type II)
o Documented ipsilateral coracoacromial and/or AC ligament disruption or
it equivalent (coracoid fracture, i.e., AC joint disruption)
OPERATIVE

simultaneous involvement of 20% to 30% of the articular surface and/or
persisting subluxation of the humeral head.)

associated with

67. OPERATIVE INDICATIONS

68. Outcomes :
Advantages
- improved result with ORIF for clavicle fractures with 2 cm.
shortening and 100% displaced
- improved functional outcome and less pain with overhead
activity
- faster time to union
- decrease symptomatic mal-union rate
- improved cosmetic satisfaction
- increase shoulder strength and endurance
Disadvantages
- increase risk of need for future procedures (implant removal,
infection)
OPERATIVE

- avoids the supraclavicular cutaneous nerves commonly
injured with plating
- disadvantages

- limited contact precontroured, dynamic
compression plate

TECHNIQUES

72. Open reduction, Plate and Screw fixation
- approach
- beach chair or supine
- direct superior vs inferior incision
- biomechanics
- superior vs anteroinferior plating
- higher load to failure (S > A)
- plate strength with inferior bone comminurion
(A > S)
- lower risk of neurovascular injury (A > S)
- lower removal of deltoid attachment (S > A)

- operative 16.4 weeks
- non operative 28.4 weeks
TECHNIQUES

74. FIXATIONS
