“…Back injury is linked in the literature to high preseason training intensity, a history of low back pain, low body weight, and stress fracture in the pars interarticularis. [26][27][28] Our multinomial regression analysis revealed significant predicting variables for back injury only: presence of scoliosis, young age, and hypermobile hip external-rotation ROM. Scoliosis is a common phenomenon among female athletes such as gymnasts, figure skaters, and dancers.…”

Context: Most studies of injured dancers have been carried out on professional adult dancers; data on young, nonprofessional injured dancers are sparse.Objective: To identify the types of injuries sustained by recreational dancers and to examine their association with age, joint range of motion, body structure, age at menarche, presence of anatomic anomalies, and physical burden (ie, practice hours en pointe).Design: Descriptive epidemiology study. Setting: The Israel Performing Arts Medicine Center, Tel Aviv.Patients or Other Participants: A total of 569 injured female dancers, aged 8 to 16 years.Main Outcome Measure(s): Dependent variables were 61 types of current injuries that were later classified into 4 major categories: knee injuries, foot and ankle tendinopathy, back injuries, and other injuries. Independent variables were age, joint range of motion, body size and shape, age at menarche, anatomic anomalies, and dance discipline (eg, hours of practice per week en pointe).Results: At least 1 previous injury had been sustained by 42.4% of the dancers. The most common injuries involved the knee (40.4%), followed by other injuries (23.4%). The relative frequency of back injuries and tendinopathy decreased with age, whereas knee injuries increased. Types of injuries were significantly associated with ankle plantar flexion, hip external rotation, hip abduction, and knee flexion. Multinomial regression analysis revealed only 3 predictive variables (with other as baseline), all for back injury: scoliosis, age, and hip external rotation.Conclusions: Joint range of motion and scoliosis may signal the potential for future injury. Young dancers (less than 10 years of age) should not be exposed to overload (especially of the back) or extensive stretching exercises.Key Words: athletes, children, practice time, scoliosis, body mass index, range of motion Key PointsIn this group of young, injured dancers, nearly half had experienced at least 1 previous injury. The most common injuries affected the knee, and knee injuries increased with age, whereas ankle and foot tendinopathy and back injuries decreased with age. Scoliosis, age, and hip external rotation were predictive of back injury.

“…We performed a thorough PubMed search for non-traumatic bilateral pedicle fractures. Thirteen previous reports were identified [2,[6][7][8][9][10][11][12][13][14][15][16][17] (Table 1). All patients presented with either low back pain, leg pain, or both.…”

“…The incidence is uncertain. In reported cases, contralateral [10], or unilateral spondylolysis [49] were associated with a pedicular cleft, and a case of a pedicular cleft with abnormal morphology due to neurofibromatosis has also been described [50]. A congenital or developmental anomaly of the affected vertebrae may be related to the formation of the pedicular clefts [41].…”

with spondylolysis and the other with degeneration of facet joints and/or intervertebral disc. Many patients with spondylolysis remain asymptomatic and certain cases become symptomatic, with low back pain and, less commonly, radicular pain. Spondylolisthesis can also be asymptomatic, but may cause low back pain, spinal instability, and radiculopathy, which requires conservative and/or surgical treatment.The incidence of lumbar spondylolysis has been reported to be 8 % in the adult population [2], and it was variable among races and sexes. Sakai et al. [3] reported that the prevalence of lumbar spondylolysis among the Japanese population between 20 and 29 years of age, found by multidetector CT, was 5.9 %, with a male to female ratio of 2:1. Spondylolysis has never been seen in newborn babies: it is seen only after walking. The upright posture and bipedal position play a role in the development of spondylolysis [4]. The prevalence of lumbar spondylolisthesis was reported to be 20.7 % in the adult population, and spondylolysis without spondylolisthesis was relatively uncommon and was only seen at the lower lumbar level [5].Although bone defects of typical isthmic spondylolysis run obliquely through the pars interarticularis, and are well depicted on oblique lumbar radiography, atypical isthmic defects have been reported in several papers [6,7]. The pathomechanism and incidence of atypical isthmic defects is not well known, and the radiographic appearance of atypical isthmic spondylolysis has not been well recognized among radiologists. Other atypical spondylolyses included various types, and two variations have been reported in the literature [8][9][10]. Unilateral spondylolysis accounts for 3-33 % of all cases of spondylolysis and has been estimated to be approximately 3-7 % of the general population [11]. It may be associated with certain athletic activities, such as cricket, ballet, and gymnastics, and the association with Abstract The purpose of this paper is to review typical and atypical imaging features of spondylolytic spondyolisthesis and natural courses. Imaging features of the typical pars defect in early phase include bone marrow edema of the isthmus on MR imaging with progression of bone defect on plain radiography or CT. There are various defect types (pedicular cleft, retroisthmic cleft) and locations (upper lumbar spine and unilateral lesions). Natural courses also vary, with different patterns of progression and stabilization. Clinical correlation of the imaging and clinical features is often difficult.
