Abstract

Introduction: The frequency of proximal humeral fractures shows an increasing tendency, especially in the elderly, who are frequently affected by osteoporosis. The adequate treatment of complex, displaced fractures poses a serious challenge. Among surgical treatment options, osteosynthesis with an angular stable plate is preferred, however, the implant-related complication rate may be exceptionally high. In our present study, we report the short-term outcomes of our new method of valgising angular stable plate fixation which we use for multifragmentary, displaced proximal humeral fractures in elderly patients.

Materials and methods: We retrospectively evaluated the clinical and radiological outcomes of 52 patients (46 female and 6 male, age: 71.9 ± 9.6) who suffered dislocated three- or four-part fractures and underwent valgising angular stable plate fixation.

Results: Mean follow-up time was 17.3 months, while the functional outcomes were as following: excellent in 26, good in 18, moderate in 5 and poor in 3 patients. The mean Constant-Murley Score was 82.5 ± 11.2. Functional outcomes only showed significant correlation (p = 0.031) with age and were proven unrelated to fracture type, BMI and known primary diseases. The cumulative complication rate was 9.6% and revision rate was 5.8%. Neurological deficit, pseudoarthrosis or avascular humeral head necrosis did not occur during the follow-up period.

Conclusions: Valgising angular stable plate fixation that we apply for proximal humeral fractures provided favourable functional outcomes and a low postoperative complication rate due to the optimal head and plate placement. The method is especially effective for the treatment of displaced three- and four-part fractures with weakened, osteoporotic bone structure.
