Surgical stabilization of humeral shaft nonunions can be difficult to achieve if severe osteopenia or loss of bone stock is present. We present a technique whereby a 4.5-mm standard dynamic compression plate is used in conjunction with a humeral cortical allograft strut and bone grafting to stabilize humeral shaft nonunions complicated by severe bone loss. ⋯ Union was achieved at an average of 3.4 months (range 2-6 months). Our method using onlay allograft struts can provide an effective alternative in the management of humeral shaft nonunion complicated by severe osteopenia of various etiologies.

Single incision open reduction and double plate fixation of complex tibial plateau fractures has been associated with high wound complication rates. Minimally invasive methods have been recommended to decrease the wound complication rates as compared with open techniques. Additionally, laterally applied fixed-angle devices appear to minimize late varus deformity without the need for additional medial stabilization. Accurate reduction of comminuted lateral and/or medial articular surfaces, however, often requires visualization through an open reduction. This study reports the complications, infection rate, and radiographic assessment of reduction associated with double plating complex AO/OTA 41-C3 tibial plateau fractures utilizing 2 incisions. ⋯ Comminuted bicondylar tibial plateau fractures can be successfully treated with open reduction and medial and lateral plate fixation using 2 incisions. Dysvascular limbs requiring vascular repair are at increased risk for deep sepsis. The use of 2 incisions, temporary spanning external fixation, and proper soft-tissue handling may contribute to a lower wound complication rate than previously reported.

Randomized Controlled Trial Comparative Study Clinical Trial
Biomechanical comparison of sacroiliac screw techniques for unstable pelvic ring fractures.
To determine the stiffness and strength of various sacroiliac screw fixations to compare different sacroiliac screw techniques. ⋯ Based on the results of this study, we can conclude that a second sacroiliac screw in completely unstable pelvic fractures increases rotation stiffness and improves the load to failure.

The purpose of this study is to determine the efficacy of reamed intramedullary nailing in the treatment of nonunions of the distal one-fourth of the tibia. Nonunions of the distal tibia are particularly difficult to treat given the short distal segment, the proximity to the ankle joint, and the fragile soft-tissue envelope. Intramedullary nailing is an attractive solution to this problem because it avoids extensive dissection, and the implant remains intraosseous, posing minimal problem for the soft tissues. ⋯ Reamed, locked intramedullary nailing is a reliable and safe procedure in the treatment of nonunions in the distal one-fourth of the tibia, even in the setting of prior infection or external fixation. It allows for excellent correction of deformity, which is an essential component of the procedure.

The purpose of this study was to determine the proximity of proximal interlocking mechanisms in 4 current antegrade humeral nails to the axillary nerve and its branches. ⋯ Nail SS's oblique locking screw may injure the ascending branch of the axillary nerve. Three of the 4 nails tested did not endanger the axillary nerve. However, when transverse proximal locking screws are inserted from a lateral-to-medial direction, they may endanger an arborized axillary nerve. Blunt dissection should be performed with a visible path to bone before instrumentation to reduce the risk of axillary nerve injury.
