“…During ossi cation, this nutrient foramen is located in the growth center [24] and its presence is almost constant [10,20].

“…The proximal, ascending branch travels to the nutrient foramen at the scapular spina base and then to the spinoglenoid notch where it anastomoses with the suprascapular artery [12,27].

Introduction: The circum ex scapular artery (CSA) has been described in detail in the literature, but the groove, i.e., the circum ex sulcus (CFS), formed by the artery on the lateral pillar of the scapula has been completely neglected. The aim of the present study was to describe the variability and anatomy of the CFS.Material and method: The study was based on the examination of 103 pairs of dry bone specimens of adult scapulae, i.e., 206 specimens, including 92 (46 pairs) male and 114 (57 pairs) female specimens. In the rst step, quantitative criteria were de ned for assessment of the CFS presence and type. Subsequently, statistical analysis of the obtained data was performed.Results: The study revealed considerable variability of the arterial groove, which was well-developed in 33% (type A), shallow in 40% (type B), and absent in 27% (type C) of cases. The mean distance between CFS and the infraglenoid tubercle was 3.3 cm (range, 2.5-5.4), which corresponds to the proximal third of the lateral border of the scapula. Conclusion:The study has con rmed variability of the arterial groove (CFS) and its localization in relation to the inferior glenoid rim. The ndings are clinically important, particularly in relation to the Judet approach to scapular fractures.

“…Most nutrient foramina however were found in the supraspinous fossa (29.7%) and were least present in the peri-glenoid area (17.7%). The presence of a nutrient canal in the glenoid region in this patient cannot be ruled out [ 17 ].…”

Intraosseous schwannomas represent an extremely rare subgroup of schwannomas, accounting for <1% of all primary bone tumors. They mostly occur in the mandible, the maxilla, the sacrum, and they are also seen in long bones. We herein report a rare presentation of an intraosseous schwannoma in the glenoid of a 49-year-old patient. She complained of shoulder pain and was referred to the orthopaedic oncologist after detection of a suspicious lesion on imaging. Biopsy revealed benign spindle cells and immunohistochemistry was positive for S100. Because of the rarity of these intraosseous schwannomas it is important to recognize their radiological and histological features and make a differential diagnosis with other lytic tumors. Only if these characteristics are recognized, correct treatment can be given with definite curettage and bone grafting and correct follow-up with avoidance of unnecessary adjuvant therapy.

“…Previous studies have reported the location and number of nutrient foramina in various bones using macroscopic evaluation ( 6 – 10 ) and three-dimensional (3D) computed tomography (CT) measurement ( 11 , 12 ). Because the bone surface is irregular, there is still no uniform location for the nutrient foramina in the proximal femur.…”

BackgroundA detailed depiction of nutrient foramina is useful for defining guidelines and minimising iatrogenic damage during hip surgery. Therefore, this study aimed to define the location and frequency of nutrient foramina in the proximal femur using mapping techniques.MethodsOne hundred dry human cadaveric proximal femurs, comprising 56 left and 44 right femurs, were scanned using a three-dimensional scanner, with scanning distance 200 mm, precision 0.01 mm, and measuring point 0.04 mm. The image resolution of 1,310,000 pixels was obtained. Digital imaging models were acquired from the proximal femur surface. All the nutrient foramina in each model were identified and marked. The nutrient foramina models were superimposed on one another and oriented to fit a standard template of the femur’s proximal aspect. Three-dimensional mapping in the proximal femur’s nutrient foramina was performed.ResultsThe nutrient foramina’s location and dense zones were identified. The dense zones were distributed along the vascular course and gaps between the muscle attachment sites. Eighteen dense zones were identified and found to be location-dependent. They were located in the central part of the fovea capitis femoris, subcapital and basicervical areas of the femoral neck, and muscle attachment gaps of the femoral trochanter.ConclusionsThe terminal branch of the nutrient vessels entering the nutrient foramina is at risk for iatrogenic damage during hip surgeries, especially in cases of close bone exposures. There are 18 dense zones that need to be considered for a safer approach to the proximal femur. To minimise iatrogenic damage to the nutrient vessels entering the nutrient foramina, the dense areas should be avoided when technically possible.
