Physical Exam and Evaluation of the Unstable Shoulder.

BACKGROUND: The clinical evaluation of the patient with shoulder instability can be challenging. The pathological spectrum ranges from the straightforward "recurrent anterior dislocation" patient to the overhead athlete with a painful shoulder but not clear instability episodes. Advances in shoulder arthroscopy and imaging have helped in understanding the anatomy and physiopathology of the symptoms. The aim of this general article is to summarize the main examination manoeuvres that could be included in an overall approach to a patient with a suspicion of instability. MATERIAL AND METHODS: In order to achieve the above-mentioned objective, a thorough review of the literature has been performed. Data regarding sensibility and specificity of each test have been included as well as a detailed description of the indications to perform them. Also, the most frequent and recent variations of these diagnostic tests are included. RESULTS: Laxity and instability should be considered separately. For anterior instability, a combination of apprehension, relocation and release tests provide great specificity. On the other hand, multidirectional or posterior instability can be difficult to diagnose especially when the main complain is pain. CONCLUSION: A detailed interview and clinical examination of the patient are mandatory in order to identify a shoulder instability problem. Range of motion of both shoulders, clicking of catching sensations as well as pain, should be considered together with dislocation and subluxation episodes. Specific instability and hyperlaxity tests should be also performed to obtain an accurate diagnosis.

Propofol extravasation: a rare cause of compartment syndrome.

We detail a rare cause of forearm compartment syndrome that occurred in an 18-year-old patient who presented with a Glasgow Coma Scale of 13/15 after a mixed drug overdose and subsequently required intubation. She suffered extravasation of her propofol infusion, which resulted in intrinsic compression within her forearm muscle compartments. Fortunately, the diagnosis of compartment syndrome was made swiftly and the patient was taken to theatre within 3 h where she underwent an emergency forearm fasciotomy. She made an uneventful recovery and at follow-up her wounds had healed well with no associated morbidity or loss of function. The learning points of this study highlight the importance of thoroughly understanding the signs and symptoms of compartment syndrome while maintaining a high index of suspicion. In addition to a thorough history and examination, consideration of the potential underlying causes allows for a swifter diagnosis and a quicker transition to theatre.

Management of acute anterior shoulder dislocation.

Shoulder dislocation is the most common large joint dislocation in the body. Recent advances in radiological imaging and shoulder surgery have shown the potential dangers of traditional reduction techniques such as the Kocher's and the Hippocratic methods, which are still advocated by many textbooks. Many non-specialists continue to use these techniques, unaware of their potential risks. This article reviews the clinical and radiographic presentation of dislocation; some common reduction techniques; their risks and success rate; analgesia methods to facilitate the reduction; and postreduction management. Many textbooks advocate methods that have been superceded by safer alternatives. Trainees should learn better and safer relocation methods backed up by the current evidence available.

Conservative management versus open reduction and internal fixation for mid-shaft clavicle fractures in adults--the Clavicle Trial: study protocol for a multicentre randomized controlled trial.

BACKGROUND: Clavicle fractures account for around 4% of all fractures and up to 44% of fractures of the shoulder girdle. Fractures of the middle third (or mid-shaft) account for approximately 80% of all clavicle fractures. Management of this group of fractures is often challenging and the outcome can be unsatisfactory. In particular it is not clear whether surgery produces better outcomes than non-surgical management. Currently there is much variation in the use of surgery and a lack of good quality evidence to inform our decision. METHODS/DESIGN: We aim to undertake a multicentre randomised controlled trial evaluating the effectiveness and safety of conservative management versus open reduction and internal fixation for displaced mid-shaft clavicle fractures in adults. Surgical treatment will be performed using the Acumed clavicle fixation system. Conservative management will consist of immobilisation in a sling at the side in internal rotation for 6 weeks or until clinical or radiological union. We aim to recruit 300 patients. These patients will be followed-up for at least 9 months. The primary endpoint will be the rate of non-union at 3 months following treatment. Secondary endpoints will be limb function measured using the Constant-Murley Score and the Disabilities of the Arm, Shoulder and Hand (DASH) Score at 3 and 9 months post-operatively. DISCUSSION: This article presents the protocol for a multicentre randomised controlled trial. It gives extensive details of, and the basis for, the chosen methods, and describes the key measures taken to avoid bias and to ensure validity. TRIAL REGISTRATION: United Kingdom Clinical Research Network ID: 8665. The date of registration of the trial is 07/09/2006. The date the first patient was recruited is 18/12/2007.

Management of osteoarthritis of the glenohumeral joint.

The National Institute for Health and Clinical Excellence will this year publish general guidelines for the management of osteoarthritis. The surgical management of shoulder arthritis has been an area of marked activity in the last decade. This article reviews current trends in the management of glenohumeral osteoarthritis.

Metastatic adenocarcinoma of the colon presenting as a monarthritis of the hip in a young patient.

BACKGROUND: Malignant arthritis is a rare manifestation of metastatic disease. We describe the case of a previously well 28 year old man in whom hip pain was the presenting symptom of disease. We describe the case and discuss the aetiology of colorectal cancer in young patients. We then review the literature and discuss the investigation and management of malignant joint arthritis. CASE PRESENTATION: We present the case of a 28 year old man who presented to the emergency department with an acute monoarthritis of the hip. He had an unremarkable past medical history and was systemically well. A diagnosis of malignant joint effusion was reached after a heightened index of clinical suspicion, magnetic resonance imaging and cytological evaluation of the synovial fluid. Computed tomography and bone scan confirmed widespread metastatic disease from a primary colonic adenocarcinoma. The patient tolerated three cycles of oxaliplatin and capecitabine but died 4 months after presentation. CONCLUSION: The metastatic spread of cancer to the joint and the synovium is one of the rarest manifestations of malignant disease and has not been previously reported as the presenting symptom of disease. The diagnosis is a difficult one to reach and is associated with a poor prognosis. This case illustrates the importance of thorough investigation in reaching this diagnosis and entertaining the possibility in individuals who do not respond to conventional management of acute monoarthritis, even in young patients and individuals who do not display any other symptoms of disease.

Shoulder pain in sports.

Shoulder pain in athletic individuals is common, particularly in those sports that are upper limb dominant. It is important to make an accurate diagnosis so that appropriate treatment can be directed at the cause.
