Sternal Foramen

Sternal foramina are a well-known variant anatomy of the sternum and carry the risk of life-threatening complications like pneumothorax or even pericardial/cardial punction during sternal biopsy or acupuncture. There have been numerous studies numerous studies examinimg prevalence of sternal foramina, but the study of the exact anatomical relationship to intrathoracic structures has received little attention. In a retrospective study of 15 patients with sternal foramina, the topographical anatomy in respect to vital chest organs was examined. In most patients, the directly adjacent structure was the lung (53.3%) or mediastinal fat (33.3%). Only in three patients, the heart was located directly adjacent to a sternal foramen (20%). Theoretically, if the needle is inserted deep enough it will at some point perforate the pericardium in all examined patients. There was no correlation between the patient habitus (i.e., thickness of the subcutaneous fat) and the distance to a vital organ. In this sample, pericardial punction would have not occured if the needle is not inserted deeper than 2.5 cm. Given the preliminary nature of the data, general conclusions of a safe threshold for needle depth should be made with caution. To minimize the risk of hazardous complications, especially with sternal biopsy, preprocedural screening or image guidance is advocated.

Abstract BACKGROUND Additional landmarks for identifying the suprascapular nerve at its entrance into the suprascapular foramen from an anterior approach would be useful to the surgeon. OBJECTIVE To identify landmarks for the identification of this hidden site within an anterior approach. METHODS In 8 adult cadavers (16 sides), lines were used to connect the superior angle of the scapula, the acromion, and the coracoid process tip thus creating an anatomic triangle. The suprascapular nerve's entrance into the suprascapular foramen was documented regarding its position within this anatomical triangle. Depths from the skin surface and specifically from the medial-most point of the clavicular attachment of the trapezius to the suprascapular nerve's entrance into the suprascapular foramen were measured using calipers and a ruler. The clavicle was then fractured and retracted superiorly to verify the position of the nerve's entrance into the suprascapular foramen. RESULTS From the trapezius, the nerve's entrance into the foramen was 3 to 4.2 cm deep (mean, 3.5 cm). The mean distance from the tip of the corocoid process to the suprascapular foramen was 3.8 cm. The angle best used to approach the suprascapular foramen from the surface was 15° to 20°. CONCLUSION Based on our study, an anterior suprascapular approach to the suprascapular nerve as it enters the suprascapular foramen can identify the most medial fibers of the trapezius attachment onto the clavicle and insert a finger at an angle of 15° to 20° laterally and advanced to an average depth of 3.5 cm.

Satisfactory Outcome

Coracoid fractures are uncommon, mostly occur at the base or neck of the coracoid process (CP), and typically present with ipsilateral acromioclavicular joint (ACJ) dislocation. However, CP avulsion fractures at the coracoclavicular ligament (CCL) attachment with ACJ dislocation have not been previously reported. A 59-year-old woman receiving glucocorticoid treatment fell from bed and complained of pain in her shoulder. Radiographs revealed an ACJ dislocation with a distal clavicle fracture. Three-dimensional computed tomography (3D-CT) reconstruction showed a small bone fragment at the medial apex of the CP. She was treated conservatively and achieved a satisfactory outcome. CP avulsion fractures at the CCL attachment can occur in osteoporotic patients with ACJ dislocations. Three-dimensional computed tomography is useful for identifying this fracture type. CP avulsion fractures should be suspected in patients with ACJ dislocations and risk factors for osteoporosis or osteopenia.

The literature reports that 70% of the cases of sinus tarsi syndrome are post-traumatic, following an inversion sprain, and that 30% result from inflammatory disorders, such as rheumatoid arthritis, ankylosing spondylitis, and gouty arthritis. However, in the case presented, talipes equinovarus deformity and sinus tarsi syndrome coexisted. One of the corrective goals in the management of the talipes equinovarus deformity is the realignment of the articulation between the medial plantarly deviated talar head and the anteromedial segment of the calcaneus. The calcaneus must be rotated from a plantarflexed position into a dorsiflexed position. The posterior tubercle will be moved down and in, with the anterior process moved up and out away from the talar head. By correcting the plantarflexed varus attitude of the calcaneus, it is put in a valgus position that often closes down the sinus tarsi upon weightbearing. This compression may result in pain over the lateral aspect of the midfoot with hindfoot instability, as seen in the case presented. As a result of the abnormal anatomical relationship of the talus and calcaneus, the patient developed severe pain in the sinus tarsi. Based on the medical history and present postoperative results, the authors find a long-term sequela of talipes equinovarus deformity to be sinus tarsi syndrome.

✓ A case of mucocele of the posterior ethmoid sinus presenting as unilateral blindness without pain, proptosis, or diplopia is reported. Computerized tomography (CT) demonstrated the precise anatomical relationship of the mucocele to the optic nerve inside the optic canal. It is proposed to use the term “optic canal syndrome” for patients with such clinical and CT presentation. Combined transcranial excision and transnasal drainage resulted in dramatic recovery of vision.
