INTRODUCTION:
This study was conducted to evaluate the efficacy of postoperative computed tomography (CT) measurements of aortic lumen volumes in predicting aortic-related complications following acute type A aortic dissection (ATAAD) repair.
METHODS:
We conducted a single-institution retrospective aortic volumetric analysis of patients after ascending aorta replacement performed during 2001-2015. The volumetric measurements of total lumen (total-L), true lumen (TL), false lumen (FL), as well as the TL:FL ratio from the first and second postoperative computer angiograms were obtained. A generalised structural equation model was created to analyse the predictive utility of TL:FL ratio.
RESULTS:
One hundred and twenty-five patients underwent surgical intervention, of whom 97 patients were eventually discharged and analysed for postoperative complications. A total of 19 patients were included in the final analysis. Patients with late postoperative aortic complications had a significantly higher FL volume and total-L volume on the first (FL volume P = 0.041, total-L volume P = 0.05) and second (FL volume P = 0.01, total-L volume P = 0.007) postoperative scans. The odds of having aortic complications were raised by 1% with a 1 cm 3 increase in total-L volume and by 2% with a 1 cm 3 increase in FL volume. The TL:FL ratio was significantly lower in patients who developed complications.
CONCLUSION
Postoperative CT volumetric measurements in patients who developed complications are characterised by a significant increase in the FL volume and total-L volume from the first postoperative scans. Patients with disproportionately expanded FL presenting with TL:FL ratios less than 1 were associated with aortic complications. Hence, the TL:FL ratio may be a reliable and useful parameter to monitor postoperative disease progression and to evaluate the risk of late complications in ATAAD patients.

The paper reports acupuncture treatment for one case of oculomotor nerve palsy after cranial-orbital communicating tumor surgery. The acupoint prescription was composed of the local acupoints of the eyes (Yansanzhen, Tijian, Cuanzhu [BL2], Yuyao [EX-HN4] and Sizhukong [TE23]), the acupoints on the head, face and neck (Yangbai [GB14], Sibai [ST2] and Fengchi [GB20]), Guanyuan (CV4) on the abdomen, and those on the four limbs (Hegu [LI4], Zusanli [ST36], Shenmai [BL62] and Zhaohai [KI6]). The point-to-point needling technique with the eyelid lifted was operated at Tijian, Cuanzhu (BL2), Yuyao (EX-HN4), and Sizhukong (TE23). Warm needling with moxa cone placed on the needle handle was operated at Guanyuan (CV4) and Zusanli (ST36), and the usual needling technique was delivered at the rest acupoints. The treatment was given once daily, discontinued for 1 day after every 6 treatments. One course of treatment was composed of 7 days, and 6 courses were required. After treatment completion, the upper eyelids were basically symmetrical and the bilateral eye cracks were equal, the double vision appeared occasionally. No recurrence and no aggravation were reported in 1 month of follow up visit.

OBJECTIVE:
To investigate the effectiveness of 5G remote robotic surgery in the treatment of pelvic fractures.
METHODS:
A retrospective analysis was conducted on the clinical data of 160 patients with pelvic fractures admitted between July 2023 and June 2024 who met the selection criteria. Among these patients, 80 underwent internal fixation surgery with the assistance of 5G remote robotic surgery (5G group), while 80 received local robotic surgical assistance (control group). Baseline characteristics, including gender, age, body mass index, disease duration, cause of injury, and fracture classification, were compared between the two groups, and no significant difference was found ( P>0.05). The incision length, operation time, intraoperative blood loss, hospital stay, accuracy of screw placement, maximum residual displacement postoperatively, quality of fracture reduction, incidence of complications, Majeed pelvic function score and classification at last follow-up were recorded and compared between the two groups.
RESULTS:
In the 5G group, 180 screws were implanted during surgery, while 213 screws were implanted in the control group. The 5G group demonstrated significantly reduced intraoperative blood loss and shorter incision length compared to the control group ( P<0.05). No significant difference was observed between the two groups in terms of operation time or hospital stay ( P>0.05). Radiographic evaluation revealed excellent and good reduction rates of 98.8% (79/80) in the 5G group and 97.5% (78/80) in the control group, while excellent and good screw placement accuracy rates were 98.3% (177/180) in the 5G group and 95.8% (204/213) in the control group. No significant difference was found between the two groups in maximum residual displacement, reduction quality, or screw placement accuracy ( P>0.05). All patients were followed up 7-16 months (mean, 11.3 months), with no significant difference in follow-up duration between the groups ( P>0.05). No perioperative or follow-up complication, such as wound infection, iatrogenic fractures, iatrogenic neurovascular injury, screw loosening or breakage, or nonunion, were observed in either group. The control group exhibited a worse degree of gait alteration compared to the 5G group ( P<0.05), while no significant difference was found in incidences of squatting limitation or persistent pain ( P>0.05). At last follow-up, no significant difference was observed between the groups in Majeed pelvic function scores or grading ( P>0.05).
CONCLUSION
Compared with the local surgery group, 5G remote robotic surgery supported by remote expert technical guidance demonstrated smaller incision lengths, less intraoperative blood loss, and fewer postoperative complications, and was shown to be a precise, minimally invasive, safe, and reliable surgical method.

OBJECTIVE:
To compare the effectiveness and shoulder function of reverse total shoulder arthroplasty (RTSA) and open reduction and internal fixation (ORIF) in the treatment of Neer three/four-part proximal humeral fractures in the elderly.
METHODS:
Randomized controlled analysis was conducted on 68 patients over 70 years old with Neer three/four-part proximal humeral fractures treated with RTSA or ORIF between January 2020 and June 2022. The patients were randomly divided into RTSA group ( n=32) and ORIF group ( n=36). There was no significant difference ( P>0.05) in the baseline data such as age, gender, body mass index, injured side, Neer classification, and preoperative Charlson comorbidity index, visual analogue scale (VAS) score, Constant shoulder score, Oxford shoulder score (OSS), and hemoglobin (Hb). The operation time, intraoperative blood loss, reduction of Hb on the 3rd day after operation, hospital stay, total cost of hospitalization, complication incidence, range of motion of shoulder joint at 2 years after operation, VAS score before operation and at 5 days and 1 month after operation, Constant shoulder score and OSS score before operation and at 2 years after operation, and imaging results during follow-up were recorded and compared between the two groups.
RESULTS:
Compared with the ORIF group, the RTSA group had longer operation time, less intraoperative blood loss, and higher total cost of hospitalization ( P<0.05). There was no significant difference in Hb reduction on the 3rd day after operation between the two groups ( P>0.05). The VAS scores significantly improved in both groups at 5 days and 1 month after operation ( P<0.05), but there was no significant difference between the two groups ( P>0.05). All patients were followed up 26-35 months, with an average of 31.2 months. In the RTSA group, there were 2 cases of poor healing of superficial incision and 1 case of transient nerve injury. There was no complication such as bone resorption around the prosthesis, lucent band, prosthesis loosening, or periprosthetic fracture in all patients. In the ORIF group, there was 1 case of poor healing of superficial incision, 3 cases of nonunion of fracture, 1 case of arthritis secondary to humeral head necrosis, and 1 case of bone absorption of large tuberosity, and no displacement or fracture failure of internal fixation was found in all patients. There was no significant difference in the incidence of complications [9.4% (3/32) vs 16.7% (6/36)] between the two groups [ OR (95% CI): 0.828 (0.171, 4.014), P=0.814]. In the RTSA group, 28 cases were graded 0 and 4 cases were graded 1 at 2 years after operation. Constant and OSS scores of RTSA group were significantly better than those of ORIF group ( P<0.05). The Constant score was significantly better than ORIF group in activity and strength, range of motion, lifting, abduction, and external rotation ( P<0.05), and there was no significant difference in pain, daily function, and internal rotation between the two groups ( P>0.05). The RTSA group had a significantly greater range of motion in lifting, abduction, and external rotation than ORIF group ( P<0.05), but there was no significant difference in internal rotation between the two groups ( P>0.05).
CONCLUSION
Application of RTSA as the initial treatment of Neer three/four-part proximal humeral fractures in the elderly can achieve better rehabilitation of joint activity and lower risk of early reoperation, and improve the quality of life of elderly fracture patients. However, the difficulty of revision and the high cost of treatment require the surgeon to pay full attention and strictly grasp the indications.

Chinese Journal of Reparative and Reconstructive Surgery 2025;39(5):569-573
OBJECTIVE:
To compare the effectiveness of early versus delayed closed reduction and percutaneous Kirschner wire fixation in the treatment of pediatric supracondylar humerus fractures.
METHODS:
A retrospective analysis was conducted on 468 children with supracondylar humerus fractures, who were admitted between January 2020 and December 2023 and met the inclusion criteria. Among them, 187 children were treated during 12 hours after injury (early operation group) and 281 were treated after 12 hours (delayed operation group). There was no significant difference between the two groups ( P>0.05) in the gender, age, injury mechanism, fracture side and type, while there was significant difference in interval from injury to operation ( P<0.05). The operative outcomes, including the operation time, intraoperative blood loss, the length of hospital stay, fracture healing time, elbow function assessed by Flynn criteria at 3 months after operation, and complications, were compared.
RESULTS:
Compared to the delayed operation group, the early operation group demonstrated significantly shorter operation time and less intraoperative blood loss ( P<0.05). There was no significant difference in the length of hospital stay between the two groups ( P>0.05). All children were followed up 3-12 months. The follow-up time was (6.7±2.9) months in the early operation group and (6.9±2.8) months in the delayed operation group, showing no significant difference between the two groups ( P>0.05). There was no significant difference in the fracture healing time between the two groups ( P>0.05). At 3 months after operation, the early operation group exhibited superior Flynn elbow functional outcomes to the delayed operation group ( P<0.05). In the early operation group, there was 1 case of fracture non-union and 3 cases of cubital varus deformity after operation. In the delayed operation group, there was 1 case of nerve injury, 7 cases of fracture non-union, and 12 cases of cubital varus deformity after operation. There was significant difference in the incidence of complications between the two groups ( P<0.05). One case of the early operation group and 10 cases of the delayed operation group underwent secondary operation, showing no significant difference in the incidence of secondary operation between the two groups ( P>0.05).
CONCLUSION
For pediatric supracondylar humerus fractures, early closed reduction and percutaneous Kirschner wire fixation can reduce operation time, minimize intraoperative blood loss and postoperative complications, and improve the functional recovery compared to delayed operation.

OBJECTIVE:
To evaluate the effectiveness of Poster Fusion Cage combined with xenogeneic bone graft augmentation for bone defect management in distal radius fractures.
METHODS:
A retrospective analysis was conducted on 20 patients with bone defects complicating distal radius fractures who met the selection criteria and were treated between June 2022 and June 2024. The cohort comprised 2 males and 18 females, aged 54-87 years (mean, 63.3 years). Etiologies included falls in 17 cases, traffic accidents in 2 cases, and crush injury in 1 case. According to AO classification, there were 5 cases of type A, 8 cases of type B, and 7 cases of type C. The interval from injury to operation ranged from 2 to 10 days (mean, 5.8 days). All patients underwent volar plate fixation augmented with Poster Fusion Cage and demineralized xenogeneic bone matrix grafting. The operation time, intraoperative blood loss, fracture healing time, and postoperative complications were recorded. Radiographic parameters, including radial height, volar tilt, and ulnar deviation, were measured on standardized X-ray films obtained immediately postoperatively and at last follow-up, and whether secondary reduction loss occurred was judged. At last follow-up, wrist range of motion (extension, flexion, radial deviation, ulnar deviation, pronation, and supination) and grip strength (expressed as a percentage of the contralateral side) were measured. Wrist function was assessed using the Disabilities of the Arm, Shoulder, and Hand (DASH) score and Patient-Rated Wrist Evaluation (PRWE) score.
RESULTS:
The operation time was 70-200 minutes (mean, 116.4 minutes), and the intraoperative blood loss was 10-80 mL (mean, 36.5 mL). All surgical incisions healed by first intention, with no neurovascular complications documented. All patients were followed up 9-12 months (mean, 11.6 months). All fractures healed normally, with a healing time of 8-14 weeks (mean, 9.95 weeks). No significant difference was observed in radial height, volar tilt, or ulnar deviation between immediate postoperatively and last follow-up ( P>0.05). All fractures achieved satisfactory reduction, with no secondary loss of reduction or implant failure occurring during follow-up. At last follow-up, the range of motion of the affected wrist joint was 60°-65° (mean, 62.5°) in extension, 67°-75° (mean, 71.1°) in flexion, 18°-23° (mean, 20.4°) in radial deviation, 28°-33° (mean, 30.1°) in ulnar deviation, 69°-80° (mean, 74.7°) in pronation, and 69°-82° (mean, 75.6°) in supination. Grip strength recovered to 75%-85% (mean, 80%) of the contralateral side. Functional scores showed a DASH score of 5-15 (mean, 9.4) and PRWE score of 8.0-12.5 (mean, 10.2).
CONCLUSION
The combination of Poster Fusion Cage and xenogeneic bone graft augmentation provides a safe and effective treatment for bone defects in distal radius fractures.

OBJECTIVE:
To compare the effects of piriformis muscle release versus preservation in total hip arthroplasty (THA) via supercapsular percutaneously-assisted total hip (SuperPATH) approach on muscle injury.
METHODS:
Forty-nine patients undergoing initial THA via SuperPATH approach between June 2022 and June 2023 were randomly divided into two groups, with 24 patients in trial group and 25 patients in control group. The trial group received piriformis muscle release intraoperatively, whereas the control group underwent muscle preservation. There was no significant difference in baseline data such as gender, age, body mass index, disease type, American Society of Anesthesiologists (ASA) grading, and preoperative muscle infiltration, muscle atrophy, muscle injury serological indicators, Harris score, etc. ( P>0.05). The incision length, operation time, intraoperative blood loss, total blood loss, hospital stay, preoperative and postoperative 1-day muscle injury serological indicators [including creatine kinase (CK) and lactic dehydrogenase (LDH)], and incidence of complications between two groups were recorded. Harris score was used to evaluate the recovery of hip joint function. MRI was used to evaluate the extent of hip muscle injuries (gluteus minimus, gluteus medius, piriformis, obturator internus, quadratus femoris), including tendon integrity, degree of muscle fat infiltration, and degree of muscle atrophy preoperative and 1 year postoperatively.
RESULTS:
The operation time, intraoperative blood loss, and total blood loss in the trial group were significantly shorter than those in the control group ( P<0.05). There was no significant difference in the incision length and length of hospital stay between the two groups ( P>0.05). Both groups showed a significant increase in serum CK and LDH levels on postoperative day 1 compared to preoperative levels ( P<0.05), but there was no significant difference between the two groups ( P>0.05). All patients were followed up, the follow-up time for the trial group and the control group was (14.8±2.8) and (15.1±3.0) months, respectively, with no significant difference ( t=-0.400, P=0.691). Incisions healed by first intention in both groups, with 1 case in the trial group and 2 cases in the control group experiencing venous thrombosis in the calf muscle space. There was no complication such as deep vein thrombosis, pulmonary embolism, hip dislocation, prosthesis loosening, or periprosthetic infection in the lower limbs. There was no significant difference in the incidence of complications between the two groups ( P>0.05). At 1 year after operation, both groups of patients showed a significant increase in Harris scores compared to preoperative levels ( P<0.05), but there was no significant difference between the two groups ( P>0.05). Compared with preoperative results, both groups showed significant fat infiltration in the piriformis and obturator muscles at 1 year after operation ( P<0.05), while there was no significant fat infiltration in the gluteus minimus, gluteus medius, and quadratus femoris muscles ( P>0.05). At 1 year after operation, except for the higher incidence of piriformis muscle fat infiltration in the control group compared to the trial group ( P<0.05), there was no significant difference in the incidence of other muscle infiltrations between the two groups ( P>0.05). At 1 year after operation, both groups of piriformis and obturator muscles showed significant muscle atrophy compared to preoperative levels ( P<0.05). The gluteus minimus and gluteus medius showed mild atrophy compared to preoperative levels, while the maximum transverse diameter of the quadriceps muscle slightly increased, but the differences were not significant ( P>0.05). There was no significant difference in the maximum cross-sectional diameter or cross-sectional area changes of each muscle between the two groups ( P>0.05). At 1 year after operation, the continuity of the gluteus medius and quadratus femoris muscles in both groups was intact. Both groups had some patients with incomplete continuity of the piriformis muscle, obturator internus, and gluteus minimus, but the difference was not significant ( P>0.05).
CONCLUSION
The SuperPATH approach THA may cause injury to the piriformis, gluteus minimus, and obturator internus. The piriformis muscle release does not increase muscle injury, but it can shorten the operation time and reduce bleeding.

Chinese Journal of Reparative and Reconstructive Surgery 2025;39(7):896-902
OBJECTIVE:
To explore the application progress and clinical value of digital technologies in the surgical treatment of ankylosing spondylitis (AS).
METHODS:
By systematically reviewing domestic and international literature, the study summarized the specific application scenarios, operational procedures, and technical advantages of digital technologies [including preoperative three-dimensional (3D) planning, intraoperative real-time navigation, robot-assisted surgery, and 3D printing] in AS surgery, and analyzed their impact on surgical accuracy, complication rates, and clinical outcomes.
RESULTS:
Digital technologies significantly improve the precision and safety of AS surgery. Preoperative 3D planning enables personalized surgical protocols; intraoperative navigation systems dynamically adjusts surgical trajectories, reducing the risk of iatrogenic injury; robot-assisted surgery can minimize human errors and enhance implant positioning accuracy; 3D-printed anatomical models and guides optimize the correction of complex spinal deformities. Furthermore, the combined applications of these technologies shorten operative time, reduce intraoperative blood loss, decrease postoperative complications (e.g., infection, nerve injury), and accelerate functional recovery.
CONCLUSION
Through multidimensional integration and innovation, digital technologies provide a precise and minimally invasive solution for AS surgical treatment. Future research should focus on their synergy with biomaterials and intelligent algorithms to further refine surgical strategies and improve long-term prognosis.

Chinese Journal of Reparative and Reconstructive Surgery 2025;39(8):937-941
OBJECTIVE:
To summarize the research and clinical application progress of foot lengthening surgery.
METHODS:
Relevant research literature on foot lengthening surgery in recent years at home and abroad was reviewed, and a summary was made from aspects such as the types of lengthening surgery, the types of foot diseases treated by clinical application, effectiveness, and complications.
RESULTS:
Bone defects and shortening deformities of the foot are relatively common clinically. As an innovative treatment method, foot lengthening surgery has gradually attracted attention, mainly including the Ilizarov technique and one-stage bone grafting lengthening surgery. The former promotes bone regeneration based on the tension-stress principle and is widely used in the treatment of calcaneal defects and congenital metatarsal brachymetatarsia, achieving good curative effects. However, there are also complications such as pin-tract infection, joint stiffness and contracture, non-union and delayed union of bone, re-fracture, and alignment deviation. The latter has a short treatment cycle, but the lengthening length is limited. Bone graft resorption and soft tissue complications are its main complications.
CONCLUSION
Foot lengthening surgery will develop towards the direction of personalization, intelligence, and precision. With the help of multi-center research, biological materials, and intelligent technologies, the effectiveness and safety will be further improved to better restore the function and appearance of the foot.

OBJECTIVE:
To compare the effectiveness of clavicular hook plate fixation in the treatment of acromioclavicular joint dislocation and distal clavicle fractures.
METHODS:
A clinical data of 90 patients, who underwent clavicular hook plate fixation between January 2014 and June 2023, was retrospectively analyzed. There were 40 patients with distal clavicle fractures (fracture group) and 50 with acromioclavicular joint dislocations (dislocation group). There was no significant difference in the baseline data of gender, age, cause of injury, side of injury, time from injury to operation, and constituent ratio of osteoporosis patients between the two groups ( P>0.05). The time to remove the internal fixators and the occurrence of complications were recorded. Before removing the internal fixator and at 3 months after removing, the visual analogue scale (VAS) score was used to evaluate the degree of pain, and the mobility of the shoulder joint in forward flexion, elevation, and abduction was measured. Before removing the internal fixators, the Constant-Murley score and the University of California, Los Angeles (UCLA) score were used to evaluate the function of the shoulder joint. X-ray films of the shoulder joint were taken during follow-up to observe the occurrence of subacromial osteolysis, acromioclavicular joint osteoarthritis, and distal clavicle bone atrophy. Subgroup comparison was conducted between patients with and without subacromial osteolysis in the two groups.
RESULTS:
All incisions healed by first intention in both groups. All patients were followed up 1-9 years, with a median of 5 years; the difference in follow-up time between the two groups was not significant ( P>0.05). During follow-up, subacromial osteolysis occurred in 74 cases, including 41 cases of typeⅠand 33 cases of type Ⅱ, distal clavicle bone atrophy in 15 cases, and acromioclavicular joint osteoarthritis in 8 cases. There were significant differences in the removal time of internal fixators, the incidence of bone atrophy, and the incidence of osteoarthritis between the two groups ( P<0.05). There was no significant difference in the incidence of subacromial osteolysis ( P>0.05). Before removing the internal fixators, there was no significant difference in VAS score, UCLA score, and Constant-Murley score between the two groups ( P>0.05), while there were significant differences in shoulder joint range of motion in all directions ( P<0.05). After removing the internal fixators, only the difference in elevation was significant ( P<0.05). Within the group comparison, the VAS score and mobility of shoulder joint in abduction and elevation after removing the internal fixators were significantly superior to those before removing ( P<0.05). In the fracture and dislocation groups, there was only a significant difference in plate length between the subgroup with and without subacromial osteolysis ( P<0.05), while there was no significant difference in the above other indicators ( P>0.05).
CONCLUSION
Clavicular hook plate is a good choice for treating acromioclavicular dislocation or distal clavicle fractures, but the incidence of subacromial osteolysis is higher, and the degree of bone resorption is more severe in fracture patients. After removal of the internal fixator, the shoulder functions significantly improve. It is recommended to remove the internal fixator as soon as possible within the allowable range of the condition.
