Locking Compression Plate(LCP) Distal Humerus Plateを用いた上腕骨遠位端骨折の治療経験

Treatment of Distal Humerus Fractures with an Locking Compression Plate Distal Humerus Plate

　目的：Locking compression plate(LCP) distal humerus plateを用いて治療した上腕骨遠位端骨折の治療成績を明らかにする．対象と方法：男性1例，女性4例，平均72.6歳であった．術後外固定期間，術直後の整復位の保持および合併症の有無，JOAスコア，術後関節可動域について検討した．結果：骨癒合は全例で得られ，矯正損失を認めなかった．術後関節可動域は伸展－20°，屈曲120°であった．結語：術後早期から可動域訓練が可能で，JOAスコアと術後関節可動域は他のプレート固定法と差がなかった．

　Purpose：To clarify the clinical results of treating distal humerus fractures with locking compression plate (LCP) distal humerus plate.　Subjects and methods：The subjects were one male and four females, and their mean age was 72.6 years old.　According to the AO/ASIF classification system, there was one type A2 case, one type A3 case, one type C2 case and two type C3 cases.　We assessed these cases in relation to the external fixation period after the operation, correction loss, presence of complications, JOA scores, and final range of motion.　Results：The mean postoperative external fixation period in the cases with an intra-articular fracture was 1.3 days.　No external fixation was used in the cases with an extra-articular fracture.　Bone healing without correction loss was achieved in every case.　Temporary ulnar nerve paralysis occurred in two of the intra-articular fracture cases.　Average extension of the elbow was －20 degrees, and average flexion of the elbow was 120 degrees.　Conclusion：The LCP distal humerus plate provides satisfactory functional results when used to treat distal humeral fractures.
