Objective. This current research is aimed at assessing clinical efficacy and prognosis of three-dimensional (3D) printing assisted patient-specific instrument (PSI) osteotomy guide in precise osteotomy of adult talipes equinovarus (ATE). Methods. We included a total of 27 patients of ATE malformation (including 12 males and 15 females) from June 2014 to June 2018 in the current research. The patients were divided into the routine group ( n = 12 ) and 3D printing group ( n = 15 ) based on different operative methods. The parameters, including the operative time, intraoperative blood loss, complications, time to obtain bony fusion, functional outcomes based on American Orthopedic Foot and Ankle Society (AOFAS), and International Congenital Clubfoot Study group (ICFSG) scoring systems between the two groups were observed and recorded regularly. Results. The 3D printing group exhibits superiorities in shorter operative time, less intraoperative blood loss, higher rate of excellent, and good outcomes presented by ICFSG score at last follow-up ( P < 0.001 , P < 0.001 , P = 0.019 ) than the routine group. However, there was no significant difference exhibited in the AOFAS score at the last follow-up and total rate of complications between the two groups ( P = 0.136 , P = 0.291 ). Conclusion. Operation assisted by 3D printing PSI osteotomy guide for correcting the ATE malformation is novel and feasible, which might be an effective method to polish up the precise osteotomy of ATE malformation and enhance the clinical efficacy.

Abstract Background: Obese patients are at risk of complications such as poor wound healing and increased infection rates after spinal surgery. Percutaneous endoscopic lumbar discectomy (PELD) has advantages over conventional open surgery in the treatment of obese adult patients with lumbar disc herniation (LDH) because it can decrease perioperative complications and enhance satisfaction degrees of patients. However, no clinical studies have evaluated the efficacy of PELD in obese adolescents with LDH. This study aimed to evaluate the efficacy of PELD in the treatment of obese ALDH.Methods: We retrospectively collected clinical data from 208 patients with single-segment ALDH who underwent PELD treatment in our hospital between January 2015 and December 2019. According to the body mass index classification standard of obesity for adolescents in our country, the patients were divided into obese and non-obese groups (control group). Based on the preoperative baseline data of the two groups, propensity score matching was performed to select patients from the two groups for the comparative study. Perioperative data included operative time, intraoperative blood loss and length of postoperative hospitalization. The visual analog scale (VAS), Oswestry disability index (ODI) and modified MacNab criteria were recorded as the main indicators of the surgical outcome, and the recurrence rate and incidence of complications were recorded as the minor indicators. Results: The obese and control groups included 45 patients each after 1:1 propensity score matching. Both groups showed improvements in VAS and ODI scores after surgery and at each follow-up time point (p < 0.05). However, there was no significant statistical difference in VAS and ODI scores between the two groups at each follow-up time point (p >0.05). In addition, the differences in operative time, intraoperative blood loss, length of postoperative hospitalization, incidence of complications, and recurrence rate were not statistically significant between the two groups (p >0.05). At the final follow-up, there was no significant difference in the excellent and good rate of MacNab classification between the two groups (p >0.05). Conclusion: PELD is a safe and effective minimally invasive technique for the treatment of obese patients with ALDH. The efficacy of PELD in obese and non-obese patients with ALDH was comparable.

Abstract Objective: To investigate the clinical efficacy of the MyoSure hysteroscopic tissue removal system in the treatment of benign intrauterine lesions. Methods: Retrospective analysis was performed on the clinical data of 740 patients treated with the MyoSure hysteroscopic tissue removal system for benign intrauterine lesions from September 2014 to December 2018, including 131 cases of submucosal myomas, 85 cases of endometrial polyps and 524 cases of RPOC. The clinical efficacy of MyoSure surgery was analyzed according to patients’ intraoperative conditions (intraoperative blood loss, operative time, lesion complete resection rate, and intraoperative complications) and postoperative symptom relief rate. Results: All 740 patients successfully completed the operation. The intraoperative blood loss was 17.09±14.87ml, 11.78±10.89ml and 29.50±13.74ml for submucosal myomas, endometrial polyps and RPOC, respectively, and the operative time was 42.37±19.33min, 20.96±8.99min and 30.47±14.04min, respectively. The complete resection rates (CRRs) of type 0, type Ⅰ and type Ⅱ lesions and mixed type fibroids were 100.0% (45/45), 96.00% (48/50), 85.67% (13/15) and 75.00% (9/12), respectively. For endometrial polyps and RPOC, the CRRs were 100% (85/85) and 98.28% (515/524), respectively. No intraoperative complications, such as uterine perforation, were reported with the exception of one patient with RPOC who exhibited TURP syndrome during the operation. The postoperative satisfaction rates for submucosal myomas, endometrial polyps and RPOC were 94.66% (124/131), 100.0% (85/85) and 98.85% (518/524), respectively. The conception rate was 47.91% (172/359), and the live birth rate was 59.30% (102/172). Conclusions: The MyoSure hysteroscopic tissue removal system is a safe and effective new treatment for benign intrauterine lesions for women of childbearing age.

Introduction Three-dimensional (3D) laparoscopy with a flexible camera was developed to overcome the main limitation of traditional laparoscopic surgery, which is two-dimensional (2D) vision. The aim of our article is to present the largest casistic of 3D laparoscopic radical prostatectomy (LRP) available in literature and evaluate our results in terms of pentafecta and compare it with the literature. Methods We retrospectively evaluated consecutive patients who underwent LRP with 3D technology between March 2014 and December 2015. Total operative time (TOT), anasthomosis time (AT), blood loss and complications were registered. All patients presented at least 3 months of follow-up. Surgical outcome was evaluated in terms of Pentafecta. Results One hundred fifty consecutive patients underwent 3D LRP. Mean follow-up was 16.9 months. Mean age was 67.7 ± 8.3 years (range 50-76). Mean preoperative PSA value was 8.3 ± 5.8 ng/ml and mean bioptic Gleason Score (GS) was 6.6. We had a mean TOT of 158 ± 23 minutes and a mean AT of 25 ± 12.6. Mean blood loss was 240 ± 40 ml. Eighteen (12%) postoperative complications occurred. Pathologic results: pT2 in 91 patients (58%) and pT3 in 59 (39.3%). Pentafecta was reached by 31.3% of patients at 3 months and 51.6% at 12 months. Conclusions Our oncological and functional results are comparable to those present in literature for laparoscopic and robotic surgery. We believe that our findings can encourage the use of 3D laparoscopy especially considering the increasing attention to healthcare costs.

Abstract Background The femoral neck system (FNS) may be a valid alternative for treating femoral neck fractures, but few studies have compared the outcomes between FNS and cannulated cancellous screws. This study aimed to compare the clinical efficacy and complications of FNS with those of inverted cannulated cancellous screws (ICCS) for the treatment of femoral neck fractures in adults. Methods This retrospective study evaluated patients with femoral neck fractures who underwent FNS or ICCS internal fixation between June 2019 and January 2020. The operative time, intraoperative blood loss, number of fluoroscopies, length of surgical incision, length of hospital stay, time to fracture healing, and other indicators were compared between the two groups. The incidence of complications such as nonunion, avascular necrosis of the femoral head, loosening of the internal fixation, and shortening of the femoral neck during follow-up was also assessed in both groups. Results Among the 92 patients included, 47 and 45 patients were categorized into the FNS and ICCS groups, respectively. Follow-up ranged from 14 to 24 months. There were no significant between-group differences in sex, age, side of the injured limb, and type of fracture and in operative time, intraoperative blood loss, incision length, and length of hospital stay (all P > 0.05). The incidence of complications such as fracture nonunion, avascular necrosis of the femoral head, and screw loosening was also comparable between the two groups. However, the number of fluoroscopies was significantly lower in the FNS group than in the ICCS group (P < 0.05). The fracture healing time was also significantly lower in the FNS group than in the ICCS group (P < 0.05). Furthermore, the femoral neck shortening and Harris hip score at the last follow-up were significantly better in the FNS group than in the ICCS group (P < 0.05). Conclusions FNS for femoral neck fractures improves hip functional recovery and reduces the femoral neck shortening rate and fluoroscopy exposure postoperatively. Thus, FNS can be an alternative to ICCS for the treatment of femoral neck fractures.

Abstract Background: Percutaneous vertebroplasty (PVP) and kyphoplasty (PKP) have been widely used to treat neurologically intact osteoporotic Kümmell’s disease (KD), but it is still unclear which treatment is more advantageous. Our study aimed to compare and investigate the safety and clinical efficacy of PVP and PKP in the treatment of KD.Methods: The relevant data that 64 patients of neurologically intact osteoporotic KD receiving PVP (30 patients) or PKP (34 patients) were analyzed. Surgical time, operation costs, intraoperative blood loss, volume of bone cement injection, and fluoroscopy times were compared. Occurrence of cement leakage, transient fever and re-fracture were recorded. Universal indicators of visual analogue scale (VAS) and Oswestry disability index (ODI) were evaluated separately before surgery and at 1 day, 6 months, 1 year, 2 years and the final follow-up after operation. The height of anterior edge of the affected vertebra and the Cobb’s angle were assessed by imaging. Results: All patients were followed up for at least 24 months. The volume of bone cement injection, intraoperative blood loss, occurrence of bone cement leakage, transient fever and re-fracture between two groups showed no significant difference. The surgical time, the operation cost and fluoroscopy times of the PKP group was significantly higher than that of the PVP group. The post-operative VAS, ODI scores, the height of the anterior edge of the injured vertebrae and kyphosis deformity were significantly improved in both groups compared with the pre-operation. The improvement of vertebral height and kyphosis deformity in PKP group was significantly better than that in the PVP group at every same time point during the follow-up periods, but the VAS and ODI scores between the two groups showed no significant difference.Conclusion: PVP and PKP can both significantly alleviate the pain of patients with KD and obtain good clinical efficacy and safety. By contrast, PKP can achieve better imaging height and kyphosis correction, and can be recommended as a preferred treatment options for KD.

Three-dimensional (3D) printing technology is increasingly being utilized in various surgical specialities. In paediatric orthopaedics it has been applied in the pre-operative and intra-operative stages, allowing complex deformities to be replicated and patient-specific instrumentation to be used. This systematic review analyses the literature on the effect of 3D printing on paediatric orthopaedic osteotomy outcomes. A systematic review of several databases was conducted according to PRISMA guidelines. Studies evaluating the use of 3D printing technology in orthopaedic osteotomy procedures in children (aged ≤ 16 years) were included. Spinal and bone tumour surgery were excluded. Data extracted included demographics, disease pathology, target bone, type of technology, imaging modality used, qualitative/quantitative outcomes and follow-up. Articles were further categorized as either ‘pre-operative’ or ‘intra-operative’ applications of the technology. Twenty-two articles fitting the inclusion criteria were included. The reported studies included 212 patients. There were five articles of level of evidence 3 and 17 level 4. A large variety of outcomes were reported with the most commonly used being operating time, fluoroscopic exposure and intra-operative blood loss. A significant difference in operative time, fluoroscopic exposure, blood loss and angular correction was found in the ‘intra-operative’ application group. No significant difference was found in the ‘pre-operative’ category. Despite a relatively low evidence base pool of studies, our aggregate data demonstrate a benefit of 3D printing technology in various deformity correction applications, especially when used in the ‘intra-operative’ setting. Further research including paediatric-specific core outcomes is required to determine the potential benefit of this novel addition. Cite this article: EFORT Open Rev 2021;6:130-138.

Primary Total Hip Arthroplasty

Introduction: Total hip arthroplasty (THA) is a well-established procedure for advanced arthritis of the hip joint. It significantly improves the quality of life by relieving pain and improving functional disability. The objective of this study was to evaluate the clinical and functional outcome of primary total hip arthroplasty using the Harris Hip Score. Method: Prospective study was conducted in Civil Service Hospital. Out of 145 THA performed from Jan 2014 to Dec 2018, the first 100 cases that fulfilled the inclusion criteria were analyzed.  Patient demographic and site, operative indication, and pre-operative Harris Hip Score was documented. Operative time, total intraoperative blood loss, and complications were noted. Patients were followed in 3 weeks, 6 weeks, 3 months, 6 months, and yearly. In each visit, clinical evaluation using Harris Hip Score and radiological evaluation was done and documented. The duration of follow up ranged from 12 months to 4.5 years. Results: Age varied from 21 to 75 years, 59% were male and 41% female, right side involvement was seen in 55% and left side in 45%. The major indication for surgery was avascular necrosis 46% and primary osteoarthritis in 24%. The average operative time was 65 minutes and the average intraoperative blood loss was 655 ml. Pre-operative Harris Hip Score ranged from 25 to 59 with a mean of 45.5. The mean Harris hip score in last follow up increased to 90.5 with a minimum of 76 and a maximum of 97. Our study found that 85% had excellent, 9% had good and 6% had fair results. Complications include 2% dislocation, 1% infection, 1% greater trochanter avulsion and 1% screw irritation. Conclusion: Primary THA is a safe and effective procedure. It improves pain and function hence improving the activity of daily living and has fewer complications.
