifiable pelvic injuries. Satisfactory reduction was obtained in all cases. All patients had postoperative CT scans, and 23 of 51 screws had some foramen penetration with an average of 3.3 mm (range, 1.4-7.0 mm). After percutaneous screw fixation, 10 of 46 patients had postoperative neurologic deficit, 4 of which were unchanged from preoperative evaluation. Of the 6 patients with new or worsened neurologic deficit, CT showed neural foramen penetration of 2.1 and 7.0 mm in 2 patients. Both patients underwent screw revision, resulting in improved neurologic deficit. The remaining 4 patients did not have foramen penetration; their neurologic function improved, with full return at 6 weeks without screw removal. Neural foramen penetration documented with CT did not correlate with neurologic deficit unless the penetration was greater than 2.7 mm. Postoperative CT showing neural foramen penetration was the cause of revision surgery in 2 of 10 patients with postoperative neurologic deficit after percutaneous SI screw fixation. Based on these findings, we recommend postoperative CT only in those cases where there is new neurologic deficit and screw removal if foramen penetration is greater than 2.1 mm. We also describe a new "safe zone" for screw insertion encompassing the superior 2 mm of the sacral foramen with adequate pelvic reduction.

In March 2012, an algorithm for the treatment of intertrochanteric fractures of the hip was introduced in our academic department of Orthopaedic Surgery. It included the use of specified implants for particular patterns of fracture. In this cohort study, 102 consecutive patients presenting with an intertrochanteric fracture were followed prospectively (post-algorithm group). Another 117 consecutive patients who had been treated immediately prior to the implementation of the algorithm were identified retrospectively as a control group (pre-algorithm group). The total cost of the implants prior to implementation of the algorithm was $357 457 (mean: $3055 (1947 to 4133)); compared with $255 120 (mean: $2501 (1052 to 4133)) after its implementation. There was a trend toward fewer complications in patients who were treated using the algorithm (33% pre- versus 22.5% post-algorithm; p = 0.088). Application of the algorithm to the pre-algorithm group revealed a potential overall cost saving of $70 295. The implementation of an evidence-based algorithm for the treatment of intertrochanteric fractures reduced costs while maintaining quality of care with a lower rate of complications and re-admissions.

For almost 15 years bisphosphonates have been the mainstay of prevention and treatment of fragility fractures, particularly in post-menopausal women. As a result, there has been a decrease in fragility fractures, along with the health care costs associated with treating them. However, with all drugs, there are always concerns with side effects and potential complications. Atypical femur fractures have been observed in women taking bisphosphonates, a complication the drug was designed to prevent. There is no definitive link between bisphosphonates and atypical femur fractures and no proto- col to managing these fractures. This review discusses the evolution and development of bisphosphonates and offers the latest information regarding evidence surrounding the link to atypical femur fractures.

The history of limb-lengthening surgery can be traced back to the nineteenth century. Since that time, the orthopaedic community has made tremendous progress in performing successful lengthening procedures. Among the important contributors to the field, Dr. Gavril Ilizarov remains one of the most significant innovators. Because of advancements over the past century, limb lengthening has become a viable method of treating severe bony deformities and defects. This article, the first of a two-part series, reviews the history of distraction osteosynthesis.
