Locking plates are increasingly used to surgically treat proximal humerus fractures. Knowledge of the bone quality of the proximal humerus is important. Studies have shown the medial and dorsal aspects of the proximal humeral head to have the highest bone strength, and this should be exploited by fixation techniques, particularly in elderly patients with osteoporosis. ⋯ Strategic screw placement in the humeral head would minimize the possibility of loss of fracture reduction and potential hardware complications. Locking plate fixation is a good surgical option for the management of proximal humerus fractures. Complications can be avoided by using better bone stock and by careful screw placement in the humeral head.

The purpose of this study was to evaluate the surgical outcomes of reconstruction of chronic Achilles tendon ruptures using various methods, including Achilles tendon allograft. Between October 2003 and March 2010, twelve patients with chronic Achilles tendon ruptures and a defect gap of >4 cm underwent surgical reconstruction with V-Y advancement, gastrocnemius fascial turn-down flap, flexor hallucis longus tendon transfer, or Achilles tendon allograft. The study group comprised 11 men and 1 woman. ⋯ Seven patients were rated as excellent, 4 as good, and 1 as fair. Chronic Achilles tendon ruptures can be successfully treated by careful selection of the reconstruction method according to the length of defect gap and state of the remaining tissue. With an extensive defect, use of an Achilles tendon allograft can be a good option.

Randomized Controlled Trial
Does adding computed tomography change the diagnosis and treatment of Tillaux and triplane pediatric ankle fractures?
Computed tomography (CT) has been deemed a necessary part of management for Tillaux and triplane pediatric ankle fractures. However, no previously published study has attempted to quantify its usefulness in changing management. Six third-party, blinded orthopedic surgeons (F. ⋯ The addition of CT did not significantly change the impression of the amount of displacement per case. By adding CT, more patients who were assigned nonoperative management were reassigned to operative treatment (P=.033). Adding CT, although it may influence the decision to operate on Tillaux and triplane fractures, may not be as useful as previously thought.

Comparative Study
Role of autologous bone graft in the surgical treatment of atrophic nonunion of midshaft clavicular fractures.
A retrospective study was conducted to evaluate the role of autologous bone graft in treating atrophic nonunion of midshaft clavicle fracture with a limited-contact dynamic compression plate (LC-DCP). Between 1995 and 2008, sixty cases of atrophic nonunion of midshaft clavicle fractures were managed with open reduction and internal fixation with an LC-DCP. The cases were separated into 2 groups to evaluate the effect of autologous bone graft in the enhancement of bone union. ⋯ No statistically significant differences were found between the 2 groups regarding union time (average, 9.8 weeks in group 1 and 9.2 weeks in group 2) and postoperative functional scores (P>.05). Limited-contact dynamic compression plate fixation is an effective method for treating atrophic nonunion of midshaft clavicle fractures. Autologous bone graft was not needed.

The purpose of this study was to evaluate the effects of intraoperative fluid therapy on length of hospital stay and pulmonary complications in patients undergoing spine surgery. A total of 1307 patients were analyzed. Sixteen pulmonary complications were observed. ⋯ The best cutoff point for total fluids was 4165 mL, with a sensitivity of 0.8125 and specificity of 0.7171, for postoperative pulmonary complications. A direct correlation existed between fluids and length of stay: patients who received >4165 mL of total fluids had an average length of stay of 3.88±4.66 days vs 2.3±3.9 days for patients who received <4165 mL of total fluids (P<.0001). This study should be considered as hypothesis-generating to design a prospective trial comparing high vs low intraoperative fluid regiments for patients undergoing spine surgery.
