The "general practice class"--an eligible compulsory course in undergraduate medical education: didactical structure, teaching targets and implementation.

Undergraduate medical education in the field of general practice currently faces two considerable challenges: enhancing the attractiveness of general practice for all students and contributing to the necessary future rural physician workforce in primary care. Thus, we introduce a curriculum-based concept called the "General Practice Class" (Klasse Allgemeinmedizin) as an elective compulsory course to be taken during preclinical study. The aim of this concept is to strengthen the program focus on primary care in rural areas for interested students at an early stage.Since October 2011, the "General Practice Class" in Halle-Wittenberg offers learning experiences in regard to GP professional culture and a practice-oriented learning environment for 10% (n=20) of the freshman students. Each participating student is assigned to an individual GP mentor, who acts as a "professional example" and accompanies the student during the entire course of study. The concept of the "General Practice Class" is considered to be an innovative project due to the close connection between practical experience, problem-oriented skills training, early patient contact, and the accompanying face-to-face mentorship, starting from the beginning of preclinical study.

The posterior branch of the axillary nerve: an anatomic study.

BACKGROUND: Surgery on the posterior aspect of the shoulder has become accepted practice for a number of pathological conditions affecting the scapula and the glenohumeral joint. Despite this trend, the anatomy of the posterior branch of the axillary nerve has not been well characterized. The purpose of the present study was to determine the innervation pattern and surgical relationships of the posterior branch of the axillary nerve. METHODS: Nineteen fresh-frozen human cadaveric forequarter amputation specimens were dissected through a posterior approach. The location of the posterior branch of the axillary nerve and its anatomical relationships with surrounding structures were documented and measured with use of digital calipers. RESULTS: The posterior branch separated from the main anterior circumflex branch of the axillary nerve immediately anterior to the origin of the long head of the triceps muscle at the six o'clock position on the glenoid. It coursed posteriorly, adjacent to the inferior aspect of the glenoid rim for an average distance of 10 mm (range, 2 to 17 mm) before dividing into the superior-lateral brachial cutaneous nerve and the nerve to the teres minor. The nerve to the teres minor coursed medially along the posterior aspect of the inferior part of the glenoid rim for an average distance of 18 mm (range, 11 to 25 mm) before entering the muscle at its inferior border. The superior-lateral brachial cutaneous nerve coursed inferiorly, deep to the posterior aspect of the deltoid. It became superficial by passing around the medial border of the muscle at an average of 8.7 cm (range, 6.3 to 10.9 cm) inferior to the posterolateral corner of the acromion. CONCLUSIONS: The posterior branch of the axillary nerve has an intimate association with the inferior aspects of the glenoid and shoulder joint capsule, which may place it at particular risk during capsular plication or thermal shrinkage procedures. The superior-lateral brachial cutaneous nerve and the nerve to the teres minor always arise from the posterior branch. Thus, loss of sensation over the deltoid may indicate loss of teres minor function. The posterior aspect of the deltoid has a more consistent supply from the anterior branch of the axillary nerve, necessitating caution when performing a posterior deltoid-splitting approach to the shoulder.
