Imaging tests will help confirm the diagnosis of spondylolysis or spondylolisthesis. In some cases, tight hamstrings may cause a patient to stand awkwardly or walk with a stiff-legged gait. The doctor will also observe your child's posture and gait (the way they walk). Your child's doctor will carefully examine your child's back and spine, looking for: Children who participate in sports that place excessive stress on the lower back are more likely to have a diagnosis of spondylolysis or spondylolisthesis.
They will want to know if your child participates in sports. Your child's doctor will begin by taking a medical history and asking about your child's general health and symptoms. Patients with high-grade slips are more likely to experience significant pain and nerve injury and to need surgery to relieve their symptoms and prevent further deterioration. A high-grade slip occurs when more than 50% of the width of the fractured vertebra slips forward on the vertebra below it. In children and adolescents, this slippage most often occurs during periods of rapid growth - such as an adolescent growth spurt.ĭoctors commonly describe spondylolisthesis as either low grade or high grade, depending upon the amount of slippage. In spondylolisthesis, the fractured pars interarticularis separates, allowing the injured vertebra to shift or slip forward on the vertebra directly below it. Often, patients with spondylolysis will also have some degree of spondylolisthesis. Spondylolysis can occur in people of all ages without injury or sports participation. For this reason, it is the area most vulnerable to injury from the repetitive stress and overuse that characterize many sports.
The pars interarticularis is the weakest portion of the vertebra. Fracture can occur on one side or both sides of the bone. Most commonly, this fracture occurs in the fifth vertebra of the lumbar spine, although it sometimes occurs in the fourth lumbar vertebra. The pars interarticularis is a small, thin portion of the vertebra that connects the upper and lower facet joints.
#Stress fracture in lower back crack#
Sacral stress fractures, though uncommon, should be included prominently in the differential diagnosis for runners with low back pain, especially if the athlete has a history of prior stress fracture or the female athlete triad.īone distance running sacrum stress fracture stress reaction stress response.In spondylolysis, a crack or stress fracture develops through the pars interarticularis (pars fracture). In severe, chronic, or recurrent cases, referral for nutritional counseling, hormonal replacement therapies, and mental health support may be necessary. Appropriate treatment includes rest from the causative activity, nutritional support, and biomechanical optimization. All 3 female patients had components of the female athlete triad-menstrual irregularity, disordered eating, and decreased bone mineral density.Ī high index of suspicion is required to make the correct diagnosis and initiate treatment for this rare condition given its association with low body mass index, vitamin D insufficiency, disordered eating, and malabsorption disorders. Magnetic resonance imaging was the key modality in all diagnoses. Two (1 male, 1 female) have yet to return to regular activity. Three of 5 patients (1 male, 2 females) returned to regular activity after diagnosis and treatment. The 5 cases were identified by performing a medical records search within the practices of the senior authors over a 3-year period from January 2016 to December 2018. Given the rarity of this condition, there is a general lack of awareness of this injury, which may lead to a missed or delayed diagnosis.
They have been described in a few case reports, with the injury occurring most often in female distance runners. Stress fractures of the sacrum are an uncommon cause of low back and buttock pain in athletes.
