Hallux Pronation in Hallux Valgus: Experimental and Radiographic Study.

Toe pronation is a frequent sign in hallux valgus (HV), but it is difficult to assess and quantify. The aim of this study was to evaluate the relation between big toe pronation with both radiological and clinical findings and to determine if toe pronation is an influential factor in severity of HV. Six big toe donor proximal phalanges were used to create a radiographic calibrating system controlling their pronation at 0° to 60°.

Stereophotogrammetric surface anatomy of the anterior cruciate ligament's tibial footprint: Precise osseous structure and distances to arthroscopically-relevant landmarks.

Background: While femoral tunnel malposition is widely recognized as the main technical error of failed anterior cruciate ligament (ACL) surgery, tibial tunnel malposition is likely underrecognized and underappreciated.

Purpose: To describe more precisely the qualitative and quantitative anatomy of the ACL's tibial attachment in vitro using widely available technology for stereophotogrammetric surface reconstruction, and to test its applicability in vivo.

Methods: Stereophotogrammetric surface reconstruction was obtained from fourteen proximal tibias of cadaver donors.

In vivo bactericidal efficacy of the Ti6Al4V surface after ultraviolet C treatment.

Background: Biomaterial-associated infections are one of the most important complications in orthopedic surgery. The main goal of this study was to demonstrate the in vivo bactericidal effect of ultraviolet (UV) irradiation on Ti6Al4V surfaces.

Materials And Methods: An experimental model of device-related infections was developed by direct inoculation of Staphylococcus aureus into the canal of both femurs of 34 rats.

Severe post-burn hyperextension of metatarsophalangeal joints in a child with bilateral foot contracture.

Achieving a stable plantigrade foot after repair of complex post-burn deformities poses a particularly difficult challenge for the foot and ankle surgeon. We report an unusual case of a child with severe bilateral forefoot contracture deformities treated by soft tissue release and lengthening, and conventional wound coverage with split-thickness skin grafting.
