Cremaster muscle thickening: the anatomic difference in men with testicular retraction due to hyperactive cremaster muscle reflex.

The objective was to assess whether men suffering from testicular retraction secondary to hyperactive cremaster muscle reflex have an anatomic difference in the thickness of the cremaster muscle in comparison to men who do not have retraction. From March 2021 to December 2021, 21 men underwent microsurgical subinguinal cremaster muscle release (MSCMR) on 33 spermatic cord units, as 12 of them had bilateral surgery, at Surgicare of South Austin Ambulatory Surgery Center in Austin, TX, USA. During that same time frame, 36 men underwent subinguinal microsurgical varicocele repair on 41 spermatic cord units, as 5 were bilateral for infertility. The thickness of cremaster muscles was measured by the operating surgeon in men undergoing MSCMR and varicocele repair. Comparison was made between the cremaster muscle thickness in men with testicular retraction due to a hyperactive cremaster muscle reflex undergoing MSCMR and the cremaster muscle thickness in men undergoing varicocele repair for infertility with no history of testicular retraction, which served as an anatomic control. The mean cremaster muscle thickness in men who underwent MSCMR was significantly greater than those undergoing varicocele repair for infertility, with a mean cremaster muscle thickness of 3.9 (standard deviation [s.d.]: 1.2) mm vs 1.0 (s.d.: 0.4) mm, respectively. Men with testicular retraction secondary to a hyperactive cremaster muscle reflex demonstrate thicker cremaster muscles than controls, those undergoing varicocele repair. An anatomic difference may be a beginning to understanding the pathology in men who struggle with testicular retraction.

Mucormicosis periostomal posoperatoria, a propósito de un caso / Mucormycosis periostomal: case report

Resumen Introducción: La mucormicosis en una enfermedad infrecuente y oportunista que afecta, principalmente, a pacientes inmunocomprometidos. Pocas veces se han reportado casos de afectación periostomal. Clínicamente puede ser confundida con otras patologías, pudiendo tener una evolución fulminante, por lo que un adecuado y pronto diagnóstico son necesarios para una instauración precoz del tratamiento. Caso Clínico: Se presenta el caso de una paciente de 62 años inmunocomprometida, que tras complicaciones quirúrgicas evoluciona con mucormicosis periostomal de la pared abdominal. A pesar de un tratamiento quirúrgico con múltiples resecciones de tejido asociado a antifúngico local y sistémico, la paciente fallece, concordante a la letalidad expresada en la literatura.

Introduction: Mucormycosis is a rare and opportunistic disease that mainly affects immunocompromised patients. Few cases of peristomal involvement have been reported. Clinically it can be confused with other pathologies and may have a fulminant evolution, so an adequate and prompt diagnosis is necessary for an early establishment of treatment. Clinical Case: We present the case of a 62-year-old immunocompromised patient who, after surgical complications, evolves with periostomal mucormycosis of the abdominal wall. Despite surgical treatment with multiple tissue resections, associated with local and systemic antifungal agents, the patient died, consistent with the lethality expressed in the literature.

Semiautomatic quantification of abdominal wall muscles deformations based on dynamic MRI image registration.

Quantitative analysis of abdominal organs motion and deformation is crucial to better understand biomechanical alterations undermining respiratory, digestive or perineal pathophysiology. In particular, biomechanical characterization of the antero-lateral abdominal wall is central in the diagnosis of abdominal muscle deficiency. Here, we present a dedicated semiautomatic dynamic MRI postprocessing method enabling the quantification of spatial and temporal deformations of the antero-lateral abdominal wall muscles. Ten healthy participants were imaged during a controlled breathing session at the L3-L4 disc level using real-time dynamic MRI at 3 T. A coarse feature-tracking step allowed the selection of the inhalation cycle of maximum abdominal excursion. Over this image series, the described method combines (1) a supervised 2D+t segmentation procedure of the abdominal wall muscles, (2) the quantification of muscle deformations based on masks registration, and (3) the mapping of deformations within muscle subzones leveraging a dedicated automatic parcellation. The supervised 2D+t segmentation (1) provided an accurate segmentation of the abdominal wall muscles throughout maximum inhalation with a 0.95 ± 0.03 Dice similarity coefficient (DSC) value and a 2.3 ± 0.7 mm Hausdorff distance value while requiring only manual segmentation of 20% of the data. The robustness of the deformation quantification (2) was indicated by high indices of correspondence between the registered source mask and the target mask (0.98 ± 0.01 DSC value and 2.1 ± 1.5 mm Hausdorff distance value). Parcellation (3) enabled the distinction of muscle substructures that are anatomically relevant but could not be distinguished based on image contrast. The present genuine postprocessing method provides a quantitative analytical frame that could be used in further studies for a better understanding of abdominal wall deformations in physiological and pathological situations.

Efficacy and Safety of a Surgeon-Performed Laparoscopic-Guided, 4-point Transversus Abdominis Plane Block: A retrospective review.

We performed a retrospective chart review from October 2017 to March 2019 to demonstrate the safety and efficacy of a surgeon-performed, laparoscopically guided, transversus abdominis plane (TAP) blocks for robot-assisted gynecologic procedures. A total of 116 patients who underwent robot-assisted gynecologic surgery, at 1 academic hospital, with administration of a 4-point TAP block were included. A 4-point TAP block was performed under laparoscopic visualization, by the same surgeon, after induction of anesthesia and immediately after placement of the laparoscope. Liposomal bupivacaine (20 mL) and 0.5% bupivacaine (20 mL) mixed with saline were used as the injectant. All information from the surgical admission and the postoperative follow-up were reviewed. Data were presented in our descriptive study. A total of 116 patients were included with a mean age of 40.6 years (19-80 years) and a mean body mass index of 30.6 kg/m2 (17.2-53.3 kg/m2). Of the patients, 70.7% were discharged to home on the day of surgery. Of the 29.3% of patients who were admitted, 20.6% were admitted because of pain control. Those who were admitted for pain control comprised 6.0% of the total of all study participants. There were no adverse events in our cohort and no readmissions because of pain control. A surgeon-performed TAP block, under laparoscopic visualization, is a safe and efficacious intervention to reduce postoperative pain and may add to a multimodal approach for enhanced recovery protocols.

Abdominal Ice after Laparoscopic Hysterectomy: A Randomized Controlled Trial.

STUDY OBJECTIVE: To assess the impact of abdominal ice packs on opioid use and pain control after laparoscopic hysterectomy DESIGN: Randomized controlled trial. SETTING: Academic tertiary care medical center. PATIENTS: Total of 142 adult women undergoing laparoscopic (either conventional or robotic) hysterectomy were randomized to control (n = 69) or intervention (n = 73). Exclusion criteria included preoperative opioid use, planned intensive care unit admission or same-day discharge, an incision ≥4 cm, and regional anesthesia use. INTERVENTIONS: Subjects in the intervention group had a large ice pack placed directly on the lower abdomen before leaving the operating room. The ice pack was maintained continuously for 12 hours postoperation, as desired thereafter until discharge, and continued use encouraged after discharge for up to 48 hours. MEASUREMENTS AND MAIN RESULTS: Total opioids administered postoperatively, while inpatient and after dismissal, were assessed in morphine milligram equivalents. Postoperative pain, as well as analgesia acceptability and side effects, were assessed using validated measures: Brief Pain Inventory and Overall Benefit of Analgesia Score. Median morphine milligram equivalent was lower in the intervention group than the controls from inpatient stay on the floor to completion of opioid use as an outpatient (22.5 vs 26.2) but was not statistically significant (p = .79). There was no significant difference between the groups in Brief Pain Inventory assessment of postoperative pain severity (p = .80) or pain interference (p = .36) or Overall Benefit of Analgesia Score total score (p = .88). Most patients in the intervention group were very satisfied with ice pack use (n = 51, 79.7%) and very likely to recommend it to friends or family (n = 54, 83.1%). There were no adverse events related to ice pack use. CONCLUSION: There was no significant difference in postoperative opioid use or pain assessment with ice pack use after laparoscopic hysterectomy. However, most of the subjects expressed high satisfaction specific to ice pack use and would recommend its use to others, suggesting potential desirability as adjunct therapy in postoperative pain control.

Prune-Belly syndrome, a rare case presentation in neonatology: about one case in Yaounde, Cameroon.

The Prune-Belly syndrome (PBS) is a rare pathology predominating in male infants, classically manifesting with the triad including aplasia of the abdominal wall muscles, dilatation of the urinary tract, and testicular abnormalities. We report and discuss the case of a full-term male newborn, in whom clinical examination at birth revealed abdominal wall muscle hypoplasia, cryptorchidism, urinary tract dilatation and renal failure. The diagnosis was made based on physical assessment, abdominal ultra-sonographic imaging, and blood sampling of urea and creatinine. For such cases, the recommended surgical management usually consists in a sequential surgical intervention including urinary tract reconstruction, abdominoplasty, and orchidopexy. However, these could not be practiced in due time in our patient, who died on the seventh day of life because of kidney failure. The prognosis of infants with Prune-Belly syndrome may be improved by quality antenatal follow-up, to enable the early diagnosis and preparation for prompt surgical intervention.

A new technique for the 3D reconstruction of the incisional hernia: A pilot study.

PURPOSE: This study aimed to accurately evaluate incisional hernias with a new three-dimensional (3D) reconstruction technology, proving surgeons more information for intuitive and accurate judgments about incisional hernia to minimize the perioperative complications and recurrence rate. METHOD: This was a pilot study using a new technique, 3D reconstruction, based on computed tomography (CT) scans to measure abdominal wall defect, herniary area, herniary volume, abdominal cavity volume, and the volume of transverse, oblique, and recti abdominis in three patients with incisional hernias. RESULTS: The 3D reconstruction technique made automated segmentation of the bony skeleton, skin, outer abdominal wall, vessel, and hernia sac. The hernia sac, abdominal muscles, and their anatomic relationship were clearly illustrated in 3D reconstruction images. Moreover, abdominal cavity volume; herniary diameter, area, and volume; and the volume of transverse, oblique, and recti muscles could be evaluated through 3D reconstruction images. Surgeons can also freely combine, rotate, scale, and move the 3D reconstruction mode, modify the name and transparency of the 3D reconstruction model, and observe the internal structure of the tissue and the size, shape, and location of the lesion from multiple angles for better and accurate judgments. CONCLUSION: The herniary diameter, area, and volume and the volume of transverse, oblique, and recti abdominis can be accurately calculated through this 3D reconstruction technology. A three-dimensional vision of the abdomen through this technology can objectively and quantitatively evaluate the situation of incisional hernia, providing a more realistic means for diagnosis and treatment of incisional hernias.

Use of Shear Wave Elastography to Quantify Abdominal Wall Muscular Properties in Patients With Incisional Hernia.

Shear wave elastography (SWE) is a potential modality that quantitatively measures the elasticity (shear wave speed [SWS]) of musculoskeletal structure. This SWS was bilaterally measured in the rectus abdominis (RA), external oblique (EO) muscle, internal oblique (IO) muscle and transversus abdominis (TrA) using SWE in 28 patients with incisional hernia and 14 healthy controls. The differences in muscle thickness for IO and TrA were significant between the two groups (p < 0.05). The SWS of RA, EO, IO and TrA was significantly higher in the incisional hernia patient group than in the healthy controls (p < 0.05). Significant differences were also observed between the upper and lower points in both groups (p < 0.05). The measurements of SWS help in evaluating the elastic properties of abdominal wall muscles, which could further aid in preparing treatment plans to improve muscle strength.

Sacral protuberance with cleft lip and palate: Prenatal presentation of 3MC syndrome.

3MC syndromes are rare heterogeneous autosomal recessive conditions previously designated as Mingarelli, Malpuech, Michels, and Carnevale syndromes, characterized by dysmorphic facial features, facial clefts, growth restriction, and intellectual disability. 3MC is secondary to mutations in the MASP1, MASP3, COLEC11, and COLEC10 genes. The number of patients with 3MC syndrome with known mutations in the COLEC11 or MASP1 is, to date, less than 50. At the time this case presented (2015), the only gene identified in Online Mendelian Inheritance in Man to be associated with 3MC syndrome was MASP1. We present, to the best of our knowledge, the first prenatal report of 3MC syndrome, secondary to a homozygous variant in MASP1. Fetal findings included bilateral cleft lip and palate, abnormality of the sacral spine, a right echogenic pelvic kidney, and brachycephaly. 3MC syndrome should be considered as part of the differential diagnosis when fetal ultrasound detects facial clefts and spinal defects, as the risk of recurrence is significant and a molecularly confirmed diagnosis allows for alternate reproductive options.

Postmortem Computed Tomography and Magnetic Resonance Imaging of an Abdominal Gunshot Wound.

The use of postmortem computed tomography (CT) has been described in many articles concerning gunshot injuries. Postmortem magnetic resonance imaging (MRI) for better assessment of soft tissue injuries has also been mentioned in the literature, albeit much less often. The use of postmortem MRI for abdominal gunshot wounds has not been previously presented in the literature. The present case report describes the findings of an abdominal gunshot wound detected by postmortem CT and MRI, followed by an autopsy. The main imaging findings on CT were a hyperdense ring at the entrance wound, which indicated the muzzle imprint mark, a hyperdense region beneath the skin, which was suggestive of combustion residue, gas cavities surrounding the bullet path, which might be related to the temporary cavity, and a fracture of the 13th rib on the left. Magnetic resonance imaging provided a clear depiction of defects in the muscle tissue and peritoneal fat, as well as an injury to the left kidney and a large volume of blood in the abdominal cavity. Computed tomography combined with MRI provided a descriptive presentation of the intracorporeal trajectory noninvasively. Autopsy confirmed the radiologic findings but additionally revealed further relevant findings, which were not detected radiologically, such as a duodenal perforation. Autopsy also detected subendocardial hemorrhages and shock kidney, which were consistent with severe blood loss.The imaging findings and their interpretations are discussed in this case report, as well as the role of CT and MRI in the assessment of abdominal gunshot wounds compared with autopsy.

Application of Acellular Tissue Matrix for Enhancement of Weak Abdominal Wall in Animal Model.

BACKGROUND: Abdominal wall weakness occurs when the strength of muscle decreases due to physiological reason or iatrogenic injury. However, the treatment of this disease is complicated. AIM: To study the therapeutic effect of acellular tissue matrix (ACTM), compared with the polypropylene mesh. METHODS: An abdominal wall weakness model was established in rabbits through motor nerves cutting. The polypropylene mesh and ACTM were implanted in the left and right abdomen sides, respectively. Mechanical testing of abdominal wall muscle and histology and scanning electron microscopy (SEM) evaluation of abdominal tissue explants were performed. RESULTS: In animal model establishment, the abdominal length of healthy and weakened abdominal wall was 17.0 ± 0.7 cm and 19.0 ± 1.2 cm, respectively (P=0.022), and the weak abdominal wall group showed a significant decrease of 1.116 ± 0.221 MPa in tensile stress (P=0.022), and the weak abdominal wall group showed a significant decrease of 1.116 ± 0.221 MPa in tensile stress (P=0.022), and the weak abdominal wall group showed a significant decrease of 1.116 ± 0.221 MPa in tensile stress (P=0.022), and the weak abdominal wall group showed a significant decrease of 1.116 ± 0.221 MPa in tensile stress (P=0.022), and the weak abdominal wall group showed a significant decrease of 1.116 ± 0.221 MPa in tensile stress (P=0.022), and the weak abdominal wall group showed a significant decrease of 1.116 ± 0.221 MPa in tensile stress (P=0.022), and the weak abdominal wall group showed a significant decrease of 1.116 ± 0.221 MPa in tensile stress (. CONCLUSION: The abdominal wall weakness model in rabbits was successfully established. ACTM is a promising biological material to be possibly further applied in clinical surgery in patients with abdominal wall weakness.

Abdominal wall sonography: a pictorial review.

The anterior abdominal wall, which is composed of three layers (skin and adipose tissues; the myofascial layer; and the deep layer, consisting of the transversalis fascia, preperitoneal fat, and the parietal peritoneum), has many functions: containment, support and protection for the intraperitoneal contents, and involvement in movement and breathing. While hernias are often encountered and well reviewed in the literature, the other abdominal wall pathologies are less commonly described. In this pictorial review, we briefly discuss the normal anatomy of the anterior abdominal wall, describe the normal ultrasonographic anatomy, and present a wide range of pathologic abnormalities beyond hernias. Sonography emerges as the diagnostic imaging of first choice for assessing abdominal wall disorders, thus representing a valuable tool for ensuring appropriate management and limiting functional impairment.

Ascites: an unusual presentation of eosinophilic gastroenteritis in a child.

Eosinophilic ascites, owing to serosal involvement, is a very rare manifestation of eosinophilic gastroenteritis in children, especially when it occurs with muscular involvement in the absence of mucosal disease, which may be confirmed by endoscopic ultrasonography. An 11-year-old girl, presenting with massive eosinophilic ascites and colicky abdominal pain with peripheral eosinophilia, raised IgE levels and positive skin prick test, had such investigation which confirmed the presence of muscle layer thickening of both stomach and small bowel. She responded well to steroids and montelukast.

Implementation of liposomal bupivacaine transversus abdominis plane blocks into the colorectal enhanced recovery after surgery protocol: a natural experiment.

BACKGROUND: Enhanced recovery after surgery (ERAS) programs are now standard of care for colorectal surgery. Efforts have been aimed at decreasing postoperative opioid consumption. The goal of this study is to evaluate the effect of liposomal bupivacaine transversus abdominis plane (TAP) blocks on opioid use and its downstream effect on rates of ileus and hospital length of stay (LOS). METHODS: We performed a retrospective pre- and postintervention time-trend analysis (2016-2018) of ERAS patients undergoing laparoscopic colorectal surgery at two academic medical centers within the same hospital system. The intervention was liposomal bupivacaine TAP blocks versus standard local infiltration with bupivacaine with a primary outcome of total morphine milligram equivalents (MME) administered within 72 h of surgery. Secondary outcomes included hospital LOS and rate of postoperative ileus. RESULTS: There were 556 patients included at the control hospital, and 384 patients were included at the treatment hospital. Patients at both hospitals were similar with regard to age, body mass index, comorbidities, and surgical indication. In an adjusted time-trend analysis, the treatment hospital was associated with a significant decrease in MME administered (- 15.9 mg, p = 0.04) and hospital LOS (- 0.8 days, p < 0.001). There was no significant decrease in the rate of ileus at the treatment hospital (- 6.9%, p = 0.08). CONCLUSIONS: In a time-trend analysis, the addition of liposomal bupivacaine TAP blocks into the ERAS protocol resulted in significantly reduced opioid use and shorter hospital LOS for patients undergoing surgery at the treatment hospital. Liposomal bupivacaine TAP blocks should be considered for inclusion in the standard ERAS protocol.

Left-sided Spigelian hernia with nontypical hernial sac content.

Spigelian hernia is one of the most uncommon hernia of the abdominal wall. Authors present 53 years old women with left sided spigelian hernia containing: caecum with appendix and ileum, which was an uncommon content of hernial sac. Past medical history of urinary bladder operation suggested postoperative hernia. However, the correct diagnosis was made during the operation. Hernioplasty was made with mesh onlay method. The postoperative course was unevenful.

Effects of neuromuscular electrical stimulation training on muscle size in collegiate track and field athletes.

The purpose of this study was to examine the effects of neuromuscular electrical stimulation training for 12 weeks on the abdominal muscle size in trained athletes. Male collegiate track and field athletes participated in the present study and were randomly allocated to either training or control groups. Eleven participants of the training group completed a 60-session training program over a 12-week period (23 min/session, 5 days/week) involving neuromuscular electrical stimulation (mostly 20 Hz) for the abdominal muscles in addition to their usual training for the own events. The participants of the control group (n = 13) continued their usual training. Before and after the intervention period, cross-sectional areas of the rectus abdominis and abdominal oblique muscles (the internal and external obliques and transversus abdominis) and subcutaneous fat thickness were measured with magnetic resonance and ultrasound imaging. There were no significant changes in cross-sectional area of the rectus abdominis or abdominal oblique muscles or in subcutaneous fat thickness in the training or control groups after the intervention period. The change in cross-sectional area of the rectus abdominis in each participant was not significantly correlated with pre-training cross-sectional area and neither was the mean value of fat thickness at pre- and post-training. These results suggest that low-frequency (20 Hz) neuromuscular electrical stimulation training for 12 weeks is ineffective in inducing hypertrophy of the abdominal muscles in trained athletes, even when they have a thin layer of subcutaneous fat.

Effects of Weighted Hula-Hooping Compared to Walking on Abdominal Fat, Trunk Muscularity, and Metabolic Parameters in Overweight Subjects: A Randomized Controlled Study.

BACKGROUND: Weighted hula-hoops have gained popularity, but whether they indeed reshape the trunk or have beneficial metabolic effects in overweight subjects is unknown. OBJECTIVES: To determine effects of hula-hooping and walking matched for energy expenditure on android fat %, trunk muscle mass, and metabolic parameters in a randomized cross-over study. DESIGN: We recruited 55 overweight nondiabetic subjects, who were randomized to hula-hooping (HULA) for 6 weeks using a 1.5-kg weighted hula-hoop followed by walking (WALK) for another 6 weeks or vice versa. The increments in energy expenditure were similar by HULA and WALK. Body composition (dual-energy X-ray absorptiometry) and metabolic parameters were measured at baseline and after HULA and WALK. The primary endpoint was the change in fat % in the android region. RESULTS: A total of 53subjects (waist 92 ± 1 cm, body mass index 28 ± 1 kg/m2) completed the study. Body weight changed similarly (-0.6 ± 0.2 vs. -0.5 ± 0.2 kg, nonsignificant; HULA vs. WALK). During the intervention the subjects hula-hooped on average 12.8 ± 0.5 min/day and walked 9,986 ± 376 steps/day. The % fat in the android region decreased significantly by HULA but not by WALK (between-group change p < 0.001). Trunk muscle mass increased more by HULA than by WALK (p < 0.05). Waist circumference decreased more by HULA than by WALK (-3.1 ± 0.3 cm vs. -0.7 ± 0.4 cm, p < 0.001; HULA vs. WALK). WALK but not HULA significantly lowered systolic blood pressure and increased HDL cholesterol while HULA significantly decreased LDL cholesterol. CONCLUSIONS: Hula-hooping with a weighted hula-hoop can be used to decrease abdominal fat % and increase trunk muscle mass in overweight subjects. Its LDL lowering effect resembles that described for resistance training.

Isolation and characterization of myogenic precursor cells from human cremaster muscle.

Human myogenic precursor cells have been isolated and expanded from a number of skeletal muscles, but alternative donor biopsy sites must be sought after in diseases where muscle damage is widespread. Biopsy sites must be relatively accessible, and the biopsied muscle dispensable. Here, we aimed to histologically characterize the cremaster muscle with regard number of satellite cells and regenerative fibres, and to isolate and characterize human cremaster muscle-derived stem/precursor cells in adult male donors with the objective of characterizing this muscle as a novel source of myogenic precursor cells. Cremaster muscle biopsies (or adjacent non-muscle tissue for negative controls; N = 19) were taken from male patients undergoing routine surgery for urogenital pathology. Myosphere cultures were derived and tested for their in vitro and in vivo myogenic differentiation and muscle regeneration capacities. Cremaster-derived myogenic precursor cells were maintained by myosphere culture and efficiently differentiated to myotubes in adhesion culture. Upon transplantation to an immunocompromised mouse model of cardiotoxin-induced acute muscle damage, human cremaster-derived myogenic precursor cells survived to the transplants and contributed to muscle regeneration. These precursors are a good candidate for cell therapy approaches of skeletal muscle. Due to their location and developmental origin, we propose that they might be best suited for regeneration of the rhabdosphincter in patients undergoing stress urinary incontinence after radical prostatectomy.

Reliability of sonography in the assessment of lumbar stabilizer muscles size in healthy subjects and patients with scoliosis.

OBJECTIVE: The purpose of the present study was to compare the reliability of sonography in the evaluation of abdominal and multifidus muscles size between healthy subjects and patients with scoliosis. METHODS: In this study, 20 healthy males and 20 male patients with scoliosis (20-50 years old) were recruited. Multifidus and abdominal muscles (transversus abdominis, internal and external oblique) size were assessed by sonography. Three images were recorded; the first and second images were taken on the same day with an hour interval to evaluate within-day reliability, and the third image was taken one-week later to assess between-day reliability. RESULTS: Intraclass correlation coefficient (ICC = 0.82-0.91) demonstrated high within-day reliability of sonography in the assessment of abdominal muscle thickness in both groups. In addition, high between-day reliability was observed for these muscles in both healthy and patient groups (ICC = 0.80-0.89). Within-day and also between-day reliability of multifidus muscle were shown to be high in the healthy group (ICC = 0.81-0.88) and the patient group (ICC = 0.78-0.85). Overall, within-day reliability was higher than between-day reliability and also the reliability of sonography in healthy subjects was greater than of those suffering from scoliosis. CONCLUSIONS: According to the results, sonography was shown to be a highly reliable imaging technique for assessment of abdominal and multifidus muscle size in healthy males and those suffering from scoliosis.
