Effect Modification and Interaction Terms: It Takes Two to Tango

July 1, 2016

In this Investigators’ Corner I look more deeply into the previously discussed phenomenon of effect modification. I revisit an explanation and examples of the phenomenon and then examine how to account for it statistically. Specifically, I show, in detail, how to write a regression equation that includes interaction terms that account for the effect modification

Consequences of Avulsion Fracture of the Proximal Phalanx Caused by a Technical Failure of Hallux Valgus Surgery

June 9, 2016

Several cases of avulsion fracture of the proximal phalanx of the big toe during the lateral capsular release procedure were observed. However, these fractures have not been reported as a complication of hallux valgus surgery. The purpose of the present study was to report the proximal phalanx base fracture as an unrecognized complication and to evaluate the clinical and radiographic consequences of this complication.

Posterior Ankle Structure Injury During Total Ankle Replacement

June 9, 2016

Total ankle replacement studies have focused on reporting complications that are directly observed clinically or radiographically, including wound problems, technical errors, implant loosening, subsidence, infection, bone fractures, and heterotopic ossification. However, patients can still experience unresolved pain even when these problems have been ruled out

Evaluation of Hallux Valgus Correction With Versus Without Akin Proximal Phalanx Osteotomy

June 8, 2016

Although the efficacy of Akin proximal phalanx closing wedge osteotomy as a sole procedure for correction of hallux valgus deformity is questionable, when used in combination with other osseous corrective procedures, the procedure has been believed to be efficacious.

Fever of Unknown Origin, Allergy to Titanium, and Hallux Valgus Surgery

June 7, 2016

The interesting and significant case study by Wang et al (1) adds further evidence of the relation between exposure to metals and fever of unknown origin. They reported the remarkable results with titanium removal in a young patient—an 18-year-old male—with pyrexia of unknown origin, possibly associated with exposure to the titanium alloy, which had been recently inserted and successfully placed as an ostheosynthesis surgical device for hallux valgus surgery (1). The investigators are to be commended for their important and well-executed case report.
