1/46. Conservative management of C5-C6 fracture-luxation in the elderly. Case report.

    The case of a 86-year-old female victim of cervical trauma with C5-C6 fracture-luxation and bilateral locked facets is hereinafter described. The case was reputed representative of the complexity in deciding between conservative and surgical treatment in spine surgery. Conservative management would have been dictated by the additional risks linked to the age of the patient, whereas the surgical treatment would have been favored by the easy access to the anterior cervical spine for reduction and fixation. On the way to plan the definitive treatment, the patient died by pulmonary embolism. The controversial aspects and the indication to anticoagulant therapy in spinal surgery, frequently faced in the treatment of spine trauma in patients of this age group, are discussed in this case report.

2/46. Transarticular fixation with the capacity for motion in fracture dislocations of the elbow.

    Post-traumatic stiffness of the elbow joint is a frequent result of immobilisation leading to severe disability in the use of the upper extremity. Recognition of the tendency to stiffness leads to the assumption that the strong self-healing forces of the capsule and ligament apparatus converts the initial instability of the joint after ligament disrupture, into a high-grade undirected stability following immobilisation. Directed stability as it is produced by the natural ligament apparatus of the joint on the other hand produces a guided movement of the joint in one direction. These theoretical considerations lead to the idea that the self-healing forces of the ligament apparatus under continuous guided movement of the joint will result in a stable and movable joint to allow healing of the compromised soft tissue envelope and moreover to maintain free soft tissue access without compromising the stability. For this a unilateral fixator with motion capacity was developed. The joint bridging application approaches the humerus and ulna from the lateral side. The proximal pin group is inserted into the proximal region of the humerus respecting the radial nerve. The distal pin group is implanted from the dorsal side into the middle third of the ulna. The fixator has a hinge joint. The design of the fixator clamps, bars and the hinge joint allows simple alignment with the rotational axis of the elbow. Pro- and supination of the forearm is unhindered. Flexion and extension can be permitted according to the soft tissue situation.

3/46. brachial artery injury in closed posterior elbow dislocation case report.

    The authors describe a case with a closed posterior elbow dislocation associated with a distal radial fracture and complete transsection of the brachial artery. The patient had a pulseless distal upper extremity and immediate gross swelling of the elbow and forearm. As closed reduction was not possible, open reduction had to be performed through an anteromedial approach to the elbow. End-to-end suture of the brachial artery was successful. After fasciotomy and internal fixation of the distal radial fracture, the elbow was stabilized with an external fixator spanning the elbow joint. After two years, despite good function of the elbow, restoration of the hand function is not optimal owing to persistent motor deficit of the ulnar nerve.

4/46. Orthopaedic measurements with computed radiography. Methodological development, accuracy, and radiation dose with special reference to the weight-bearing lower extremity and the dislocating patella.

    The overall aim of this study was to develop and evaluate a measurement system for computed radiography (CR) and Picture Archiving and communication Systems (PACS), permitting measurements of long distances and angles in and between related images. The developed measurement system, which was based on the QUESTOR Precision radiography (QPR) system, was applied to the weight-bearing knee with special reference to the dislocating patella. The QPR system modified for CR fulfilled the criteria for measuring the weight-bearing knee. The special measuring assistance tools that were developed were important for the implementation of CR and PACS, particularly in workstations programmed for musculoskeletal radiology. The energy imparted to the patient was reduced by 98% at the lowest exposure of the CR-system, compared with our conventional analogue method, without loss of diagnostic accuracy. The CR technique creates a possibility, to an extent not previously feasible, to differentiate the exposure parametres (and thus minimise the radiation dose to the patient) by carefully considering the purpose of the examination. A radiographic method for measuring the rotation of the femur and the tibia, the Q-angle, and the patellar translation was developed and applied to healthy volunteers. The introduced patellar variables have yielded new insights into the complex sequence of motions between the femur, tibia, and patella. The patients with a dislocating patella were subdivided into one "clean" group of spontaneous dislocations and one group with various traumas in the history, which thus resulted in two groups with distinct radiographic differences. The Q-angle was decreased in knees that had suffered dislocations, and the traditional surgical treatment with a further reduction of the Q-angle must be challenged. The use of clinical measurements of the Q-angle was not an optimal way to evaluate the mechanical alignment in the patellofemoral joint under physiological conditions. In this study, we have proved that the developed method for CR and PACS is a useful technique for measurements in and between related images, and is superior to the conventional analogue technique.

5/46. Elongation of the aorta and multiple cardiovascular abnormalities associated with larsen syndrome.

    Larsen syndrome is a genetically heterogeneous group of disorders characterized by multiple joint dislocations and a characteristic face. We describe a girl with the typical features of Larsen syndrome. She also had associated multiple cardiovascular anomalies. The anomalies included elongation of the aorta, bicuspid aortic valve, subaortic stenosis, mitral valve prolapse with mitral regurgitation, atrial septal defect of the secundum type, and a patent ductus arteriosus.

6/46. Isolated dislocation of the thumb carpometacarpal joint in a child.

    Isolated thumb carpometacarpal joint dislocation in the pediatric age group is very rare. We report on a child who suffered this injury and was treated conservatively with excellent outcome.

7/46. Dislocation of the knee with lateral dislocation of the patella. A report of four cases.

    In a group of 25 patients with traumatic dislocation of the knee, four, all of whom had similar ligament and medial soft-tissue injuries, also had associated lateral patellar dislocation. In all four reconstruction was delayed because of their other serious injuries. Having encountered the combination of knee dislocation and lateral patellar dislocation in 16% of our patients, we believe that it may be less rare than is commonly believed. We think that it is important to maintain a high index of suspicion of possible patellar dislocation when medial structures have been severely damaged. Early recognition and immobilisation in extension can prevent fixed lateral dislocation of the patella.

8/46. A comparison of open and closed treatment of condylar fractures: a change in philosophy.

    A comparison between two samples of patients with condylar fractures is reported: the first treated non-surgically and the second with open reduction and rigid internal fixation. The functional results for both groups were similar. However, open reduction gave better occlusal results, anatomic restoration and faster recovery rates than non-surgical techniques.

9/46. Delayed decompression of chronic C1C2 subluxation in a pediatric patient with tetraplegia--is recovery possible?

    A 2 year-old Malay girl was admitted to our institution with a chesty cough and breathlessness but later found to have a chronic C1/C2 subluxation for one and half year with tetraplegia. Her cervical cord was decompressed and occipito-cervical fusion performed. Her neurological status improved significantly post-operatively and is able to care for her personal hygiene. The authors believe that the ability of the cervical cord to recover in the paediatric age group is remarkable that surgical option should be considered even when all seen lost. We believe that this is the first report in the literature to support this potential.

10/46. Failure of active extension after traumatic cubitus varus. A case report.

    In children cubitus varus is common after malunion of a supracondylar fracture of the humerus. Later problems such as tardy ulnar nerve palsy, snapping of the lateral triceps tendon or ulnar nerve and posterolateral rotatory instability are well documented. We present a case of anteromedial dislocation of the entire triceps tendon with loss of extensor power and describe the method of treatment.
