Proximal tibia fracture

Proximal tibia depression fracture often occur isolated or in conjunction with complex fracture presentations and elevation of such depression is required to retard arthritis in long term. Conventional open reduction by sub meniscal approach has many percutaneous alternatives from arthroscopy assisted reduction to balloon tibioplasty. Few authors even reported usage of PCL jig and percutaneous pins to elevate, while the primary author has previously described an instrument to elevate the depressed fragment percutaneously...

BACKGROUND: This work investigated the differences in the biomechanical properties of open reduction and internal fixation (ORIF) and percutaneous minimally invasive fixation (PMIF) for the fixation of calcaneal fractures (Sanders type II and III calcaneal fractures as examples) through finite element analysis. METHODS: Based on CT images of the human foot and ankle, according to the principle of three-point fixation, namely the sustentaculum tali, the anterior process and the calcaneal tuberosity were fixed...

Halicephalobus gingivalis is a free-living nematode that occasionally causes infections in horses. We report a rare case of limb fracture of horse caused by infection with H. gingivalis. An 8-year-old mare was referred to the Veterinary Hospital of the Federal University of Lavras with claudication grade 5 of the right hind limb, that had been started 3 months ago. The patient had aseptic arthritis in the tarsal joint and edema that extended to the quartile. The radiographic examination showed punctate osteolysis with exacerbation of bone trabeculation along the calcaneus, talus, proximal epiphysis of the third metatarsal and distal epiphysis of the tibia...

The combination of plate and intramedullary nailing has been established as the treatment of proximal tibial fractures. Nevertheless, at the distal end of the tibia, the application of the plate-assisted intramedullary nailing is rarely applied as a therapeutic technique. This technical note demonstrates the use of the reduction plating technique for nail insertion as the management of distal tibia fractures.

Bilateral defects around the knee joint following fracture of the proximal tibia (Schatzker type V & VI) are difficult to reconstruct because of the unavailability of local tissue. A bicondylar proximal tibial fracture requires a bilateral approach and dual plates for fracture fixation. Because of extensive dissection during plating and extended zone of trauma, the suture lines occasionally dehisce resulting in soft tissue defects on both sides of the proximal tibia. Because of its bilateral nature, the defect requires 2 flaps...

In this research, an experimental biomechanics construct was developed to reveal the mechanics of distal tibial fracture by submitting synthetic tibiae to cyclic loading, resulting in a combined stress state due to axial compression and bending loads. The synthetic tibia was fixed at the knee but allowed to rotate in the coronal and sagittal planes at the ankle. The first three loading regimes lasted for 4,000 cycles/each, and the final until ultimate failure. After 12k ± 80 cycles, the observed failure patterns closely resembled distal tibial fractures...

AIM: To facilitate the posterolateral approach to the posterior malleolus patients are often positioned prone initially, then turned supine to complete fixation at the medial malleolus. We sought to define observed differences in the radiographic appearance of implants relative to the joint line, in prone and supine positions. METHODS: A 3.5 mm tubular plate and a 3.5 mm posterior distal tibial periarticular plate were applied sequentially to 3 individual cadaveric legs, via a posterolateral approach...

Tibial plateau fractures (TPFs) are orthopedic challenges with multiple injury modalities and clinical presentations. TPFs are often classified using the Schatzker classification system, which can dictate management. In our case, a 37-year-old male presented at an orthopedic specialty hospital with right knee pain after a fall from a truck ramp. X-rays and CT imaging demonstrated a comminuted bicondylar TPF in the emergency room with metaphyseal dissociation. The patient was placed in a knee immobilizer, made non-weight bearing, and scheduled for outpatient follow-up with a local orthopedic surgeon...

OBJECTIVES: Stroke survivors frequently encounter physical complications. This study aimed to evaluate the impact of stroke on bone mineral density (BMD) and assess the risk of post-stroke osteoporosis or osteoporotic fractures. DESIGN: Systematic review and meta-analysis. SETTING AND PARTICIPANTS: We systematically searched Medline, Embase, and the Cochrane Database of Systematic Reviews to identify longitudinal studies reporting the influence of stroke on BMD, osteoporosis, and osteoporotic fractures...

PURPOSE: The topic of elective implant removal (IR) in healed fractures of the lower extremity remains controversial, particularly when unspecific symptoms of discomfort, which cannot be quantified, are the primary indication. This study aims to assess indications and outcomes of elective IR of the lower extremity, focusing on unspecific symptoms of discomfort and patient satisfaction postoperatively. MATERIALS AND METHODS: The retrospective cohort study was conducted at a single level I academic trauma center...

CASE: A 30-year-old male was admitted in our hospital having an open left distal femoral fracture with 9-cm segmental bone defect and a closed proximal left tibial fracture. He was treated successfully using a Hybrid (Titanium Cage and Bone Graft) Masquelet Induction Membrane Technique (MIMT). His femoral fracture united 3-months post - operatively. The left tibia was treated initially with two locking plates. Following infection, a 3-cm tibial bone gap was treated with external fixation and conventional MIMT...

RATIONALE: Extremity injuries resulting from motor vehicle collisions, especially those leading to bone-exposed wounds, present challenges for achieving effective wound coverage. Such injuries are susceptible to complications including infections, osteomyelitis, and unexpected amputations due to inadequate blood supply. Severe traumatic degloving injuries often entail damage to the surrounding blood vessels, making local or free flaps impractical choices in many cases. Consequently, treatment options may vary based on distinct clinical scenarios, with no standardized guidelines available...

INTRODUCTION: The aim is to report early clinical results of an experimental surgical procedure, injecting bone void filler, for patients with lower extremity rheumatoid arthritis (RA) insufficiency fractures. CASE REPORT: We used a cross-sectional design with retrospective follow-up. Patient-reported outcomes were reported by the body-region specific questionnaires, knee injury and osteoarthritis outcome score (KOOS), or foot and ankle outcome score (FOAS). The Eq5D-5L questionnaire reported overall health-related quality of life (QoL)...

An 11-year-old boy underwent a bone single-photon emission computed tomography/computed tomography (SPECT/CT) scan 3 months after fracturing his right tibia. The standardized uptake values (SUVs) of the growth plates in his right tibia were higher compared to those in the left tibia. One year later, the right leg was 10 mm longer than the left leg with higher SUVs in the right tibial growth plates. After performing epiphysiodesis at the right proximal tibia, the leg-length difference (LLD) decreased from 17 to 12 mm with the decrease of SUVs in the growth plates of the right tibia...

PURPOSE: The purpose of this study was to demonstrate the clinical utility of controlled posterior condylar milling (CPCM) in gap balancing while minimally resecting the tibia during fixed-bearing unicompartmental knee arthroplasty (UKA). METHODS: This study is a retrospective cohort study. Patients who underwent medial UKA for isolated medial compartment osteoarthritis with a minimum follow-up of 2 years were included. The patients were divided into two groups: the conventional group (n = 56) and the CPCM group (n = 66)...

This case study explains the complete care of a 45-year-old male patient who had a high-impact road injury that resulted in a displaced proximal tibial fracture. Substantial soft tissue damage was discovered during the initial assessment, requiring careful thought before undergoing surgery. A customized physiotherapy program was instituted after an incremental strategy involving open reduction and internal fixation. The patient made a satisfactory functional recovery, regaining nearly normal mobility and going back to daily activities within 12 weeks despite difficulties encountered during the rehabilitation phase, including temporary postoperative complications...

The management of chronic extensor mechanism injuries represents a significant challenge for orthopaedic surgeons, with numerous options for graft choice and fixation construct, but no clear consensus on which technique achieves optimal outcomes. Although there is little published data regarding outcomes of different fixation methods, small case series have demonstrated modest success using Achilles tendon bone block allografts and transverse patellar screw fixation. In this technical note, we describe a surgical technique for the treatment of a chronic inferior pole patella fracture, with extensor mechanism reconstruction using an Achilles tendon allograft with suture tape augmentation...

Coronal-plane intra-articular fractures of the femoral condyle (Hoffa fractures) are rare, and difficult to diagnose and treat. They mostly result as a consequence of high-energy trauma and are combined with concomitant fractures (patellar, tibia shaft) and/or soft-tissue damage. A plain X-ray can miss the diagnosis initially and therefore computerized tomography scan is recommended, which can also help in the preoperative planning. The vast majority of these fractures are unicondylar (mostly lateral condyle fractured)...

BACKGROUND: This study evaluated tibia's macroscopic structure, mechanical properties, and bone microarchitecture in rats with type 1 diabetes mellitus (T1DM). METHODS: Eighteen animals were divided into three groups (n=6): non-diabetic (ND), diabetic (D), and diabetic+insulin (DI). T1DM was induced by streptozotocin; insulin was administered daily (4IU). The animals were euthanized 35 days after induction. The tibiae were removed and analyzed using macroscopic, micro-computed tomography (micro-CT) and three-point bending...

Osteoporosis poses a major public health challenge, and it is characterized by low bone mass, deterioration of the microarchitecture of bone tissue, causing a consequent increase in bone fragility and susceptibility to fractures and complicating bone fixation, particularly screw implantation. In the present study, our aim was to improve implant stability in osteoporotic bone using a thermoresponsive hyaluronan hydrogel (HA-pNIPAM) to locally deliver the bisphosphonate zoledronic acid (ZOL) to prevent bone resorption and bone morphogenetic protein 2 (BMP2) to induce bone formation...
