The Impact

(1) Background: Reconditioning of the paraspinal lumbar extensor muscles by isolated lumbar extension resistance exercises (ILEX) has shown good clinical results for patients with chronic unspecific low back pain. However, the clinical value and safety for patients with specific spine pathologies is unclear. In this study, clinical outcome and influencing factors were retrospectively analyzed for patients with lumbar disk herniation (LDH) and radiculopathy. (2) Methods: 189 consecutive patients (123 men and 66 women; mean age, 36 years) with clinically diagnosed LDH and relative indications for surgery started a 9-week rehabilitation program (2x/week) including ILEX in limited range of motion (ROM) adjusted to patients’ symptoms. Patients diagnosed with advanced levels of spine degeneration were excluded. Pain/radiculopathy (PR), influence on mental health (IOMH), satisfaction rates were measured via Numeric Rating Scales (NRS, 0–10), and overall clinical outcome was stated in % (100% = full recovery). Isometric extension strength was tested before and after the program. (3) Results: 168 patients (88.9%) completed the program. For 162 out of 168 patients (96.4%) there was a significant reduction of clinical symptoms, whereas 6 patients reported no changes in symptoms. Scores (mean) for symptom intensity decreased from 4.2 (±1.5) to 1.9 (±1.5) (p < 0.001), the impact on mental health decreased from 5.9 (±2.3) to 2.4 (±2.0) (p < 0.001). There was a (weak) correlation between lower scores for PR and IOMH before the study and better clinical outcomes; PR also weakly correlated with satisfaction. Other factors such as age, strength increase, level/location and number of LDH did not have a significant impact on the clinical results. (4) Conclusion: The results indicate that ILEX in limited ROM can be an effective treatment for the majority of patients with LDH. For patients with high pain levels, the results are less consistent, and surgery may be considered.

The Impact

Livestock production significantly contributes to emissions of polluting gases emissions like ammonia (NH<sub>3</sub>) and greenhouse gases. Pig production is globally responsible for about 15% of ammonia emissions. The aims of this paper were the comparison of the ammonia concentrations in the farrowing pens with permanent limited range of motion between the zones of lactating sows and piglets and the impact of the day hour on ammonia concentration in this place. Photoacoustic infrared measuring devices INNOVA were used. The average values of NH<sub>3</sub> concentration ranged from 0.787738 ppm (0.547478 mg/m<sup>3</sup>) to 0.818091 ppm (0.568573 mg/m<sup>3</sup>). The minimum concentration of NH<sub>3</sub> was measured in the second lactating sows zone (0.262535 ppm, 0.182462 mg/m<sup>3</sup>) and the maximum concentration was measured in the piglets zone (1.61803 ppm, 1.124531 mg/m<sup>3</sup>). Values measured met the requirements of the Decree No. 230/1998 of the Ministry of Agriculture and Rural Development of the Slovak Republic which allows the maximum concentration of NH<sub>3</sub> in the pig building 20 ppm (13.9 mg/m<sup>3</sup>). There were no differences between the concentrations of the greenhouse gases (GHGes) in the zones of lactating sows and piglets.

Abstract Purpose Malunions are a common complication after tibial plateau fractures (TPF), leading to stiffness, pseudo-instability and posttraumatic osteoarthritis. The purpose of this study was to analyse the clinical outcome after intraarticular osteotomy of malunited TPF and to perform a failure analysis. Methods Between 2013 and 2018, 23 patients (11 males, 12 females; 43.8 ± 12.8 years) with intraarticular osteotomy after malunited TPF were included in the retrospective study. Clinical examination and postoperative scores were collected with a minimum follow-up of 24 months. Malunion was measured on pre- and postoperative CT scans and localized according to the 10-segment classification while the leg axis in the frontal plane was measured pre- and postoperatively on long leg standing radiographs. Results Excellent and good clinical outcome was achieved in 73.9% (n = 17) of the cases and patient related outcome improved significantly (Tegner 3.3 ± 1.6–5 ± 1.8, p < 0.001; clinical Rasmussen 14.6 ± 3.8–24.9 ± 4.4, p < 0.001). Radiological parameters also improved as an intraarticular step-off was reduced from 9 ± 3.8 to 0.6 ± 0.8 mm (p < 0.001) and a lower limb malalignment from 7.2 ± 4.8° to 1.5 ± 1.9° (p = 0.003). Failure analysis showed that an impaired clinical result correlated with a postoperative extension (n = 3, p < 0.001) and flexion deficit (n = 4, p = 0.035). Conclusion Intraarticular osteotomy of malunited TPF lead to good clinical results with significant clinical and radiological improvement in most cases while an impaired patient outcome correlated with a limited range of motion. This study is the first failure analysis of intraarticular osteotomy after malunited TPF published up to now.

Compensatory Motion

The prostheses used by the majority of persons with hand/arm amputations today have a very limited range of motion. Transradial (below the elbow) amputees lose the three degrees of freedom provided by the wrist and forearm. Some myoeletric prostheses currently allow for forearm pronation and supination (rotation about an axis parallel to the forearm) and the operation of a powered prosthetic hand. Older body-powered prostheses, incorporating hooks and other cable driven terminal devices, have even fewer degrees of freedom. In order to perform activities of daily living (ADL), a person with amputation(s) must use a greater than normal range of movement from other body joints to compensate for the loss of movement caused by the amputation. By studying the compensatory motion of prosthetic users we can understand the mechanics of how they adapt to the loss of range of motion in a given limb for select tasks. The purpose of this study is to create a biomechanical model that can predict the compensatory motion using given subject data. The simulation can then be used to select the best prosthesis for a given user, or to design prostheses that are more effective at selected tasks, once enough data has been analyzed. Joint locations necessary to accomplish the task with a given configuration are calculated by the simulation for a set of prostheses and tasks. The simulation contains a set of prosthetic configurations that are represented by parameters that consist of the degrees of freedom provided by the selected prosthesis. The simulation also contains a set of task information that includes joint constraints, and trajectories which the hand or prosthesis follows to perform the task. The simulation allows for movement in the wrist and forearm, which is dependent on the prosthetic configuration, elbow flexion, three degrees of rotation at the shoulder joint, movement of the shoulder joint about the sternoclavicular joint, and translation and rotation of the torso. All joints have definable restrictions determined by the prosthesis, and task.

Bilateral Posterior Shoulder Dislocation

AbstractIntroduction. Bilateral posterior dislocation of the shoulder is a rare injury, accounted for about 2–5% of all shoulder dislocations. Main courses are electrical shock, epilepsy or extreme trauma with uncontrolled muscle forces. We report about a case of bilateral posterior shoulder dislocation without additional fractures but with a concomitant acromioclavicular joint dislocation. Case presentation. A 46-year-old Caucasian motorcyclist presented to our facility after a fall on slippery ground. He claimed pain in both shoulders with limited range of motion. The initial X-rays were inconclusive, clinical examination showed typical findings of a Rockwood injury with an additional limited external rotation so that a posterior shoulder dislocation was suspected. The CT scan confirmed the clinical suspicion. A closed reduction was performed followed by immobilization in a shoulder abduction pillow for 4 weeks and continuous physiotherapy. Upon follow up normal function with full range of motion was observed. Conclusion. A bilateral posterior shoulder dislocation can be caused by trauma and results in a limited range of motion with often additional injuries. Due to the unusually presentation the risk of missing the injury is increased. Therefore it is most important to consider this rare diagnosis and in case of clinical suspicion perform a careful algorithm of diagnostic.

Abstract Purpose Given that tibial plateau fractures (TPF) are rare, they may pose a challenge to the treating surgeon due to their variety of complex fracture patterns. Numerous studies have identified potential fracture-specific, surgery-related, and patient-related risk factors for impaired patient outcomes. However, reports on the influence of bone metabolism on functional outcomes are missing. Methods In a retrospective multicenter cohort study, 122 TPF of 121 patients were analyzed with respect to radiological and clinical outcomes (Rasmussen) with a mean follow-up of 35.7 ± 24.9 months. The risk factor assessment included bone metabolism-affecting comorbidities and medication. Results The findings showed that 95.9% of the patients reported a good-to-excellent clinical outcome, and 97.4% reported a good-to-excellent radiological outcome. Logistic regression revealed that potentially impaired bone metabolism (IBM) was an independent risk factor for the clinical (p = 0.016) but not the radiological outcome (Table 4). Patients with 41-type B fractures and a potential IBM had a seven times higher risk to present a fair-to-poor clinical outcome [OR 7.45, 95 CI (4.30, 12.92)]. The most common objective impairment was a limited range of motion in 16.4% of the patients, especially in 41-type C fractures (p = 0.06). The individual failure analysis additionally identified surgery-related options for improvement. Conclusion This study demonstrated that potential IBM was an independent risk factor for a poor-to-fair clinical outcome.
