Identification of knee gait waveform pattern alterations in individuals with patellofemoral pain using fast Fourier transform.

PLoS One 2018 14;13(12):e0209015. Epub 2018 Dec 14.

Division of Physical Therapy, College of Health Sciences, University of Kentucky, Lexington, KY, United States of America.

Patellofemoral pain (PFP) is one of the most common overuse injuries of the knee. Previous research has found that individuals with PFP exhibit differences in peak hip kinematics; however, differences in peak knee kinematics, where the pain originates, are difficult to elucidate. To better understand the mechanism behind PFP, we sought to characterize differences in knee gait kinematic waveform patterns in individuals with PFP compared to healthy individuals using fast Fourier transform (FFT).

Clin Orthop Relat Res 2018 Dec 13. Epub 2018 Dec 13.

T. D. Lerch, F. Schmaranzer, S. D. Steppacher, M. Tannast, K. A. Siebenrock, Department of Orthopaedic Surgery, Inselspital, University of Bern, Bern, Switzerland E. N. Novais, Department of Pediatric Orthopedic surgery, Boston Children's Hospital, Boston, MA, USA K. Ziebarth, Department of Pediatric Surgery, Inselspital, University of Bern, Bern, Switzerland.

Background: Prophylactic pinning of the asymptomatic and normal-appearing contralateral hip in patients with unilateral slipped capital femoral epiphysis (SCFE) remains controversial. Understanding the minimal 10-year clinical, functional, and radiographic outcomes of the contralateral asymptomatic hip in unilateral SCFE may be helpful in the decision regarding whether the benefits associated with potentially preventing a SCFE are outweighed by the risk of additional surgery.

Questions/purposes: Among patients with SCFE treated with prophylactic pinning of the asymptomatic and contralateral hip, we sought (1) to determine the complications and reoperations; (2) to evaluate the development of cam deformities and the frequency and severity of osteoarthritis progression; and (3) to characterize hip pain and function as measured by the Harris hip score (HHS) and the Hip Disability and Osteoarthritis Outcome Score (HOOS) at minimal 10-year followup.

Front Psychol 2018 27;9:2233. Epub 2018 Nov 27.

Faculty of Music Education, Levinsky College of Education, Tel Aviv, Israel.

The study of violin recordings as evidence of interpretation and performance approach has been quite extensive throughout recent decades. Findings such as the limited use of vibrato in early recordings, the relative stabilization of tempo and rhythm characteristic of mid-20th century violin playing, or the effect of 'historically informed performance' (HIP) on 'mainstream' (MS) violinists performing early music repertoire, are fundamental in the identification of prevailing norms of practice and changes of style that have occurred over time. However, compared to the considerable amount of research conducted on 20th century playing, studies focusing on 21st century violin performances are still quite limited, and are mostly based on recordings of J.

Rationale: Primary extra-nodal non-Hodgkin lymphoma (PE-NHL) arising in the region of the buttocks is rare. After reviewing the literature from the last 20 years, we found only 3 reported lymphomas originating from soft tissue of the buttocks. In our case, positron emission tomography/computed tomography (PET/CT) was performed for the first time, both before and after treatment, to determine the initial stage of PE-NHL and the curative effects of treatment.

Femoral Intramedullary Alignment in Total Knee Arthroplasty: Indications, Results, Pitfalls, Alternatives, and Controversies.

J Knee Surg 2018 Dec 13. Epub 2018 Dec 13.

Department of Orthopedic Surgery, New England Baptist Hospital, Boston, Massachusetts.

While femoral intramedullary alignment has been found to be the most accurate and reproducible method for proper femoral component orientation in total knee arthroplasty, certain situations preclude the use of intramedullary alignment, such as ipsilateral long-stem total hip arthroplasty, femoral shaft deformity (congenital or post-traumatic), capacious femoral canal, and retained hardware. These cases require alternative alignment guides, that is, extramedullary alignment. The purpose of this study was to determine the accuracy of intramedullary alignment in reproducing the femoral anatomic axis. Read More

Absence of Healing Impairment in Osteotomies Prepared via Osseodensification Drilling.

Int J Periodontics Restorative Dent 2019 Jan/Feb;39(1):65-71

This study sought to qualitatively and quantitatively evaluate the effect of osteotomy preparation by conventional (control group) or OD (OD group) instrumentation on osteotomy healing. An incision of 10 cm was made in the anteroposterior direction over the hip in five sheep, and 15 osteotomies were prepared in the left ilium of the sheep (n = 3/sheep). Three different instrumentation techniques were utilized: (1) conventional/regular drilling (R [recommended by manufacturer]) in a 3-step series of a 2-mm pilot, 3. Read More

Radiation Prophylaxis for Hip Salvage Surgery in Cerebral Palsy: Can We Reduce the Incidence of Heterotopic Ossification?

J Pediatr Orthop 2018 Dec 12. Epub 2018 Dec 12.

Orthopaedic Surgery, Harvard Medical School, Boston Children's Hospital, Boston, MA.

Background: Heterotopic ossification (HO) is a well-recognized complication of proximal femoral resection (PFR) surgery in children with cerebral palsy (CP). Although single-dose radiation prophylaxis (SDRP) has been shown to be effective at lowering the rates of HO following adult total hip arthroplasty; there has been limited study examining the efficacy of SDRP for HO prevention in children with CP undergoing PFR. The purpose of this study was to assess the efficacy of SDRP in children with CP undergoing PFR. Read More
