The induced membrane technique is used for bone reconstruction. It is based on the osteoinductive properties of a membrane induced by the insertion of a PMMA cement spacer. We will describe a simple, cost-effective method in which the body of a syringe is used to facilitate the cement introduction, allow insertion of a regular spacer, contain the cement volume in the extension of the diaphysis and protect the underlying tissues from the exothermic reaction during PMMA polymerisation.

BACKGROUND: Staged revision for periprosthetic infection of the hip is an accepted and widely used technique by many surgeons. However, single-stage exchange of the hip prosthesis remains an attractive option to others because of the advantages of reduced morbidity, shorter treatment time and hospital stay in addition to the reduced cost of treatment. HYPOTHESIS: Single-stage revision for periprosthetic hip infection can achieve excellent results if a specific protocol for patients' selection and management is followed...

Cement leakage is a serious adverse event potentially occurring during vertebroplasty. Pre-operative in-silico planning of the cement filling process can help reducing complication rates related to leakage. This requires a better understanding of the cement flow along the whole injection path. Therefore, the aim of the present study was to analyze bone cement flow behavior by stepwise injections through medical cannulas. Sixteen cannulas were assigned to four groups for stepwise injection of differently colored cement portions of 1ml volume...

BACKGROUND: Compared with total shoulder arthroplasty (TSA), total shoulder surface replacement (TSSR) may offer the advantage of preservation of bone stock and shorter surgical time, possibly at the expense of glenoid component positioning and increasing lateral glenohumeral offset. We hypothesized that in patients treated for osteoarthritis with a sufficient rotator cuff, TSA and TSSR patients have comparable functional outcome, glenoid component version, and lateral glenohumeral offset...

INTRODUCTION: Proximal plate fixation in periprosthetic femur fractures can be improved by plate anchorage in the greater trochanter (lateral tension band principle) or bicortical locking screw placement beside the prosthesis stem in an embracement configuration. Both concepts were compared in a biomechanical test using a femoral hook plate (hook) or a locking attachment plate (LAP). METHODS: After bone mineral density (BMD) measurement in the greater trochanter, six pairs of fresh frozen human femora were assigned to two groups and instrumented with cemented hip endoprostheses...

INTRODUCTION: Prevalence of giant cell tumor (GCT) at atypical locations like bones of the feet are rare, seen in <1% of cases. GCT may have aggressive features, including cortical expansion or destruction with a soft-tissue component. Difficult diagnosis most often followed with complicated management and high recurrence rate remains a challenge that is rarely reported. PRESENTATION OF CASE: We presented a case of forty-six-year-old male patient with giant cell tumor of the right calcaneus Campanacci 3 with secondary aneurysmal bone cyst (ABC)...

Immune responses are vital for bone regeneration and play an essential role in the fate of biomaterials after implantation. As a kind of plastic cell, macrophages are central regulators of the immune response during the infection and wound healing process including osteogenesis and angiogenesis. Magnesium-calcium phosphate cement (MCPC) has been reported as a promising candidate for bone repair with promoted osteogenesis both in vitro and in vivo. However, relatively little is known about the effects of MCPC on immune response and the following outcome...

INTRODUCTION: No evidence-based guidelines are available to determine the appropriate stem length, and whether or not to cement stems in revision total knee arthroplasty (TKA). Therefore, the objective of this study was to compare stresses and relative movement of cemented and uncemented stems of different lengths using a finite element analysis. MATERIALS AND METHODS: A finite element model was created for a synthetic tibia. Two stem lengths (95 and 160 mm) and two types of fixation (cemented or press fit) of a hinged TKA were examined...

Type 2 diabetes mellitus impairs osteogenesis in bone marrow stromal cells (BMSCs). Bone morphogenetic protein 2 (BMP2) has been extensively applied for bone defect restoration and has been shown to activate the Wnt signaling pathway. The objective of this study was to investigate the effects of BMP2 on the cell proliferation and osteogenesis of type 2 diabetic BMSCs in rats and explore whether BMP2 induced osteogenesis via the stimulation of Wnt signaling pathway. The cell experiments were divided into DM (diabetic BMSCs), BMP25 (induced with 25ng/ml BMP2), BMP100 (induced with 100ng/ml BMP2) and BMP25 +XAV groups...

As a treatment for painful vertebral compression fractures (VCFs), vertebral perforation does not require bone cement infusion. Here, we retrospectively assessed the long-term therapeutic effects of vertebroplasty in a comparison with those of vertebral perforation. The subjects were 64 patients who underwent percutaneous vertebroplasty (PVP group) and 67 patients who underwent vertebral perforation (Perforation group) between 2006 and 2011 at Takeda general hospital. We compared the analgesic effects of the treatments and the incidences of new VCFs between the groups at 15 months postsurgery...

AIMS: Periprosthetic fracture (PF) after primary total hip arthroplasty (THA) is an uncommon but potentially devastating complication. This study aims to investigate the influence of cemented stem designs on the risk of needing a revision for a PF. PATIENTS AND METHODS: We analysed data on 257 202 primary THAs with cemented stems and 390 linked first revisions for PF recorded in the National Joint Registry (NJR) of England, Wales and Northern Ireland to determine if a cemented femoral stem brand was associated with the risk of having revision for a PF after primary THA...

AIMS: The widely used and well-proven Palacos R (a.k.a. Refobacin Palacos R) bone cement is no longer commercially available and was superseded by Refobacin bone cement R and Palacos R + G in 2005. However, the performance of these newly introduced bone cements have not been tested in a phased evidence-based manner, including roentgen stereophotogrammetric analysis (RSA). PATIENTS AND METHODS: In this blinded, randomised, clinical RSA study, the migration of the Stanmore femoral component was compared between Refobacin bone cement R and Palacos R + G in 62 consecutive total hip arthroplasties...

INTRODUCTION: Total hip replacement is a successful procedure with long survival records compared to other joint arthroplasties. Cemented implants have been available for many years, however the complications associated with loosening and, ultimately, failure over time has led to the development of cementless stems and implants.The ideal prosthesis should recreate a biomechanically normal hip joint, allow pain-free function and last the patient's life span without requiring revision. Optimal results with uncemented femoral stems rely on obtaining initial stability, osseointegration, biological fixation, and uniform stress transfer to the proximal bone...

BACKGROUND: The strength of the cement-bone interface in tibial component fixation depends on the morphology of the cement mantle. The purpose of this study was to identify thresholds of cement morphology parameters to maximize fixation strength using a minimum amount of cement. METHODS: Twenty-three cadaveric tibiae were analyzed that had been implanted with tibial trays in previous studies and for which the pull-out strength of the tray had been measured. Specimens were separated into a group failing at the cement-bone interface (INTERFACE) and one failing in the bulk bone (BULK)...
