INTRODUCTION Isolated proximal fibular stress fractures are rare and usually seen only in athletes and military recruits. Its occurrence with osteoarthritis of the knee is not documented. Diagnosis of stress fractures is not difficult, but they can mimic other pathologies at times. CASE REPORT A 45-year-old male patient presented with pain and paresthesias in left lower thigh and leg. He was ...
BACKGROUND AND PURPOSE The current definition of atypical femoral fractures (AFFs) associated with bisphosphonate use includes only de novo fractures. However, in recent years reports of bisphosphonate-associated periprosthetic fractures involving stemmed arthroplasty implants have emerged. In a case series of peri-implant fractures in femurs with plate/screw constructs, we aimed to assess simi...
Since hydraulic fractures exhibit a strong tendency to propagate in a plane normal to the least principal stress, the preferred plane of propagation under thrust stress regime (Sh > Sv) conditions is horizontal. This can lead to complications in applying the hydrofracture stress measurement technique as horizontal fractures do not directly sample the horizontal stress field. Recent experiences ...
Stress fractures, including both fatigue and insufficiency types, are frequently encountered in clinical practice as a source of pain in both athletes and patients with predisposing conditions. Radiography is the imaging modality of choice for baseline diagnosis. MRI has greatly improved our ability to diagnose radiographically occult stress fractures. Tc-99m bone scan and CT may also be useful...
BACKGROUND There is a large amount of information regarding risk factors for fifth metatarsal stress fractures; however, there are few studies involving large numbers of subjects. This study aimed to compare the static foot alignment and distribution of foot pressure of athletes with and without a history of fifth metatarsal stress fractures. METHODS The study participants comprised 335 colle...
Stress fractures of the fibula commonly occur distally in runners, whereas stress fractures of the proximal fibula are uncommon and typically occur in jumpers. Furthermore, it is rare for a stress fracture to be repeated in the same bone. We report a case of a repeated stress fracture of the proximal fibula in a male runner with abnormal gait that primarily involved excessive pronation. Unusual...
Bilateral pedicle stress fractures are rare even in the elderly. Bilateral pedicle fractures are due to post-surgical complications at the level of fusion or stress related activities in most cases. The authors describe a unique case of adjacent L4 bilateral pedicle fractures, which developed 4 years after anterior lumbar interbody fusion with bone cement augmented screw fixation at the L5-S1 l...
We describe two patients with diabetes mellitus and associated neuropathy, who presented with painless foot swelling and no history of trauma. X-Rays revealed recent underlying fractures-in one of a metatarsus, and the other of a proximal phalanx. These were assumed to be 'stress' fractures unassociated with pain because of the severe sensory neuropathy. Though spontaneous fractures in neuropat...
Upper extremity stress fractures, which are relatively rare, have become increasingly common, with olecranon stress injuries representing a subset primarily affecting throwing athletes. Olecranon stress fractures have been classified to fit specific radiographic patterns, with most of these injuries typified by a fracture line. Only a handful of olecranon stress injury cases report magnetic res...
To investigate the association of polymorphisms within candidate genes which we hypothesized may contribute to stress fracture predisposition, a case-control, cross- sectional study design was employed. Genotyping 268 Single Nucleotide Polymorphisms- SNPs within 17 genes in 385 Israeli young male and female recruits (182 with and 203 without stress fractures). Twenty-five polymorphisms within 9...
