▪glenoid fractures (Ideberg) ▪scapular neck fractures –look for associated AC joint separation or clavicle fracture –known as "floating shoulder" ▪scapular body fractures –described based on anatomic location ●scapulothoracic dissociation Scapula Fracture ●Imaging ▪Radiographs –recommended views ▪true AP, scapular Y and axillary lateral view ▪CT –intra-articular fracture –significant displacement –three-dimensional reconstruction useful Scapula Fracture ●Treatment –Nonoperative ▪sling for 2 weeks, followed by early motion ▪indications –indicated for vast majority of scapula fractures –90% are minimally displaced and acceptably aligned ▪outcomes –union at 6 weeks –can expect no functional deficits –Operative ▪open reduction internal fixation Scapula Fracture Scapula Fracture AC Joint Dislocations ●Primarily in male ●25% of the dislocations of the shoulder girdle ●Number 1 injury in bicycle accidents ●Mechanism: fall or direct blow to the point of shoulder with arm adducted AC Joint Dislocations AC Joint Dislocations ●Treatment –Grade I, II ▪Immobilization in a sling –Grade III ▪Controversy with regard to op vs conservative tx –Grade IV, V, VI ▪Early surgery in young individuals Shoulder Dislocations ●Epidemiology –Anterior: Most common –Posterior: Uncommon, 10%, Think Electrocutions & Seizures –Inferior (Luxatio Erecta): Rare, hyperabduction injury Shoulder Dislocations ●Clinical Evaluation –Examine axillary nerve (deltoid function, not sensation over lateral shoulder) –Examine M/C nerve (biceps function and anterolateral forearm sensation) ●Radiographic Evaluation –True AP shoulder –Axillary Lateral –Scapular Y –Stryker Notch View (Bony Bankart) Shoulder Dislocations ●Anterior Dislocation Recurrence Rate –Age 20: 80-92% –Age 30: 60% –> Age 40: 10-15%

artery injury (older pts with atherosclerosis) –Nerve: Axillary nerve neuropraxia ●Anterior Dislocation –Traumatic –Atraumatic (Congenital Laxity) –Acquired (Repeated Microtrauma) Shoulder Dislocations ●Posterior Dislocation –Adduction/Flexion/IR at time of injury –Electrocution and Seizures cause overpull of subscapularis and latissimus dorsi –Look for “lightbulb sign” and “vacant glenoid” sign –Reduce with traction and gentle anterior translation (Avoid ER arm → Fx) Shoulder Dislocations ●Inferior Dislocations ● Luxatio Erecta –Hyperabduction injury –Arm presents in a flexed “asking a question” posture –High rate of nerve and vascular injury –Reduce with in-line traction and gentle adduction Shoulder Dislocations Shoulder Dislocation ●Treatment –Nonoperative treatment ▪Closed reduction should be performed after adequate clinical evaluation and appropriate sedation –Reduction Techniques ▪Traction/countertraction- Generally used with a sheet wrapped around the patient and one wrapped around the reducer. ▪Hippocratic technique- Effective for one person. One foot placed across the axillary folds and onto the chest wall then using gentle internal and external rotation with axial traction ▪Stimson technique- Patient placed prone with the affected extremity allowed to hang free. Gentle traction may be used ▪Milch Technique- Arm is abducted and externally rotated with thumb pressure applied to the humeral head ▪Scapular manipulation, Kocher technique,... ▪https://www.shoulderdoc.co.uk/article/1267 Shoulder Dislocations ●Postreduction –Post reduction films are a must to confirm the position of the humeral head –Pain control –Immobilization for 2-3 weeks then begin progressive ROM ●Operative Indications –Irreducible shoulder (soft tissue interposition) –Displaced greater tuberosity fractures –Glenoid rim fractures bigger than 5 mm –Elective repair for younger patients Proximal Humerus Fractures Proximal Humerus Fractures ●Epidemiology –Most common fracture of the humerus –Higher incidence in the elderly, thought to be related to osteoporosis –Females 2:1 greater incidence than males ●Mechanism of Injury –Most commonly a fall onto an outstretched arm from standing height –Younger patient typically present after high energy trauma such as MVA Proximal Humerus Fractures ●Clinical Evaluation –Patients typically present with arm held close to chest by contralateral hand. Pain and crepitus detected on palpation –Careful NV exam is essential, particularly with regards to the axillary nerve. Test sensation over the deltoid. Deltoid atony does not necessarily confirm an axillary nerve injury Proximal Humerus Fractures ●Neer Classification –Four parts ▪Greater and lesser tuberosities, ▪Humeral shaft ▪Humeral head –A part is displaced if >1 cm displacement or >45 degrees of angulation is seen Proximal Humerus Fractures ●Treatment –Minimally displaced fractures- Sling immobilization, early motion –Two-part fractures▪Anatomic neck fractures likely require ORIF. High incidence of osteonecrosis ▪Surgical neck fractures that are minimally displaced can be treated conservatively. Displacement usually requires ORIF –Three-part fractures ▪Due to disruption of opposing muscle forces, these are unstable so closed treatment is difficult. Displacement requires ORIF. –Four-part fractures ▪In general for displacement or unstable injuries ORIF in the young and hemiarthroplasty in the elderly and those with severe comminution. High rate of AVN (13-34%) Proximal Humerus Fractures Humeral Shaft Fractures Humeral Shaft Fractures ●Mechanism of Injury –Direct trauma is the most common especially MVA –Indirect trauma such as fall on an outstretched hand –Fracture pattern depends on stress applied ▪Compressive- proximal or distal humerus ▪Bending- transverse fracture of the shaft ▪Torsional- spiral fracture of the shaft ▪Torsion and bending- oblique fracture usually associated with a butterfly fragment Humeral Shaft Fractures ●Clinical evaluation –Thorough history and physical –Patients typically present with pain, swelling, and deformity of the upper arm –Careful NV exam important as the radial nerve is in close proximity to the humerus and can be injured Humeral Shaft Fractures ●Radiographic evaluation –AP and lateral views of the humerus –Radiographs after traction reposition attempt may be indicated for hard to classify secondary to severe displacement or a lot of comminution Humeral Shaft Fractures ●Conservative Treatment –Goal of treatment is to establish union with acceptable alignment –>90% of humeral shaft fractures heal with nonsurgical management ▪ 20 degrees of anterior angulation, 30 degrees of varus angulation and up to 3 cm of shortening are acceptable ▪ Most treatment begins with application of a coaptation splint or a hanging arm cast followed by placement of a fracture brace Humeral Shaft Fractures ●Treatment –Operative Treatment ▪Indications for operative treatment include inadequate reduction, nonunion, associated injuries, open fractures, segmental fract., associated vascular or nerve injuries ▪Most commonly treated with plates and screws or IM nails Humeral Shaft Fractures ●Holstein-Lewis Fractures –Distal 1/3 fractures –May entrap or lacerate radial nerve as the fracture passes through the intermuscular septum Elbow Fracture/Dislocations Elbow Dislocations ●Epidemiology –Accounts for 11-28% of injuries to the elbow –Posterior dislocations most common –Highest incidence in the young 10-20 years and usually sports injuries ●Mechanism of injury –Most commonly due to fall on outstretched hand or elbow resulting in force to unlock the olecranon from the trochlea –Posterior dislocation following hyperextension, valgus stress, arm abduction and forearm supination –Anterior dislocation ensuing from direct force to the posterior forearm with elbow flexed Elbow Dislocations ●Clinical Evaluation –Patients typically present guarding the injured extremity –Usually has gross deformity and swelling –Careful NV exam in important and should be done prior to radiographs or manipulation –Repeat after reduction ●Radiographic Evaluation –AP and lateral elbow films should be obtained both pre and post reduction –Careful examination for associated fractures Elbow Fracture/Dislocations ●Treatment –Posterior Dislocation ▪Closed reduction under sedation ▪Reduction should be performed with the elbow flexed while providing distal traction ▪Post reduction management includes a posterior splint with the elbow at 90 degrees ▪Open reduciton for severe soft tissue injuries or bony entrapment –Anterior Dislocation ▪Closed reduction under sedation ▪Distal traction to the flexed forearm followed by dorsally direct pressure on the volar forearm with anterior pressure on the humerus Elbow Dislocations ●Associated injuries –Radial head fx (5-11%) –Treatment ▪Type I- Conservative ▪Type II/III- Attempt ORIF vs. radial head replacement ▪No role for solely excision of radial head.
