Massive rotator cuff tears defying primary repair have been treated with debridement, arthroscopic subacromial decompression, partial repair, muscle-tendon transfer, and joint prosthesis, among other techniques. However, the treatment results have not been satisfactory compared with those of small- to medium-sized rotator cuff tears; each procedure has its merits and demerits, and currently, there is no single established method.
For massive rotator cuff tears defying primary repair, the arthroscopic patch graft procedure has been reported as an effective surgical procedure, and this procedure is chosen as the first-line treatment in our department. In this procedure, suture anchors are generally used to fix the patch graft to the footprint on the side of the greater tuberosity. However, tendon-to-bone healing is frequently difficult to achieve, and bone-to-bone healing seems more advantageous for the repair of the rotator cuff attachment site.
To improve the results of treatment, a new patch graft procedure was developed, in which the iliotibial ligament with bone was collected at Gerdy's tubercle and the bone was anchored to the footprint on the side of the greater tuberosity. With this procedure, excellent results were obtained, although only short-term results are available at present. The technique and its results so far are reported.
BACKGROUND:The placement of the suture line for interatrial patches in complete and incomplete atrioventricular canal defect repairs varies from surgeon to surgeon despite established anatomic knowledge of the atrioventricular conduction system. This study describes our technique for it and reviews early and long-term outcomes. METHODS:Between 1980 and 1999, 64 infants and children underwent repair of either complete (n=39) or incomplete (n=25) atrioventricular canal defects. Thirty-four of the children (53.1%) had Down's syndrome. The suture line for the interatrial patch originated on either the artificial or native ventricular septal crest and continued leftward above the annulus of the left inferior leaflet of the atrioventricular valve at the posteroinferior corner. All stitches were placed in a horizontal mattress or U-shaped fashion. RESULTS:The operative survival rate was 94% (4 early deaths) and the overall survival rate was 85% (6 late deaths).
How To Do A Suture
Atrioventricular heart blocks occurred in none of the patients. Although left-sided atrioventricular function significantly improved with repair, two patients (3.1%) required reoperation for valve replacement because of residual or recurrent insufficiency. CONCLUSIONS:This suture technique for interatrial patches is straightforward and results in a low incidence of heart block and a low re-operation rate for left atrioventricular valve insufficiency.
