Abstract Introduction The purpose is based on anatomical basis, combined with three-dimensional measurement, to guide the clinical repositioning of proximal humeral fractures, select the appropriate pin entry point and angle, and simulate surgery. Methods 11 fresh cadaveric specimens were collected, the distance of the marked points around the shoulder joint was measured anatomically, and the vertical distance between the inferior border of the acromion and the superior border of the axillary nerve, the vertical distance between the apex of the humeral head and the superior border of the axillary nerve, the vertical distance between the inferior border of the acromion and the superior border of the anterior rotator humeral artery, and the vertical distance between the apex of the humeral head and the superior border of the anterior rotator humeral artery were marked on the 3D model based on the anatomical data to find the relative safety zone for pin placement. Results Contralateral data can be used to guide the repositioning and fixation of that side of the proximal humerus fracture, and uniform data cannot be used between male and female patients. For lateral pining, the distance of the inferior border of the acromion from the axillary nerve (5.90 ± 0.43) cm, range (5.3-6.9) cm, was selected for pining along the medial axis of the humeral head, close to the medial cervical cortex, and the pining angle was measured in the coronal plane (42.84 ± 2.45)°, range (37.02° ~ 46.31°), and in the sagittal plane (28.24 ± 2.25)°, range (19.22° ~ 28.51°). The pin was advanced laterally in front of the same level of the lateral approach point to form a cross-fixed support with the lateral pin, and the pin angle was measured in the coronal plane (36.14 ± 1.75)°, range (30.32° ~ 39.61°), and in the sagittal plane (28.64 ± 1.37)°, range (22.82° ~ 32.11°). Two pins were taken at the greater humeral tuberosity for fixation, with the proximal pin at an angle (159.26 ± 1.98) to the coronal surface of the humeral stem, range (155.79° ~ 165.08°), and the sagittal angle (161.76 ± 2.15)°, with the pin end between the superior surface of the humeral talus and the inferior surface of the humeral talus. The distal needle of the greater humeral tuberosity was parallel to the proximal approach trajectory, and the needle end was on the inferior surface of the humeral talus. Conclusion Based on the anatomical data, we can accurately identify the corresponding bony structures of the proximal humerus and mark the location of the pin on the 3D model for pin placement, which is simple and practical to meet the relevant individual parameters.

Proximal humerus fracture is common fracture 4-6% of all fractures (1), third most common non vertebral fracture in elderly >65 years (2), affecting female more than males in ratios of 2:1.Approximately half (51%) of these fractures are displaced, the majority of which involve the surgical neck (77%). (3) Surgical treatment (mainly internal fixation or humeral head replacement) is being increasingly used (4).Management of each fracture is dependent of patient factors, fracture pattern, and complexity.Case scenario:33 years old female not known to has any medical illness, presented to the emergency department with right shoulder pain and inability to move it after motor cycle accident. X-rayshowed proximal humerusfracture dislocation Upon Post-operative follow up patient developed sever inferior humeral head subluxation, With intact axillary nerve sensation and motor exam.Discussion:proximal humerus fracture is common, fracture pattern and type, with patient factors will guide your management.proximal humerus fracture dislocation is more difficult and challenging to surgeon in managing such fracture, with inferior hemeral head subluxation is common can reach to 42% in the radiographic incidence among proximal humerus fracture.
