Patterns of stress distribution at the proximal femur after implantation of a modular neck prosthesis. A biomechanical study.

Background: Modular total hip arthroplasty incorporating a double taper design is an evolution offering potential advantages compared to single head-neck taper or monolithic designs. Changes in femoral offset, neck length or femoral anteversion are expected to alter the strain distribution.

Methods: We therefore analyzed the strain patterns after usage of all types of necks of a modular neck prosthesis, implanted in composite femurs.

Bacterial wound contamination during simple and complex spinal procedures. A prospective clinical study.

Background Context: Spinal procedures have a potential of intraoperative contamination. C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) have been used to diagnose postoperative infections after spinal surgery. However, it has not been demonstrated if there is an association between surgical site contamination and clinical manifestation of postoperative infection based on inflammatory markers and patients' clinical course.

Computer-assisted three-dimensional correlation between the femoral neck-shaft angle and the optimal entry point for antegrade nailing.

Optimal entry point for antegrade femoral intramedullary nailing (IMN) remains controversial in the current medical literature. The definition of an ideal entry point for femoral IMN would implicate a tenseless introduction of the implant into the canal with anatomical alignment of the bone fragments. This study was undertaken in order to investigate possible existing relationships between the true 3D geometric parameters of the femur and the location of the optimum entry point.

Solitary tibial osteolytic lesion.

We report an unusual case of solitary osteolytic tibial metastasis from a primary endometrial cancer in a 62-year-old woman. The primary cancer was treated with total abdominal hysterectomy and bilateral salpingo-oophorectomy combined with postoperative external beam radiotherapy, while the tibial metastasis was treated with an above knee amputation. The rarity of the case lies on the fact that metastases distally to the elbow and knee are uncommon and endometrial cancer rarely gives distal bone metastases and particularly solitary to the extremities.

Combined radiotherapy and indomethacin for the prevention of heterotopic ossification after total hip arthroplasty.

Background And Purpose: :Heterotopic ossification (HO) is a frequent complication following total hip arthroplasty. The aim of this study was to evaluate the efficacy of combined radiotherapy and indomethacin as compared to indomethacin alone for the prevention of HO after hip arthroplasty.

Patients And Methods: 96 patients were prospectively enrolled to receive either a single dose of postoperative radiotherapy of 7.

Transtibial versus anteromedial portal of the femoral tunnel in ACL reconstruction: a cadaveric study.

The aim of this cadaveric study was to compare the transtibial versus the anteromedial portal with respect to the anatomic femoral positioning of the ACL attachment. Ten fresh frozen cadaveric knees were included in our study. A standard arthroscopy was performed and the normal ACL was partially cut through with arthroscopic scissors leaving a small footprint of 2 mm at the anatomical insertion area on the lateral femoral condyle.

Intrinsic haemangioma of the median nerve: report of a case and review of the literature.

Intrinsic haemangioma of the median nerve is an extremely rare tumor that represents a challenge to diagnose and treat. Only a few cases have been reported in the literature. We present a 10-year-old girl who was diagnosed having an intrinsic haemangioma of the median nerve and treated with total surgical resection of the tumor, under high magnification, using microneurolysis and without the need to resect and graft the median nerve.
