Health care expenditures are rising in the United States. Recent policy changes are attempting to reduce spending through the development of value-based payment systems that rely heavily on cost transparency. This study was conducted to investigate whether cost disclosure influences surgeons to reduce operating room expenditures. Beginning in 2012, surgeon scorecards were distributed at a regional health care system. The scorecard reported the actual direct supply cost per case for a specific procedure and compared each surgeon's data with those of other surgeons in the same subspecialty...

Corticosteroid injections are used as a nonoperative modality to combat acute inflammation when conservative treatments fail. As female patients are regularly seen by orthopedic physicians, it is essential to identify and understand potential sex-related side effects. The aim of this article is to examine available literature for sex-related side effects of orthopedic-related corticosteroid injections. Although the incidence is low, sex-related side effects, such as abnormal menstruation, lactation disturbances, facial flushing, and hirsutism, are associated with corticosteroid injections...

Suspensory femoral fixation of anterior cruciate ligament (ACL) grafts with fixed loop button and variable loop button devices has gained popularity for ACL reconstruction. This study examined these 2 methods of fixation to determine their effect on graft laxity and patient-reported outcome scores. A database search was performed to identify patients who had undergone ACL reconstruction with either a fixed loop or a variable loop button technique performed by the primary surgeon. Lysholm, Tegner, and 12-Item Short Form Health Survey scores were obtained, and KT-1000 knee ligament arthrometer (MEDmetric, San Diego, California) mechanical knee testing was performed...

Intraoperative proximal femoral fracture, one of the most common complications of total hip arthroplasty (THA), occurs more often in cementless procedures and can affect rehabilitation, hospitalization time, and cost of treatment. The goal of this study was to identify risk factors for intraoperative proximal femoral fracture in THA to identify high-risk groups preoperatively and minimize the incidence of this complication. This nested case-control study included 904 primary cementless THA procedures (769 patients) performed between January 2009 and July 2015...

Accurate sagittal alignment of the femoral component in total knee arthroplasty is crucial for prosthesis longevity, improved function, and patient satisfaction. However, there is variation in the techniques used to attain optimal sagittal femoral component placement in total knee arthroplasty. Femoral component flexion in imageless navigation is based on the mechanical axis rather than the distal femoral anatomy, and there is significant variability in the anatomy of the distal femur. The purpose of this study was to accurately determine the mean distal femoral flexion angle of a representative population and whether variability of the distal femoral flexion angle correlates with race, femur length, or radius of curvature...

To ensure that the femoral stem is placed in the proper position during total hip arthroplasty, the authors developed a patient-specific instrument. A total of 10 total hip arthroplasties were performed with the assistance of the patient-specific instrument during this study. The mean accuracy of stem tilt, varus/valgus, and anteversion was 2.1°±4.1°, 1.0°±0.7°, and 4.7°±1.2°, respectively. No complications were observed and no reoperations were required for any of the patients who underwent surgery included in this study...

Incapacitating articular sequelae in the hip joint have been described for patients with late effects of poliomyelitis. In these patients, total hip arthroplasty (THA) has been associated with a substantial rate of dislocation. This study was conducted to evaluate the long-term clinical and radiologic outcomes of unconstrained THA in this specific group of patients. The study included 6 patients with ipsilateral polio who underwent primary THA between 1985 and 2006. Patients with polio who underwent THA on the nonparalytic limb were excluded...

The authors reviewed the files of all patients with chordomas who were admitted and treated at their institutions from 1975 to 2012. Patients were categorized by early local recurrence and metastasis. Aggressive clinical behavior was defined as local recurrence and metastasis within 24 months of diagnosis and adequate treatment (wide en bloc resection with microscopically negative tumor margins). According to these criteria, 13 patients (14.3%) had aggressive chordomas, including 7 men and 6 women, with mean age of 54 years (range, 37-65 years) at diagnosis and treatment...

Little literature exists examining differences in presentation and outcomes between monomicrobial and polymicrobial vertebral infections. Seventy-nine patients treated for vertebral osteomyelitis between 2001 and 2011 were reviewed. Patients were divided into monomicrobial and polymicrobial cohorts based on type of infection. Various characteristics were compared between the 2 groups. The 26 patients with a polymicrobial infection were older and had a higher mortality rate, lower clearance of infection, larger infection, more vertebral instability, higher erythrocyte sedimentation rate at presentation, and longer mean length of stay...

Stress fractures of the upper extremity have been previously described in the literature, yet reports of isolated injury to the ulna diaphysis or olecranon are rare. The authors describe a case involving an 18-year-old fast-pitch softball pitcher. She presented with a long history of elbow and forearm pain, which was exacerbated during a long weekend of pitching. Her initial physician diagnosed her as having forearm tendinitis. She was treated with nonsurgical means including rest, anti-inflammatory medications, therapy, and kinesiology taping...

Pseudoaneurysms are uncommon in patients with trauma, but can cause diagnostic difficulty and result in significant morbidity. Etiologies range from penetrating and nonpenetrating trauma to operative injury during fracture fixation, arthroscopy, total joint arthroplasty, and hardware loosening and removal. Pseudoaneurysms can conspicuously present as a pulsatile mass with an audible bruit, or as a subtly expanding hematoma. In either case, the complications can be serious if diagnosed late. The authors report a case of a pseudoaneurysm arising from the descending geniculate artery following a tibial plateau fracture...

Derek S Damrow, Scott E Van Valin
Patellar sleeve fractures make up greater than 50% of all patellar fractures. They are essentially only seen in the pediatric population because of the thick periosteum and the distal patellar pole apophysis in this group. These fractures can lead to complications if not treated appropriately and in a timely fashion. Complications of missed or untreated patellar sleeve fractures include patella alta, anterior knee pain, and quadriceps atrophy. These can all result in severe limitations in activity. The authors describe a case of a 16-year-old boy who sustained a patellar sleeve fracture 3 years prior to presentation...

Total hip arthroplasty (THA) and total knee arthroplasty (TKA) are common and successful orthopedic procedures, and as their frequency continues to increase substantially, the focus on limiting perioperative complications heightens. Intraoperative normothermia is recommended to minimize additional complications, but limited evidence exists regarding the effect of hypothermia on orthopedic patients. The purpose of this retrospective study was to determine the incidence of perioperative hypothermia in the setting of TKA and THA, and to evaluate its impact on complications and outcomes...

Rupture of the flexor pollicis longus tendon is a major complication after volar locking plate fixation of distal radius fracture. This study used ultrasonography to assess the flexor pollicis longus tendon and intermediate tissue. The study assessed 27 patients (28 wrists) who underwent removal of the volar locking plate. Before plate removal, radiography and ultrasonography were performed to assess the relation between the flexor pollicis longus tendon and the volar locking plate. Intraoperatively, the authors evaluated the intermediate tissues between the flexor pollicis longus tendon and the distal volar margin of the plate...
