Overall, two or more plates were shaped and implanted on the glenoid, spine, or the lateral and medial borders of the scapula according to the size and location of the allografts. CP-868596 manufacturer These plates were then used to fix the host scapula to the allografts with screws. The resected partial clavicle of one patient (treated with alcohol devitalization) was fixed with a plate to its original position while the distal clavicles of the remaining

six patients were bound with Dacron tape. After implanting the allografts, the abduction mechanism, including the deltoid and rotator cuffs, were reconstructed using the remaining muscles. Posteriorly, deltoid reconstruction was achieved in two patients by tenodesis to the trapezius and intraosseous

sutures. The uninvolved deltoid was reattached to its stumps on the allograft, the host acromion process, or the clavicle. The remaining muscles were either sutured to their corresponding stumps or were tenodesed to predrilled holes in the allografts. Rotator cuff reattachment was achieved in four patients. The articular capsule and deltoid were either well preserved and/or reconstructed in all seven patients. Two patients (#3 and 4) required local intraoperative radiotherapy NSC 683864 in vitro in the muscles surrounding the scapular allograft using I125. Postoperative rehabilitation programs The upper extremity was placed in an abduction brace at a functional position for four weeks postoperatively. Range of motion (ROM) and motor strengthening exercises for the hand and elbow were performed immediately postoperatively and shoulder isometric exercises were initiated within five days postoperatively. Later, isotonic and resistance muscle training were included in the patients’ rehabilitation programs after removal of the brace. Results The median follow-up period for the seven patients followed in this case series was 26 Fludarabine price months (range, 14–50 months). ISOLS-based BCKDHA functional scores ranged from 21 to 28 points (mean, 24) with a mean functional rating of 80% (range, 70–93%). As shown in Table 3, the range of

active shoulder abduction and forward flexion motion were 40°–110°and 30°–90°, respectively and all patients retained a high degree of hand and elbow function. Satisfactory shoulder contour was achieved in all patients (Figure 3, Figure 4, Figure 5). Three patients (#4, 6, and 7), whose rotator cuffs were resected, had lower total ISOLS scores (22, 21, and 23 points, respectively) than the other four patients and demonstrated a limited range of shoulder abduction and flexion. Figure 3 The postoperative plain radiograph shows the scapular allograft reconstruction. Figure 4 A 3-D computed tomography reconstruction taken 14 months after the procedure shows satisfactory healing at the host-graft junction together with slight bone resorption. Dislocation of the shoulder joint and local recurrence is not present. Figure 5 The shoulder abduction function and appearance 14 months postoperatively.
