ABSTRACT
Objective:To observe the effect of early weight-bearing on the appropriate population with intertrochanteric fracture after surgery. Methods:From April, 2017 to December, 2018, a total of 45 patients with Evans-Jensen type II intertrochanteric fracture and fracture reduction as positive medial cortex support (PMCS) after proximal femoral nail anti-rotation (PFNA) fixation were randomly divided into control group (n = 22) and experimental group (n = 23). Weight-bearing as tolerated (WBAT) was initiated from six weeks after surgery in the control group, and within 48 h after surgery in the experimental group. The frequency of WBAT in two groups increased gradually from three times a day for ten minutes a time to five times a day for 20 minutes a time until clinical healing of fracture. The length of stay, hospital cost, the fracture healing time and the complication incidence were compared between two groups, as well as the scores of Visual Analogue Scale (VAS) and Harris Hip Score at six weeks, three months and six months after surgery. Results:Compared with the control group, the length of stay was shorter (t = 3.716, P < 0.01), the hospital cost was lower, but no significant difference was found (t = 1.540, P > 0.05), and the fracture healing time was shorter (t = 6.248, P < 0.001) in the experimental group. The complication incidence was lower in the experimental group, but there was no significant difference (χ2= 2.198, P > 0.05). Six weeks, three months and six months after surgery, there was no significant difference in the score of VAS between two groups (t < 1.330, P > 0.05). The score of Harris Hip Score was significantly higher in the experimental group than in the control group six weeks after surgery (t = -5.115, P < 0.001), however, no significant difference was found in other time points (|t| < 1.799, P > 0.05). Conclusion:Early weight-bearing within 48 h after PFNA fixation for Evans-Jensen type II intertrochanteric fractures and reduction with PMCS could shorten the length of stay, shorten the bony healing time and promote early recovery of hip function.
ABSTRACT
OBJECTIVE@#To study and analyze the clinical effect of the self-developed new adjustable weight-bearing rehabilitation brace in the rehabilitation of the femoral intertrochanteric fracture after the operation of PFNA.@*METHODS@#From July 2015 to June 2017, 62 patients with typeⅡ (Evans-Jensen classification) intertrochanteric fracture of femur were treated with PFNA internal fixation. There were 11 males and 19 females in the routine rehabilitation group, with an average age of (70.73± 6.09) years;17 males and 15 females in the brace rehabilitation group, with an average age of (71.25±6.60) years. Among them, the patients in the routine rehabilitation group recovered according to the routine method, and the patients in the support rehabilitation group used the self-developed new adjustable weight-bearing rehabilitation support of lower limbs to assist the early rehabilitation. The pain intensity(VAS score), weight-bearing of affected limb, clinical healing time of fracture, Harris score and complications were recorded and analyzed.@*RESULTS@#Nine patients lost their visit half a year later, the other 53 patients were followed up for 9 to 18 months. The VAS score at 1, 3, 6 months after operation of brace rehabilitation group was lower than that of routine rehabilitation group(<0.05). The weight bearing of the limbs in the rehabilitation group was significantly higher than that in the conventional rehabilitation group(<0.05), but the clinical healing time of fracture in the brace rehabilitation group was shorter than that in the routine rehabilitation group(<0.05). In addition, the Harris score of the postoperativebrace rehabilitation group was better than that of the conventional rehabilitation group(<0.05). The incidence of complications was lower than that of the conventional rehabilitation group(=0.048).@*CONCLUSION@#In the rehabilitation of Evans Jensen typeⅡintertrochanteric fracture after PFNA internal fixation, the new self-developed adjustable weight-bearing rehabilitation brace can significantly relieve postoperative pain, regulate and moderately increase the stress stimulation at the fracture end, so as to promote fracture healing, accelerate the recovery of hip joint function, reduce the incidence of complications, and its clinical effect is safe and reliable.

<p><b>OBJECTIVE</b>To observe the short-term clinical results of the adjacent segment degeneration after the implantation of Coflex system at the interspinous space of adjacent segment to lumbar fusion.</p><p><b>METHODS</b>Fifty patients with grade III disc (Thompson MRI classification) of adjacent segment to lumbar fusion were included and divided alternately into two groups according to the order of hospitalization from January to November 2009. Coflex system was implanted at the interspinous space of adjacent segment to lumbar fusion in 25 patients as Coflex group, the other 25 patients did not have any surgical treatment were as control group. The followed up time was 2 years. Visual analogue scale (VAS) score of low back pain, changes of disc height and motion range of adjacent segment to lumbar fusion on X-ray imaging were evaluated by independent sample t-test or paired samples t-test.</p><p><b>RESULTS</b>There were 22 patients in Coflex group and 21 patients in control group were followed up 2 years post-operation. The difference of VAS score between two groups was no significance (P > 0.05). In Coflex group, the change of postoperative disc height was no significance (P > 0.05), but the motion range was significantly reduced to 47% of the preoperative value (t = 7.99, P < 0.05). In control group, the postoperative disc height decreased slightly, without significant difference to the preoperative value (P > 0.05). Between the two groups, no differences of the disc height and motion range were found before operation, but the differences of the disc height changes (t = 6.7, P < 0.05) and motion rang (t = -14.5, P < 0.05) were significant in 2 years post-operation. No complications such as Coflex system loosen, immigration and spinal process fracture were occurred.</p><p><b>CONCLUSIONS</b>Coflex system can obviously limit the motion range and maintain the disc space height of adjacent segment to lumbar fusion, and prevent its degeneration in some degree.</p>
