Introduction
The purpose of this prospective study was to assess the Constant score and radiographic outcome in 66 patients (mean age 58.7 years/mean follow-up 51 months) with a minimally displaced and/or impacted fracture of the proximal humerus treated with early mobilization.
Method
Special attention was paid to analyze the specific intrinsic parameters (age, gender, ASA grade and length of physiotherapy), injury-related parameters (classification, osteoporosis) and therapy-related parameters (initial fracture displacement, residual bony-deformity after healing, secondary fracture displacement during healing period, non-union, humeral head necrosis and omarthrosis) that may influence the final score.
Patients
There were 31 A (47%), 22 B (33%) and 13 C-fractures (19%). The median Constant score for the fractured shoulder was 89 points.
Results
All fractures healed without non-union. The radiological assessment showed in 80% a fracture-displacement with <15° angulation and/or <5-mm displacement of the greater tuberosity. At time of follow-up, the residual bony-deformity was perfect and good in 88% of cases. There was a significant association between the final Constant score and the age, ASA classification, AO (ABC) classification and initial fracture displacement.
Conclusion
Early physiotherapy, with a short period of immobilization is a sufficient therapy for management of minimally displaced and/or impacted fractures of the proximal humerus.
