Pelvic movement strategies and leg extension power in patients with end-stage medial compartment knee osteoarthritis: a cross-sectional study.
During movement tasks, patients with medial compartment knee osteoarthritis use compensatory strategies to minimise the joint load of the affected leg. Movement strategies of the knees and trunk have been investigated, but less is known about movement strategies of the pelvis during advancing functional tasks, and how these strategies are associated with leg extension power. The aim of the study was to investigate pelvic movement strategies and leg extension power in patients with end-stage medial compartment knee osteoarthritis compared with controls. ⋯ Compared to controls, patients with medial compartment knee osteoarthritis use greater pelvic movements during advanced functional performance tests, particularly when these involve descending tasks. Further studies should investigate if it is possible to alter these movement strategies by an intervention aimed at increasing strength and power for the patients.

Case ReportsAcute neck pain caused by atlanto-axial instability secondary to pathologic fracture involving odontoid process and C2 vertebral body: treatment with radiofrequency thermoablation, cement augmentation and odontoid screw fixation.
Cervical spine metastases are relatively rare entities. Only about 10 % of all spinal metastases can be found in this localization. Magnetic resonance imaging and computed tomography are routinely used for early detection. The initial, clinical examination and patients' complaints may not always be very prominent. Treatment of such lesions is very challenging and needs to consider patient's comorbidities, quality of life and life expectation. Surgery for these lesions should always be performed in specialized spine units. ⋯ There are no specific guidelines regarding treatment of secondary lesions of C2 with instability at C1-C2 level. We describe here an interesting approach for the management of lytic lesions of C2 which may be used also at other levels of cervical spine. We did not observe any leakage of cement into the spinal canal. This procedure allows for fast recovery of patients, with early unrestricted range of motion, and beginning of early chemotherapy.

Case ReportsInverted distal clavicle anatomic locking plate for displaced medial clavicle fracture.
Fractures of the medial clavicle are rare injuries. Recently, open reduction and internal fixation has been recommended for displaced medial clavicle fractures in order to prevent non-union and dysfunction. ⋯ At the 12 months follow-up, the patient recovered well, had returned to pre-injury job, and was quite satisfied with the outcome. Internal fixation of medial clavicle fracture using an inverted distal clavicle anatomic locking plate of the ipsilateral side appears to be a good treatment option.

Case ReportsA rare case of bilateral proximal femoral insufficiency fractures after interlocking IM nailing for bilateral atypical femoral shaft fractures.
Atypical femoral fractures have unique radiologic and clinical feature. Most commonly used fixation method for atypical femoral fracture is interlocking intramedullary (IM) nailing. The aim of this paper is to document a rare case of a 76-year-old female who sustained bilateral proximal femoral insufficiency fractures after conventional interlocking IM nailing for bilateral atypical femoral shaft fractures without taking history of bisphosphonates. We recommend the routine use of full-length reconstruction or cephalomedullary-type interlocking IM nail for atypical femoral fractures.

A number of studies have examined the risk factors for Osgood-Schlatter disease (OSD). Studies on risk factors have not necessarily accurately demonstrated the risk factors of this disease because they were not prospective cohort studies or the populations in the studies were not categorized by the skeletal maturation of the tibial tuberosity. We can identify the precise risk factors for OSD by performing a prospective cohort study of a group of asymptomatic patients in particular times of adolescent using ultrasonography. In the present study, we aimed to investigate the precise risk factors for OSD. ⋯ This information may be useful for teaching quadriceps stretching in preadolescent male football players with stage I.
