One-stage vs two-stage bilateral THA in Lombardy: a cost-effectiveness analysis.

BACKGROUND: Total hip arthroplasty (THA) is the most common treatment for primary and secondary end-stage hip osteoarthritis (OA). Almost 20% of all patients undergoing primary THA suffer from bilateral hip OA and, consequently, will need a contralateral procedure to be performed in the following years. The aim of this study is to evaluate the cost-effectiveness and the reliability of one-stage bilateral THA (1-BTHA) compared to two-stage bilateral THA (2-BTHA), in low-risk patients, performed with anterior minimally invasive surgery (AMIS). METHODS: Single patient's costs were obtained by dividing the annual costs report by the number of hospitalizations, considering the diagnosis related group (DRG) of the two procedures. Then, 16 patients undergoing 1-BTHA and 8 undergoing 2-BTHA were examined. Hemoglobin (Hb) values before surgery and before discharge, transfusion rate and the occurrence of post-operative complications were observed. RESULTS: Procedural costs were divided in different subgroups: pre-hospitalization, operating room, hospital stay, post-operative follow-up and other costs. 1-BTHA total costs amount to 5.754,82€, while performing 2-BTHA costs 7.624,32€. However, considering DRG reimbursement, the hospital's profit margin following 1-BTHA is lower than that following 2-BTHA (6.346,18€ versus 9.261,68€). Surgical time was found not to be significantly different between 1-BTHA and 2-BTHA (141,13 ± 26,1 min vs 164,8 ± 44,3 min; p = 0,111). The two groups showed a statistically significant difference in Hb decrease (4,8 ± 1,3 g/dl vs 3,3 ± 0,9; p = 0,001), despite no variances in transfusion rate. No further complications were observed in either group. CONCLUSIONS: This study demonstrates how, in carefully selected patients, 1-BTHA performed with AMIS is a cost-effective and safe technique compared to 2-BTHA, resulting in a shorter OR time, LOS and lower overall costs.

Adolescent Idiopathic Scoliosis Surgery: Postoperative Functional Outcomes at 32 Years Mean Follow-Up.

INTRODUCTION: Recent clinical and radiographic studies conducted over short and medium terms have demonstrated positive results in patients undergoing surgery for adolescent idiopathic scoliosis (AIS). However, the absence of long-term data, crucial for comprehending the impact on future quality of life, especially in young patients actively involved in very intense physical activities, remains a gap. This study aims to evaluate long-term functional outcomes in patients who underwent surgery for Adolescent Idiopathic Scoliosis. MATERIAL AND METHODS: Patients meeting specific criteria (diagnosis of AIS, age at surgery between 12 and 18 years, and follow-up of at least 20 years) were identified from a large spine surgery center database. A questionnaire using "Google Form" assessed various outcomes, including Visual Analog Scale (VAS) back, VAS leg, Short Form 12 score (SF-12), Scoliosis Research Society 22 score (SRS-22), incidence of spine revision surgery, postoperative high demanding activities (work and sport), and possible pregnancies was sent to the enrolled patients. The authors analyzed the results regarding all patients included and, moreover, statistical analysis categorized patients into two groups based on the surgical fusion performed: Group 1 (non-instrumented technique according to Hibbs-Risser) and Group 2 (instrumented tecnique according to Cotrel-Dubousset). RESULTS: A total of 63 patients (mean age 47.5 years) were included, with a mean follow-up of 31.9 years. Patients were, in mean, 47.5 years old. Group 1 comprised 42 patients, and Group 2 had 21 patients. Revision surgery was required in 19% of patients, predominantly for implant issues in Group 2 (11.9% vs. 33%, p < 0.05). Overall outcomes were favorable: VAS back = 3.5, VAS leg = 2.5, SRS-22 = 3.5, SF-12 Physical Component Summary = 41.1, SF-12 Mental Component Summary = 46.7, with no significant differences between the group 1 and group 2. At 5-years FU, the non-reoperation rate was higher in the non-instrumented group (97.6% vs. 71.4%, p < 0.001). By means of SRS-22, overall satisfaction was 3.7 ± 1.2 on a maximum scale of 5. More than half of women have successfully completed one pregnancy. Most patients (87.3%) maintained regular work activity. Among sport practioners, half returned to the similar preoperative level. CONCLUSIONS: This study reveals favorable long-term functional results in adolescent idiopathic scoliosis patients after surgical fusion. Mild to moderate back and leg pain were observed, but overall satisfaction, sport participation, and work activity were high. Surgical technique (non-instrumented vs. instrumented) did not significantly impact long-term results, though the instrumented fusion exhibited a higher revision rate.

Clinical and functional evaluation of bone marrow aspirate concentrate vs autologous conditioned serum in the treatment of knee osteoarthritis.

BACKGROUND AND AIM: The aim of this study was to compare the efficacy of a single Bone Marrow Aspirate Concentrate (BMAC) with a cycle of 4 Autologous Conditioned Serum (ACS) injections in the treatment of early-stage knee osteoarthritis (OA). METHODS: Two groups of 12 patients with degenerative knee OA were treated with a single BMAC injection and with a cycle of 4 ACS injections respectively. Follow-up was set at baseline (t0), one-month (t1) and six-months (t2) evaluating VAS for pain, WOMAC index and range of motion (ROM). RESULTS: We reported a significant improvement in WOMAC after BMAC injection both at t1 (p= 0,001) as well as t2 (p< 0,001), plus a reduction of VAS values in BMAC group at six months follow-up (p = 0,024). In contrast, no significant differences in ROM between the two groups were observed. CONCLUSIONS: Both the approaches are safe and effective in the treatment of knee OA, with a major efficacy of BMAC.

Effect of Body Mass Index Percentile on Clinical and Radiographic Outcome and Risk of Complications after Posterior Instrumented Fusion for Adolescent Idiopathic Scoliosis: A Retrospective Cohort Study.

BACKGROUND: The aim of this study is to evaluate the effect of body mass index percentile (BMI%) at postoperative and medium follow-up in AIS patients undergoing posterior instrumented fusion (PSF). METHODS: We analyzed 87 clinical records of patients (19 male, 68 female) who underwent PSF. The patients were divided into four groups considering BMI%: underweight (UW), normal weight (NW), overweight (OW), and obesity (OB). Demographic, clinical (SRS-22), and radiographic data were collected. The primary outcome was to assess both the surgical and clinical outcomes, whilst the secondary outcome was to compare the radiological findings among the studied groups. Follow-ups were set preoperatively, at 6 months and 5 years. RESULTS: Our results did not show significant differences of clinical outcomes among the studied groups, except for a longer surgical time and a higher hemoglobin decrease in UW and OB patients (p = 0.007). All BMI categories showed similar radiographic outcomes, with no statistical significance at final follow-up. OB patients showed a worse percentage of major curve correction compared to baseline and to UW and OW patients. CONCLUSIONS: The present study does not underline substantial differences in clinical and radiographic results among any of the studied groups. However, UW and OB patients showed a worse postoperative progress. Counseling should be provided for patients and families and the achievement of a normal BMI% should be recommended.

The role of suction drainage in the management of peri-operative bleeding in Total and Unicomcompartmental knee arthroplasty: a retrospective comparative study.

BACKGROUND: Suction drainage is commonly applied after total knee arthroplasty (TKA) and unicompartmental knee arthroplasty (UKA) to reduce hematoma, swelling and to favor surgical wound healing. However, its efficacy remains controversial; thus, the purpose of this study is to evaluate drainage efficiency in the management of postoperative bleeding in TKA and UKA. METHODS: The cohort comprised 134 clinical records of patients affected by knee osteoarthritis (OA) who underwent either TKA or UKA. All the patients were subdivided into 2 groups: the first one with drainage and the second one without drainage (respectively 61 and 73 patients). For each group, hemoglobin levels in the preoperative, first, second and third postoperative day were collected. Postoperative complications such as swelling, bleeding from the surgical wound or the need for blood transfusion, were also recorded. RESULTS: Our results did not show any significant difference of hemoglobin levels in the first (p = 0.715), second (p = 0.203) and third post-operative day (p = 0.467) between the two groups. Moreover, no significant correlation between knee swelling or transfusion rate and the drainage was observed (p = 0.703 and p = 0.662 respectively). Besides, a significant correlation was found between bleeding from the surgical wound and the absence of drainage (p = 0.006). CONCLUSIONS: The study demonstrates how the routine use of suction drainage does not provide substantial benefits in the postoperative blood loss management after TKA or UKA.

Neglected acetabular fracture with hip dislocation in a 34-year-old subject treated with total hip arthroplasty: our experience.

Neglected hip fracture-dislocations are rare but still possible clinical situations, especially in developing countries. Some authors described skeletal traction and open reduction with internal fixation as a treatment for the abovementioned conditions. Despite the poor literature about this topic, total hip arthroplasty (THA) may be a feasible option in the treatment of neglected hip fracture-dislocations. We present a case of a 34-year-old Moroccan man reporting a 1-year neglected acetabular fracture with hip dislocation successfully treated with THA. The patient showed a significant improvement of pain, range of motion and his quality of life at 45 days. Our experience shows how a neglected acetabular fracture with hip dislocation can be successfully treated with THA. Considering the complexity of these cases, an accurate preoperative planning is mandatory and the prosthetic components' choice must be customised to the patient.

The efficacy of intra-articular HYADD4-G injection in the treatment of femoroacetabular impingement: results at one year follow up.

OBJECTIVE: Femoroacetabular impingement (FAI) is a condition that has been increasingly recognized as a source of hip pain and a possible risk factor to early development of hip osteoarthritis (OA). To our knowledge, the use of HA in the treatment of femoroacetabular FAI has been investigated only by two studies, both using a high molecular weight HA. The aim of this study was to evaluate the efficacy of two weekly injections of an hexadecylamide derivative of HA (HYADD4-G, HYMOVIS, Fidia Farmaceutici) in FAI. METHODS: All patients received two weekly intra-articular injections of Hymovis at baseline and after 7 days. Clinical and functional assessments were performed at baseline and was repeated after 1, 3, 6 and 12 months. Functional measures included visual analogue scale (VAS) for pain, Harris Hip score (HHS), Lequesne Index (LI), Tegner activity level scale (TALS) and monthly consumption of nonsteroidal anti-inflammatory drugs (NSAIDs). RESULTS: Twenty-one hips (19 patients, 2 bilateral cases) were treated. The variables VAS, HHS as well as Lequesne improved significantly from T0 to T4 (at 12 months) with the best improvement between T0 and T1. At the same time, a reduction in NSAIDs monthly intake was registered. On the other hand, a significant improvement in Tegner scale was not observed. No adverse events were registered. CONCLUSION: This study states that one cycle of HYADD4-G could be a safe and effective treatment in patients with FAI, showing significative results in term of pain control as well as hip functionality and quality of life up to 1 year.

Autologous conditioned serum: clinical and functional results using a novel disease modifying agent for the management of knee osteoarthritis.

Objective: The purpose of this study was to investigate the potential ability of autologous conditioned serum (ACS) to decrease pain and improve joint functionality in patients affected by knee osteoarthritis (OA). Methods: Fifteen patients with clinical and radiological signs of OA of the knee were recruited for this study. Each patient received 4 injections of ACS (Orthokine; orthogen, Dusseldorf, Germany) at the site of OA once per week for 4 weeks. Clinical and functional evaluation was performed using the VAS scale for pain, WOMAC scale and KSS functional and clinical scores before the first injection, at one week, at two weeks, at three weeks, at one month and at six months. Statistical analysis was done with the Wilcoxon Signed-Rank Test. Results: Our results show an improvement of all the evaluation scales at 6 months follow-up. Particularly, VAS scales among all patients decreased by 35.8% (p = .00148), KSS functional scores improved by 38.2% (p = .00148), KSS clinical scores improved by 28.9% (p = .00236) and WOMAC scores were reduced by 19.8% (p = .00188). Few adverse effects were observed in our sample. The most common complaint was pain and swelling in the subsequent days after performing the intra-articular injection. Only one patient reported rigidity following the injection of the ACS. Conclusion: Our results, in conjunction with preexisting studies in the medical literature regarding ACS, demonstrate the viability of this therapy for the treatment of knee OA, showing positive influence on pain and joint function without significant adverse effects.

The management of Salter-Harris type II fracture with associated posterior sternoclavicular joint displacement using a locking compression plate: A 14-year-old adolescent's case report.

RATIONALE: Posterior sternoclavicular joint dislocations (PSCJDs) are particularly rare injuries, accounting for 3% to 5% of sternoclavicular joint dislocations. With very few cases reported in the literature, these injuries are often misdiagnosed and imaging is not always clear, thus making physicians often unaware of them. The present case report aims to investigate a rare case involving a clavicular Salter-Harris II fracture with associated posterior displacement of the diaphysis, a term coined a "pseudodislocation." PATIENT CONCERNS: We present a case of a 14-year-old adolescent who sustained a traumatic injury to the shoulder while falling during a soccer match. His main concern was about recovery time and the return to daily life activities. DIAGNOSES: Multiple imaging studies imaging (X-rays, computed tomography, magnetic resonance imaging) revealed a Salter-Harris II fracture of the right clavicle with posterior displacement of the diaphysis. INTERVENTIONS: The patient underwent primary surgery to reduce the fracture, using an articular locking compression plate, and secondary surgery to remove the hardware. OUTCOMES: Following the removal of the hardware at 60 days after the initial surgery and a number of cycles of physiotherapy the patient reported a pain-free range of motion with slight limitation at extremes. Full return to recreational and everyday life activities were achieved at 3 months from the initial surgery. LESSONS: The PSCJDs are challenging injuries, as they are surrounded by delicate structures inside the mediastinum. Attention must be taken while diagnosing and treating these injuries as the risk of complications and iatrogenic injuries is high. To the author's knowledge, this case is one of the first of its kind described in the literature where we have a Salter-Harrys type II fracture associated with a posterior pseudodislocation of the lateral clavicle. Given the positive results of the case, we recommend the above-mentioned treatment protocol in PSCJD with associated Salter-Harris II fractures in adolescent patients.

Capsulectomy vs capsulotomy in total hip arthroplasty. Clinical outcomes and proprioception evaluation: Study protocol for a randomized, controlled, double blinded trial.

BACKGROUND: Patients affected by coxarthrosis may be treated surgically with total hip arthroplasty (THA). During the surgical intervention, the hip joint capsule can be completely removed, performing a capsulectomy. Otherwise it's possible to perform a capsulotomy, which allows for capsular conservation. Since there is no scientific evidence demonstrating the superiority of one method over the other, the choice whether to remove or conserve the capsule is at the surgeon's discretion and both procedures are actually accepted.The purpose of our study is to evaluate the differences in functional activities and proprioception in patients who underwent THA and capsulotomy with capsular conservation versus patients who underwent THA with capsulectomy. METHODS: In order to compare the two surgical techniques of capsulotomy with capsular conservation and capsulectomy, we created a randomized, controlled, double-blind, single-centre, non-pharmacological, interventional, superiority, parallel-group trial. The primary outcome of our study is evaluated using the HOOS scale (Hip disability and Osteoarthritis Outcome Score). Secondary outcomes are: the proprioceptive sensitivity, the postoperative bleeding, the surgical time, the active range of motion, and the ability to walk, sit and stand. The proprioception study is carried out through active and passive repositioning tests. THA is performed through the minimally invasive direct anterior approach. The evaluation tests are carried out in the 15 days preceding the intervention (T0), at 50-day post-operative (T1), and finally at three months after surgery (T2). DISCUSSION: Considering that the hip joint capsule is innervated by proprioceptive nerve endings, while the psuedocapsule that replaces the native capsule following a THA with capsulectomy doesn't have any active neurophysiological role, we hypothesize that capsulotomy with capsular conservation at the time of primary THA may lead to better proprioception and therefore better functional recovery.

ESWT and nutraceutical supplementation (Tendisulfur Forte) vs ESWT-only in the treatment of lateral epicondylitis, Achilles tendinopathy, and rotator cuff tendinopathy: a comparative study.

Objective: The purpose of this study was to determine the efficacy of Extracorporeal Shock Wave Therapy (ESWT) in combination with the dietary supplement Tendisulfur Forte in the treatment of shoulder tendinopathy, lateral epicondylitis, and Achilles tendinopathy. Methods: Patients were sub-divided for each pathology into two equal sized groups of 15: one treated with ESWT supplemented with Tendisulfur Forte, and the other treated with ESWT only. Shoulder functionality was measured through the UCLA shoulder score. Treatment of epicondylitis was assessed with the Mayo elbow score. Achilles tendinopathy was measured with the VISA-A score. Pain through the various groups of the study was measures with the Visual Analog Scale (VAS). Results: Patients in the Tendisulfur Forte group had overall better functional and VAS scale scores for shoulder tendinopathy, elbow epicondylitis, and Achilles tendinopathy. UCLA scores for shoulder tendinopathy showed significant results at 60 days in the Tendisulfur Forte group (p = 0.0002). Mayo scores in the treatment of lateral epicondylitis was significant at 60 days in the study group (p < 0.0001). Achilles tendinopathy was improved in the study group at 30 days (p < 0.0001). VAS scales were significant for each pathology at 60 days (p < 0.0001). In addition, NSAIDs consumption was greatly reduced and, in most cases, stopped in the Tendisulfur Forte Groups. Conclusion: Concerning the results obtained, this paper underlines the effectiveness of combined treatment of ESWT plus Tendisulfur Forte, in the absence of side-effects. Indeed, oral supplementation lead to a faster recovery and better outcomes with a significant reduction in NSAIDs consumption.

Bone Marrow Edema Syndrome of the Medial Femoral Condyle Treated With Extracorporeal Shock Wave Therapy: A Clinical and MRI Retrospective Comparative Study.

OBJECTIVE: To determine the validity of extracorporeal shock wave therapy (ESWT) in the treatment of bone marrow edema (BME) of the medial condyle of the knee. DESIGN: Retrospective. SETTING: Orthopedic Surgery outpatient clinic. PARTICIPANTS: Symptomatic patients (N=56) affected by BME of the medial condyle of the knee. Patients were equally divided into an ESWT-treated group and a control group, which was managed conservatively. INTERVENTIONS: ESWT delivery to the medial condyle of the affected knee. MAIN OUTCOME MEASURES: Clinical and functional assessment of the knee was performed with the use of the clinical and functional scores of the Knee Society Score (KSS). Pain was measured with the visual analog scale (VAS). BME area was measured with magnetic resonance imaging (MRI) before treatment and at 4 months' follow-up. RESULTS: Clinical evaluation of patients at final follow-up of 4 months posttreatment showed a significant improvement (P<.0001) of symptoms and knee functionality, both for range of motion and strength in both groups. VAS values were significantly improved (P<.0001) in both groups, with 3 patients in the ESWT group being pain-free (VAS=0) at 4 months' follow-up. At 4 months, MRI assessments on both sagittal and coronal views showed a significant reduction in BME in the ESWT group compared with the control group. CONCLUSIONS: Our findings show that ESWT is a valid nonpharmacologic and noninvasive therapy for spontaneous BME of the medial condyle that improves the affected vascular and metabolic state present in this pathologic disorder through its metabolic mechanisms of action.
