A modified Matti-Russe technique of grafting scaphoid non-unions.
In treatment of scaphoid non-union bone healing requires beside vital tissue and stability, enduring compression and a good interface between the graft and scaphoid fragments. While fixation techniques show a good primary stability, they reduce sintering and thus compression of fragments in the long term. Therefore, a modified technique optimising the cancellous interface between graft and scaphoid but still providing enough stability without fixating implants should be evaluated. ⋯ The modified technique of Matti-Russe provided a good contact of the cancellous part of the bone graft to the scaphoid in grafting a scaphoid pseudarthrosis with a high healing rate. However, since age, previous failed surgery and a proximal fracture line are the most important handicaps for bone healing in this study, for patients at risk gadolinium-enhanced MRI scan could be helpful to estimate vascularisation preoperatively. In cases of poor vitality, vascularised bone grafting should be considered.

Comparative StudyA comparison of apixaban and dabigatran etexilate for thromboprophylaxis following hip and knee replacement surgery.
Patients who have undergone hip or knee replacement surgery are exposed to a high risk of developing a post-operative venous thromboembolus and so have a need for an effective, medication-based, thrombosis prophylaxis. New orally active anticoagulants have been available for a few years now. These specific substances directly block either thrombin (e.g., dabigatran etexilate) or Factor Xa (e.g., apixaban). It is not clear whether there are any efficacy differences between these two substances because there have never been any head-to-head studies carried out. ⋯ Thus, it appears that the direct thrombin inhibitor, dabigatran etexilate, is associated with a longer period of wound secretion following the implantation of hip and knee endoprostheses than that associated with the Factor Xa inhibitor, apixaban.

Suprapectoral biceps tenodesis using a suture plate: clinical results after 2 years.
Several techniques for performing a tenodesis of the long head of biceps (LHB) are described. Only few outcome studies are published. This note describes a unicortical fixation via a suture plate-comparable to a distal biceps refixation-performed arthroscopically or mini-open via standard suprapectoral approach. The aim of this study is to show the clinical outcome after 6, 12, and 24 months. ⋯ Tenodesis of the LHB with a unicortical suture plate is a safe fixation technique with good-to-excellent clinical results after a minimum follow-up of 2 years. Long-term follow-up is needed.

The frequency of cartilage lesions in non-injured knees with symptomatic meniscus tears: results from an arthroscopic and NIR- (near-infrared) spectroscopic investigation.
Are symptomatic tear injuries to the menisci of the knee frequently or always associated with cartilage damage to the corresponding articular surfaces and other joint surfaces, respectively? ⋯ Through our investigations, a high, if not complete, concomitance of degenerative cartilage lesions and degenerative meniscus damage was demonstrated. From this it can be concluded that the entity of "isolated degenerative meniscus damage" clearly does not exist in practice. It is therefore highly probable that degenerative meniscus lesions, as a part of general joint degeneration, are to be interpreted in the context of the development of arthrosis. The practical consequences still are unclear. Patients after partial meniscectomy need a longer follow-up to detect potential cartilage lesions as well as an OA progression.

Prevalence and clinical features of sports-related lumbosacral stress injuries in the young.
Stress injuries (stress fractures and stress reactions) of the lumbosacral region are one of the causes of sports-related lower back pain in young individuals. These injuries can be detected by bone marrow edema lesion on MRI. However, little is known about the prevalence and clinical features of early stage lumbosacral stress injuries. This study aimed to evaluate the epidemiology of lumbosacral stress injuries. ⋯ MRI showed that 33.0% of the patients had lumbar stress injuries and 1.6% had sacral stress injuries. Lumbar stress injuries were more common in males than in females and were found in 30% of 13- to 18-year-old patients. About 50% of the patients that participated in soccer or track and field were diagnosed with lumbar stress injuries. No clinical patterns in the frequencies of sacral stress injuries were detected due to the low number of patients that suffered this type of injury. Plain radiography is rarely able to detect the early stage lesions associated with lumbosacral stress injuries, but such lesions can be detected in the caudal-ventral region of the pars interarticularis on sagittal computed tomography scans. Thirty-three percent of young patients that complained of sports-related lower back pain for ≥7 days had lumbar stress injuries, while 1.6% of them had sacral stress injuries. Clinicians should be aware of the existence of these injuries. MRI is useful for diagnosing lumbosacral stress injuries.
