Soft tissue defects of the foot are very common sequelae after trauma and require an individual reconstructive approach. ⋯ Precise preoperative reconstructive planning and analysis of the vascularization form the foundation for a successful soft tissue reconstruction of the foot. The aims of the individualized approach to soft tissue reconstruction of the foot are stable soft tissue coverage, resistance to weight bearing of the sole of the foot, the ability to wear normal shoes and maintenance of sensibility.

Traumatic nerve injuries are associated with a high morbidity and long rehabilitation times. The extent of a nerve lesion and the related regeneration potential can often only be estimated during the course, whereby the time window for successful surgical interventions is limited. ⋯ A strategic approach to conservative and surgical treatment of traumatic nerve injuries depending on the extent of injury and resulting regeneration potential is recommended. In conjunction with the clinical course, electrophysiology and imaging diagnostics, e.g. nerve sonography, can help to differentiate between neurapraxia, axonotmesis and neurotmesis.

A reliable reconstruction of soft tissue defects of the lower extremities especially in the distal third of the leg is still a special challenge for reconstructive surgeons. The possibility of salvaging the leg has to be evaluated in the setting of an interdisciplinary team and the timing of the operation(s) with respect to the safety of the patient and a systematic approach with the selection of a suitable flap have to be defined. ⋯ Recently perforator-based flaps have gained popularity for reconstruction of lower extremity defects. Furthermore, new surgical techniques and developments in association with the demographic change have led to a paradigm shift.

The treatment of patella fractures is technically demanding. Although the radiological results are mostly satisfactory, this often does not correspond to the subjective assessment of the patients. The classical treatment with tension band wiring with K‑wires has several complications. Fixed-angle plate osteosynthesis seems to be biomechanically advantageous. ⋯ The standard of care for patella fractures in Germany largely corresponds to the updated S2e guidelines. Tension band wiring is still the treatment of choice. Further (long-term) clinical studies are needed to verify the advantages of fixed-angle plates.

The success of a surgical procedure is significantly influenced by several critical factors. The safety of the patient is the primary goal. ⋯ Trauma surgery poses a particular challenge to preoperative preparation, especially due to urgent surgical interventions. Here, a standardized and evidence-based preoperative evaluation ensures a successful treatment of the patient.
