We prospectively compared the safety and effectiveness of mini-incision (group A) and a limited open technique (group B) for carpal tunnel release (CTR) in 185 consecutive patients operated between November 1999 and May 2001, with a 5-year minimum follow-up. Patients in Group A had a minimally invasive approach (<2 cm incision), performed using the KnifeLight (Stryker, Kalamazoo, Michigan) instrument. Patients in Group B had a limited longitudinal incision (3-4 cm). Patient status was evaluated with an Italian modified version of the Boston Carpal Tunnel questionnaire, administered preoperatively and at 19, 30, and ...

Percutaneous CT-guided vertebroplasty in the management of osteoporotic fractures and dorsolumbar metastases.email this articleEmail this article to a colleague. save this article to My ClippingsSave this article to My Clippings. discuss this articleDiscuss or comment on this article.
Percutaneous vertebroplasty (PVP) is a minimally invasive, image-guided procedure consisting of an injection of acrylic cement into a vertebral body to reinforce the compressed segment and achieve pain relief. The use of PVP is a minimally invasive option in the treatment of osteoporotic or metastatic vertebral collapses. Our personal experience, using a CT-guided technique, confirms the efficacy and safety of PVP with a lower risk for complications compared with conventional fluoroscopic approaches because of a precise placement of the instruments in the vertebral body and an early detection of small cement leakages. ...

The concept of minimally invasive total knee arthroplasty surgery evolved to reduce quadriceps muscle strength loss and improve clinical outcome following total knee replacement. We performed a systematic review of the published literature on Minimally Invasive Total Knee Arthroplasty (MITKA) and analyzed the reported surgical outcomes. Twenty-eight studies published from January 2003 to June 2008 that met the inclusion criteria were evaluated using the modified Coleman Methodology Score (CMS). At a mean CMS of 60, most studies reporting on outcome of MITKA are of moderate scientific quality. Patients undergoing MITKA ...

Minimally invasive osteosynthesis of distal tibial fractures using locking plates.email this articleEmail this article to a colleague. save this article to My ClippingsSave this article to My Clippings. discuss this articleDiscuss or comment on this article.
The management of distal tibia fractures can be challenging because of the scarcity of soft tissue, their subcutaneous nature, and poor vascularity. Classic open reduction and internal plate fixation require extensive soft tissue dissection and periosteal stripping, with high rates of complications. Minimally invasive plating techniques reduce iatrogenic soft tissue injury and damage to bone vascularity and preserve the osteogenic fracture hematoma. Locking plates (LPs) have the biomechanical properties of internal and external fixators, with superior holding power because of fixed angular stability through the head of...

Tendinopathy arises from a failed tendon healing process. Current non-invasive therapeutic alternatives are anti-inflammatory in nature, and outcomes are unpredictable. The benefit of invasive alternatives resides in the induction of the healing response. A new technology that uses non-invasive monopolar capacitive coupled radiofrequency has demonstrated the ability to raise temperatures in tendons and ligaments above 50 degrees C, the threshold for collagen modulation, tissue shrinkage and recruitment of macrophages, fibroblasts, and heat shock protein factors, without damaging the overlying structures, resulting in a...

The anterior approach is a safe, reliable, and feasible technique for total hip arthroplasty, permitting optimal soft tissue preservation. Since Hueter first described this interval, many surgeons have approached the hip anteriorly to perform a myriad of surgical procedures. The anterior approach allows optimal muscle preservation, and it is a truly internervous approach to the hip. An understanding of the evolution of the anterior approach to the hip will help the orthopedic community understand these advantages and why so many have used this approach in the treatment of hip pathology and for the implantation total hi...

Among 338 patients on statins, 15 (4.4%) developed osteonecrosis, versus 180 of 2,543 (7%) patients who were not on statins. Osteonecrosis-free survival was similar in patients with and without statin exposure. ...

Respherical contour with medial collapsed femoral head necrosis after high-degree posterior rotational osteotomy in young patients with extensive necrosis.email this articleEmail this article to a colleague. save this article to My ClippingsSave this article to My Clippings. discuss this articleDiscuss or comment on this article.
In this study, the authors evaluated the effectiveness of high-degree posterior rotation in terms of regaining the spherical contour of severely collapsed necrotic femoral head that was moved medially. They also investigated whether or not subchondral fracture disappeared on the medial femoral head on postoperative anteroposterior radiographs as a result of remodeling after this procedure.

Outcome of uncemented primary femoral stems for treatment of femoral head osteonecrosis.email this articleEmail this article to a colleague. save this article to My ClippingsSave this article to My Clippings. discuss this articleDiscuss or comment on this article.
This study examined the outcome of the femoral stem of four generations of an uncemented, proximally porous-coated, chrome-cobalt total hip prosthesis. There were 158 cases in 141 osteonecrosis patients (74 men, 67 women) who had a mean age of 46 years (range, 17-83 years). The mean follow-up was 103 months (range, 20-235 months). The femoral components of 144 cases were not revised and had a mean Harris hip score of 84 (+/-15) at final follow-up. Of the 14 revisions (8.9%), the primary reasons for revision were loosening or significant osteolysis. There were one infection and one chronic dislocation. Proximally porous-coa...

Total hip arthroplasty after failed treatment for osteonecrosis of the femoral head.email this articleEmail this article to a colleague. save this article to My ClippingsSave this article to My Clippings. discuss this articleDiscuss or comment on this article.
This article presents results for total hip arthroplasty after failed transtrochanteric rotational osteotomy according to Sugioka and after failed bone impaction grafting, both initially performed for osteonecrosis of the femoral head. After a minimal follow-up of 2 years, 33 hips were studied. In total hip arthroplasty after failed osteotomy, when compared with total hip arthroplasty after failed bone impaction grafting, clinical and radiologic outcome was less favorable, more complications were observed, and there was a higher revision rate for a technically more demanding procedure.

Current literature: an educational tool to study osteonecrosis for the Orthopaedic In-Training Examination?email this articleEmail this article to a colleague. save this article to My ClippingsSave this article to My Clippings. discuss this articleDiscuss or comment on this article.
The Orthopaedic In-Training Examination (OITE) is used to evaluate the knowledge of residents and focuses on relevant information supported by current scientific literature. The purpose of this study was to assess the relevance of current literature as a study tool for the exam, especially for osteonecrosis-related material. A systematic review was conducted of the OITE and relevant journals to compare the proportion and characterization of questions and published studies related to osteonecrosis and other frequently tested subject areas over a 5-year period (2002 to 2006). This review suggests that the OITE and litera...

Diagnosis and staging of spine tumors.email this articleEmail this article to a colleague. save this article to My ClippingsSave this article to My Clippings. discuss this articleDiscuss or comment on this article.
Persistent axial pain with or without neurologic changes should prompt workup for a possible tumor of the spine. Metastatic disease is more predominant than primary tumors, but still needs adequate evaluation before any management. The various steps of evaluation, diagnosis, and staging are reviewed.

Total en bloc spondylectomy for spinal tumors: surgical techniques and related basic background.email this articleEmail this article to a colleague. save this article to My ClippingsSave this article to My Clippings. discuss this articleDiscuss or comment on this article.
The authors' group has developed a new surgical technique of spondylectomy (vertebrectomy) called "total en bloc spondylectomy" (TES). This technique is different from spondylectomy in that it involves en bloc removal of the lesion, that is, removal of the whole vertebra, body and lamina, as one compartment. The surgical technique of TES has been remarkably improved based on adequate knowledge and consideration of the surgical anatomy, physiology, and biomechanics of the spine and spinal cord. Review of the developmental process of this operation leads to recognition of the tips, pitfalls, and solutions. PMID: 1906...
