When modeling wave propagation in infinite space, it is necessary to have stable absorbing boundaries to effectively eliminate spurious reflections from the truncation boundaries. The SH wave equations for Perfectly Matched Layers （PML） are deduced and their Crank-Nicolson scheme are presented in this paper. We use the second-, sixth-, and tenth-order finite difference and pseudo-spectral algorithms to compute the spatial derivatives. Two numerical models, a homogeneous isotropic medium and a multi-layer model with a cave, are designed to investigate how the absorbing boundary width and the algorithms determine PML effects. Numerical results show that, for PML, the low-order finite difference algorithms have fairly good absorbing effects when the absorbing boundary is thin, whereas, high-order algorithms always have good absorption when the boundary is thick. Finally, we discuss the reflection coefficient and point out its shortcomings, which is why we use the SNR to quantitatively scale the PML effects,

The long head of the biceps tendon （LHBT） pathology has been implicated as a common source of shoulder pain. The patients may be more resistant to conservative treatment than those with isolated subacromial impingement. Even though, the surgical options of this disease remain controversial. It has been reported that tenotomy and tenodesis of the biceps tendon were usually utilized. However, persistent pain, deformity, and muscle cramping were frequently observed. Transfer of the LHBT to the conjoint tendon was originally described by Post and Benca in 1982.4 Verma et all has performed the transfer under arthroscopy since 2004. Eighty percent of their patients reported good results with a minimum 2 years of follow-up. However, there was a steep learning curve to become proficient in their technique. We devised a more convenient transfer compared with O＇Brien＇s technique. Six patients received our modified arthroscopic transfers from May 2006 to May 2007. All of them obtained good results.
