Pathologic changes associated with shoulder dislocations. Arthroscopic and physical examination findings in first-time, traumatic anterior dislocations.

This prospective observational study was performed on young patients, less than 24 years old, with first-time, traumatic anterior shoulder dislocations. These patients were offered either arthroscopic or nonoperative treatment. Fifty-three patients chose nonoperative treatment. Sixty-three patients elected to have arthroscopic procedures. The average patient age was 19.6 years. There were 59 men and 4 women. All procedures were performed within 10 days of dislocation. All 63 patients had hemarthrosis. Sixty-one of 63 (97%) patients treated surgically had complete detachment of the capsuloligamentous complex from the glenoid rim and neck (Perthes-Bankart lesion), with no gross evidence of intracapsular injury. Of the other two patients, one had an avulsion of the inferior glenohumeral ligament from the neck of the humerus, and one had an interstitial capsular tear adjacent to the intact glenoid labrum. Fifty-seven patients had Hill-Sachs lesions; none were large. There were six superior labral anterior posterior lesions, two with detachment of the biceps tendon. There were no rotator cuff tears. Of the 53 nonoperatively treated patients, 48 (90%) have developed recurrent instability. In this population, the capsulolabral avulsion appeared to be the primary gross pathologic lesion after a first-time dislocation. These findings, associated with the 90% nonoperative recurrence rate, suggest a strong association between recurrent instability and the Perthes-Bankart lesion in this population.

Posterior shoulder dislocations and fracture-dislocations.

Posterior shoulder dislocations and fracture-dislocations are uncommon injuries that most often occur during seizures or as a result of high-energy trauma. Despite advances in imaging, they are frequently diagnosed late. Detection is facilitated by heightened clinical suspicion of the injury in high-risk individuals together with appropriate radiographic investigation. A wide variety of operative techniques, ranging from simple closed reduction to soft-tissue and bone stabilization procedures to prosthetic arthroplasty, are available to treat these injuries. Selection of the most appropriate treatment option is complex and multifactorial. Because of the rarity of these injuries, evidence-based treatment protocols are difficult to devise. Good functional outcomes are associated with early detection and treatment of isolated posterior dislocations that are associated with a small osseous defect and are stable following closed reduction. Poor prognostic factors include late diagnosis, a large anterior defect in the humeral head, deformity or arthrosis of the humeral head, an associated fracture of the proximal part of the humerus, and the need for an arthroplasty.

Posterior dislocation and fracture-dislocation of the shoulder.

Two cases of posterior dislocation (PD) and four cases of posterior fracture-dislocation (PFD) of the shoulder are reported. There was one bilateral PD and two bilateral PFD. One PD was treated with closed reduction but in three cases of PFD operative reduction was necessary. All measures were applied in the late phase within 1 to 10 months after the injury with good primary results. However, because of posttraumatic arthrosis, the final result was poor. The average follow-up period was 4 years. The diagnosis of posterior dislocation is often missed. An axillary X-ray is essential.

[Bipolar dislocation of the forearm: elbow and perilunate dislocation].

We report a case of bifocal dislocation of the forearm due to posterior dislocation of the elbow and transcaphocapital retrolunate dislocation of the carpus, Fenton's syndrome, associated with fracture of both bones of the forearm. The emergency procedure achieved reduction of the elbow, plate fixation of the radius and ulna, used a posterior and an anterior access to achieve reduction and osteosynthesis of the radial styloid, the scaphoid, and the capitatum and temporary schapholunate, triquetrolunate, scaphocapitate, and radiolunate pinning. At ten months, the patient only complained of moderate pain for exceptional efforts. Complete amplitude elbow motion was restored. Wrist flexion and extension were 50 degrees and 30 degrees respectively. X-rays demonstrated union of the scaphoid and the capitatum. There was no scapholunate diastasis and the scapholunate angle was normal.

[An unusual dislocation of the elbow: convergent dislocation].

A case of dislocation of the elbow, combining convergent dislocation of the proximal radio-ulnar joint with posterior dislocation of the ulno-humeral joint was reported. This particular combination has not, to the knowledge of the authors, been reported previously. Diagnosis was based on anterioposterior X ray of the joint associated with a clinical finding of a loss of supination following reduction of the ulno-humeral joint. This unusual lesion has to be recognised for a missed diagnosis may lead to compromise of the result in the long term.

[Perilunar dislocations and dislocation fractures in polytrauma patients--diagnosis and therapy].

Between 1978 and 1987 about 700 multiply injured patients were treated at the Department of Emergency Surgery (University Hospital Hamburg-Eppendorf). Seven of these suffered from injuries of the wrist, in detail six perilunar dislocations with fractures of the scaphoid and one dislocation of the triquetrum. In six cases the correct diagnosis was found primarily by clinical and X-ray examinations. The real extent of one patient's wrist injury was revealed by control radiograms which were taken twelve weeks after the accident, when the patient was transferred to our hospital. Follow-up examinations were made at an average of 40 months after the injury. We suggest the following procedure in cases of perilunar dislocations: 1. Early closed reduction and prolonged immobilization in casts. 2. In cases where closed reduction cannot be achieved open reduction, pinning (Kirschner-wires) and immobilization should be performed. 3. Fractures of the scaphoid are provided with screws.

Traumatic dislocation and fracture dislocation of the hip. A long-term follow-up study.

Of 84 fracture dislocations of the hip reviewed, 73 were posterior fracture dislocations, nine were central, and two were obturator. Fifty-five were followed from one to 30 years (average, 4 1/2 years). The patients' ages ranged from three to 83 years (average, 33.1 years). All had primary attempt at closed reduction, with 15 treated with subsequent open reduction (six immediate and nine delayed). Satisfactory results were obtained in 42% of hips treated with closed reduction and 40% of those treated with open reduction. Statistical analysis of the results was done. A stable closed reduction produced results as satisfactory as open reduction. When followed for a sufficiently long time interval, severe fracture dislocations, regardless of treatment mode, caused unsatisfactory results.

[Reposition of old dislocations or dislocation fractures of the carpal bones using Wagner's distraction apparatus].

In treatment of old traumatic dislocations and fracture dislocations of the carpal bone complex, a careful and exactly dosed pre-extension of the shrunken capsular ligaments can be obtained by the use of Wagner's distraction apparatus. The pre-extension procedure is followed by open or closed reposition. The surgeon's movements are not hindered. Sterile draping of the operating field can easily be performed in contrast to other methods of reposition like hanging up the forearm with a counter-weight or olecranon-metacarpal extension with counter-traction. Up to 10 months after volar dislocation of the lunate bone the destructed carpal vault could be reconstructed.

[Radiographic diagnosis of dislocated inverted shoulder prosthesis: two cases of unrecognized dislocation].

Dislocation of inverted shoulder prostheses are rarely described in the literature. Diagnosis is relatively difficult as illustrated by two cases reported here which went unrecognized. The problem is the absence of any clear clinical sign of dislocation and the rather difficult interpretation of the radiographic images. We propose a method for analyzing the radiographic images which can be used to confirm the absence of dislocation on the AP view.

Anterior dislocation of the radial head with fractures of the olecranon and radial neck in a young child: a Monteggia equivalent fracture-dislocation variant.

We present a case of a type I Monteggia equivalent lesion in a 7-year-old child consisting of anterior dislocation of the radial head, radial neck fracture, and a fracture of the olecranon without an associated fracture of the ulnar diaphysis or metaphysis. After a review of the literature, we report this fracture pattern as a rare type I Monteggia equivalent fracture-dislocation variant. This report describes delayed surgical treatment and outcome after close follow-up of a rare type I Monteggia equivalent lesion. Diagnostic challenges with and treatment options for pediatric Monteggia equivalent fracture-dislocations are discussed.

Changes in the Burgers vector of perfect dislocation loops without contact with the external dislocations.

We report the observations of a new type of changing process in the Burgers vector of dislocations by in situ transmission electron microscopy. Small interstitial-type perfect dislocation loops in bcc iron with diameters less than approximately 50 nm are transformed from a 1/2<111> loop to another 1/2<111> one or an energetically unfavorable <100> one; furthermore, a <100> loop is transformed to a 1/2<111> one. These transformations occurred on high-energy electron irradiation or simple heating without contact with external dislocations. The origin of these phenomena is discussed.

[Perilunate dislocation and dislocation fractures--results of surgical management].

We report 22 patients who sustained a perilunate dislocation (PD) with or without a fracture of the scaphoid. The carpal ligaments were explored and reattached in all cases. The fractured scaphoid in perilunate fracture dislocations (PFD) was stabilised by a Herbert screw in 13 cases and in one case with a Matti-Russe bone graft. After an average of 5 years the clinical score of Green and O'Brien showed good results for both PD and PFD. Patients with PFD had less pain and better grip than the patients with PD. The sagittal range of motion (average between 70 degrees and 99 degrees) and the subjective limitation in sports and work were equal for PD and PFD. The only open injury (PD) had the worst clinical result. All patients with PD showed a carpal instability dissociative of the proximal row (CID) and an arthrosis of the radiocarpal joint. In the patients with PFD a CID could be seen in 78% and an arthrosis in 93%. A carpal collapse occurred in 75% of cases after PD and in 29% after PFD. In 57% of cases the PFD was accompanied by a disruption of the SL ligament. The anatomical reconstruction of the scaphoid is essential for good carpal alignment. The stable fixation of bony avulsions showed good results. A CID could not be avoided in any of our patients with PD.

Locked lateral patellar dislocation: a rare case of irreducible patellar dislocation requiring open reduction.

Irreducible patellar dislocations are rare injuries, but those that do occur are mainly directed intra-articularly. In this case, a 53-year-old woman sustained a locked lateral patellar dislocation when falling from a chair. A preoperative CT-scan revealed bony avulsions at the insertion of the vastus medialis muscle, the medical retinaculum, and partial disruption of the ligamentum patellae from the apex patellae. Open reduction was necessary and the torn structures were reattached with anchor systems and sutures. Postoperative management included intensive physiotherapy. At 1 year after surgery, the patient was without swelling or pain and had a normal gait, but flexion was restricted to 120 degrees. All postoperative radiographs showed the patella correctly placed in the femoral groove.

Traumatic posterior atlantooccipital dislocation with Jefferson fracture and fracture-dislocation of C6-C7: a case report with survival.

Atlantooccipital dislocation (AOD) is a rare and usually fatal injury. In the current study, the authors reported an extremely rare case of posterior AOD with Jefferson fracture and fracture-dislocation of C6-C7. The patient survived the injury and had only incomplete quadriplegia below the C7 segment with anterior cord syndrome. He was successfully managed with in situ occipitocervical fusion using the Cotrel-Dubousset rod system, corpectomy of C6, and anterior interbody fusion of C5-C7 with plating. To our knowledge, this is the first report of posterior AOD with two other non-contiguous cervical spine injuries. A high index of suspicion and careful examination of the upper cervical spine should be considered as the key to the diagnosis of AOD in cases that involve multiple or lower cervical spine injuries.

Dislocation and fracture-dislocation of the pelvis.

Dislocation and fracture-dislocation of the pelvis is a major injury; the force involved in its production may not only disrupt the pelvis but result in extensive associated injuries. Between 1960 and 1968, 43 patients with this injury were treated in the Accident Service of the Radcliffe Infirmary. Their case records and radiography have been analysed and 29 of the patients re-assessed at a follow-up examination.

Lisfranc dislocations: fractures and/or dislocations through the tarso-metatarsal joints.

Because of the anatomical configuration of the tarso-metatarsal joints with their strong ligamentous connections, pure dislocations in this region are rare. We describe our experience of 24 cases of Lisfranc dislocation. Classification is according to Wilson. In the long term, functional and radiological results appear to depend on the accuracy of reduction. For good anatomical results, immediate closed or, if necessary, open reduction and stabilization by percutaneous Kirschner wires is required. Because of the severity of soft tissue damage, decompression with dorsal skin incisions should also be considered.

Arthroscopically assisted reduction and percutaneous fixation of dorsal perilunate dislocations and fracture-dislocations.

Perilunate injuries are severe disruptions of the wrist joint that produce variable patterns of injury to the carpal anatomy. Most surgeons advocate an open reduction followed by ligament repair or internal fixation. We tried to reduce and fix the carpal bones under arthroscopic control to minimize surgical trauma and to preserve blood supply. While viewing the articular surface with the arthroscope, the disrupted proximal carpal row was anatomically reduced using Kirschner wires as joysticks, and fixed percutaneously without any repair of the capsuloligamentous tears. Three patients with dorsal perilunate dislocations or fracture-dislocations were treated by this technique. All the patients achieved accurate reduction and stable fixation, and showed successful healing of the carpal fractures with proper alignment after 10 to 12 weeks of immobilization. At 16 to 22 months follow-up, all patients showed normal radiographic findings with no evidence of instability or arthritis. The arthroscopic treatment of acute dorsal perilunate injuries is technically feasible in achieving anatomic reduction and stable fixation. Our preliminary clinical results were encouraging, but the long-term results need to be observed.
