Clinical and radiological hip parameters do not precede, but develop simultaneously with cam morphology: a 5-year follow-up study.

Purpose: The aim of this study was to (1) investigate whether radiographic and clinical parameters, which influence how stresses during sporting activities act on the proximal femur, are associated with cam morphology or (2) precede cam morphology development.

Methods: Young male football players participated at baseline (n = 89, 12-19 years of age), 2.5-year (n = 63) and 5-year follow-up (n = 49).

The relationship between cam morphology and hip and groin symptoms and signs in young male football players.

Background: Conflicting and limited high-quality prospective data are available on the associations between cam morphology and hip and groin symptoms and range of motion (ROM).

Objectives: This cross-sectional cohort study investigated associations between cam morphology presence, size and duration and symptoms and ROM.

Methods: Academy male football players (n = 49, 17-24 years) were included.

Cam morphology in young male football players mostly develops before proximal femoral growth plate closure: a prospective study with 5-yearfollow-up.

Objectives: Cam morphology is not completely understood. The aim of this study was threefold: (1) to investigate if cam morphology development is associated with growth plate status; (2) to examine whether cam morphology continues to develop after growth plate closure; and (3) to qualitatively describe cam morphology development over 5-year follow-up.

Methods: Academy male football players (n=49) participated in this prospective 5-year follow-up study (baseline 12-19 years old).

A cam deformity is gradually acquired during skeletal maturation in adolescent and young male soccer players: a prospective study with minimum 2-year follow-up.

Background: A cam deformity is a major risk factor for hip osteoarthritis, and its formation is thought to be influenced by high-impact sporting activities during growth.

Purpose: To (1) prospectively study whether a cam deformity can evolve over time in adolescents and whether its formation only occurs during skeletal maturation and (2) examine whether clinical or radiographic features can predict the formation of a cam deformity.

Study Design: Cohort study (prognosis); Level of evidence, 2.

The development of Cam-type deformity in adolescent and young male soccer players.

Background: Cam impingement is a well-recognized cause of hip pain and might cause osteoarthritis of the hip. Clinically, cam impingement is mostly observed in young, active male patients, but only a few studies have focused on the manifestation of cam-type deformities during skeletal development.

Purpose: To determine the age of onset and prevalence of cam-type deformities in young male soccer players versus controls.

Correlation between radiological assessment of acute ankle fractures and syndesmotic injury on MRI.

Objective: Owing to the shortcomings of clinical examination and radiographs, injury to the syndesmotic ligaments is often misdiagnosed. When there is no indication requiring that the fractured ankle be operated on, the syndesmosis is not tested intra-operatively, and rupture of this ligamentous complex may be missed. Subsequently the patient is not treated properly leading to chronic complaints such as instability, pain, and swelling.

Magnetic resonance imaging for diagnosing lumbar spinal pathology in adult patients with low back pain or sciatica: a diagnostic systematic review.

Purpose: In about 5% of all cases LBP is associated with serious underlying pathology requiring diagnostic confirmation and directed treatment. Magnetic resonance imaging (MRI) is often used for this diagnostic purpose yet its role remains controversial. Consequently, this review aimed to summarize the available evidence on the diagnostic accuracy of MRI for identifying lumbar spinal pathology in adult low back pain (LPB) or sciatica patients.

Computed tomography for the diagnosis of lumbar spinal pathology in adult patients with low back pain or sciatica: a diagnostic systematic review.

Aim: In low back pain if serious pathology is suspected diagnostic imaging could be performed. One of the imaging techniques available for this purpose is computed tomography (CT), however, insight in the diagnostic performance of CT is unclear.

Method: Diagnostic systematic review.

Tibiofibular syndesmosis in acute ankle fractures: additional value of an oblique MR image plane.

Objective: To evaluate the additional value of a 45° oblique MRI scan plane for assessing the anterior and posterior distal tibiofibular syndesmotic ligaments in patients with an acute ankle fracture.

Materials And Methods: Prospectively, data were collected for 44 consecutive patients with an acute ankle fracture who underwent a radiograph (AP, lateral, and mortise view) as well as an MRI in both the standard three orthogonal planes and in an additional 45° oblique plane. The fractures on the radiographs were classified according to Lauge-Hansen (LH).

The additional value of an oblique image plane for MRI of the anterior and posterior distal tibiofibular syndesmosis.

Objective: The optimal MRI scan planes of collateral ligaments of the ankle have been described extensively, with the exception of the syndesmotic ligaments. We assessed the optimal scan plane for depicting the distal tibiofibular syndesmosis.

Materials And Methods: In order to determine the optimal oblique caudal-cranial and lateral-medial MRI scan plane, two fresh frozen cadaveric ankles were used.

The association between lumbar disc degeneration and low back pain: the influence of age, gender, and individual radiographic features.

Study Design: Cross-sectional open population based study (nested in a prospective cohort study).

Objective: To explore the association of the different individual radiographic features, including osteophytes and disc space narrowing, with self-reported low back pain (LBP). Different definitions of lumbar disc degeneration with self-reported LBP and disability were considered in a large open population sample.

Calcaneal fracture classification: a comparative study.

Unlabelled: Comparing different types of calcaneal fractures, associated treatment options, and outcome data is currently hampered by the lack of consensus regarding fracture classification. A systematic search for articles dealing with calcaneal fracture was performed, and the prevalence of use of each classification system determined. Twelve observers classified 30 intra-articular calcaneal fractures according to the 3 most prevalent classification systems; interobserver reliability (kappa [kappa] statistic) and the correlation of the system with the choice of treatment and clinical outcomes were calculated.

Effect of glucosamine sulphate on joint space narrowing, pain and function in patients with hip osteoarthritis; subgroup analyses of a randomized controlled trial.

Objective: Recently we reported that glucosamine sulphate (GS) did not have an effect on the symptoms and progression of primary care patients with hip osteoarthritis (OA). The aim of this present study was to investigate whether there are subgroups of patients with hip OA for whom GS might be an effective therapy.

Method: We randomized 222 patients with hip OA that met one of the American College of Rheumatology criteria to either 1500 mg of oral GS or placebo once daily for 2 years.

Costs and effectiveness of a brief MRI examination of patients with acute knee injury.

The aim of this study was to assess the costs and effectiveness of selective short magnetic resonance imaging (MRI) in patients with acute knee injury. A model was developed to evaluate the selective use of MRI in patients with acute knee injury and no fracture on radiography based on the results of a trial in which 208 patients were randomized between radiography only and radiography plus MRI. We analyzed medical (diagnostic and therapeutic) costs, quality of life, duration of diagnostic workup, number of additional diagnostic examinations, time absent from work, and time to convalescence during a 6-month follow-up period.

Effect of glucosamine sulfate on hip osteoarthritis: a randomized trial.

Background: The effectiveness of glucosamine sulfate as a symptom and disease modifier for osteoarthritis is still under debate.

Objective: To assess whether glucosamine sulfate has an effect on the symptoms and structural progression of hip osteoarthritis during 2 years of treatment.

Design: Randomized, controlled trial.

Value of information analysis used to determine the necessity of additional research: MR imaging in acute knee trauma as an example.

Purpose: To help guide future outcomes research regarding the use of magnetic resonance (MR) imaging in patients with acute knee trauma in an emergency department setting, with use of prospective data from a randomized clinical trial and value of information analysis.

Materials And Methods: A total of 189 patients (123 male, 66 female; mean age, 33.4 years) were randomly assigned to undergo radiography alone (n = 93) or radiography and MR imaging (n = 96).

Demographics of extra-articular calcaneal fractures: including a review of the literature on treatment and outcome.

Introduction: Extra-articular calcaneal fractures represent 25-40% of all calcaneal fractures and an even higher percentage of up to 60% is seen in children. A disproportionately small part of the literature on calcaneal fractures involves the extra-articular type. The aim of this study was to investigate the incidence of extra-articular calcaneal fractures in a Level 1 trauma centre, define the distribution of the various types of fractures and compare patient demographics between extra- and intra-articular calcaneal fractures.

Radiographic evaluation of calcaneal fractures: to measure or not to measure.

Objective: The aim of this study was to correlate the functional outcome after treatment for displaced intra-articular calcaneal fracture with plain radiography.

Design: The design was a prognostic study of a retrospective cohort with concurrent follow-up.

Patients: A total of 33 patients with a unilateral calcaneal fracture and a minimum follow-up of 13 months participated.

MRI for traumatic knee injury: a review.

Magnetic resonance imaging (MRI) is a well-established technique for detecting internal derangements of the knee joint with high diagnostic accuracy. It is an effective tool to select patients for targeted therapeutic arthroscopy. In this article, indications for knee MRI and most commonly used MRI techniques are outlined, followed by an overview of the most frequently encountered traumatic knee derangements in daily practice and their appearance and grading system on MRI.

Percutaneous treatment of displaced intra-articular calcaneal fractures.

Background: The outcome after displaced intra-articular calcaneal fractures is influenced by the condition of the surrounding soft tissues. To avoid secondary soft tissue complications after surgical treatment, several less-invasive procedures for reduction and fixation have been introduced. The percutaneous technique according to Forgon and Zadravecz is suitable for all types of displaced intra-articular calcaneal fractures and was therefore introduced in our clinic.

[A young woman with headaches and skull anomalies: a long road to the diagnosis 'Paget's disease'].

A 37-year-old woman complained of headaches, dizziness and squeaking noises in her right ear that had been going on for about 3 months. After experiencing tingling sensations in the left side of her body she consulted a neurologist, who ordered an MRI scan of her head, on which skeletal abnormalities consistent with multiple metastases of the skull were seen. Extensive clinical screening showed no evidence of a primary tumour.

Effects of ligament sectioning on the kinematics of the distal tibiofibular syndesmosis: a radiostereometric study of 10 cadaveric specimens based on presumed trauma mechanisms with suggestions for treatment.

Background: Syndesmotic injuries of the ankle without fractures can result from external rotation, abduction and dorsiflexion injuries. Kinematic studies of these trauma mechanisms have not been performed. We attempted to describe the kinematics of the tibiofibular joint in cadaveric specimens using radiostereometry after sequential ligament sectioning, and resulting from different trauma mechanisms and axial loading, in order to put forward treatment guidelines for the different types of syndesmotic injuries.
