Complications of K-wire fixation of fractures and dislocations in the hand and wrist.
Kirschner wire (K-wire) fixation of fractures and dislocations of the hand and wrist is a common procedure. Of the 590 K-wire fixations performed on 236 patients, 36 (15.2%) experienced complications which included osteomyelitis, tendon rupture, nerve lesion, pin tract infection, pin loosening or migration. ⋯ K-wire fixation is a simple but demanding procedure that cannot be left to an inexperienced resident. Elimination of technical failure, supervision in the operating room, close monitoring, prompt treatment upon discovery of a complication, and improvement of patient compliance can reduce the rate of complications.

ReviewUltrasonography as a diagnostic modality in Osgood-Schlatter disease. A clinical study and review of the literature.
Sonographic examination of the knee has been proposed by several authors in the past as a simple and reliable method to diagnose Osgood-Schlatter disease (OSD). Ultrasound was used to compare the knees of 25 boys and 10 girls with typical OSD with 35 symptom-free knees of an aged-matched group of children. Based on recorded data, patients were categorized (one affected knee in each individual) according to the classification system proposed by De Flaviis et al. in 1989. ⋯ This distribution of cases was found to be statistically similar to the initial findings reported by De Flaviis and colleagues. This study therefore supports the validity and reproducibility of their classification method for the ultrasonographic evaluation of children with OSD. This is only the first step, and further assessment of this classification is still required to elucidate its clinical as well as its prognostic value.

To investigate the demographic details and patterns of injuries related to horse handling, we reviewed 637 horse-related injuries in 581 stable- or stud-workers in a representative area of thoroughbred stabling in Japan. We found that (1) injuries occurred most frequently in a group of a relatively young workers, with a seasonal variation; (2) the principal mechanism of injury was kicks, which accounted for 39.2% of all injuries, including 11 serious and one lethal visceral injuries; (3) the upper half of the body was more frequently involved than the lower half; and (4) the peripheral bones (hand and foot) and the ribs accounted for more than half of 148 fractures. These findings are distinct from those in horse-riding injuries reported in the literature and emphasize the importance in developing preventive strategies specifically for workers in horse stables.

Sizable glomus tumors with cystic changes in the ankle are extremely uncommon. This paper describes painless glomus tumors with cystic changes arising in the ankle of a 22-year-old woman. At the age of 14, a painless mass was noticed on the lateral side of the left ankle, and at age 21, another mass appeared on the medial side of the same ankle. ⋯ Microscopically, the tumor consisted of perivascularly arranged cells with punched-out, round, and regular nuclei. Immunohistochemically, the tumor cells expressed SMA and HHF-35, indicating smooth muscle cell characters. The patient had no recurrence at 2 years after surgery.

Avascular necrosis of femoral head after gamma-nailing for unstable intertrochanteric fractures.
We reported on 7 cases of avascular necrosis of the femoral head after treatment of an unstable intertrochanteric fracture with the Asian Pacific gamma-nail. The incidence was about 1.16% (7 of 604) in our series. ⋯ Avascular necrosis was found about 6 months to 3 years after the initial operation, and all the fractures were solidly united at the final diagnosis. The possible etiologies were initial high energy trauma and combining basal neck fracture and iatrogenic damage of the blood supply to the femoral head.
