Abstract
The Proximal Humeral Internal Locking System (PHILOS) is being used increasingly in the treatment of proximal humeral fractures. Improvements in operative technique since its first use may represent improved functional results.
We analysed 28 cases performed in the two years following October 2006. There were 22 females and 6 males. Mean age was 65 years (Range 37–79 years). There were five 2-part, nineteen 3-part, and four 4-part fractures. Functional results were measured using the Oxford Shoulder Score, American Shoulder and Elbow Surgeons’ Score (ASES) and Constant Score (Age and sex matched). These results were compared to the patient’s non-operated shoulder to determine loss in function.
Following PHILOS fixation, the Oxford Score increased by a mean of 11 points, the ASES decreased by a mean of 25 points, and the Constant Score decreased by a mean of 31. This change was significant for all three scores (p-values < 0.01). Sub-analysis comparing patients aged < 60 years with those > 60 years and 2-part fractures with 3- and 4-part fractures showed no significant difference.
We conclude that our results confirm previously published functional data and show the patient’s age, and fracture configuration, have no impact on the results of this implant.
