Introduction: The optimal positioning of the proximal humeral locking plate in the surgical treatment of proximal humeral fractures remains a topic of ongoing investigation and refinement.

Objectives: The main objective of the study is to find the proximal humeral locking plate positioning to the pectoralis major tendon in achieving the proper calcar screw location.

Material and methods: This prospective observational study was conducted at Mehar General Hospital, Haripur, KPK Pakistan from June 2022 to June 2023. Data were collected from 20 patients undergoing surgery. A total of 20 patients diagnosed with proximal humeral fractures underwent surgical treatment using a locking plate fixation technique. All surgeries were performed by experienced orthopedic surgeons specializing in shoulder and upper extremity trauma. The proximal humeral locking plate was positioned under direct visualization with reference to the pectoralis major tendon.

Results: Data were collected from 20 patients according to criteria. Mean age of the patients were 45.09± 6.2 years. There were 65% male and 35% female patients. 60% patients are with displaced fractures and 40% with non-displaced fractures. 90% of the patients shows Accuracy of Calcar Screw Placement. The Chi-square test revealed a statistically significant association (p < 0.05) between calcar screw location and the analyzed variable. Pearson correlation analysis indicated a significant correlation between plate positioning, screw location, and clinical outcomes, suggesting a potential relationship between these factors in influencing treatment effectiveness.

 Conclusion: It is concluded that aligning the proximal humeral locking plate with the pectoralis major tendon facilitates accurate calcar screw placement, enhancing biomechanical stability and surgical outcomes in proximal humeral fracture fixation.
