RESUMEN
BACKGROUND: Adamantinomas are rare malignant bone tumors. Due to their low incidence, there are few reports on the clinical results of adamantinoma. OBJECTIVES: This study aims to clarify outcomes in patients with adamantinoma using data from the National Bone and Soft Tissue Tumor Registry. METHODS: From 2006 to 2019, 38 cases of tibial origin were included. Twenty-four were male and 14 were female, with a mean age of 37 (6-87) years and a mean follow-up of 35 (1-128) months. RESULTS: Surgery was performed in 33 cases (87%) (curettage: 4 cases, wide resection: 27 cases, amputation: 2 cases). Reconstruction was performed in 27 patients who underwent wide resection. A total of 12 additional surgeries were performed in 11 patients. The main reason for the additional surgeries was nonunion of grafting bone in 6 cases. Oncologic outcomes were DOC (death from other causes) in one case and NED (no evidence of disease) in 37 cases. CONCLUSIONS: The results of treatment of adamantinomas in Japan have been extremely favorable. This may be due in part to the large number of cases with wide resection.

OBJECTIVE: This study focused on analyzing the clinical value and effect of magnetic resonance imaging plus computed tomography (MRCT) and CT in the clinical diagnosis of cerebral palsy in children. METHODS: From February 2021 to April 2023, 94 children diagnosed with cerebral palsy were selected from our hospital for study subjects. These patients were divided into CT and MRI groups, with CT examination given to the CT group and MRI examination given to the MRI group. The positive rate of the two examination methods in the diagnosis of cerebral palsy was compared, different imaging signs in two groups of children with cerebral palsy were compared, and the diagnostic test typing results between two groups were further analyzed. RESULTS: The diagnostic positivity rate of the children in the MRI group was 91.49%, which was significantly higher than that of the children in the CT group (70.21%) (P < 0.05). In both groups, encephalomalacia, bilateral frontal subdural effusions, and gray-white matter atrophy of the brain were the main signs, and the difference in the proportion of these three imaging signs between the two groups was not significant (P > 0.05). Differences between the two groups examined for cerebral palsy subtypes were not significant (P > 0.05). CONCLUSION: The positive rate of pediatric cerebral palsy examined by MRI is higher than that of CT diagnosis, but the clinic should organically combine the two to further improve the detection validity and accuracy.

PURPOSE: Malunited distal radius fractures frequently occur in the older population, posing a dilemma in selecting ideal management for symptomatic patients. Radial corrective osteotomy (RCO) and the Sauvé-Kapandji procedure (SK) have been used to treat this challenging condition. However, it remains unknown which approach is better for the older population. The objective of this study was to compare the outcomes of RCO with those of SK for the treatment of symptomatic distal radius malunion in older adults. METHODS: Thirty-three patients aged ≥60 years, with malunited distal radius fractures, were randomized to be treated with either RCO or SK and followed for a minimum of 2 years. The primary evaluation parameter was grip strength, and secondary outcome parameters were surgical time, range of motion of the wrist, exercise-related wrist pain assessment using visual analog scale scores, radiographic results, patient-reported outcomes evaluated using the Disability of the Arm, Shoulder, and Hand (DASH), and Patient-Related Wrist Evaluation (PRWE) scores. RESULTS: The average follow-up duration was 36.7 ± 10.2 months. The grip strength was significantly higher in the RCO group. The surgical time was shorter in the SK group than in the RCO group. The postoperative wrist range of motion and visual analog scale scores for exercise-related pain alleviation were similar in both groups. The ulnar variance decreased in both groups and was similar when compared with the postoperative images. The DASH and PRWE scores were similar between the RCO and SK groups. CONCLUSIONS: Radial corrective osteotomy and SK surgeries have similar clinical and functional outcomes in patients aged ≥60 years. Grip strength is higher in the RCO group than in the SK group. However, the operating time to accomplish SK is shorter than RCO. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic II.
RESUMEN
BACKGROUND: Long-term (minimum 19-year) outcome data on clinical results and patient satisfaction after posterior-stabilized total knee arthroplasties (TKAs) are missing in the literature. The purpose of the study was to evaluate the clinical and radiographic results as well as patient satisfaction at a mean of 21.2 years after posterior-stabilized TKAs. METHODS: This study included 756 patients (1,350 knees) who had undergone TKAs. There were 96 men and 660 women (mean age, 58 years; range, 40 to 84). The mean follow-up was 21.2 years (range, 19 to 23). At each follow-up visit, the patients were assessed radiographically and clinically. Furthermore, patient satisfaction was determined. RESULTS: The Knee Society total, pain, function, and deformity scores were 42, 18, 33, and 5 points, respectively, at the final follow-up. The mean Western Ontario and McMaster Universities Arthritis Index score was 25 points at the final follow-up. With revision or aseptic loosening as the end point, the 23-year intimated survival for the implant was 96% (95% confidence interval, 91 to 100%). The overall patient satisfaction score at the final follow-up was 83.3 points (range, 81 to 86). Patient satisfaction scores with regard to pain, housework, recreation, and surgery were 84, 81, 82, and 86 points, respectively. CONCLUSIONS: The findings of the present, mean 21-year follow-up clinical study suggest excellent results with regard to the revision rates and survivorship of the posterior-stabilized total knee implants. However, consistent with the literature, we found that about 80% of patients expressed overall satisfaction with their primary TKAs. About 8% of patients were either somewhat or very dissatisfied with the procedure.

PURPOSE: Condylar constrained knee prostheses (CCK) are increasingly used in revision total knee arthroplasty (rTKA), but the clinical effectiveness and long-term survival remain a debate. The purpose of this study is to report the long-term clinical and radiographic outcome, implant survival rate, and surgical safety of revision total knee arthroplasty with condylar constrained knee prosthesis. METHODS: A retrospective cohort study was performed on patients undergoing rTKA with CCK. The cases who received rTKA with CCK from January 2005 to January 2022 were selected. The duration of operation, the estimated perioperative blood loss, and the intraoperative blood transfusion rate were recorded to evaluate surgical safety. The pain visual analog scale (VAS), range of motion (ROM), the Hospital for Special Surgery (HSS) score, the Knee Society Score (KSS), the Western Ontario and McMaster University Osteoarthritis Index (WOMAC), and the Oxford knee score (OKS) was recorded to assess clinical outcome. Standard anteroposterior, lateral, skyline and long-standing AP radiographs of the lower limbs were conducted to assess radiographic outcome. Implant survival was analyzed by Kaplan-Meier survival estimates. RESULTS: Fifty-five cases were followed up for an average of 9.6 years (1-18 years), including 16 males and 38 females, with an average age of 66 and an average BMI of 26.9 kg/m2. The main reasons for revision were periprosthetic infection (32 knees, 58.2%) and aseptic loosening (13 knees, 23.6%). The duration of operation was 149 ± 56.2 min. The perioperative blood loss was 973.6 ± 421.6 ml. At the last follow-up, VAS (8.0 ± 1.1 to 1.3 ± 1.4), ROM (82.7° ± 26.1° to 108.4° ± 11.8°), HSS (45.0 ± 10.4 to 85.3 ± 8.6), KSKS (38.4 ± 12.1 to 88.5 ± 12.0), KSFS (19.6 ± 12.9 to 68.8 ± 15.1), WOMAC (67.9 ± 12.5 to 14.4 ± 9.5), and OKS (9.9 ± 4.2 to 41.6 ± 7.7) were significantly improved (P < 0.001). A total of five complications were observed, all of which were periprosthetic infection. Non-progressive radiolucent lines were observed in 26 knees (47.3%). The 10-year survival rate for no operation was 96.0%. The ten year survival rate for no revision was 98.0%. CONCLUSION: The use of CCK prosthesis for rTKA can achieve good long-term efficacy and prosthesis survival.

BACKGROUND: The value of double filtration plasmapheresis (DFPP) in severe hypertriglyceridemia-induced pancreatitis (sHTGP) is controversial. This study aimed to investigate the efficacy of DFPP on clinical outcomes in patients with sHTGP and the costs associated with the procedure. METHODS: Patients who underwent DFPP after admission between January 2016 and December 2021 were recruited. Data on lipid profile, clinical parameters, and costs were retrospectively collected and analyzed. RESULTS: Fifty sHTGP patients who received DFPP were enrolled. All of the lipid profile were significantly reduced and maintained a downward trend. The APACHE II score on admission was higher and the reduction after DFPP was more obvious (P < 0.05) in patients with higher triglyceride (TG) levels (≥33.9 mmol/L) than in patients with lower TG levels. More material fees were expended in the higher TG group due to more DFPP sessions (P < 0.05), but no significant differences existed in total hospital costs between the two groups. CONCLUSION: DFPP could rapidly and effectively reduce TGs to a safe level. APACHE II score reduction was obvious in patients with TGs ≥33.9 mmol/L and was associated with lipid profile changes. DFPP may benefit sHTGP patients with a TG level higher than the current initiation threshold.

OBJECTIVES: Clinical results of mobile-bearing total ankle arthroplasty (TAA) for rheumatoid arthritis (RA) have been reported, but no studies have compared osteoarthritis (OA) and RA. Clinical and radiographic outcomes after at least 3 years were compared between OA and RA. METHODS: Eleven ankles with OA and 22 ankles with RA were followed after mobile-bearing TAA (FINE total ankle system). Clinical outcomes were assessed by the American Orthopaedic Foot and Ankle Society (AOFAS) score. Radiographic outcomes were evaluated by the angular position of the implant, radiolucent lines, migration, and subsidence. Operative and postoperative complications were assessed. RESULTS: There were no significant differences in clinical outcomes, radiographic outcomes, or complications, except the final follow-up AOFAS total score (OA: 89.4 vs RA: 78.2; p = .044) and pain score (OA: 37.3 vs RA: 30.5; p = .041) at a mean follow-up of 83.4 months. Delayed wound healing occurred in 9.1% in RA and none in OA. Radiolucent lines were observed in 45% of both groups, and implant removal was performed in 9.1% and 18.2% of OA and RA, respectively; there were no significant differences. CONCLUSIONS: The final follow-up AOFAS total score and pain score were significantly higher in OA after the FINE total ankle system. There was a discrepancy between radiographic abnormalities and implant removal in both OA and RA.

There are few studies comparing clinical efficacy of decompression/fusion surgery (transforaminal lumbar interbody fusion (TLIF) + transpedicular interbody fusion) and minimally invasive microsurgical decompression (MMD) in patients with single-segment lumbar spinal stenosis. OBJECTIVE: To compare the results of TLIF + transpedicular interbody fusion and MMD in patients with single-segment lumbar spinal stenosis. MATERIAL AND METHODS: A retrospective observational cohort study included medical records of 196 patients (100 (51%) men, 96 (49%) women). Age of patients ranged from 18 to 84 years. Mean postoperative follow-up period was 20.1±6.7 months. Patients were divided into 2 groups: group I (control) included 100 patients who underwent TLIF + transpedicular interbody fusion, group II (study) included 96 patients who underwent MMD. We analyzed pain syndrome and working capacity using visual analogue scale (VAS) and Oswestry Disability Index (ODI), respectively. RESULTS: Analysis of pain syndrome in both groups after 3, 6, 9, 12 and 24 months clearly demonstrated stable relief of pain syndrome (VAS score) in the lower extremities. In group II, VAS score of lower back and leg pain was significantly higher in long-term follow-up period (after 9 months or more) compared to the 1st group (p<0.05). In long-term follow-up period (after 12 months), there was significant decrease in degree of disability (ODI score) in both groups (p<0.001) without between-group differences. We assessed achievement of treatment goal in 12 and 24 months after surgery in both groups. The result was significantly better in the 2nd group. At the same time, some respondents failed to achieve the final clinical goal of treatment in both groups (group I - 8 (12.1%), group II - 2 (3%) patients). CONCLUSION: Analysis of postoperative outcomes in patients with single-segment degenerative lumbar spinal stenosis revealed similar clinical effectiveness of TLIF + transpedicular interbody fusion and MMD regarding decompression quality. However, MMD was associated with less traumatization of paravertebral tissues, blood loss, fewer unwanted phenomena and earlier recovery.

Antisense technology is beginning to deliver on the broad promise of the technology. Ten RNA-targeted drugs including eight single-strand antisense drugs (ASOs) and two double-strand ASOs (siRNAs) have now been approved for commercial use, and the ASOs in phase 2/3 trials are innovative, delivered by multiple routes of administration and focused on both rare and common diseases. In fact, two ASOs are used in cardiovascular outcome studies and several others in very large trials. Interest in the technology continues to grow, and the field has been subject to a significant number of reviews. In this review, we focus on the molecular events that result in the effects observed and use recent clinical results involving several different ASOs to exemplify specific molecular mechanisms and specific issues. We conclude with the prospective on the technology.

OBJECTIVE: To compare the outcomes of open reduction and hook plate fixation (ORHPF) and modified TightRope loop plate fixation (MTRLPF) in the treatment of Rockwood type III acromioclavicular joint dislocation. METHODS: This was a retrospective study. Data on 71 patients with Rockwood type III acromioclavicular joint dislocation who underwent either ORHPF (n = 39) or MTRLPF (n = 32) between January 2016 and October 2019 were extracted and analyzed. Baseline data at injury were compared to evaluate the balance. The disabilities of the arm, shoulder, and hand (DASH) score, Constant-Murley score and visual analog scores (VAS) score at 1 month, 3 months, 6 months and 12 months after operation were compared; further, at 12 months coracoclavicular distance and related complications were evaluated and compared. RESULTS: Both groups did not differ for any baseline data. At 1 and 3 months after operation, MTRLPF group exhibited a significantly better performance than the ORHPF group in VAS (1 month: 2.4 ± 1.8 vs 3.0 ± 1.7; 3 months: 1.2 ± 1.4 vs 1.8 ± 1.6), Constant-Murley (1 month: 75.2 ± 11.2 vs 63.8 ± 13.7; 3 months: 81.4 ± 9.8 vs 75.8 ± 10.6), DASH (1 month: 33.6 ± 6.8 vs 40.6 ± 6.1; 3 months: 21.2 ± 7.4 vs 25.6 ± 6.6). At 6 months, only Constant-Murley remained marginally significant (p = 0.048). At 12 months, no statistical difference was observed for any outcome variable (all P > 0.05 for VAS, Constant-Murley and DASH), coracoclavicular distance (12.7 ± 1.6 mm vs 12.2 ± 1.6 mm; P = 0.374), or overall complication rate (P = 0.763). CONCLUSIONS: For Rockwood type III acromioclavicular joint dislocation, both methods can achieve satisfactory 1-year results, but modified minimally invasive TightRope treatment is more advantageous in early functional recovery at 1 and 3-month follow-ups.

BACKGROUND: The healing rate and tear pattern of grafts in superior capsular reconstruction (SCR) using acellular dermal matrix (ADM) allograft are poorly understood, and clinical results based on the graft status remain controversial. METHODS: Fifty-one consecutive patients undergoing arthroscopic SCR with ADM between October 2017 and February 2020 were enrolled. Range of motion, strength, and the visual analog scale pain (PVAS) score, American Shoulder and Elbow Surgeons (ASES) score, and Constant score were evaluated preoperatively and at the last follow-up. Postoperative magnetic resonance imaging was performed in all patients and was obtained at least 6 months (mean, 8.9 ± 3.6 months) after surgery. The graft tear status was analyzed on magnetic resonance imaging, and the numbers of patients who achieved the minimal clinically important difference and patient acceptable symptomatic state were analyzed to determine the differences in outcome according to graft tear status. RESULTS: The range of motion and clinical results improved at a minimum of 1 year (mean, 18 ± 5.4 months), whereas strength in forward flexion and external rotation did not (P = .676 and P = .995, respectively). The graft was intact in 36 of 51 patients (70.6%), 9 patients (17.6%) showed an incomplete graft tear with maintained continuity (partial graft rupture at 1 anchor on either the glenoid or humeral side), and 6 patients (11.8%) showed complete graft rupture (5 on the glenoid side and 1 on the humeral side). In cases with a tear (either incomplete or complete), the odds of achieving the minimal clinically important difference for the PVAS score (P = .047) and ASES score (P = .020) was significantly lower than that of the intact graft. However, when the continuity of the graft was maintained, even in cases with a partial tear, patients who reached the patient acceptable symptomatic state showed significantly higher odds for the PVAS score and trends for the ASES score. CONCLUSION: After SCR using ADM, the graft status could be classified as intact, an incomplete graft tear (where the continuity between the glenoid and humerus was maintained), or an complete tear. When the graft continuity was maintained, even in incomplete graft tears, patients were generally satisfied with postoperative pain and function at 1 year following SCR.

BACKGROUND: To insert the regular-sized stem for a dysplastic femoral canal, controlled episiotomy of the femur can be performed. The purpose of this study is to determine the long-term (up to 19 years) results of total hip arthroplasties (THAs) using strut allografts combined with an episiotomy over an extensively porous-coated stem. METHODS: We reviewed the results of 65 total hip arthroplasties in 63 patients (mean age 42.1 years; range 21-61) with dysplastic femur after childhood sepsis. The patients were treated using controlled episiotomy of the femur to widen the femoral canal, extensively porous-coated femoral stems, and cortical strut allografts because primary axial or rotational stability could not be achieved without grafting. The mean follow-up was 17.1 years (range 15-19). RESULTS: The mean Harris Hip Score at the final follow-up was 85 ± 15 points (range 45-100). The mean Western Ontario and McMaster Universities Osteoarthritis Index score was 23 ± 15 points (range 13-53). The mean University of California, Los Angeles score was 6.3 points (range 5-8). A Kaplan-Meier survivorship analysis at 19 years of follow-up showed that the survival rate of the femoral components was 92% (95% confidence interval 89-98), and it was 88% (95% confidence interval 85-92) for the acetabular component with aseptic loosening or revision for any reason. CONCLUSION: We found good results in terms of longevity and functional outcome using this technique. Future mechanical studies, in addition to controlled clinical studies, are warranted.

Longitudinal plantar approaches are generally considered at risk for wound healing problems. Thus, we wanted to investigate long-term outcomes after a primary Morton's neuroma excision through a longitudinal plantar approach. A retrospective study of patients with primary neuroma excision was conducted. Twenty-four patients (28 feet) were evaluated at a mean 9-year follow-up (range, 6-14) by a single trained examiner using a specific postoperative evaluation protocol, including AOFAS Forefoot subjective and objective scores. Good-to-excellent outcomes were reported in 25 (89.3%) cases. A hypertrophic scar formation and keratosis occurred in only 2 cases (7.1%). All the patients, with a single exception, achieved full weightbearing with a postoperative shoe from the first day after the operation. A longitudinal plantar approach can lead to long-term, good-to-excellent outcomes with no case of recurrence or reoperation. Accurate wound closure and immediate weightbearing with a postoperative shoe can minimize the rate of complications. This approach should be considered for primary resection of Morton's neuromas.
RESUMEN
PURPOSE: This study evaluated the clinical and radiological results of plate osteosynthesis with autologous cortical and cancellous bone graft for nonunion of midshaft clavicle fracture. METHODS: A retrospective review was performed for all patients who underwent surgery for midshaft clavicle nonunion at a Level I trauma center. Visual analog scales (VAS) for pain and Quick-DASH (Disabilities of Arm, Shoulder, and Hand) score were assessed. Bone union rate, change in length of affected clavicle, complications, and reoperation were determined. Risk factors were identified to determine the effect on the healing. RESULTS: Thirty-four patients were included for analysis. All patients achieved solid bone union at mean 16 weeks (range 8-36) after surgery. The mean shortening of affected clavicle decreased significantly postoperatively (P < 0.001). There was significant improvement in both pain VAS and Quick-DASH score (P < 0.001). There was no wound complication, infection, or major neurovascular injury. Ten patients (29%) complained of plate irritation and underwent removal of implant without any subsequent adverse event. Multiple regression analysis demonstrated that high-energy trauma and previous surgery were the independent risk factors that significantly delayed time to union (P < 0.05). CONCLUSION: Osteosynthesis with autologous dual bone graft for nonunion of midshaft clavicle produced an excellent union rate with good clinical outcome and minimal complications.

OBJECTIVE: To study the risk factors of unsatisfactory clinical results after percutaneous laser decompression of the lumbar intervertebral disc (PLDD). MATERIAL AND METHODS: A retrospective observational single-center study included medical records of patients who underwent lumbar PLDD for degenerative spine disease. We analyzed clinical and instrumental parameters potentially affecting the results of lumbar PLDD. RESULTS: Clinical study included 82 patients who underwent PLDD for lumbar intervertebral disc degenerative disease. Mean postoperative follow-up period was 30.8±13.3 months. In 22 (26%) patients, unsatisfactory clinical outcomes were observed. According to binary logistic regression model, comorbidities (p=0.03), duration of disease over 12 months (p=0.03), low preoperative quality of life according to ODI score (more than 50%) (p=0.04), high body mass index (over 25 kg/m2) (p=0.02), severe intervertebral disc (p=0.04) and facet joint degeneration (p=0.01) and intervertebral disc height decrease more than 50% (p=0.01) were significantly associated with unsatisfactory clinical outcomes after lumbar PLDD for degenerative spine disease. CONCLUSION: Identification of these risk factors of unsatisfactory clinical outcomes is important stage of preoperative preparation in patients scheduled for lumbar PLDD.

BACKGROUND: The purpose of this study is to determine the long-term (up to 27 years) results of a modified technique applying strut allografts combined with a reduction osteotomy over an extensively porous-coated stem. METHODS: We reviewed the results of 399 revision total hip arthroplasties (for aseptic loosening in 390 hips and septic loosening in 9 hips) in 369 patients (mean age 58 ± 13 years, range 22-65) performed with an extensively porous-coated femoral stem combined with a cortical strut onlay allograft. The mean follow-up was 23 years (range 20-27). RESULTS: The mean Harris Hip Score was 84 ± 16 points (range 35-100) at the final follow-up. The mean Western Ontario and McMaster Universities Osteoarthritis Index score was 21 ± 16 points (range 12-53) at the final follow-up. The mean University of California Los Angeles activity score was 6.1 points (range 5-8). A Kaplan-Meier survivorship analysis at 23 years of follow-up showed that the survival rate of the femoral component was 95.5% (95% confidence interval 89-98) with aseptic loosening or revision for any reason and it was 91.5% (95% confidence interval 85-95) if septic loosening was included. CONCLUSION: We found good results in terms of longevity and functional outcome using this modified technique. Future mechanical studies in addition to controlled clinical studies are warranted.

BACKGROUND: The purpose of this study is to compare the long-term clinical and radiographic results, survival rates, and complication rates of an ultra-short vs a conventional length cementless anatomic femoral stem. METHODS: We reviewed 759 patients (858 hips) (mean age, 56.3 ± 12.9 y) who had an ultra-short cementless anatomic stem and 759 patients (858 hips) (mean age, 54.8 ± 12.3 y) who had a conventional length cementless anatomic stem. The mean follow-up was 16.5 years (range 14-17) in the ultra-short stem group and 17.5 years (range 17-20) in the conventional stem group. RESULTS: At the latest follow-up, there were no significant differences between the 2 groups in terms of the Harris Hip Scores (92 ± 6 vs 91 ± 7 points, P = .173), Western Ontario and McMaster Universities Osteoarthritis scores (12 ± 8 vs 13 ± 7 points, P = .972), University of California Los Angeles activity scores (7.6 vs 7.8 points, P = .841), patient satisfaction scores (7.7 ± 2.3 vs 7.5 ± 2.5 points, P = .981), and survival rates (97.6% vs 96.6%). However, incidence of thigh pain (P = .031) and stress shielding (P = .001) was significantly higher in the conventional length stem group than in the ultra-short anatomic stem group. Complication rates were similar (1.8% vs 2.7%) between the 2 groups. CONCLUSION: Although an ultra-short cementless anatomic femoral stem confers equivalent clinical and radiographic outcomes, survival rates, and complication rates to conventional length cementless anatomic stem, the incidence of thigh pain and stress shielding was significantly lower in the ultra-short cementless anatomic stem.

PURPOSE: Recurrent lumbar disc herniation is the most common complication after discectomy. Due to the altered anatomy with the presence of scar tissue, the surgical revision of already operated patients could be a surgical challenge. METHODS: We describe the microsurgical revision technique step by step with the evaluation of our own clinical results in comparison with primary lumbar disc surgeries. The clinical data are based on a clinical register with 2576 recorded primary surgeries (PD) and 592 cases of revisions (RD) with 12- and 24-month follow-up (FU). The intraoperative dura lesion rates of the surgeries between 2016 and 2018 were recorded retrospectively. Data from 894 primary disc surgeries and 117 revisions were evaluated. RESULTS: The ODI and the VAS for leg and back pain improved in both groups significantly with slightly inferior outcome of the revision group. The ODI improved from 46.3 (PD) and 45.9 (RD), respectively, to 12.6 (PD) and 22.9 (RD) at the 24-month FU. The VAS dropped down as well in both group [VAS back: 47.8 (PD) and 43.9 (RD) to 19.9 and 32.2 at the 24-month FU; VAS leg: 62.9 (PD) and 65.5 (RD) to 15.6 and 26.8 at the 24-month FU]. During the primary interventions, we observed 1.5% (11/894) and during revisions 7.7% (9/117) of dura lesions. CONCLUSIONS: There is no clear guideline for the surgical treatment of recurrent disc herniations. In most cases, a pure re-discectomy is sufficient and can be performed safely and effectively with the help of a microscope. These slides can be retrieved under Electronic Supplementary Material.

BACKGROUND: To investigate the effects of platelet-rich plasma (PRP)-incorporated autologous granular bone grafts for treatment in the precollapse stages (Association of Research Circulation Osseous stage II-III) of posttraumatic osteonecrosis of the femoral head. METHODS: A total of 46 patients were eligible and enrolled in the study. Twenty-four patients were treated with core decompression and PRP-incorporated autologous granular bone grafting (treatment group), and 22 patients were treated with core decompression and autologous granular bone grafting (control group). During a minimum follow-up duration of 36 months, X-ray and computed tomography were used to evaluate the radiological results, and the Harris hip score (HHS) and visual analog scale were chosen to assess the clinical results. RESULTS: Both the treatment and control groups had a significantly improved HHS (P < .001). The minimum clinically important difference for the HHS was reached in 91.7% of the treatment group and 68.2% of the control group (P < .05). The HHS and visual analog scale in the treatment group were significantly improved than that in the control group at the last follow-up (P < .05). Successful clinical and radiological results were achieved 87.5% and 79.2% in the treatment group compared with 59.1% and 50.0% in the control group (P < .05), respectively. The survival rates based on the requirement for further hip surgery as an endpoint were higher in the treatment group in comparison to those in the control group (P < .05). CONCLUSION: PRP-incorporated autologous granular bone grafting is a safe and effective procedure for treatment in the precollapse stages (Association of Research Circulation Osseous stage II-III) of posttraumatic osteonecrosis of the femoral head.

The mechanical superiority of suture tape augmentation associated with the Broström-Gould procedure for treating lateral ankle instability has been reported. This study aimed to describe functional results using the visual analog scale (VAS), American Orthopedic Foot & Ankle Society (AOFAS) scale, and Short Form of Quality of Life Survey (SF-36) in patients with ankle lateral instability who underwent the modified Broström-Gould repair and suture tape augmentation and to determine the recurrence of injury and the impact on the perception of its stability. This retrospective cohort study included patients with lateral ankle instability treated using the modified Broström-Gould procedure and suture tape augmentation from December 2015 to July 2018 with a 6- to 36-month follow-up. Clinical and functional results were evaluated using the 3 aforementioned scales. p ≤ 0.05 was considered statistically significant. Twenty-eight patients were included, 18 (64%) males and 10 (36%) females (mean ± standard deviation age of 33.25 ± 12.73). The mean pre- and postoperative VAS scores were 6 ± 1.18 and 0.53 ± 0.92, respectively. The average pre- and postoperative AOFAS scores were 65.89 ± 15.08 and 94.60 ± 6.88, respectively; results were excellent (91 to 100) in 18 (64%) patients and good (81 to 90) in 10 (36%). Three patients experienced recurrence of injury treated with physical therapy, and their progress was satisfactory; stability perception was maintained. Excellent clinical and functional results were demonstrated in our study using suture tape augmentation in the modified Broström-Gould procedure, which probably protects against the recurrence of lateral ankle instability.
