The excavated type of rhomboid fossa of the clavicle is a relatively neglected anatomical structure that can potentially cause diagnostic problems. Its unilateral occurrence may be confused by the physician as avascular necrosis, osteomyelitis, or even a tumour. We studied 80 routine chest radiographs and identified the clavicles with excavated type of rhomboid fossa. The sex, sidedness, and handedness were recorded. An excavated type of rhomboid fossa was present in 43 clavicles (26.88%), appearing more frequently in males than in females. In addition, the incidence of the excavated type of rhomboid fossa was greater on the right side than on the left. That type of fossa was also present more frequently on the right side in right-handed specimens and on the left side in left-handed specimens. The high incidence of the excavated type of rhomboid fossa on the dominant hand supports the mechanical theory of fossa formation. Radiologists and physicians should be aware of this fossa, as it may resemble a pathological condition.

The aims of the study were to identify factors that may result in difficulties in intubation, and to compare the results obtained when an experienced and when a less experienced anaesthesiologist was involved. The 96 patients included in the study were evaluated for difficult intubation according to the following scales: Mallampati, upper lip bite test (ULBT) and Patil. The mobility of the cervical segments of the vertebral column, the distance between the jugular notch of the sternum and the chin and the anatomical constitution of the body were other factors that were taken into consideration. Statistical analysis was performed in order to identify factors that may result in difficulties in intubation for an experienced and for a less experienced anaesthesiologist.

Despite intensive anatomical research during the last century, anatomical structures or variations of these structures may still cause confusion or even iatrogenic injury. A matter of debate is the sternalis muscle. We present a review of the literature of the sternalis muscle with special emphasis on its clinical anatomy., (Copyright 2004 Via Medica)
