Background: Psychiatric disorders are common, and their functional consequences may be underappreciated by non-mental health-care providers. There exist limited data regarding the frequency of psychiatric illness in patients who sustain orthopaedic polytrauma. The purpose this study was to describe prevalence with polytrauma, determine whether illnesses were identified accommodated trauma providers, and, finally, investigate any associations between postoperative complications illness....
Background: Injuries to the anterior cruciate ligament (ACL) are common, and a number of knee morphological variables have been identified as risk factors for an ACL injury, including posterior tibial slope (TS). However, limited data exist regarding innate population differences in TS. Purpose: To (1) establish normative values medial lateral TS; (2) determine what between ages, sexes, races; (3) how internal or external rotation (as occurs during sagittal motion) influences stereotactic...
The role of myeloid derived suppressor cells (MDSCs) in promoting tumorigenesis is well-established, and significant effort being made to further characterize surface markers on MDSCs both for better diagnosis as potential targets therapy. Here we show that the B cell receptor adaptor molecule CD79a unexpectedly expressed immature bone marrow cells, upregulated generated multiple different mouse models metastatic but not non-metastatic cancer. activated response soluble factors secreted by...
Tibial torsion and femoral anteversion are common rotational abnormalities in children, their courses most often benign self-resolving. Although neither usually requires surgical treatment, the decision to perform a derotational osteotomy is based on degree of functional impairment. Neither condition thought influence development osteoarthritis hip or knee; however, date there have been no large scale studies confirming this.Tibial version 1158 cadaveric tibiae femora were measured using...
Background Knee dislocations are rare injuries with potentially devastating vascular complications. An expeditious and accurate diagnosis is necessary, as failing to diagnose injury can result in amputation; however, the best diagnostic approach remains controversial. Questions/purposes We asked: (1) What patient factors predictors of after knee dislocation? (2) utilities palpable dorsalis pedis or posterior tibial pulses, presence an ankle-brachial index (ABI) 0.9 greater? Methods A...
Objectives Sagittal alignment of the lumbosacral spine, and specifically pelvic incidence (PI), has been implicated in development spine pathology, but generally ignored with regards to diseases hip. We aimed determine if increased PI is correlated higher rates hip osteoarthritis (HOA). The effect on knee (KOA) was used as a negative control. Methods studied 400 well-preserved cadaveric skeletons ranging from 50 79 years age at death. Each specimen’s OA were graded using previously described...
The etiology of slipped capital femoral epiphysis (SCFE) is multifactorial, but the role sagittal balance pelvis as a contributing factor to its development has not been well studied. Our primary purpose was determine whether smaller pelvic incidence (PI), position-independent anatomic parameter that regulates orientation, could be increases shear stress in epiphyseal growth plate and potentially contributes SCFE. We also set out acetabular retroversion associated with SCFE.We obtained 14...
Recent evidence has suggested that cam morphology may be related to alterations in the capital femoral growth plate during adolescence. The purpose of this study was evaluate relationship between extension and a longitudinal radiographic study.We used historical, collection identify 96 healthy adolescents (54 boys 42 girls) with at least 5 consecutive annual radiographs left hip including closure physis. We reviewed 554 anteroposterior measure modification alpha angle Nötzli superior...
When individuals with asymmetric lower extremities present for evaluation of limb-length inequality, correction can occur at the tibia, femur, or in both bones; however, there are limited data available to justify either technique. The aim this study is examine normal ratio tibia length/femur length (T/F), and explore relationship between T/F osteoarthritis spine, hips, knees.Bone lengths 1152 cadaveric femora tibiae from Hamann-Todd osteological collection were measured. Degenerative joint...
Readmissions after total joint arthroplasty have become a key quality measure in elective surgery the United States. The Affordable Care Act includes Hospital Readmission Reduction Program, which calls for reduced payments to hospitals with excessive readmissions. This policy uses method determine excess readmission ratios and calculate payment adjustments hospitals, however, it is unclear whether rates are an effective metric. reasons or conditions associated THA been well established but...
To analyze long-term functional outcomes in patients with posttraumatic infected tibial nonunions having undergone bone transport hexapod external fixator.Retrospective cohort study.Level 1 trauma center.Thirty-eight of the tibia.Resection nonunion application stacked fixator for transport.Functional outcome was measured using short Musculoskeletal Functional Assessment (sMFA). Parameters included age, sex, presence diabetes, smoking, use a free flap, defect size, length frame, fixation...
Pantalar dislocations without associated talar fracture are rare and have high risks of complications, including infection, osteonecrosis, posttraumatic osteoarthrosis. Limited information on later function exists. This study evaluated complications outcomes following pantalar dislocation fracture.Nineteen patients were identified with open (n = 14) or closed 5) fracture. Ten male 9 female a mean age 39.6 years (range, 19 to 68 years) included. Open injuries underwent surgical debridement....
Tibia fractures are the most common long bone fracture. Criteria for closed and open reduction based on amount of fracture shortening, angulation, rotation, with high success rates achieved if acceptable alignment is maintained. However, there exists limited data available regarding long-term consequences specific deformation patterns.The tibiae 2898 cadaveric skeletons were manually inspected evidence Specimens midshaft identified as candidates study; intraarticular excluded. Fracture...
To describe clinical results and functional outcomes of knee dislocations treated with a consistent strategy within our institution.Retrospective case series.Level 1 trauma center.One hundred nineteen patients were at one institution between 2000 2014 for dislocation.Knee range motion, instability, complications recorded. Musculoskeletal Function Assessment (MFA) Lysholm scores obtained after minimum year.Sixty-three early noted in 36 (32%), an overall amputation rate 9.2% (8 3 late...
