手指屈筋群で手内筋のみが残存する2例と,屈筋群あるいは伸筋群の麻痺を伴う手指損傷患者5例の,計7例14手(年齢25.0±8.1歳)の示指MP関節の屈曲トルク値を,自作の測定器具を用いて測定し,健側手と対照させて,示指のMP関節屈曲における各筋の関与を検討した.症例1と2は,屈筋腱が再断裂し,人工腱挿入術後6カ月で,手指屈筋群は手内筋のみが残存しており,症例3と4は,術後6カ月で深指,浅指屈筋の回復が認められたが,手内筋の回復が見られない手内筋マイナス群で,症例5と6は,手内筋の回復も見られた手内筋プラス群である.また症例6と7は,術後3カ月と6カ月でMP関節屈曲トルク値を測定し,術後3カ月ではともに橈骨神経麻痺によりdrop fingerを示し,術後6カ月では麻痺は回復して指の伸展運動は可能であった.また全ての症例は,他動的に手指の関節可動域に制限はなかった.手内筋のみが残存する症例1と2の屈曲トルク値は,各々41.0%,39.2%で,手内筋マイナス群の症例3と4は,11.2%,19.1%,手内筋プラス群の症例5と6は,42.5%,27.8%であった.手内筋のみが残存する症例のMP関節屈曲トルク値は健側の約40%であり,主に第一背側骨間筋によるものと考えられた.また手内筋マイナス群はともにプラス群より小さく,これは,MP関節での手内筋による屈曲作用の低下とともに,DIP,PIP関節が屈曲位となり,MP関節での深指,浅指屈筋の屈曲作用の効率を低下させたためとも考えられた.また,橈骨神経麻痺を伴う症例6と7の術後3カ月では各々19.9%,32.1%,術後6カ月では27.8%,67.4%で,各々7.9%,35.3%増加していた.これより,伸筋群の筋力低下は,MP関節あるいはPIP関節での拮抗作用の低下を生じさせ,MP関節の屈曲力の低下に影響していると考えられた.

There are 2 cases where the finger flexor muscle group and the inner hand tendons are still intact, and the flexor muscle group and the extensor muscle group are paralyzed and accompanied by finger damage. Five patients were injured, totaling 7 patients and 14 hands (age 25.0 ± 8.1 years old). The flexion index of the MP joint of the index finger was measured.を, the self-made measuring instrument is used to measure the いて, the uninjured hand is used to measure the MP joint flexion of the index finger, and the MP joint flexion of the index finger is measured. The relationship between each tendon and each tendon is the same. Case 1 and 2, the flexor tendon was re-ruptured, 6 months after artificial tendon insertion, The finger flexor tendons group and the internal tendons in the hand are still intact, case 3 and 4, 6 months after surgery, deep finger flexor tendons, superficial finger flexor tendonsの Reply to められたが, Hand Neijiu no Reply to see られないHand Neijin マイナス群で, Cases 5 and 6, Hand Neijin's recovery method Measurement of MP joint flexion and joint flexion at 1 month, 3 months after surgery It is possible to stretch the finger after 6 months of paralysis, and it is possible to stretch the finger after 6 months of surgery. The full range of motion of the joint of the finger is not possible.にlimited はなかった. Hand Neitsuji のみが remaining する case 1 and 2 flexion トルクつは, each 々41.0%, 39.2% で, hand tetra tendon マイナス group の case 3と4は, 11.2%, 19.1%, the remaining syndrome of the Handuchi Muscle group 5と6は, 42.5%, 27.8% Example: MP joint flexion is about 40% of the uninjured side, and the main part is the first dorsal side Interosseous tendon によるものと卡えられた.ラス群より小さく,これは,MP joint でのhand inner tendon flexion action のlow とともに,DIP,PIP joint flexion position となり,MP joint でThe efficiency of the flexion action of the deep finger and superficial finger flexors is low, and the radial bone paralysis is accompanied by symptoms. 19.9%, 32.1%, 6 months after surgery, 27.8%, 67.4%, each 7.9%, 35.3% increased, Stretching group The muscle strength is low, the MP joint is low, the antagonism of the PIP joint is low, and the flexion strength of the MP joint is low, the influence is low.
