1 Effect of Tendon Release and Delayed Repair on the Structure of the Muscles of the Rotator Cuff: An Experimental Study in Sheep by C. Gerber, D.C. Meyer, A.G. Schneeberger, H. Hoppeler, and B. von Rechenberg J Bone Joint Surg Am Volume 86(9):1973-1982 September 1, 2004 ©2004 by The Journal of Bone and Joint Surgery, Inc.

2 Drawing of the right shoulder in a sheep with the sensor in situ. C. Gerber et al. J Bone Joint Surg Am 2004;86:1973-1982 ©2004 by The Journal of Bone and Joint Surgery, Inc.

3 The sequence of the experimental steps and the respective studies. C. Gerber et al. J Bone Joint Surg Am 2004;86:1973-1982 ©2004 by The Journal of Bone and Joint Surgery, Inc.

4 The mean retraction (and standard deviation) of the tendon end measured on computed tomographic scans. C. Gerber et al. J Bone Joint Surg Am 2004;86:1973-1982 ©2004 by The Journal of Bone and Joint Surgery, Inc.

5 The atrophy of the involved infraspinatus muscle was measured as the square area of the infraspinatus on longitudinal computed tomography sections and was indicated as a mean percentage (and standard deviation) of that of the control side.

6 Fatty infiltration of the infraspinatus muscle on the involved side and the contralateral, uninvolved control side of the six sheep. C. Gerber et al. J Bone Joint Surg Am 2004;86:1973-1982 ©2004 by The Journal of Bone and Joint Surgery, Inc.

7 Typical light microscopic appearance of the toluidine blue-stained muscle at the time-points represented by 0 to 5. C. Gerber et al. J Bone Joint Surg Am 2004;86:1973-1982 ©2004 by The Journal of Bone and Joint Surgery, Inc.

8 Electron microscopic changes in the fibrillar volume per fiber, fiber volume per muscle volume, interstitial fat, and other interstitial cell volume. C. Gerber et al. J Bone Joint Surg Am 2004;86:1973-1982 ©2004 by The Journal of Bone and Joint Surgery, Inc.

9 Electron microscopic changes in the mitochondrial volume per fiber and in the capillary volume of the whole muscle. C. Gerber et al. J Bone Joint Surg Am 2004;86:1973-1982 ©2004 by The Journal of Bone and Joint Surgery, Inc.

10 Transverse computed tomography scan showing a section of a sheep at forty weeks after the tendon release. C. Gerber et al. J Bone Joint Surg Am 2004;86:1973-1982 ©2004 by The Journal of Bone and Joint Surgery, Inc.
