A fracture of the lateral margin of the distal tibia has commonly been called a Tillaux fracture, which is an avulsion-type fracture that can result from the pull of the anterior inferior tibiofibular ligament. The common mechanism of injury described and observed has been one of external rotation of the foot relative to the tibia. ⋯ We discuss 2 cases of isolated Tillaux fractures in skeletally mature adults, aged 47 and 37 years, a population in which this fracture pattern to our knowledge and after review of the published data has not been described. It is important to recognize these distinct injuries and appropriately treat the pathologic features to prevent further instability and arthritis.

Complex regional pain syndrome (CRPS) is an uncommon complication of orthopedic surgery, and few investigators have considered the incidence in foot and ankle surgery. In the present retrospective cohort study of 390 patients who had undergone elective foot and/or ankle surgery in our department from January to December 2009, the incidence of postoperative CRPS was calculated and explanatory variables were analyzed. A total of 17 patients (4.36%) were identified as meeting the International Association for the Study of Pain criteria for the diagnosis of CRPS. ⋯ Five of the patients (29.41%) were smokers, and 8 (47.06%) had had a pre-existing diagnosis of anxiety and/or depression. From our findings, we recommend that middle-age females and those with a history of anxiety or depression, who will undergo elective foot surgery, should be counseled regarding the risk of developing CRPS during the consent process. We recommend similar studies be undertaken in other orthopedic units, and we currently are collecting data from other orthopedic departments within Scotland.

The association of hyperglycemia with postoperative infectious complications after foot and ankle surgery has been well studied. However, many surgeons in their current practice use the somewhat arbitrary cutoff of 7% glycosylated hemoglobin (HbA1c) as the level above which surgery is considered unsafe and conducive to complications. Our goal in the present study was to assess the relationship between the HbA1c levels and the rate of postoperative infection to begin to determine whether 7% is a suitable cutoff or whether this level needs to be reevaluated. ⋯ Our preliminary, subjective, analysis has indicated that infection rates increase steadily as the HbA1c increases toward 7.3%, increase rapidly at an HbA1c of 7.3% to 9.8%, and then level off. Additional study is warranted to better understand the role played by other covariates in determining the infection rate and to investigate whether patient selection has influenced the appearance of decreased infection rates at high HbA1c levels. Additional study could also assess similar relationships for other types of complication, such as nonunion, and perhaps examine different foot and ankle procedures in isolation.

Fracture of the lateral process of the talus is a rare lesion commonly described in snowboarding injuries. Nevertheless, several conditions can lead to this injury, which is often misdiagnosed as a severe ankle sprain because of the difficulty in detecting it on standard radiographic views. Computed tomography is very helpful for the assessment of this injury. ⋯ In the 2 situations, we opted for an open reduction and internal fixation using 2.4-mm cannulated screws. Both patients were allowed walking with partial weightbearing with a walker boot (VACOped(®)) for 6 weeks. At 1 year, both showed a consolidated fracture and had regained their preinjury level of activity.

The purpose of the present study was to evaluate the factors contributing to the success of popliteal nerve blocks performed by podiatric surgical residents in various stages of training. A retrospective review was conducted of 143 consecutively performed blocks during a 2-year period. A total of 29 blocks using a lateral approach and 114 blocks using a modified posterior approach were performed. ⋯ No differences were observed between the success and failure groups with respect to the block approach or months of resident training. In conclusion, podiatric surgical residents in all stages of training can safely and effectively perform popliteal nerve blocks for peri- and postoperative analgesia. Surgeons should be aware of the potential influence of patients body mass index and age on the overall block success rates.
