Thanks for your query.
Your spontaneous pneumothorax
must have been secondary one i.e it must have been caused by some underlying lung disease. What I concluded is you underwent bronchopleural fistula which means air leaking from airway into the pleural cavity
, which you must have demonstrated as air leaks in the drain while coughing. Surgeon had no choice than to wait for the spontaneous closure of it or via applying mild suction.
Your hip problem may be secondary to your weakness, or else if the primary infection was tuberculosis
, it might have caused arthritis
of the hip...
