Gizelle Amora, Neusa Hamada, Luiz C Pinho
Stenochironomus munteanpurin sp. n. is described and illustrated in all life stages, except eggs, from Brazil. The male is very similar to Stenochironomus quadrinotatus Borkent, 1984 due to same overall pattern of pigmentation. The new species can be distinguished from the other related species principally in immature stages: larva with labral lamella arranged in two groups with one or two conical-shaped teeth, spicules of pecten epipharyngis arranged in a row, unequal and irregularly distributed sizes, SI bifurcated, SII pinnate, SIII pinnate setae and, larval exuviae is compacted; pupa with shagreens being in all TI, less number of hooklets in TII, TVII without shagreens and presence of shagreen in conjunctive III/IV and IV/V...

Two new species from the Caucasus belonging to the genera Albanura and Persanura are described and illustrated in detail. Albanura secunda sp. n. is distinctive because of the presence of chaetae E on the head as well as three ordinary chaetae on tubercles De of thorax III and abdomen I-III. Additionally, the species can be recognized by the absence of chaeta O on the head and presence of 3+3 chaetae Di on abdomen V. The most important characters that can be used to distinguish Persanura lencarana sp. n. are the labral formula, an increased number of chaetae De on thorax II and III, and the number of chaetae Di on the thorax and abdomen V...

BACKGROUND: Hip arthroscopic treatment is not equally beneficial for every patient undergoing this procedure. Therefore, the purpose of this study was to develop a clinical prediction model for functional outcome after surgery based on preoperative factors. METHODS: Prospective data was collected on a cohort of 205 patients having undergone hip arthroscopy between 2011 and 2015. Demographic and clinical variables and patient reported outcome (PRO) scores were collected, and considered as potential predictors...

The cheek line (face reading) is an aesthetic element of the facial profile. The purpose of our study was to investigate the changes in the cheek line after mandibular setback surgery. Forty patients (20 female and 20 male, mean (SD) age 22 (5) years) were diagnosed with mandibular prognathism and treated by intraoral vertical ramus osteotomy alone. Cephalograms were obtained before operation (T1), at least a year postoperatively (T2), and final surgical changes over a year (T2-T1). The cheek line and landmarks (soft and hard tissues) were compared using the paired t test...

The purpose of this study was to assess biomechanical differences among overhand, three-quarter, and sidearm arm-slot professional baseball pitchers. It was hypothesized that kinematic-and-kinetic differences would be found among the three groups, with sidearm pitchers demonstrating greater movement along the transverse plane, and overhead pitchers demonstrating greater movement along the sagittal plane. Based upon arm-slot-angle at ball-release, 30-overhand, 156-three-quarter, and 21-sidearm pitchers were tested using a 240-Hz-motion-analysis-system, and 37 kinematic-and-kinetic parameters were calculated...

Objective The International Cartilage Repair Society classification is the one mainly used to define chondral defects. However, this classification does not include delamination. The objective of the study is to describe the characteristics of this lesion to better explain its classification in the context of chondral lesions of the hip. Design We performed a retrospective analysis of 613 patients who underwent hip arthroscopy. In this group, the incidence, localization, histological characteristics, and association to femoroacetabular impingement as well as to other intraarticular lesions of acetabular delamination (AD) were analyzed...

OBJECTIVE:   To present recommendations for the diagnosis, management, outcomes, and return to play of athletes with superior labral anterior-posterior (SLAP) injuries. BACKGROUND:   In overhead athletes, SLAP tears are common as either acute or chronic injuries. The clinical guidelines presented here were developed based on a systematic review of the current evidence and the consensus of the writing panel. Clinicians can use these guidelines to inform decision making regarding the diagnosis, acute and long-term conservative and surgical treatment, and expected outcomes of and return-to-play guidelines for athletes with SLAP injuries...

Hal David Martin
Hip labral reconstruction has proven to be a successful technique in restoring normal labrum function. However, sometimes revision surgery is required. A recent, well-designed prospective study provides significant support for revision labral reconstruction, showing how it leads to improved hip mechanics and reduction in pain. The success of the study design and this report is a testament to an educational institution dedicated to fellowship training.

BACKGROUND: Although 3D-isotropic MR arthrography has been characterized as a substitute imaging tool for rotator cuff tear (RCT) and labral lesions, it has not been commonly used in clinical practice because of controversy related to image blurring and indistinctness of structural edges. PURPOSE: To perform a comparison of the diagnostic performance of 3D-isotropic MR arthrography and 2D-conventional MR arthrography for diagnosis of RCT (solely RCT, full/partial-thickness supraspinatus [SST]-infraspinatus [IST] tear, or subscapularis [SSc] tear) and labral lesions...

CASE: Arthroscopic labral repair has resulted in excellent functional outcomes. However, extensive labral damage or diminutive size of the labrum may preclude a repair. In these cases, labral augmentation serves as an operative treatment option. We report the case of a labral augmentation with 7.5 years of follow-up, including intraoperative reexamination, which highlights the ability of an iliotibial band autograft to incorporate with the native labrum. CONCLUSION: When indicated in an appropriate patient, labral augmentation with an iliotibial band autograft is an established technique that can result in an excellent outcome...

REVIEW
Michael B Rose, Thomas Noonan
Glenohumeral internal rotation deficit (GIRD) is an adaptive process in which the throwing shoulder experiences a loss of internal rotation (IR). GIRD has most commonly been defined by a loss of >20° of IR compared to the contralateral shoulder. Total rotational motion of the shoulder is the sum of internal and external rotation and may be more important than the absolute value of IR loss. Pathologic GIRD has been defined as a loss of IR combined with a loss of total rotational motion. The leading pathologic process in GIRD is posterior capsular and rotator-cuff tightness, due to the repetitive cocking that occurs with the overhead throwing motion...

BACKGROUND: Various protocols exist for magnetic resonance arthrogram (MRA) of the shoulder, including 3D isotropic scanning and positioning in neutral (2D neutral MRA), or abduction-external-rotation (ABER). HYPOTHESIS: MRA does not improve diagnostic accuracy for labral tears when compared to magnetic resonance imaging (MRI) performed using 3-Tesla (3T) magnets. METHOD: Systematic review of the Cochrane, MEDLINE, and PubMed databases according to PRISMA guidelines...

BACKGROUND: Literature regarding surfing injuries is scarce and most studies report a high number of minor injuries. Recent literature suggests that musculoskeletal injuries are more common than previously reported. In the mid 2000s, competitive surfing has seen an increase in aerial maneuvers, as they have become more highly rewarded by the judging panel, which may be contributing to a change in injury patterns. Our goal was to evaluate orthopedic injuries in professional surfers. HYPOTHESIS: Orthopedic injuries in professional surfers are diverse and have evolved with skill and technology...
