ReviewTherapy-resistant complex regional pain syndrome type I: to amputate or not?
Amputation for the treatment of long-standing, therapy-resistant complex regional pain syndrome type I (CRPS-I) is controversial. An evidence-based decision regarding whether or not to amputate is not possible on the basis of current guidelines. The aim of the current study was to systematically review the literature and summarize the beneficial and adverse effects of an amputation for the treatment of long-standing, therapy-resistant CRPS-I. ⋯ The previously published studies regarding CRPS-I as a reason for amputation all represent Level-IV evidence, and they do not clearly delineate the beneficial and adverse affects of an amputation performed for this diagnosis. Whether to amputate or not in order to treat long-standing, therapy-resistant CRPS-I remains an unanswered question.

ReviewPediatric pedicle screws: comparative effectiveness and safety: a systematic literature review from the Scoliosis Research Society and the Pediatric Orthopaedic Society of North America task force.
Pedicle screws are widely used in spinal surgery. There is extensive published literature concerning the use of pedicle screw instrumentation for spinal surgery in adults. Now there is a trend to use pedicle screws in pediatric patients, including the very young. A systematic review of the current English-language literature on the use of pedicle screw instrumentation in the pediatric age group was performed to specifically determine (1) the pedicle screw placement accuracy in patients with spine deformity and (2) the effect size of all-pedicle screw constructs compared with other methods of spinal instrumentation in terms of the percentage of scoliosis correction. ⋯ The accuracy of pedicle screw placement in the pediatric spine exceeds the accuracy rate reported in adults. Pedicle screw instrumentation constructs are significantly more effective for scoliosis correction, as determined on the basis of Cobb angle measurements, than are hook constructs and hybrid constructs.

ReviewEvidence summary: systematic review of surgical treatments for geriatric hip fractures.
There is a growing body of literature on surgical treatments for elderly patients with a hip fracture and the effects of various surgical procedures on complications and postoperative outcomes. No single review has previously summarized the literature on the effects of surgical procedures on outcomes after treatment across all types of hip fractures. We conducted a comprehensive systematic literature review to organize the clinical evidence for patient-centered outcomes across all types of geriatric hip fractures. ⋯ The broader questions about the relationship of patient factors, fracture type, and specific treatments to the outcomes of mortality, functional status, and quality of life cannot be addressed with the existing literature. Research should include comprehensive conceptual models that capture complete sets of important independent variables. Studies of musculoskeletal outcomes, including hip fracture, require well-defined patient groups and consistent use of validated outcome measures.
