The purpose of this study was to determine the in vivo function of the biceps as an active depressor of the humeral head. Thirty-eight shoulders were examined: 19 shoulders with rotator cuff tears (RCT, avg age 59 yrs) and 19 shoulders with normal MRI findings of the rotator cuff (Control, avg age 55yrs). A special arm brace which was fixed to the upper arm was used to keep the biceps in active contraction (biceps loading) during arm elevation. The subjects were asked to grasp a rubber band attached to the distal end of the brace, pull it proximally, and keep the elbow flexed against the resistant force producted by the band. The x-ray were obtained with the arm elevated at 0,45,90 degrees in the scapular plane with and without pulling the band. The center of the humeral head was determined using NTH image and compared between the groups with and without biceps loading. Without biceps loading, the positions of the humeral head at 0,45 degrees were significantly higher in RCT than those in Control (p=0.0101, p=0.0020, respectively). After loading the biceps, the humeral head was depressed significantly at each degree in RCT (P=0.0082, p=0.0259, p=0.0059, respectively). As a result of biceps loading, there were no more significant differences in the positions of the humeral head between RCT and Control (p=0.3285). The positions of the humeral head in RCT with biceps loading were similar to the positions in Control without biceps loading. This is the first study to show the in vivo function of the biceps as an active depressor. From these results, we conclude that the biceps is an active depressor of the humeral head in cuff-defficient shoulders.

日本にもようやく反転型人工肩関節が2014年に導入され,これまでの肩疾患に対する人工肩関節の役割が大きく変わることになった.従来の解剖学的人工肩関節は,腱板が正常な変形性肩関節症に適応があるため,全国調査でも肩関節手術全体の1%未満にすぎなかった.反転型人工肩関節は腱板断裂性関節症によい適応があり,この人工関節の導入を待ち望んでいた医師,患者は数多い.2015年には全人工肩関節のうち解剖学的人工肩関節は25%であり,反転型人工肩関節が導入2年目ですでに75%を占めるようになった.解剖学的人工肩関節および反転型人工肩関節の特徴と術後のリハビリテーションについて要点を解説した.

Each muscle of the rotator cuff is known to have several intramuscular tendons which provide attachment to numerous muscle fiders. The anatomical relationship between intramuscular and extramuscular tendons needs to be determined to know the distribution of the force to the rotator cuff tendon. The purpose of this study was to clarify the morphology of the transitional zone of intramuscular to extramuscular tendons of the rotator cuff.The muscle fibers of cuff muscles of 20 embalmed shoulders without full-thickness rotator cuff tears were removed to examine the transitional zone of the intramuscular to extramuscular tendons macroscopically. Histological sections of the musculotendinous junction were perpared to evaluate the transitional forms microscopically.We defined the intramuscular tendon as the tendon inside the muscle belly and the extramuscular tendon as the tendon outside the muscle. The extramuscular tendons from the rotator cuff tendon distally. Location was expressed as the % position of the anterior and posterior margins of the musculotendinous junction. The intramuscular tendons of the infraspinatus, teres minor, and subscapularis were contiguous to the whole extramuscular tendons and that the supraspinatus was located in the anterior one-third of the extramuscular tendon(0±0% to 28±15%). Microscopically, the intramuscular tendon of the supraspinatus formed a tendon fiber bundle and was continuous with the second of five layers of the extramuscular tendon (Clark and Harryman,1992).Conclusion: The connection of intramuscular tendon to extramuscular tendon was specific to each cuff muscle. The intramuscular tendon of the supraspinatus was attached to the anterior one-third of the extramuscular tendon and was contiguous to the second layer.

クリニカルパスを使用することで処置,介助,リハビリテーション(以下,リハビリ)のケア実施日が早くなったか,さらに入院日数がどれくらい短縮したかを明らかにする目的で,クリニカルパスを使用していない人工股関節全置換術(total hi parthroplasty ; THA)患者15例(以下,コントロール群)とクリニカルパスを使用した8例(以下,パス群)とを比較検討した.処置項目では,パス群の抗生剤投与期間が平均7日有意に短縮した.介助項目では,ヘッドアップ30度開始日が平均1日,ヘッドアップ自由開始日が平均3日,端座位開始日が平均2日有意に短縮した.リハビリ項目では,リハビリ室訓練が平均9日,全荷重立位が平均15日,松葉杖歩行が平均11日有意に開始日が早まった.平均入院日数は,術前14日,術後11日,全体で26日,パス群で有意に短縮していた.パス群8例の術後経過はすべて良好で,入院日数の短縮が術後成績に影響することはなかった.セメントTHAを行う患者にクリニカルパスを適用すれば,介助,リハビリの開始時期が早くなり,結果として入院日数短縮につながった
