Understanding the Hill-Sachs Lesion in Its Role in Patients with Recurrent Anterior Shoulder Instability.

The purpose of this study is to provide an update to the orthopedic field in regard to treatment of the Hill-Sachs lesion and anterior shoulder instability. The review highlights the most current knowledge of epidemiology, clinical evaluation, and surgical methods used to treat Hill-Sachs lesions. It also details the relevant clinical and surgical findings that have been made throughout the literature in the past couple of years.

Step-by-Step Technique for Segmental Reconstruction of Reverse Hill-Sachs Lesions Using Homologous Osteochondral Allograft.

Posterior shoulder dislocations are accompanied by high forces and can result in an anteromedial humeral head impression fracture called a reverse Hill-Sachs lesion. This reverse Hill-Sachs lesion can result in serious complications including posttraumatic osteoarthritis, posterior dislocations, osteonecrosis, persistent joint stiffness, and loss of shoulder function. Treatment is challenging and depends on the amount of bone loss. Several techniques have been reported to describe the surgical treatment of ...

Applying Item Response Theory to the Development of a Screening Adaptation of the Goldman-Fristoe Test of Articulation-Second Edition.

Item response theory (IRT) is a psychometric approach to measurement that uses latent trait abilities (e.g., speech sound production skills) to model performance on individual items that vary by difficulty and discrimination. An IRT analysis was applied to preschoolers' productions of the words on the Goldman-Fristoe Test of Articulation-Second Edition (GFTA-2) to identify candidates for a screening measure of speech sound production skills.

Rafting technique without bone grafting in reverse Hill-Sachs lesions.

In this article, we report a case of bilateral posterior shoulder instability, having reverse Hill-Sachs lesions of 25 to 50% of the articular surface on the right side, and of 50% on the left side. The defects were anatomically reconstructed after tuberculum minus osteotomy by elevation of the articular surface and buttressing with raft screws without graft usage. Early rehabilitation with pendulum shoulder exercises was started at third postoperative day. At postoperative sixth week, patient had full rang...

Partial Resurfacing for Humeral Head Defects Associated With Recurrent Shoulder Instability.

Recurrent traumatic shoulder instability is a complex clinical entity that commonly affects young, active patients. Humeral head defects are frequently associated with this condition, but specific treatment to stabilize the shoulder is rarely needed. Management options for defects of the humeral head that do necessitate treatment carry various risks and disadvantages, including the need for bone or soft tissue healing, complications related to hardware, and loss of motion. Partial prosthetic resurfacing has...

Irreducible Anterior Shoulder Dislocation with Interposition of the Long Head of the Biceps and Greater Tuberosity Fracture: A Case Report and Review of the Literature.

Failure of closed manipulative reduction of an acute anterior shoulder dislocation is seldom reported in the literature and is usually due to structural blocks such as soft tissue entrapment (biceps, subscapularis, labrum), bony fragments (glenoid, greater tuberosity) and severe head impaction (Hill-Sachs lesion).

Posterior Fracture Dislocation of the Shoulder: A Modified McLaughlin Procedure.

Bilateral posterior fracture dislocation is a rare injury commonly associated with seizures. When the humeral head defect (reverse Hill-Sachs lesion) is between 20% and 45%, operative fixation using a modified McLaughlin procedure is recommended. This video demonstrates a case of bilateral posterior fracture dislocation after a drug-induced seizure treated with a modified McLaughlin procedure.

COMPARATIVE STUDY on the MANAGEMENT of GLENOHUMERAL JOINT DISLOCATION. Closed Reduction vs. Arthroscopic Remplissage with Bankart Lesion Repair.

Conservative treatment of posttraumatic anteroinferior shoulder instability leads to a high failure rate and consequently high recurrence in young and active population. Each recurrence can increase the structural damage of both bony structures and soft tissues (Hill-Sachs lesion, Bankart lesion). Remplissage technique combined with Bankart repair have been proposed as a treatment option.

Acrochordons on the neck; a remarkable clinical feature of tuberous sclerosis showing different patterns.

Sachs and Lipsker(1) recently published a few patients diagnosed with tuberous sclerosis (TS) presenting with multiple loosely arranged acrochordons (molluscum pendulum) located on the posterior neck showing a lace-like distribution and they proposed the term "molluscum pendulum necklace sign" for these typically located lesions. They detected acrochordons in five cases (17%) in a retrospectively analysed consecutive series of 29 TS patients, of whom four (three adults and one child) remarkably showed this ...

Posterior Shoulder Instability.

Posterior shoulder instability is a relatively uncommon condition, occurring in ∼10% of those with shoulder instability. Because of the rarity of the condition and the lack of knowledge in treatment, it is often misdiagnosed or patients experience a delay in diagnosis. Posterior instability typically affects athletes participating in contact or overhead sports and is usually the result of repetitive microtrauma or blunt force with the shoulder in the provocative position of flexion, adduction, and interna...

The Role of a Natural Mollusk Egg-Derived Ingredient in Facial Appearance.

New cosmeceutical ingredients that improve skin appearance are of interest to the dermatologist. Cryptomphalus aspersa is a snail raised on farms in Spain for its mucinous secretions and eggs. These natural products have been demonstrated in vitro to trigger mesenchymal stem cell differentiation, promote dermal fibroblast and keratinocyte migration, prevent keratinocyte aging, prevent oxidative damage, stimulate the extracellular matrix, and regulate MMPs. This 12-week study enrolled 40 male and female subj...

Eponymous terms in anterior shoulder stabilization surgery.

Shoulder dislocation and its treatment is probably as old as time. Surgical treatment has gained acceptance recently, especially in recurrent cases. Within roughly the last 100 years numerous treatment strategies have been developed and questions elucidated regarding the entity of shoulder instability.Shoulder instability holds many eponymous terms. By means of literature and historical research we present the biographical background of some common eponymous terms and the original publication on which those...

Enzymatic properties of β-N-acetylglucosaminidases.

β-N-Acetylglucosaminidases (GlcNAcases) hydrolyse N-acetylglucosamine-containing oligosaccharides and proteins. These enzymes produce N-acetylglucosamine (GlcNAc) and have a wide range of promising applications in the food, energy, and pharmaceutical industries, such as synergistic degradation of chitin with endo-chitinases and using GlcNAc to produce sialic acid, bioethanol, single-cell proteins, and pharmaceutical therapeutics. GlcNAcases also play an important role in the dynamic balance of cellular O-l...

Magnetic behavior of metastable Fe films grown on Ir(111).

We investigated the growth of ultra-thin Fe films on Ir(111) by means of <i>in-situ</i> low energy electron diffraction and spin-resolved photoemission techniques. We observe a (1x1) diffraction pattern, characteristic of the <i>fcc</i> substrate, below 4 monolayers (ML). Then, a complex superstructure starts to develop, compatible with the formation of <i>bcc</i>-like Fe domains aligned with the substrate according to the Kourdjumov-Sachs orientation relationships. The a...

Effects of thermal and deformation on martensitic transformation and magnetic properties in Fe-17%Mn-4.5%X (X=Co and Mo) alloys.

In this study, the Co and Mo addition to Fe-Mn based alloys was investigated to observe its effect on martensitic phase transformation. Two types of martensite structure occurred from the surface observations made by SEM for Co-added and Mo-added alloys morphologically in austenite grain. With the help of TEM studies, it was understood that these martensite structures are ε (h.c.p.) and α' (b.c.c.). TEM investigations showed that the orientation relationship between γ (f.c.c.) and ε phases corresponds t...
