TL;DR: Clinical symptoms, such as pain with daily ambulation and physical examination findings, including localized tibial tenderness and pain with direct or indirect percussion, that correlated with more severe tibia stress injuries were identified.
Abstract: Medial tibial pain in runners has traditionally been diagnosed as either a shin splint syndrome or as a stress fracture. Our work using magnetic resonance imaging suggests that a progression of injury can be identified, starting with periosteal edema, then progressive marrow involvement, and ultimately frank cortical stress fracture. Fourteen runners, with a total of 18 symptomatic legs, were evaluated and, within 10 days, referred for radiographs, a technetium bone scan, and a magnetic resonance imaging scan. In 14 of the 18 symptomatic legs, magnetic resonance imaging findings correlated with an established technetium bone scan grading system and more precisely defined the anatomic location and extent of injury. We identified clinical symptoms, such as pain with daily ambulation and physical examination findings, including localized tibial tenderness and pain with direct or indirect percussion, that correlated with more severe tibial stress injuries. When clinically warranted, we recommend magnetic resonance imaging over bone scan for grading of tibial stress lesions in runners. Magnetic resonance imaging is more accurate in correlating the degree of bone involvement with clinical symptoms, allowing for more accurate recommendations for rehabilitation and return to impact activity. Additional advantages of magnetic resonance imaging include lack of exposure to ionizing radiation and significantly less imaging time than three-phase bone scintigraphy.
TL;DR: Identifying a pronated foot type prior to training may help reduce the incidence of medial tibial stress syndrome by early intervention to control abnormal pronation.
Abstract: PurposeTo identify the incidence of medial tibial stress syndrome (MTSS) in a group of naval recruits undergoing a 10-week basic training period and to determine potential risk factors.MethodOne hundred and twenty-four recruits (84 men and 40 women) were followed prospectively during basic training. Anthropometric and lower limb biomechanical data were recorded at the start of the program along with injury history and previous sporting activity for the 3 months prior to enlisting. Recruits were monitored during training for development of medial tibial strees syndrome and were asked to complete an exit interview at the end of the program.ResultsForty recruits (22 men and 18 women) developed medial tibial stress syndrome, giving an incidence of 35%. A significant relationship existed between gender and medial tibial stress syndrome (P= .012), with female recruits more likely to develop medial tibial stress syndrome than male recruits (53% vs 28%). A risk estimate revealed a relative risk of 2.03. The biome...
TL;DR: In this paper, the incidence of medial tibial stress syndrome (MTSS) in a group of high school cross-country runners and to determine if a relationship exists between lower extremity structural measures and incidence of MTSS was found.
Abstract: Study Design Predictive correlational study. Objectives To identify the incidence of medial tibial stress syndrome (MTSS) in a group of high school cross-country runners and to determine if a relationship exists between lower extremity structural measures and the incidence of MTSS. Background Medial tibial stress syndrome is an overuse injury that occurs in long-distance runners. Literature exists that implicates structural deformity as a contributor to MTSS, but no studies have developed a predictive model. Methods and Measures We measured 125 high school cross-country runners for tibiofibular varum, resting calcaneal position during stance, and gastrocnemius length. Runners developing MTSS over an 8-week period were placed in the injured group (2 men, 13 women; age 15.3 years ± 1.0), and 21 randomly selected uninjured runners were placed in the uninjured group (13 men, 8 women; age 15.7 years ± 1.5). Navicular drop was measured for runners in both groups. Reliability of measures was determined using an ...
TL;DR: Compared with healthy athletes, the results suggest struc tural and functional differences in the feet and ankles between healthy athletes and those with shin splints.
Abstract: Thirteen adult male athletes (long-distance runners and orienteerers without foot problems) and 35 male athletes with shin splints were compared with respect to: 1) the position of the lower leg and the heel while standing, 2) the passive range of mobility in the subtalar joint, and 3) the angular displacement between the calcaneus and the midline of the lower leg (Achilles tendon angle) while running with bare feet on a treadmill. In standing, the two groups differed statistically significantly in the Achilles tendon angle, which values were greater in the shin splint group. With respect to passive mobility, the athletes with shin splints had significantly greater (P less than 0.05-0.01) angular displacement values in inversion, eversion, and in their sum than the control group. While running, the Achilles tendon angle of the shin splint group was significantly greater (P less than 0.01) at the heel strike. Further, the shin splints group had a significantly greater (P less than 0.01) angular displacement between the heel strike and the maximal everted position. The results suggest structural and functional differences in the feet and ankles between healthy athletes and those with shin splints.
