On the biological mechanics and energetics of the hip joint muscle-tendon system assisted by passive hip exoskeleton.

Bioinspir Biomim 2018 Dec 4;14(1):016012. Epub 2018 Dec 4.

The State Key Laboratory of Digital Manufacturing Equipment and Technology, School of Mechanical Science and Engineering, Huazhong University of Science and Technology, Wuhan 430074, People's Republic of China.

Passive exoskeletons have potential advantages in reducing metabolic energy cost. We consider a passive elastic exoskeleton (peEXO) providing hip flexion moment to assist hip flexors during walking, our goal is to use a biomechanical model to explore the biological mechanics and energetics of the hip joint muscle-tendon-exotendon system for obtaining the optimum stiffness of this peEXO at the muscle-level. Based on our developed hip musculoskeletal model capable of replicating human-like behaviors, the hip peEXO is firstly abstracted as a spring (i. Read More

Hip and Core Muscle Injuries in Soccer.

Am J Orthop (Belle Mead NJ) 2018 Oct;47(10)

Riverside University Health System, 26520 Cactus Ave, Moreno Valley, CA 92555, USA. Email:

Soccer is the most popular sport in the world and has the fourth highest number of sports injuries. Hip and groin injuries account for 14% of soccer injuries and can be difficult to recognize and treat as they often require a high level of suspicion and advanced imaging. Groin pain can be separated into 3 categories: (1) defined clinical entities for groin pain (adductor-related, iliopsoas-related, inguinal-related [sports hernias/athletic pubalgia], and pubic-related groin pain), (2) hip-related groin pain (hip morphologic abnormalities, labral tears, and chondral injuries), and (3) other causes of groin pain.

Laparoscopic cholecystectomy is a surgical treatment for acute cholecystitis or symptomatic cholelithiasis. One potential complication, the spillage of gallstones into the peritoneal cavity, can form a nidus for infection and may be associated with hepatic, retroperitoneal, thoracic, and abdominal wall abscesses. We report a case of a patient presenting with a right iliopsoas abscess and an infected right hip prosthesis status postlaparoscopic cholecystectomy. Read More

Background: A devasting course of Iliopsoas Muscle (IPM) abscess remains a challenging therapeutic problem.

Methods: A 69-year-old polymorbid male had a history of multiple carcinomas and presented with advanced stage of septic shock due to a right IPM abscess which communicated with the right hip joint and subsequently led to septic hip arthritis accompanied with post-infectious right gluteal deep soft tissue necroses. Management of surgical treatment included abscess revision, coverage with the use of Long Head Biceps Femoris Muscle (LHBFM) 180° turnover flap, and creating a Girdlestone resection-arthroplasty.

Endovascular Embolization of Spontaneous Iliopsoas Hematoma: First Experience with Squidperi.

Case Rep Radiol 2018 27;2018:4694931. Epub 2018 Feb 27.

ASST Santi Paolo and Carlo, San Carlo Borromeo Hospital, Department of Diagnostic Science, Radiology and Interventional Radiology Unit, Via Pio II 3, 20153 Milano, Italy.

A 79-year-old man, suffering from atrial fibrillation and on anticoagulation therapy, was admitted at the emergency department of our institution because of a worsening respiratory insufficiency. After a diagnostic work-up, he was found to suffer from pneumonia, and antibiotic therapy was settled. He was kept under observation for his pulmonary conditions but, within a week, he developed a spontaneous iliopsoas hematoma, due to a sudden dysregulation of anticoagulation therapy subsequent to new in-hospital treatments.

Ilioinguinal Approach: Indication and Technique.

J Orthop Trauma 2018 Aug;32 Suppl 1:S12-S13

Department of Trauma, Hand and Reconstructive Surgery, University Medical Center Hamburg-Eppendorf, Martinistraße, Hamburg, Germany.

This video on the ilioinguinal approach presents its indications and techniques for the operative treatment of acetabular fractures. The principle of the ilioinguinal approach is to work through 3 different windows. The lateral window gives access to the pelvic bone from the sacroiliac joint to the lateral border of the iliopsoas muscle, the middle window accesses the medial border of the iliopsoas muscle to the femoral artery, and the medial window allows for control of the anterior pelvic ring medially from the femoral vein to the symphysis pubis.

Identification of potential markers of fatal hypothermia by a body temperature-dependent gene expression assay.

Int J Legal Med 2018 Jun 29. Epub 2018 Jun 29.

Division of Forensic Pathology and Science, Unit of Social Medicine, Course of Medical and Dental Sciences, Graduate School of Biomedical Sciences, Nagasaki University School of Medicine, 1-12-4 Sakamoto, Nagasaki, Nagasaki, 852-8523, Japan.

Diagnosis of fatal hypothermia is considered to be difficult in forensic practice and even if findings due to cold exposure are evident, cold exposure is not necessarily a direct cause of death. Identification of useful molecular markers for the diagnosis of fatal hypothermia has not been successful. In this study, to identify novel molecular markers that inform the diagnosis of fatal hypothermia, we focused on skeletal muscle, which plays a role in cold-induced thermogenesis in mammals.

Perforated caecal carcinoma masquerading as lower limb necrotising fasciitis: lessons learnt.

BMJ Case Rep 2018 Jun 27;2018. Epub 2018 Jun 27.

Plastic Surgery and Burns, University Hospitals Coventry and Warwickshire NHS Trust, Coventry, UK.

A 69-year-old man was admitted with non-resolving right leg cellulitis. Subsequent skin changes over the calf and discharging pus suggested necrotising fasciitis. After several wound debridements of the leg and imaging, the patient was found to have an iliopsoas abscess due to a metastatic perforated caecal tumour extending along the medial thigh to the calf.

Relationship between knee alignment in asymptomatic subjects and flexibility of the main muscles that are functionally related to the knee.

J Int Med Res 2018 Aug 25;46(8):3065-3077. Epub 2018 Jun 25.

1 Faculty of Health Sciences, Physiotherapy Research Unit, University of Zaragoza, C/Domingo Miral s/n, Zaragoza, Spain.

Objective To assess the relationship between static frontal knee alignment in asymptomatic subjects and flexibility of the main muscles functionally related to the knee. Methods A descriptive cross-sectional study was performed in 33 healthy adults (19-31 years). The frontal knee angle (valgus/varus angle) was measured by photogrammetry and it was measured in the lateral side. Read More
