Dedifferentiated chondrosarcoma is a rare malignancy with reported 5-year overall survival rates ranging from 7% to 24%. The purpose of this investigation determine the dedifferentiated in modern patient series and how it impacted by demographics, tumor characteristics, surgical treatment factors.This retrospective review Surveillance, Epidemiology, End Results (SEER) database 2001 2011. Kaplan Meier analyses were used for disease-specific survival. Univariable multivariable cox regression...

The use of bone-anchored osseointegration implants for amputation reconstruction continues to expand throughout the world. Benefits are thought include elimination socket-related problems and improved control proprioception prosthetic limb. Reported outcomes have been positive, but skepticism remains with regard risk infection implant failure. Further results from early adopters therefore needed prior widespread acceptance regulatory approval.A retrospective review first 31 consecutive...

The aim of this study is to evaluate the outcomes acute correction large varus and valgus deformities with simultaneous distal femoral tibial osteotomies. Acute coronal plane complex if done incorrectly, can lead problems like non-union, soft tissue problems, joint line obliquity. Radiographic, clinical, patient-reported are analysed through a retrospective series 21 extremities in 18 consecutive patients coexisting who underwent concurrent proximal osteotomies internal fixation. mean...

Osseointegrated limb surgery for amputees is becoming increasingly common due to its advantages over traditional socket prostheses. Institutions worldwide are developing services offer this option suitable patients and promoting these online. This study aims assess the quality readability of online information provided. The three most popular search engines using English language were searched, first 40 websites from each included. All included assessed reading Flesch-Kincaid Grade Level...

Background Osseointegrated (OI) prostheses are a novel alternative solution for patients with lower-limb amputations. Plastic surgeons becoming increasingly involved in providing concurrent thigh lifts (CTLs) to reduce soft tissue redundancy around the implant. Because of limited mobility, many present higher body mass indexes (BMIs) and may benefit from CTL. This study aimed evaluate outcomes obese OI who underwent CTL compared those did not. Additionally, we compare normal BMIs without...

Background: Osseointegration provides a direct prosthesis interface for lower-limb amputees, many of whom are poor candidates traditional socket-suspended prostheses. These skeletally anchored implants eliminate the skin-prosthesis interface, reducing complications such as soft-tissue breakdown, ulceration, and pain 1 . Soft-tissue contouring management peripheral nerves essential aspects osseointegrated implantation surgery both transfemoral transtibial amputees. techniques protect...

Press-fit transfemoral osseointegration is the technique of inserting an intramedullary metal implant into residual femur amputee; passed transcutaneously to attach a standard prosthesis that includes knee, tibia, ankle, and foot. This allows be skeletally anchored, eliminating socket-related problems such as tissue compression can provoke neurogenic pain, skin abrasion, fitting resulting from limb size fluctuation1. Amputees with osseointegrated prostheses typically wear their more...

Lower-limb osseointegrated prostheses are a novel alternative to traditional socket-suspended prostheses, which often associated with poor fit, soft tissue damage, and pain. Osseointegration eliminates the socket-skin interface allows for weight-bearing directly on skeletal system. However, these can also be complicated by postoperative issues that negatively impact mobility quality of life. Little is known about incidence or risk factors complications as few centers currently perform...

Abstract Purpose of Review To review the topic osseointegration amputation reconstruction, which inserts a transcutaneous metal implant into remaining intramedullary bone person with an to facilitate direct bone-anchored connection external prosthesis, eliminating molded socket interface. Recent Findings Evidence continues build that patients function better and have higher quality life implants compared traditional prosthetics. The indications for are expanding additional patient...

Benign bone tumors and tumor-like lesions are frequently diagnosed in children adolescents. The immature skeleton is at risk for growth disturbances deformity because of the effects on normal architecture physis. development, manifestation, severity limb length inequality differs between various pathologies. Distraction osteogenesis, osteotomy, guided key tools treatment using a combination external internal fixation devices.

Metastatic disease involving the femoral head and neck is often treated with a hemiarthroplasty or total hip arthroplasty (THA) to prevent pathologic fracture but there are no outcome studies demonstrating superiority of one option over other.This investigation was designed as survey current members Musculoskeletal Tumor Society (MSTS). The contained seven clinical vignettes identical imaging lesion neck. primary measured decision treat THA. Secondary outcomes included method fixation...

Introduction: The most common complication following transcutaneous osseointegration for amputees is infection. Although an obvious source of contamination the permanent stoma, operative site at time implantation may be additional source. This study investigates impact unexpected positive intraoperative cultures (UPIC) on postoperative Methods: Charts were reviewed 8 patients with UPIC and 22 negative (NIC) who had least 1 year post-osseointegration follow-up. All 24 h routine antibiotic...

Background: Transtibial amputation (TTA) reconstruction via press-fit osseointegration permits direct skeletal connection between a patient’s residual limb and the prosthetic leg. Osseointegration has predominantly been utilized in transfemoral (TFA), resulting overwhelmingly positive functional quality-of-life improvements compared with traditional socket prostheses 1–3 . The adoption of this technology slower TTA, likely because patients undergoing TTA have superior mobility those TFA,...

Background: The lateral opening wedge distal femoral osteotomy (DFO) is an effective treatment for genu valgum to improve mechanical alignment, decrease compartment loads, and the risk of knee osteoarthritis. Multiple studies have utilized outcome scores assessing functional changes related pain joint stability, with a focus solely on outcomes. Questions/purposes: primary aim this study was evaluate patient-reported measures (PROMs) that assessed function, pain, patient’s perception body...

Purpose Osseointegration (OI) is a novel alternative to traditional socket-suspended prostheses for lower-limb amputees, eliminating the socket-skin interface and allowing weight bearing directly on skeletal system. However, stoma through which implant attaches external prosthesis creates an ingress route bacteria, infection rates as high 66% have been reported. The aims of this study are classify management long-term outcomes in patient population maximize salvage. Methods An institutional...

Case: This report discusses 2 successful cases of traumatic transulnar amputees who underwent osseointegration implantation. After surgery, a myoelectric prosthetic equipped with Coapt (Chicago, IL) recognition software was attached directly to the implant. Patients training pattern learn control multiarticulating hand and wrist. Both implants osseointegrated without signs loosening at most recent follow-up 18 months years, respectively. Prosthetic gradually improved allow activities daily...

Abstract Nearly half of orthopaedic trauma patients are intoxicated at the time injury, and excess alcohol consumption increases risk for fracture nonunion. Previous studies show disrupts associated Wnt signaling required normal bone repair. Intermittent parathyroid hormone (PTH) promotes growth through canonical signaling, however, no have investigated effect PTH on alcohol‐inhibited Male C57BL/6 mice received two‐3 day binges separated by 4 days before receiving a mid‐shaft tibia fracture....
