UNLABELLED Subchondral fracture of the femoral head has been reported to occur as an insufficiency fracture associated with poor bone quality or as a fatigue fracture in young military recruits. Transient osteoporosis of the hip has clinical and imaging findings that resemble those of a subchondral fracture, but it usually occurs in healthy middle-aged people not involved in sports or similar a...

Pelvic insufficiency fractures may occur in the absence of trauma or as a result of low-energy trauma in osteoporotic bone. With a growing geriatric population, the incidence of pelvic insufficiency fracture has increased over the last 3 decades and will continue to do so. These fractures can cause considerable pain, loss of independence, and economic burden to both the patient and the health c...

Low levels of serum vitamin D have been linked to numerous musculoskeletal and nonmusculoskeletal conditions. Vitamin D deficiency appears relatively high among various patient subpopulations, including patients with fracture nonunion. We conducted a retrospective study to determine the prevalence of vitamin D deficiency and insufficiency in a large population of patients with orthopedic trauma...

It is unclear if a decrease in cancellous bone density or cortical bone thickness is related to sacral insufficiency fractures. We hypothesized that reduction in overall bone density leads to local reductions in bone density and cortical thickness in cadaveric sacra that match clinically observed fracture patterns in patients with sacral insufficiency fractures. We used quantitative computed to...

We report a case of a stress fracture of the scapular spine which developed as a late complication of a reverse shoulder arthroplasty. After initially doing well after surgery, our patient developed pain and decreased shoulder function. A nondisplaced scapular spine fracture was noted on radiographs. Because reverse shoulder arthroplasty is a relatively new procedure in this country, radiologis...

The fifth meeting of the Ulster Medical Society for session 1937-38, was held in the Whitla Medical Institute on Thursday, 13th January, 1938. The president, Professor W. W. D. Thomson, occupied the chair, and the following interesting cinematograph films were shown: (a) Sufficiency and Insufficiency of the Mitral Valve. (b) Reduction and Treatment of Simple Fracture of the Leg. (c) Fracture of...
