Aims: To compare radiographic failure and re-operation rates of anatomical coracoclavicular (CC) ligament reconstructional techniques with non-anatomical techniques after chronic high grade acromioclavicular (AC) joint injuries. Patients and methods: We reviewed chronic AC joint reconstructions within a region-wide healthcare system to identify...

Purpose Variation in rib numbering has been noted in adolescent idiopathic scoliosis (AIS), but its effect on the reporting of fusion levels has not been studied. We hypothesized that vertebral numbering variations can lead to differing documentation of fusion levels. Methods We examined the radiographs of 161 surgical AIS patients and 179 contro...
Article
A relationship between spinal distraction and correction of the curvature of scoliosis has long been recognized. While attempts have been made to define the height that is lost with progression of scoliosis, much less information is available to define the height that is gained as a result of surgical correction of the curve and to quantify additio...
Article
: Evaluation of extension-based low back pain in young athletes with suspected pars injury may include a referral for skeletal single photon emission computed tomography (SPECT). However, the diagnostic yield of this technique in children with low back pain before the age of 10 years remains uncertain. We examined a series of consecutive SPECT scan...
Article
The use of topical hemostatic agents is widespread and has been shown to reduce bleeding during a wide variety of surgical procedures. Nonetheless, as biologically active agents, there is potential for allergic reactions to these products. This is a report of intraoperative anaphylaxis to gelatin associated with the use of two topical hemostatic ag...
Article
Purpose: The purpose of this study was to establish and analyze a simplified scoring system based on anatomic imaging measurements to predict recurrent instability after primary arthroscopic shoulder capsulolabral repair. Methods: All patients undergoing primary arthroscopic anterior capsulolabral repair of the shoulder were reviewed. Patients w...
Article
Objectives: To evaluate the maximal force generated by magnetically controlled growing rods (MCGRs) at three different lengthened positions. Summary of background data: The introduction of MCGRs has been met with great enthusiasm by surgeons managing early-onset scoliosis. These devices offer the potential to decrease the cost and morbidity asso...
Article
Beta‐blockers are one of the most commonly prescribed classes of antihypertensive medications during pregnancy. Previous studies reported an association between beta‐blocker exposure and intrauterine growth restriction. Whether some beta‐blocker subtypes may be associated with higher risk is not known. This is a retrospective cohort study of pregna...
Article
Objectives The goal of this study is to report the prevalence, aetiology and clinical outcome of pregnant women with heart failure. Methods This is a retrospective community-based cohort study that included pregnant women in the Kaiser Permanente Health System between 2003 and 2014. Women with heart failure were identified using International Clas...
Article
Randomized trials showed no survival benefit with statin therapy in heart failure (HF) patients with reduced ejection fraction (HFrEF). Whether these results are generalizable to HF patients with preserved ejection fraction (HFpEF) or with mid-range ejection fraction is unclear. In a cohort of 13,440 patients with HF, 9,903 (73.7%) were treated wit...

Summary of Background Data: The introduction of MCGRs has been met with great enthusiasm by surgeons managing early-onset scoliosis. These devices offer the potential to decrease the cost and morbidity associa...
Article
Purpose: We postulated that, with microsurgical technique, vascular reconstruction with interpositional vein grafts in the pediatric population is safe and results in sustained vascular patency and excellent midterm outcomes. Methods: Twenty children with brachial artery injuries were treated with interpositional vein grafting at a tertiary pedi...
Article
β-Blockers are the most commonly used class of medication for treating cardiac conditions in pregnant women.¹ Despite the common use of this class of medication, data that support its safety are limited.
Article
Purpose: To compare femoral version measured with a fluoroscopic Dunn view taken at the time of hip arthroscopy with values derived from axial magnetic resonance imaging (MRI) scans. Methods: Of 159 hip arthroscopies performed from January 2014 through March 2015, 50 patients had magnetic resonance imaging (MRI) scans with a protocol that incorp...
Article
Background: The optimal management of stroke prophylaxis in hemodialysis patients with atrial fibrillation is controversial. Objective: The objectives of this study were to determine the risk of mortality, stroke, and bleeding associated with the use of warfarin in hemodialysis patients with atrial fibrillation. Methods: This is a retrospectiv...
Article
Background: Cam deformity is associated with epiphyseal extension onto the anterosuperior femoral head-neck before physeal closure. A century ago, anatomists speculated that this femoral prominence acts as a pulley bar to withstand capsular compression in hip extension with pressure concentrated where the zona orbicularis (ZO) joins the iliofemora...

Background The goal of this study was to determine the prevalence of atrial fibrillation and atrial flutter (AF) in pregnant women and to examine the impact of AF on maternal and fetal outcomes. Methods and Results Between January 1, 2003 and December 31, 2013, there were 264 730 qualifying pregnancies (in 210 356 women) in the Kaiser Permanente S...
Article
Purpose: To determine the percentage of AO B3 distal radius fractures that lose reduction after operative fixation and to see whether fracture morphology, patient factors, or fixation methods predict failure. We hypothesized that initial fracture displacement, amount of lunate facet available for fixation, plate position, and screw fixation would...
Article
: The range of injury severity that can be seen within the category of type II supracondylar humerus fractures (SCHFs) raises the question whether some could be treated nonoperatively. However, the clinical difficulty in using this approach lies in determining which type II SCHFs can be managed successfully without a surgical intervention. : We rev...
Article
Objectives: We measured biomechanical stability in simulated supracondylar humeral fractures fixed with each of 6 pin configurations, 2 with associated medial comminution, and developed a technique for reproducible pin placement and divergence. Methods: A transverse supracondylar osteotomy was performed on 36 biomechanical humerus models. Of the...
Article
Because communication is something that is often taken for granted, many people do not consciously think about communication habits and behaviors. When patients are questioned concerning important attributes of a doctor, they say they want someone who respects and listens to them. In a time of increasing malpractice litigation, physicians need to e...
Article
Occasionally, the treatment of a pediatric supracondylar humeral fracture is delayed owing to lack of an available treating physician, necessitating transfer of the child, or delay in availability of an operating room. The purpose of this study is to prospectively evaluate whether delayed pinning of these fractures affects the outcome or number of...
Article
Patients with arthrogryposis often report decreased ambulation and physical activity. Given that skeletal mineralisation is responsive to force, we identified the need to characterize bone mineral density and functional measures in this population, and conducted a cross-sectional study to establish a reference for future investigations. Thirty cons...
Article
Temporary elbow stiffness after the treatment of a supracondylar humeral fracture in a child is often a concern of parents. However, little attention has been devoted to documenting, longitudinally, the time required for motion recovery. The purpose of the present study was to provide a prospective, longitudinal evaluation of elbow motion in a larg...
