上腕骨頚部骨折に対するポララスヒューメラルネイルの治療経験

抄録

Twenty patients (14 females,6 males) with fractures of the proximal humerus were treated by internal fixation with a Polarus humeral nail. The mean age was 66.3 years old (range 21 to 93 years old). Seven patients had 2parts,8 patients had 3-parts and 5 patients had 4-part fractures. They were operated on within an average of 7days after injury. The range of follow-up period was 5 to 29 months. Clinical and radiological bone union was confirmed in 18 patients. The mean score of the clinical outcome was 83 (range 44 to 100 points) evaluated according to the Japanese Orthopaedic Association. The good functional results indicate that the Polarus humeral nail was a satisfactory mechanical device for the treatment of proximal humeral fractures because it was less invasive and was a strong fixation.
