Abstract
Intertrochanteric femur fractures are frequently encountered in older adults and can substantially affect mobility, independence, and quality of life. Vitamin D is essential for maintaining calcium and phosphate balance, bone mineralization, skeletal integrity, and muscle function. This review evaluates the potential influence of vitamin D deficiency on fracture healing and functional recovery following surgical management of intertrochanteric femur fractures. Low vitamin D status is commonly reported among patients with hip fractures, particularly in older individuals with limited mobility, inadequate dietary intake, reduced sunlight exposure, and multiple comorbidities. Evidence suggests that vitamin D deficiency may contribute to reduced muscle strength, impaired physical performance, and difficulties during postoperative rehabilitation. However, its direct association with radiological fracture healing remains uncertain. Although vitamin D participates in bone remodeling and mineralization, existing clinical studies have not consistently established that deficiency independently results in delayed union or non-union. Similarly, supplementation may benefit musculoskeletal health, but evidence for improved fracture union and functional outcomes is variable. Therefore, vitamin D assessment and correction should be incorporated into comprehensive postoperative care together with appropriate fixation, adequate nutrition, calcium intake, early mobilization, and structured rehabilitation. Further prospective studies are needed to clarify the clinical significance of vitamin D status and determine the optimal supplementation strategy after intertrochanteric fracture surgery.
