The dynamics of proximal femoral nails: a clinical comparison between PFNA and Targon PF.
The objective of this study comparing the proximal femoral nails Targon PF (Aesculap, Tuttlingen, Germany) and Proximal Femoral Nail Antirotation (PFNA; Synthes. Oberdorf, Switzerland) was to observe the complications and postoperative results following pertrochanteric femoral fracture fixation, with special attention devoted to the dynamic properties of both implants under physiological load in vivo. The survey was designed as a randomized, prospective study of 80 patients who had sustained a pertrochanteric femoral fracture (AO type 31. ⋯ Both implants are suited to treat pertrochanteric femoral fractures and display comparable clinical results. The Targon PF demonstrates better dynamic properties than the PFNA under physiological load in vivo. A disadvantage of the Targon PF, however, is the more complicated surgical technique and the longer operative time.

Multicenter Study Comparative Study
Outcome of nonoperative vs operative treatment of humeral shaft fractures: a retrospective study of 213 patients.
Standard treatment for most humeral shaft fractures is nonoperative functional bracing; however, certain clinical scenarios necessitate operative intervention. There have been few studies in the literature comparing nonoperative and operative fixation of humeral shaft fractures. Two-hundred thirteen adult patients with a humeral shaft fracture who satisfied inclusion criteria were treated at 2 level 1 trauma centers with either a functional brace (nonoperative treatment group) or compression plating (operative treatment group). ⋯ No difference in time to union or ultimate ROM was found between the 2 groups. Closed treatment of humerus fractures had a significantly higher rate of nonunion and malunion while operative intervention demonstrated no significant differences in time to union, infection, or iatrogenic radial nerve palsy. Nonoperative management has historically been the treatment of choice for many humeral shaft fractures, however, in certain clinical scenarios these fractures may be well served by compression plating.

Comparative Study
Is obesity protective against wound healing complications in pilon surgery? Soft tissue envelope and pilon fractures in the obese.
Open treatment of pilon fractures is associated with wound healing complications. A traumatized, limited soft tissue envelope contributes to wound healing complications. Obese patients have larger soft tissue envelopes around the ankle, theoretically providing a greater area for energy distribution and more accommodation to implants. ⋯ Four occurred in the obese group (incidence 13%), and 4 in the lean group (incidence 5%) (P=.252). Ankle dimensions in clinically obese patients are larger than in lean patients. Obesity does not appear to be protective of wound-healing complications, but rather there is a trend toward the opposite.

Comparative Study
Surgical treatment of acute acromioclavicular joint injuries using a modified Weaver-Dunn procedure and clavicular hook plate.
Various surgical procedures have been described for the treatment of complete acromioclavicular joint dislocation, but no consensus exists on the optimal therapy. The aim of each type of procedure is to stabilize the clavicle by substitution of the ruptured coracoclavicular ligaments. Treatment modalities have changed with increasing understanding of the nature of the problem and the biomechanics of the joint. ⋯ The mean Disabilities of the Arm, Shoulder, and Hand (DASH) score was 12.2 points. Treatment of acute acromioclavicular joint injuries using a modified Weaver-Dunn procedure and a clavicular hook plate showed good short-term clinical results with a low complication rate. Further investigation and long-term results are needed to confirm these preliminary findings.
