PURPOSE: The coracoacromial ligament (CAL) presents with variable morphology and plays a significant role in the development of subacromial impingement syndrome. Sectioning the CAL has been suggested to relieve impingement of the rotator cuff. The aim of the current study was to investigate the CAL attachment in relation with ligament morphology. MATERIALS AND METHODS: The CAL was investigated in 220 cadaveric shoulders from 58 males and 59 females, with a median age of 82 years (range 53-102 years)...

PURPOSE: Atrial fibrillation (AF) is an arrhythmia which affects as many as 2.7 million Americans. AF should be treated, because it can lead to a four-to-fivefold increased risk of experiencing a stroke. The American College of Cardiology/American Heart Association guidelines for the treatment of drug refractory and symptomatic paroxysmal AF denote catheter ablation as the standard of care. The newest ablation treatment, cryoballoon, uses a cold balloon tip. The biggest risk factor associated with the cryoballoon ablation is phrenic nerve injury (PNI)...

Using histological sections of 12 hands from 12 human fetuses at 20-34 weeks of gestation (150-290 mm) and 14 fingers (index and small) from seven donated cadavers of elderly individuals (aged 78-95 years), we compared the features of Vater-Pacinian corpuscles between these two stages of life. Corpuscles with thin, tightly packed lamellae appeared to undergo a change to thick, loosely packed lamellae at 23-32 weeks. The typical fetal corpuscle had two parts: (1) a rod-like proximal part (0.2-0.6 mm in length) extending along the proximodistal axis of the finger, and (2) a distal end (0...

Appendicitis is the most common surgical abdominal emergency in the developed world. Most of the surprises encountered during an appendectomy are usually due to the various positions of the appendix tip. Anatomical variations are an extremely rare phenomenon, with only a few case reports scattered among volumes of literature on the vermiform appendix. A new variation is described in which the appendix was intracecal and cause for surprise during surgery. A review of literature of rare anatomical variations of the appendix is also presented...

Variations in the origin of the vertebral artery (VA) is a congenital anomaly that occurs during embryological development. Multiple variations related to VA origin have been reported in the literature. Abnormal VA origin is usually determined as incidental findings during angiographic or postmortem anatomical studies. Although most of the cases are asymptomatic, in patients with VA anomaly symptoms such as dizziness have been described. The anomalous variation in the origin of the right VA is rare and separated into three categories: (1) originating from the aorta, (2) originating from the carotid arteries, (3) duplicated origin...
