Ran Schwarzkopf, Erik Schnaser, Taiki Nozaki, Yasuhito Kaneko, Michael J Gillman
INTRODUCTION: Patient-specific implants and instruments (PSI) have been used in both knee and shoulder replacements due to the perceived benefits of improved surgical accuracy and efficiency. The proposed benefits of using a PSI in total hip arthroplasty (THA) are numerous and include reduction of operative time and improved mechanical and anatomical alignment leading to increased implant longevity, increased stability, and clinical outcomes. We describe a novel patient-specific instrumentation and a surgical method that may improve directed resection of acetabular bone and accurate cup placement during THA...

BACKGROUND: Compared with total shoulder arthroplasty (TSA), total shoulder surface replacement (TSSR) may offer the advantage of preservation of bone stock and shorter surgical time, possibly at the expense of glenoid component positioning and increasing lateral glenohumeral offset. We hypothesized that in patients treated for osteoarthritis with a sufficient rotator cuff, TSA and TSSR patients have comparable functional outcome, glenoid component version, and lateral glenohumeral offset...

OBJECTIVE: Multifocal osteonecrosis is rare. A zone of epiphyseal bone-marrow necrosis of three or more joints characterizes it. The most common risk factors are glucocorticoids intake and alcoholism. However, there is a series of other causes that could be incriminated in osteonecrosis, among which antiphospholipid syndrome. This case report, illustrates a primary antiphospholipid syndrome with only one clinical manifestation: multifocal osteonecrosis. OBSERVATIONS: A 30-year-old woman, with a medical history of left total hip replacement (THR), presents with severe right coxalgia and pain in both knees and shoulders...

Many patients prioritize the ability to return to sports following shoulder replacement surgeries, including total shoulder arthroplasty (TSA), reverse total shoulder arthroplasty (RTSA), and hemiarthroplasty (HA). While activity levels after hip and knee replacements have been well-established in the literature, studies on this topic in the field of shoulder arthroplasty are relatively limited. A review of the literature regarding athletic activity after shoulder arthroplasty was performed using the PubMed database...

INTRODUCTION: Total shoulder arthroplasty (TSA) has become a popular and successful surgery to treat advanced glenohumeral arthritis, rotator cuff arthropathy, and proximal humerus fractures. Historical data is available investigating the epidemiology of total shoulder arthroplasty with regard to patient characteristics, outcomes, and complications; however, there is a lack of studies investigating the most recent and up to date national trends related to shoulder replacement. The purpose of this study was to evaluate changes in the annual incidence, various demographics, and complications of TSA in America...

PURPOSE: To review the outcome of total elbow replacement (TER) in 21 patients after a mean of 64 months. METHODS: Records of 12 women and 9 men aged 32 to 78 (mean, 59.1) years who underwent 22 TERs for rheumatoid arthritis by a single surgeon were reviewed. Functional outcome was assessed using the disability of the arm, shoulder and hand (DASH) questionnaire. The range of movement and Kaplan- Meier survival curve was determined. Adequacy of cementation was assessed on immediate postoperative radiographs...

BACKGROUND: A porous tantalum glenoid component for total shoulder replacements was introduced in 2003 to promote biologic ingrowth. However, reports of component failure prompted design modifications. The purpose of this study is to present the largest series to date, of TSR with the second-generation Trabecular Metal™ glenoid component. METHOD: A radiologic and clinical evaluation of the second-generation TM glenoid was conducted in consecutive cases of 76 shoulders (66 patients) with a mean follow-up of 43...

OBJECTIVES: Chronic pain after total knee replacement (TKR) is not uncommon. Preoperative impaired conditioning pain modulation (CPM) has been used to predict chronic postoperative pain. Interestingly, exercises reduce pain sensitivity in patients with knee osteoarthritis. This pilot study investigated the association between exercise-induced hypoalgesia (EIH) and CPM on post-TKR pain relief. METHODS: Before and six months post-TKR, 14 patients with chronic knee osteoarthritis performed the cold pressor test on the non-affected leg and two exercise conditions (bicycling and isometric knee extension), randomized and counterbalanced...

BACKGROUND: Total shoulder arthroplasty for end-stage glenohumeral arthritis with severe glenoid bone loss poses a unique challenge for shoulder surgeons. Current surgical solutions are limited and associated with high complication rates. We hypothesized that a custom-made computer-aided design-computer-aided manufacturing (CAD-CAM) total shoulder replacement (TSR; Stanmore Implants Worldwide, Elstree, UK) resembling a total hip prosthesis could offer a reliable alternative for this challenging subset of patients...

BACKGROUND: Associations between socioeconomic position (SEP) and the uptake of primary total shoulder arthroplasty (TSA) is not well understood in the Australian population, thus potentially limiting equitable allocation of healthcare resources. We used the Australian Orthopaedic Association National Joint Replacement Registry (AOA NJRR) to examine whether geographic or socioeconomic variations exist in TSA performed for a diagnosis of osteoarthritis 2007-11 for all Australians aged ≥40 years...

Secure subscapularis repair is an essential element of total shoulder arthroplasty. Some surgeons prefer subscapularis peel because of ease of use, but some evidence suggests that lesser tuberosity osteotomy provides better fixation. The authors developed a novel, through-implant repair technique and performed a biomechanical study of its strength with cadaveric specimens. The authors obtained 20 matched pairs of cadaveric shoulders and inserted an uncemented short-stemmed humeral prosthesis that facilitates through-implant repair in all specimens...

BACKGROUND: Loosening of the glenoid component continues to be the main cause of medium and long-term failure of shoulder replacements. The purpose of this study was to evaluate the early clinical and radiographic results following use of an all-polyethylene pegged glenoid component designed for hybrid (biological and cement) fixation. METHODS: Eighty-three shoulders in 77 patients (mean age, 68.6 years) underwent total shoulder arthroplasty with a pegged hybrid-fixation component (bone-ingrowth glenoid and cemented peg)...

Background The elbow joint is a complex compound articulation, with a linking role within the upper limb kinematics. Its hinge function allows for proper placement of our working instrument (the hand) in the space surrounding us, directed by the shoulder joint. Both reliable mobility and stability are essential elements to allow for consistent bridging of the distance we aim to achieve in common daily activities. Sufficient flexion and extension are required to ensure both the patients' independence and the dignity...

Trabecular metal anchored glenoids (TMAGs) were developed to counter the pervasive problem of component loosening at the bone-cement interface in total shoulder arthroplasty. Increased failure rates associated with the glenoid component have been previously reported due to increased rates of glenoid failures. Our hypothesis was that in our patients, the failure rate of TMAG implants is similar to or less than reported failure rates of traditional all polyethylene glenoid components. A medical chart review of 66 consecutive patients treated with a TMAG total shoulder replacement was conducted including clinical and radiographic follow-up...

The number of cases with rheumatoid arthritis who requires arthroscopic synovectomy is declining, but it is still a useful procedure in combination with effective pharmacologic disease control. For the destruction of glenohumeral joint, total shoulder arthroplasty is effective for pain relief and functional outcome for patients without rotator cuff impairment. The reverse shoulder arthroplasty has been shown favorable short-term results, but need a careful indication for rheumatoid shoulder with poor bone stock and bone quality...
