OBJECTIVE: There is limited research on the effectiveness of orthopedic robot-assisted treatment for sarcopenia combined with femoral neck fractures (FNF) in clinical settings. This study aimed to compare the clinical outcomes of orthopedic robot-assisted screw placement with traditional manual screw placement for treating sarcopenia combined with FNF.
METHODS: The retrospective study included patients with FNF under the age of 65 who were admitted to the Department of Orthopedics at XX Hospital Affiliated to XX University between January 2019 and March 2022 and underwent internal fixation with cannulated screws. Grip strength of the dominant hand was measured, and the skeletal muscle index (SMI) was calculated based on the muscle tissue area at the level of the 12th thoracic vertebrae on chest CT divided by height squared. Sarcopenia was diagnosed when SMI was below 42.6 cm2/m2 for men or 30.6 cm2/m2 for women. Patients were then grouped based on whether they underwent orthopedic robot-assisted surgery, as the robot-assisted (RA) group or the freehand (FH) group. Follow-up evaluations over 24-36 months included various parameters such as operation time, blood loss, X-ray shots, number of needle drilling, cannulated nail parallelism, C-reactive protein (CRP) levels, time to weight-bearing, perioperative infection, VAS (visual analogue scale) scores at 1 and 6 months post-surgery, Harris hip score at 6 months post-surgery, and incidence of nonunions and femoral head necrosis within 24 months post-surgery.
RESULTS: A total of 127 participants were enrolled in this study, with 46 individuals in the RG group and 81 in the FG group. Across both groups, factors such as gender, age, SMI, injury sides, Garden classifications, intraoperative blood loss, preoperative CRP, and VAS scores at 6 months post-surgery did not show statistically significant differences (p > 0.05). The RA group exhibited shorter operation time, fewer intraoperative X-ray shots, less needle drilling, and lower postoperative CRP levels compared to the FH group. The VAS score of the RA group was lower one month after surgery, whereas the Harris score was higher six months post-surgery (p < 0.05). The parallel angle of the hollow screws in the RA group was superior to that in the FH screw placement group, with an earlier time to bear weight on the ground post-surgery (p < 0.05). There were no statistically significant differences in incision infection, femoral neck nonunion (within 9 months after surgery), and patient satisfaction between the two groups (p > 0.05). Furthermore, the rate of femoral head necrosis after fracture within 2 years in the RA group was lower compared to the FH screw placement group, with statistically significant differences (p < 0.05).

UNASSIGNED: To compare the therapeutic efficacy of robot-assisted and manual screw placement techniques for the treatment of pelvic fractures.
UNASSIGNED: This study included patients with pelvic fractures admitted to our orthopedic department between January 2020 and January 2022. They were randomly assigned to either the robot-assisted group or the control group. Various parameters, including surgical duration, intraoperative bleeding, fluoroscopy frequency, postoperative pain, length of hospitalization, postoperative hematological indices, postoperative functional scores, and postoperative complications, were compared between the two groups.
UNASSIGNED: There were no significant differences in age, sex, body mass index, and preoperative hematological parameters between the two groups. The robot-assisted group exhibited significantly shorter surgical duration, lower fluoroscopy frequencies, lower postoperative pain scores, and shorter length of hospitalization compared to the control group. At 3 and 6 months postoperatively, patients in the robot-assisted group demonstrated significantly higher Majeed functional scores in comparison to the control group. However, there were no significant differences in Majeed scores at 12 months postoperatively. Moreover, there were no significant differences in postoperative complications between the two groups.
UNASSIGNED: Robot-assisted minimally invasive treatment of pelvic fractures using hollow screws effectively reduced surgical duration, mitigated intraoperative bleeding and postoperative pain, shortened hospital stays, and promoted faster functional recovery.

BACKGROUND: This reported procedure combines the orthopedic surgical robot with the unilateral biportal endoscopy-lumbar interbody fusion (UBE-LIF), utilizing the UBE\'s wide viewing field and operating space to perform minimally invasive decompressive fusion of the lesioned segment, and the orthopedic surgical robot\'s intelligence and precision to perform percutaneous pedicle screw placement. The advancement of this procedure lies in the superposition of advantages and offsetting disadvantages of the two new technologies, and the maximum effect of treatment is achieved with maximum minimization of invasiveness and precision under the monitoring of imaging instruments to maximize the benefit of patients, and this review reports a case of multiple-segment lumbar decompression and fusion surgery for lumbar disc herniation via robot-assisted UBE for reference.
METHODS: A 44-year-old patient presented to our hospital. Combining various clinical data, we diagnosed the patient with lumbar disc herniation with radiculopathy, lumbar spondylolisthesis, and lumbar spinal stenosis. We developed a surgical plan of \"UBE decompression + UBE-LIF + orthopedic surgery robot-assisted percutaneous pedicle screw implantation for internal fixation\". The results were satisfactory.
CONCLUSIONS: We present an extremely rare case of multiple-segment lumbar decompression and fusion surgery for lumbar disc herniation via robot-assisted UBE and achieved good results. Therefore, the technique is worthy of clinical promotion.

OBJECTIVE: To investigate the clinical effect of orthopedic robot combined with Starr pelvic reduction frame in the treatment of Tile type C pelvic ring fracture.
METHODS: From October 2019 to May 2021, 14 patients with type C pelvic ring fracture were treated with robotic combined with Starr pelvic reduction frame, including 9 males and 5 females. The age ranged from 33 to 69 years. All the 14 patients had fresh closed fractures without femur, tibia and fibula fracture. Surgery was completed from 4 to 7 d after hospital admission. During the operation, the X-ray carbon bed was used, the pelvic ring was reduced by Starr pelvis reduction frame, and pelvic ring fracture was treated by orthopedic robot. Operation time, bleeding volume, fluoroscopy times of single screw placement, fracture reduction quality, affected limb function and complications were observed. Radiological reduction was evaluated using Matta scoring standard, and clinical efficacy was evaluated by Majeed pelvic function scoring system at the final follow-up.
RESULTS: All of 14 patients successfully completed the operation, the operation time was 84 to 141 min, the bleeding volume was 20 to 50 ml, and the fluoroscopy times of single screw insertion was 4 to 9 times. All of 14 patients were followed up for 12 to 24 months. The healing time was 3 to 7 months. No complications such as fracture of internal fixation, screw loosening, infection and nerve injury were found. According to the evaluation criteria of Matta imaging reduction, 9 cases were excellent, 4 cases were good, and 1 case was fair. At the final follow-up, Majeed pelvic function scoring system was used:10 cases were excellent, 4 cases were good.
CONCLUSIONS: The treatment of type C pelvic ring fracture with robotic combined Starr pelvis reduction frame is simple, time-saving, less trauma, less complications and effective.

BACKGROUND: Robots are being used in a wide range of surgical procedures. However, in clinical practice, the efficacy of orthopedic robotic-assisted treatment of femoral neck fractures is still poorly reported, particularly in terms of screw placement accuracy, femoral neck fracture healing rates and postoperative functional recovery. Moreover, there is a lack of comparative analysis between robot-assisted surgery and traditional surgical approaches.
OBJECTIVE: The purpose of this study was to compare the clinical outcomes of patients with femoral neck fractures treated with TiRobot-assisted hollow screw fixation with those of patients with femoral neck fractures treated with traditional surgical approaches.
METHODS: This study included 112 patients with femoral neck fracture who were treated from March 2017 to October 2021 with percutaneous hollow screw internal fixation. These included 56 cases in the TiRobot-assisted surgery group and 56 cases in the standard surgery group. After at least 1 year of follow-up, the treatment outcomes of the two groups were compared, including the amount of intraoperative bleeding, the duration of intraoperative fluoroscopy, the number of guide pin positioning adjustments, the length of hospital stay, the accuracy rate of screw placement, the final Harris Hip Score, the fracture healing rate, and the rate of femoral head necrosis. Statistical analysis software was used to process and analyze the result.
RESULTS: The TiRobot-assisted group had a statistically significant improvement over the control group in terms of intraoperative bleeding, the duration of intraoperative fluoroscopy, the number of guide pin positioning adjustments, length of hospital stay, accuracy of screw placement and incidence of femoral head necrosis (P < 0.05). There was no statistically significant difference in time to surgery, final Harris hip score and fracture healing rate (P > 0.05).
CONCLUSIONS: This study shows that TiRobot-assisted surgery has the advantages of short hospital stay, high safety, minimally invasive, high success rate of nail placement, and can reduce the amount of intraoperative radiation and the incidence of femoral head necrosis, thus achieving satisfactory clinical outcomes, and is worthy of clinical promotion.

BACKGROUND: There are conflicting results for robot-assisted (RA) pedicle screw fixation compared with freehand (FH) pedicle screw fixation.
OBJECTIVE: This study was designed to retrospectively compare the accuracy and efficacy of RA percutaneous pedicle screw fixation and traditional freehand FH pedicle screw fixation in the treatment of thoracolumbar fractures.
METHODS: A total of 26 cases were assigned to the RA group, and 24 cases were assigned to the FH group. The operation time, bleeding volume, and visual analog scale (VAS) score 1 day after the operation, and the anterior/posterior (A/P) vertebral height ratio of the injured vertebrae at 3 days and at internal fixation removal 1 year after the operation were compared between the two groups. Pedicle screw position accuracy was assessed according to Gertzbein criteria.
RESULTS: The operation times of the RA group and FH group were 138.69 ± 32.67 minutes and 103.67 ± 14.53 minutes, respectively, and the difference was statistically significant. The intraoperative blood loss was 49.23 ± 22.56 ml in the RA group and 78.33 ± 23.90 ml in the FH group, and the difference was statistically significant. There was a significant difference in the A/P vertebral height ratio of the injured vertebrae 3 days after the operation compared with before the operation in both groups (P < 0.05). There was a significant difference in the A/P vertebral height ratio of the injured vertebrae 3 days after the operation compared with that at fixation removal in both groups (P < 0.05).
CONCLUSIONS: The application of RA orthopedic treatment for thoracolumbar fractures can achieve good fracture reduction.

OBJECTIVE: To investigate the clinical efficacy and advantages of Tianji orthopedic robot assisted cannulated screw internal fixation for femoral neck fracture.
METHODS: The clinical data of 41 patients with femoral neck fracture who underwent internal fixation with cannulated screws from January 2019 to January 2022 were retrospectively analyzed. According to different surgical methods, they were divided into Tianji robot group and traditional cannulated screw fixation group (traditional operation group). Among them, there were 18 patients in Tianji robot group including 8 males and 10 females with age of (56.00±4.22) years old, Garden typeⅠ (4 cases), type Ⅱ (11 cases), type Ⅲ (2 cases), and type Ⅳ (1 case). There were 23 patients in the traditional operation group, including 10 males and 13 females, aged (54.87±4.81) years old;there were 5 cases of Garden typeⅠ, 14 cases of type Ⅱ, 3 cases of type Ⅲ and 1 case of type Ⅳ. The operation time, intraoperative blood loss, fluoroscopy times, guide needle placement times, operation costs and other indicators were observed and compared between two groups. Harris score was used to evaluate hip joint function 12 months after operation.
RESULTS: The wounds of all patients healed in Grade A without complications. There were significant differences between two groups in terms of operation time, times of intraoperative fluoroscopy, times of guide needle placement, amount of intraoperative bleeding, and operation cost (P<0.05). All 41 patients were followed up for at least 12 months. The fractures of both groups were healed. There was no infection, screw loosening, fracture displacement and femoral head necrosis in Tianji robot group during follow-up;Screw loosening occurred in 2 patients in the traditional operation group during follow-up. At 12 months after operation, Harris hip joint function score of Tianji robot group was higher than that of traditional operation group in daily activity, lameness, joint activity score and total score (P<0.05).
CONCLUSIONS: Tianji robot assisted nail placement is a better method for the treatment of femoral neck fracture, which improves the surgical efficiency, is more accurate, has higher success rate of one-time nail placement, shorter operation time, less radiation, and has better hip joint function recovery after surgery.

UNASSIGNED: To investigate the short-term effectiveness and advantages of the orthopedic robot-assisted femoral neck system (FNS) fixation in the treatment of fresh femoral neck fractures compared with the traditional manual operation.
UNASSIGNED: A clinical data of 74 patients with fresh femoral neck fractures, who had undergone internal fixation with FNS between April 2020 and September 2021, was retrospectively analyzed. Among them, there were 31 cases of TiRobot-assisted operation (trial group) and 43 cases of traditional manual operation (control group). There was no significant difference between groups ( P>0.05) in terms of gender, age, cause of injury, time from injury to operation, fracture side and type. The fracture fixation time (intraoperative fracture reduction to the end of suture), invasive fixation time (incision of internal fixation to the end of suture), the number of placing key-guide needle, incision length, intraoperative blood loss, fracture healing, and Harris score of hip function were recorded and compared.
UNASSIGNED: All operations were performed with no neurovascular injury or incision complications. The invasive fixation time, intraoperative blood loss, the number of placing key-guide needle, and the incision length in the trial group were superior to the control group ( P<0.05), and there was no significant difference in fracture fixation time between groups ( P>0.05). All patients were followed up 4-16 months (mean, 7 months). The fracture did not heal in 1 patient of trial group, and the other fractures healed in 2 groups; the fracture healing time was (17.6±1.9) weeks in trial group and (18.2±1.9) weeks in control group, and there was no significant difference between groups ( t=0.957, P=0.345). At last follow-up, the Harris score of the trial group was 82.4±5.8, which was higher than that of the control group (79.0±7.7), but the difference was not significant ( t=-1.483, P=0.147).
UNASSIGNED: Orthopedic robot-assisted FNS fixation in the treatment of fresh femoral neck fractures has the similar short-term effectiveness as the traditional method, but the former has advantages in terms of operation time, intraoperative blood loss, and the number of placing key-guide needle, making the operation more minimally invasive and quicker, and more suitable for older patients.
