Fractures in Brief: Olecranon Fractures [PDF]

Clinical Orthopaedics & Related Research, 2012
Olecranon fractures are relatively common injuries, accounting for approximately 10% of upper extremity fractures in adults [26]. These fractures may result from a direct blow to the proximal ulna, or indirectly, via the forceful contraction of the triceps against resistance (typically, during a fall onto an outstretched hand).

Hangman’s fracture vs hanged-man’s fracture vs hangee’s fracture [PDF]

Acta Neurochirurgica, 2013
not necessarily a male. The conventional name of “hangman’s fracture”, therefore, should be “hanged-person’s fracture”. Accordingly, we suggest that a more suitable terminology for the so-called “hangman’s fracture” may be the “hangee’s fracture”.

Stress concentration of perforated cement sheath and the effect of cement sheath elastic parameters on its integrity failure during shale gas fracturing

Frontiers in Materials, 2022
Due to the extremely low porosity and permeability of shale, fracturing is often used to develop shale gas reservoirs. During shale fracturing, extremely high fracturing pressure may invalidate the integrity of the cement sheath and bring hidden dangers ...
