Comparison between Malerba osteotomy and combined Evans/medial displacement calcaneal osteotomies for the management of flexible pes planus in young adults: a prospective randomised control trial, three years follow-up.

PURPOSE: The aim of the current study is to evaluate the functional and radiological outcomes of Malerba osteotomy in comparison to the standardized combined Evans/Medial Displacement Calcaneal Osteotomy (MDCO) in the management of symptomatic flexible pes planus in young adults. METHODS: Prospective randomized control trial included 34 feet (33 patients), 17 cases in each group. Functionally, patients were assessed by AOFAS and FADI scores. Radiographic evaluation included calcaneal pitch, lateral talo-1st metatarsal, AP talo-first metatarsal, AP talo-calcaneal angles, and the talar coverage percentage. RESULTS: Pre-operative and three years follow-up scores and angles were compared between both groups. No statistically significant difference could be detected between both groups (P value 0.87). However, the data showed statistically significant difference in each group when comparing (pre-operative and third year follow-up scores and angles) (P value < 0.001). The mean union rate was eight weeks in Malerba group and nine weeks in Evans/MDCO group. No incidence of nonunion. Complications like calcaneocuboid subluxation, calcaneal anterior process fracture, and lateral column pain were exclusively reported in Evans/MDCO group. CONCLUSION: Malerba osteotomy is a strong valid option for the operative management of flexible pes planus in young adults. Authors recommend Malerba osteotomy in all mild and moderate deformities due to lower complication rate while the combined Evans/MDCO is preferred in severe deformity due to relatively higher corrective power with consideration of possible complications.

Increased Risk of Valvular Heart Disease in Systemic Sclerosis: An Underrecognized Cardiac Complication.

OBJECTIVE: Cardiac involvement is a poor prognostic marker in systemic sclerosis (SSc). While diastolic dysfunction, myocardial fibrosis, and arrhythmias are traditionally considered features of primary cardiac involvement in SSc, the incidence of valvular heart disease (VHD) is not well reported. Our objective was to examine the prevalence of VHD at the time of SSc diagnosis and incidence of VHD during follow-up compared to non-SSc subjects. METHODS: Medical records of patients with suspicion of SSc were reviewed to identify incident cases. SSc subjects were matched 1:2 by age and sex to non-SSc subjects. RESULTS: The study included 78 incident SSc cases and 156 non-SSc comparators (56 yrs [± 15.7], 91% female). A nearly 4-fold increase in the prevalence of moderate/severe VHD prior to SSc diagnosis compared to non-SSc subjects (6% vs 0%; P = 0.004) was identified. During follow-up, 18 SSc and 12 non-SSc patients developed moderate/severe VHD. The cumulative incidence of VHD at 10 years after SSc incidence/index was 17.9% (95% CI 10.7-29.9) in patients with SSc compared with 2.3% (95% CI 0.7-7.0) in non-SSc subjects (HR 4.23, 95% CI 2.03-8.83). Coronary artery disease was the only significant risk factor for VHD. CONCLUSION: Patients with SSc have a 4-fold increase in the prevalence of moderate/severe VHD at diagnosis compared to non-SSc patients. They also have a 4-fold increased risk of developing moderate/severe VHD after diagnosis of SSc. Aortic stenosis and mitral regurgitation have a much higher prevalence in patients with SSc, besides secondary tricuspid regurgitation. Underlying mechanisms for this association require further elucidation.

Epidemiology and Trends in Survival of Systemic Sclerosis in Olmsted County (1980-2018): A Population-based Study.

Background/Purpose: To update the epidemiology of systemic sclerosis (SSc) and evaluate the performance of the ACR/EULAR 2013 vs. 1980 ARA classification criteria in a U.S. population-based cohort. Methods: An inception cohort of patients with incident SSc from January 1, 1980, through December 31, 2018, in Olmsted County, Minnesota, was identified based on comprehensive individual medical record review. Incidence and prevalence rates were age- and sex-adjusted to the 2010 US white population. Survival rates were compared with expected rates in the general population. Fulfillment of 1980 and 2013 classification criteria was ascertained. Results: A total of 85 incident cases of SSc (91% female, mean age 55.4 ± 16 y) and 49 prevalent cases on Jan 1, 2015 were identified. The overall age- and sex-adjusted annual incidence was 25 (95% CI 20-31) per million population, with no change in incidence over time. The age- and sex-adjusted prevalence was 436 (95% CI: 313-558) per 1,000,000 population. 77 (91%) patients fulfilled the 2013 classification criteria, and 38 (45%) fulfilled the 1980 criteria. Mortality among patients with SSc was significantly higher in comparison to the general population, with a standardized mortality ratio of 2.48 (95% CI:1.76-3.39) and no evidence of improvement over time. Conclusions: SSc developed in 25 persons/million/year with no change over the 39-year study period. The 2013 classification criteria perform significantly better than the 1980 criteria but failed to classify 9% of patients. SSc portends a 2.5-fold higher risk of mortality than the general population, with no evidence of improved survival over time.

Systemic Sclerosis Portends Increased Risk of Conduction and Rhythm Abnormalities at Diagnosis and During Disease Course: A US Population-Based Cohort.

Objectives: To study the incidence, risk factors and outcomes of conduction and rhythm disorders in a population-based cohort of patients with systemic sclerosis (SSc) vs. non-SSc comparators. Methods: An incident cohort of patients with SSc (1980-2016) from Olmsted County, MN was compared to age- and sex-matched non-SSc subjects (1:2). Electrocardiograms (ECGs), Holter ECGs, and need for cardiac interventions were reviewed to determine the occurrence of any conduction or rhythm abnormalities. Results: 78 incident SSc cases and 156 comparators were identified (mean age 56 y, 91% female). The prevalence of any conduction disorder prior to SSc diagnosis compared to non-SSc subjects was 15% vs. 7% (p=0.06), and any rhythm disorder was 18% vs. 13% (p=0.33). During a median follow-up of 10.5 years in patients with SSc and 13.0 years in non-SSc comparators, conduction disorders developed in 25 patients with SSc with cumulative incidence of 20.5% (95% CI: 12.4-34.1%) vs. 28 non-SSc patients with cumulative incidence of 10.4% (95% CI: 6.2-17.4%) (HR: 2.57; 95% CI: 1.48-4.45), while rhythm disorders developed in 27 patients with SSc with cumulative incidence of 27.3% (95% CI: 17.9-41.6%) vs. 43 non-SSc patients with cumulative incidence of 18.0% (95% CI: 12.3-26.4%) (HR: 1.62; 95% CI: 1.00-2.64). Age, pulmonary hypertension and smoking were identified as risk factors. Conclusion: Patients with SSc have an increased risk of conduction and rhythm disorders both at disease onset and over time, compared to non-SSc patients. These findings warrant increased vigilance and screening for ECG abnormalities in SSc patients with pulmonary hypertension.

Short-segment fixation through a limited ilioinguinal approach for treating anterior acetabular fractures: a historical-control study.

PURPOSE: We evaluated the potential advantages of short-segment fixation of certain anterior acetabular fracture patterns through a limited ilioinguinal approach. METHODS: Two patient groups were studied. The first group comprised 22 patients (20 men, two women; average age 36 years) treated using the short-segment fixation protocol through a limited ilioinguinal approach. We modified the use of short pelvic brim plates, spring plates and posterior-column screws as reduction and fixation tools (leaving the distal end of the fracture unfixed) to keep the dissection entirely lateral to the iliac vessels. The second (control) group comprised 31 patients with matched fracture patterns fixed through the standard ilioinguinal approach. All patients were followed up for a minimum of two years. The estimated amount of blood loss (primary outcome measure), operative time, postoperative radiographic assessment of reduction quality and functional score assessment (secondary outcome measures) were compared between groups. RESULTS: The short-segment-fixation group had significantly less blood loss (p < 0.0001) and shorter operative time (p = 0.002) compared with the control group. However, there were no significant differences in the quality of fracture reduction and functional scores between groups at the final follow-up. No major complications were encountered in either group. CONCLUSION: Short-segment fixation through a limited ilioinguinal approach is a safe and effective alternative for treating certain patterns of anterior acetabular fractures. Decreased blood loss and shorter operative time with less soft tissue dissection are the main advantages of this approach.

Multiple arthroscopic debridement and graft retention in septic knee arthritis after ACL reconstruction: a prospective case-control study.

PURPOSE: This study was undertaken to prospectively analyse, at a mean five-year follow-up, the clinical, functional, and radiographic outcomes in patients who developed postoperative acute septic knee arthritis following anterior cruciate ligament (ACL) reconstruction using hamstring autograft. We also assessed the effect of multiple arthroscopic debridement and graft retention on the functional outcomes in comparison with the matched control group. METHODS: From a consecutive case series of 2,560 ACL-injured patients who were treated with arthroscopic ACL reconstruction, we report on 24 cases with postoperative septic knee arthritis. These patients were individually matched for age, sex, comorbidity, body mass index (BMI) and preinjury Tegner activity scale in a ratio of 1/1. Clinical, laboratory, synovial fluid analysis and culture were performed. Arthroscopic debridement and graft retention was done for all cases, in addition to antibiotic therapy i.v.. A detailed physical examination, KT1000 laxity testing, Lysholm knee score, Tegner activity level scale, International Knee Documentation Committee (IKDC), and Knee Injury and Osteoarthritis Outcome Score (KOOS) were completed. RESULTS: In all cases, treatment of infection was successful after a median of three (range one to six) repeated arthroscopic graft debridement and retention, in addition to antibiotic therapy i.v.. At an average of five years follow-up, two patients had over five millimetres manual maximum side-to-side difference in laxity. There were no significant differences between groups regarding Lysholm score, IKDC and KOOS. Median final Tegner activity score was 5.5 versus 7 in the control group (p = 0.004). Complications included graft rupture in three patients, loss of range of motion in five, Sudeck's atrophy in one and moderate joint narrowing in two. There were no recurrences of septic arthritis or bone infection. CONCLUSION: Graft retention seems not only possible but appropriate in view of the experience presented in this article for postoperative septic knee arthritis using hamstring autograft. A potential residual complication is arthrofibrosis, which deserves maximum attention.

Analgesic effect of intra-articular magnesium sulphate compared with bupivacaine after knee arthroscopic menisectomy.

This work aimed to evaluate the analgesic efficacy of intra-articular injection of magnesium sulphate (4%) compared with equivalent volume of bupivacaine (0.5%) after outpatient knee arthroscopic meniscectomy. Forty patients were randomly assigned to two groups. Group M (n = 20) received intra-articular magnesium sulphate 4%, group B (n = 20) received bupivacaine (0.5%). Analgesic effect was evaluated by analgesic duration, and by measuring pain intensity at 1, 2, 4, 6, 12, 24 h both at rest and on knee movement to 90°. The primary outcome variable was pain intensity on the VAS at 1, 2, 4, 6, 12, 24 h post arthroscopy at rest and on movement (flexion of knee to 90°), although the magnesium group had lower time weighted averages (TWAs) at rest and on movement, these TWAs were not statistically significant. The median duration of postoperative analgesia was significantly longer in the patients treated with magnesium sulphate (528 min) than in the bupivacaine group (317 min) (p < 0.0001), with less number of patients needing supplementary analgesia in magnesium group (8/20) than those of the bupivacaine group (16/20) (p < 0.022). Also analgesic consumption was significantly lower in the magnesium sulphate group (p < 0.002). We concluded that the use of magnesium sulphate is rational and effective in reducing pain, and is more physiological and shortens convalescence after outpatient arthroscopic meniscectomy, however our hypotheses that analgesic efficacy of intra-articular isotonic magnesium sulphate would be superior to intra-articular local anaesthetic cannot be supported with this study.

Percutaneous distal metatarsal osteotomy versus distal chevron osteotomy for correction of mild-to-moderate hallux valgus deformity.

PURPOSE: A lot of procedures were described for managing hallux valgus deformity. Percutaneous metatarsal osteotomies have received increasing recognition in the previous decade. The proposed benefits revolve primarily around the shorter surgical time, lower incidence of complications, and higher patient satisfaction. However, there is insufficient evidence to determine whether this technique is comparable to traditional open approaches. MATERIALS AND METHODS: A total of 64 consecutive feet (53 patients) with mild-to-moderate symptomatic hallux valgus were randomly assigned into two groups to compare the results of percutaneous distal metatarsal osteotomy (group I, 31 feet) and distal chevron osteotomy (group II, 33 feet). All patients were clinically assessed using the American Orthopedic Foot and Ankle Society (AOFAS) scoring system. Radiographical assessment was done using the hallux valgus angle (HVA) and intermetatarsal angle (IMA). RESULTS: The mean correction of HVA and IMA achieved in group I was 14.4° and 4.8°, respectively, while in group II, it was 13.1° and 3.9°, respectively. The mean AOFAS score improved from a pre-operative of 44.6 points to 90.2 points in group I, and from 47.5 points to 87.7 points in group II. In group I, 26/29 patients (89.6 %) were happy with the cosmetic results of the surgery, compared to 20/31 patients (64.5 %) in group II. CONCLUSION: The results of this study support the idea that percutaneous distal metatarsal osteotomy yields good functional and radiological result and is associated with a high degree of postoperative patient satisfaction.

Resistant plantar fasciopathy: shock wave versus endoscopic plantar fascial release.

PURPOSE: To compare the results of Extracorporeal shock wave (ESWT) with a modified endoscopic plantar fasciotomy technique for the treatment of recalcitrant heel pain. METHOD: Sixty-five patients suffering from chronic heel pain that failed to respond to standard nonoperative methods were randomized to undergo either high-energy extracorporeal shock wave therapy (group 1), or modified endoscopic plantar fasciotomy (group 2). The primary outcome measure was the reduction of pain in the two groups from base line to month three post intervention at the first few steps in the morning. In addition, patients' functions were assessed using American Orthopedic Foot and Ankle-Hindfoot Scale (AOFAS) at week three, month three, and month 12 post-intervention, and finally, Roles and Maudsley scores were assessed. The primary analysis was intention-to-treat and involved all patients who were randomly assigned. RESULTS: Both groups achieved improvement from the base line at 3 weeks, 3 months and 12 months post-intervention. The success rate (Roles and Maudsley score excellent and good) in the ESWT group at month 12 was 70.6 %, while in the fasciotomy group, the success rate was 77.4 % (p = 0.19). CONCLUSION: In patients who had experienced failure of conventional treatment of plantar fasciopathy, both endoscopic plantar fasciotomy and shock wave therapy can be potentially helpful lines of management.

Resistant tennis elbow: shock-wave therapy versus percutaneous tenotomy.

Fifty-six patients who suffered from chronic persistent tennis elbow of more than six months duration were randomly assigned to two active treatment groups. Group 1 (n = 29) received high-energy extracorporeal shock wave treatment (ESWT; 1,500 shocks) at 18 kV (0.22 mJ/mm(2)) without local anaesthesia; group 2 (n = 27) underwent percutaneous tenotomy of the common extensor origin. Both groups achieved improvement from the base line at three weeks, six weeks, 12 weeks and 12 months post-intervention. The success rate (Roles and Maudsley score: excellent and good) at three months in the ESWT group was 65.5% and in the tenotomy group was 74.1%. ESWT appeared to be a useful noninvasive treatment method that reduced the necessity for surgical procedures.
