Experience has demonstrated that good quality parts distal to the flexor digitorum superficialis
(FDS) insertion improve function when they are properly replanted (Fig.
Detection of differential gliding characteristics of the flexor digitorum superficialis
tendon and subsynovial connective tissue using color Doppler sonographic imaging.
Review at three months revealed only a slight decrease of power (4/5) in his flexor digitorum superficialis
There are four tendons of the flexor digitorum superficialis
muscle going to fingers 2-5, responsible for flexing the middle joint of the fingers (Figure 1A), four tendons of the flexor digitorum profundus muscle also going to fingers 2-5 responsible for flexing the distal joint of the fingers (Figure 1B), and one tendon from the flexor pollicus longus muscle going to the thumb to flex the thumb (Figure 1C).
We do not believe this influenced the results of the present study since fatigue of the forearm muscle flexor digitorum superficialis
, as inferred from EMG frequency shifts, has been shown not to change as a function of grip size (Blackwell et al.
A great variety of abnormalities have been suggested: an imbalance between flexor and extensor forces, abnormal insertions or strength of the lumbrical muscle, shortening and thickening of the collateral ligaments, anomalous flexor digitorum superficialis
or profundus, faulty development of the dorsal extensor aponeurosis, and malformations of the retinaculum cutis in the palmar fascia and natatory ligaments (13).
