text: An extensive network of ligaments surrounding the joint capsule helps the elbow joint maintain its stability and resist mechanical stresses.
text: MCL approach depends on the pathology Kocher approach (ECU/anconeus) used to address the LCL complex, common extensor tendon origin, coronoid, capitellum, and/or radial head fractures when approaching joint (ie, for radial head fractures) during deep dissection, make incision slightly anterior to midline of the radial head to protect the posterior fibers of the LCL complex take care with retractor placement to avoid injury to the PIN medial approach used to address the MCL, flexor/pronator mass origin, and/or comminuted coronoid fractures identify and protect the ulnar nerve posterior approach reconstruction coronoid fractures ORIF rarely needed, as most fractures involve only the coronoid tip (proximal to insertion of brachialis) typically approached laterally, but can also be addressed via a medial approach, especially if comminuted radial head fractures ORIF when placing fixation on the proximal radius, one must be aware of the "safe zone" (a 90° arc in the radial head that does not articulate with the proximal ulna) the "safe zone" can be identified by its relationship to Lister's tubercle and the radial styloid radial head arthroplasty indicated if radial head can not be reconstructed if radial head is replaced the replacement should be anatomic and restore normal length/size this improves the varus and external rotatory stability of the elbow, but stability isn't restored until LCL is addressed excision of the radial head leads to varus/external rotatory instability when the LCL function is absent LCL repaired or reconstructed extensor origin avulsion is common and may be repaired MCL if instability persists following LCL repair, the MCL is repaired or reconstructed hinged external fixator only necessary if elbow remains unstable after attempt at fixation as described above postoperative care depending on stability of the elbow, active ROM exercises may commence while using a brace an extension block may or may not be used
