The Peroneus Brevis Flap is a described option for the soft tissue coverage and for small bone gap reconstruction in the lower third of the lower leg, where few other local flaps are available and reliable. We analysed retrospectively a case series of 11 consecutive patients whose age ranged from 31 to 87 years (mean 56), who underwent a reconstruction with a PB flap in the treatment of post-traumatic bone infections from October 2010 to February 2012. ⋯ Main complications were partial flap necrosis or overlying skin graft necrosis, but without the need of secondary surgery. In our experience, the PB flap is a reliable option for soft tissue coverage in the treatment of distal leg and ankle osteomyelitis.

Vertical femoral neck fractures (Pauwels type III classification) in young adults generally occur as a consequence of high-energy trauma and are frequently seen in association with multiple injuries. Considering the controversies regarding the optimal fixation for this fracture, our aim was to evaluate the clinical outcome of a closed fixation strategy for vertical femoral neck fractures in young adults using two parallel and one transverse cancellous lag screws. This was a single-surgeon, prospective study including 20 young adults with average age of 38.75 years (range 18-59 years) with a high-energy Pauwels III femoral neck fracture. ⋯ After 24 months, bone union was achieved in 16 cases. Osteonecrosis of the femoral head developed in association with two fractures, and a nonunion developed in association with two fractures. We conclude that vertical high-energy femoral neck fractures can be treated successfully with internal fixation with two parallel cancellous lag screws positioned above the lesser trochanter and a third screw inserted centrally on the greater trochanter at an angle perpendicular to the fracture line.

Malignant neoplasms infiltrating the chest wall often requires resection of the thoracic wall. To replace the defect, Gore-Tex® is usually employed as the gold standard material, however, Gore-Tex® is inert and not degradable. Novel materials are nowadays available which allow a full bio-integration due to their non-toxic degradability. Additionally, stem cell seeding has the capacity to reduce inflammatory response towards such grafts, thus integrating it better into the host organism.

Implantation of a reverse total shoulder arthroplasty (rTSA) places the axillary and suprascapular nerves at risk. The aim of this anatomic study was to digitally analyse the location of these nerves in relation to bony landmarks in order to predict their path and thereby help to reduce the risk of neurological complications during the procedure. ⋯ Implantation of rTSA components endangers the axillary nerve because of its proximity to the humeral metaphysis and the inferior glenoid rim. Posterior and superior drilling and extraosseous screw placement during glenoid baseplate implantation in rTSA place the suprascapular nerve at risk, with safe zones to the nerve passing the spinoglenoid notch of 11mm and to the suprascapular notch of 19mm.

Posterolateral bone grafting to treat nonunions of the distal two-thirds of the tibia avoids the often traumatized and more tenuous anterior soft-tissue envelope. Few modern reports of its effectiveness are available. We assessed whether posterolateral bone grafting leads to high union and low complication rates. ⋯ Even in this relatively difficult patient cohort that included large bone gaps and history of infection, union was achieved at a relatively high rate with posterolateral bone graft. The approach seems to be safe, considering no known complications specifically associated with the approach occurred, and seems to reduce the risk of SSI in the absence of previous infection.
