Comparative StudyFractures following radiotherapy and limb-salvage surgery for lower extremity soft-tissue sarcomas. A comparison of high-dose and low-dose radiotherapy.
The purpose of the present retrospective study was to determine the correlation between radiation therapy and the risk of postradiation fracture following combined therapy for the treatment of soft-tissue sarcomas of the lower extremity. ⋯ Women more than fifty-five years of age who are managed with removal of a thigh sarcoma combined with radiation therapy have a higher risk of pathologic fracture. The frequency of pathologic fractures associated with higher doses (60 or 66 Gy) of radiation is significantly higher than that associated with lower doses (50 Gy).

Radiographic analysis of the sagittal alignment and balance of the spine in asymptomatic subjects.
There is an increasing recognition of the clinical importance of the sagittal plane alignment of the spine. A prospective study of several radiographic parameters of the sagittal profile of the spine was conducted to determine the physiological values of these parameters, to calculate the variations of these parameters according to epidemiological and morphological data, and to study the relationships among all of these parameters. ⋯ This description of the physiological spinal sagittal balance should serve as a baseline in the evaluation of pathological conditions associated with abnormal angular parameter values. Before a patient with spinal sagittal imbalance is treated, the reciprocal balance between various spinal angular parameters needs to be taken into account. The correlations between angular parameters may also be useful in calculating the corrections to be obtained during treatment.

The spinoglenoid ligament. Anatomy, morphology, and histological findings.
Dysfunction of the distal branch of the suprascapular nerve has been reported in athletes involved in throwing or overhead sports. The consistent presence of a dynamic anatomic structure, the spinoglenoid ligament, overlying the nerve in the spinoglenoid notch may be a contributing factor to the dysfunction of this nerve. The purpose of this study was to report the anatomy, morphology, and histological characteristics of the spinoglenoid ligament. ⋯ This study revealed the presence of the spinoglenoid ligament in all of the shoulders that were examined, with some variation in the size of the ligament.

Documentation of acute compartment syndrome at an academic health-care center.
Documentation of the clinical course of a compartment syndrome is critical to effective treatment; however, such documentation often is found to be inadequate. ⋯ The documentation of the core history and physical examination findings was inadequate in this series of patients with compartment syndrome. On the basis of the results of this study, and through an organizational systems approach, we have instituted for our residents, nursing staff, and faculty an educational program on the documentation of compartment syndrome in patients who are at risk for this condition.
