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. J Bone Joint Surg Am 2004;86:940-947. 
                   - A comparison of open reduction and internal fixation and primary total elbow arthroplasty in the treatment of intra-articular distal humerus fractures
                               in women older than age 65. J Orthop Trauma 2003;17:473-480. 
                   - A multicenter, prospective, randomized, controlled trial of ORIF versus TEA for displaced intra-articular distal humeral frx in elderly patients.


- Operative Technique:


- 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.

(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:
    - 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 the distal-medial edge of the condyle will encroach on the cubital tunnel and may irritate the ulnar nerve;
              - in these patients, anterior transposition may indicated;
