The incidence of periprosthetic hip fractures is increasing due to the increase in endoprosthetic hip replacements. These fractures require a staged and individual treatment concept with the aim of mobilization of the patient as early as possible. The special challenge in the diagnostics is to identify pre-existing signs of loosening of the prosthesis. ⋯ Loosened stems usually have to be revised, mostly in combination with osteosynthesis. Fractures around the acetabulum with a fixed cup can be treated nonoperatively or with osteosynthesis, while loosened cups have to be revised. In revision surgery the stabilization of the dorsal column is crucial for a successful outcome.

[Deep posterior chronic exertional compartment syndrome as a cause of leg pain-German version].
A small proportion of patients with exertional leg pain (ELP) have deep posterior chronic exertional compartment syndrome (dp-CECS). These individuals report pain, tightness and cramps deep in the calf muscles that are elicited by exercise, but may also be present during rest to a lesser extent. Physical examination often reveals painful palpation of the flexor muscles in the area immediately dorsomedial to the tibial bone. ⋯ Various entities may mimic or coincide with dp-CECS, including medial tibial stress syndrome (MTSS) and popliteal artery entrapment syndrome (PAES). Fasciotomy of multiple flexor muscles is the only treatment that achieves a beneficial outcome. The aim of this overview is to discuss the diagnosis and management of dp-CECS.

Malnutrition in geriatric trauma patients is associated with an increased risk of complications and mortality and is therefore a key risk factor. The assessment of the affected patients plays an important role in improving the outcome of this growing patient group. ⋯ The establishment of suitable and time-effective screening instruments and their implementation are still a challenge.

The 3D image enhancer-adjusted percutaneous triangular stabilization of geriatric pelvic ring fractures avoids implant-associated perioperative complications. Displaced fractures of the posterior pelvic ring require stable instrumentation to enable solid bony fusion in a balanced alignment and to control the risk of neurological and vascular damage. This is mandatory in high-energy injuries in young patients and especially in low-energy injuries of geriatric patients. ⋯ After percutaneous insertion of the guide wires into the L4 vertebral body, the iliac bone and transiliosacrally under 2D X‑ray control, the correct wire position is verified by the 3D scan. Then, screws are inserted and the instrumentation is completed in a standard fashion. Using this technique implant-associated perioperative complications, such as nerve and vascular damage due to screw misplacement can be reduced.
