Bone marrow edema (BME) syndrome represents a pathologic accumulation of interstitial fluid in bone - with a traumatic BME being differentiated from a non-traumatic, often ischemic, and a reactive as well as a mechanical BME. Atraumatic/ischemic BME is inconsistently described as a separate entity or as a reversible preliminary stage of osteonecrosis (ON). However, there is always the risk of transformation of BME into ON and subsequent joint destruction. ⋯ Infusion of prostacycline or bisphosphonates is a promising option. Ischemic BME and early stages of ON can be successfully treated by core decompression. A combination of both treatment options may also offer advantages.

Review Meta Analysis Comparative Study
[Subgroup-specific therapy of low back pain: description and validity of two classification systems].
In spite of profound advances in the diagnosis and therapy, low back pain (LBP) remains one of the main challenges for health systems in western industrialized countries. Clinical trials and meta-analyses typically show heterogeneous evidence and small effect sizes. One explanation for this phenomenon is the heterogeneous nature of the population of patients with LBP, not adequately considered in clinical practice and research. Recent studies and one meta-analysis show that therapy which is specifically directed at well defined subgroups leads to improved effectiveness of interventions, especially for non-surgical interventions such as manual therapy or physiotherapy. ⋯ The reliability of the described classification systems is moderate to good, aspects of validity have been shown. Their implementation in clinical practice seems recommendable.

Ankle fractures are the most frequent factures of weight-bearing joints in children while fractures of the hindfoot and midfoot are rare. Metatarsal fractures make up the greatest portion of foot fractures in children and mostly heal uneventfully. ⋯ Computed tomography scanning is most useful to precisely evaluate the degree of injury, especially articular involvement and to allow precise planning of the operative approach. Except for the calcaneus and the metatarsals the bones of the foot and ankle do not display a significant potential for spontaneous correction during growth; therefore, open reduction and internal fixation is indicated in all displaced fractures if closed reduction does not yield a satisfying result in order to avoid relevant post-traumatic deformities.

The minimally invasive subtalar screw arthroereisis procedure is becoming an increasingly more established option for treating juvenile flexible flatfoot. The procedure is indicated in children who are 9-13 years old and have idiopathic juvenile flexible flatfoot that has progressed to a symptomatic pathology. ⋯ This surgical intervention is contraindicated for treating fixed and secondary pes plano valgus. The subtalar screw is removed once the pediatric foot has stopped growing and results in permanent correction of the flexible flatfoot.

Deformities of the small toes often occur with complex forefoot deformities. Proximal interphalangeal joint arthrodesis is a reliable correction procedure for rigid flexed proximal interphalangeal joints. The most often performed technique by far is K-wire fixation; however, pin tract infections, malrotation due to deficient securing of the rotation and irritation of the metatarsophalangeal joints are common complications. ⋯ The follow-up time was 2 years. In all cases clinical and radiological osteotomy healing occurred 6 weeks postoperatively and there were no complications. This technically simple and cost-efficient procedure appears to be a good alternative to known proximal interphalangeal joint arthrodesis methods.
