To compare three methods of surgical treatment for infected nonunion of tibial fractures. ⋯ In terms of union and function, the best surgical treatment for infected nonunion of tibial fractures in this series was bone grafting and intramedullary rod fixation, after adequate débridement and antibiotic therapy.

To study the outcome of conservative and surgical management of spontaneous pneumothorax. ⋯ Conservative treatment, including tube thoracostomy, was effective for primary and secondary spontaneous pneumothorax. Open surgery was effective in preventing recurrence in 95% of cases in both groups.

During the initial operation on victims of multisystem trauma, life-threatening hypothermia, metabolic acidosis and coagulopathy occasionally develop. Without the immediate control of active bleeding and correction of these abnormalities, the intraoperative death rate is high. ⋯ The patient's initial surgery was abbreviated to allow the aggressive correction of hypothermia and coagulopathy before definitive reconstruction of bowel injuries. Abbreviated laparotomy for damage control should be a part of the surgical armamentarium in the management of severe abdominal trauma.

Comparative Study
Heterotopic ossification after primary cemented and noncemented total hip arthroplasty in patients with osteoarthritis and rheumatoid arthritis.
To compare the frequency and severity of heterotopic ossification (HO) in patients with osteoarthritis or rheumatoid arthritis who undergo cemented or noncemented total hip arthroplasty. ⋯ Cemented total hip arthroplasty increases the frequency of HO only in osteoarthritic hips. Compared with Brooker's grades 2 and 3 HO, grade 4 HO significantly lowers the Harris hip score after total hip arthroplasty.

Randomized Controlled Trial Comparative Study Clinical Trial
Heparinized saline versus normal saline in maintaining patency of the radial artery catheter.
To compare the ability of normal versus heparinized saline infusion to maintain patency of the radial artery catheter used for monitoring or multiple blood sampling. ⋯ There is no significant difference between flushing with normal saline and heparinized saline in the maintenance of radial arterial line patency. However, the use of a continuous heparinized flush solution in pressurized arterial lines is beneficial in that it results in greater accuracy of blood pressure monitoring than normal saline infusion.
