Index Finger Flexor Digitorum Profundus Function Deficit after Shoulder Arthroscopy Treated by Neurolysis: A Case Report.

A 60-year-old woman presented functional deficit of the index finger flexor digitorum profundus (FDP) tendon after shoulder arthroscopic rotator cuff repair. As no recovery was observed for 10 months, we conducted an operative exploration of the median nerve and the anterior interosseous nerve, followed by an external neurolysis. The patient recovered FDP function 4.

Differences in time-to-fusion based on "absence of peri-graft radiolucency" and "trabecular bone bridging" criteria after transforaminal lumbar interbody fusion in patients with low and normal bone density.

Objective: To investigate the difference in time-to-fusion between two sets of interbody fusion criteria (absence of peri-graft radiolucency vs. trabecular bone bridging), and to determine the effect of osteoporosis on time-to-fusion.

Materials And Methods: This retrospective study enrolled 79 patients treated for degenerative disease with one-level transforaminal lumbar interbody fusion from February 2012 to December 2018, and who had both pre- and post-operative CTs.

Psoas muscle measurement as a predictor of recurrent lumbar disc herniation: A retrospective blind study.

AbstractParaspinal (erector spinae and multifidus) and psoas muscles contribute to spinal stability, but no study has yet examined the relationship between muscle mass and recurrent lumbar disc herniation (rLDH). The purpose of this study was to investigate the effect of psoas and paraspinal muscle mass on recurrent Lumbar disc herniation (LDH). This retrospective study included 49 patients with LDH (22 men, 27 women; mean age: 59.

Explainable machine learning model to predict refeeding hypophosphatemia.

Background & Aims: Refeeding syndrome (RFS) is a disease that occurs when feeding is restarted and metabolism changes from catabolic to anabolic status. RFS can manifest variously, ranging from asymptomatic to fatal, therefore it may easily be overlooked. RFS prediction using explainable machine learning can improve diagnosis and treatment.

Spinal subdural hematoma: A report of 3 cases related to antiplatelet agent use and traumatic compression fracture.

Spinal subdural hematoma is a rare condition presenting with symptoms of back pain and neurologic deficits. The etiology is largely idiopathic, followed by anti-coagulant use and vascular malformation. Traumatic subdural hematomas associated with compression fractures are rare, with only a few old case reports.

Predicting Bone Marrow Edema and Fracture Age in Vertebral Fragility Fractures Using MDCT.

The purpose of this study was to evaluate whether CT features can predict bone marrow edema (BME) on MRI and fracture age in vertebral fragility fractures. A total of 189 thoracolumbar compression fractures in 103 patients (14 men, 89 women; mean age, 76 years) imaged with both spine CT and MRI were retrospectively included. The presence and extent of BME were assessed on MRI to divide fractures into those with and without BME.

Axillary sparganosis, changes in ultrasound images over six months: A case report.

Sparganosis is an infestation caused by a tapeworm belonging to the genus Spirometra. The typical radiologic findings of sparganosis describe elongated, folded, band or tubular, hypoechoic structures with surrounding increased echogenicity in ultrasonography. These imaging features have been highly consistent with pathology results.

Paraspinal Lean Muscle Mass Measurement Using Spine MRI as a Predictor of Adjacent Segment Disease After Lumbar Fusion: A Propensity Score-Matched Case-Control Analysis.

The purpose of this study was to compare paraspinal muscle mass between patients with and without adjacent segment disease (ASD) after lumbar fusion. Fifty patients with ASD (mean age, 61.4 years; ratio of male to female patients: 13:37; mean body mass index [BMI; weight in kilograms divided by the square of height in meters], 25.

Metal Artifact Reduction in Virtual Monoenergetic Spectral Dual-Energy CT of Patients With Metallic Orthopedic Implants in the Distal Radius.

Objective: The purpose of this study was to evaluate the image quality of virtual monoenergetic images obtained from dual-layer-detector spectral CT of patients with metallic orthopedic implants of the distal radius.

Materials And Methods: A retrospective analysis was performed between April 2016 and January 2017. Forty-three consecutively registered patients (33 women, 10 men; mean age, 50.

MRI of Cuboid Pulley Lesion.

Objective: The aim of this study was to describe cuboid pulley lesions and associated abnormalities on the basis of clinical findings and the results of MRI examinations of the ankle.

Materials And Methods: A retrospective search was performed to identify patients who had a cuboid pulley lesion during a 10-year period. A cuboid pulley lesion was defined as bone marrow edema in the lateroplantar ridge of the cuboid that was shown to be wrapped by the peroneus longus tendon on MRI of the ankle.

CT features of hepatic metastases from hepatoid adenocarcinoma.

Purpose: The purpose of this study was to report the imaging presentation of hepatic metastases from hepatoid adenocarcinoma (HAC).

Methods: We retrospectively identified 11 patients (10 men and 1 woman; median age 66) with HAC liver metastasis who underwent contrast-enhanced computed tomography (CT) which included arterial phase and portal venous phase. Two radiologists analyzed the imaging parameters, which included the enhancement pattern on arterial and portal phase images, necrosis, venous thrombi, and overall imaging diagnosis, and arrived at a consensus.

Effects of intraoperative inhaled iloprost on primary graft dysfunction after lung transplantation: A retrospective single center study.

Design: Inhaled iloprost was known to alleviate ischemic-reperfusion lung injury. We investigated whether intraoperative inhaled iloprost can prevent the development of primary graft dysfunction after lung transplantation. Data for a consecutive series of patients who underwent lung transplantation with extracorporeal membrane oxygenation were retrieved.

Plug-Assisted Retrograde Transvenous Obliteration for the Treatment of Gastric Variceal Hemorrhage.

Objective: To evaluate the feasibility, safety, and clinical outcomes of plug-assisted retrograde transvenous obliteration (PARTO) to treat gastric variceal hemorrhage in patients with portal hypertension.

Materials And Methods: From May 2012 to June 2014, 19 patients (11 men and 8 women, median age; 61, with history of gastric variceal hemorrhage; 17, active bleeding; 2) who underwent PARTO using a vascular plug and a gelfoam pledget were retrospectively analyzed. Clinical and laboratory data were examined to evaluate primary (technical and clinical success, complications) and secondary (worsening of esophageal varix [EV], change in liver function) end points.

Prepubertal Testicular Teratomas and Epidermoid Cysts: Comparison of Clinical and Sonographic Features.

Objectives: To evaluate clinical and sonographic features of testicular teratomas and epidermoid cysts in children and to assess differential points of immature teratomas from benign counterparts.

Methods: We retrospectively reviewed testicular teratomas and epidermoid cysts in children. Age at surgery, α-fetoprotein (AFP) level, and sonographic findings, including components (mainly cystic, mainly solid, or mixed), presence of calcification, and size, were reviewed.

Choledochal cyst rupture with an intrahepatic pseudocyst mimicking hepatic mesenchymal hamartoma in an infant.

Spontaneous choledochal cyst rupture and consequent biliary peritonitis are rare in children. Here, we report a unique case of intrahepatic bile duct rupture of choledochal cyst type IV that resulted in loculated biliary peritonitis with an intrahepatic pseudocyst mimicking a hepatic mesenchymal hamartoma in a 3-month-old boy. Magnetic resonance cholangiopancreatography can help differentiate these conditions.
