Correction to: Insertion of the Ascension PyroCarbon PIP total joint in 152 human cadaver fingers: analysis of implant positions and malpositions.
In the experimental study the distal component of the Ascension PyroCarbon proximal interphalangeal total joint prosthesis was implanted 180° rotated. Figures 2-5 show the implant malpositions. The methods, results, and conclusion of the study were not affected by this.

Local effect of zoledronic acid on new bone formation in posterolateral spinal fusion with demineralized bone matrix in a murine model.
Posterolateral spinal fusion is a common orthopaedic surgery performed to treat degenerative and traumatic deformities of the spinal column. In posteriolateral spinal fusion, different osteoinductive demineralized bone matrix products have been previously investigated. We evaluated the effect of locally applied zoledronic acid in combination with commercially available demineralized bone matrix putty on new bone formation in posterolateral spinal fusion in a murine in vivo model. ⋯ A single local application of zoledronic acid with DBM putty during posterolateral fusion in sacral murine spine model increased significantly new bone formation in situ in our model. Therefore, our results justify further investigations to potentially use local application of zoledronic acid in future clinical studies.

Evaluation of donor site morbidity after medial triceps brachii free flap for lower limb reconstruction.
The medial head of the triceps brachii muscle (MTB)-free flap is an attractive solution to cover small-to-medium defects of the lower limb. This muscular head has no well-identified function, suggesting minimal impact of its removal on elbow mobility. The aim of this study was to evaluate the safety and reliability of the harvest procedure and the functional and cosmetic morbidity of this donor site. ⋯ Objective evaluation of patients who underwent an MTB-free flap for limb reconstruction shows no impact of the harvesting procedure on elbow extension. Patient satisfaction with the donor site was high. From this retrospective study, it appears that this surgery is safe, aesthetically acceptable, and has minimal impact on donor site elbow function.

Pain catastrophizing as a predictor for postoperative pain and opiate consumption in total joint arthroplasty patients.
Pain catastrophizing has been suggested as a prospective risk factor for poor postoperative pain outcomes in total joint arthroplasty (TJA). However, results from the previous studies have been mixed and have not controlled for postoperative opiate analgesic intake. This study investigates pain catastrophizing and postoperative pain intensity in TJA patients, adjusting for analgesic intake. We hypothesized that "pain catastrophizers" would exhibit higher pain scores and increased analgesic requirements postoperatively. ⋯ The pain catastrophizing scale is a poor predictor of postoperative pain at 3-month follow-up. However, it may be a risk factor for increased LOS.
