The paper presents a descriptive kinematic radiographic study of changes in a shape, orientation and function of the lumbar spine in the sagittal plane due to various surgical interventions for lumbar degenerative disease. Literature analysis evidences for only few studies of spine shape and static interrelations in a spinal motion segment after surgical treatment. Any complex assessments of changes in a spine shape in the sagittal plane, its spatial orientation and function after surgical intervention has not been performed. The study includes a comparative kinematic computer analysis of pre- and postoperative radiographs of the lumber spine of 157 patients, including 62 patients after decompression, 50 after posterior interbody fusion, and 45 after dynamic transpedicular fixation. It was found that the overall range of motion has reduced during three years after any kind of surgical intervention; that surgery at the L5–S1 level takes the most significant biomechanical effect; and that decompressing and stabilizing procedures at the L5–S1 level facilitate a lumbar lordosis restoration. The L5–S1 interbody fusion results in interbody space increase and segmental angle decrease at the surgery level. The L4–L5 interbody fusion increases the range of motion in a subjacent motion segment; dynamic transpedicular fixation takes a minimal effect on a lumbar spine shape and vertebral interrelations and allows preserving the physiological mobility of all motion segments.

Reverse Total Shoulder

Reverse total shoulder arthroplasty (rTSA) is used to improve pain and function in arthritic, rotator cuff deficient shoulders. Surgical intervention is considered successful if range of motion and stability of the joint is maximized and force to abduct the arm is minimized. Implant hardware positioning may affect these outcome measures.

Results of comparative study of posterior interbody fusion (PLIF) and transforaminal interbody fusion (TLIF) in degenerative lumbar spine pathology are presented. Total number of patients was 101. In 47 patients (1st group) transpedicular fixation, decompression and interbody fusion with one cage (TLIF) was performed. In 54 patients (2nd group) transpedicular fixation via posteromedial approach, decompression of intracanal neurovascular structures and interbody fusion with two interbody implants (PLIF) was applied. Complex evaluation of surgical treatment results was performed in 52 patients in 6-12 months after surgery. It was shown that application of either of the techniques resulted in 95-98% cases of interbody block formation. Differential approach to application of those interbody fusion techniques and the advantages of TLIF over PLIF, i.e. simplicity and higher safety of performance, lower intraoperative blood loss and duration of surgical intervention, were presented.

Number Of Patients

In recent years, there has been an unprecedented increase in the number of patients undergoing treatment with interbody fusion devices for degenerative disease of the lumbar spine. These devices can be placed either anteriorly or posteriorly. With the advent of minimally invasive surgery and the increasing ability of general surgeons to perform transperitoneal procedures laparoscopically, a new laparoscopic technique has been developed for placing lumbar interbody fusion devices. Although this procedure has some advantages over posterior lumbar interbody fusion, it is not without significant risk, and the learning curve is steep. The authors review a series of 32 consecutive patients who underwent single-level laparoscopic anterior lumbar interbody fusion at L4–5 or L5–S1 over a 2-year period for the treatment of single-level lumbar degenerative disease. In this report they review the technical aspects of the procedure and the important lessons they have learned through their early experience with this technique.
