"Both heads of the distal biceps femoris musculotendinous unit are composed of two tendinous components the direct and anterior arms originating from the short head and long head biceps femoris muscle bellies which are partially intertwined or coalescent 1-3. The average length of the long head and short head biceps femoris tendons from the myotendinous junction to the fibular head has been quoted approximately 9 cm and 5 cm with 20% of the population showing significantly shorter variants 4."

"Function"
"There is a close relationship between the fibular insertion of the distal biceps femoris tendon and the common peroneal nerve 4."
"There are variations in the length of the distal biceps femoris tendons of both short and long heads with shorter distances between the myotendinous units and the fibular head in up to 20% of the population, thus creating an intermuscular tunnel between the more distal and posterior extension of the short head biceps femoris muscle and the lateral gastrocnemius muscle. This tunnel is considered a potential entrapment site and a risk factor for common peroneal nerve entrapment 4,5."
