Background Femoroacetabular impingement (FAI) describes a painful, abnormal (bony) contact between the femoral neck and acetabulum, which, if left untreated, contributes to early osteoarthritis (OA) of the hip. Despite its flat learning curve and long operation times, hip arthroscopy has been used increasingly often in recent years in the surgery of femoroacetabular impingement. The mini-open technique (MOT) offers a possible alternative that addresses the abnormal morphological prominence and allows minimally invasive clearance of hip motion...

A novel detector is described in which solid nitrogen at 17 K is used as the most significant element. Metastable particles impinge on this element and immediately transfer their internal energy to the solid nitrogen producing photons, via excimer formation or otherwise, whose wavelength depends on the metastable being detected and the energy transfer process. The performance of the instrument for the detection of atomic oxygen and molecular nitrogen metastables is discussed.

One of the most common pathologic processes seen in overhead throwing athletes is posterior shoulder pain resulting from internal impingement. "Internal impingement" is a term used to describe a constellation of symptoms which result from the greater tuberosity of the humerus and the articular surface of the rotator cuff abutting the posterosuperior glenoid when the shoulder is in an abducted and externally rotated position. The pathophysiology in symptomatic internal impingement is multifactorial, involving physiologic shoulder remodeling, posterior capsular contracture, and scapular dyskinesis...

PURPOSE OF THE STUDY Peripheral fractures of the talus (lateral talar process and posterior talar process) are rare injuries, easy to miss on examination due to their location and clinical manifestation. They account for 0.3% to 1.0% of all fractures of the talus. An incorrect or late treatment of talar process fractures can result in permanent pain, impingement syndrome, healing in malposition, pseudoarthrosis development and also, due to joint instability, in a potential development of severe subtalar arthritis...

Forest trees are an unparalleled group of organisms in their combined ecological, economic, and societal importance. With widespread distributions, predominantly random mating systems, and large population sizes, most tree species harbor extensive genetic variation both within and among populations. At the same time, demographic processes associated with Pleistocene climate oscillations and land use change have affected contemporary range-wide diversity, and may impinge on the potential for future adaptation...

PURPOSE: While implant impingement and bony impingement have been recognized as causes of poor outcomes in total hip arthroplasty (THA), reports of soft-tissue impingement are rare. To clarify the issue, the effect of anterior capsule resection on hip range of motion (ROM) was quantitatively measured in vivo during posterior approach THA using a CT-based hip navigation system. MATERIALS AND METHODS: For 47 patients (51 hips), hip ROM was measured intraoperatively before and after resection of the anterior hip capsule, and the difference was compared...

The ^{54}Fe nucleus was populated from a ^{56}Fe beam impinging on a Be target with an energy of E/A=500  MeV. The internal decay via γ-ray emission of the 10^{+} metastable state was observed. As the structure of this isomeric state has to involve at least four unpaired nucleons, it cannot be populated in a simple two-neutron removal reaction from the ^{56}Fe ground state. The isomeric state was produced in the low-momentum (-energy) tail of the parallel momentum (energy) distribution of ^{54}Fe, suggesting that it was populated via the decay of the Δ^{0} resonance into a proton...

Valentin Meyer, Laurent Maxit, Christian Audoly
The scattered pressure from a stiffened axisymmetric submerged shell impinged by acoustic plane waves has been investigated experimentally, analytically and through numerical models. In the case where the shell is periodically stiffened, it is shown that helical, Bragg, and Bloch-Floquet waves can propagate. The influence of non-axisymmetric internal frames on these scattering phenomena is nevertheless not well known, as it can considerably increase the computational cost. To overcome this issue, the condensed transfer function (CTF) method, which has been developed to couple subsystems along linear junctions in the case of a mechanical excitation, is extended to acoustical excitations...

BACKGROUND: Since its first description in 1984, periacetabular osteotomy (PAO) has become an accepted treatment for hip dysplasia. The 30-year survivorship with this procedure has not been reported. Because these patients are often very young at the time of surgery, long-term followup and identification of factors associated with poor outcome could help to improve patient selection. QUESTIONS/PURPOSES: Looking at the initial group of patients with hip dysplasia undergoing PAO at the originator's institution, we asked: (1) What is the cumulative 30-year survival rate free from conversion to THA, radiographic progression of osteoarthritis, and/or a Merle d'Aubigné-Postel score < 15? (2) Did hip function improve and pain decrease? (3) Did radiographic osteoarthritis progress? (4) What are the factors associated with one or more of the three endpoints: THA, radiographic progression of osteoarthritis, and/or Merle d'Aubigné-Postel score < 15? METHODS: We retrospectively evaluated the first 63 patients (75 hips) who underwent PAO for hip dysplasia between 1984 and 1987...

BACKGROUND: Hip arthroscopy for femoroacetabular impingement (FAI) is known to produce excellent outcomes, yet some patients do not return to their preinjury level of sport participation. Much literature on return to sport has revolved around anterior cruciate ligament reconstruction and even shoulder instability, but none to date have used qualitative, semistructured patient interviews on patients with hip labral tears. PURPOSE: To understand the factors influencing the decision to return to sport after arthroscopic hip surgery for FAI...
