RESUMO
Isolated fractures of the capitellum are rare injuries and account for 1% of all elbow injuries. The purpose of this study is to evaluate the clinical outcomes of 11 Type I capitellum fractures treated by open reduction and internal fixation using at least two standard Herbert screws between 1998 and 2003. The average age of the patients was 27.5 years. The mean follow-up time was 23.4 months. The final postoperative assessment was made at the 12th month. The results were evaluated according to the Mayo Elbow Performance Index. We obtained excellent result in eight patients and good result in three patients. We recommend open reduction and fixation with Herbert screws inserted from the posterior surface of the lateral epicondyle and early mobilization in Type I fractures of the capitellum.

The necrotizing effects of the heat, particularly at more than 50 degrees C, produced by the exothermic polymerization process associated with the acrylic implant cement polymethylmethacrylate (PMMA) are well documented. The temperature changes that occur are dependent on the thickness of the PMMA. The current study investigates the hypothesis that the heat produced by the bone cement may be reduced by the choice of stem design and by pre-cooling the hip prosthesis. The thermal alterations at the bone-cement interface were measured in an in vitro model. The results indicated that a temperature decrease of approximately 7 degrees C could be achieved by pre-cooling the prosthesis, and by changing the shape of the prosthesis stem from flat and wide to round.

Penetrating injuries to abdomen and especially deep gluteal injuries causes vascular and non vascular injuries which necessitates emergency surgery. Surgical management of the penetrating injuries is very difficult, especially exploration of the gluteal region is very difficult. Management of the injury of iliac artery branches is extremely difficult. Two cases with penetrating injury to the gluteal region in 1998 and 2000 one was operated on urgently and the other was operated on electively. Coil embolization was tried to be performed for elective case but intervention was unsuccessful. In both cases internal iliac artery was ligated and aneurysm was repaired. There were no complications in postoperative period. In postoperative angiographic controls, aneurysm in the internal iliac artery was regressed and there were no vascular complications at this region such as hematoma. Penetrating injuries at gluteal region causes injury to the internal iliac artery branches which seriously necessitates emergency management, internal iliac artery ligation and repair.

A series of eight cases is presented in which similar fractures of the shaft of the humerus occurred during the throwing of hand grenades. Transient paresis of the radial nerve accompanied the fracture in one patient. In seven patients, the fracture healed without complication. In the remaining case, non-union developed, and surgical treatment was instituted. The mechanism of the fracture is discussed with reference to the literature.
