The tension of the iliopsoas tendon more than doubles during extension of the dysplastic hip in open reduction.

The role of the iliopsoas as an obstructing and re-dislocating factor in developmentally dislocated hips is unclear. The purpose of this article is to determine the change in the iliopsoas' tension during flexion and extension when performing an open reduction. We evaluated 34 hips undergoing an anterior open reduction for a developmental dislocation.

Acute complex instability of the elbow treated with internal joint stabilizer IJS-E System.

Introduction: Treatment of acute complex fracture-dislocation of the elbow has been associated with a high rate of complications. Internal Joint Stabilizer of the Elbow (IJSE) device appears as a valid option to optimize and improve our results.

Material And Methods: We present a retrospective case series of five patients treated at our institution with IJS-E System (Skeletal DynamicsR) from February 2019 to 2020.

Does the fracture of the lateral wall affect the degree of collapse and the degree of sliding of the cephalic plate, in pertrochanteric fractures treated by intramedullary interlocking? Radiological study and review of the literature.

Background: Lateral wall fracture has been recognized as an important sign of instability of pertrochanteric fractures. The aim of the present study is to assess the relationship between lateral wall fractures, helical blade telescoping and neck shortening in fractures treated with intramedullary nailing.

Material And Method: A descriptive radiological study was performed at our institution.

Primary total hip arthroplasty in elderly patients over 85 years old: risks, complications and medium-long term results.

Introduction: The elderly population candidate for total hip arthroplasty (THA) is increasing exponentially in developed countries, due to the high prevalence of osteoarthritis (OA). The objective is to identify the overall survival in patients over 85 years with primary OA who underwent THA.

Material And Methods: Retrospective observational study in patients over 85 years with primary hip OA undergoing THA between 2012 and 2019.

[Mid-term complications of the monopolar, modular radial head prosthesis].

Introduction: The objective of this study is to assess the type, frequency and severity of complications after the implantation of the modular monopolar radial head prosthesis.

Material And Methods: Forty-seven patients with 48 radial head prostheses implanted between 2009 and 2017 were reviewed retrospectively. Patients were evaluated clinical and radiographically for a mean follow-up of 43.
