In this paper we introduce Shape Memory Alloy (SMA) for designing the tibial part of Total Knee Arthroplasty (TKA) by exploiting the shape-memory and pseudo-elasticity property of the SMA (e.g. NiTi). This would eliminate the drawbacks of the state-of-the art PMMA based knee-spacer including fracture, sustainability, dislocation, tilting, translation and subluxation for tackling the Osteoarthritis especially for the aged people of 45-plus or the athletes. In this paper a Computer Aided Design (CAD) model using SolidWorks for the knee-spacer is presented based on the proposed SMA adopting the state-of-the art industry-standard geometry that is used in the PMMA based spacer design...

BACKGROUND: Open fractures of tibia have posed great difficulty in managing both the soft tissue and the skeletal components of the injured limb. Gustilo Anderson III B open tibial fractures are more difficult to manage than I, II, and III A fractures. Stable skeletal fixation with immediate soft tissue cover has been the key to the successful outcome in treating open tibial fractures, in particular, Gustilo Anderson III B types. If the length of the open wound is larger and if the exposed surface of tibial fracture and tibial shaft is greater, then the management becomes still more difficult...

BACKGROUND: Open tibial shaft fractures require emergent care. Treatment with intravenous antibiotics and fracture débridement within 6 to 24 hours is recommended. Few studies have examined outcomes when surgical treatment is performed >24 hours after occurrence of the fracture. METHODS: This retrospective study included 227 patients aged ≥18 years with isolated open tibial shaft fractures in whom the time to initial débridement was >24 hours. The statistical analysis was based on time from injury to surgical débridement, Gustilo-Anderson classification, method of fixation, union status, and infection status...

BACKGROUND: Mobile-bearing total ankle replacement (TAR) enables motion at the tibial implant-polyethylene insert interface. This motion could lead to coronal translation of the talus relative to the tibia and may affect radiographic outcome. We aimed to assess the translation of the talus before and after mobile-bearing TAR to determine whether translation of the talus after TAR is associated with coronal plane alignment of the lower limb and hindfoot as well as to investigate the complications associated with talar translation...

BACKGROUND: Amputation has been the standard surgical treatment for distal tibia osteosarcoma owing to its unique anatomic features. Preliminary research suggested that microwave-induced hyperthermia may have a role in treating osteosarcoma in some locations of the body (such as the pelvis), but to our knowledge, no comparative study has evaluated its efficacy in a difficult-to-treat location like the distal tibia. QUESTIONS: Does microwave-induced hyperthermia result in (1) improved survival, (2) decreased local recurrence, (3) improved Musculoskeletal Tumor Society (MSTS) scores, or (4) fewer complications than amputation in patients with a distal tibial osteosarcoma? METHODS: Between 2000 and 2015, we treated 79 patients for a distal tibia osteosarcoma without metastases...

This article reports the use of elastic suture as an adjuvant in surgical wound closure caused by decompressive fasciotomy after compartment syndrome associated with a compound fracture of the tibia. Widely used in other medico-surgical specialties, this technique is unusual in orthopedics surgery, but the simplicity of the procedure and the successful outcome observed in this case allows for its consideration as indicated for situations similar to that presented in this study.

OBJECTIVE: This study aimed to evaluate the inter- and intra observer reproducibility of the radiographic score of consolidation of the tibia shaft fractures. METHODS: Fifty-one sets of radiographs in anteroposterior (AP) and profile (P) of the tibial shaft treated with intramedullary nail were obtained. The analysis of X-rays was performed in two stages, with a 21-day interval between assessments by a group of nine evaluators. To evaluate the reproducibility of RUST score between the evaluators, the intra-class correlation coefficient (ICC) with a 95% confidence interval was used...

OBJECTIVE: To investigate the effects of intramedullary nail removal after tibial fracture repair. METHODS: Sixty patients at our hospital were enrolled in a prospective study and divided into moderate/severe knee pain (visual analog scale (VAS) ≥ 4) and mild/no knee pain (VAS < 4) groups after interlocking intramedullary nailing. Variables studied included the distance from the tip of the nail to the tibial plateau and the front of the tibia on a normalized lateral X-ray, the VAS score of knee and ankle pain, the range of motion of the knee and ankle, and Johner-Wruhs criteria before, 6 weeks after operation, and at the last follow-up...

A 9-month-old filly donkey was referred for a comminuted diaphyseal fracture of the right tibia. Surgical osteosynthesis, with multiple lag screws and a neutralization plate, was performed for anatomical reconstruction. Despite a good gait condition, delayed bone consolidation and a bone gap were evident on follow up radiographic evaluations. Due to delayed healing, autologous platelet-rich plasma (PRP) was injected on the surface of the tibia. Increased bone consolidation was evident on radiographs one month after the PRP injection...

INTRODUCTION: Tibial plateau fractures often occur in conjunction with soft-tissue injuries of knees. The hypothesis of this study is that parameters of CT imaging can predict intra-articular soft-tissue injuries. PATIENTS AND METHODS: Patients who underwent arthroscopically assisted reduction and internal fixation (ARIF) for acute tibial plateau fractures performed by a single orthopedic surgeon between 2005 and 2015 were included in this retrospective study. Patients with concomitant ipsilateral femoral fractures, who had received revision surgery or who had undergone index surgery more than 30days from the event were excluded...

The objective of this prospective study was to evaluate the patient-reported outcomes for patients with complex tibial fractures treated with a ring fixator. The secondary aim was to analyse the variables affecting patient-reported outcomes and time to union. Fifty-six patients participated in the study. The mean age at the time of fracture was 56.5 years (range 30-86). All fractures united during the study period. The ring fixator was removed at an average of 25.3 weeks (range 9-53). During treatment, the function and QOL increased with time...

INTRODUCTION: Tibial intramedullary nailing remains a common tibial fracture fixation method. Tibial nailing indications continue to expand. Neurovascular complications from tibial nailing have been described; however, the proximity of distal tibial locking bolts to the anterior tibial artery (ATA) variants has not. MATERIALS AND METHODS: 52 cadaveric legs were dissected identifying three common ATA variants. Each ATA variant received an intraluminal wire to facilitate fluoroscopic identification...

Fracture treatment is an old endeavour intended to promote bone healing and to also enable early loading and regain of function in the injured limb. However, in today's clinical routine the healing potential of the initial fracture haematoma is still not fully recognized. The Arbeitsgemeinschaft für Osteosynthesefragen (AO) formed in Switzerland in 1956 formulated four AO principles of fracture treatment which are still valid today. Fracture treatment strategies have continued to evolve further, as for example the relatively new concept of minimally invasive plate osteosynthesis (MIPO)...

Several plate systems for high tibial osteotomy (HTO) have been developed to stabilize the opening wedge of an osteotomized tibia. Among them, the TomoFix system, having a quasi-straight and T-shaped design, has been widely adopted in the literature. However, this system is implemented by inserting a lag (i.e., cortical) screw through the proximal combi-hole, to deform the plate and pull the distal tibia toward the plate. This process potentially induces plate springback and creates an elastic preload on the osteotomized tibia, especially at the lateral hinge of the distracted wedge...

BACKGROUND: Although relatively rare, non-unions and mal-unions of tibial plateau fractures present significant challenges for the orthopedic surgeon. With careful pre-operative planning, tibial plateau mal-union or non-union revision surgery with intra-articular and varus opening osteotomies can provides good functional results when performed early (within 1 year) after primary surgical procedure. QUESTIONS/PURPOSES: We present our treatment algorithm for approaching and treating non-union or mal-union of tibial plateau fractures...
