Highlights Glomus tumor is a rare small benign perivascular tumor, which develops from the glomus body located in the reticular dermis. The pain caused by glomus tumor could be easily mistaken to lower extremity pain whether it is radiating, sciatic, or just a localized one. A localized thermoregulator subcutaneous tumor could generate paroxysmal pain and sensitivity to pressure which is feigned as chronic radiating pain. A thorough examination is the key to a proper diagnosis of uncommon locations of the tumor.

Background: Cuttlefish bone Xenograft, calcium phosphate (CaP)-based biomaterial graft, offers an alternative and has been accepted for osteoconductive and probable osteo-inductive attributes. This study aims to compare the bone healing potential between the bovine-derived (BHA) and cuttlefish bone-derived (CHA).Materials and Methods: The study compared osteoblast cell proliferation of 27 New Zealand rabbits in 2.5 mm bone defect made in the femoral bone. The samples were divided into three groups, which were control, BHA and CHA group. The chemical and physical characteristics of BHA and CHA were determined for the content of hydroxyapatite by FourierTransform Infrared Spectroscopy (FTIR) and X-Ray Diffraction (XRD), then tested by Scanning Electron Microscopy (SEM) to evaluate the porosity. In the end of the second week, histopathologic and immunohistochemistry examinations were performed to evaluate the amount of osteoblast and osteocalcin expression.Results: The FTIR, XRD and SEM analysis showed both BHA and CHA samples were hydroxyapatite according to Joint Committee on Powder Diffraction Standards (JCPDS). The CHA was significantly higher (297.22±19.772) compared to BHA (258.22±30.926) and control (131.67±34.213). Osteocalcin expression in CHA (7.82±2.230) compared to BHA (6.09±3.724) and control (4.07±3.606), was not significant (p>0.05). Conclusion: CHA group has the highest osteoblast cell proliferation and osteocalcin expression, meaning has a good potential as future source of bone graft.Keywords: cuttlefish bone, bovine, bone graft, osteoblast cell

Kirschner wire migration is a notorious incident in orthopedic surgery. Efforts to avoid it was carried out by several standard procedures, including bending the wire and reporting the cases all around the world in many journals. Nevertheless, the incident still happens, and some include symptoms that amazed doctors as to how the wire travelled. We reported a migration of forgotten wire to contra lateral region presented as corpus alienum of the lung in a 34-year-old woman after distal clavicular fracture surgery three years previously. We also reported a migrating wire fragment after a fall accident in sport activity of a 28-year-old male; which travelled from clavicular region to cervical 6–7 region in 4 days. Both cases were successfully managed without extravagant surgery or serious damage, helped by meticulous history taking, physical examination, precise imaging, and prompt management. These cases render lessons and discussion for further understanding of the wire migration and the exact protocol in handling K-wire patient. Highlights:

Background<br />Elbow deformity in children due to neglected proper fracture management is a devastating condition. The stiffness and pain complicated the function in daily activity. Successful management of neglected elbow dislocation is a challenging problem for orthopedic surgeons. In this study, we aimed to evaluate results of open reduction for neglected elbow dislocation in children.<br /><br />Case Description<br />This is a case series of 13-14 years old neglected elbow dislocations, for up to 15 months. Open reduction after external distractor and followed by intensive rehabilitation was implemented. Clinical and functional outcome were evaluated within 4-7 years. Initial average elbow flexion was 53,3°, extension was 0°, arc of flexion was 53,3°, arc of pronation-supination was 150° and Mayo Elbow Performance Index (MEPI) was 80. Clinical and functional outcome were evaluated within 4-7 years. At follow-up after open reduction, the improvement in whole range of movement was significant. Average elbow flexion was 118,3°, extension was 36,67°, arc of flexion was 81,67°, arc of pronation-supination was 133°. The average improvement of flexion was 65°, arc of flexion was 31,67°, and arc of pronation-supination was 8,3°. The average loss of flexion was 15,5%, arc of flexion was 44,2%, and arc of pronation-supination was 10,7% compared with uninjured side. The average Mayo Elbow Performance Index (MEPI) was 96,67; all with excellent results.<br /><br />Conclusion<br />Planned and well execution open reduction in pediatric neglected elbow dislocation may bring back the painless movement within normal daily function.
