BACKGROUND: A patient with arthritis usually experiences the progression of symptoms over time. At some stage, the patient may decide that the symptoms have reached a level of severity that leads him or her to elect to proceed with joint replacement; we refer to this degree of symptom severity as the "tipping point." Our goal was to study the factors that influenced the tipping point for patients undergoing elective shoulder arthroplasty. METHODS: We analyzed the characteristics of 931 patients undergoing shoulder arthroplasty to determine the factors affecting the tipping point as characterized by the patients' comfort and function at the time they determined their symptoms had progressed to the point when this elective surgery was merited...

We previously reported the results at an average of 4.5 years after treatment of 176 patients with the ream-and-run arthroplasty. In the present study, we present the patient self-reported functional outcomes and clinical implant survival of the original cohort at a mean of 10 years (range, 5 to 16 years). Twenty-eight (16%) of the 176 patients had a subsequent procedure, 11 (6%) died, and 30 (17%) had <5 years of follow-up. The Simple Shoulder Test (SST) score at the time of the latest follow-up was a median of 11 points (interquartile range, 9 to 12 points) and a mean (and standard deviation) of 10 ± 2...

INTRODUCTION: Hemiarthroplasty with concentric glenoid reaming (known as "ream and run") may be an option for treating glenohumeral arthritis in younger patients with a biconcave glenoid. The goal of this study was to evaluate early results of this technique. METHODS: Two senior, fellowship-trained shoulder surgeons (G.R.W. and M.D.L.) performed a retrospective review of 23 patients (24 shoulders) with a biconcave glenoid and end-stage degenerative glenohumeral arthritis treated with hemiarthroplasty with concentric glenoid reaming...

BACKGROUND: The ream-and-run procedure can provide improvement in shoulder function and comfort for selected patients with primary glenohumeral arthritis who wish to avoid a prosthetic glenoid component. The purpose of this study was to evaluate factors associated with medialization of the humeral head after this procedure as well as the relationship of medialization to the clinical outcome. METHODS: We collected patient, shoulder, and procedure characteristics along with Simple Shoulder Test (SST) scores before surgery and at the time of follow-up...

H Zwipp
About 90 % of all cases of painful posttraumatic ankle arthritis can be very successfully treated with a minor invasive ankle arthrodesis technique by using a small anterior approach and a fixation with four 6. 5 mm screws of which the posteromedial and transfibular one are inserted percutaneously. The results with this standardized procedure have been reported previously as excellent and good in a mid-term run of 6 years (34). This technique leads to a high union rate of 99% (92 of 93) with rapid bone healing within 8 ± 2 weeks, it causes a low minor complication rate of 8 % and enables a significant increase of the AOFAS ankle/hindfoot score (17) from 36 preoperatively to 85 postoperatively as well as a midtarsal movement of 24° ± 16°...

Interactions between proteins and nucleic acids are frequently analyzed using electrophoretic mobility shift assays (EMSAs). This technique separates bound protein:nucleic acid complexes from free nucleic acids by electrophoresis, most commonly using polyacrylamide gels. The current study utilizes recent advances in agarose gel electrophoresis technology to develop a new EMSA protocol that is simpler and faster than traditional polyacrylamide methods. Agarose gels are normally run at low voltages (∼10 V/cm) to minimize heating and gel artifacts...

BACKGROUND: Although shoulder arthroplasties generally are effective in improving patients' comfort and function, the results are variable for reasons that are not well understood. QUESTIONS/PURPOSES: We posed two questions: (1) What factors are associated with better 2-year outcomes after shoulder arthroplasty? (2) What are the sensitivities, specificities, and positive and negative predictive values of a multivariate predictive model for better outcome? METHODS: Three hundred thirty-nine patients having a shoulder arthroplasty (hemiarthroplasty, arthroplasty for cuff tear arthropathy, ream and run arthroplasty, total shoulder or reverse total shoulder arthroplasty) between August 24, 2010 and December 31, 2012 consented to participate in this prospective study...

PURPOSE: The purpose of this paper is to provide some essential and basic information concerning the ream and run technique for shoulder arthroplasty. METHODS: In a total shoulder arthroplasty, the humeral head prosthesis articulates with a polyethylene glenoid surface placed on the bone of the glenoid. Failure of the glenoid component is recognised as the principal cause of failure of total shoulder arthroplasty. By contrast, in the ream and run procedure, the humeral head prosthesis articulates directly with the glenoid, which has been conservatively reamed to provide a stabilising concavity and maximal glenohumeral contact area for load transfer...

BACKGROUND: Active and young patients who place frequent demands on their shoulder present a treatment dilemma when glenohumeral arthritis progresses to a point at which surgical intervention is considered. Humeral head replacement with nonprosthetic glenoid arthroplasty ("ream-and-run") has been proposed to address the limitations of total shoulder arthroplasty and hemiarthroplasty in this population. Several reports from a single institution have shown substantial improvement in self-assessed comfort and function after this procedure...

BACKGROUND: The arthritic triad of glenoid biconcavity, glenoid retroversion, and posterior displacement of the humeral head on the glenoid is associated with an increased risk of failure of total shoulder joint replacement. Although a number of glenohumeral arthroplasty techniques are being used to manage this complex pathology, problems with glenoid component failure remain. In that the ream and run procedure manages arthritic pathoanatomy without a glenoid component, we sought evidence that this procedure can be effective in improving the centering of the humeral head contact on the glenoid and in improving the comfort and function of shoulders with the arthritic triad without the risk of glenoid component failure...

BACKGROUND: One of the main goals in total hip replacement is to preserve the integrity of the hip kinematics, by well positioning the cup and to make sure its initial stability is congruent and attained. Achieving the latter is not trivial. METHODS: A finite element model of the cup-bone interface simulating a realistic insertion and analysis of different scenarios of cup penetration, insertion, under-reaming and loading is investigated to determine certain measurable factors sensitivity to stress-strain outcome...

REVIEW

Loosening of the glenoid component is a frequent cause of failure of total shoulder arthroplasty (TSA). The etiology of glenoid component loosening is multifactorial and includes aseptic osteolysis, rotator cuff insufficiency, soft tissue instability, and infection. A loose glenoid component is frequently associated with a substantial loss of glenoid bone, which necessitates additional procedures to implant a new component. Several studies have shown that patients with a new glenoid component have better clinical outcomes, which makes successful glenoid reimplantation a priority...

Nineteen cases were studied retrospectively between 1982 and 1993. All had been stabilised immediately by external fixators. Free or pedicle flap and early bone graft was carried out as required.Bone stability was obtained by Hoffmann or Orthofix fixators which allowed later manoeuvres for skin covers. The stabilisation by the fibula was attempted by intertibio-fibula grafting (ITF). Skin cover was obtained in 13 cases by pedicle flaps, in 4 by a free flap and 2 cases healed by secondary intention. The local flaps were 5 medial gastrocnemius or soleus flaps, 4 fasciocutaneous flaps, 3 medial gastrocnemius muscular cutaneous flaps and one cross-leg flap...

COMPARATIVE STUDY
Frederick A Matsen, Akash Gupta
BACKGROUND: The technique and results of shoulder arthroplasty are influenced by glenohumeral pathoanatomy. Although some authors advocate a routine preoperative CT scan to define this anatomy, ordering a CT scan substantially increases the cost and the radiation exposure for the patient. QUESTIONS/PURPOSES: We asked whether measurements of arthritic shoulders on a standardized axillary view are reliable; if postoperative radiographs can reliably show the changes in glenoid anatomy and glenohumeral relationships after shoulder arthroplasty, and if the axillary view can show differences in glenohumeral pathoanatomy in the different sexes and disease types...

Following a post-traumatic incident, orthopaedic surgeons often struggle to look for an abundant source of alternative bone graft because the bone defect is too big or when nonunion is refractory to treatment. We present two cases where the patients' bone grafts were harvested from the healthy femur. This process involved the use of a new intramedullary reamer, which allowed the bone graft to be harvested simultaneously during the reaming process.

BACKGROUND: Knowledge of the factors affecting the prognosis for improvement in function and comfort with time after shoulder arthroplasty is important to clinical decision-making. This study sought to identify some of these factors in 176 consecutive patients undergoing the ream-and-run procedure. METHODS: The time course for improvement in patient function and comfort was determined for the entire group as well as for subsets by sex, age, diagnosis, preoperative function, and surgery date...

Evaluation of paper brightness in multipage documents is a practice of forensic document examiners when there is a question of a page insertion or substitution. This article demonstrates that occasional errors occur in the manufacturing process that affects the consistency of paper brightness. The inconsistency of paper brightness may therefore influence conclusions reached in authenticating documents. Reams of multipurpose paper, from 21 manufacturers, were examined. When assessing the individual pages of each package with an ultraviolet light, approximately 30% of the reams revealed differences in paper brightness...

RANDOMIZED CONTROLLED TRIAL

It is generally accepted that in tibial fractures the results of reamed intramedullary nailing are better than those of unreamed. However, it is not known whether the clinical effects of reaming are cumulative or if minimal reaming would induce the same beneficial effects as more extensive reaming. This international multicentre study has investigated the effects of different degrees of reaming. 100 patients with closed diaphyseal tibial fractures were prospectively randomised in two centres. Method of treatment was reamed nailing up to 12 mm inserting an 11 mm tibial nail (n: 50), and minimally reamed nailing up to 10 mm inserting a 9 mm tibial nail (n: 50)...
