Distal Clavicle Osteochondroma Causing Supraspinatus Tendinopathy.

Shoulder pain is a very common symptom especially in young and active population. Rotator cuff tendinopathies are believed to be the most common cause of shoulder pain up to 86%. Tumors around the shoulder area can cause pain or joint stiffness when expanding in the subacromial space. We present a rare case of a distal clavicle osteochondroma. It is a benign tumor which in this area causes supraspinatus tendinopathy and every physician should suspect this kind of diseases during the diagnostic approach of a shoulder pain. In this case, early diagnosis and appropriate treatment with excision of the lesion gave us a very good outcome with fully relief of the symptoms.

Ball-joint versus single monolateral external fixators for definitive treatment of tibial shaft fractures.

PURPOSE: To compare modular monolateral external fixators with single monolateral external fixators for the treatment of open and complex tibial shaft fractures, to determine the optimal construct for fracture union. MATERIALS AND METHODS: A total of 223 tibial shaft fractures in 212 patients were treated with a monolateral external fixator from 2005 to 2011; 112 fractures were treated with a modular external fixator with ball-joints (group A), and 111 fractures were treated with a single external fixator without ball-joints (group B). The mean follow-up was 2.9 years. We retrospectively evaluated the operative time for fracture reduction with the external fixator, pain and range of motion of the knee and ankle joints, time to union, rate of malunion, reoperations and revisions of the external fixators, and complications. RESULTS: The time for fracture reduction was statistically higher in group B; the rate of union was statistically higher in group B; the rate of nonunion was statistically higher in group A; the mean time to union was statistically higher in group A; the rate of reoperations was statistically higher in group A; and the rate of revision of the external fixator was statistically higher in group A. Pain, range of motion of the knee and ankle joints, rates of delayed union, malunion and complications were similar. CONCLUSION: Although modular external fixators are associated with faster intraoperative fracture reduction with the external fixator, single external fixators are associated with significantly better rates of union and reoperations; the rates of delayed union, malunion and complications are similar.

Sagittal alignment of the cervical spine after neck injury.

The normal sagittal alignment of the cervical spine is lordotic and is affected by the posture of the head and neck. The question of whether loss of cervical lordosis is the result of muscle spasm after injury or a normal variation, and the clinical significance of such changes in sagittal profile of the cervical spine has been an issue of several studies. The purpose of this paper is to study the incidence of normal cervical lordosis and its changes after neck injury compared to the healthy population. We studied the lateral radiographs of the cervical spine of 60 patients with neck injury compared to 100 patients without a neck injury. Lateral radiographs were obtained in the standing or sitting position, and the curvature of the cervical spine was measured using the angle formed between the inferior end plates of the C2 and C7 vertebrae. In the patients without neck injury, lordotic and straight cervical spine sagittal alignment was observed in 36.5% each, double curvature in 17%, and kyphotic in 10%. In the patients with neck injury, lordotic sagittal alignment was observed in 36%, straight in 34%, double curvature in 26% and kyphotic in 4%. No significant difference between the two groups regarding all types of sagittal alignment of the cervical spine was found (p > 0.100). The alterations in normal cervical lordosis in patients with neck injury must be considered coincidental. These alterations should not be associated with muscle spasm caused by neck pain.

Surgical outcome of scaphoid nonunions in heavy manual workers.

The management of scaphoid nonunion in heavy manual workers is challenging. Symptoms appear earlier and manual labor-related stress at the operated nonunion site may worsen the postoperative outcome. This study involved 16 heavy manual workers with scaphoid nonunion (11 cases involving the dominant hand) treated by internal fixation and autologous bone grafting. The nonunion was in 12 patients in the waist, in 3 patients in the proximal, and in 1 patient in the distal pole of the scaphoid. Clinical and radiographic evaluation of union was done according to the criteria of Bynum et al. and Fernandez and Eggli. Pain, wrist motion, and grip strength were evaluated and compared to the contralateral side. At a mean follow-up of 24 months (range, 10 months to 6 years), the mean range of motion and the grip strength compared to the contralateral hand were 95% and 91%, respectively. Overall hand function was excellent in 13 patients, good in 2 patients, and fair in 1 patient. All except one patient were pain free and returned to their work without or with minimal complaints at an average of 3.4 months (range, 2-6 months), postoperatively. In 15 patients, scaphoid nonunions healed at a mean time of 64 days. One patient had a reoperation, and union was observed at 90 days after the second operation. In all patients, the radiolunate angle was restored to normal. One patient developed complex regional pain syndrome that resolved completely after 2 months with adequate intensive physical therapy. Clinical symptoms of scaphoid nonunions are more severe and appear earlier in heavy manual workers; in this group of patients, surgical treatment is necessary. The double-threaded screw provides adequate stabilization for union. Autologous cancellous bone graft, because of its plasticity and malleability to exactly fill the scaphoid defect, is recommended.

External fixation as a primary and definitive treatment for tibial diaphyseal fractures.

The aim of this study was to evaluate the effectiveness of unilateral external fixator as primary and definitive treatment for open tibial fractures, fractures with severe soft tissues injuries, threatened compartment syndrome, and in multiply injured patients. Two hundred and twenty-three tibial shaft fractures (212 patients) were treated. In open fractures, union was achieved in 25 weeks, while in closed in 21. There were 18 nonunions, 21 delayed unions, 4 malunions, 58 pin infections and 3 osteomyelitis. A reoperation was performed in 42 patients. Fat embolism was diagnosed in three patients, pulmonary embolism in five and deep venous thrombosis in 14. The external fixator was definitive treatment in 87.27%. Unilateral external fixators can be used as primary and definitive treatment for complicated tibia shaft fractures. Re-operation or change of the method must be performed only when there is a delay in callus formation.
