Conventional Radiograph Is Still Advised in the Diagnostic Work-up of a Shoulder Dislocation; a Letter to the Editor

Dear editor: A shoulder dislocation is a common diagnosis at the emergency department, showing an incidence of 23.9 per 100,000 person-years. In the current diagnostic work-up, a radiograph is often used to confirm the dislocation. As radiographs are associated with radiation exposure, the ultrasound has been proposed as an alternative. Therefore, the study by Entezari et al is of great importance in evaluating the applicability of the ultrasound. However, the authors suggest that the ultrasound can be used as an alternative to the radiograph. In our opinion, an important advantage of the radiograph has not been discussed and we question some decisions that were made in terms of methodology. Therefore, we think that this study has to be seen in the light of these remarks

The occurrence of osteoarthritis at a minimum of ten years after reconstruction of the anterior cruciate ligament

<p>Abstract</p> <p>Objective</p> <p>The objective of this study was to evaluate the incidence of radiographic osteoarthritis in the operated knee in comparison with the contralateral knee ten years after a bone-tendon bone patellar autograft ACL-reconstruction and to evaluate to which level patients regain activity ten years after reconstruction.</p> <p>Methods</p> <p>Fifty-three patients with ACL instability were operated arthroscopically using the central third of the patellar tendon as a bone-tendon-bone autograft. At a minimum of 10 year follow up 28/44 patients matched the inclusion criteria and could be reached for follow-up. Evaluation included a patient satisfaction evaluation using a Visual Analog Scale, physical examination (International Knee Documentation Committee score, Tegner score, Lysholm score, KT-1000 stabilometry) and a radiological evaluation (Kellgren and Fairbanks classification).</p> <p>Results</p> <p>The patients' satisfaction, at a mean of 10,3 year follow-up, measured with a VAS score (0–10) was high with a mean of 8.5 (range 4 to 10). The KT 1000 arthrometer laxity measurements revealed in 55% of the patients an A rating (1–2 mm), in 29% a B rating (3–5 mm) and in 16% a C rating (6–10 mm). According to the Tegner score 54% of the patients were able to perform at the same activity level as pre-operatively. The mean pre-operative Tegner score was 6.8 and the mean post-operative Tegner score was 6.0 at final follow up. The Lysholm score showed satisfactory results with a mean of 91 points (range 56 to 100). According to the Kellgren and Fairbank classifications, there is a significant difference (p < 0.05) in development of OA between the ACL injured and subsequently operated knee in comparison to the contralateral knee.</p> <p>Conclusion</p> <p>The patellar BTB ACL reconstruction does not prevent the occurrence of radiological OA after 10 years but does help the patient to regain the pre-operative level of activity.</p

Reconstructive osteotomy of fibular malunion: review of the literature

The treatment of ankle fractures has a primary goal of restoring the full function of the injured extremity. Malunion of the fibula is the most common and most difficult ankle malunion to reconstruct. The most frequent malunions of the fibula are shortening and malrotation resulting in widening of the ankle mortise and talar instability, which may lead to posttraumatic osteoarthritis. The objective of this article is to review the literature concerning the results of osteotomies for correcting fibular malunions and to formulate recommendations for clinical practice. Based on available literature, corrective osteotomies for fibular malunion have good or excellent results in more than 75% of the patients. Reconstructive fibular osteotomy has been recommended to avoid or postpone sequela of posttraumatic degeneration, an ankle arthrodesis or supramalleolar osteotomy. The development of degenerative changes is not fully predictable; therefore, it is advisable to reconstruct a fibular malunion soon after the diagnosis is made and in presence of a good ankle function. Recommendations were made for future research because of the low level of evidence of available literature on reconstructive osteotomies of fibular malunions

Coronoid fractures and traumatic elbow instability

The coronoid process is key to concentric elbow alignment. Malalignment can contribute to post-traumatic osteoarthritis. The aim of treatment is to keep the joint aligned while the collateral ligaments and fractures heal. The injury pattern is apparent in the shape and size of the coronoid fracture fragments: (1) coronoid tip fractures associated with terrible triad (TT) injuries; (2) anteromedial facet fractures with posteromedial varus rotational type injuries; and (3) large coronoid base fractures with anterior (trans-) or posterior olecranon fracture dislocations. Each injury pattern is associated with specific ligamentous injuries and fracture characteristics useful in planning treatment. The tip fractures associated with TT injuries are repaired with suture fixation or screw fixation in addition to repair or replacement of the radial head fracture and reattachment of the lateral collateral ligament origin. Anteromedial facet fractures are usually repaired with a medial buttress plate. If the elbow is concentrically located on computed tomography and the patient can avoid varus stress for a month, TT and anteromedial facet injuries can be treated nonoperatively. Base fractures are associated with olecranon fractures and can usually be fixed with screws through the posterior plate or with an additional medial plate. If the surgery makes elbow subluxation or dislocation unlikely, and the fracture fixation is secure, elbow motion and stretching can commence within a week when the patient is comfortable.</p

Evidence-based treatment of open ankle fractures

Fractures of the ankle are fairly common injuries. Open ankle fractures are much less common and associated with severe injuries to surrounding tissues. We have performed a systematic review of the literature concerning the clinical results and complication rates in the treatment of open ankle fractures. We conducted a search limited to the following databases: Pubmed/Medline, Cochrane Database of Systematic Reviews, Cochrane Clinical Trial Register and Embase. These were searched from 1968 to April 2010 to identify studies relating to the treatment of open ankle fractures. Fifteen articles concerning 498 patients with treatment of an open ankle fracture were identified. The number of included patients varied from 11 to 64. There were 2 prospective and 13 retrospective studies. All articles were case series and classified as Level IV evidence. In 373 cases, open ankle fractures were treated by immediate internal fixation. In 125 cases, a conservative treatment or delayed/other fixation treatment was followed. Of those patients treated by immediate internal fixation, 81% had satisfactory result. Poor results (15%) were most commonly due to non-anatomic reductions, articular surface damage or deep infection. When conservative treatment was followed, 76% had satisfactory results. The most reported complications after immediate internal fixation were deep infection (8%) and skin necrosis (14%). There is a lack of high quality literature concerning the (operative) treatment of patients with open ankle fractures. Remarkable is that most authors reported satisfactory results after performance of their treatment protocol. Based on the available literature, we formulated guidelines regarding: timing of operative treatment, wound irrigation, the role of internal fixation, wound coverage and closure, the use of antibiotics and additional therapies

Imaging and classification of osteochondritis dissecans of the capitellum: X-ray, magnetic resonance imaging or computed tomography?

Background: Diagnosing capitellar osteochondritis dissecans (OCD) can be difficult, causing delay in treating young athletes. The main aim of this retrospective diagnostic study was to determine which radiological technique is preferred to identify and classify elbow OCD. Methods: We identified young patients who underwent elbow arthroscopy because of symptomatic OCD. We included all patients who had pre-operative radiographs, a computed tomography (CT) scan and magnetic resonance imaging (MRI) available. We assessed whether the osteochondral lesion could be identified using the various imaging modalities. All lesions were classified according to previous classifications for X-ray, CT and MRI, respectively. These results were compared with findings at arthroscopy. Results: Twenty-five patients had pre-operative radiographs as well as CT scans and MRI. In six patients, the lesion was not visible on standard X-ray. In 20 patients, one or two loose bodies were found during surgery, consistent with an unstable lesion. Pre-operatively, this was seen on 11 X-rays, 13 MRIs and 18 CT scans. Conclusions: Capitellar OCD lesions are not always visible on standard X-rays. A CT appears to be the preferred imaging technique to confirm diagnosis of OCD. Loose bodies are often missed, especially on standard X-rays and MRIs
