A back brace can be helpful to provide support and partial immobilisation. This would usually be for a period of 6 weeks, to allow the bone to heal. In most cases, complete rest is the treatment of choice. Exercises to strengthen spine and surrounding muscles.Use a seat support to improve posture whilst sitting. ![]() Maintain fitness in the pool with a buoyancy aid.Exercise with a swiss ball to increase lower back muscular stability.Wear a back brace to provide immobilisation & support.If spondylolysis is suspected, a GP may decide to refer the patient for a scan to confirm the diagnosis. This is particularly felt if standing on one leg. Typically, it is sore when the patient bends backwards and closes down the joints between the vertebra. Spondylolysis is characterised by an ache in the lower back which is exacerbated by sporting activities and eased by rest. This condition is most common in adolescents and is quite rare beyond this age group. This results in a pars fracture, causing the slipping of the vertebral body on the one below, known as spondylolysis.Īn MRI scan of the fifth lumbar vertebra, seen from the top, shows bilateral (left and right sided) fractures of the Pars. However, if the damage is excessive and the remodeling cannot keep pace with the damage, then microscopic failures (fractures) occur. In order for remodeling to occur, the body must be given adequate rest to recover from the repeated loading that occurs during sport. In healthy bone, if damage is not excessive, a biological process called remodeling occurs and new bone is deposited to heal the damage. This fatigue eventually causes microscopic cracks or micro fractures to occur across the pars. This repeated loading is of less force than it would take to produce a traumatic fracture, but because it is repeated over a period of time it eventually causes bone damage. Bone fatigue occurs in the pars as a loss of bone strength and stiffness due to repeated loading. These forces are transmitted via the bones of the spine. The lumbar spine is required to bear large loads, due to the interaction of body weight with forces generated by sporting movements that involve large muscle forces. ![]() ![]() It is not clear why, but the pars area appears to be a weak spot in the vertebra and repetitive stress to the area can lead to micro trauma and eventual fracture of the pars, resulting in a slipping forward of the vertebral body over the one below. The area that is affected by spondylolysis is a part of the bony ring known as the ‘pars’. Three bony ‘process’ stick out from this ring and provide a place for muscles to attach. ![]() The lumbar vertebra consists of a round block of bone at the front, known as the vertebral body, and a bony ring at the back. This is because this vertebra is subject to most stress during sports. The most common site for spondylolysis is the bottom-most lumbar vertebra, called L5, where the mobile lumbar spine meets the fixed pelvis. Cricket fast bowlers, possibly due to the high force twisting motion, appear to be particularly susceptible to spondylolysis, with a reported prevalence of 55% in some teams.Īt the base of the back there are five lumbar vertebrae. It is especially common in growing adolescents and symptoms are often related to the ‘growth spurt’. This condition is classified as either a bone stress reaction or a stress fracture of the lower back.
