Case ReportsSacral insufficiency fracture, an unsuspected cause of low-back pain in elderly women.
Sacral insufficiency fractures (SIF) usually occur in elderly women and are secondary to various conditions, mainly postmenopausal or steroid-induced osteoporosis and radiation therapy. They are often overlooked or confused clinically and radiographically with metastatic disease. We report a case of a 72-year-old woman who presented to our department with severe low-back pain. ⋯ Computed tomography (CT) confirmed sclerotic changes interpreted as insufficiency fractures through both sacral alae. Increased awareness of these fractures may help to avoid unnecessary investigations and treatment. Bed rest and analgesia followed by rehabilitation provide good relief of symptoms.

Malignant lymphoma of bone is rare. In many cases, its diagnosis is delayed because of unspecific clinical signs and equivocal radiographs. Therapy in general is multimodal, including surgery and radio- and chemotherapy. ⋯ Treatment generally is conservative, based on the stage of the disease. Local radiation with or without systemic chemotherapy should be used. The long-term survival is favorable, but dependent on the stage of the disease and the amount of bone involvement.

Comparative StudyAdjacent segment degeneration after lumbar spinal posterolateral fusion with instrumentation in elderly patients.
This retrospective study investigated adjacent segments radiologically and clinically after posterolateral fusion of the lumbar spine with instrumentation. Thirty-two patients over 60 years old with a postoperative follow-up of at least 4 years were included. These patients all met the criteria of a postoperative symptom-free period of over 2 years, evident fusion mass seen on plain radiographs, and no implant breakage or loosening. ⋯ However, no statistically significant difference (p = 0.7878) was found according to the Fisher exact test. Comparing the effect of different types of instruments, there still was no statistically significant difference (p = 0.1161) between the VSP plate and Isola rod groups in inducing degeneration of adjacent segments after posterolateral fusion of the lumbar spine. After measuring the mobility of degenerated adjacent segments, relative hypermobility was more likely responsible for the accelerated degeneration rather than the absolute increase of mobility.

Case ReportsFatal retroperitoneal hemorrhage caused by perforation of a guidewire pin for proximal femur fixation.
A 77-year-old woman with a slightly displaced intertrochanteric two-fragment fracture of the left hip was treated by internal fixation using a screw-nail device (gamma nail). After the operation she became hemodynamically unstable, and ultrasound revealed a large retroperitoneal fluid accumulation in the left lower abdomen. ⋯ However, despite the successful treatment of the retroperitoneal hemorrhage, the patient developed an oligosymptomatic myocardial infarction associated with clinical evidence of a cerebrovascular insult and pulmonary decompensation and died 2 weeks after her accident. The hemorrhage in this patient was most likely caused by surgical damage to the obturator artery during placement of the guidewire pin (with threaded tip) to position the screw of the implant.

Comparative StudyHumeral shaft fractures as predictors of intra-abdominal injury in motor vehicle collision victims.
To assess the utility of humeral shaft fractures as predictors of organ injuries and skeletal injuries in multiply injured patients involved in motor vehicle collisions (MVCs). A prospectively collected database of multiply injured motor vehicle occupants with an Injury Severity Score (ISS) greater than 12 admitted to a level I regional trauma centre during a 102-month period (January 1992 to June 2000) was reviewed to assess skeletal and organ injuries associated with a humeral shaft fracture. The effect of occupant location within the vehicle, the point of collision, and the use of a seat belt restraint was also examined to identify trends in injury patterns. ⋯ A lateral collision impact showed a trend towards increased splenic and hepatic injuries within the humeral shaft fracture group. The presence of a humeral shaft fracture in a multiply injured patient involved in a MVC is significantly associated with an increased incidence of both upper and lower extremity fractures and liver injury. Moreover, humeral shaft fractures may serve as a predictor of potential intra-abdominal pathology in multiply injured trauma patients involved in MVCs.
