上腕骨近位端骨折に対する人工骨頭置換術の術後成績 Clinical Results of Hemiarthroplasty for Displaced Proximal Humeral Fractures
[Purpose] The purpose of this is to evaluate the results of hemiarthroplasty for displaced proximal humeral fiacture. [Materials and Methods] The patients were 3 males and 7 females, with their ages ranging from 54to 82, (average of 68.7 years). The follow-up period ranged from 1 year to 8 years and 1 month (average 4 years 3 months). Seven patients had an acute 4-part fracture, two had an acute 3-part fractu re, and one had a chronic 3-part fracture-dislocation with RSD. All the cases were treated using a Neer II prosthesis.<BR>The operative results were assessed with the Japanese Orthopaedic Association (JOA) score.<BR>[Results] The average of postoperative JOA score was 72.6, range a from 46 to 92. The average active motions were forward elevation,92.2: external rotation,7: and internal rotation, L5. Relief of pain was predictable with an average of 23 points. But one patient with RSD had severe pain and limited range of motion. Three patients with a limited range of motion had difficulty in reattaching the greater and lesser tuberosities anatomically.<BR>[Conclusion] Anatomical reattachment of the greater and lesser tuberosity and early operation after injury (within 2 weeks) are important to gain satisfactory results.
