PURPOSE: The extensor indicis proprius (EIP) is a muscle of the forearm that originates from the posterior surface of the ulna and the adjacent interosseous membrane and attaches to the index finger. Many anatomical variations of this muscle have been reported in the literature. The extensor digitorum brevis manus (EDBM) is a variant muscle found on the back of the wrist and hand. These muscle variants should be considered in the context of clinical syndromes and reconstructive hand surgery...

PURPOSE: Nerve-sparing radical prostatectomy (NSRP) is based on anatomical considerations that are still controversial. The aim of this study is to define and describe the anatomy of the fascias surrounding the prostate in a histoembryologic model and during open and laparoscopic approaches to assess their importance in surgical practice. METHODS: An anatomical dissection of three fresh cadavers was conducted to reproduce an open approach. Complementary data under laparoscopic conditions were obtained from images captured from the video feed during a laparoscopic NSRP performed via a transperitoneal approach...

PURPOSE: The pulmonary venoatrial junction (PVAJ) has recently received attention due to the widespread use of catheter ablation for atrial fibrillation. However, the literature lacks a consensus in the definition of the PVAJ. We aim to review the inconsistent definitions for the PVAJ and related implications in imaging and catheter ablation for atrial fibrillation. RESULTS: The PVAJ as described by embryology, gross anatomy, histology and imaging is ambiguous, leading to disparities in its definition...

OBJECTIVES: To review current theories about etiology of varicocele and pathogenic mechanisms leading to a progressive disorder of spermatogenesis in relation to the subfertility or infertility these patients may present with. To evaluate its current anatomical knowledge of the normal venous drain of the testicle and its variations that may condition relapse or failure of the treatment of varicocele. To systematically review pathologic testicular lesions in patients with varicocele. To establish factors that may have prognostic significance on post-treatment fertility...

AIM: To review the impact of Tomorrow's Doctors on anatomical teaching in the UK and Ireland. To establish in particular whether a consensus has emerged on: (a) the duration and format of teaching, and (b) the impact on staffing and on the four main anatomical disciplines of gross anatomy, histology, embryology and neuroanatomy. METHOD AND RESULTS: A postal survey of 28 anatomy departments was carried out. This yielded a response rate of 75%. Twelve departments used systems-based curricula, five used problem-based curricula, and four used a traditional regional format...
