Reconstruction of a bone defect using the Masquelet induced membrane technique has been well described. However, there are few reports of arthrodesis using this technique. In this case report, we describe a modified Masquelet technique for ankle arthrodesis with nailing. ⋯ At 1 year postoperatively, firm bony union was achieved and the implant was removed. At follow-up 3 years after his injury, the patient is able to walk, undertake physical work, and has no clinical signs of infection. Our experience suggests that a modified induced membrane technique may be useful when treating an open limb fracture with an extensive osteochondral defect where preservation of the joint is difficult and arthrodesis is considered.

Comparative Study
Acute shortening versus bone transport for the treatment of infected femur non-unions with bone defects.
The bone transport technique has been a well-known method in the treatment of osteomyelitis of the long bones with large segmental bone defects. However, one of the major drawbacks with this traditional technique is the long-lasting consolidation period, which may entail infectious and non-infectious complications. To overcome this drawback, several techniques were developed, one of which is acute shortening and re-lengthening. The aims of this study were: 1) to present our experience with a new modified technique of acute shortening and re-lengthening using a monolateral external fixator combined with a retrograde intramedullary nail, and 2) to compare its results with the classic Ilizarov bone transport method in the management of infected non-unions of the distal femur with bone loss. ⋯ Although both techniques could be employed safely in the treatment of infected non-union of the distal femur with size defects ranging between 3 cm and 10 cm, our modified technique of acute shortening and re-lengthening may confer greater patient satisfaction because of shorter EFI.

The effect of syndesmotic fixation on restoration of pressure mechanics in the setting of a syndesmotic injury is largely unknown. The purpose of this study is to examine the contact mechanics of the tibiotalar joint following syndesmosis fixation with screws versus a flexible fixation device for complete syndesmotic injury. ⋯ Either screws or TightRope fixation is adequate with AL alone. With lower amounts of torque, the TightRope group appears to have contact and pressure mechanics that more closely match native mechanics.

Observational Study
Delay in detection and treatment of perioperative anemia in hip fracture surgery and its impact on postoperative outcomes.
Elderly patients with hip fractures are at high risk for perioperative anemia as a result of fracture- and surgery-related blood loss. The detection of anemia is dependent on intermittent blood samples and therefore might be delayed, potentially leading to a significant delay in transfusion. This study aimed to investigate the possible delay in perioperative anemia detection, accumulated perioperative anemia-associated burden, peripheral perfusion, and their association with patient outcomes in elderly patients with hip fracture. ⋯ This study showed a delay in transfusion threshold detection, and the presence of significant associations between low SpHb or time with low SpHb and postoperative outcomes.
