The most common cause of degeneration of the posterior tibial tendon is a congenital valgus deformity of the calcaneus. Other associated pathologies are forefoot supination, forefoot abduction and shortening of the gastrocnemius muscle. ⋯ The correction of the hindfoot deformity as well as the subsequent treatment of the different components of the pathology lead to a significant improvement in foot function. Pre-existing degenerative alterations are limiting factors.

In unstable trochanteric fractures, the extramedullary rotationally stable screw-anchor (RoSA) combines the benefits of the load and rotational stability of the blade with the advantages of the screw (pull-out resistance, compression capability) in a single load carrier, and was designed to prevent femoral neck shortening by using an additional locked trochanteric stabilizing plate (TSP). ⋯ The fixation of unstable trochanteric femur fractures using the RoSA/TSP in a first clinical setting led to a great primary stability, with significant advantages with regard to limited femoral neck shortening. However, the rigidity of the construct with its consequences regarding bone healing can be challenging for the surgeon. Nevertheless, in some cases of revision it could be beneficial for stability.

Percutaneous internal fixation of pelvic fractures is increasing in popularity with multiple new techniques reported. ⋯ Percutaneous fixation of pelvic fractures requires high-quality imaging and can be aided by computer navigation. Safe techniques are reproducible; however, not all patients and fracture patterns can be treated using these techniques.

[Thoracolumbar spinal fractures in the elderly : Classification and treatment].
Thoracolumbar fractures in the elderly are frequently associated with osteoporosis. Osteoporosis can cause fractures or be a significant comorbidity in traumatic fractures. The OF classification is based on conventional X‑ray, computed tomography (CT) scan and magnetic resonance imaging (MRI). ⋯ The score takes the current clinical situation including patient-specific comorbidities into consideration. The treatment recommendations are based on an expert consensus opinion and include conservative and operative options. If surgery is indicated, vertebral body augmentation, percutaneous stabilization and even open surgery can be used.

Review
[Rupture of the tendon of the tibialis anterior muscle : Etiology, clinical symptoms and treatment].
Ruptures of the tendon of the tibialis anterior muscle tend to occur in the context of degenerative impairments. This mainly affects the distal avascular portion of the tendon. Owing to the good compensation through the extensor hallucis longus and extensor digitorum muscles, diagnosis is often delayed. ⋯ An operative procedure is indicated when there is corresponding suffering due to pressure and functional impairment. The direct end-to-end reconstruction of the tendon is only rarely possible in cases of delayed diagnosis due to the degenerative situation and the retraction of the tendon stumps. Depending on the defect size and the tendon quality, various operative techniques, such as rotationplasty, free transplants or tendon transfer can be used.
