Case ReportsTreatment of fractures of the humeral capitulum using fibrin sealant.
Three patients with fresh displaced fractures of the capitulum humeri were treated by the fibrin sealant method, without additional internal fixation. At follow-up, between 1 1/2 and 4 1/2 years after surgery, clinical results were very good. Fibrin sealant has many advantages over traditional osteosynthesis techniques and is therefore recommended as an effective method for treating such serious but uncommon fractures of the elbow joint.

Nonsteroid anti-inflammatory drugs prevent the recurrence of heterotopic ossification after excision.
The prophylactic effect of nonsteroid anti-inflammatory drugs on the recurrence of high-grade periarticular heterotopic ossification after resection was studied in ten patients operated on for loosening of one or both components of a cemented total hip prosthesis. These drugs, given at a standard dosage for 1-3 weeks after surgery, prevented the recurrence of heterotopic ossification. ⋯ At follow-up 2-5 years after surgery, all patients walked well and there were no clinical or radiographs signs of loosening of the prosthetic components. It is concluded that treatment with NSAIDs following resection of periarticular heterotopic ossification prevents recurrence.

Temporary impairment of blood supply has been suggested to cause bone remodeling. The degradation of cells and matrix and the attraction of resorbing cells were examined in this study. ⋯ Both supernatant from the aged bone specimens and ground bone particles exhibited significant chemotactic activity that was specifically attracting monocytes. It is suggested that soluble bone matrix proteins or degeneration products liberated during ischemic damage to cortical bone initiate the resorptive process.

Case ReportsWhich X-ray views are required in juvenile ankle trauma?
Although ankle sprains are probably the most common injury in adolescent sports people, epiphyseal injuries are missed on the presumption of a ligamentous tear. The risk of damaged ligaments has been overemphasized while the potentially dangerous epiphyseolysis has been understressed. An oblique X-ray of the ankle joint is indicated prior to "stress" pictures.

Comparative StudyBone formation in porous implants of delrin and commercially pure titanium.
Clinicians have been using implants made by titanium or delrin with varying results. In this study dividable implants, bone growth chambers (BGC), of titanium and delrin were inserted into the rabbit tibia. ⋯ Results showed that bone ingrowth into titanium implants was significantly larger than into delrin implants (P less than 0.005). The possible reasons for this are discussed.
