Rotational instability of the ankle joint in most cases has an injury of the lateral ligaments and a component of the deltoid, the TCL, but rarely with a combined lesion of the TCL and the anterior tibiotalar ligament (ATTL) (Superficial part of deltoid ligament complex). The combined lateral and medial ligament reconstruction with an anchor technique had a good clinical outcome with high patient satisfaction with few complications.
Degeneration of the acromioclavicular joint (AC) often causes impaired shoulder function and pain. Its infiltration results in reportedly beneficial short-term effects. Misplacement of infiltrations is observed in high numbers. A previous study showed high accuracy of infiltrations of one surgeon comparing conventional palpation technique to ultrasound guidance. This study evaluates if ultrasound-guided AC joint infiltration is feasible for therapists of different levels of experience and if the accuracy can be increased. One hundred and twenty AC joints of 60 cadavers were enrolled into a prospective, randomized observer-blinded study. Six therapists of three different levels of experience infiltrated 20 AC joints each. Half of them were infiltrated after palpation of the joint space, half of them were ultrasound-guided infiltrated. Controls were performed pre- and post-infiltration by an independent radiologist. In total, accurate infiltration was observed in 70%. In 25%, misplacement of the infiltration was recorded in the palpation-, in 2% in the ultrasound- and in 3% in both groups. The difference between the two groups was significant (P = 0.009). Ultrasound-guided infiltration to the AC joint is significantly more accurate than conventional palpation technique. This method is simple, efficient and can be applied by therapists of all levels of experience.
Preoperative anxiety can increase postoperative pain and is therefore important to avoid. Different approaches have already been tested for preoperative anxiolysis. Gabapentinoids might be a useful alternative to benzodiazepines. Pregabalin is used for treating generalized anxiety disorders and shows a favourable pharmacokinetic profile after oral administration; however, its anxiolytic effect preoperatively in healthy outpatients is still unclear. In this randomised, double-blind, placebo-controlled trial the anxiolytic effect of pregabalin in 40 outpatients undergoing standardised general anaesthesia and postoperative pain therapy for minor orthopaedic surgery was analysed. Patients received preoperatively either 300 mg pregabalin or placebo orally. The primary outcome was anxiety before anaesthesia induction, the secondary outcome the postoperative pain, both assessed using a visual analogue scale from 0 to 100. Without any side effects pregabalin reduced preoperative anxiety compared with the control group (23 ± 10 vs. 38 ± 17; p = 0.003). Pain scores did not differ between groups; however, need of piritramide in the postanaesthesia care unit was reduced to half by pregabalin compared with the control group. A single preoperative dose of 300 mg pregabalin reduces anxiety in patients undergoing minor orthopaedic surgery without any side effects like dizziness or persisting sedation resulting in a prolonged stay in the postanaesthesia care unit.
According to public opinion, Enduro motorcycling is a dangerous sport. Little is known about overuse injuries in connection with this sport. The study consisted of two phases. Phase 1 was planned as a prospective feasibility study for phase 2. The latter was initiated as a prospective investigation, comprising a random sample of the participants of phase 1. Enduro motorcyclists were interviewed with a prepared questionnaire. Clinical examinations were performed immediately before, and after, a major Enduro race, including pain assessment in the hand/wrist and the forearm using the visual analog scale. The occurrence of Raynaud's syndrome carpal tunnel syndrome (CTS), and loss of grip strength in the forearm muscles were recorded in detail. Phase 1 showed that the predominant overused anatomical regions were the hand/wrist and forearms. Nearly 50% of all the riders complained of pain or paresthetic sensations. A significant increase in pain was registered after the race. After the second run 32.28% of all riders had CTS in the left hand and 43.31% in the right hand. More than one-half of the athletes complained of overuse injuries. Transient CTS is an overuse injury closely related to sports.
In a retrospective single-centre study, 70 lowgrade chondrosarcoma (LCS) (31 female/39 male patients with a mean age of 40 years) were reviewed to evaluate surgical management. The mean overall follow-up was 81 months (median: 73 months, range: 6-317 months). Seventeen lesions (24.3%) in the trunk and 53 (75.7%) in the extremities were treated by curettage (48.6%) or resection (51.5%). Local recurrence occurred in eight patients (11.4%) 18 months postoperatively (median: 18 months, range: 0-41 months). Recurrence-free survival was significantly better for patients with extremity lesions compared to truncal lesions, but was not affected by resection margin. The anatomical site "trunk" and an "intralesional" resection margin had a significant independent prognostic influence in multivariate analysis. Curettage with local adjuvants is a viable treatment option for most extremity LCS. In truncal LCS wide resection is recommended despite a potentially higher complication rate.
Three-dimensional, computer-assisted navigation reveals significantly better results and is therefore recommended when extracorporeal shock wave therapy is used in the treatment of calcific tendinitis of the rotator cuff.
Low back pain is a very common disease but still a challenge to treat. Therapy strategies vary from conservative ones, pharmacological treatment with non-steroidal anti-inflammatory drugs (NSAIDs) and weak opioids, to invasive treatment with acupuncture, injections, and operative reconstruction. Some can be costly and not without risks. For instance, many people who use NSAIDs are at risk of common side effects such as gastrointestinal complications (irritation, ulcers, and bleeding) that may lead to hospitalization. Climbing could offer reduction of pain and better performance in daily life, because it offers a closed chain muscle training that has the potential to improve posture, perception of the trunk midline, and muscle control. Climbing may also lead to a better adherence to continuing treatment than traditional physical therapy and exercise due to a more exciting aspect of the sports activity.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
