Surgical Orthopedic Anatomy
Like Duolingo, but for Surgical Orthopedic Anatomy. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.
For the part of you with thirty open tabs that never became anything.
20 levels across 3 sections, about 40 minutes end to end, roughly 8 days at five minutes a day. It moves through Internervous Planes and Deep Exposures, Dynamic Restraints and Joint Stability, and Perfusion Vulnerability and Compartment Mechanics.

Key ideas in Surgical Orthopedic Anatomy
- The cephalic vein sits within the deltopectoral groove and typically receives most tributaries laterally from the deltoid, making lateral retraction safest to prevent avulsion
- The pectoral nerves (medial and lateral) enter the pectoralis major medially while the axillary nerve courses posteriorly/laterally into the deltoid, creating a genuine internervous interval
- Superficial dissection splits the interval between extensor carpi radialis brevis (radial nerve proper) and extensor digitorum communis (PIN)
- The deep layer exposes the supinator, within whose substance the PIN runs obliquely
- The supinator must be elevated subperiosteally off the radius from medial to lateral with the forearm fully supinated to translate the PIN away from the operative field
- Brachialis possesses dual innervation, with the musculocutaneous nerve supplying roughly the medial two-thirds and the radial nerve supplying the lateral third (often proprioceptive/sensory and motor)
- Splitting the muscle intermuscularly along this neurovascular seam protects the musculocutaneous nerve medially and allows safe lateral mobilization without denervating the entire muscle body
- The superficial window exploits the boundary between the brachioradialis (radial nerve) and pronator teres / flexor carpi radialis (median nerve)
- The radial artery and sensory branch of the radial nerve run together along the medial edge of the brachioradialis and must be mobilized together
- Distally, the deep bed exposes the pronator quadratus innervated by the anterior interosseous nerve
- The lateral window lies lateral to the iliopectineal fascia and contains iliopsoas and the femoral nerve
- The middle window spans between iliopectineal fascia and the lateral border of the rectus sheath, containing external iliac vessels
- The medial window opens through the floor of the inguinal canal to access the pubic symphysis and Retzius space
- Hip extension and knee flexion maximally relax the sciatic nerve across the posterior pelvis
- Knee extension combined with hip flexion puts the sciatic nerve under maximum stretch over the posterior acetabular rim
- Leaving a cuff on the detached obturator internus and gemelli provides a protective shield when retracting the sciatic nerve medially
You've tried the other tabs
Thirty open tabs. Four facts you actually kept.
You watched. You nodded. By Sunday it was gone.
One answer, then back to scrolling.
Eight weeks. You meant to finish. You didn't.
Tomo gives Surgical Orthopedic Anatomy the Duolingo treatment: levels, streaks, and quick quizzes that test what you just learned. That game loop is what the tabs above never had, so it's the one you actually finish.
Here's what playing it feels like
A real question from this course. Take your best guess.
When opening the deltopectoral plane in the anterior shoulder, which way should you retract the cephalic vein to minimize bleeding?
