Lumbosacral dislocation: A review of the literature and current aspects of management

Lumbosacral fracture dislocation is a very rare lesion and was first described by Watson-Jones in 1940. Two anatomical classifications are described in the literature, all other reports are case presentations.This fracture type is characterised by an antero- or retrolisthesis or a lateral translation of the 5th lumbar vertebra in relation to the sacrum. Biomechanics are discussed controversially. Most patients suffer from a high energy trauma with concomitant severe injuries. There is a high rate of additional neurological deficits. Fractures of the transverse process are thought to be sentinel fractures. MRI and CT scans are essential to detect the whole extent of the lesion. Circumferential fusion is recommended by several authors to regain stability at the lumbosacral junction.     

Posterior sternoclavicular epiphyseal fracture-dislocation: Case report and review of literature

Posteriorly displaced physeal fractures of the medial clavicle are relatively rare injuries in the growing skeleton and are often confused with the posterior dislocations of the sternoclavicular joint (SCJ). Frequently, these initially undiagnosed due to variable clinical presentation and inadequate visualisation of the joint on plain radiographs. This failure of diagnosis or delayed treatment may lead to serious complications though secondary injuries of mediastinal structures.We present a case report of a 16-year-old male with posterior sternoclavicular epiphyseal fracture-dislocation without vasculonervous injury that occurred in basketball training. The correct diagnosis required multiple modalities over two emergency department visits. Computed tomography with intravenous contrast was the imaging modality of choice for diagnosis. Treatment consisted of attempts at closed reduction, which was not successful. Open reduction was performed with relocation of the clavicle into the periosteal sleeve followed by strong suture material. We have reviewed the literature to provide an insight with regards to correct diagnosis and management of this injury.     

Elbow fracture-dislocation combined with Galeazzi fracture in adult: A case report and literature review

INTRODUCTIONGaleazzi fracture associated with ipsilateral posterior elbow dislocation and radial head fracture is a rare pattern of injury. Few reports exist that describes this injury pattern and its treatment. We describe a case report of simultaneous occurrence of Galeazzi fracture and ipsilateral dislocation of elbow.PRESENTATION OF CASEA 58 year-old female presented with Galeazzi fracture and posterior elbow dislocation associated with radial head fracture of left upper extremity. This was managed with closed reduction of the elbow, open reduction and internal fixation of the radial shaft fracture and K-wire stabilisation of the unstable distal radioulnar joint. Prophylactic fasciotomy was performed. At 10 months follow-up, the outcome was favourable with the American shoulder and elbow surgeon score of 92 and the disabilities of the arm, shoulder and hand score of 18.DISCUSSIONThe presumed mechanism of the injury was a forceful axial loading of a hyperpronated forearm and extended elbow. Our literature review shows that this pattern of injury occurs as a result of high energy trauma in young individuals, and successful outcome can be achieved by addressing each component of this complex injury individually.CONCLUSIONSimultaneous occurrence of elbow dislocation and Galeazzi fracture seems to be the result of extreme axial force and unique position of upper extremity at the time of impact. Individualised approach to each component of this injury can result in favourable outcome.     

True congenital dislocation of shoulder: A case report and review of the literature

The dislocation of a shoulder joint in infancy is extremely rare and is usually the result of traumatic birth injuries, a sequel to brachial plexus injury, or a true congenital dislocation of shoulder. With more advanced obstetric care, the incidence of first two types has drastically decreased. We report a case of true congenital dislocation of shoulder, second of its kind, in a child who was delivered by cesarean section thereby negating any influence of trauma. We report the case because of its rarity, and review the available literature on this topic. We also discuss the management options when encountered with such a rare case scenario.     

Bilateral anterior fracture-dislocation shoulder: a case report with a review of the literature

Although bilateral anterior dislocation of the shoulders are not that much uncommon, but incidences of bilateral anterior fracture-dislocation shoulder are relatively rare with about 16 reported cases in the world literature. We report a rare case of bilateral anterior dislocation of the shoulders with bilateral 3-part fracture of the proximal humerus after first time epileptic attack. The diagnosis of bilateral anterior fracture shoulder dislocation was done on the same day of the epileptic injury, and patient had been operated within 48 h of injury. Patient was treated with open reduction and internal fixation through the delto-pectoral approach for both the sides. For right side, fixation was done with proximal humerus locking plate, and for left side, fixation was done with multiple screws with washers. Primary rotator cuff repair was done on both the sides. We had got excellent result in our case report at 1-year follow-up. The literature on this injury is also reviewed.     

Sternoclavicular joint dislocation and its management: A review of the literature

Dislocations of the sternoclavicular joint(SCJ) occur with relative infrequency and can be classified into anterior and posterior dislocation, with the former being more common. The SCJ is inherently unstable due to its lack of articular contact and therefore relies on stability from surrounding ligamentous structures, such as the costoclavicular, interclavicular and capsular ligaments. The posterior capsule has been shown in several studies to be the most important structure in determining stability irrespective of the direction of injury. Posterior dislocation of the SCJ can be associated with life threatening complications such as neurovascular, tracheal and oesophageal injuries. Due to the high mortality associated with such complications, these injuries need to be recognised acutely and managed promptly. Investigations such as x-ray imaging are poor at delineating anatomy at the level of the mediastinum and therefore CT imaging has become the investigation of choice. Due to its rarity, the current guidance on how to manage acute and chronic dislocations is debatable. This analysis of historical and recent literature aims to determine guidance on current thinking regarding SCJ instability, including the use of the Stanmore triangle. The described methods of reduction for both anterior and posterior dislocations and the various surgical reconstructive techniques are also discussed.     

Posterior shoulder instability following anatomic total shoulder arthroplasty: A case report and review of management

We report a case of posterior shoulder instability following anatomic total shoulder arthroplasty (TSA). In addition, we present guidelines to aid in the management of posterior instability after TSA. A 50-year-old male underwent anatomic TSA for glenohumeral osteoarthritis. Postoperatively, the patient developed posterior instability secondary to glenoid retroversion. He did not improve despite conservative treatment. He underwent an arthroscopic posterior bone block procedure, 4-month after his index arthroplasty. At 14-month follow-up, the patient had regained near full motion and strength, and radiographs demonstrated osseous integration with no evidence of component loosening. Posterior instability following TSA is a relatively rare complication and challenging to manage. The posterior, arthroscopic iliac crest bone block grafting procedure represents a treatment option for posterior instability in the setting of a stable glenoid prosthesis following TSA.     

Simultaneous bilateral anterior shoulder dislocation: report of two cases and review of the literature

Bilateral shoulder dislocations are rare and almost always occur in the posterior direction. Simultaneous bilateral anterior shoulder dislocation is even rarer and only a few cases are stated in the literature. The most interesting part of a bilateral shoulder dislocation is about its injury mechanism as a synchronous and simultaneous force is needed to result in it. In cases of epilepsy or electrocution, the mechanism is different and the forceful contractions of the selective group of muscles result in the dislocation. This article reports two cases of bilateral simultaneous anterior shoulder joint dislocation that occurred after a road side accident and after an episode of convulsion in an epileptic patient. The dislocations were diagnosed early and reduced immediately with a proper postreduction rehabilitation. During their follow-up, both patients had satisfactory functional outcome. This article emphasizes on the importance of shoulder examination in road side accident victims and epileptic patients. All orthopedic surgeons and emergency physicians should be aware of such unusual possibilities to have an early diagnosis and treatment.An early reduction and appropriate rehabilitation can provide satisfactory functional outcome. This article also briefly discusses the injury mechanisms, diagnoses and treatments of bilateral shoulder dislocation as reported in the literature.     

Superior sternoclavicular joint dislocation presented with shoulder motion limitation: A case report and literature review

Introduction and importanceSternoclavicular joint dislocation accounts for 1 percent of the human joint dislocations. Sternoclavicular joint dislocation most commonly occurs in anterior or posterior dislocation. To the best of the authors knowledge, only six cases of superior sternoclavicular joint dislocation are reported in the literature. The injury is commonly missed.Case presentationWe present a 28-year-old athlete with upper chest pain and right shoulder range of motion limitation. On imaging, it was revealed that he had a superior sternoclavicular dislocation. He was managed with arm sling, analgesics and physiotherapy. After 3 months, he was asymptomatic and returned to his sport activity successfully.Clinical discussionWe searched the published related studies and summarized the signs and symptoms of patients presented with sternoclavicular dislocation. Chest pain is one of the most common symptom while sternoclavicular tenderness and restriction of shoulder movement are among the most common signs of sternoclavicular dislocations. Conservative, close reduction, and open reduction and internal fixation with fiber wire have been applied for cases with superior sternoclavicular dislocation with acceptable results.ConclusionA high index of suspicion is needed in order not to miss sternoclavicular dislocation. In cases with no evidence of mediastinal structure compression it may be managed conservatively successfully. However, some degree of cosmetic deformity may remain at the sternoclavicular joint in those treated with conservative therapy.     

Brucella infection following total joint arthroplasty: A systematic review of the literature

Introduction

The aim of this systematic review was to analyze the results of published treatment options in Brucella infection following total joint arthroplasty (TJA).

Posterior fracture-dislocation of the hip: an epidemiologic review.

A retrospective study of 46 posterior fracture-dislocations of the hip showed that reduction of the dislocation within 24 hours was the most important initial treatment. Open reduction and fixation of the fracture could be delayed up to 4 weeks to allow associated injuries to be treated, and this technique was indicated to remove intra-articular bone fragments or for residual instability. Long-term disability resulted in every patient, regardless of the severity of the initial injury or the method of treatment. Half of the patients never returned to work. Of the 46 patients 43 were unrestrained occupants in vehicular accidents. Multiple injury occurred in 75% of the patients.     

Surgical management of U-shaped sacral fractures: a systematic review of current treatment strategies

Purpose  

U-shaped sacral fractures usually result from axial loading of the spine with simultaneous sacral pivoting due to a horizontal fracture which leads to a highly unstable spino-pelvic dissociation. Due to the rarity of these fractures, there is lack of an agreed treatment strategy.     

Posterior fracture-dislocation of the shoulder. A superior subacromial approach for open reduction.

We describe 11 cases of posterior fracture-dislocation of the shoulder that required open reduction and fixation. Difficulties with access through anterior approaches led us to use the superior subacromial approach. This is an extension of the approach often used to expose the rotator cuff; the joint is opened by splitting the supraspinatus tendon 5 mm behind the cuff interval. The glenoid, proximal humerus and any fracture fragments can be seen from above, allowing reduction of the dislocation and osteosynthesis to be performed with minimal risk of damage to the humeral head and its blood supply. The proximity of the axillary nerve limits the exposure of the proximal humeral shaft. The superior subacromial approach is ideal for posterior dislocation with fracture of the articular segment, but is not suitable when there is a fracture of the proximal humeral shaft.
