Influence of screw design, sex, and approach in scaphoid fracture fixation.
Screw fixation of scaphoid fractures has gained popularity. A long central screw has been shown to be biomechanically advantageous. ⋯ Scaphoids in women are smaller than in men. Theoretically, fixation of scaphoid fractures through a volar approach will allow the surgeon to use longer screws. The screw design has a significant influence on the screw length that can be used in scaphoid fracture fixation. We recommend using a differential pitch screw with a thread diameter of 3.9 mm or less.

Combined anterior-posterior surgery is the most important risk factor for developing proximal junctional kyphosis in idiopathic scoliosis.
Several studies have identified risk factors for proximal junctional kyphosis (PJK) after instrumentation for scoliosis, but the relative risks are unclear. ⋯ Level III, prognostic study. See Guidelines for Authors for a complete description of levels of evidence.

Randomized Controlled TrialDoes ramosetron reduce postoperative emesis and pain after TKA?
Current pain management protocols involving many anesthetic and analgesic drugs reportedly provide adequate analgesia after TKA. However, control of emetic events associated with the drugs used in current multimodal pain management remains challenging. ⋯ Level I, therapeutic study. See the Guidelines for Authors for a complete description of levels of evidence.

Minimal epicondylectomy improves neurologic deficits in moderate to severe cubital tunnel syndrome.
Previous studies of minimal medial epicondylectomy for cubital tunnel syndrome included patients with mild disease, making it difficult to determine how much this procedure improved sensory and motor impairments in patients with moderate to severe disease. ⋯ Level IV, therapeutic study. See the guidelines for authors for a complete description of levels of evidence.

Comparative StudyLocal recurrence has only a small effect on survival in high-risk extremity osteosarcoma.
Tumor enlargement after chemotherapy is considered one of the high-risk factors for local recurrence and survival in osteosarcoma. We hypothesized patients with this risk factor will have similar survival regardless of the development of local recurrence. ⋯ Level III, prognostic study. See Guidelines for Authors for a complete description of levels of evidence.
