During bowling, a twenty year old man could not pull out his middle finger from the ball in release and injured his finger. X-ray revealed a palmar fracture- dislocation of the PIP joint. We manipulated the PIP joint, but a gap remained at the fracture site on the X-ray after reduction. ⋯ Key pointsWe presented a palmar fracture-dislocation of the PIP joint in a middle finger that occured while bowling. We discussed the mechanism and suggested the main cause of the injury was the poor fit between the middle finger and the hole of the bowling ball. We advised that while bowling is recognized as a safe sport, due to its popularity we should be aware of unexpected hand injuries which may occur, especially in players at a recreational level.

The purpose of this study was to evaluate the effect of oral administration of sodium bicarbonate (300 mg·kg(-1) b.w.) on swim performance in competitive, (training experience of 6.6 ± 0.6 years) youth, (15.1 ± 0.6 years) male swimmers. The subjects completed a test trial, in a double blind fashion, on separate days, consisting of 4 x 50m front crawl swims with a 1(st) minute passive rest interval twice, on two occasions: after ingestion of bicarbonate or placebo, 72 hours apart, at the same time of the day. Blood samples were drawn from the finger tip three times during each trial; upon arrival to the laboratory, 60 min after ingestion of placebo or the sodium bicarbonate solution and after the 4 x 50m test, during the 1st min of recovery. ⋯ Key pointsSodium bicarbonate is an effective ergogenic aid, also in youth athletes. Sodium bicarbonate intake improves swimming sprint performance. Sodium bicarbonate intake increases resting blood pH and bicarbonate level.
