The purpose of this study was to investigate whether the identification of Sever's disease is reliable with radiographs alone. Eighty foot radiographs (50 boys with calcaneal apophysitis and 30 healthy boys) were included in this study. Two consultant orthopaedic surgeons were instructed to make a diagnosis without clinical information on the patients. Radiologic assessments were performed in random order by each observer on two separate occasions, at least 3 weeks later. kappa-statistics were used to establish a relative level of agreement between observers for the two readings and between separate readings by the same observer. Observer A made 22 true (27.5%) diagnoses, whereas observer B made 56 true (70%) diagnoses at the first assessment. Interobserver agreement was rated as slight (kappa-value, 0.190). Observer A made 40 true (50%) diagnoses, whereas observer B made 52 true (65%) diagnoses at the second assessment. Interobserver agreement was rated as slight (kappa-value, 0.039). Intraobserver reproducibility was rated as fair for both observers (kappa-value, 0.369 for observer A and 0.253 for observer B). The results of this study showed that the radiologic identification of calcaneal apophysitis without the absence of clinical information was not reliable. Radiologic findings that were attributed to Sever's disease showed a wide variation between independent observers and between separate readings by the same observer. The diagnosis of calcaneal apophysitis is a clinical decision and radiographic assessment seems to be unnecessary.

Fracture of an osteochondroma is a rare complication. We report two cases of fractured osteochondroma in two children that were treated successfully with total excision.

Biomechanical imbalance between the hallux and the second toe and external compression of the lateral nail fold are proposed as the main reasons for ingrown toenail. Therefore, any anatomical predisposition facilitating this compression may play a role in the occurrence of ingrown toenail. The purpose of this study is to investigate the relationship between forefoot alignment and ingrown toenail. The authors retrospectively reviewed radiographs of 81 patients with ingrown toenails and compared them with 100 healthy subjects regarding forefoot alignment. Hallux valgus angle (HVA), intermetatarsal angle (IMA), and interphalangeal angle (IPA) were measured, and feet were classified according to digital formula as Egyptian, Greek, and square. The mean HVA was 14.5° ± 5.0° in the case group and 13.2° ± 5.9° in the control group. The mean IMA was 9.1° ± 2.5° in the case group and 8.6° ± 3.1° in the control group. The mean IPA was 11.9° ± 4.1° in the case group and 12.0° ± 5.1° in the control group. There was no statistically significant difference between the groups regarding HVA, IMA, or IPA (P = .123, P = .198, and P = .925, respectively). The distribution of foot types between groups was also similar (P = .967). This study has failed to demonstrate any abnormality in forefoot alignment in patients with symptomatic ingrowing toenails, and it is suggested that treatment should not be based on the correction of the anatomy if no abnormality exists.
