A follow-up study was conducted to examine the postoperative clinical outcomes of modified Spizty's method (Spizty) and combination of Spizty and intertrochanteric osteotomy (combined operation) . Fifty-four patients (65 hip joints) aged from 17 to 52·years (average age 34.2 years) who underwent the operation at least five years prior were studied. Seventeen of 54 cases (19 joints) were classified as pre-stage osteoarthrosis of the hip; Spizty was performed on 12 joints and the combined operation on 7 joints. The remaining 37 cases (46 joints) were early stage osteoarthrosis; Spizty and the combined operation were performed on 23 joints each and some cases underwent additional muscle release. Clinical assessment according to the Japanese Orthopaedic Association score (JOA score) was performed. AHI, CE and Sharp's angle in reontgenogram were measured. Results before and after operation were compared. In the pre-stage cases, JOA score improved from 77.3 before operation to 93.2 points after operation; AHI increased from 60.7 to 96.3%; CE angle increased from 9.2° to 41.8°; and Sharp's angle decreased from 49.0° to 37.8°. In the early stage cases, JOA score improved from 66.3 before operation to 89.4 points after operation; AHI increased from 52.6 to 93.8%; CE angle increased from 2.4° to 37.00; and Sharp's angle decreased from 51.4°to 39.3°. No statistically significant differences in improvement were detected between the two stages or the two surgical methods. AHI, CE and Sharp's angles in the postoperative reontgenograms improved to within normal range in all cases. Sufficient covering of the acetabular shelf to the femoral head is speculated to account for the clinical improvement. These surgical methods are easy to perform and postoperative clinical outcomes are stable, and they are useful for treatment of pre-and early stage osteoarthrosis in young and middle-aged adults.

While some experts have been talking about the decline of local communities, at present there are many charitable local activities for someone, for communities, and for society. However, some of inhabitants mainly elderly people living alone and child-rearing mothers cannot obtain information on their living area because they have few opportunity to interact with the local residents. In order to reduce person who are isolated from local community due to the lack of information and realize the new kind of relationship suitable for the current social system, the local community needs a mechanism where both the isolated person and the person contributing to community can easily recognize each other's existence and connect them. Therefore, we develop a smartphone application named “Tamemap” aiming at a society where all local people are informally connecting in the region. Tamemap provides a function by which users living the region can transmit and catch small activities called micro events in their area. From the result of the real operation so far, Tamemap had been able to support users mainly people of child-rearing generation and seniors who need local information. Also, through the information sharing of micro events, Tamemap had been able to support the activities of users connecting two or more independent local communities.
