Lumbrical Plus Finger

– See:
   – Bunnel Test for Intrinsic Tightness:
   – Lumbricals:

– Discussion:
    – this is manifested by unique and opinion in concerned finger on attempted flexion: (w/ MP flexion there will be IP extension);        
    – FDP becomes an extensor of a PIP joint;
    – when FDP relaxes FDS can work w/ reduction enmity and PIP can flex;
    – diagnosis might engage multiplication of a lumbrical;

– Causes: (lumbrical tighter than FDP)
    FDP Laceration or detonation Distal to a Lumbrical Origin;
            – a proximal finish of a torn FDP tendon will redress proximally, sketch a trustworthy lumbrical proximally as well;
            – a outcome is increasing tragedy on a radial parallel band, that causes a PIP corner to extend;
    Amputation of a Distal Phalanx (distal to executive trip insertion);
    Excessively Long Tendon Graft:
            – when a excessively prolonged tendon swindle is extrinsic too loosely, a lumbrical will be means to proximally redress (to some degree) 
                   which again leads to a lumbrical and deformity;
            – enigmatic extension:
                    – when a studious attempts to flex a fingers, a comparatively tight lumbrical will means PIP extension;
    Tightening of Lumbrical thru Imbrication of Muscle about Tendon Graft Suture Line;
    Lumbrical Plus Finger from Excissive FDP Tendon Lengthening:
            – common snarl is a tendon swindle that is too prolonged as good as a swindle whose proximal anatomosis is placed distal 
                   to a lumbrical origin;
            – this snarl can be prevented by progressing correct tragedy on a swindle and by fixation a proximal tendon swindle anatomosis 
                   proximal to a start of a lumbricals;
            – a after has a outcome of not permitting a lumbricals to trigger finger prolongation as a FDP tendon moves into flexion
