“…(c) pain was elicited on sitting [6,13,14,16,17,18], and (d) a traction force on the hamstrings played a role in both groups [7,13,14,16].…”

“…Avulsion of the apophysis of the ischial tuberosity has been described as apophysiolysis [7,14], apophyseolysis [6], epiphyseolysis [22] and fracture [1,2,5,11,13,17,18,19,23]. The diagnosis of fracture was based on the sudden onset of pain [14] and a crescent-shaped epiphysis separated from the tuberosity [19].…”

We report five cases of irregularity of the apophysis of the ischial tuberosity (Kremser's disease). In four, plain radiographs showed that the density of the radiolucent area increased within several months of a minor injury. Serial computerised tomography demonstrated new bone formation across the widened apophyseal plate, although there was no change in the shape or density of the apophysis itself. The separation repaired and remodelled spontaneously within a year. In one case, CT showed that the apophyseal ossification centre was smaller than that on the opposite side. Our findings showed that in four cases the irregularity of the apophysis of the ischial tuberosity may have been caused by an avulsion fracture, but the appearance in the fifth case was a normal variant of the ossification centre.

“…The origin of the hamstrings is partly from the secondary ossification centre on the ischial tuberosity and ischial apophysiolysis and avulsion is well recognised between puberty and the age of 25; this time span representing the appearance of the centre and its eventual fusion with the ischial body between 18 and 25 years of age (Milch, 1953;Hamada et al, 1963;Abbate, 1945).…”

“…The unusual nature of this lesion may be partly because the origin of the hamstrings from the apophysis in the adolescent conveys an increased lever action compared with that in the adult (Hamada et al, 1963), and partly because in adults hamstring tears at the musculo-tendinous junction in mid-thigh posteriorly protect the ischium from such overuse injury. 94 …”
