Adult Humeral Inter-condylar Fractures

 - Fractures Subtypes:
    - capitellar and coronal shear frx
    - distal humeral frx 
    - lateral condyle frx 
    - medial condyle frx 
    - Muller's Classfication:
           - type A: extra-articular fracture; 
           - type B: uni-condylar fracture;
           - type C: bi-condylar fracture; 
    - controversies:
           - total elbow replacement 
                   - Distal humeral fractures treated with noncustom total elbow replacement
                   - A comparison of open reduction and internal fixation and primary total elbow arthroplasty in the treatment of intraarticular distal humerus fractures in women older than age 65..  
                   - A PRCT of ORIF vs total elbow arthroplasty for displaced intra-articular distal humeral fractures in elderly patients.
                   - Hemiarthroplasty for irreparable distal humeral fractures: medium-term follow-up of 42 patients.

  - Operative Technique: (Synthes Distal Humerus Products)
    - preparation & positioning
    - surgical exposure:
          - posterior approach;
                  - midline incision is used, skirting radial side of olecranon;
                  - always modify incision to incorporate any previous incision;
          - olecranon osteotomy:
                  - is generally reserved for intra-articular fractures;
          - alternative approaches:
                  - posterolateral (kocher) approach
                  - lateral approach:
                  - medial approach
          - generally the ulnar nerve and/or radial nerve need to be exposed prior to hardware insertion;
                  - this being the case, ask the anesthesiologist to hold paralytics at the beginning of the case and avoid
                          using the tourniquet so that a nerve stimulator can be used;
                  - once these nerves have been identified, the patient should be paralyzed inorder to facilitate the reduction;
    - restoration of fracture anatomy 
    - plate application 
          - Peri-implant failure in dual plating of the distal humerus-A biomechanical analysis with regard to screw and plate positioning.
    - assessment:
          - take the elbow thru a range of motion;
          - loss of motion may indicate that screws have crossed olecranon fossa;
          - ensure that the fixation is relatively stable, otherwise additional fixation is required;
          - have anesthesiologist reverse all paralytics so that the nerve stimulator can confirm adequate function of ulnar and/or radial nerves;
     - ulnar nerve in condylar fractures:
              - note that a plate or lag screw placed over distal-medial edge of condyle will encroach on the cubital tunnel and may irritate ulnar nerve
              - in these patients, anterior transposition may indicated; 
              - references:
                     - Fate of the ulnar nerve after operative fixation of distal humerus fractures.
                     - Is ulnar nerve transposition beneficial during open reduction internal fixation of distal humerus fractures?
                     - Predictors of Diagnosis of Ulnar Neuropathy After Surgically Treated Distal Humerus Fractures

- Complications:
    - elbow flexion contracture 
    - non union
           - Salvage of non-union of supracondylar fracture of the humerus by total elbow arthroplasty.
           - Non-union of fractures of the distal end of the humerus.
    - nerve injury:
            - Radial Nerve Injury During Double Plating of a Displaced Intercondylar Fracture
