A New Surgery Platform for Calcaneal Surgery: a Clinical Research

Study Overview
=================
Brief Summary
-----------------
Purpose: Study on the method of lateral nursing and surgical operating tables optimization in the calcaneal surgery. Method:Design combined surgical operating tables grouped according to the time of clinical application.58 patients with lateral calcaneus surgeries are divided into the control group of 29 patients and the experimental group with 29 patients. The traditional lateral method and calcaneus lateral surgery platforms are separately applied to compare the sliding of the affected limb during a surgery, the stability of the position, the difference of the surgical instruments fall and the satisfaction of the medical staff.Moreover,30 healthy volunteers are selected to experience the comfort level of the two placement methods.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: New surgery platform for calcaneal surgery<br>The lateral position surgical platform for calcaneus surgery is designed with a bottom board, mats in front and at back of calf and thigh, and two sizes of cover plates, using tunnel principle according to physiological curve of lower limbs. | Procedure: different types of surgery platforms<br>* 58 patients with lateral calcaneus surgeries are divided into the control group of 29 patients and the experimental group with 29 patients. The traditional lateral method and calcaneus lateral surgery platforms are separately applied in the groups.<br>|
| Experimental: Traditional lateral platform<br>The traditional lateral position makes the surgery platform bread-shaped arch surface by using medical mats and putting lower limbs superimpose on each other | Procedure: different types of surgery platforms<br>* 58 patients with lateral calcaneus surgeries are divided into the control group of 29 patients and the experimental group with 29 patients. The traditional lateral method and calcaneus lateral surgery platforms are separately applied in the groups.<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| The sliding frequency of the affected limb during a surgery with two methods | More or fewer times | Intraoperative | 
| The time patients'surgical position can last for in a surgery. | Necessary position stability is significant.For intraoperative fluoroscopy,surgeons need to keep the injured feet a fixing steady position with the help of different platforms.So,time the steady position can last for is recorded by the investigator separately. | Intraoperative | 
| The frequency of the surgical instruments fall with different methods | More or fewer times | Intraoperative | 
| The whole satisfaction level of the patients and medical staffs | Patients and medical staffs are asked for feelings about the utilization of the new surgical platform.Mark 0 is extreme poor.Mark 10 is very perfect,and the numbers between them are comments of varying degrees. | From the beginning of operation till 1 days postoperative | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Extra possible adverse effects due to the new surgical platform | Check adverse effects on the basis of influences on respiratory or circulatory systems and damages on patients' nerves or skin. | From the beginning of operation till 24 hours postoperative |
