Objective: To evaluate the functional and radiological results of patients with and without medial calcar continuity in plate osteosynthesis applied for a proximal humerus fracture retrospectively. Methods: The study included 27 patients to whom plate osteosynthesis was applied because of a proximal humerus fracture between January 2, 2010, and December 30, 2013, at Okmeydanı Research and Training Hospital. Patients were separated into Group A with medial calcar continuity and Group B without medial calcar continuity. On the radiographs taken postoperatively and at the final follow-up examination, measurements were taken of the humeral head height and the humeral neck-shaft angle. The presence of avascular necrosis was recorded. Results: The functional and radiological results of the patients were evaluated after a mean follow-up of 39.1 months. No statistically significant difference was determined between Groups A and B in respect of the postoperative and the final follow-up humeral head height (P > 0.05). No statistically significant difference was determined between Groups A and B in respect of the postoperative and the final follow-up humeral neck-shaft angle (P > 0.05). Plate breakage was seen in one patient without medial calcar continuity. Penetration of the screw into the joint was determined in one patient in Group A and three patients in Group B. No avascular necrosis or infection was seen in any patient. Conclusion: When the surgical process has not damaged the soft tissue and sufficient stability has been achieved, providing calcar continuity is not an absolute condition.
