When surgically addressing a sheared posteromedial fragment of a tibial plateau fracture, the patient is positioned prone or supine-bumping.
The classic posteromedial approach (e.g., Lobenhoffer or modified posterior approach) utilizes an internervous/intermuscular interval between which two structures to directly visualize the posterior medial cortex?

During a nerve conduction study for suspected severe carpal tunnel syndrome, the neurologist notes paradoxical preservation of intrinsic muscle function in the hand.
The patient has a Martin-Gruber anastomosis. Anatomically, this anomaly represents a neural communication in the forearm bridging from the:

In Zone II of the flexor tendon system, the Flexor Digitorum Superficialis (FDS) tendon splits to allow the Flexor Digitorum Profundus (FDP) tendon to pass superficially.
The anatomical site where the FDS tendon splits and its slips decussate before inserting on the middle phalanx is known as:

According to the Levine-Edwards classification of Traumatic Spondylolisthesis of the Axis (Hangman's Fracture), a Type II fracture demonstrates significant anterior translation and angulation of C2 on C3.

When reconstructing the Medial Patellofemoral Ligament (MPFL) for recurrent patellar instability, non-anatomic femoral tunnel placement leads to graft failure or joint stiffness. Intraoperatively, the true anatomic femoral footprint (Schottle's Point) is verified fluoroscopically on a perfect lateral view.

A 7-year-old child with severe Legg-Calve-Perthes disease presents with increasing pain and a stiff hip. An arthrogram demonstrates that during active abduction, the enlarged, extruded lateral portion of the femoral head physically impinges against the lateral lip of the acetabulum, prying the tjoint apart rather than reducing concentrically. This phenomenon is called "Hinge Abduction."
The preferred surgical management to salvage this hip is:

A 14-year-old sustains an ankle injury. Radiographs show a fracture of the distal tibia that appears as a Salter-Harris Type III fracture on the AP view and a Salter-Harris Type II fracture on the lateral view.
This "Triplane Fracture" typically occurs during the transitional phase of physeal closure. The biomechanical mechanism driving this specific fracture pattern is:
