スプラウトピンによる上腕骨近位端骨折の治療経験

Abstract

We performed osteosynthesis for proximal humeral fractures using Sprout pins. The cases consisted of eight females, with an average age of 79.2 years. Under general anesthesia, the fractures were reduced, and alignment of the fracture was checked using an image intensifier. Sprout pin was inserted from the deltoid tubercle to the humeral head, along a medial portion of the humeral neck under image intensifier control. This operative procedure provided less surgical stress and sufficient stability for fractures. Pendulum exercise was started two days after operation. Active assisted exercise was started three days later. These patients were assessed using the Japanese Orthopaedic Association Shoulder Scoring System (JOA score).Eight patients had sound union of fractures and satisfactory results. The average JOA score was 89.6 points at discharge from the hospital, except for one case of inferior subluxation. We confirmed that osteosynthesis for proximal humeral fractures using Sprout pin is very useful.
