Adductors

This study aimed to investigate the clinical viability of utilizing the flexor hallucis brevis as an alternative site for neuromuscular monitoring compared to the conventional adductor pollicis. Patients were recruited from three medical centers. Cis-atracurium was administered, and two monitors were employed independently to assess neuromuscular blockade of the adductor pollicis and the ipsilateral flexor hallucis brevis, following a train of four (TOF) pattern until TOF ratios exceeded 0.9 or until the conclusion of surgery...

BACKGROUND: Combining osteotomies and soft tissue procedures is believed to reduce sesamoids in their anatomical position and maintain long-term correction when treating hallux valgus deformity. This study determines if a radiologic association exists between a radiolucent sign and a full percutaneous adductor tendon release (PATR), including a cadaveric study and a consecutive case series. Another aim was to determine the intra- and interobserver reliability of these observations. METHODS: A prospective observational study was made between 2018 and 2019...

INTRODUCTION: Lower Cross Syndrome (LCS) is a prevalent condition that manifests as muscular tension due to the asymmetry in the strength of the lower extremity muscles. This imbalance could be due to the tautness of the iliopsoas, rectus femoris, tensor fascia latae, adductor group, gastrocnemius, and soleus muscles. LCS causes a postural imbalance in the individual, which triggers low back pain (LBP). When LCS is present alongside LBP, may cause the upper body to sway more in the transverse plane and at the lumbar level, making walking and termination of gait (GT) more difficult...

INTRODUCTION: Impaired laryngopharyngeal sensation has been implicated in obstructive sleep apnea (OSA) and may play an important pathophysiological role. We evaluated sensory function in OSA by examining the laryngeal adductor reflex (LAR) response rate and temporal profile to tactile stimulation. METHODS: Laryngeal sensation testing was performed in awake adults with and without diagnosed OSA by stimulating the medial aryepiglottic fold or arytenoid using 30-mm 5-0 and 4-0 nylon Cheung-Bearelly monofilaments...

INTRODUCTION: Core stability is crucial for preventing and rehabilitating lumbar spine injuries. An external focus instruction using a paper balloon is an effective way to activate the trunk muscles. However, the degree of trunk and lower extremity muscle activation during single leg stance with external focus instruction using a paper balloon is unknown. This study aimed to investigate the core muscle involving activity in the trunk and lower extremities on both the support and non-support sides with or without using external focus instruction using a paper balloon during isometric single-leg stance...

PURPOSE: There is a need for an easily measurable and reliable surrogate marker for physical frailty. This study aims to investigate the predictive capacity of adductor pollicis muscle thickness (AMPT), which can be easily measured externally and minimally influenced by subcutaneous adipose tissue, for physical frailty. METHODS: A total of 589 patients (16.3% physically frail, 54.7% pre-frail, 29% robust) were included. Comprehensive geriatric assessments and anthropometric measurements of the patients were performed...

Trace amine-associated receptors (TAARs) are a class of G protein-coupled receptors, playing an immunomodulatory function in the neuroinflammatory responses. In the present study, a TAAR homologue with a 7tm_classA_rhodopsin-like domain (designated as CgTAAR1L) was identified in oyster Crassostrea gigas. The abundant CgTAAR1L transcripts were detected in visceral ganglia and haemocytes compared to other tissues, which were 55.35-fold and 32.95-fold (p < 0.01) of those in adductor muscle, respectively...

Adolescent childbirth is associated with worse physical function over the long-term. Differential loss of muscle strength during pregnancy and postpartum for adolescents compared to adults may be one explanation for this, but research examining these differences is lacking. The objective of this study as to assess hand grip strength and hip adduction muscle strength in adolescents and adults during pregnancy and postpartum. A prospective cohort study was carried out with adolescent (13 to 18 years) and adult (23 to 28 years) primigravid women...

OBJECTIVE: To describe the prevalence, incidence, and burden of groin injuries in the Norwegian women's premier football league and to describe their clinical and imaging characteristics. METHODS: During the 2020 and 2021 seasons, players in the Norwegian women's premier league reported groin injuries weekly, using the Oslo Sports Trauma Research Centre Questionnaire on Health Problems (OSTRC-H2). We calculated weekly prevalence, incidence, and burden of groin injuries...

BACKGROUND: In National Collegiate Athletic Association (NCAA) soccer athletes, men have higher rates of hip and groin strains, whereas women have higher rates of knee ligament injuries. Strength imbalances of the hip and thigh, specifically in agonist-antagonist muscles, are known risk factors for these injuries. OBJECTIVE: To perform hip and thigh strength assessments in NCAA soccer players to evaluate for differences between genders and correlations with gender-specific injury patterns...

The laryngeal adductor reflex (LAR) is a brainstem reflex that closes the vocal fold and constitutes a new method for continuously monitoring the vagus and laryngeal nerves during different surgeries. Previous reports concluded that topical lidocaine in spray inhibited LAR responses. However, topical anesthesia in the upper airway may be necessary in awake intubation. We present six patients who underwent neck endocrine surgery due to an intrathoracic goiter that compromised the airway. Before awake intubation, a nebulization of lidocaine 5% was applied for at least 10 min...

OBJECTIVE: To evaluate functional outcomes of surgery of spastic hip adductor muscles (obturator neurotomy with or without adductor longus tenotomy) in ambulatory and non-ambulatory patients, using preoperatively defined personalized goals. DESIGN: Retrospective observational descriptive study. PATIENTS: Twenty-three patients with adductor spasticity who underwent obturator neurotomy between May 2016 and May 2021 at the Clinique des Cèdres, Cornebarrieu, France, were included...

PURPOSE OF REVIEW: Patients often experience a significant degree of knee pain following total knee replacement (TKR). To alleviate this pain, nerve blocks may be performed such as the adductor canal block (ACB). However, ACBs are unable to relieve pain originating from the posterior region of the knee. A new type of nerve block known as the IPACK block may be used in conjunction with ACBs as it is designed to inhibit nerve branches innervating this area. In this article, we examine the rationale behind the IPACK procedure, how it is performed, and clinical trials examining its efficacy...

The femoral epicondyle is an anatomical bony landmark essential for surgeons and anatomists, but there are discrepancies between the two fields when using this term. In current orthopedic surgery, it commonly denotes the small bony prominence of the femoral condyle. Given the derivation, "epicondyle" should be a region projecting laterally from the articular surface rather than a point. These discrepancies in usage are found not only between the fields but also in the literature. This article reviews the narrative definition of "epicondyle of the femur" in surgery and the evolution of the term in anatomy...

BACKGROUND: Split phenomena (SP) are characterized by patterns of differential muscle wasting and atrophy, which are highly prevalent in amyotrophic lateral sclerosis (ALS) patients. Several neurophysiological indicators, including the split-hand index (SHI), split-leg index (SLI), and split-elbow index (SEI), have been proposed to assess SP. Nevertheless, their cutoff values and the impact of age and sex on these measures remain unclear. METHODS: We prospectively collected neurophysiological data from 300 healthy adult subjects...

Ultrasound (US) technology has significantly expanded the spectrum of regional anesthesiological procedures in recent years. Abdominal wall blocks are becoming an increasingly integral part of a multimodal postoperative pain concept after abdominal surgery, gynecological or urological interventions. Thoracic epidural analgesia remains the gold standard for extensive surgery. The requirement for rapid postoperative mobilization and discharge after lower extremity surgery has led to the abandonment of neuroaxial or plexus blocks in favor of selective, peripheral blocks such as the PENG block or adductor canal block...

Sarcolemmal membrane excitability is often evaluated by considering the peak-to-peak amplitude of the compound muscle action potential (M-wave). However, the first and second M-wave phases represent distinct properties of the muscle action potential, which are differentially affected by sarcolemma properties and other factors such as muscle architecture. Contrasting with previous studies in which voluntary contractions have been used to induce muscle fatigue, we employed repeated electrically-induced tetanic contractions of the adductor pollicis muscle and assessed the kinetics of M-wave properties during the course of the contractions...

BACKGROUND: Soft tissue plays an important role in stabilizing the hinge point for osteotomy around the knee. However, insufficient data are available on the anatomic features of the soft tissue around the hinge position for lateral closing-wedge distal femoral osteotomy (LCWDFO). PURPOSE: To (1) anatomically analyze the soft tissue around the hinge position for LCWDFO, (2) histologically analyze the soft tissue based on the anatomic analysis results, and (3) radiologically define the appropriate hinge point to prevent unstable hinge fracture based on the results of the anatomic and histological analyses...

TOPIC IMPORTANCE: Laryngeal dysfunction as a cause of chronic refractory cough (CRC) and episodic dyspnea is often missed which results in unnecessary testing and delays in diagnosis. Understanding laryngeal roles in breathing and airway protection can help to appreciate the propensity to laryngeal dysfunction with aging, chronic lung disease and sleep apnea. REVIEW FINDINGS: The human larynx is a complex muscular structure that undertakes multiple roles of breathing, vocalization, coughing and swallowing...

OBJECTIVES: This study aimed to compare the analgesic effects of continuous femoral nerve block (FNB), femoral triangle block (FTB), and adductor canal block (ACB) following total knee arthroplasty (TKA). The goal was to identify the most effective nerve block technique among these three. METHODS: Patients undergoing TKA were randomly assigned to one of three groups: FNB, FTB, or ACB. Nerve blocks were administered preoperatively, with catheters placed for patient-controlled nerve analgesia (PCNA)...
