PURPOSE: Degenerative joint disease of the lumbar spine is a pervasive problem in healthcare; however, its aetiology and risk factors remain poorly defined. There have been recent attempts to correlate the anatomic parameters of facet angle and pelvic incidence with spine osteoarthritis, although data remains limited. The purpose of this experiment was to determine how age, gender, race, facet angle, tropism, and pelvic incidence correlate to facet joint osteoarthritis in the lumbar spine...

PURPOSE: Skeletal muscle injuries are commonly observed in sports and traumatology medicine. Previously, we demonstrated that transcutaneous application of carbon dioxide (CO2) to lower limbs increased the number of muscle mitochondria and promoted muscle endurance. Therefore, we aimed to investigate whether transcutaneous CO2 application could enhance recovery from muscle injury. METHODS: Tibialis anterior muscle damage was induced in 27 Sprague Dawley rats via intramuscular injection of bupivacaine...

BACKGROUND: The literature on ankle valgus development after procuring non-vascularised fibular grafts in children is still scanty. The non-vascularised fibular graft has distinction of fibular regeneration occurring at the donor site. MATERIAL AND METHODS: We retrospectively analysed the valgus deformities at the donor leg following harvest of non-vascularised fibular graft to determine the various contributing factors in growing children. All these patients had minimum two years post index procedure follow up...

Di Zhang, Xianda Gao, Jiang Jiang, Fanlong Kong, Yong Shen, Wenyuan Ding, Xiufang Hao, Huixian Cui
PURPOSE: Laminectomy with lateral mass screw fixation has been proven to be an effective method to treat the multilevel cervical degenerative myelopathy and severe cervical spondylosis. However, accurate and safe insertion of the lateral mass screw is technically demanding due to the individual variations of the anatomy of the lateral mass of the subaxial cervical spine. Misplaced lateral mass screw is not uncommon, and operation-related complications still beset the surgeons, which may impair the clinical outcomes...

INTRODUCTION: The dual-mobility cup (DMC) was introduced in 1979. Due to lack of referenced publications, this interesting and innovating concept was ignored during close to 20 years. However, 180 studies (level III or IV) have now been published. Evidence-based medicine is based on level I studies. Over the past three decades, the role of national registries developed with the intention of surveying orthopaedic implants. In 2012, we developed, registered, and implemented a specific database for contemporary DMC...

Over the last 40 years International Orthopaedics has published a series of articles on bone morphogenetic proteins (BMPs) covering topics from basic research to clinical applications. This includes also work submitted from the Laboratory for Mineralized Tissues of the School of Medicine University of Zagreb. Accordingly, we felt obliged to give a short summary of Dr. Urist's life and work as our gratitude to his discovery that demineralized bone matrix (DBM) activity induces bone when implanted ectopically into the muscle or under the skin due to bone inducing proteins, named BMPs...

BACKGROUND: Intra-operative sensing technology is an alternative to standard techniques in total knee arthroplasty (TKA) for determining balance by providing quantitative analysis of loads and point of contact throughout a range of motion. We used intra-operative sensing (VERASENSE-OrthoSensor, Inc.) to examine pie-crusting release of the medial collateral ligament in knees with varus deformity (study group) in comparison to a control group where balance was obtained using a classic release technique and assessed using laminar spreaders, spacer blocks, manual stress, and a ruler...

PURPOSE: We analysed hyaline cartilage of human knee and ankle joints for collagen and proteoglycan turnover in order to find differences in the metabolism and biochemical content of the extracellular matrix that could explain the higher prevalence of osteoarthritis (OA) in the knee joint, compared to the ankle joint. METHODS: Cartilage tissue from ankle and knee joints of OA patients were assessed for total collagen and proteoglycan content. For turnover, the aggrecan 846-epitope (CS 846), the type II collagen C-propeptide (CP2) and the collagenase-generated intrahelical cleavage neoepitope (C2C) were quantified...

INTRODUCTION: Osteoporotic vertebral fractures (OVF) can lead to late collapse which often causes kyphotic spinal deformity, persistent back pain, decreased lung capacity, increased fracture risk and increased mortality. The purpose of our study is to compare the efficacy and safety of vertebroplasty against conservative management of osteoporotic vertebral fractures without neurologic symptoms. MATERIAL AND METHODS: A total of 66 patients with recent OVF on MRI examination were included in the study...

PURPOSE: The primary objective of this study was to evaluate factors that influence the survival rate after digit replantation. METHODS: A total of 291 digits of 200 patients who received digital replantation after complete amputation from 1 January 2014 to 31 December 2015 were included in this study. Univariate and multivariate analysis were performed to evaluate the correlation between potential risk factors and the failure rate. Age, gender, smoking status, Tamai level of amputation, causes of injury and ischemia time were recorded before replantation...

PURPOSE: Diagnosing periprosthetic infection remains a challenge. Multiplex-PCR and biomarkers such as alpha-defensin are potentially useful and fast methods for detecting periprosthetic infection. This study compared these new methods with clinical assessment, conventional microbiological methods and histo-pathological examination. METHODS: Twenty-eight consecutive patients with 30 joints and a mean age of 67.7 years (range 39 to 88) with removal of total hip arthroplasty (THA) or total knee replacement (TKR) were included in this study...

PURPOSE: Loss of a fourth digit below the level of the proximal phalanx results in a weakened grip, loss of skilled movements, and the amputation stump is repeatedly traumatized. Transposition of an adjacent fifth digital ray can improve hand function and cosmetic appearance by closing the gap created by the missing digit. Digital ray amputation is not a commonly performed procedure. However, when performed correctly it can dramatically improve hand function and cosmesis. The aim of this study was to evaluate the functional and aesthetic results of the fifth ray radial translation and intercarpal arthrodesis in mutilating ring finger injuries...

PURPOSE: Subchondral screw abutment in osteosynthesis of joint fractures is an effective method to achieve sufficient screw grip. In this study we investigated if subchondral screw placement is possible without harming the overlying subchondral plate and joint cartilage iatrogenic. MATERIALS AND METHODS: A 3.5-mm conventional steel screw was placed in the tibia of ten sheep in distances between 1 and 7 mm beneath the joint cartilage. After a follow up of two and four months, evaluation of the subchondral bone and joint cartilage was performed by means of a histological osteoarthritis score, HRpQCT imaging and determination of the glycosaminoglycan content in the cartilage...

PURPOSE: Rotation of the lower limb in weight bearing long leg radiographs has a great impact on measured component and lower limb alignment parameters. We asked which rotational errors of long leg radiographs are present in a high volume centre and which radiological and clinical consequences arise regarding measured coronal component and lower limb alignment after total knee arthroplasty. METHODS: In 100 long leg radiographs coronal femoral and tibial component alignment and hip knee ankle angle (HKA) were measured...

PURPOSE: Because of the improvement of medical therapy and the corresponding increase in life expectancy, orthopaedic surgeons are obliged to perform more wide resections rather than intramedullary stabilization nailing for patients affected by tumours of the hip compared to the past. Wide resection often causes joint instability, so prosthetic reconstruction presents a higher risk of dislocation than in primary osteoarthritis cases. The aim of the present paper is to classify the indications for the dual mobility cup (DMC) hip prosthesis based on the anatomic structures involved in the disease and to analyse the rationale to reduce the risk of dislocation...
