The medial femur condyle (MFC) cortico-periosteal flap is a popular flap for bone reconstruction. The use of a chimeric version of this flap with a skin island has been described, but anatomical arterial variation can occur that prevent its harvest. Furthermore, the donor area of the skin paddle has been debated as poor because of the scarring in a visible area and because of the difficulty in obtaining pliable thin skin. We present a fabricated chimeric MFC cortico-periosteal flap joined with a superficial inferior epigastric perforator (SCIP) flap to reconstruct and augment a sclerotic and insufficient small clavicula with the skin paddle acting as a monitor and as a substitute for the overlying skin. A 52-year-old female patient had a history of multiple refractures of the right hypoplastic clavicle with a diameter of 7 mm, resulting in a sclerotic bone with a fibrotic scar. The reconstruction was done in one surgical session using a cortico-periosteal flap from the left medial condyle and a thin SCIP flap from the left groin. The area of the clavicle to be reconstructed was 3 cm, and the direct overlying skin (approximately 6 × 3 cm) was severely scarred and painful. The MFC flap was 5 × 4 cm, while the SCIP flap was 7 × 3.5 cm. The SCIP flap artery was anastomosed on the table end-to-side to the descending genicular (DG) artery of the MFC, and the vein was anastomosed end-to-end to a comitans vein of the DG artery. The flap fully survived after an initial congestion. At 12 months, we observed a satisfactory reconstruction of the clavicle with an enhanced diameter of 12 mm. The patient recovered full function of the shoulder with no pain. Using a fabricated chimeric flap composed of a medial femoral condyle and a superficial circumflex artery perforator flap may be an additional option for tailored reconstruction of complex osteo-cutaneous defect of clavicle.
股骨内髁骨膜(MFC)皮质-骨瓣是一种常用于骨重建的皮瓣。已经描述了使用带有皮岛的这种皮瓣的嵌合版本,但可能会发生解剖动脉变异,从而阻止其采集。此外,由于皮瓣供区的疤痕在可见区域,并且由于难以获得柔韧的薄皮,因此皮瓣供区一直存在争议。我们提出了一种由 MFC 皮质-骨瓣和腹壁浅动脉穿支(SCIP)皮瓣组成的组合式嵌合皮瓣,用于重建和增大硬化和不足的小锁骨,皮瓣作为监测器并替代上方皮肤。一名 52 岁的女性患者有右侧发育不良锁骨多次骨折的病史,直径为 7 毫米,导致骨硬化和纤维疤痕。该重建在一次手术中完成,使用左侧内髁皮质-骨瓣和左侧腹股沟的薄 SCIP 皮瓣。要重建的锁骨区域为 3 厘米,直接覆盖的皮肤(约 6×3 厘米)严重疤痕和疼痛。MFC 皮瓣为 5×4 厘米,SCIP 皮瓣为 7×3.5 厘米。SCIP 皮瓣动脉在台上端对端吻合到 MFC 的降支(DG)动脉,静脉端端吻合到 DG 动脉的伴行静脉。皮瓣在初始充血后完全存活。在 12 个月时,我们观察到锁骨重建满意,直径增加了 12 毫米。患者肩部功能完全恢复,无疼痛。使用由股骨内髁和旋髂浅动脉穿支皮瓣组成的组合式嵌合皮瓣可能是重建锁骨复杂骨皮缺损的另一种选择。
