We report a case of medial femoral trochlea flap used for scaphoid proximal pole reconstruction, in which the transverse branch of the descending genicular artery was vestigial. The medial metaphyseal periosteal artery was clearly the dominant pedicle supplying the trochlear region. The flap was safely raised on the medial metaphyseal periosteal artery pedicle. The incidence of this uncommon presentation remains unknown and this anatomical variant is newly described.
我们报告了一例使用股骨内上髁瓣进行舟状骨近极重建的病例，其中膝降动脉的横支退化。内侧干骺端骨膜动脉是明显的优势蒂，供应滑车区域。该皮瓣安全地在内侧干骺端骨膜动脉蒂上提起。这种不常见表现的发生率尚不清楚，这种解剖变异是新描述的。
