Pathogen identification in 84 Patients with post-traumatic osteomyelitis after limb fractures.

Ann Palliat Med 2020 03 17;9(2):451-458. Epub 2020 Mar 17.

Department of Orthopedics, Affiliated Hospital of Zunyi Medical University, Zunyi 563000, China; Joint Orthopaedic Research Center of Zunyi Medical University & University of Rochester Medical Center, Zunyi 563000, China.

Background: Chronic osteomyelitis is a serious complication of orthopedic trauma. Residual bacteria after incomplete debridement and/or bacterial colonization, bacterial biofilm formation, and generation of antibiotic-resistant bacterial strains in the microtubule system of compact bones due to irrational use of antibiotics often make the condition more prolonged, recurrent, and refractory. The passive immunotherapy targeting the protein components of bacteria has become an area of intense research interest, for which identifying the bacterial isolates in different areas at different time points remains a key step.

Fracture status in middle-aged individuals with early CKD: cross-sectional analysis of the CARTaGENE survey.

Osteoporos Int 2019 Apr 22;30(4):787-795. Epub 2019 Feb 22.

CHU de Québec Research Center, L'Hôtel-Dieu-de-Québec Hospital, Endocrinology and Nephrology Axis, Faculty and Department of Medicine, Université Laval, 10 McMahon, Quebec City, Quebec, G1R 2J6, Canada.

Whether early chronic kidney disease (CKD) is associated with fracture in middle-aged adults is unclear. In a cross-sectional analysis of the CARTaGENE survey, we observed that early CKD was not associated with increased fracture, did not modify the association between calcaneal QUS and fracture, but modified the association between clinical, pharmacological parameters and fracture.

Introduction: The association between advanced CKD and increased fracture risk is well described. Read More

Distal femur periprosthetic fracture is a potentially catastrophic complication following TKA and existing data document substantial distal femur bone mineral density (BMD) loss following TKA. However, distal femur BMD is virtually never measured clinically as no consensus approach exists. Read More

Patella incarceration with associated patella fracture: a rare case of a paediatric patient with no associated femoral fracture.

BMJ Case Rep 2018 Sep 14;2018. Epub 2018 Sep 14.

Trauma and Orthopaedic Department, West Hertfordshire Hospitals NHS Trust, Watford, UK.

We describe the case of a 15-year-old girl who presented to the Accident and Emergency Department with right knee pain and a tense effusion following a twist and fall directly onto her right knee. An MRI scan demonstrated that she had an incarcerated dislocated patella with an associated patella avulsion fracture. This required open reduction. Read More

Patellofemoral design enhancements reduce long-term complications of postero-stabilized total knee arthroplasty.

Knee Surg Sports Traumatol Arthrosc 2019 Apr 10;27(4):1241-1250. Epub 2018 Sep 10.

Université de Lille Nord de France, Lille, France.

Purpose: Few studies investigated whether trochlear and patellar design enhancements improve long-term outcomes of total knee arthroplasty (TKA). This study aimed to compare the long-term survival and complication rates of two consecutive generations of the same TKA system with identical tibiofemoral geometry, but different patellofemoral designs.

Methods: The authors retrieved the records of 93 patients (104 knees) operated with the HLS II system and 116 patients (122 knees) operated with HLS Evolution system. Read More

Increased Patellar Fracture Rate in Total Knee Arthroplasty With Preoperative Varus Greater Than 15°: A Case-Control Study.

J Arthroplasty 2018 12 7;33(12):3685-3693. Epub 2018 Aug 7.

Orthopedic Surgery Department, Croix-Rousse Hospital, Lyon, France.

Background: Management of severe varus deformity requires soft tissue balancing for implantation of low-constraint knee prosthesis. Patellar complications have been rarely studied in this specific group. Our hypothesis was that severe genu varum (>15°) would increase the rate of patellar complications. Read More

Imaging Following Fractures of and Around the Knee.

Semin Musculoskelet Radiol 2018 Sep 22;22(4):457-463. Epub 2018 Aug 22.

Department of Trauma and Orthopedic Surgery, Medical University of Vienna, Vienna, Austria.

Related to fractures of and around the knee, inappropriate technical factors related to the surgery, severe comminution of the fracture, early overly arduous rehabilitation of the patient, and patient-related noncompliances may have the potential for the risk of inadequate fixation and other complications. Loss of fixation, malunion/nonunion, infection, arthritis, arthrofibrosis, and symptomatic hardware are among postsurgical complications that may necessitate further reconstructive techniques. In this review, complications that may be encountered in the postsurgical period of fractures involving the patella, supracondylar femur, and tibial plateau are described. Read More

Treatment of displaced transverse fractures of the patella: modified tension band wiring technique with or without augmented circumferential cerclage wire fixation.

BMC Musculoskelet Disord 2018 May 24;19(1):167. Epub 2018 May 24.

Chang Gung University College of Medicine, Taoyuan, Taiwan.

Background: Displaced transverse fractures of the body of the patella are usually associated with disruption of extensor mechanism and should be fixed surgically. The most common method is a tension band wiring (TBW) technique. Some surgeons concurrently employ an augmented circumferential cerclage wiring (ACCW) technique to help fracture stabilization and aid in fracture healing; however, its role and effect on the treatment outcomes is unclear.

Department of Orthopaedic Surgery, Baylor College of Medicine, Houston, TX, USA - Division of Orthopaedic Surgery, Texas Children's Hospital, Houston, TX, USA.

Avulsion fractures of the inferior pole of the patella and proximal tibial apophysis are independently rare injuries. They occur in children due to the relative weakness of the apophyseal cartilage compared to the ligaments and tendons. The combination of these two fractures, is exceedingly rare, with only a few previously described cases in the literature. Read More
