> 20 degrees posterior tilt is also a significant risk factor for reoperations (Palm et. al, 2009, Acta Orth.)
Tip-Apex Distance (TAD)
Placement of the collum screw tip in femoral head should be < 25 mm from the apex for minimum risk of failure
Femoral shaft fractures are associated with
< 10 % have fem. neck fractures, commonly missed (50 %)

Should be treated with screws/plate + retrograde nailling if dislocated, if no dislocation then recon antegrade nailing is OK
Femoral nailing in supine position increases risk for
internal rotation

compare with contralateral limb

Pressure over volar pole of scaphoideum when at the same time moving from ulnar deviation to radial deviation. Positive if pain + dorsal subluxation of scaphoideum

Common in assoc. with dist. radius fractures

Test in:
* maximum pronation - dorsal part
* neutral and radial deviation - ulnocarpal ligaments
* meximum supination - volar part
