Parkinson disease is the second most common neurodegenerative condition. The literature on patients with Parkinson disease and spine surgery is limited, but increased complications have been reported. ⋯ Despite a higher rate of complications than in the general population, the overall outcome of spine surgery in patients with mild to moderate Parkinson disease is good, with improvement of spine-related pain. A larger prospective study is warranted.

Defining the "Three-Dimensional Sagittal Plane" in Thoracic Adolescent Idiopathic Scoliosis.
Obtaining accurate measurements of scoliosis from two-dimensional (2-D) radiographs can be challenging because of the three-dimensional (3-D) nature of the deformity. Previous studies have shown that the sagittal plane, in particular, is misrepresented on 2-D radiographs because of the influence of axial plane rotation. The purpose of the current study was to define a methodology for measuring the 3-D segmental sagittal alignment of the spine in patients with adolescent idiopathic scoliosis (AIS) and to assess the effect of axial plane rotation on differences between 3-D and 2-D measures of deformity. ⋯ Routine 2-D measurements of thoracic kyphosis erroneously underestimate the preoperative loss of kyphosis in AIS because of errors associated with axial plane rotation, an inherent component of thoracic scoliosis.

25-Hydroxyvitamin-D and Bone Turnover Marker Levels in Patients with Distal Radial Fracture.
Fragility fractures are a major public health issue with substantial socioeconomic cost. Vitamin-D deficiency and increased bone turnover are associated with higher rates of bone loss and an increased risk of fracture. We hypothesized that patients with a distal radial fracture would have lower levels of 25-hydroxyvitamin D (25[OH]D) and increased levels of serum bone turnover markers than controls without a fracture. ⋯ In this cohort, 25(OH)D levels were not associated with distal radial fracture and do not appear to affect the risk assessment for distal radial fracture in postmenopausal women. Patients with a distal radial fracture, however, had increased bone turnover as evidenced by high P1NP and osteocalcin levels. Women with both a high P1NP level and low bone mineral density were at particularly high risk for fracture.

Extensor Mechanism Injuries of the Knee: Demographic Characteristics and Comorbidities from a Review of 726 Patient Records.
The purpose of our study was to describe and compare extensor mechanism injuries with regard to age, sex, body mass index (BMI), and comorbidities. ⋯ Surgeons treating female patients with a tendinous extensor mechanism disruption should have a low threshold to initiate a medical work-up in search of a possible undiagnosed medical comorbidity.
