OBJECTIVES: Part of the psoriasis patients with musculoskeletal complaints will have inflammation of the entheses. Entheseal inflammation is difficult to assess by clinical examination only. Therefore, we aimed to determine the frequency of clinically relevant ultrasound inflammation at the most commonly assessed entheses (MASEI; Madrid Sonographic Enthesis Index) in primary care psoriasis patients with one or more tender entheses. METHODS: Adult primary care psoriasis patients with musculoskeletal complaints (tender enthesis or arthritis at physical examination) had an ultrasound examination of seven entheses according to the MASEI...

BACKGROUND: Blepharoplasty is a common aesthetic surgery performed worldwide. In Asians, too high eyelid folds after blepharoplasty cause an unsatisfactory aesthetic outcome that is difficult to correct. In this article, the authors propose surgical techniques to correct the high eyelid fold after blepharoplasty. METHODS: During a 4-year period, 213 secondary blepharoplasties were performed to correct high folds. Postoperative results were reviewed, graded, and analyzed...

Tendon curvature plays a key role in mechanical gain (amplifying the joint excursion relative to fiber length change) during joint motion, but the mechanism remains unresolved. A three-dimensional finite element (FE) model was used to investigate the influence of intramuscular fiber orientation upon the curvature pattern of the Achilles tendon during active muscular contraction. Two simulation models, with fiber pennation angles of θ = 25° and 47° were tested for the gastrocnemius and soleus muscles. A smaller pennation angle (25°) of the soleus muscle fibers was accompanied by a large change in curvature whereas a larger pennation angle (47°) of the soleus muscle was accompanied by small effects...

INTRODUCTION: Muscle strain of the gastrocnemius medial head mainly occurs at the musculotendinous junction (MTJ), and stiffness is a risk factor. Shear wave elastography (SWE) measures elasticity by determining the propagation velocity. The aim of this study was to measure the elasticity of the normal muscle and aponeurosis in the MTJ of the gastrocnemius medial head using SWE, thus obtaining information relevant to muscle strain at this point. MATERIALS AND METHODS: Forty-one volunteers (82 legs) were recruited and the gastrocnemius medial heads were examined at four points: three on the aponeurosis, namely at the center of the MTJ (Central), 10 mm proximal to it (Proximal) and 10 mm distal to it (Distal); and at one on the muscle belly (Muscle)...

Background. Muscles not only shorten during contraction to perform mechanical work, but they also bulge radially because of the isovolumetric constraint on muscle fibres. Muscle bulging may have important implications for muscle performance, however quantifying three-dimensional (3D) muscle shape changes in human muscle is problematic because of difficulties with sustaining contractions for the duration of an in vivo scan. Although two-dimensional ultrasound imaging is useful for measuring local muscle deformations, assumptions must be made about global muscle shape changes, which could lead to errors in fully understanding the mechanical behaviour of muscle and its surrounding connective tissues, such as aponeurosis...

The core, or central musculoskeletal system of the torso, is essential for participating in sports and other physical activities. Core injuries are commonly encountered in athletes and active individuals. The importance of the midline pubic plate and rectus abdominis-adductor aponeurosis for core stability and function is discussed in the literature. This review article examines other important core injuries remote from the pubic symphysis, relevant clinical features, and preferred approaches to imaging. Several specific syndromes encountered in the core are reviewed...

PURPOSE: To investigate biomechanical properties of the levator aponeurosis. METHODS: Patients undergoing external levator resection for primary or revision correction of acquired ptosis were analyzed as primary and revision groups. Immediately postoperatively, the resected segments of the levator aponeurosis were stressed by adding sequential masses to the tissue. Specimen length was recorded at each stress level. Stress-strain diagrams were used to summarize how the tissue elongated in response to the external forces, because these diagrams correct for differences in specimen size...

Our understanding of in vivo Achilles tendon (AT) conditioning is limited to two-dimensional ultrasound measures of longitudinal deformation of the whole tendon. This study investigated the regional three-dimensional (3D) deformation of the AT during conditioning. Eighteen ATs were scanned using 3D freehand ultrasound during 10 successive 25 s submaximal (50%) voluntary isometric plantarflexion contractions. Longitudinal strain was assessed for the whole AT, aponeurosis, and free AT and transverse strain was assessed for the proximal-, mid-, and distal-portions of the free AT...

INTRODUCTION: Subgaleal hemorrhage is a rare but potentially fatal birth trauma. It is caused by rupture of the emissary veins (connections between the dural sinuses and scalp veins), followed by the accumulation of blood between the epicranial aponeurosis and the periosteum. Usually, it is associated with instrumental delivery (vacuum extraction, forceps delivery), but it may also occur spontaneously, suggesting the possibility of congenital bleeding disorder. CASE OUTLINE: A full term male neonate was born at 40 weeks gestation by spontaneous vaginal delivery, with birth weight of 3,700 g...

Putterman clamp, a muscle clamp, is commonly used in conjunctival müllerectomies. We report 3 cases of senile ptosis repaired with levator muscle resection using the Putterman clamp. The redundant levator aponeurosis was removed with electrocautery after clamping with the Putterman clamp. The levator muscle was refixed to the tarsus with three 4-0 Vicryl stitches after adjusting the height of the eyelid fissure. No intraoperative difficulties were encountered. Ecchymosis and edema were limited in the immediate postoperative period...

BACKGROUND Abnormal testicular descent can either be undescended or, less commonly, ectopic. Most undescended testes complete the course of descent by the first year of life only if these remain in the normal path of descent. The deviation of the testis may occur to an ectopic location during the transinguinal phase. Of the known ectopic sites, the anterior abdominal wall is the rarest site of testicular ectopia and to our knowledge only 3 cases of this nature have been reported in the available literature to date...
