Bone loss of the distal tibia represents a major challenge for the treating surgeons and the reconstruction technique. This is particularly true for septic bone loss. Several techniques are available, ranging from callus distraction of Ilizarov frames and monorail techniques as well as transport with plates and nails; however, implants for internal segmental transport for bone defects have so far not been available. This case report describes worldwide the first reconstruction of a distal tibial defect by reconstruction of the major arterial flow path with flap coverage and all inside segmental transport using a motorized segmental transport nail without additional osteosynthesis or add-on module.

Injuries of the thoracolumbar junction are the most common fractures of the spine due to their anatomical position and load. Common classification systems differentiate between stable and unstable injuries and thus also between operative and conservative therapy. The majority of injuries can be treated conservatively; however, unstable injuries require surgical treatment for a variety of reasons. ⋯ Hybrid procedures are also possible. This also applies to the treatment of osteoporotic fractures, since a clear assignment between traumatic and osteoporotic cause is not always easy and possible. This article describes the principles, the possible indications, and limitations of minimally invasive posterior and anterior stabilization.

Refixation with resorbable implants is a common surgical treatment in patients who suffer an injury with shearing of an osteochondral flake due to trauma of the knee or the upper ankle joint. To date there are no studies which outline long-term outcomes for this procedure. The aim of this study was to evaluate long-term clinical and magnetic resonance imaging (MRI) results after refixation with resorbable polylactide (PLLA) implants. ⋯ Because of good clinical and morphological results shown by MRI, refixation through resorbable implants (PLLA) can be recommended for treatment of traumatic osteochondral flakes.

Sacral fractures can be of traumatic origin and can also occur as insufficiency fractures. While the therapeutic target of mechanically stable insufficiency fractures is mainly pain relief, mechanically unstable insufficiency fractures and traumatic sacral fractures following high-energy trauma require biomechanical stabilization. Various surgical strategies are available for this, whereby minimally invasive techniques are now preferred whenever possible. ⋯ All surgical options have their indications. Nevertheless, the biomechanical stability which can be achieved differs widely. Therefore, an exact analysis should be carried out of what is necessary with respect to reduction and retention and what should be achieved when treating sacral fractures.

Isolated ruptures of the deep portion of the medial collateral ligament (MCL) without clinical instability can mostly be treated conservatively with good clinical results. A 10-year-old girl was initially also treated conservatively. ⋯ The patient showed complete resolution of the pain and a full range of motion of the knee joint. At the last follow-up 18 months after surgery the patient was completely free of symptoms.
