Objective: To investigate the clinical and radiographic results of total shoulder arthroplasty (TSA) for damaged shoulder joints with osteoarthritis (OA) and rheumatoid arthritis (RA).Patients and Methods: From 1999 to 2012 inclusive, we performed 19 total shoulder arthroplasties in 17 patients. A total of sixteen shoulders, five with OA and 11 with RA, from 15 patients were followed up for more than six months. All patients were female, with an average age of 71 years, and an average follow-up period of three years. Preoperative magnetic resonance imaging showed that the supraspinatus tendon was intact in five shoulders (intact group), and torn or thin in 11 shoulders (damaged group), respectively. Clinical outcomes were assessed using the Japanese Orthopedic Association (JOA) score, Disabilities of the Arm, Shoulder and Hand (DASH) score and range of motion (ROM). Radiographic loosening of the humeral stem and glenoid component was evaluated according to the criteria described by Stewart.Results: The average JOA score improved from 39.9 points preoperatively to 80.3 points at the final follow-up. The average DASH score improved from 70.1 points to 56.0 points. The range of active flexion, abduction and external rotation significantly improved postoperatively. Radiolucent line evaluation around the glenoid component was observed in two shoulders. There was no significant difference in the improvement of the JOA score between the intact group and the damaged group. In both groups, pain relief was experienced postoperatively, but the improvement in ROM consisting of flexion, abduction and external rotation, was significantly greater in the intact group than in the damaged group. The postoperative JOA score showed a strong inverse correlation with the preoperative DASH score.Conclusion: The results of the current study showed satisfactory clinical outcomes of TSA for OA and RA, particularly with the treatment effect of good postoperative pain relief. Clinical outcome may depend on the preoperative status of the rotator cuff and the function of the upper extremity.

Jehovah's Witnesses refuse blood transfusions on the basis of their religious belief. We report our experience with total hip arthroplasty without blood transfusion in a Jehovah's Witness.<br>The patient was a 70-year-old woman who had been receiving treatment for rheumatoid arthritis for 34 year and had been taking anti-platelet agents for atrial fibrillation and hypertension. Plain radiographs revealed severe erosions (Larsen Grade 4) in the right hip. We used a cemented femoral component and reamed the acetabulum gently to minimize any bleeding, while performing intraoperative blood-salvaging autotransfusion.<br>We carried out hybrid total hip arthroplasty with a cementless acetabular component and a cemented femoral component. The operation time was 62 minutes, intraoperative blood loss was 50ml, and postoperative blood loss was 90ml. The preoperative hemoglobin level was 9.9g/dl, and the lowest hemoglobin level was 6.8g/dl after surgery. At the final follow-up, the patient was able to walk with a T-shaped walking stick, and her Japanese Orthopaedics Association score (right/left) was 80 points/81 points on.<br>We considered that the use of a cemented femoral component and gentle reaming of the acetabulum were factors that reduced bleeding during total hip arthroplasty.

OBJECTIVE: To assess the reliability and sensitivity of a novel scoring method to evaluate the radiographic appearance of and longitudinal changes including joint remodeling in large joints with early and established rheumatoid arthritis (RA). METHODS: The ARASHI study group devised new radiographic scoring systems (Status score; range 0-16 points, and Change score; range -11 to 12 points) for evaluation of large joints with RA. Radiographs showing anterior/posterior views of large joints (shoulder, elbow, hip, knee, and ankle joints) taken at two time points (mean interval 2.3 years) were collected from 25 patients with established RA (5 patients for each of the 5 joints, 50 films in total), and an additional 5 films of each joint with severe joint destruction were collected from 5 different sets of RA patients. After consensus on the definition of each component and reader training, images were evaluated using the Larsen's grading system and the ARASHI Status and Change score by 9 independent senior orthopedic surgeons. The reliability was estimated by intra-class correlation coefficients (ICCs) and measurement error by 95% confidence intervals of minimum detectable change (MDC95). RESULTS: ARASHI Status score and Change score significantly correlated with Larsen's grade (r = 0.89, P < 0.0001) and follow-up-baseline differences in Larsen's grade (r = 0.83, P < 0.0001), respectively. Inter-reader ICCs were very high for both Status score (0.88, 95% confidence interval [CI], 0.83-0.92, P < 0.001) and Change score (0.92, 95% CI, 0.87-0.96, P < 0.001). Intra-reader ICCs were also very high for both Status score (0.92, 95% CI, 0.71-0.98, P < 0.001) and Change score (0.97, 95% CI, 0.91-0.99, P < 0.001). The MDC95 for inter-reader agreement were 4.18 (25% of maximum obtainable score, MOS) and 4.99 (21% of MOS) for Status score and Change score, respectively. The MDC95 for intra-reader agreement was acceptable with 2.82 (17% of MOS) and 3.02 (13% of MOS) for Status score and Change score, respectively. CONCLUSION: The ARASHI scoring method showed good inter-/intra-reader reliability with high ICCs and acceptable MDC95 with respect to each large joint and the components of both Status and Change scores. The results suggest that the ARASHI scoring method might be useful for the assessment of status, as well as longitudinal monitoring of destruction and remodeling of large joints with RA.

We report a case of 4th metacarpal head collapse of a 19-year-old healthy man. MRI revealed T1 low and T2 high regions in the collapsed 4th metacarpal head, as well as in the right 3rd and left 4th metacarpal head. Our initial diagnosis was occult compression fracture due to avascular necrosis, known as Dieterich's disease. However, pathological findings of surgically resected right 4th metacarpal head were compatible with transient osteoporosis and metacarpal head fracture followed by active tissue repair. The autologous osteochondral transplants from costchondral junction survived and maintained their size and shape even at 10-year follow-up.

関節リウマチ(RA)の診断治療において、単純X線による関節病変の評価はその所見に特徴的なものが多く、また病態を反映していることなどもあり有用なツールとして広く使用されている。しかし、生物学的製剤の導入を契機に早期診断また治療効果、寛解評価のための鋭敏な検査が必須となり、単純X線のlimitationのためMRIや超音波検査など他のmodalityとの併用が提唱されている。早期診断には不向きであるが、網羅的評価に長けること、reproducibleであるなど利点も多いため単純X線の見方や評価法について熟慮しておく必要がある。多種の評価法が報告されており、どの評価法を用いるかについては各検査法の長所短所を考慮し、目的に応じた評価法の選択を検討する必要がある。(著者抄録)
