Single-Stage Treatment of Fracture-related Infections.

SUMMARY: Fracture-related infections (FRIs) remain a significant problem. Many approach FRI cases in a staged fashion, focusing on infection eradication initially and fracture union during subsequent procedures. The literature quotes high success rates with this strategy. However, associated patient morbidity and economic impact are noteworthy. A single-stage FRI treatment, using an antibiotic-coated locked intramedullary nail, also exists. This video details low-cost, antibiotic-coated locked intramedullary nail fabrication in the operating room alongside preliminary results using this technique for acute FRI and septic nonunion treatment.

Long-term outcomes of allograft reconstruction of the anterior cruciate ligament.

Recent studies have found higher rates of failed reconstruction of the anterior cruciate ligament (ACL) with use of allograft when compared with autograft reconstruction. To evaluate the long-term outcomes of allograft ACL reconstruction, we retrospectively reviewed the cases of all patients who underwent allograft (n=99) or autograft (n=24) ACL reconstruction by 2 senior surgeons at a single institution over an 8-year period. Seventeen (17%) of the 99 allograft reconstructions required additional surgery. Reoperation and revision ACL reconstruction rates (30.8% and 20.5%, respectively) were much higher for patients 25 years of age or younger than for patients older than 25 years. In our cohort of NCAA (National Collegiate Athletic Association) Division I athletes, the revision ACL reconstruction rate was 62% for allograft ACL reconstruction and 0% for autograft reconstruction. Our study found that reoperation and revision rates for irradiated soft-tissue allograft ACL reconstruction were higher than generally quoted for autograft reconstruction. Given the extremely high graft failure rates in patients younger than 25 years, we recommend against routine use of irradiated soft-tissue allograft for ACL reconstruction in younger patients.

Biomechanical evaluation of suture-augmented locking plate fixation for proximal third fractures of the olecranon.

OBJECTIVES: To describe a method of suture augmentation of locking plate fixation (PF) of proximal olecranon fractures and to evaluate the biomechanical effectiveness of the suture augmentation using a human cadaveric model. METHODS: Six matched pairs of cadaveric elbows were used. Proximal one-third fractures of the olecranon were simulated via a transverse osteotomy. Identical locking PF was performed on each elbow using olecranon locking plates. One elbow of each pair was assigned to suture augmentation of the construct. The choice of left/right specimen for augmentation was performed in an alternating fashion. Augmentation was performed using a no. 2 ultra-high-molecular weight polyethylene-braided suture attaching the triceps to the plate via a modified Krackow stitch. The elbows were mounted into a custom jig and linearly loaded to failure using a hydraulic testing machine. Load to and modes of failure were recorded for each sample. The data were analyzed using the Wilcoxon signed-rank test for nonparametric distributions. RESULTS: Suture augmentation improved the single load-to-failure strength in all pairs. One pair was excluded due to failure of the triceps attachment to the test machine. A median 398 N (P = 0.04 range, 197-633 N) or a median 48% (range, 30%-130%) improvement in strength was seen. The most common mode of failure was loss of fixation of the proximal olecranon fragment. CONCLUSIONS: Suture augmentation can significantly increase the single load-to-failure strength of locking PF for proximal olecranon fractures.
