Comparative StudyPathomorphological and quantitative bacteriological findings in various forms of primary surgery on gunshot wounds of extremities.
It is well-known that 'wound excision' is essential in the primary treatment of wounds in war, particularly thorough debridement of the devitalized tissues around the path of a penetrating projectile. Nowadays, the gunshot wounds in peacetime have become prevalent. Instead of the traditional method of 'wound excision' (excision), we used the method of 'incision and drainage' (incision) in the primary surgery of these gunshot wounds of extremities. ⋯ Also, there was no difference in healing time; the wounds in both groups had healed by 19.2-21.4 days. Microscopic examination revealed a little normal muscle tissue in the necrotic zone of the incision group which might augment the repair process. These results suggest that there are no differences in the effectiveness in preventing infection between the two methods. 'Incision' might be superior to 'excision' for the management of the gunshot wounds of extremities in peacetime, as it involves a simple operation and there are advantages for tissue healing.

Case ReportsTwenty-six-years' survival with multiple bone metastasis of malignant pheochromocytoma.
The prognosis of metastatic pheochromocytoma is poor in general. There have been few instances of long-term survival reported. We report a case of a 44-year-old woman who has survived for 26 years after bone metastasis. ⋯ The primary lesion was removed, and posterior lumbar spinal fusion was performed for immobilization. The metastatic lesion in the ilium was left untouched. After 26 years, she is well despite a recurrence of the tumors in the skull and a new metastasis in the left abdomen.

Freeze-dried human bone allograft is used clinically as an adjunct to autologous bone graft. When freeze-dried human bone allograft is demineralized, the allograft is osteoinductive, since it causes bone to form heterotopically. Both types of allograft are also used alone, such as in spinal fusions, critical size defects, and periodontal therapy. ⋯ In the demineralized, freeze-dried bone from donors younger than 42 years of age, the bone induction score and new bone area were significantly higher than in the other batches of bone graft, and the area of residual particles was reduced. Both demineralized and nondemineralized bone graft from patients older than 70 years of age were encapsulated in dense, fibrous connective tissue. These results may help explain the observed differences in clinical outcome when demineralized, freeze-dried bone graft or nondemineralized, freeze-dried bone graft from different donors is used in bone regeneration applications.

Comparative StudyRupture of the patellar tendon: a review of 68 cases and a retrospective study of 29 ruptures comparing two methods of augmentation.
Rupture of the patellar tendon is a rare injury requiring acute repair to reestablish knee extensor continuity and to allow early motion. Different pathomechanisms have been postulated, and multiple techniques for repair have been described in the literature. Firstly, the current study reviews the epidemiology, pathomechanism, and risk factors. ⋯ To avoid reoperation for removal of the cerclage wire, a PDS cord can be used. The infection rate seems to be higher in the PDS group. A larger prospective study group is necessary to determine whether this phenomenon can be reproduced.

Comparative Study Clinical TrialBlood loss in anterior cruciate ligament (ACL) reconstruction with and without intercondylar notchplasty: does it affect the clinical outcome?
Blood loss is associated with any surgical procedure and should be reduced wherever possible. It was our impression that notchplasty adds to the amount of postoperative bleeding after anterior cruciate ligament (ACL) reconstruction. With posterior placement of the tibial tunnel, notchplasty is optional in many cases. ⋯ The serum hematocrit (Hct) decrease was 9.7% in group I and 7.4% in group II (p < 0.001). At 12 months after surgery, the IKDC and Lysholm score evaluations and the KT-1000 arthrometer measurements revealed no clinical differences between the notchplasty and non-notchplasty groups. Despite a 30% increase in blood loss, notchplasty has been shown to be a useful procedure to prevent graft impingement without negative side-effects.
