BACKGROUND Lateral ulnar collateral ligament (LUCL) reconstruction requires proper understanding and identification of anatomic structures about the lateral elbow. The insertion site of the LUCL is based on the supinator tubercle. PURPOSE To characterize the supinator tubercle relative to other surrounding anatomic landmarks. STUDY DESIGN Descriptive laboratory study. METHODS Computed tom...

Background and Objective: Pain is one of the most common complications after thyroidectomy. Opioid administration can overcome this complication, however, it has some side effects, including nausea and vomiting. So, the use of local anesthetic instead of opioids is a good alternative. This study was conducted to evaluate and compare the effect of ultrasound-guided superficial cervical plexus bl...

1209 November 2013 T transversus abdominis (TA) plane regional anesthesia block is a well-described and effective method for reducing pain from lower abdominal surgeries. Successful ultrasound-guided TA plane block is dependent on correct recognition of muscle borders within the anterolateral abdominal wall.1 This wall is composed of three distinct muscle layers from the external oblique (eO), ...

BACKGROUND AND PURPOSE Injection therapies play a major role in the treatment of lower back pain and are to date performed mainly under CT or fluoroscopic guidance. The benefits of US-guided instillation procedures have been shown in many studies. We conducted this study to simplify an US-guided approach to the lumbar spinal nerves and to assess the feasibility and preliminary accuracy by means...

objectives: this study aimed to evaluate the location and characteristics of mental foramen, anterior loop and mandibular incisive canal using cone beam computed tomography (cbct). materials and methods: this retrospective cross-sectional study evaluated 200 mandibular cbct scans for the location of mental foramen, anterior loop prevalence and mandibular incisive canal visibility, its mean leng...

In 1989 Clark et al, 1 in a landmark article, used multivari-ate analysis and logistic regression to generate a model predicting survival in stage I primary malignant melanoma. They examined 23 attributes and found that, in addition to tumor thickness, 5, including mitotic rate, presence of tumor-infiltrating lymphocytes, anatomic site of the lesion, sex of the patient, and histologic evidence ...

An automatic mechanism that gives verbal navigation instructions to pedestrians in situ needs to take into account a number of factors. Besides giving the instruction at the right time and place, the information needs to be as unambiguous as possible for the user to both choose the correct path and be confident in doing so. Humans make extensive use of landmarks when describing the way to other...

Background The cystic lymph node (CLN) represents an anatomic safety marker and a surrogate of technique during laparoscopic cholecystectomy (LC). We aim to demonstrate the value CLN in comparison critical view (CVS) study effects increasing difficulty on 2 approaches. Methods A prospective consecutive LC was conducted. Patient demographics, type admission, clinical presentation, operative grad...
