[Treatment of acromioclavicular joint dislocation with the Rahmanzadeh joint plate].

Type Tossy III dislocations of the acromioclavicular joint (AC) are treated surgically in German-speaking countries. There is considerable rotation and tilting in the AC joint with elevation or abduction of the shoulder joint over 90 degrees. Thus, in the majority of countless surgical procedures, the abduction and elevation are restricted or immobilized for long periods in abduction strapping or other types of movement restriction. The AC joint plate developed by Prof. Rahmanzadeh enables early functional, complete physical therapy since the plate permits rotation and tilting. Over a period of 13 years, 133 patients have been treated with this plate. 83 patients could be included in the follow-up examination. On the average, the follow-up was 4.8 years after surgery. In the evaluation score according to Taft et al., 76% of the patients in the follow-up showed very good or good results. The surgical procedure is standardized and will show that no immobilization is required postoperatively. It could already be seen of the first postoperative day that patients could passively elevate up to 90 degrees. At the latest, free active abduction and elevation are reached after 5 weeks. Material removal should take place after 12 weeks. Due to the limited tissue covering in the area of the AC joint, a higher rate of infection can be expected than in other osteosyntheses. However, there were no persistent infections. Transitory problems in the implantation were remedied by constructive changes in the course of its development. Rahmanzadeh's AC plate is outstandingly suited for surgical treatment of type Tossy III AC joint injuries and for the treatment of lateral clavicle fractures.

Simultaneous dorsal dislocation of the interphalangeal joints in ring finger with proximal interphalangeal joint dislocation of the middle finger: case report and review of the literature.

A 30-year-old amateur goalkeeper sustained simultaneous dislocation of the proximal and distal interphalangeal joints of the ring finger and of the proximal interphalangeal joint of the middle finger following a hyperextension injury. This was reduced under a local anaesthetic. Neighbour finger strapping and early mobilisation achieved an excellent functional outcome when reviewed at eight weeks after the initial injury.

Subtalar joint dislocations.

Dislocations of the subtalar joint are rare injuries. The anatomy, pathophysiology, treatment, and prognosis of subtalar joint dislocations have been well described in the literature. The purpose of this paper is to review the current literature on subtalar joint dislocations, as well as outline those aspects of the anatomy, pathomechanics, and treatment pertinent to care of the patient with subtalar joint dislocation. In addition, complications and obstacles to reduction are described. Subtalar joint dislocations, although not common, have increased in frequency over the last decade. Generally, they can be treated successfully with closed reduction and a short period of cast immobilization. The majority of patients will suffer some disability with subtalar joint stiffness the primary complaint. Associated intra-articular fractures increase the risk of posttraumatic arthrosis.

Lateral subtalar joint dislocation: a case with calcaneal fracture.

Subtalar joint dislocation is a relatively rare injury, with lateral dislocation occurring less frequently than medial dislocation. Associated fractures alter the treatment plan and the prognosis, but they are often missed on plain film radiographs. A brief review of the anatomy, pathomechanics, treatment, prognosis, and complications of subtalar joint dislocation is presented. An interesting case of lateral subtalar joint dislocation with an associated calcaneal fracture not evident on plain film radiographs but delineated with computed tomography is presented.

A method for open reduction and internal fixation of the unstable posterior sternoclavicular joint dislocation.

Posterior sternoclavicular joint (SCJ) dislocations are most often stable after reduction but may be associated with significant complications related to the location of the medial head of the clavicle within the mediastinum. In rare instances, a posterior SCJ dislocation is irreducible or redislocates after a closed reduction. Because of the potential hazards related to compression of vital structures within the superior mediastinum, open reduction and internal fixation is usually required. Although open reduction is widely accepted as the method of choice, the best method for achieving stable fixation remains unanswered. We present the case of an unstable SCJ stabilized, in anatomic position, with two large-bore cannulated screws in conjunction with open reduction. We believe that the risk of hardware migration reported with the use of pins and wires and its catastrophic complications are greatly minimized using our technique.

Posterior sternoclavicular joint dislocation in children-role of spiral computed tomography.

Traumatic posterior dislocation of the sternoclavicular joint is an uncommon injury in children. It is not normally well seen on plain films. We report 2 cases where spiral computed tomography with intravenous contrast confirmed the clinical suspicion of sternoclavicular joint dislocation and also allowed assessment of the adjacent mediastinum for possible complications. Emergency physicians should be aware that the use of spiral computed tomography is the procedure of choice in posterior sternoclavicular joint dislocation. This is particularly helpful in allowing multiplanar reconstruction to show complications arising in the mediastinum.

Biomechanical function of surgical procedures for acromioclavicular joint dislocations.

PURPOSE: Surgical procedures for treatment of acromioclavicular (AC) joint dislocation replace the coracoclavicular (CC) ligaments to minimize motion, allow scarring, and increase the subsequent stability of the joint. The purpose of this study was to evaluate the biomechanical function of the surgically repaired or reconstructed (CC Sling, Rockwood Screw [DePuy Orthopaedics, Warsaw, IN], and Coracoacromial [CA] Ligament Transfer Construct) AC joint after AC joint dislocation. TYPE OF STUDY: A cadaver study using a convenience sample. METHODS: Twelve cadaveric shoulders were tested using a robotic/UFS testing system. Three external loading conditions (anterior, posterior, or superior load of 70 N) were applied to intact and surgically repaired or reconstructed AC joint. The resulting kinematics of the AC joint and in situ forces in the CC ligaments or surgical constructs was determined. RESULTS: For the CC Sling, anterior and posterior translation significantly increased by 110% and 330% in response to an anterior and posterior load, respectively. However, the posterior translation for the Rockwood Screw significantly decreased by 60%. Anterior, posterior, and superior translation for the CA Ligament Transfer Construct significantly increased by 110%, 360%, and 100%, respectively. The coupled translations also significantly increased for the CC Sling and CA Ligament Transfer Construct in response to all loading conditions. In contrast, the coupled translations for the Rockwood Screw tended to decrease. Furthermore, the in situ forces increased significantly for all 3 surgical constructs compared with the intact CC Ligaments in response to an anterior and posterior load. CONCLUSIONS: At time zero, increases in the primary and coupled motion for the CC Sling and CA Ligament Transfer Construct could comprise the initial healing period prescribed for AC joint dislocation. Our findings also suggest that the Rockwood Screw provides a highly rigid fixation and may explain the complications frequently seen in clinical practice. CLINICAL RELEVANCE: Current surgical procedures do not have the appropriate stiffness to restore the stability of the intact joint before healing. Therefore, our results may lead to the design and development of new repairs, reconstructions, and rehabilitation protocols for AC joint dislocation.

Manubriosternal joint dislocation in contact sport.

A 17 year old man developed chest pain and shortness of breath immediately after a scrummage while playing rugby football. A lateral chest radiograph showed a dislocated manubriosternal joint, with no associated injuries. This has not been previously reported in a sporting setting. This injury should be considered in flexion-compression injury of the thorax.

An isolated ring finger metacarpal shaft fracture?--beware an associated little finger carpometacarpal joint dislocation.

Dislocations of the ulnar carpometacarpal joint are easily missed because of a low index of suspicion as well as their subtle clinical and radiological features. Often, the presence of a more obvious adjacent injury also draws attention away from the carpometacarpal joint. Two cases of ring finger metacarpal shaft fractures with associated little finger carpometacarpal joint dislocations are presented. In both cases, the metacarpal fractures were diagnosed but the carpometacarpal joint dislocations were initially overlooked. The presence of an apparently isolated ring finger metacarpal fracture due to an indirect force should raise the possibility of an associated carpometacarpal joint injury.

[Injuries of the major blood vessels in joint dislocations].

Experience with the treatment of 12 patients with injuries of major vessels resulting from dislocations of joints is generalized. In 5 of the patients an associated injury of nerve trunks was diagnosed, in 4 patients there were injuries of major veins. Reconstructive operations were made in 11 patients. In 8 patients full recovery was stated, three patients were subjected to amputation of the extremity. The main cause of the failure was late diagnosis of the closed trauma of the artery and progressing ischemia of the extremity.

A case series of closed reduction for acute temporomandibular joint dislocation by a new approach.

OBJECTIVE: The management of acute temporomandibular joint dislocation relies on the traditional method, which involves intraoral manipulation of the mandible on both sides of the patient. Often, intravenous sedative or analgesic agents are needed to facilitate closed reduction. In this report, the authors introduce a new approach called the ipsilateral approach, in which extraoral or intraoral manipulation of the dislocated side is performed to accomplish closed reduction, without using sedatives or analgesics. Three methods, namely, extraoral, intraoral and combined, are described. METHODS: A prospective observational study was performed to investigate this ipsilateral approach. Six medical officers were recruited to attend to patients with acute temporomandibular joint dislocation. The following protocol was used: (1) Try the extraoral method in all patients first. (2) If it fails, use the intraoral method. (3) If both fail, attempt using a combined method. (4) If all fail, perform the traditional method as usual. RESULTS: A total of 24 episodes of temporomandibular joint dislocation were examined, out of which 13 were successfully reduced by the extraoral method. Of the remaining 11 episodes, 10 were successfully reduced by the intraoral method, the last case being reduced by the combined method. None of them requires sedation or analgesia. CONCLUSION: This ipsilateral approach, using extraoral and intraoral methods, is cost-effective, simple and convenient for the management of acute temporomandibular joint dislocation.

Biomechanical rationale for development of anatomical reconstructions of coracoclavicular ligaments after complete acromioclavicular joint dislocations.

BACKGROUND: Surgical treatments of complete acromioclavicular joint dislocations replace or reconstruct the coracoclavicular ligaments with a single structure and do not account for the anatomical variance of each ligament in the design. PURPOSE: To evaluate the cyclic behavior and structural properties of an anatomic tendon reconstruction of the coracoclavicular ligament complex after a simulated acromioclavicular joint dislocation. STUDY DESIGN: Controlled laboratory study. METHODS: Cyclic loading followed by a load-to-failure protocol (simulated dislocation) of the normal coracoclavicular ligament complex was performed and repeated after an anatomic reconstruction on the same specimen (n = 9). The anatomical reconstruction consisted of a semitendinosus tendon that replicated the direction and orientation of both the trapezoid and conoid ligaments. RESULTS: The coracoclavicular ligament and anatomical reconstruction complexes had clinically insignificant (<3 mm) permanent elongation after cyclic loading. The stiffness and ultimate load of the coracoclavicular ligament complex (60.8 +/- 12.2 N/mm and 560 +/- 206 N) were significantly greater than for the anatomical reconstruction complex (23.4 +/- 5.2 N/mm and 406 +/- 60 N), respectively (P < .05). Further analysis of the complexes revealed a 40% decrease in the bending stiffness of the clavicle after the simulated dislocation and failure of the normal coracoclavicular ligament complex (P < .05), which contributed to the diminished properties of the anatomic reconstruction. CONCLUSIONS: The low level of permanent elongation after cyclic loading suggests that the anatomic reconstruction complex could withstand early rehabilitation; however, the decrease in the structural properties and stiffness of the clavicle should be considered in optimizing the anatomic reconstruction technique. CLINICAL RELEVANCE: Despite the differences compared to the normal coracoclavicular ligament complex, the anatomical reconstruction complex more closely approximates the stiffness of the coracoclavicular ligament complex than current surgical constructs, and the incorporation of biological tissue could improve the overall structural properties with healing.

Surgical correction of metatarsophalangeal joint dislocation and arthritic deformity: the partial head and plantar condylectomy.

The partial head and plantar condylectomy has been presented as a procedure indicated in the correction of dislocated metatarsophalangeal joints. Although there may be a number of causes of dislocation, the surgical correction is the same. A skin plasty is useful in preventing a cocked-up toe, and this is performed at the plantar aspect of the base of the toe. A V-osteotomy, or other metatarsal dorsiflectory procedure, is recommended when the neighboring metatarsal is only slightly plantar flexed or greater. This prevents the occurrence of transfer lesions so commonly associated with this procedure. Two case studies have been presented demonstrating successful results when the procedure is performed on both the second and third metatarsophalangeal joints. We contend that the partial head and plantar condylectomy is a valuable procedure in reconstructive surgery of the foot.

Posterior sternoclavicular joint dislocation: the value of intra-operative ultrasound.

The sternoclavicular joint dislocates posteriorly if the costoclavicular ligaments, posterior capsule, and anterior capsule have all been disrupted. Diagnosis of a posteriorly dislocated sternoclavicular joint is difficult on clinical examination and with plain X-rays. The treatment objective is to obtain a closed reduction, and failing this an open reduction is indicated. In the intra-operative setting the evaluation of the reduction when performed through closed means can be somewhat difficult, and intra-operative plain films do not give clear answers. Ultrasound as an imaging modality for these injuries was shown to demonstrate the state of the joint in terms of reduction, more clearly than X-rays (P<0.001). It was accurately interpreted by the vast majority of orthopaedic surgeons in an investigation, and is of great value in the intra-operative setting to confirm whether a closed reduction has been successful or not. A case is reported illustrating its use.

Arthroscopic reconstruction for acromioclavicular joint dislocation.

We describe an arthroscopic reconstruction technique for acromioclavicular joint dislocation. Subsequent to Baum's first repair of the coracoclavicular complex in 1886, over 60 operative procedures have been described in the literature. This procedure is the first described arthroscopic approach used in reconstruction for acromioclavicular dislocation. It provides an anatomically correct and structurally sound reconstruction of the coracoclavicular ligament complex. This arthroscopic technique is also a cosmetically pleasing alternative to previously described open procedures for reconstruction of acromioclavicular joint dislocations. As with most arthroscopic procedures, this technique achieves its goals with minimal morbidity and violation of the surrounding soft tissues.
