Allograft reconstruction is a valuable treatment option for patients with chronic extensor mechanism disruption after total knee arthroplasty. Here, an hourglass variant of the original partial allografttechnique is described. An hourglass-shaped patellar bone block is press-fit into the native patella. The graft is fixed to both the patella and the tibia then sutured with the knee fully extended. Outcomes of this technique were assessed in 5 patients after at least 24 months' follow-up. The mean knee and function Knee Society Score values were 77...

INTRODUCTION: Total elbow arthroplasty (TEA) is one option in distal humerus fracture in elderly osteoporotic patients. HYPOTHESIS: The study hypothesis was that, in patients aged 70 years or more,TEA provides functional results and ranges of motion compatible with everyday activity, with a complications rate equal to or lower than with internal fixation, and no loss of autonomy or cognitive impairment. MATERIALAND METHODS: In this retrospective study, 21 patients receiving TEA for distal humerus fracture were included...

INTRODUCTION: There is currently no consensus on how to treat patients with lower extremity trauma. Should amputation be performed early on to avoid complications or should the limb be saved at any price?The goal of this study was to show that early amputation is a viable treatment option in lower extremity trauma cases. MATERIAL AND METHODS: Twenty patients who underwent early amputation and 16 patients who underwent limb-salvage were included with a minimum follow-up of 1 year...

INTRODUCTION: The suprascapular nerve (SSN) can become compressedatits 2 scapularattachments: the suprascapular and the spinoglenoid notch. The objective of this study was to describe a new arthroscopicapproach for SSN neurolysis at the spinoglenoid notch. METHOD: 10 cadaver shoulderswereused. Two weredissected to simulate the "classical" arthroscopic approach and to help in the creation of a new "direct medial retrospinal" approach. Eight othershoulders were used to validatethis new approach, with control of the whole juxta-glenoidcourse of the SSN as criterion of success...

BACKGROUND: Catheter-delivered continuous interscaleneanesthesia has demonstrated improved pain control in randomized clinical trials.The purpose of this study is to determine whether the introduction of continuous catheteranesthesia was associated with a change in length of stay (LOS), readmission, rates of discharge home without home health or nursing services, or opioid administration. We hypothesized that the introduction of continuous catheter anesthesia would be associated with a decrease in LOS, readmission, non-home discharge, and opioid administration...

BACKGROUND: There is no universally accepted approachto the elbow for the fixation of coronoid process fractures.This study aims to introduce a novel anterior surgicalapproach for the fixation of the ulnar coronoid fracture, with minimal surgical dissection damage and excellent visualization for reduction and internal fixation. HYPOTHESIS: The anterior approach can facilitatesatisfactory outcomesfor coronoid process fractures. MATERIAL AND METHODS: From February 2010 to July 2014, 12 patients (8 males and 4 females; range 14-62 years; mean age 31 years) with a closed fracture of the coronoid process of the ulna were included in this study...

BACKGROUND: Tunnel positioning assessment is a major issue after anterior cruciate ligament (ACL) reconstruction surgery. Historically, it used plain X-ray and, more recently, CT with 3D reconstruction. MRI is a reliable method of assessing ACL graft integrity and postoperative complications. To our knowledge, there have been no studies of efficacy in tunnel positioning assessment. The aim of this study was to assess the efficacy of 3D MRI in assessing femoral and tibial tunnel positioning after ACL reconstruction...

INTRODUCTION: Coracoid bone graft transfer has become the gold standard in patients with recurrent anterior shoulder instability associated with bony defect. Several studies have shown that the main stabilizing component of this procedure is the sling effect by the conjoint tendon and the lower portion of subscapularis (SS). The purpose of this study was to determine whether a larger SS volume below the bone block was correlated to greater postoperative shoulder stability. MATERIALS AND METHODS: This prospective study included a cohort of patients who underwent open coracoid bone graft transfer for post-traumatic recurrent anterior shoulder instability...

BACKGROUND: Surgeon at primary total hip arthroplasty sometimes cannot achieve sufficient cementless acetabular press-fit fixation and must resort to other fixation methods. Despite a predominant use of cementless cups, this issue is not fully clarified, therefore we performed a large retrospective study to: (1) identify risk factors related to patient or implant or surgeon for unsuccessful intraoperative press-fit; (2) check for correlation between surgeons' volume of operated cases and the press-fit success rate...

INTRODUCTION: Reconstruction of large diaphyseal bone defect is complex and the complications rate is high. This study aimed to assess a simplified technique of segmental bone transport by monorail external fixator over an intramedullary nail. MATERIAL AND METHOD: A prospective study included 7 patients:2 femoral and 5 tibial defects.Mean age was 31 years (range, 16-61 years). Mean follow-up was 62 months (range, 46-84 months). Defects were post-traumatic, with a mean length of 7...

BACKGROUND: Although standard instrumentation is the procedure most frequently used to implant a total knee arthroplasty (TKA), high rates of malalignment of tibial component are reported using this technique. Anatomical landmarks for sagittal alignment have been little investigated and the best reference axis which parallels the mechanical axis is yet to be established. HYPOTHESIS: Mapping the anterior tibial profile (ATP) may allow the identification of segmental zones of the ATP parallel to the mechanical axis which can be use to align the extramedullary rod...

Adipose tissue is an abundant source of various cell types including not only adipocytes, but also progenitor and endothelial cells from thestroma. Interest in adipose tissue has surged since the identification in 2001 of adipose-derived stem cells (ADSCs) and of the stromal vascular fraction (SVF) obtained from adipose tissue by enzymatic digestion and centrifugation. SVF has been proven effective in ensuring tissue regeneration, thus improving tissue trophicityand vascularisation. These effects have generated strong interest among both physicians and surgeons, particularly in the field of hand surgery...

INTRODUCTION: Dislocation after total hip arthroplasty (THA) is a leading reason for surgical revision. The risk factors for dislocation are controversial, particularly those related to the patient and to the surgical procedure itself. The differences in opinion on the impact of these factors stem from the fact they are often evaluated using retrospective studies or in limited patient populations. This led us to carry out a prospective case-control study on a large population to determine: 1) the risk factors for dislocation after THA, 2) the features of these dislocations, and 3) the contribution of patient-related factors and surgery-related factors...

BACKGROUND: Proper reduction and stable fixation of articular fractures is essential for an early recovery and to avoid late complications. Arthroscopically assisted techniques for minimally invasive fixation have been introduced to reduce local morbidity and improve anatomic reduction of the fragments. However up to date no clear indications for surgery have been given. In addition, the precise rates of functional outcomes and complications are controversial. The hypothesis was the systematic analysis of the available literature would provide precise indications, outcomes and complications of arthroscopically assisted techniques for patellar fracture fixation...

BACKGROUND: Various factors contribute to instability of total hip arthroplasty (THA), with implant orientation being a major contributor. We performed a case-control study with computed tomography (CT) data to determine whether: 1) orientation contributes to THA instability and 2) a safer target zone for stability than Lewinnek's classic safe zone can be defined. MATERIAL AND METHODS: We included prospectively 363 cases of THA dislocation that occurred during the calendar 2013 year in 24 participating hospitals...
