Aims. There remains a lack of consensus regarding the management of chronic anterior sternoclavicular joint (SCJ) instability. This study aimed to assess whether a standardized treatment algorithm (incorporating physiotherapy and surgery and based on the presence of trauma) could successfully guide management and reduce the number needing surgery. Methods. Patients with chronic anterior SCJ instability managed between April 2007 and April 2019 with a standardized treatment algorithm were divided into non-traumatic (offered physiotherapy) and traumatic (offered surgery) groups and evaluated at discharge. Subsequently, midterm outcomes were assessed via a postal questionnaire with a subjective SCJ stability score, Oxford Shoulder Instability Score (OSIS, adapted for the SCJ), and pain visual analogue scale (VAS), with analysis on an intention-to-treat basis. Results. A total of 47 patients (50 SCJs, three bilateral) responded for 75% return rate. Of these, 31 SCJs were treated with physiotherapy and 19 with surgery. Overall, 96% (48/50) achieved a stable SCJ, with 60% (30/50) achieving unrestricted function. In terms of outcomes, 82% (41/50) recorded good-to-excellent OSIS scores (84% (26/31) physiotherapy, 79% (15/19) surgery), and 76% (38/50) reported low pain VAS scores at final follow-up. Complications of the total surgical cohort included a 19% (5/27) revision rate, 11% (3/27) frozen shoulder, and 4% (1/27) scar sensitivity. Conclusion. This is the largest midterm series reporting chronic anterior SCJ instability outcomes when managed according to a standardized treatment algorithm that emphasizes the importance of appropriate patient selection for either physiotherapy or surgery, based on a history of trauma. All but two patients achieved a stable SCJ, with stability maintained at a median of 70 months (11 to 116) for the physiotherapy group and 87 months (6 to 144) for the surgery group.

Sternoclavicular joint infections are uncommon but severe and complex condition usually in medically complex and compromised hosts. These infections are challenging to treat with risks of infection extending into the mediastinal structures and surgical drainage is often faced with problems of multiple unplanned returns to theatre, chronic non-healing wounds that turn into sinus and the risk of significant clinical escalation and death. Percutaneous aspirations or small incision drainage often provide inadequate drainage and failed control of infection, while open drainage and washout require multidisciplinary support, due to the close proximity of the mediastinal structures and the great vessels as well as failure to heal the wounds and creation of chronic wound or sinus. We present our series of 8 cases over 6 years where we used the plan of open debridement of the Sternoclavicular joint with medial end of clavicle excision to allow adequate drainage. The surgical incision was not closed primarily, and a suction vacuum dressing was applied until the infection was contained on clinical and laboratory parameters. After the infection was deemed contained, the surgical incision was closed by local muscle flap by transferring the medial upper sternal head of the Pectoralis Major muscle to fill in the sternoclavicular joint defect. This technique provided a consistent and reliable way to overcome the infection and have the wound definitively closed that required no secondary procedures after the flap surgery and no recurrence of infections so far. We suggest that open and adequate drainage of Sternoclavicular joint staged with vacuum dressing followed by pectoralis major local flap is a reliable technique for achieving control of infection and wound closure for these challenging infections

The sternoclavicular joint is vulnerable to the same disease processes as other synovial joints, the most common of which are instability from injury, osteoarthritis, infection and rheumatoid disease. Patients may also present with other conditions, which are unique to the joint, or are manifestations of a systemic disease process. The surgeon should be aware of these possibilities when assessing a patient with a painful, swollen sternoclavicular joint

We describe a new method of stabilising a painful unstable sternoclavicular joint using the sternocleidomastoid tendon and passing it through the medial clavicle and onto the manubrium sternum. This method is simple, reproducible and avoids the potential risks of reefing the joint to the first rib. The technique was used in seven cases of sternoclavicular joint instability in six patients who were reviewed at a mean of 39.7 months (15 to 63). Instability was markedly reduced or eliminated in all cases, but in one there was occasional persistant subluxation. There were minor scar complications after two procedures and one patient had transient ulnar neuritis. This procedure provides satisfactory results in the medium term

This study describes the method and results of a new way of stabilising painful unstable sternoclavicular joints using the sternocleidomastoid tendon. Painful instability of the sternoclavicular joint is a rare condition whose cause is either of spontaneous onset in young principally females with generalised joint laxity or of traumatic onset. The direction of instability can be anterior, superior or posterior. Surgical stabilisation is difficult and has principally consisted of using periosteum or subclavius and reefing the joint to the first rib with its attendant risks and variable results. We describe eight cases of painful sternoclavicular joint instability treated by using the sternocleidomastoid tendon and passing it through the medial clavicle and onto the manubrium of the sternum to stabilise the joint. This method of treatment is simpler, is reproducible and avoids the potential risks of reefing the joint to the first rib. There is no decrease in function of the sternocleidomastoid muscle from this procedure. All directions of instability can be treated using this tendon by varying the position of the bone hole. The results show comparable outcome for stability with other studies. We conclude that using the sternocleidomastoid tendon to stabilise the sternoclavicular joint is a simpler and safer method of treating these injuries and gives comparable results to the other methods of surgical stabilisation

Osteoarthritis (OA) is the most common disorder of the Sternoclavicular Joint (SCJ). In our case-control study, we evaluated the relationship between clavicular length and OA at the SCJ. CT scans of adults presenting to the Emergency Department of our hospital were examined to look for OA, defined as the presence of osteophytes, subchondral cysts, or cortical sclerosis at the SCJ. Medial-most and lateral-most points of the clavicle were marked on the slices passing through the SC and AC joints respectively. Using x, y, and z-axis coordinates from the DICOM metadata, clavicular length was calculated as the distance between these two points with 3D geometry. Preliminary data of 334 SCJs from 167 patients (64% males, 36% females) with a mean age of 48.5 ± 20.5 years were analysed. Multivariate regression models revealed that age and clavicular length were independent risk factors for OA while gender did not reach statistical significance. A 1mm increase in length was associated with 9% and 7% reduction in the odds of developing OA on the left and the right respectively. Comparing the mean clavicular length using t-test showed a significantly shorter clavicle in the group with OA (145.8 vs 152.7, p=0.0001, left and 144.2 vs 150.3, p=0.0007, right). Our data suggest that the risk of developing OA at the SCJ is higher for shorter clavicles. This could be of clinical relevance in cases of clavicular fracture where clavicular shortening might lead to a higher risk of developing OA. Biomechanical studies are needed to find out the mechanism of this effect

We describe the mid-term clinical results of the surgical treatment of primary degenerative arthritis of the sternoclavicular joint in eight women. They had not responded to conservative treatment and underwent a limited resection arthroplasty. For pre-and postoperative clinical evaluation we used the Rockwood score for the sternoclavicular joint. Postoperatively, the Constant score was also determined. The mean follow-up was 31 months (10 to 82). The median Rockwood score increased from 6 to 12.5 points. The median postoperative Constant score was 87 (65 to 91). Four patients had an excellent, three a good, and one a poor result. All patients were pleased with the cosmetic result. Resection arthroplasty is an effective and safe treatment for chronic, symptomatic degenerative arthritis of the sternoclavicular joint with a high degree of patient satisfaction

We retrospectively analysed the clinical results of 30 patients with injuries of the sternoclavicular joint at a minimum of 12 months’ follow-up. A closed reduction was attempted in 14 cases. It was successful in only five of ten dislocations, and failed in all four epiphyseal disruptions. A total of 25 patients underwent surgical reduction, in 18 cases in conjunction with a stabilisation procedure. At a mean follow-up of 60 months, four patients were lost to follow-up. The functional results in the remainder were satisfactory, and 18 patients were able to resume their usual sports activity at the same level. There was no statistically significant difference between epiphyseal disruption and sternoclavicular dislocation (p > 0.05), but the functional scores (Simple Shoulder Test, Disability of Arm, Shoulder, Hand, and Constant scores) were better when an associated stabilisation procedure had been performed rather than reduction alone (p = 0.05, p = 0.04 and p = 0.07, respectively). We recommend meticulous pre-operative clinical assessment with CT scans. In sternoclavicular dislocation managed within the first 48 hours and with no sign of mediastinal complication, a closed reduction can be attempted, although this was unsuccessful in half of our cases. A control CT scan is mandatory. In all other cases, and particularly if epiphyseal disruption is suspected, we recommend open reduction with a stabilisation procedure by costaclavicular cerclage or tenodesis. The use of a Kirschner wire should be avoided

The sternoclavicular joint (SCJ) is a pivotal articulation in the linked system of the upper limb girdle, providing load-bearing in compression while resisting displacement in tension or distraction at the manubrium sterni. The SCJ and acromioclavicular joint (ACJ) both have a small surface area of contact protected by an intra-articular fibrocartilaginous disc and are supported by strong extrinsic and intrinsic capsular ligaments. The function of load-sharing in the upper limb by bulky periscapular and thoracobrachial muscles is extremely important to the longevity of both joints. Ligamentous and capsular laxity changes with age, exposing both joints to greater strain, which may explain the rising incidence of arthritis in both with age. The incidence of arthritis in the SCJ is less than that in the ACJ, suggesting that the extrinsic ligaments of the SCJ provide greater stability than the coracoclavicular ligaments of the ACJ. Instability of the SCJ is rare and can be difficult to distinguish from medial clavicular physeal or metaphyseal fracture-separation: cross-sectional imaging is often required. The distinction is important because the treatment options and outcomes of treatment are dissimilar, whereas the treatment and outcomes of ACJ separation and fracture of the lateral clavicle can be similar. Proper recognition and treatment of traumatic instability is vital as these injuries may be life-threatening. Instability of the SCJ does not always require surgical intervention. An accurate diagnosis is required before surgery can be considered, and we recommend the use of the Stanmore instability triangle. Most poor outcomes result from a failure to recognise the underlying pathology. There is a natural reluctance for orthopaedic surgeons to operate in this area owing to unfamiliarity with, and the close proximity of, the related vascular structures, but the interposed sternohyoid and sternothyroid muscles are rarely injured and provide a clear boundary to the medial retroclavicular space, as well as an anatomical barrier to unsafe intervention. This review presents current concepts of instability of the SCJ, describes the relevant surgical anatomy, provides a framework for diagnosis and management, including physiotherapy, and discusses the technical challenges of operative intervention.

Introduction Displaced fractures of the midshaft clavicle often results in malunion with angulation and foreshortening. The purpose of this study is to determine the secondary effects of clavicular shortening on the sternoclavicular joint and scapulo-thoracic relationship, and to evaluate the symptomatic and biomechanical outcome in these patients. Methods A series of 10 patients each with a malunited fractured clavicle defined by relative shortening of more than 15 mm were examined. A self-administered questionnaire for assessment of symptoms and function of the ipsilateral shoulder was completed for each patient. Computer tomography and three dimensional reconstructions of both shoulders were undertaken for static anatomical measurements. Biomechanical testing comparing both shoulders in each patient measured strength and velocity of movement. All subjects were symptomatic in the injured shoulder. Results There were statistically significant differences between injured and uninjured shoulders for both mean shoulder scores and visual analog global assessments of shoulder function. Clavicular shortening produced statistically significant increased upward angulation of the clavicle at the sternoclavicular joint (p< 0.005), increased lateral displacement of the scapula on the posterior wall, and anterior scapular version (p< 0.05). Biomechanical differences were also recorded including a reduction in muscular strength for adduction, extension, and internal rotation of the humerus and also a reduced peak abduction velocity in the injured shoulder (p< 0.05). Conclusions Changes in static sternoclavicular and scapulothoracic relationships occur following short malunion of the clavicle and are possible mechanisms limiting shoulder function after this injury. This study provides evidence that consideration should be given to prevention of clavicle malunion by open reduction and internal fixation, especially in the young and active age group

1. Two patients with retrosternal dislocation of the clavicle are reported. 2. A method of closed reduction is described. 3. Diagnosis, and the interpretation of oblique radiographs of the sternoclavicular joint, are described

Traumatic posterior dislocation of the sternoclavicular joint is an unusual injury. We report a rare, late complication in the form of a thoracic outlet syndrome. Resection of the first rib resulted in prompt and complete resolution of the symptoms and would appear to be the appropriate treatment, avoiding the complications associated with resection of the clavicle

We describe a method for approaching the lower cervical and upper thoracic spine, the brachial plexus and related vessels. The method involves the elevation of the medial corner of the manubrium, the sternoclavicular joint, and the medial half of the clavicle on a pedicle of the sternomastoid muscle. We have used this exposure in 17 cases with few complications and good results. Its successful performance requires high standards of anaesthesia, surgical technique and postoperative care

Twelve patients were operated upon after unsuccessful conservative treatment for complete dislocation of the sternoclavicular joint. Three methods were used; stabilisation using fascial loops, reconstruction with a tendon graft, and resection of the sternal end of the clavicle. The results were good in only four patients, three treated with a tendon graft and one by fascial loops. Another four patients had fair results, but all four treated by resection of the medial end of the clavicle had poor results, with pain and weakness of the upper extremity. In our opinion resection of the sternal end of the clavicle should not be used in old traumatic dislocation

Traumatic injuries to the sternoclavicular joint (SCJ) are uncommon representing only 3% of all injuries to the shoulder girdle. Acutely, the majority are managed non-operatively with physiotherapy rehabilitation. However, if there is evidence of neurovascular compromise emergency reduction is indicated. There is no consensus on treatment of SCJ dislocations and subluxations that remain symptomatic after conservative treatment. Multiple surgical techniques have been described to alleviate this problem. These include resection of the medial end of the clavicle and various stabilization techniques using Kirschner wires, muscle tendon (subclavius, sternocleidomastoid, semi-tendinosus and palmaris longus) and synthetic materials (Dacron). However, all techniques have reported problems in terms of pain, decreased range of movement and a relatively high complication rate. We report a new technique using a LARS® ligament (Ligament Augmentation and Reconstruction System) with good early post-operative results. 5 symptomatic SCJ dislocations were repaired over a 3 year period. The operations were conducted by the same surgeon and at the same unit. The patients were on average 20 years old (17–22). Mean follow up time was 21 months (9–41). Functional assessment was made using the DASH (Disabilities of the Arm, Shoulder and Hand) and the OSS (Oxford Shoulder Score) outcome measures. An improvement between pre- and post-operative scoring was observed in both DASH median 51.7 (24.2–75.0) v 13.7 (8.3–20.8) (p=0.024) and OSS 20.6 (15–32) v 41.8 (39–47) (p<0.001). One patient had a pneumothorax intra-operatively but this resolved with conservative treatment. There were no long term complications experienced during follow up
