PURPOSE: Management of proximal humeral tumours remains a surgical challenge. No study to date has assessed the quality of life scores following the composite reverse shoulder arthroplasty for this indication. We, therefore, evaluated function and quality of life following reconstruction with allograft for malignant tumour of the humerus. METHODS: A series of six cases of humeral tumour treated by a single surgeon in a single centre was reviewed after a mean follow-up of 5...

BACKGROUND: Earlier results with porous tantalum acetabular cups in revision THA generally have been favorable. Recently there has been some evidence presented that porous tantalum cups might decrease the risk of rerevision in the setting of revision hip surgery performed owing to prosthetic joint infection (PJI). As the data supporting this assertion come from a study with a limited study population, examining this issue with a large registry approach may be enlightening. QUESTIONS/PURPOSES: By combining results from two large, national registries, we asked: (1) Do porous tantalum cups show improved survival after revision THA compared with other cementless designs? (2) Does the use of porous tantalum cups influence survivorship when rerevision for PJI is the endpoint? METHODS: A total of 2442 first-time THA revisions with porous tantalum cups and 4401 first-time revisions with other uncemented cups were included in this collaborative study between the Australian and Swedish national joint registries...

Acetabular fractures potentially account for up to half of all pelvic fractures, while pelvic fractures potentially account for over one-tenth of all human bone fractures. This is the first biomechanical study to assess acetabular fracture fixation using plates versus cables in the presence of a total hip arthroplasty, as done for the elderly. In Phase 1, finite element (FE) models compared a standard plate method versus 3 cable methods for repairing an acetabular fracture (type: anterior column plus posterior hemi-transverse) subjected to a physiological-type compressive load of 2207N representing 3 x body weight for a 75kg person during walking...

BACKGROUND: Although standard instrumentation is the procedure most frequently used to implant a total knee arthroplasty (TKA), high rates of malalignment of tibial component are reported using this technique. Anatomical landmarks for sagittal alignment have been little investigated and the best reference axis which parallels the mechanical axis is yet to be established. HYPOTHESIS: Mapping the anterior tibial profile (ATP) may allow the identification of segmental zones of the ATP parallel to the mechanical axis which can be use to align the extramedullary rod...

Pilon fractures are notoriously difficult injuries to treat. The current published data on salvage procedures after failed pilon fractures includes both total ankle arthroplasty (TAA) and tibiotalar fusion, each with its own specific indications. However, no acceptable treatment algorithm addressing the complications of these limb salvage procedures is available. We present the case of a 23-year-old patient, who sustained a complex pilon fracture after a motor vehicle accident. The patient was referred to our institution after an initial fixation attempt, followed by subsequent failed TAA, which was complicated by an infected fusion attempt...

Total ankle replacement continues to become a more common treatment of end-stage ankle arthritis. A lateral approach total ankle implant system is an innovative approach for this treatment. We performed a retrospective review of 16 patients treated with lateral approach total ankle replacement. The implant was successful and retained in all cases during a follow-up period of 769 ± 221.3 days (25.3 ± 7.3 months). Initial satisfactory alignment was achieved in all cases. For patients in whom a frontal plane incongruent deformity was present preoperatively, a statistically significant correction was obtained (p = ...

BACKGROUND: Wrist hemiarthroplasty has emerged as a motion-sparing option for severe wrist arthritis. It is technically easy with advantages of limited bone resection and no risk of nonunion. Given the relative infancy of the procedure in clinical practice, there are limited data on patient outcomes. METHODS: Eleven patients were treated with wrist reconstructive hemiarthroplasty. Indications included 1 patient with scaphoid nonunion advanced collapse, 9 patients with scapholunate advanced collapse, and 1 patient with capitolunate arthritis...

Total knee arthroplasty (TKA) is effective in managing end-stage degenerative joint disease. Achieving favorable clinical outcomes is predicated on proper implant alignment, sizing, and rotation as well as adequate soft-tissue balancing. Modern TKA implants are designed to address the fundamental needs of attaining stability in both flexion and extension and of optimizing patellar tracking. Measured resection and gap balancing are the two different techniques used to implant the TKA components used today. Both techniques have been validated as durable and successful, and each has unique advantages and disadvantages...

Blood management strategies are integral to successful outcomes in many types of orthopaedic surgery. These strategies minimize blood loss and transfusion requirements, ultimately decreasing complications, improving outcomes, and potentially eliminating risks associated with allogeneic transfusion. Practices to achieve these goals include preoperative evaluation and optimization of hemoglobin, the use of pharmacologic agents or anesthetic methods, intraoperative techniques to improve hemostasis and cell salvage, and the use of predonated autologous blood...

Medicare currently requires a 3-night hospitalization for a patient to be considered for skilled nursing facility (SNF) placement. The purpose of this study was to analyze the relationship between length of stay and (a) insurance status and (b) readmission rates in Medicare-age patients undergoing primary total shoulder arthroplasty. A retrospective review of 251 primary consecutive total shoulder arthroplasty cases was performed. In patients discharged to SNF, Medicare insurance was associated with a significantly longer hospital stay (p < ...

Complex proximal humerus fractures in elderly patients represent a difficult problem for orthopaedic surgeons. Classically, treatment methods have included nonoperative management, open reduction and internal fixation, and hemiarthroplasty. Outcomes of nonoperative management for these complex fractures have been poor, and results of traditional operative techniques are variable at best. Over the past several years, reverse total shoulder arthroplasty (RTSA) has been increasingly employed in these injuries with encouraging results...

The treatment of superficial wound infections with local antibiotics is considered to be problematic as it is accompanied by an increased risk of resistance development and ineffectiveness in deeper regions. On the contrary, the local application of antibiotics is useful in arthroplasty and necessary if implants are utilized. The reason for this is the prevention of a rapid biofilm formation on foreign implants and a resulting infection may remain undiscovered until it becomes chronic. Apart from exogenous material, necrotic tissue (e...

BACKGROUND: Elective THA is associated with a high risk of thromboembolic events. Although these events may be less common now than they were in the past, they can be serious, and most patients undergoing the procedure therefore still receive thromboprophylaxis. However, controversy remains regarding whether to begin thromboprophylaxis before THA or after to best balance the risks of clotting and bleeding. QUESTIONS/PURPOSES: We asked the following questions: (1) Is there a difference in bleeding events with pre- versus postoperative thromboprophylaxis? (2) Is there a difference in thromboembolic episodes after THA between the two regimens? (3) How do the two approaches of thromboprophylaxis influence mortality, readmissions, and other complications? METHODS: We used a population-based followup design with predefined data based on international health codification to assess clinical effects of LMWH prophylaxis initiated before or after THA...
