Noninflammatory sclerosis of the sternal end of the clavicle: a follow-up study and review of the literature.

The cases of 14 adult females with swelling, tenderness, and sclerosis of the inferomedial part of the clavicle are presented. They were seen during a 16-year period, suggesting that the condition is rare. In ten patients strain at the sternoclavicular joint seemed to be an etiological factor. Eleven patients were followed for periods of 1-13 years (mean 5 years). The clavicular sclerosis regressed and they all developed signs of osteoarthrosis. Based upon available biopsy results and review of reported cases, it is hypothesized that the radiographic changes are due to osteonecrosis of the medial end of the clavicle with subsequent development of osteoarthrosis.

Stress fracture of the medial clavicle secondary to nervous tic.

The clinical and radiological characteristics of swelling in the region of the medial clavicle may suggest the presence of a neoplastic or inflammatory lesion. This report describes a 27-year-old man with a painful tumor-like lesion over the medial clavicle, which was found to be a stress fracture caused by a nervous tic resulting from mental stress.

Tuberculosis of the sternum and clavicle: imaging findings in 15 patients.

OBJECTIVE: To describe the imaging findings in sterno-clavicular tubercular involvement. DESIGN AND PATIENTS: Fifteen patients with pathologically proven tuberculosis of the sternum and clavicle were retrospectively evaluated. Routine radiography, computed tomography (CT) and magnetic resonance imaging (MRI) were used in some or all of the patients. Clinical information and imaging features were evaluated in each case. RESULTS: Eight patients had sternoclavicular joint (SCJ) involvement, five had isolated sternal involvement and two had isolated clavicular involvement. Seven patients were evaluated with only CT, six with only MRI and two with both. There were eight male and seven female patients, varying in age between 16 and 78 years. Fever, swelling and pain were common presenting symptoms. Two patients were HIV positive. Radiographs were positive in only eight patients. Destruction and signal intensity (SI) changes of the sternum and clavicle, destruction of the cartilage, soft tissue changes representing granulation tissue/abscess, displacement of the adjacent structures (vessels, trachea, etc.) and inflammatory changes in the adjacent structures in the form of cellulitis and myositis were common imaging features. CONCLUSIONS: All imaging methods can provide complementary information regarding sterno-clavicular tubercular involvement that is helpful for determination of the therapy. MRI is useful in determining the extent of the lesion, particularly marrow involvement and soft tissue extent.

Condensing osteitis of the clavicle in a man.

Condensing osteitis of the clavicle is a rare, benign, usually painful condition leading to sclerosis of the medial end of the clavicle. In the English language literature, this has only been reported in women since its original description by Brower et al. in 1974 [1]. We report a clavicular lesion occurring in a man that is clinically, radiographically, and histologically identical to described cases of condensing osteitis.

Fractures of the distal third of the clavicle treated by hook plating.

We retrospectively assessed the union and shoulder function following hook plate fixation in 18 patients with Neer type 2 fractures of the lateral end of the clavicle. The average age was 40 (range 22-62) years, and the mean follow-up was 25 (range 6-48) months. Fifteen patients had acute fractures and the rest were non-unions. Complications included two non-unions, one following a deep infection. There were no iatrogenic fractures. Acromial osteolysis was seen in five patients who had their plates in situ. The average pain score at rest was 1 (range 0-4), and the average pain score on abduction was 2.2 (range 0-5). The average Constant score was 88.5 (range 63-100). Patients were asked to rate their shoulder function; three rated it as normal, 11 as nearly normal and one as not normal. Hook plate fixation appears to be a valuable method of stabilising Neer type 2 fractures of the clavicle, resulting in high union rates and good shoulder function. These plates need to be removed after union to prevent acromial osteolysis.

Sports-related stress fracture of the clavicle: a case report.

Stress fracture of the clavicle is extremely rare, even in sports medicine. The authors have treated a young man who, for several years practised a traditional physical activity in which groups of people make human towers by standing on each others shoulders. For the last three years the patient experienced pain in the medial aspect of the right clavicle when he increased the intensity of his training. Bone scintigraphy revealed endosteal thickening which was indicative of a stress reaction. The mechanism of injury, the diagnosis of stress fracture, and a review of the literature are presented.

Results of the Bosworth method for unstable fractures of the distal clavicle.

Eleven consecutive Neer's type II unstable fractures of the distal third of the clavicle were treated by open reduction and internal fixation, using a temporary Bosworth-type screw. In all cases, fracture healing occurred within 10 weeks. Shoulder function was restored to the pre-injury level. A Bosworth-type screw fixation is a relatively easy and safe technique of open reduction and internal fixation of type II fractures of the distal third of the clavicle.

Posttraumatic nonunion of the clavicle in a 7-year-old girl.

An unusual case is reported of posttraumatic nonunion of the clavicle in a 7-year-old girl, which was treated by surgical stabilization with a Kirschner wire and apposition of cancellous bone chips taken from the proximal right tibial metaphysis. At clinical examination 2 years after surgery, the patient was symptom-free, and she had a full range of motion of the shoulder. Radiographs showed a very good remodeling of the bone, with only a minimal difference between the two clavicles.

Preliminary analysis of Nacholapithecus scapula and clavicle from Nachola, Kenya.

The Miocene ape Nacholapithecus is known from rather complete skeletons; some of them preserve the shoulder joint, identified by three scapulae and one clavicle. Comparisons made with other Miocene and living apes ( Proconsul, Equatorius, Ugandapithecus) suggest that the mobility of the scapulohumeral joint was important, and scapular features such as the morphology and position of the spine and the morphology of the acromion and axillary border resemble those of climbing arboreal primates except for chimpanzees, gorillas, or orang-utans. From the size of the scapula (male Nasalis size), it is clear that the animal is smaller than an adult chimpanzee, but the clavicle is almost as relatively long as those of chimpanzees. Some features closer to colobine morphology reinforce the hypothesis that Nacholapithecus was probably a good climber and was definitely adapted for an arboreal life.

Serratia marcescens osteomyelitis of the clavicle and sternoclavicular arthritis complicating infected indwelling subclavian vein catheter.

Serratia marcescens bacteremia, osteomyelitis of the right clavicle, and septic arthritis of the right sternoclavicular joint developed in a 69-year-old woman after a right subclavian vein catheter was in place for five days. The infections were cured with the combination of gentamicin and ceftizoxime. There have been three previously reported cases of osteomyelitis of the clavicle following indwelling subclavian vein catheterization; two were caused by Staphylococcus aureus and one by Pseudomonas aeruginosa.

Vascularised reconstruction of the clavicle.

A rare malignant tumour presented as a pathological fracture in the clavicle of an 11-year-old girl. This was resected and the defect reconstructed using a pedicled bilobed flap based on the thoracodorsal system with latissimus dorsi and serratus anterior with a rib to replace the clavicle. The innervation of both donor muscles was preserved. The reconstruction was cosmetically acceptable and maintained the function of the thoracohumeral articulation. Although the use of vascularised rib grafts in composite flaps is well documented, this is the first report of clavicular reconstruction using the technique.

Complications of fractures of the clavicle.

Most fractures of the clavicle unite without incident. The number and diversity of the methods of treatment in use suggest that in most cases good results are obtained despite medical supervision. Yet occasionally complications do arise. This paper describes two such cases and reviews the literature in search of a common factor to account for these complications. Cases presenting with early and late complications of fractures of the clavicle are described and the literature on the subject reviewed. The incidence of complications is highest in cases of direct violence to the shoulder region producing comminuted fractures. Surgical management is outlined in general terms. It is suggested that more prolonged and rigorous immobilization of cases "at risk" may reduce the incidence of non-union and prevent late neurovascular complications.

Post-traumatic reactive and resorptive lesions of the medial end of the clavicle.

Three soldiers presented with a painful swelling of the sternoclavicular area. Computed tomography (CT) studies showed sclerosis as well as lysis of the medial end of the clavicle with adjacent soft-tissue swelling. Bone biopsy revealed new bone formation and inflammatory reaction; cultures were negative, no tumor cells were found. The patients recovered after antibiotic treatment. Although the CT findings cannot completely rule out a malignant lesion, these changes in the medial end of the clavicle in young people may suggest trauma as the etiology.

Acromioclavicular stability: a biomechanical comparison of acromioplasty to acromioplasty with coplaning of the distal clavicle.

PURPOSE: The purpose of the study was to compare the laxity of the acromioclavicular (AC) joint in the superior, posterior, and anterior planes after isolated acromioplasty and after acromioplasty with inferior clavicular coplaning. TYPE OF STUDY: In vitro (cadaveric) analysis. METHODS: Eight fresh-frozen cadaveric shoulders were evaluated using a hydraulic actuator. While the scapula was stabilized, a 30-N force was applied to the distal clavicle perpendicular to the AC joint in the superoinferior plane and parallel to the joint in the anteroposterior plane. Laxity of the AC joint in the superior, anterior, and posterior directions was evaluated via load-displacement analysis after acromioplasty and after acromioplasty with coplaning. RESULTS: Coplaning the distal clavicle increased superior AC laxity by 53% compared with acromioplasty alone (P =.012). With regard to anteroposterior laxity, coplaning increased anterior translation by 19% (P =.047) and increased posterior translation by 16% (P =.237). Bony impingement was seen to limit posterior translation in 3 specimens. CONCLUSIONS: Acromioplasty with coplaning increases AC laxity significantly in the superior and anterior directions as compared with acromioplasty alone. A trend toward increased posterior translation was found; posterior bony impingement may limit posterior laxity.

Oklahoma prosthesis: resection of tumor of clavicle and chest wall reconstructed with a custom composite graft.

Tumors involving the clavicle by primary or metastatic growth may require clavicular resection often with rib resection. The resulting cosmetic and functional impairment of clavicular resection may be significant with a sloped appearing shoulder girdle and chronically impaired movement of the upper extremity. We report a 48-year-old woman presenting with a bulky metastatic renal cell mass of her left clavicle extending to the chest wall. We report en-bloc clavilculectomy and chest wall resection with a novel method of reconstruction using a single methyl methacrylate and prolene composite prosthesis in a configuration resembling the state of Oklahoma.

Painful sclerosis of the medial end of the clavicle.

Pain and swelling of the medial end of the clavicle may be associated with radiographic sclerosis. The commonest causes are osteoarthritis, infection and condensing osteitis of the clavicle. Distinguishing between these clinically and radiologically can be difficult but computed tomography (CT) and magnetic resonance imaging (MRI) are often useful for their differentiation. In this review, the typical imaging features of these conditions are presented with an emphasis on the CT and MRI appearances. These are correlated with clinical features, which together should enable a confident diagnosis to be made.

Intramedullary fixation of Neer type 2 fractures of the distal clavicle with an AO/ASIF screw.

BACKGROUND: Neer 2 fractures of the distal clavicle are notorious for their high rates of non-union and numerous methods of fixation are recommended. We review a simple method of fixation of these fractures with an intramedullary AO/ASIF malleolar screw. METHOD: Ten patients with Neer type 2 fractures of the distal clavicle were treated between 1996 and 2002. All had open reduction and internal fixation with an intramedullary 4.5 mm AO/ASIF malleolar screw. In all cases the coraco-clavicular ligaments were not repaired, and the screws were removed once the fractures had united. RESULTS: All fractures united at between 6 and 12 weeks. All patients had a good functional result, with an excellent to good Oxford Shoulder score. CONCLUSION: This is a simple technique with a universally available implant and good fracture healing. We report no cases of screw breakage or migration and we question the necessity to repair the coraco-clavicular ligaments.

Chronic osteomyelitis of clavicle as primary manifestation of SAPHO syndrome in adolescents: report of four cases and long-term evolution.

Four cases of chronic osteomyelitis of clavicle as primary manifestation of synovitis, acne, pustulosis, hyperostosis, osteomyelitis (SAPHO) are reported in adolescents. In all cases a typical radiographical evolution had been observed with progressive slow migration of sclerotic area from medial to lateral side of clavicle. Long-term evolution was alternation of remission and exacerbation but none of the patients healed.
