A trigger digit is relatively uncommon in adolescents and often has a different etiology in that age group vs adults. In the pediatric population, trigger digits frequently arise from a variety of underlying anatomic situations, including thickening of the flexor digitorum superficialis or flexor digitorum profundus tendons, an abnormal relationship between the flexor digitorum superficialis and flexor digitorum profundus tendons, a proximal flexor digitorum superficialis decussation, or constriction of the pulleys...

PURPOSE: To investigate the effects of performing a previously described algorithmic levator resection for involutional ptosis with a blepharoplasty instead of through a small incision. METHODS: Eyelids with involutional ptosis and normal levator function were included in the study. An upper blepharoplasty was performed first. An external levator resection was then performed based on a described technique involving 2 mm resection of aponeurosis for 1 mm of desired lift, consistent tension on the aponeurosis between surgical cases, and standardized suture placement...

Although overexpression of genes encoding detoxification enzymes is a well-known mechanism of pesticide resistance of mites, the regulators involved in this process are still illiterate. Previous studies in our laboratory demonstrated that the overexpression of six P450 genes contributes to fenpropathrin resistance in T. cinnabarinus. In this study, six transcription factor genes that likely regulate the expression of P450 genes were identified and characterized. Quantitative PCR (qPCR) analysis showed that three transcription factor genes were highly expressed in a fenpropathrin-resistant (FeR) strain of T...

Importance: External surgical treatment of involutional ptosis with normal levator function is challenging owing to lack of an established algorithm. Developing an algorithm-based technique could improve postoperative results while limiting intraoperative inefficiencies. Objective: To investigate the postoperative success of an algorithmic external levator aponeurosis resection technique for aponeurotic ptosis with good levator function. Design, Setting, and Participants: This retrospective cohort study included patients with involutional ptosis and normal levator function who were treated from July 1, 2015, through November 30, 2016, at a private ophthalmic plastic surgery clinic...

PURPOSE: The transition muscle between the palatopharyngeus (PP) and the superior constrictor of the pharynx (SCP) encircles the pharyngeal isthmus from behind and is designated as the palatopharyngeal sphincter (PPS). The PPS is inferred to play important roles for velopharyngeal closure, but its existence remains controversial and its roles have been regarded as being played by the SCP. The present study aimed to clarify the anatomical status and functional implications of the PPS. MATERIALS AND METHODS: Macroscopic and microscopic examinations were performed on 39 and 4 cadavers, respectively...

The cubital region of the arm is a common site for recording blood pressure, taking blood for analysis and administering intravenous therapy and blood transfusions. During the routine dissection of a 70-year-old male cadaver at the Kasturba Medical College, Manipal, Karnataka, India, in 2015, it was observed that the aponeurotic insertion of the biceps brachii muscle divided into two slips. The medial slip fused normally with the deep fascia of the forearm, while flexor carpi radialis muscle fibres originated from the lateral slip...

Review of the English orthopaedic literature reveals no prior report of endoscopic repair of rectus abdominis tears and/or prepubic aponeurosis detachment. This technical report describes endoscopic reattachment of an avulsed prepubic aponeurosis and endoscopic repair of a vertical rectus abdominis tear immediately after endoscopic pubic symphysectomy for coexistent recalcitrant osteitis pubis as a single-stage outpatient surgery. Endoscopic rectus abdominis repair and prepubic aponeurosis repair are feasible surgeries that complement endoscopic pubic symphysectomy for patients with concurrent osteitis pubis and expand the less invasive options for patients with athletic pubalgia...

REVIEW
Tsuyoshi Sato, Tetsuya Yoda
Limited mouth opening is a common health problem that interferes with eating, makes examination of the oral cavity difficult, and may increase the mortality rate during emergency intubation. Here we introduce a disease designated as masticatory muscle tendon-aponeurosis hyperplasia, which is a new clinical condition of limited mouth opening. Most oral surgeons and dentists are still unaware of this disease condition, thus increasing the risk of incorrect diagnosis as some other disease, such as temporomandibular joint disorder...

Cortical desmoids are self-limiting fibro-osseous lesions commonly occurring at the medial supracondylar femur in active adolescents, at either the origin of the medial head of the gastrocnemius or at the insertion of the adductor magnus aponeurosis. Less commonly, in a similar demographic, cortical desmoids may occur in the proximal humerus medially at the insertion of the pectoralis major muscle or laterally at the insertion of the deltoid. The radiographic appearance of the proximal humerus cortical desmoid has been described previously, but not the MRI appearance...

The exact knowledge of the anatomy of the fibrous skeleton of the hand is an absolute prerequisite for any treatment of Dupuytren's disease. The fibrous skeleton does not only include the palmar aponeurosis, but also numerous retinacula cutis, which are not found in current anatomy books. Here, eponyms facilitate the otherwise difficult and over-pronounced names of the fiber systems. Skoog, Legueu and Juvara, Gosset, Grapow, Grayson, Cleland, Thomine, and Barton are the most important. This systematic review of the fibers and strands is designed to help reduce iatrogenic complications...

INTRODUCTION: In the precise localization of ulnar neuropathy at the elbow (UNE) we have noted discrepancies between electrodiagnostic (EDx) and ultrasonographic (US) findings. We aimed to explore the relationship between the 2 methods. METHODS: Four study-blind examiners took a history and performed neurologic, EDx, and US examinations of a group of prospectively recruited patients with UNE. They assessed the relationship between ulnar nerve cross-sectional area (CSA) and motor nerve conduction velocity (MNCV)...

The Hoffmann reflex (H reflex) is extensively used to investigate the spinal motor neuron excitability in healthy and pathological subjects. Obtaining a representative and robust amplitude estimation of the H reflex is of marked relevance in clinical as well as in research applications. As for the motor responses, this issue is strictly related to the electrode positioning, especially for large, pinnate muscles such as the triceps surae. In this study we investigated the effect of electrode position on soleus H-reflex amplitude...

Rupture of the collateral ligaments in the metacarpophalangeal (MCP) joint of a finger is less common than in the thumb. Literature about these lesions is sparse but the number of chronic injuries reported underlies the number of cases overlooked by physicians at the first visit. A Stener-like lesion is characterized by interposition of the extensor hood or the sagittal band between the torn collateral ligament of the MCP joint of a finger and its insertion. It was originally described as interposition of the adductor aponeurosis of the thumb...
