Case Reports
Definitive treatment of bilateral acetabular and pelvic ring injuries using external fixation.
Bilateral pelvic ring and acetabular fractures are rare injuries. The optimal treatment of these patients and their outcomes remain largely unknown. We present a three year follow up of a case of bilateral posterior pelvic ring injuries and acetabular fractures treated successfully with limited internal fixation and external fixation.

Randomized, controlled study in a laboratory setting. Blinded observations/assessment of study outcomes. ⋯ In this commonly used rabbit posterolateral fusion model, Mastergraft(®) Strip with BMA in an autograft extender mode produces biomechanical and radiographic results similar to autograft fusion alone.

Numerous studies have examined the elution characteristics and the effects of antibiotics from bone cement. this study seeks to determine the effect that surface area and volume have on the elution characteristics and bioavailability of tobramycin and vancomycin when mixed in polymethylmethacralate (PMMA) bone cement in various combinations. It also investigates the mechanical properties of antibiotic-impregnated bone cement and its relationship to surface area and volume. ⋯ This study advanced our overall understanding of the elution characteristics and biomechanics of PMMA bone cement impregnated with tobramycin and vancomycin.

The deltoid ligament is the primary ligamentous stabilizer of the ankle joint. Both superficial and deep components of the ligament can be disrupted with a rotational ankle fracture, chronic ankle instability, or in late stage adult acquired flatfoot deformity. The role of deltoid ligament repair in these conditions has been limited and its contribution to arthritis is largely unknown. ⋯ Newer tenodesis techniques have been described for late reconstruction of both deep and superficial components in patients with stage 4 adult acquired flatfoot deformity. We describe a technique that provides anatomic ligament-to-bone repair of the superficial and deep bundles of the deltoid ligament while reducing the talus toward the medial malleolar facet of the tibiotalar joint with anchor-to-post reinforcement of the ligamentous repair. This technique may protect and allow the horizontally oriented fibers of the deep deltoid ligament to heal with the appropriate resting length while providing immediate stability of the construct.

Peripheral nerve blocks (PNB) are a common adjuvant for anesthesia. There is little orthopedic literature regarding the incidence of neurogenic complaints and quality of pain control. ⋯ Cohort study type III.
