Question
Frozen pelvis is seen in ‑
| A. | Osteoarthritis |
| B. |
Pott’s disease |
| C. |
Actinomycosis |
| D. |
Reiter’s disease |
|
Correct Answer » C Explanation |
 |
A “frozen pelvis” refers to extensive fibrosis and adhesions in the pelvis, leading to fixation of organs such as uterus, ovaries, bowel, and bladder. It makes surgical dissection extremely difficult.
Actinomycosis is a chronic granulomatous infection caused by Actinomyces israelii, characterized by:
- Dense fibrosis
- Extensive adhesions
- Abscess and sinus formation
Pelvic actinomycosis (often associated with long-term IUCD use) can produce a classic frozen pelvis, sometimes mimicking malignancy.
Explanation of Other Options:
A. Osteoarthritis
Degenerative joint disease; does not cause pelvic adhesions
B. Pott’s disease
Tuberculosis of the spine; may cause cold abscess but not frozen pelvis
D. Reiter’s disease
Reactive arthritis; affects joints, not pelvic adhesions
