Abstract
Background
The medial gastrocnemius muscle flap is commonly used for the reconstruction of defects around the knee and proximal leg. The flap can be raised using either a medial or a posterior midline incision, although no studies have been done comparing the 2 different surgical approaches.
Methods
We compared the reach of the medial gastrocnemius muscle flap using either of the 2 incisions in a series of 25 fresh cadavers. All muscle flaps were elevated without division of the muscle origin. Muscle reach was calculated using the distance from a fixed bony point with the leg fully extended and the muscle under no tension. Muscle width measurements were used to calculate surface area of coverage.
Results
Muscle flaps elevated through the posterior midline incision group reached 2.02 cm farther than flaps through the medial incision (P< 0.05). This resulted in 20.3 cm 2 increase in surface area for the posterior midline incision group over the medial incision group (P< 0.05). The posterior midline incision allowed for better visualization of the vascular pedicle and dissection of fascial attachments around the pes anserinus.
Conclusions
The posterior midline incision for the elevation of the medial gastrocnemius pedicled muscle flap allows for a safe, thorough mobilization of the muscle resulting in increased muscle reach and increased surface area when compared with the medial incision. Furthermore, the posterior midline incision provides better access to the gastrocnemius muscle origin and the lateral muscle head.
