ABSTRACT
The aim of this study was to report the incidence of arthrofibrosis of the knee and identify risk factors for its development following a fracture of the tibial plateau. We carried out a retrospective review of 186 patients (114 male, 72 female) with a fracture of the tibial plateau who underwent open reduction and internal fixation. Their mean age was 46.4 years (19 to 83) and the mean follow-up was16.0 months (6 to 80). A total of 27 patients (14.5%) developed arthrofibrosis requiring a further intervention. Using multivariate regression analysis, the use of a provisional external fixator (odds ratio (OR) 4.63, 95% confidence interval (CI) 1.26 to 17.7, p = 0.021) was significantly associated with the development of arthrofibrosis. Similarly, the use of a continuous passive movement (CPM) machine was associated with significantly less development of arthrofibrosis (OR = 0.32, 95% CI 0.11 to 0.83, p = 0.024). The effect of time in an external fixator was found to be significant, with each extra day of external fixation increasing the odds of requiring manipulation under anaesthesia (MUA) or quadricepsplasty by 10% (OR = 1.10, p = 0.030). High-energy fracture, surgical approach, infection and use of tobacco were not associated with the development of arthrofibrosis. Patients with a successful MUA had significantly less time to MUA (mean 2.9 months; sd 1.25) than those with an unsuccessful MUA (mean 4.86 months; sd 2.61, p = 0.014). For those with limited movement, therefore, performing an MUA within three months of the injury may result in a better range of movement. Based our results, CPM following operative fixation for a fracture of the tibial plateau may reduce the risk of the development of arthrofibrosis, particularly in patients who also undergo prolonged provisional external fixation.

Fractures of the head, neck, and body of the talus present difficult treatment challenges. The vulnerable blood supply and abundant articular surfaces may lead to long-term problems with osteonecrosis and osteoarthrosis. Previous studies of these relatively rare injuries have been mostly small, inconsistent, or anecdotal, leading to confusion and controversy regarding the optimum treatment of various types of talus fractures. The surgeon who treats these injuries must be prepared to address meticulous reduction and fixation, maintain attentive follow-up, and manage the complications that may result despite appropriate treatment. This review summarizes the findings of the literature on each type of talus fracture to provide a clearer picture of their recommended management.

We report a case history, treatment, and follow-up of an open comminuted distal tibial fracture with significant soft tissue loss and segmental loss of the tibial nerve and posterior tibial artery. This constellation of injuries with an insensate plantar foot has often been an indication for amputation. In this instance, a functional distal extremity was salvaged with the use of Ilizarov fixation, delayed primary tibial nerve cable grafting, and staged soft tissue coverage. Clinical follow-up and review of the literature on the techniques used are offered for consideration.

A 2-year-old male was found unresponsive approximately 40 min after oral exposure to butyrolactone (Figure 1), a solvent used to remove methacrylate glues. The patient was apneic, bradycardic, and flaccid. He was given atropine and orally intubated, and his heart rate increased and blood pressure remained normal. He remained unresponsive to deep painful stimuli. Six hours after admission, the patient was alert and breathing spontaneously. He was extubated and discharged home the following day. Previous cases of serious toxicity following oral exposure to butyrolactone reported in Denmark have shown a similar propensity to bradycardia and coma. The use of butyrolactone is likely to increase, paralleling the popularity of acrylate adhesives. Emergency physicians should be aware of its potential for life-threatening toxicity.
