ABSTRACT
UNLABELLED: Traditionally, the opening base wedge osteotomy has been indicated in a moderate to severe hallux abducto valgus deformity with a short first metatarsal. This in vitro study aimed to address the question of how much lengthening is inherent to the geometric design of an opening wedge in the first metatarsal. The preosteotomy length of a first metatarsal segment was compared with postosteotomy length after performing transverse and oblique basilar osteotomies while maintaining the opening wedge with a prefabricated spacer. In the current bench study, it was found that the opening base wedge osteotomy does indeed lengthen the first metatarsal, albeit a small percentage of the total length (1%-2.8%), and there was no significant difference between the lengths achieved through a transverse or oblique osteotomy based on a confidence interval of 95%. LEVEL OF CLINICAL EVIDENCE: 5.

Charcot arthropathy, also known as neuroarthropathy, is most commonly associated with diabetes mellitus, despite a variety of other etiologies. A limited number of case reports have been published on neuroarthropathies caused by other forms of neuropathy, including alcoholic peripheral neuropathy. We report 4 cases of neuroarthropathy associated with chronic alcoholism in nondiabetic individuals. Conservative management similar to that afforded diabetic patients was successfully employed in these cases. A review of the clinical presentation and the pathology of alcoholic neuropathy is included in this report. ACFAS Level of Clinical Evidence: 4.
