Influence of Footwear on Posture and Comfort in Elite Rugby Players.

Influence of footwear on posture in athletes is poorly documented despite its potential impact on biomechanics and injury risk. The aim of this study was to investigate effects of different footwear geometries on comfort and posture on a cohort of 48 elite rugby players. Spine posture was characterized by photogrammetry, while center of pressure was measured by means of a force platform.

Increased performance in juvenile baboons is consistent with ontogenetic changes in morphology.

Objectives: In many primates, the greater proportion of climbing and suspensory behaviors in the juvenile repertoire likely necessitates good grasping capacities. Here, we tested whether very young individuals show near-maximal levels of grasping strength, and whether such an early onset of grasping performance could be explained by ontogenetic variability in the morphology of the limbs in baboons.

Material And Methods: We quantified a performance trait, hand pull strength, at the juvenile and adult stages in a cross-sectional sample of 15 olive baboons (Papio anubis).

Does autologous leukocyte-platelet-rich plasma improve tendon healing in arthroscopic repair of large or massive rotator cuff tears?

Purpose: To evaluate the clinical and magnetic resonance imaging (MRI) outcome of arthroscopic rotator cuff repair with the use of leukocyte-platelet-rich plasma (L-PRP) in patients with large or massive rotator cuff tears.

Methods: A comparative cohort of patients with large or massive rotator cuff tears undergoing arthroscopic repair was studied. Two consecutive groups of patients were included: rotator cuff repairs with L-PRP injection (group 1, n = 35) and rotator cuff repairs without L-PRP injection (group 2, n = 35).

Are multiple platelet-rich plasma injections useful for treatment of chronic patellar tendinopathy in athletes? a prospective study.

Background: Chronic patellar tendinopathy (PT) is one of the most common overuse knee disorders. Platelet-rich plasma (PRP) appears to be a reliable nonoperative therapy for chronic PT.

Purpose: To evaluate clinical and radiological outcomes of 3 consecutive ultrasound (US)-guided PRP injections for the treatment of chronic PT in athletes.

Anterior femoroacetabular impingement: an update.

Anterior femoroacetabular impingement can cause early hip osteoarthritis. The typical patient is an adult younger than 50 years of age, often with a history of sporting activities. The main symptom is intermittent pain triggered by static flexion (low seats) or dynamic flexion (during sporting or occupational activities that require repeated hip flexion).

Arthroscopic repair of full-thickness rotator cuff tears: is there tendon healing in patients aged 65 years or older?

Purpose: The aim of this study was to assess tendon healing and clinical results of rotator cuff tears (RCTs) repaired arthroscopically in patients aged 65 years or older.

Methods: Between January 2001 and December 2004, 88 patients with a mean age of 70 years (range, 65 to 85 years) had arthroscopic RCT repair. The repair was performed on 54 women (61%).

[Imaging in chronic low back pain: which one and when?].

Non-specific low-back pain (LBP) should de differentiated from symptomatic LBP, attributed to recognisable, known specific pathology (e.g. tumour, infection, inflammatory disease.

The time for functional recovery after arthroscopic rotator cuff repair: correlation with tendon healing controlled by computed tomography arthrography.

Purpose: We investigated how soon postoperative functional recovery became significant after arthroscopic rotator cuff repair and the influence of tendon healing.

Methods: We conducted a prospective study on 114 cases of full-thickness rotator cuff tears arthroscopically repaired from January 2001 to December 2003. All patients were evaluated by the Constant scoring system at 3, 6, 12, and 24 months after surgery and at last follow-up.

Prognostic value of early computed tomography in radiculopathy due to lumbar intervertebral disk herniation. A prospective study.

Objective: To prospectively evaluate the relationship between the early computerized tomography (CT) features of disk herniation and the clinical outcome in patients with recent-onset sciatic or femoral neuralgia treated conservatively. Early CT is often used, despite the absence of data on usefulness for predicting outcomes.

Methods: Of 78 patients with sciatica or femoral neuralgia of less than 1 month's duration, presumably due to a disk herniation, 75 were found by CT to have a disk herniation at the expected level.

Percutaneous Biopsy of Musculoskeletal Lesions.

Percutaneous biopsy is a minimally invasive technique that yields a high diagnostic accuracy at a relatively low cost in musculoskeletal lesions, especially tumors and infection. In this article, technical refinements improving the results of percutaneous biopsy of musculoskeletal lesions are reviewed, especially the type of radiological guidance, the different biopsy needles available, and the technique of approach depending on the lesion site. Reported complications, results, and indications of musculoskeletal percutaneous biopsy are also discussed.
