“…Fractures of the lesser tuberosity of the humerus frequently occur in association with multi-part fractures of the humeral head and neck, often in the setting of dislocation [1 – 4] . Isolated fractures of the lesser tuberosity are more rare injuries, with an estimated incidence of 0.46 per 100,000 population per year [3] .…”

“…Isolated fractures of the lesser tuberosity are more rare injuries, with an estimated incidence of 0.46 per 100,000 population per year [3] . These have been described in 3 main types of injury: acute abduction/external rotation injury, chronic stress injury or acute injury in throwing or overhead adolescent athletes, and rarely acute injury on the basis of seizures (often in the setting of posterior fracture dislocation) [3] , [4] , [5] , [6] , [7] , [8] , [9] . The mechanism of injury in these cases has been thought to relate to traction effects of the subscapularis insertion upon the lesser tuberosity, either in resisting forced abduction/external rotation in acute trauma, exerting chronic or acute avulsive traction in the setting of adolescent overhead or throwing athletes, or undergoing violent contraction in the setting of seizures.…”

“…In contrast, the incidence of isolated greater tuberosity fractures was estimated to be 20% of all proximal humeral fractures [9]. The true incidence and misdiagnosis rates of isolated lesser tuberosity fractures may remain hidden as many injuries managed non operatively have satisfactory outcomes [5]. The high proportion of chronic cases reported in the literature suggest that they are often overlooked at the time of injury [4].…”

“…The diagnosis is commonly missed at initial presentation with a third of known cases having a delayed diagnosis [4]. The incidence of cases reported has increased in the past three decades [5]. This is likely due to the increased awareness of the injury along with improved use of clinical and radiographic examination by clinicians.…”
