Background: Now a day's many surgeries are done around the head and neck of femur like femoral head resurfacing arthroplasty for managing advanced hip-joint degeneration. Thus, it is vital for an orthopaedic surgeon to exactly understand the vascular supply of the neck of femur. The knowledge of distribution of foramina and their relation to the retinacula of Weitbrecht will help orthopaedic surgeons to choose their management technique for various injuries. So, this study was undertaken to study the number, size and distribution of nutrient foramina in all the surfaces of neck of femur and their relations to the retinacula of Weitbrecht.
Materials And Method: Study was conducted on 200 adult dry femora. The retinacula of Weitbrecht are first defined later the subcapital, transcervical and basicervical regions of the femoral neck are marked. The number of foramina, size and their distribution in relations to the retinacula of Weitbrecht were observed. Later the results were analyzed statistically.
Results: 40.01% of foramina were observed in the subcapital region, 31.74% in basicervical and 28.24% were noted in transcervical region. The nutrient foraminal density was significantly higher in the upper retinacula (57.03%), followed by anterior retinacula (27.3%) and least in the region of inferior retinacula (15.66%). It was observed that most foramina were less than 1 mm diameter followed by 1-2 mm diameter foramina.
Conclusion: This knowledge of foraminal distribution in femoral neck will be helpful in surgeries involving the hip joint and femoral head & neck fractures.

Although Josias Weitbrecht described the retinacula of the hip joint in his 1742 Syndesmologia, the anatomist Cesare Amantini of Perugia specifically studied the medial retinacula he referred to as the pectineofoveal fold in a late 19th-century monograph. This particular synovial fold stretches from the lesser trochanter to the osteocartilaginous junction of the femoral head along a virtual line connecting the lesser trochanter and the fovea for the ligament of the head. Although mentioned by some anatomists and radiologists, and despite its possible involvement in specific hip joint pathologies (fractures, impingements), it is surprising that Amantini's pectineofoveal fold remains ignored by most anatomy and clinical anatomy books.

Objective: To investigate associations between femoral head necrosis (FHN) and injury to the retinaculum of Weitbrecht in patients with femoral neck fractures who had undergone initial trials of either closed reduction or direct open reduction.
Methods: This prospective observational study included 110 patients with displaced femoral neck fractures admitted to the Sixth People's Hospital Affiliated to Shanghai Jiaotong University and Shanghai Tongji Hospital between January 2008 and May 2017. Among these, 25 patients underwent initial closed reductions, and 85 patients underwent an open reduction directly.

"Syndesmologia siue historia ligamentorum corporis humani", published in 1742 by a German anatomist Josias Weitbrecht (1702-1747), who for a long time lived and worked in St. Petersburg, is the first comprehensive textbook of syndesmology. The accuracy and quality of the accompanying illustrations are fascinating, even after almost 300 years.

Background: The retinacular arteries provide major supply to the femoral head, their injuries may lead to the femoral head necrosis (FHN) in femoral neck fractures. Although the femoral neck fracture was seriously displaced in some patients, FHN did not occur, which suggests that the blood supply is not fully blocked. This study was aimed to find the association between the structure of the retinacula of Weitbrecht and the mechanism of protecting retinacular arteries from being injured.
