K-wiresare generally used in orthopedic fracture surgery. Pinning with metal wires is a reasonable option for proximal humeral fractures treatment. One 91-year-old man received multiple K-wire fixation for left proximal humeral fractures. Later in postoperative follow-up at the outpatient department, he illustrated symptoms of tenderness, swelling, coin-sized bullae formation and ecchymosis over left axillary region.K-wire migration was noted, which lead to brachial artery injury with traumatic pseudoaneurysmformation. The patient underwent emergent surgery wherepreviously placed K-pins were removed and then received revascularization surgery afterward. Functional shoulder brace was adopted for his postoperative immobilization of left shoulder and fracture site bony :union: was noted an year later. He lead independent activity of daily life as previously before the accident.
Previous documents had reported potentially dramatic complications related to wires migration and most of them were intra-thoracic migration cases. We present the uncommon case of brachial artery injury with traumatic pseudoaneurysm. While it may not be as detrimental injury as intra-thoracic migration of K-pins, brachial artery penetration could lead to more undetected clinical symptoms and result in irreversible damage. Orthopedic surgeons should consider related risks when using K-wire fixation over proximal humerus,especially in cases of elder patients with possible lowcompliance to immobilization and low bone quality. Most important of all, doctors must alert patients about the importance of returning for follow-up evaluation postoperatively,and for the removal of K-wires.

Supracondylar fractures of the humerus comprise the most common fracture in children. Two-thirds of children، who are hospitalized due to arm injury، are infected by Supracondylar fractures. The aim of this research is to investigate two treatment methods، «close reduction and external fixation with pin» and «open reduction and internal reduction in Supracondylar fractures. This clinical trial study was conducted in Ayatollah Kashani hospital، Sharekord، Iran in 2010. Ninety patients with suppracondilar fracture type III were selected and through Random Number Table allocated in two groups. The first group cured by close reduction and external fixation with pin through C-arm control and the second group were cured by open reduction and subcutaneous pin and internal fixation and then underwent surgery through posterior fixation. The patients، information including the duration of operation، radiography، wound infection، treatment cost، and the rate of movement area of elbow in the eighth week post operation were collected. The data were analyzed using chi-square and t-test tests. There was no significant difference between two groups in terms of age، gender، urban and rural place of residence، fracture side and arm fracture. After the first week of operation، 3 patients (6. 66%) operated by open reduction and one patient (2. 22%) operated by closed reduction were infected (P<0. 05). The mean of elbow movement 8wecks after operation was 118. 3±10. 9 in opened group and it was 131. 5±10. 5 in close group grade (p<0. 001). The mean of operation time and operation cost was significantly more in the open group than the close group (P<0. 001). Based on the results of this study، the frequency distribution of postoperative complications، cost، hospitalization duration in the close group was lower than the opened group and more effective in suppracondilar fracture treatment. This method was prescribed for treatment of humerus fractures.

Simultaneous anterior fracture-dislocation of the shoulder and fracture of the ipsilateral humeral shaft results from severe trauma and is very rare. In this report we present such an injury and its treatment. Case Report: A 48-year old man was brought to hospital after a motor bike accident with anterior dislocation of the shoulder and fracture of the ipsilateral humeral shaft and greater tuberosity.Both injuries were treated by open reduction and internal fixation By timely diagnosis of this rare and disabling injury, full treatment can be given. Thus, performing an accurate examination and obtaining the essential x-rays are mandatory.
