is attached to the linea aspera along supra condylar line up to the adductor tubercle.
The thigh muscle MRI revealed that the fatty infiltration of the adductor magnus
, semimembranosus, long and short heads of the biceps femoris, and vasti muscles, with relative sparing of the rectus femoris, was the predominant change observed in the EDMD, LGMD, and advanced-stage L-CMD phenotypes, although the involvement of the vasti muscles was not prominent in the early stage of L-CMD.
This was accompanied by high-grade partial thickness tearing of adductor magnus
and obturator internus muscles.
The thigh adductor muscles include gracilis, adductor longus, adductor brevis, adductor magnus
and pectineus muscle.
The sciatic nerve rests on the ischium and then passes posterior to the obturator internus, quadratus femoris, and adductor magnus
The needle was subsequently advanced more deeply (0.5-1 cm) and after the identification of the adductor magnus
muscle contraction (hip adduction), an additional 5 mL of 1% lidocaine was injected (for posterior branch block).
With increasing of dropping height, the peak forces increased for most muscles in the lower limb, in which the rectus femoris (RF), GMax, gluteus medius (GMed), vastii, biceps femoris (BF), and adductor magnus
all showed significant changes.
Botulinum toxin A was injected into the bilaterally adductor magnus
(dose 100 U) and adductor longus (dose 50 U) muscles, with a total dose of 300 U at the sixth month after the OP intoxication.

An MRI of left lower extremity was obtained that showed intense edema with fluid tracking along the adductor magnus
and quadratus femoris muscle and multiple small rim-enhancing fluid collections within the left adductor magnus
, which correlated with the site of pain (Figure 1).
We hereby present a case of metastasis to the adductor magnus
muscle of a 78-year-old male previously diagnosed with GIST of the rectum.
The posterior obturator nerve branch travels in the fascia between the adductor brevis and adductor magnus
muscles (Figure 1(a)).
