Knowledge of rare variants of the FDP is of high clinical importance for physicians examining patients for tendon lacerations and especially for hand surgeons operating tendon injuries.
During routine dissection at our Department of Anatomy both cases were observed.
Variations of flexor digitorum superficialis and flexor digitorum profundus muscles of the little finger were observed in two cadavers. In both cases, the flexor digitorum profundus muscle for the little finger was absent. Moreover, in the first case, the flexor digitorum superficialis muscle for the little finger was hypoplastic and in the second case it featured variable insertion.
There were found only four cases in previous literature describing absent flexor digitorum profundus tendon without any muscle attachment to the base of the distal phalanx. Furthermore, all previously described cases were observed in living patients. To our best knowledge, a case report in cadaver has yet not been reported and is of high importance for hand surgeons examining the hand for tendon injuries.
了解 FDP 的罕见变异对于检查肌腱撕裂患者的医生，尤其是手部外科医生检查肌腱损伤具有重要的临床意义。
在我们解剖学系的常规解剖过程中观察到了这两个病例。
在两个尸体中观察到小指的屈指浅肌和屈指深肌的变异。在这两种情况下，小指的屈指深肌都不存在。此外，在第一种情况下，小指的屈指浅肌发育不良，而在第二种情况下，其附着点可变。
在之前的文献中仅发现了四个描述没有屈指深肌腱且没有任何肌肉附着在远节指骨基底的病例。此外，所有之前描述的病例都是在活体患者中观察到的。据我们所知，目前还没有在尸体中报告过这种病例，这对手部外科医生检查手部肌腱损伤具有重要意义。
