Risk Factors For The Development Of A Symptomatic Contralateral Discoid Lateral Meniscus, Jason Nielson, Sean Davis, Aaron Gray, Brock Wentz

Western Journal of Orthopaedics

Background: Discoid menisci (DM) are oval or disc shaped menisci, differing from the normal crescent shaped meniscus. This difference in shape may be one factor as to why DM are more prone to injury when compared to normal menisci. The purpose of this study was to evaluate potential risk factors that may lead to the development of symptoms, requiring arthroscopic saucerization in adolescents with a history of symptomatic DM in the contralateral extremity. Methods: We retrospectively reviewed 126 patients with an arthroscopic diagnosis of DM to evaluate for the presence of a symptomatic contralateral DM variant. Mildly symptomatic DM status …

SUMMARY OF BACKGROUND DATA: In the absence of an outcome instrument specifically designed and validated for traumatic spinal column injury patients, it is difficult to measure the effect size of various treatment options. The AOSpine Knowledge Forum Trauma initiated a project and developed the AOSpine PROST consisting of 19 items.

METHODS: Patients were recruited from two level-1 North-American trauma centers. For concurrent validity, next …

Can The Contralateral Knee Effectively Estimate Pre-Injury Patellar Height? A Control Study, Benjamin Albertson, Andrew Ockuly, Ian Fletcher, Daniel Wascher

Western Journal of Orthopaedics

Introduction: Patellar height abnormalities have been associated with patellar instability, which is common among adolescents and young adults. Pre-injury patellar height is often unknown in patients with a patellar instability episode. The purpose of this study was to determine whether patellar height of one knee could effectively estimate patellar height of the contralateral knee in control patients between the ages of 13 and 25 years. Methods: A retrospective chart review was conducted to identify 40 patients who obtained bilateral knee radiographs with no prior surgical intervention or diagnosis of injury to the extensor mechanism. CatonDeschamps Index (CDI) was measured by …

Association Between Bone-Specific Physical Activity Scores And Pqct-Derived Measures Of Bone Strength And Geometry In Healthy Young And Middle-Aged Premenopausal Women., Sojung Kim, Breanne S Baker, Pragya Sharma-Ghimire, Debra A Bemben, Michael G Bemben

Faculty Scholarship for the College of Science & Mathematics

The aim of this study was to determine if bone-specific physical activity questionnaire (BPAQ) scores were positively related to bone health in healthy young and middle-aged premenopausal women. The total BPAQ was a stronger predictor of bone strength and bone mineral density of hip in young women as compared to middle-aged premenopausal women.

PURPOSE: The purpose of this study was to determine whether the BPAQ scores were predictive indices of volumetric BMD (vBMD), bone strength, and bone geometry in young and middle-aged premenopausal women.

METHODS: Healthy young (n = 60) and middle-aged premenopausal women (n = 54) between the ages …

Subperiosteal Abscess Of The Distal Radius In A 13-Year-Old Boy: A Case Report, Anastasiya K. Haponyuk, Deana M. Mercer

UNM Orthopaedic Research Journal

Children and adolescents have the tendency to develop osteomyelitis in metaphyseal sinusoids because turbulent blood flow increases the probability of bacterial growth. Osteomyelitis in children is frequently misdiagnosed owing to lack of symptoms and specific findings from laboratory tests. Without rapid antibiotic treatment of osteomyelitis, complications such as subperiosteal abscesses may occur. We describe a 13-year-old boy who underwent irrigation and debridement to treat a subperiosteal abscess of the right distal radius and ulna, caused by acute osteomyelitis. After debridement, the patient was placed on a continuous 6-week course of nafcillin infusion through a peripherally inserted central catheter (PICC). The …

Simultaneous Avulsion Fractures Of The Tibial Tuberosity Of Both Knees In A 14-Year-Old Boy: A Case Report, Margaret E. Pusateri, Selina R. Silva, Christopher A. Mcgrew

UNM Orthopaedic Research Journal

Fractures of the tibial tuberosity are uncommon injuries in adolescents, representing an estimated 0.4% to 2.7% of all pediatric fractures. Most of these injuries occur in young, active males commonly between the ages of 12 to 17 years. Sports, particularly those involving jumping or sudden starts and stops, are most often implicated. Injuries of the tibial tuberosity of both knees are especially rare, with little more than 30 cases reported in the past 60 years. We present a 14-year-old male football player with simultaneous avulsion fractures of the tibial tuberosity of both knees. We reviewed the anatomy, mechanisms of injury, …

Brachial Artery Vasculitis And Associated Stenosis Presenting As Elbow Pain In A 16-Year-Old Soccer Player: A Case Report, Eric R. Reynolds, Andrew D. Ashbaugh, James P. Toldi, Deana M. Mercer, Mark Langsfeld, Christopher A. Mcgrew

UNM Orthopaedic Research Journal

Chronic vascular occlusion in the upper extremity can result from repetitive trauma, atherosclerosis, proximal embolic events, hypercoagulable states, and systemic diseases such as collagen vascular disease and vasculitis. Considerable functional impairment can result from these maladies; however, sometimes the condition develops slowly with minimal effect on the patient. We describe a 16-year-old soccer player with slow-progressing elbow pain and loss of range in motion caused by brachial artery vasculitis and resultant brachial arterial stenosis. Although vascular insults and lesions rarely cause chronic vascular occlusion, physicians should consider this possibility in patients with localized pain or atrophy, especially if the condition …

Childhood chronic kidney disease (CHD) poses multiple threats to bone accrual; however, the associated fracture risk is not well characterized. This prospective cohort study included 537 CKD in Children (CKiD) participants. Fracture histories were obtained at baseline, at years 1, 3, and 5 through November 1, 2009, and annually thereafter. We used Cox regression analysis of first incident fracture to evaluate potential correlates of fracture risk. At enrollment, median age was 11 years, and 16% of patients reported a prior fracture. Over a median of 3.9 years, 43 males and 24 females sustained incident fractures, corresponding to 395 (95% confidence …

The Effect Of Scoliotic Deformity On Spine Kinematics In Adolescents., Sarah Galvis, Douglas Burton, Brandon Barnds, John Anderson, Richard M. Schwend, Nigel Price, Sara Wilson, Elizabeth Friis

Manuscripts, Articles, Book Chapters and Other Papers

Background: While adolescent idiopathic scoliosis (AIS) produces well characterized deformation in spinal form, the effect on spinal function, namely mobility, is not well known. Better understanding of scoliotic spinal mobility could yield better treatment targets and diagnoses. The purpose of this study was to characterize the spinal mobility differences due to AIS. It was hypothesized that the AIS group would exhibit reduced mobility compared to the typical adolescent (TA) group.

Methods: Eleven adolescents with right thoracic AIS, apices T6-T10, and eleven age- and gender-matched TAs moved to their maximum bent position in sagittal and coronal plane bending tasks. A Trakstar …

Rothman Institute Faculty Papers

Malnutrition has been linked to serious complications in patients undergoing elective total joint arthroplasty (TJA). This study prospectively evaluated 2,161 patients undergoing elective TJA for malnutrition as defined by either an abnormal serum albumin or transferrin. The overall incidence of malnutrition was 8.5% (184 of 2,161) and the rate of overall complications in the malnourished group was 12% as compared to 2.9% in patients with normal parameters (P55years-old undergoing TJA and is associated with a significant increase in post-operative complications.

Common Peroneal Nerve Palsy Following Total Hip Arthroplasty: Prognostic Factors For Recovery., Jai Hyung Park, Bryan Hozack, Peter Kim, Robert Norton, Steven Mandel, Camilo Restrepo, Javad Parvizi

Rothman Institute Faculty Papers

BACKGROUND: Common peroneal nerve palsy, although rare, is a serious complication of total hip arthroplasty. Although several publications have dealt with the risk factors for peroneal nerve palsy, there is little literature regarding the time it takes for the nerve to recover and the factors that influence its recovery. The purpose of this study was to elucidate the clinical course of this injury and identify prognostic factors for recovery.

METHODS: From January 2000 to December 2007, 7969 primary and 1601 revision total hip arthroplasties were performed at our institution. Common peroneal nerve palsy developed following thirty-one (0.32%) of these procedures. …

Risk Factors For Wound Complications After Ankle Fracture Surgery., Adam G Miller, Andrew Margules, Steven M Raikin

Department of Orthopaedic Surgery Faculty Papers

BACKGROUND: The overall rate of complications after ankle fracture fixation varies between 5% and 40% depending on the population investigated, and wound complications have been reported to occur in 1.4% to 18.8% of patients. Large studies have focused on complications in terms of readmission, but few studies have examined risk factors for wound-related issues in the outpatient setting in a large number of patients. A review was performed to identify risk factors for wound complications tracked in the hospital and outpatient setting.

METHODS: Four hundred and seventy-eight patients underwent open reduction and internal fixation of an ankle fracture between 2003 …
