The Hip: Preservation, Replacement and Revision

Musculoskeletal Considerations in Pregancy and Post Pregnancy



- Use of Medications in Pregnancy:
    - calcium supplementation 
    - intra-articular steroids 
            - note that intra-articular steroids may interfere w/ lactation in nursing mothers;
    - ref:
            The use of antirheumatic medication during pregnancy and in the puerperium

- Surgical Considerations:
    - positioning:
            - avoid supine positioning because of hypotensive effects from aortocaval compression by the enlarged uterus (decreased cardiac output);
            - consider use of right hip wedge, lateral tilt positioning (left side down), or manual displacement of the uterus;

- DVT Prophylaxis:
    - pregnancy causes a hypercoagulable state;
    - w/ orthopaedic injuries consider need for subcutaneous fractionated heparin and SCDs;
    - warfarin is contraindicated.

- Widening of the Symphysis Pubis:
    - begins at the 10-12 week of pregnancy and becomes maximum near term;
    - ref:

- Ankylosing Spondylitis:
    - unlike rheumatoid arthritis (which temporarily improves with pregnancy),  ankylosing spondylitis may be activated or worsened by pregnancy;
          - among female patients w/ AS, up to 20% may develop initial symptoms during pregnancy;
