Free composite medial femoral trochlea osteochondral cutaneous flap for wrist scaphoid and lunate cartilage lesions: Advantages of a skin paddle.

The medial femoral trochlea flap is a chondrocorticoperiosteal flap. It has recently been described in the context of cartilage lesions. It is mainly used for reconstruction in non-union of the scaphoid's proximal pole and Kienböck disease. The medial femoral trochlea flap may be harvested with a skin island flap to monitor its vascularization. The surgical technique has been extensively described for its primary osteochondral form. However, the corticoperiosteal form has not been thoroughly studied and described. Here, we describe and report the early results of three cases of the composite medial femoral trochlea flap, with a skin paddle for postoperative monitoring, being used to reconstruct the injured proximal scaphoid and lunate.
