Is there an Increase in Valgus Deviation in Tibial Distraction Using the Lengthening Over Nail Technique?
During tibial lengthening, the soft tissues of the posterolateral compartment produce distraction-resisting forces causing valgus angulation. Although this occurs with the classic Ilizarov method, whether a valgus deformity develops with the lengthening over nail (LON) technique is questioned, because the intramedullary nail is thought to resist deforming forces and adequately maintain alignment of the distracted bone. ⋯ Level III, therapeutic study.

Review Meta AnalysisReoperation After Cervical Disc Arthroplasty Versus Anterior Cervical Discectomy and Fusion: A Meta-analysis.
Anterior cervical discectomy and fusion is a standard surgical treatment for cervical radiculopathy and myelopathy, but reoperations sometimes are performed to treat complications of fusion such as pseudarthrosis and adjacent-segment degeneration. A cervical disc arthroplasty is designed to preserve motion and avoid the shortcomings of fusion. Available evidence suggests that a cervical disc arthroplasty can provide pain relief and functional improvements similar or superior to an anterior cervical discectomy and fusion. However, there is controversy regarding whether a cervical disc arthroplasty can reduce the frequency of reoperations. ⋯ Level I, therapeutic study.

Comparative StudyIs Arthroscopic Technique Superior to Open Reduction Internal Fixation in the Treatment of Isolated Displaced Greater Tuberosity Fractures?
Arthroscopic double-row suture-anchor fixation and open reduction and internal fixation (ORIF) are used to treat displaced greater tuberosity fractures, but there are few data that can help guide the surgeon in choosing between these approaches. ⋯ Level III, therapeutic study.

Randomized Controlled Trial Multicenter StudyDoes Teriparatide Improve Femoral Neck Fracture Healing: Results From A Randomized Placebo-controlled Trial.
There is a medical need for therapies that improve hip fracture healing. Teriparatide (Forteo(®)/ Forsteo(®), recombinant human parathyroid hormone) is a bone anabolic drug that is approved for treatment of osteoporosis and glucocorticoid-induced osteoporosis in men and postmenopausal women at high fracture risk. Preclinical and preliminary clinical data also suggest that teriparatide may enhance bone healing. ⋯ Level II, prospective study.
