Titanium acetabular cementless cups combined with highly crosslinked polyethylene liner have very low rates of aseptic loosening.

Background: There is a clear tendency towards cementless acetabular components in primary total hip arthroplasty.

Objective: The aim of this study was to assess the long-term clinical and radiological outcome of titanium cementless acetabular cups when combined with a highly crosslinked polyethylene liner.

Methods: This study is a retrospective follow-up of 67 cups in 64 patients.

Factors affecting blood loss and blood transfusion in patients with proximal humeral fractures.

Background: The aim of this study was to determine the amount of blood loss and the rate of blood transfusion in patients receiving surgery for proximal humeral fractures depending on the treatment and fracture classification. Moreover, factors associated with blood loss and blood transfusion were analyzed.

Methods: The study included 420 patients who had received surgery for proximal humeral fractures.

Surgical revision of radial head fractures: a multicenter retrospective analysis of 466 cases.

Background: Radial head fractures lead to persisting disability in a considerable number of cases. This study aimed to investigate their most common revision causes and procedures.

Methods: This multicenter retrospective study reviewed the cases of 466 adult patients who had undergone surgical revision after operative or nonoperative treatment of a radial head fracture.

Prospective randomized controlled trial in the treatment of lateral epicondylitis with a new dynamic wrist orthosis.

Background: In the treatment of lateral epicondylitis (LE), the role of a new dynamic wrist orthosis is unclear.

Patients And Methods: Patients suffering from a LE longer than 3 months were multicentrically and prospectively randomized into a physiotherapeutic group (PT group) and in a physiotherapy group plus wrist orthosis (PT + O group). Physiotherapy consisted of daily eccentric strengthening exercises under initial professional supervision.

Differences in total blood loss and transfusion rate between different indications for shoulder arthroplasty.

Purpose: In this study, the total blood loss, transfusion rate and number of transfused blood units in patients with different indications for shoulder arthroplasty: primary, fracture and secondary were compared. Risk factors for bleeding and transfusion were analysed.

Methods: Medical records and the database of the institution's blood bank from 527 patients that received shoulder arthroplasty were analysed retrospectively.
