Outcome of transtrochanteric rotational osteotomy for posttraumatic osteonecrosis of the femoral head with a mean follow-up of 12.3 years.
This study examined the outcomes of applying transtrochanteric rotational osteotomy (TRO) for posttraumatic osteonecrosis of the femoral head (ON). ⋯ TRO to correct posttraumatic ON resulted in favorable midterm results. The possible risk factors for conversion to THA were an advanced preoperative stage and a postoperative intact ratio of less than 33.6 %.

Comparative StudyThe effects of the Frag-Loc(®) compression screw on distal radius fracture with a displaced dorsoulnar fragment.
The purpose of this study is to evaluate the radiographic and clinical outcomes of the Frag-Loc(®) compression screw with palmar plate fixation on distal radius fractures that include a displaced dorsoulnar fragment. ⋯ This study shows that the Frag-Loc(®) compression screw can reduce the gap distance between the dorsoulnar fragment and the distal radius, according to evaluation of post-surgical axial and sagittal CT scans. This result suggests that the Frag-Loc(®) compression screw is an effective and simple treatment option to immobilize a dorsoulnar fragment associated with distal radius fracture.

Arthroscopically assisted stabilization of displaced lateral clavicle fractures with coracoclavicular instability.
Lateral clavicle fractures associated with partial or complete injury of the coracoclavicular ligaments have traditionally been treated using a variety of open surgical techniques. ⋯ The arthroscopic-assisted and image intensifier-controlled closed reduction and single TightRope fixation with interfragmentary cerclage of displaced lateral clavicular fractures with coracoclavicular instability yields excellent clinical results and is able to recreate stability of the clavicle.

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.
