Comparative StudyDorsal versus lateral plate fixation of finger proximal phalangeal fractures: a retrospective study.
Unstable proximal phalanx fractures are relatively common injuries but consensus of standard treatment is lacking. Outcomes following plate fixation are highly variable, and it remains unclear which factors are predictive for poorer results. The purpose of this study was to compare dorsal and lateral plate fixation of finger proximal phalangeal fractures with regard to factors that influence the outcome. ⋯ Therapeutic, retrospective comparative, level III.

Rotational acetabular osteotomy for acetabular dysplasia and osteoarthritis: a mean follow-up of 20 years.
Rotational acetabular osteotomy (RAO), a joint-conserving surgery in which the femoral head coverage by autologous cartilage is improved to achieve joint stability, is one of the most common joint-conserving surgeries for acetabular dysplasia of the hip in adult patients. Favorable outcome of RAO for pre- and initial coxarthrosis has been reported with middle- to long-term observation; however, surgery should be selected for advanced coxarthrosis. The objective of this study was to investigate the long-term clinical outcomes and radiological arthritis changes in patients who were treated with RAO and could be followed for 15 years or longer, and to investigate the joint conservation rate by preoperative arthritis stage. ⋯ The outcome of rotational acetabular osteotomy in most hips with pre- or initial coxarthrosis was satisfactory. Rotational acetabular osteotomy is an effective surgery for treating symptomatic developmental dysplasia of the hip in selected patients.

Does a foot-drop implant improve kinetic and kinematic parameters in the foot and ankle?
Unlike the drop foot therapy with ortheses, the therapeutic effect of an implantable peroneus nerve stimulator (iPNS) is not well described. IPNS is a dynamic therapy option which is placed directly to the motoric part of the peroneal nerve and evokes a dorsiflexion of the paralysed foot. This retrospective study evaluates the kinematics and kinetics in drop foot patients who were treated with an iPNS. ⋯ The results show statistically significant improvement in ankle dorsiflexion and vertical ground reaction forces. These facts indicate a more gait stability and gait efficacy. Therefore, the use of an iPNS appears an encouraging therapeutic option for patients with a stroke-related drop foot.

Factors affecting survival of patients in the acute phase of upper cervical spine injuries.
In recent years, on the one hand, the mortality rates of upper cervical spine injuries, such as odontoid fractures, were suggested to be not so high, but on the other hand reported to be significantly high. Furthermore, it has not been well documented the relationship between survival rates and various clinical features in those patients during the acute phase of injury because of few reports. This study aimed to evaluate survival rates and acute-phase clinical features of upper cervical spine injuries. ⋯ Elderly people were more likely to experience upper cervical spine injuries, and their mortality rate was significantly higher than that in injured younger people. In addition, complete paralysis, high ISS, a state of CPA at discovery, was significantly higher in the mortality group.

The accuracy of the lateral vertebral notch-referred pedicle screw insertion technique in subaxial cervical spine: a human cadaver study.
This is a cadaver specimen study to confirm new pedicle screw (PS) entry point and trajectory for subaxial cervical PS insertion. ⋯ The accuracy of the notch-referred PS insertion in cadaveric subaxial cervical spine is satisfactory.
