Background: The aim of this study was to assess demographics, clinical outcomes, and complications of classic floating elbow in adults. Methods: Six patients with ipsilateral diaphyseal fractures of the humerus, radius, and ulna were reviewed retrospectively. All patients were treated operatively and available for follow-up at a minimum of 1 year after surgery. The average age of the patients was 45.2 years (22-64 years) and the average follow-up period was 37.0 months (14-103 months). They were evaluated with postoperative outcome measures, including a visual analog scale (VAS) for pain, Mayo elbow performance score (MEPS), and American Shoulder and Elbow Surgeons (ASES) shoulder score. Residual complications were also evaluated. Results: Five patients (83.3%) had open fracture, and 4 patients (66.7%) presented with associated nerve injury. All fractures were united within postoperative 4 months, except 1 delayed union. The average VAS pain score, MEPS, and ASES shoulder score at the final follow-up examination was 2.5, 79.8, and 67.5 respectively. Three patients including 2 cases of joint stiffness with incomplete recovery from nerve injury and 1 case of complex regional pain syndrome had poor clinical outcome. Conclusions: Although the classic floating elbow is rare, these injuries potentially have associated problems such as open fracture or nerve injury. The presence of residual neurological symptoms predispose to poorer clinical outcomes.

A triple disruption of the SSSC, an extremely rare injury, has been reported by only a few authors. We present a patient who had sustained a triple disruption of the SSSC: coracoid and scapular spine fractures, and an acromioclavicular joint separation. Treatment consisted of an anatomical restoration of the SSSC, with maintenance of the acromiohumeral and coracohumeral distances; this was achieved by open reduction and internal fixation of the fractures and of the separation. Six months after surgery, the injured shoulder was asymptomatic, with full range of motion. Five years after surgery, at the final follow-up, the function of the SSSC had been restored to the patient's complete satisfaction.

A series of hydraulic and cavitation tests are performed in water environment in order to verify the hydraulic and cavitation performance of three types of LOX pumps. All the performances of the pumps are found to be satisfied with each design requirement. In the hydraulic tests, the head and efficiency are increased as the gap between floating ring seals and the impeller shoulder is decreased. In the cavitation tests, some pumps show decrease in the cavitation performance as the flowrate of the pump is decreased.

Purpose: While all midshaft clavicle fractures have traditionally been treated with conservative measures, recent operative treatment of displaced, communited midshaft clavicle fractures has become more common. Though a recent increase in operative treatment for midshaft clavicle fractures, we have done the operative methods in limited cases. The aim of this study is to present indications, operative techniques and outcomes of the experienced cases that have applied to this limited group over the previous 10 years. Methods: This study consists of a retrospective review of radiological and clinical data from January of 2005 to July of 2015. Operative criteria for midshaft clavicle fractures having considerable risk of bone healing process were 4 groups - a floating shoulder, an open fracture, an associated neurovascular injury, and a nonunion case after previous treatment. Results: The study consisted of 18 patients who had operative treatment for midshaft clavicle fractures in adults. The most common surgical indication was a floating shoulder (10 cases, 55.6%), followed by nonunion (5 cases, 27.8%), an associated neurovascular injury (4 cases, 22.2%), and open fracture (3 cases, 16.7%). All cases were treated by open reduction and internal fixation in anterosuperior position with reconstruction plate or locking compression plate. Bone union was achieved in all cases except 1 case which was done bone resection due to infected nonunion. Mean bone union period was 19.5 weeks. There were no postoperative complications, but still sequelae in 4 cases of brachial plexus injury. Conclusion: We have conducted an open reduction and internal fixation by anterosuperior position for midshaft clavicle fractures in very limited surgical indications for last 10 years. Our treatment strategy for midshaft clavicle fractures showed favorable radiological results and low postoperative complications.

Concomitant ipsilateral fractures of the humerus, radius and ulna are uncommon combined injury and are also called "floating elbow". It was found that this injury was usually a result of rather severe trauma and frequently associated injuries to other organ systems. It is controversial in the treatment of the "floating elbow", but the current treatment recommendations are open reduction and internal fixation of both the humerus and the forearm fracture with early initiation of range of motion exercises. The authors reviewed thirteen cases of ipsilateral fractures of the humerus, radius and ulna treated in our clinic from January 1992 to March 1997, and average follow-up period was over 18 months(range, 12 to 36 months). The results obtained were as follows; 1. The most common cause of injury was traffic accident and most common location of fractures was mid-third in both humerus and forearm. 2. The shape of fractures was transverse or comminuted in most cases. 3. The good clinical results were obtained by open reduction and internal fixation of both the humerus and the forearm fracture with early initiation of range of motion exercises. 4. The recovery was affected by the severity of the initial trauma and method of the treatment. 5. According to the Lange and Foster method, the functional result was good in 8 cases, fair in 4 cases and poor in 1 cases.
