Fracture shaft humerus (UPPER LIMB TRAUMA)

Fracture shaft humerus

1. HUMERAL SHAFT FRACTURES Dr K SRINIVASA REDDY Assistant professor

2. INTRODUCTION Humeral fractures traditionally treated nonsurgically , with predictably satisfactoryoutcomes.Strong bias formerly existed against surgica lintervention due to high rate of complications.Both operative and nonoperative treatments have been refined.

3. ANATOMY Humeral diaphysis extends from the upper borderof the insertion of the pectoralis majorproximally to the supracondylar ridge distallyFracture alignment determined by the location ofthe fracture relative to the major muscleattachments , most notably the pectoralis majorand deltoid attachments

4. Deforming forces Example of a fracture distal to pectoralis majorattachment and proximal to deltoid tuberosityAdduction of proximal fragment results

5. Example of a fracture distal to deltoidtuberosityThe proximal fragment is abducted and shorteningoccurs at fracture site due to pull of biceps andtriceps

6. Classification Systems Classification based on fracture descriptor AO Classification

7. Fracture Descriptors Location Pattern Low-energy vs. high-energy Open / Closed Injury

8. Mechanism of Inju ry Dir ect or indirect forces Violent muscle contraction

9. Physical examination Cardinal signs of long bone fracture include Pain Swelling Deformity Look for associated injuries Document neurovascular exam! Radial Nerve Function
