Practice questions
- A routine cadaveric dissection of the gluteal region and posterior thigh reveals a communicating branch between the posterior femoral cutaneous nerve and another nerve. Which nerve was involved in the reported case?
- During an attempted posterior femoral cutaneous nerve block, stimulation elicits an inferior-gluteal-nerve motor response. In light of the reported anatomical variant, which interpretation is most appropriate?
- What is the principal evidence limitation when using the reported PFCN–inferior gluteal nerve communication to predict its prevalence in patients?
- In a cadaveric study of superficial upper-thigh lymphatics, which collector group drained to two large nodes inferolateral to the saphenous bulb?
- A surgeon is planning a groin lymphatic flap. According to the cadaveric study of superficial lymphatics, what medial limit was recommended to help preserve lymphatic function?
- A patient is followed after vascularized lymph node transfer using a groin donor site. Which additional region should be included in circumference measurements according to the cadaveric lymphatic study?
- In the cadaveric study, where did the local superficial collectors of the upper thigh drain?
- The superolateral superficial inguinal nodes receiving local upper-thigh collectors were also reported to drain which regions?
- An ICG-lymphography study investigated gluteal collecting-vessel directions in limbs without a dermal backflow pattern. Which description best matches its sampling method?
- In the ICG study, posteromedial-pattern lymphatic pathways from the most lateral injection point H5 were observed in how many of the 20 limbs?
- Which statement accurately describes the ICG study's finding for posterolateral-pattern pathways from the medial injection point H1?
- Which conclusion is best supported by the study using multiple ICG injections across the gluteal region?
- For the described distal thoracolumbar fascia hydrodissection approach, where was the injection target plane located?
- In the cadaveric assessment of distal TLF hydrodissection, cephalad dye spread reached approximately which level?
- Which pattern of muscle staining was observed after distal TLF–gluteal junction injection in the cadaveric assessment?
- Which structure was reported to show partial proximal staining on all six injected sides in the cadaveric assessment?
- No gross dye was seen in the sciatic nerve or sacral plexus in the six-side cadaveric assessment. Which conclusion is scientifically most appropriate?
- The distal TLF hydrodissection report used six injected sides from three fresh-frozen cadavers. What is the most appropriate interpretation of this denominator?
