The purpose of this study was to assess if behavior and emotional function, as measured by the Pearson Behavioral Assessment Survey for Children, Second Edition (BASC-2) in patients and parents, changes with differing treatment protocols in patients with adolescent idiopathic scoliosis (AIS). One previous study showed abnormal BASC-2 scores in a su...

The goal of this study is to quantify adolescents use of e-cigarettes, determine the influence of parental smoking behavior on adolescents, and assess adolescents and parent knowledge of health risks associated with e-cigarette use.

Background: Ankle arthrodesis has historically been the standard of care for end-stage ankle arthritis, however total ankle arthroplasty (TAA) is considered a reliable alternative. Our objective was to compare three-dimensional foot and ankle kinetics, kinematics, and determine the ankle power that is generated during level walking and stair ascent...

Background: The Salto Talaris is a fixed-bearing implant first approved in the US in 2006. While early surgical outcomes have been promising, mid- to long-term survivorship data are limited. The aim of this study was to present the survivorship and causes of failure of the Salto Talaris implant, with functional and radiographic outcomes. Methods:...

Background In total ankle replacement (TAR), correct positioning of the implant is crucial. Malposition of the components may increase contact pressures and diminish prosthesis survival. The effect of sagittal tibiotalar alignment on functional outcomes after fixed-bearing TAR remains unclear, however, and no studies have compared fixed-bearing imp...

Introduction: With the increasing use of total ankle arthroplasty (TAA), new implants with varied configurations are being developed every year. This study aimed to assess the early complications, reoperations, and radiographic and clinical outcomes of this novel implant. Methods: A retrospective analysis of 64 consecutive ankles that underwent a p...

Introduction: Correct positioning of implants in total ankle arthroplasty (TAA) is a key step to ensure the longevity of the prosthesis. Patient-specific instrumentation (PSI) via preoperative computed tomography for TAA was developed and made available through PROPHECY (Wright Medical, Memphis, TN). The purpose of this study was to compare the use...

Introduction: Implant positioning is critical in total ankle replacement (TAR). However, the effect of sagittal tibiotalar alignment on functional outcomes in fixed-bearing TAR remains unclear. Furthermore, no studies comparing different fixed-bearing implants with respect to the anteroposterior position of the talar component have been performed t...

Background Total ankle arthroplasty (TAA) continues to exhibit a relatively high incidence of complications and need for revision surgery compared to knee and hip arthroplasty. One common mode of failure in TAA is talar component subsidence. This may be caused by disruption in the talar blood supply related to the operative technique. The purpose o...

Category Ankle Arthritis Introduction/Purpose Total ankle replacement (TAR) continues to exhibit a relatively high incidence of complications and need for revision surgery, particularly when compared to knee and hip arthroplasty. One common mode of failure in TAR is talar component subsidence. This may be caused by disruption in the talar blood su...

Background While metatarsus primus elevatus (MPE) has been implicated in the development of hallux rigidus, previous studies have presented conflicting findings regarding the relationship between MPE and arthritis. This may be due to the variety of definitions for MPE and the radiographic measurement techniques that are used to assess it. Additiona...

Introduction: Complication rates after lumbar spine fusion range from 5.6% to 31.4%. Multiple investigations have examined risk factors for complications following lumbar spine fusion, though none have performed a comprehensive investigation of the association between a variety of determinants of health and the risk of postoperative major complica...

Purpose There have been no prospective studies investigating gastrointestinal (GI) symptoms of patients with adolescent idiopathic scoliosis (AIS) following posterior spinal fusion (PSF). The purpose of this study was to evaluate the incidence and severity of self-reported GI symptoms following PSF. Methods In all, 40 AIS patients undergoing PSF w...

Study design: Prospective study of 92 patients. Objectives: To determine if the incidence of clinically significant psychological and emotional distress in adolescent idiopathic scoliosis (AIS) patients is higher than the general population and if this correlates with deformity severity. Summary of background data: Adolescents with scoliosis m...

Severe deformity in patients with end-stage ankle arthritis has long been considered a relative contraindication for total ankle replacement. However, advancements in surgical techniques and a better understanding of the importance of correcting foot deformity in conjunction with ankle deformity have led to satisfactory outcomes in this group of pa...

Background: With the increasing use of total ankle arthroplasty (TAA), new implants with varied configurations are being developed every year. This study aimed to assess the early complications, reoperations, and radiographic and clinical outcomes of the Infinity TAA. To date, clinical results of this novel implant have not been published. Method...

Background Patient-specific instrumentation (PSI) for TAA is a novel technology with several potential benefits. The primary goal of this study was to compare the use of PSI with the standard referencing guide (SRG) in regards to accuracy of tibial implant positioning. Operative time, fluoroscopy time and accuracy of PSI preoperative reports were a...

Total ankle arthroplasty has evolved significantly in the last 2 decades. Improvements in surgical technique and instrumentation, as well as advances in implant design, have contributed significantly to the increased adoption of ankle replacement for the treatment of ankle arthritis. Achieving proper alignment and correct positioning of the compone...

Background The number of opioids prescribed and used has increased precipitously over the past 2 decades for a number of reasons and has led to increases in long-term dependency, opioid-related deaths, and diversion. Most studies examining the role of prescribing habits have investigated nonoperative providers, although there is some literature des...

PurposeRecently, several authors have proposed techniques for improving the fusion rate in pediatric posterior occipitocervical fusion including a variety of implants and the use of bone morphogenetic protein. A technique by Koop et al. using a periosteal flap for occipitocervical arthrodesis was described in 1984. MethodsA straight incision is mad...

Category Ankle, Ankle Arthritis Introduction/Purpose The use of smartphone applications to assist with medical care is increasing. An important aspect of total ankle arthroplasty is to allow patients to remain active and mobile following their surgery while decreasing discomfort. To our knowledge, no other studies have quantitatively and qualitati...

Category Ankle Arthritis Introduction/Purpose Placement of the talar component in total ankle replacement (TAR) is technically challenging and malposition can occur. Implant alignment can affect both contact stresses at the articulation of the prosthesis, as well as forces at the bone implant interface, and survivorship of the implant. In mobile b...

Category Midfoot/Forefoot Introduction/Purpose Hallux rigidus occurs in 2.5% of the population over 50 years of age and is commonly treated with cheilectomy or arthrodesis. While long-term outcomes following cheilectomy for hallux rigidus are promising, questions remain concerning indicators for failure of a cheilectomy. The goal of this study was...

Introduction/Purpose: While Metatarsus Primus Elevatus (MPE) has been implicated in the development of hallux rigidus, previous studies have presented conflicting findings regarding the relationship between an elevated first metatarsal and arthritis. This may be due to the variety of definitions for MPE and the radiographic measurement techniques...
