To promote rapid bone healing, an adequate stable fixation implant with a percutaneous reduction instrument should be used for Vancouver type B1 or C fractures. The objective of this study was to describe radiographic and clinical outcomes of patients with periprosthetic fracture (PPF) around a stable femoral stem, treated with a distal femoral locking plate alone or with a cerclage cable. A total of 21 patients with PPF amenable to either a reverse distal femoral locking plate (LCP DF(®)) alone or with a cerclage cable, with a mean age of 75...

Large bone defect creates an urgent need for osteogenic biomaterials. However, bone nonunion and infection are choke points in the therapy of this disease. How to recruit the mesenchymal stem cells to defect sites and increase the cell viability are the critical processes. One effective method was the fabrication of biomimetic silk fibrin/selenium-doped hydroxyapatite (SF/HASe) material, which could create a niche for cell proliferation. So, the aim of the present study was to seek a facile route to prepare this biocomposites and investigate the osteogenic capability...

BACKGROUND: Bone SPECT can be used after a femur neck fracture to assess the circulation of the femoral head in the immediate postoperative period because the blood supply is one of the major factors affecting bone uptake of radiotracer on bone scintigraphy. The purpose of our present study was to investigate whether osteonecrosis of the femoral head (OFH) after internal fixation of femoral neck fracture could be predicted by early and late bone SPECT. METHODS: This retrospective cohort study enrolled 44 patients (33 women; mean age, 66...

If over-suppression of bone turnover explained the association between bisphosphonate use and atypical subtrochanteric femur fractures (AFF), this could be reversed with anabolic treatment such as teriparatide. We conducted a prospective, open label study in patients previously treated with bisphosphonates who sustained AFF, examining the response to 24 months treatment with teriparatide on bone mineral density (BMD), trabecular bone score (TBS), bone turnover markers (BTM) and fracture healing as well as quantitative histomorphometry...

AIMS: Free vascularised fibular grafting has been used for the treatment of large bony defects for more than 40 years. However, there is little information about the risk factors for failure and whether newer locking techniques of fixation improve the rates of union. The purpose of this study was to compare the rates of union of free fibular grafts fixed with locking and traditional techniques, and to quantify the risk factors for nonunion and failure. PATIENTS AND METHODS: A retrospective review involved 134 consecutive procedures over a period of 20 years...

REVIEW
Ahmadreza Afshar
Replacing an extruded segment of bone in an open fracture imposes a challenging decision concerning the best and safest patient management. There are numerous advantages to restoring the patient's own extruded bone segment to its original location, particularly when the bone segment is of structural importance. However, reimplantation of contaminated and avascular extruded bone segments can potentially result in serious infection or nonunion. There is no conclusive evidence regarding the best decontamination protocol for the safest use of the recovered bone segment as an autologous graft...

BACKGROUND: As the tibial bone defect increases in size, the problems in treatment also increase. The treatment may be problematic but different treatment approaches can be used. Among these approaches, distraction osteogenesis is a method an orthopedic surgeon with limited conditions can use although it has a longer treatment period. In our case series, we evaluated current treatment approaches. METHOD: Retrospective study based on patient records and radiographs...

The management of upper limb non-unions can be challenging and often with unpredictable outcomes. In this study we present our experience with the use of BMP-7 in the treatment of upper limb non-unions. Between 2004 and 2011 all consecutive patients who were treated with BMP-7 were followed up prospectively until fracture union. Fracture union was assessed with regular radiological and clinical assessment. At the final follow up clinical assessment included the short Disabilities of the Arm, Shoulder and Hand (DASH) score...

INTRODUCTION: Nonunion following closed treatment of humeral shaft fracture is estimated to be 5.5%. Many surgical techniques have been described to address humeral shaft nonunion including: open reduction, internal fixation (ORIF) with compression plating and bone graft, dual plating, cortical strut allograft and autograft, and adding biologic augmentation (BMP). The current standard of care includes ORIF with compression plating and bone grafting, but even this technique has an approximated 10% failure rate...

: Charcot fracture pattern (FP) and Charcot dislocation pattern (DP) are 2 distinct collapse patterns identified in Charcot neuroarthropathy of the foot and ankle. These patterns are believed to demonstrate relative differences in central bone mineral density (BMD), which has been theoretically extrapolated to describe local BMD. To assess variation in local bone composition of FP and DP patients, 10 patients, 5 DP and 5 FP were recruited. The patient's age, body mass index (BMI), radiographs, central BMD, local BMD, sRANKL (soluble receptor activator nuclear factor kappa-beta ligand), sRAGE (soluble receptors of advanced glycated end-products), and osteocalcin were measured to determined bone metabolic status and density...

A 13-year-old, right hand-dominant, otherwise healthy boy presented with left wrist pain 19 months after a nonmotorized scooter injury. Radiographs and magnetic resonance imaging at presentation demonstrated proximal pole scaphoid nonunion with avascular necrosis of the proximal fragment. Operative and nonsurgical treatment options were discussed and the family elected for an attempt at nonsurgical management. The patient was placed in a short-arm thumb spica cast, with a window for a bone stimulator, for 14 weeks...

BACKGROUND: Non-union of tibia is known to be a common complication after fracture both bones of leg treated conservatively. During the course of natural healing, fibula usually unites early as it had more soft tissue attachment and vascular supply. Due to early union of fibula and absence of axial force across the tibia, it undergoes non-union. CASE CHARACTERISTICS: Two cases, a 32-year-old male and 65-year-old female treated conservatively for fracture both bones of leg long years back, presented to us with mild calf pain on and off...

Accordion Maneuver is a strong "Bloodless Tool" in the Ilizarov technology, that helps to bring about healing of nonunion of fractures of long bones. A 50 years old male, a rare case of Pycnodysostosis, presented to us with recalcitrant nonunion of the fracture shaft of the femur after two failed surgical attempts, with a broken plate in the last attempt. We treated this very difficult nonunion by Ilizarov monofocal osteosynthesis with Accordion Maneuver that finally yielded union. This appears to be the only case report of treating such a case with Accordion Maneuver...

Nonunion of femoral shaft fracture is an uncommon complication after closed intramedullary nailing which often leading to nail breakage. Removal of the broken femoral nail with closed manner is a challenging procedure for orthopedic surgeons. The removal technique with the T-reamer is a closed method, which does not require either a nonunion site opening or knee exposing. We reported 3 cases of nonunion femoral shaft with broken slotted and non-slotted hollow nail which were successfully removed without any complication...
