The prevalence of carpal tunnel syndrome in adapted Sports athletes based on clinical diagnostic.

Background: Electrical studies are often used to diagnose carpal tunnel syndrome (CTS). We noticed differences in results when we considered the clinical tests.

Objectives: What's the prevalence of CTS in adapted sports athletes based on clinical diagnostic? Is there any relationship between the presence of symptoms and the use of wheelchairs, the type of sport practiced, dominance and how long the sport had been practiced?

Hypothesis: The prevalence of CTS in adapted sports athletes is close to that of the general population.

Evaluation of interobserver agreement in Albertoni's classification for mallet finger.

Objective: To measure the reliability of Albertoni's classification for mallet finger.

Methods: Agreement study. Forty-three radiographs of patients with mallet finger were assessed by 19 responders (12 hand surgeons and seven residents).

Percutaneous release of trigger fingers.

Open surgery has been indicated as the surgical treatment for trigger finger for many years; however, minimally invasive techniques are replacing conventional methods. Minimally invasive techniques enable early recovery of the patient with minimal damage to soft tissues. The authors’ study showed that levels of effectiveness of open surgical and percutaneous methods were superior to those of the conservative method using corticosteroid based on the cure and reappearance rates of the trigger.

Characteristics of global publications about wrist arthroscopy: a bibliometric analysis.

The objective of this study was to provide an assessment of published studies on the wrist arthroscopy. The search was performed from the "Web of Science (WoS) Science Citation Expanded Database" with studies published between January 1, 1990 and March 31, 2011. For research we used the following terms: "Wrist arthroscopy" and "Arthroscopy of the wrist".

Occupational musculoskeletal and mental disorders as the most frequent associations to worker's sickness absence: a 10-year cohort study.

Background: Sickness absence (SA) is a complex phenomenon influenced by the health of the worker and socio-economic factors. An epidemiological study of SA has never been conducted for Brazilian university workers. This study aimed to determine the main diseases that are associated with SA and find out the average length of SA duration, and its variation among different staff members and between sexes over the 10-year study period.

Treatment of trigger finger: randomized clinical trial comparing the methods of corticosteroid injection, percutaneous release and open surgery.

Objective: The aim of this study is to evaluate the effectiveness of CS injection, percutaneous pulley release and conventional open surgery for treating trigger finger in terms of cure, relapse and complication rates.

Methods: One hundred and thirty-seven patients with a total of 150 fingers were randomly assigned and allocated into one of the treatment groups, with treatments allocated into 150 opaque and sealed envelopes. We included patients >15 years of age with a trigger on any finger of the hand (Types II-IV) and used a minimum follow-up time of 6 months.

Overuse of training increases mechanoreceptors in supraspinatus tendon of rats SHR.

The presence of mechanoreceptors in tendon after overuse activities can be a further step to learn about tendinopathy and overuse. Studies of tendons mechanoreceptors in rats are rare. We studied 12 isogenic spontaneous hypertensive rats (SHR), which underwent an overuse protocol consisting of an hour per daily session of treadmill running at a speed of 17 m/min, 5 times/week for 4 months.

Anatomical study of the A1 pulley: length and location by means of cutaneous landmarks on the palmar surface.

Purpose: The objectives of this study were to evaluate palmar surface parameters to identify the exact location of the proximal edge of the flexor tendon A1 pulley relative to the digital palmar crease of the index, middle, ring, and little fingers and to evaluate the length of this pulley.

Methods: We studied 280 fingers on 70 hands from 35 fresh human cadavers, initially by measuring the distance between the digital-palmar and proximal interphalangeal creases (measure A), followed by dissection of the fingers and measurement of the distance between the proximal edge of the A1 pulley and the digital-palmar crease (measure B) and the length of the A1 pulley (measure C). We carried out statistical analysis using Hotelling's multivariate T(2)-test and the paired-samples t-test.

ARTHROPLASTY FOR TRAPEZIUM EXCISION AND TENDON INTERPOSITION IN RHIZARTHROSIS CASES: PROSPECTIVE STUDY.

Objective: To prospectively evaluate the results from a series of patients who underwent surgical treatment for rhizarthrosis using the technique of trapezium resection associated with interposition of yarn from the long abductor tendon of the thumb.

Methods: From May to August 2005, ten patients underwent surgical treatment for rhizarthrosis. Patients with primary osteoarthrosis of the trapezium-metacarpal joint, in stages II, III and IV of the Eaton classification, with persistent pain that was refractory to clinical treatment, were included.

Treatment of reducible unstable fractures of the distal radius in adults: a randomised controlled trial of De Palma percutaneous pinning versus bridging external fixation.

Background: At present, there is no conclusive evidence regarding the best treatment method for reducible unstable fractures of the distal radius. This study compared the effectiveness of two methods used in surgical treatment of such fractures: percutaneous pinning and external fixation.

Methods: We randomly allocated 100 patients into two groups treated surgically with modified De Palma percutaneous pinning and bridging external fixation.

Pectoralis major muscle rupture in athletes: a prospective study.

Background: In the past 20 years, there has been an increase in the incidence of upper extremity tendinous injuries, especially in sports including strong physical activity, such as in weight lifting, as well as with the concurrent use of anabolic steroids. Today, there are more than 200 cases describing rupture of the pectoralis major muscle in athletes.

Hypothesis: Surgical treatment will have a better outcome than nonsurgical treatment in total rupture of the pectoralis major muscle in athletes.

Outcome of diaphyseal forearm fracture-nonunions treated by autologous bone grafting and compression plating.

Background: The treatment of forearm fracture-nonunions continues to represent a therapeutic challenge, and reported outcomes are moderate at best. Limiting aspects of this particular anatomic location include the relation between restoration of shaft length with the anatomy and long-term functional outcome of adjacent joints, as well as the risk of elbow and wrist stiffness related to prolonged immobilization. The present study was designed to assess the outcome of autologous bone grafting with compression plating and early functional rehabilitation in patients with forearm fracture non-unions.

Are distal radius fracture classifications reproducible? Intra and interobserver agreement.

Context And Objective: Various classification systems have been proposed for fractures of the distal radius, but the reliability of these classifications is seldom addressed. For a fracture classification to be useful, it must provide prognostic significance, interobserver reliability and intraobserver reproducibility. The aim here was to evaluate the intraobserver and interobserver agreement of distal radius fracture classifications.

Fractures of the distal radius (Colles' fracture).

Context And Objective: Although Colles' fracture is a common clinical situation for the orthopedist, we did not find any information in the literature that would allow safe decision-making on the best treatment for each fracture type. The aim of the present study was to investigate Brazilian orthopedists' opinions regarding the main aspects of treatments for Colles' fracture.

Design And Setting: Cross-sectional study conducted during the 34th Brazilian Congress of Orthopedics and Traumatology.

Exact moment of tendon of pectoralis major muscle rupture captured on video.

A powerlifting athlete ruptured his left tendon of the pectoralis major muscle while attempting to lift 160 kg in a Brazilian bench press championship. The injury seemed to occur in the concentric phase of exercise; however, the more common mechanism of rupture is during the eccentric phase. The tendon was reinserted to the humerus 3 weeks later with screws and washers.
