Optimization of preoperative planning and intraoperative navigation at the shoulder replacement

There were 105 patients with shoulder replacement under our supervision (terms of supervision were up to 10 years). There were 43 men and 62 women. Age of patients was from 29 to 80 years. Two ways of optimization of shoulder replacement are offered: "Method of preoperative determination of the sizes of a head of shoulder joint endoprosthesis" (Patent of the Russian Federation N 2469670 d.d. 12.20.2012) and "Method for intraoperative navigation of a shoulder stem of joint" (Patent of the Russian Federation N 2467725 d.d. 11.27.2012). We reached the improvement of quality of the operation due to the fact of an installation of the implants which are as much as possible close to the anatomy of a normal shoulder joint by size and position

SHORT- AND MIDDLE-TERM RESULTS OF KNEE JOINT REPLACEMENT WITH ZIMMER NexGen CR AND LPS IMPLANTS

The article presents the experience gained by orthopedic unit of Saratov Regional Clinical Hospital at knee joint replacement with modern implants. We analyzed use of Zimmer NexGen CR and LPC implants for initial total knee joint replacement in 285 patients. The monitoring continued for 5 years. Good and excellent results were observed in 92% of cases. Pyogenic complications were observed in 2.3% of cases. The article describes the methods of surgical intervention and post-surgical rehabilitation. We consider our experience with Zimmer NexGen LPS and CR knee-joint implants as positive and prospective for further use

Primary endo-prothesis of shoulder joint at heavy traumatic damages of proximal segment of a shoulder bone and their consequences

Under our supervision there were 123 patients with terms of supervision till 7 years, with fractures,fracture-dislocations of an area of a shoulder joint and chronic damages of this area. There were 57 men and 66 women. All the patients were from 38 to 83 years old, the average age was 55,8 years. 44 patients had various kinds of an osteosynthesis and 79 - endoprosthesis of a shoulder joint. It was proved, that in patients of the senior age group, the expressed bony rarefication, a heavy accompanying pathology of a shoulderjoint (arthrosis of 2-3 grades, defeat of a joint at a number system diseases, etc.) and also at the treatment of consequences of traumas are unconditional, the preference should be given to endoprosthesis of a humeral joint, as to more effective method of treatment

Endoprosthesis replacement at the treatment of elbow joint defects

Results of 25 total endoprosthesis operations in patients with defects of the elbow joint of various ethiology are analysed. The endoprostheses produced by Endoservis (Russia] and Coоnrad/Mоrrey Zimmer (USA] were used. The technique of operation and postoperative rehabilitation is described in the article. The estimation of results of treatment was performed by «the Estimation of surgery of an elbow» (American Shoulder and Elbow Surgeons (ASES] Assessments; Richards R.R. et al. 1994]. Radiographically the results of treatment were estimated by the method of X-ray stability of the implants by O.A. Kudinov, V.l. Nujdin. The majority of patients undergoing arthroplasty of the elbow joint for its defects were of young age (40-45 years], and that has left its mark on the technology of operation and maintenance of the patients in different periods after surgery. The analysis of results of treatmentfor 1 year until 1-15 years after the operation was carried out. Good and excellent results, were received in 68 %, satisfactory - in 30 %. The unsatisfactory result of endoprosthesis surgery took place in 8 % of operated (2 patients]. It has been established that the endoprosthesis replacement for elbow joint defects in high-tech surgery is definitely an alternative to traditional methods of treatment, and in most cases should be seen as a method of choice for treatment of this disease

MEDIUM-TERM RESULTS OF PRIMARY HIP JOINT REPLACEMENT WITH ZIMMER IMPLANTS, PROVIDING CEMENT-RETAINED RESTORATION AND CEMENT-FREE RESTORATION

We observed 503 patients with various pathologies of hip joint. 555 interventions with total hip joint replacement were conducted. 52 patients were operated on both sides. Total number of male patients was 219; the number of female patients was 284. Age of patients varied from 18 to 82. 24 patients were under 25 y.o.; 117 patients were 26–40 y.o.; 232 patients were 41-60 y.o.; 130 patients were older than 60. Cement-free restoration of implants took place in 196 cases. Trilogy + VerSys ET combination was used in 156 cases; Trilogy + Alloclassic combination was applied in 40 cases. Hybrid restoration (ZCA + VerSys ET) was used on 297 patients; completely cement restoration (ZCA + CPT) was applied in 62 cases
