Relationship between tendon structure, stiffness, gait patterns and patient reported outcomes during the early stages of recovery after an Achilles tendon rupture.

After an Achilles tendon (AT) injury, the decision to return to full weightbearing for the practice of sports or strenuous activities is based on clinical features only. In this study, tendon stiffness and foot plantar pressure, as objective quantitative measures that could potentially inform clinical decision making, were repeatedly measured in 15 patients until 3 months after the AT rupture by using shear wave elastography (SWE) and wearable insoles, respectively. Meanwhile, patient reported outcomes assessing the impact on physical activity were evaluated using the Achilles Tendon Total Rupture Score (ATRS).

Expert Consensus on Predictive Parameters for the Occurrence of a Fall and a Contralateral Hip Fracture 1 and 3 Years After Hip Fracture: A Delphi Survey.

Background: Early identification of people at risk for a contralateral hip fracture would be desirable to favorably influence patients' prognosis. A recent systematic review failed to depict stringent patterns of risk parameters to be used for decision-making in clinical practice.

Objective: To perform a consensus study using the Delphi method to reach an expert consensus on predictive parameters for the occurrence of a fall and a contralateral hip fracture 1 and 3 years after hip fracture.

Significant Differences Between Local Reporting and Central Assessment of Radiographic Complications in a Prospective, Multicenter Study About Locking Plate Fixation of Proximal Humerus Fractures.

Objectives: To compare reporting outcomes of radiographic complications conducted by an independent review board and the responsible on-site study personnel in a multicenter study about locking plate fixation of proximal humeral fractures.

Design: Prospective, multicenter study; setting: 9 level I trauma centers.

Patients: One hundred fifty patients (age 50-90) with a radiographically confirmed displaced proximal humeral fracture fixed with a locking plate were included in the study.

Parameters Pointing at an Increased Risk for Contralateral Hip Fractures: Systematic Review.

Background: Early identification of hip fracture (HF) patients bearing an increased risk for a contralateral occurrence would allow providing preventive measures timely.

Objectives: To summarize the available evidence describing risk scores, prognostic instruments, or (groups of) parameters predicting contralateral HFs at the time point of the first fracture. Methods/Systematic Review: Articles were identified through searches in MEDLINE and Scopus from inception to April 2014, checking of reference lists of the included studies and reviews.

Significant differences between local reporting and central assessment of radiological complications in a prospective, multicenter study about locking plate fixation of proximal humerus fractures.

Objectives: To compare radiological complication reporting outcomes undertaken by an independent review board and the responsible on-site study personnel in a multicenter study about locking plate fixation of proximal humeral fractures.

Design: prospective, multicenter study SETTING:: Level I trauma centers PATIENTS:: One-hundred and fifty patients with a radiological confirmed, closed, displaced proximal humeral fracture fixed with a locking plate and aged between fifty and ninety years.

Intervention: Re-evaluation of all radiological data according to pre-defined criteria after finished collection of all study radiographs by an independent review board.

The effect of local bone mineral density on the rate of mechanical failure after surgical treatment of distal radius fractures: a prospective multicentre cohort study including 249 patients.

Introduction: The aim of this prospective, multicentre study was to evaluate the influence of local bone mineral density (BMD) on the rate of mechanical failure after locking plate fixation of closed distal radius fractures.

Materials And Methods: Between June 2007 and April 2010, 230 women and 19 men with a mean age of 67 years were enrolled. Dual energy X-ray absorptiometry measurements for BMD of the contralateral distal radius were made at 6 weeks post-surgery.

Biomechanical testing of rectangular humeral shaft prosthesis: higher torsional stability without increased fracture risk.

Background: Rectangular cementless femur shaft prostheses have a higher primary stability than round shafts. A novel rectangular humeral shaft design was tested with two questions: does the rectangular design cause a higher fracture risk during implantation than round designs, and does it increase the torsional stiffness?

Materials And Methods: Two series with six paired human humeri (total 24) were tested on one side with the rectangular shaft and on the contralateral side with a round shaft. In the first series, the shaft implantation was carried out with a constant speed of 100 mm/min and the maximum force was measured when the fracture occurred.

Mechanical stability in a human radius fracture treated with a novel tissue-engineered bone substitute: a non-invasive, longitudinal assessment using high-resolution pQCT in combination with finite element analysis.

The clinical gold standard in orthopaedics for treating fractures with large bone defects is still the use of autologous, cancellous bone autografts. While this material provides a strong healing response, the use of autografts is often associated with additional morbidity. Therefore, there is a demand for off-the-shelf biomaterials that perform similar to autografts.

Sports activity after anatomical total shoulder arthroplasty.

Background: Implant functionality has clearly increased over the past decades because of improvements in total shoulder arthroplasty systems. This means that prostheses are now being implanted in younger patients with high sports activity.

Hypothesis: The implantation of the total shoulder arthroplasty does not mainly influence the sports activity.

Reverse shoulder arthroplasty as a salvage procedure for failed conventional shoulder replacement due to cuff failure--midterm results.

Our goal was to evaluate the objective and subjective midterm outcome after revision of a failed shoulder arthroplasty with a reverse design prosthesis. Twenty consecutive patients with 21 revisions of a primary shoulder arthroplasty using reverse shoulder prosthesis Delta III(®) were followed up postoperatively for a mean of 46 months including clinical and radiological examination. Complications were recorded and Constant score, DASH and SF36 were assessed.

Challenges for Large Orthopaedic Hospitals Worldwide-An ISOC Position Statement.

Since the foundation of the International Society of Orthopaedic Centers in 2006, the group has continued to grow, with currently 11 members worldwide. During the 2008 annual meeting, the bylaws and mission of the group were approved as well as the acceptance of two additional members. Strict inclusion criteria were established to keep the group both small and effective.

Arthroscopic and open options for surgical treatment of chondromatosis of the elbow.

Purpose: The purpose of this study was to evaluate the treatment-specific outcome of surgical therapy of chondromatosis of the elbow with special attention on the complication and recurrence rate as well as induction of secondary osteoarthritis.

Methods: A consecutive patient group from 1989 to 2003 was evaluated retrospectively and followed up clinically and radiologically. Special attention was paid to locking and catching, swelling, pain, loose bodies, and signs of osteoarthritis.

Does Weber's rotation osteotomy induce degenerative joint disease at the shoulder in the long term?

Weber's internal rotation osteotomy of the humeral head is recommended for the treatment of anteroinferior shoulder instability with a large Hill-Sachs defect. The observation of severe joint degeneration in the course of long-term follow-up provided the motivation for this study. An osteotomy was performed in 42 patients from 1984 to 1990.
