Asymptomatic anterior shoulder dislocation of 24-year duration

A 73-year-old woman presented with a very long-standing anterior dislocation of her right shoulder. She had no pain, mild impairment of active shoulder motion and clinical features suggesting no tear of the rotator cuff. CT 3D reconstructions showed a newly formed glenoid cavity below the coracoid process. This case indicates that an anterior shoulder dislocation lasting even decades may be compatible with an almost normal shoulder function

Open reduction and internal fixation combined with hinged elbow fixator in capitellum and trochlea fractures: a retrospective study of 15 patients followed for 29 months

Background and purpose The current surgical treatment for displaced fracture of the capitellum and trochlea is open reduction and internal fixation (ORIF), but the results are often unsatisfactory, particularly with complex fractures. Furthermore, the surgical approach, the kind of osteosynthesis, and postoperative management are controversial. We evaluated the results of internal fixation combined with hinged external fixation. Methods We analyzed 15 patients with a mean age of 47 (18-65) years. Based on the Bryan-Morrey-McKee classification, the fractures were identified as type I in 6 cases and type IV in 9. Active and passive motion was started and activities of daily living were permitted on the second postoperative day. The mean follow-up time was 29 (12-49) months. Results In 13 cases, functional range of motion was obtained within 6 weeks of surgery. At final follow-up, 14 patients had a stable, pain-free elbow with a mean active range of motion of 13° to 140°. The average score on the Mayo elbow performance score was 98. Interpretation The use of the hinged fixator allows early motion of the elbow while preserving joint stability. It may have additional value in complex articular fractures when stable internal fixation cannot be obtained with ORIF, and in the presence of severe ligamentous injuries

Analysis of LGV usage for the improvement of a customized production

The paper describes an approach for analyzing the use of a Laser-Guided Vehicle (LGV) in the context of the small and medium-sized enterprise. The use of LGVs is an efficient solution to provide more flexibility in the context of Just-In-Time production; however, the investment cost can limit this application. A methodology has been proposed in this work to analyze the technical feasibility of using an LGV in the manufacturing industry of customized products. The test case focuses on the study of a laser-guided system to optimize the handling of molds for customized production. In this scenario, an LGV is proposed to substitute manual carts used for moving molds from the warehouse to the injection machines. The traditional path included an intermediate station for pre-heating the molds in hot-air ovens. The proposed solution includes the study of an induction heating system on the LGV to optimize time and energy consumption

Coccydynia

Coccydynia is a term that refers to pain in the region of the coccyx. Most cases are associated with abnormal mobility of the coccyx which may trigger a chronic inflammatory process leading to degeneration of this structure. In some patients this instability may be detected on dynamic radiographs. Nonsurgical management remains the gold standard treatment for coccydynia, consisting of decreased sitting, seat cushioning, coccygeal massage, stretching, manipulation, local injection of steroids or anesthetics, and postural adjustments. Those patients who fail these conservative modalities may potentially benefit from coccygectomy. However, surgical intervention is typically reserved for patients with evidence of advanced coccygeal instability (e.g., subluxation or hypermobility) or spicule formation, as this population appears to exhibit the greatest improvement postoperatively

Difficulty in diagnosing the pathological nature of an acute fracture of the clavicle: a case report

Fractures of the clavicle comprise between 5% to10% of all fractures. Medial clavicular fractures are uncommon and are normally caused by high-energy trauma. A low impact mechanism of injury should raise suspicion of a pathological fracture, but this case report highlights the difficulty in diagnosing the pathological nature of an acute fracture of the clavicle. We describe a patient who presented with a medial clavicular fracture after a simple fall but the fracture was diagnosed as pathological in retrospect four months after the initial presentation. We would also like to emphasise that the medial clavicle is the most frequent site of pathological fractures of the clavicle, and the possibility of an underlying pathological condition should be considered whenever a patient with a medial clavicular fracture is encountered

Treatment of chronic anterior shoulder dislocation by open reduction and simultaneous Bankart lesion repair

<p>Abstract</p> <p>Background</p> <p>Untreated chronic shoulder dislocation eventually leads to functional disability and pain. Open reduction with different fixation methods have been introduced for most chronic shoulder dislocation. We hypothesized that open reduction and simultaneous Bankart lesion repair in chronic anterior shoulder dislocation obviates the need for joint fixation and leads to better results than previously reported methods.</p> <p>Methods</p> <p>Eight patients with chronic anterior dislocation of shoulder underwent open reduction and capsulolabral complex repair after an average delay of 10 weeks from injury. Early motion was allowed the day after surgery in the safe position and the clinical and radiographic results were analyzed at an average follow-up of one year.</p> <p>Results</p> <p>The average Rowe and Zarin's score was 86 points. Four out of eight shoulders were graded as excellent, three as good and one as fair (Rowe and Zarins system). All patients were able to perform their daily activities and they had either mild or no pain. Anterior active forward flexion loss averaged 18 degrees, external active rotation loss averaged 17.5 degrees and internal active rotation loss averaged 3 vertebral body levels. Mild degenerative joint changes were noted in one patient.</p> <p>Conclusion</p> <p>The results show that the overall prognosis for this method of operation is more favorable than the previously reported methods and we recommend concomitant open reduction and capsulolabral complex repair for the treatment of old anterior shoulder dislocation.</p> <p>Level of Evidence</p> <p>Therapeutic study, Level IV (case series [no, or historical, control group])</p

The accuracy of MRI in the detection of Lumbar Disc Containment

<p>Abstract</p> <p>Background</p> <p>MRI has proven to be an extremely valuable tool in the assessment of normal and pathological spinal anatomy. Accordingly, it is commonly used to assess containment of discal material by the outer fibers of the anulus fibrosus and posterior longitudinal ligaments. Determination of such containment is important to determine candidacy for intradiscal techniques and has prognostic significance. The accuracy of MRI in detecting containment has been insufficiently documented.</p> <p>Methods</p> <p>The MRI's of fifty consecutive patients undergoing open lumbar microdiscectomy were prospectively evaluated for disc containment by a neuroradiologist and senior spinal surgeon using criteria available in the literature and the classification of Macnab/McCulloch. An independent surgeon then performed the surgery and documented the actual containment status using the same methods. Statistical evaluation of accuracy was undertaken.</p> <p>Results</p> <p>MRI was found to be 72% sensitive, 68% specific, and 70% accurate in detecting containment status of lumbar herniated discs.</p> <p>Conclusion</p> <p>MRI may be inaccurate in assessing containment status of lumbar disc herniations in 30% of cases. Given the importance of containment for patient selection for indirect discectomy techniques and intradiscal therapies, coupled with prognostic significance; other methods to assess containment should be employed to assess containment when such alternative interventions are being considered.</p
