Introduction: Circumferential fusion by the anterior (ALIF) or transforaminal (TLIF) approach combined with posterior instrumentation is currently used for the surgical treatment of low-grade isthmic spondylolisthesis. But few studies have compared the clinical and radiological outcomes of various interbody fusion techniques. The objective of this study was to compare the clinical and radiological results at 2 years postoperative of two fusion techniques-TLIF versus ALIF plus posterior instrumentation-for low-grade isthmic spondylolisthesis in adults., Materials and Methods: This was an observational multicenter study done at nine French healthcare facilities specialized in spine surgery. The inclusion criteria were minimum age of 18 years, grade 1-3 isthmic spondylolisthesis, ALIF+posterior fixation (ALIF+PS) or TLIF, minimum follow-up of 2 years. Clinical and radiological evaluations were done preoperatively and at 2 years of follow-up. A lumbar CT scan was done at 1 year postoperative to evaluate fusion., Results: The cohort consisted of 89 patients (50 women, 39 men) with a mean age of 47.7±12.3 (18-79) years. The patients in the ALIF groups (n=71) had a significantly longer hospital stay than those in the TLIF group (n=18): 5.7 days versus 4.6 days (p=.04). However, their medical leave from work was significantly shorter: 31.0 weeks versus 40.7 (p=.003). Lumbar pain VAS diminished faster in the ALIF groups, with a significantly larger drop than the TLIF group in the first 3 months postoperative. Only the increase in lumbar disc lordosis was larger in the ALIF group: 11.7°±12.0° versus 6.0°±11.7° (p=.036). There was a significant correlation between the increase in global lordosis and reduction in lumbar VAS at 2 years postoperative (ρ=-0.3295; p=.021)., Conclusion: ALIF+PS provides a faster relief of postoperative low back pain than TLIF but there are no significant clinical differences between techniques at 2 years of follow-up. Despite better restoration of disc lordosis in the ALIF+PS group, there was no difference in the restoration of global lordosis., Level of Evidence: III; multicenter comparative study., (Copyright © 2023 Elsevier Masson SAS.

Background: Metatarsal osteotomy is a major means of treating mechanical metatarsalgia. Open techniques are widely used, and notably that described by Weil. They have, however, certain drawbacks, and new types of osteotomy have been developed. Percutaneous techniques are presently very much in favor, and Distal Metatarsal Minimally Invasive Osteotomy (DMMO) has emerged as a treatment for metatarsalgia. Although very widely used, it is poorly codified in the literature., Method: The present study detailed DMMO techniques and their variants (oblique and reverse), with corresponding indications and treatment decision-tree., Results: Initial findings seem encouraging, with functional results comparable to those of open surgery. Postoperative edema and radiologic bone healing time seem to be longer in DMMO. There is, on the other hand, no difference regarding stiffness., Conclusion: DMMO is an effective option to treat metatarsalgia, with variants enabling adaptation to foot morphology, but needing confirmation by studies with higher levels of evidence., (Copyright © 2021 Elsevier Ltd.

Exertional compartment syndrome of the forearm is a rare pathology, occurring almost exclusively in motorcycle racers. The results of endoscopic techniques are similar to those of open fasciotomies, but they are less invasive and leave smaller scars. The aim of our study was to present a new endoscopic technique for superficial fasciotomy using the Agee® system and to describe the results. This was a single-center, retrospective descriptive study of 21 patients (36 forearms) operated on between 2006 and 2016. All patients but one were competitive motorcycle racers. The mean operating time was 38.2min (standard deviation (SD), 10.5min). The QuickDASH score was 23.3±10.2% preoperatively versus 1±2% postoperatively (mean±SD). Among the 18 patients who came back for a follow-up visit after 4.9±2.7 years, 17 (94%) were satisfied or very satisfied. The mean time before returning to sport was 4.3 weeks (SD, 1.8 weeks), 9 patients (50%) at the same level as before surgery, 8 (44%) at a higher level, and one at a lower level. There were a few minor complications (superficial vascular lesions, hematoma, transitory hypoesthesia) and symptoms recurred in two patients. Our technique yields outcomes similar to those of other published endoscopic procedures and allows early return to sport. It has the advantage of being based on the Agee endoscope, which is commonly used to treat carpal tunnel syndrome, making the procedure easy to master., (Copyright © 2020.

Background: A careful analysis of the reasons for ACL reconstruction failure is essential to selection of the optimal surgical revision technique designed to ensure good rotational stability and to minimise the risk of re-rupture., Objective: To evaluate anterolateral ligament (ALL) stabilisation during revision ACL reconstruction., Hypothesis: ALL stabilisation during revision ACL reconstruction provides good rotational stability without increasing the risk of complications., Material and Methods: This multicentre study included 349 patients, 151 retrospectively and 198 prospectively. There were 283 males and 66 females. Inclusion criteria were an indication for revision ACL reconstruction surgery with combined intra-articular reconstruction and ALL stabilisation after failed autograft ACL reconstruction, and intact PCL. Exclusion criteria were primary ACL reconstruction and concomitant peripheral medial and/or lateral lesions. Each patient underwent a clinical and radiographic evaluation before and after revision surgery. Before revision surgery, the mean IKDC score was 56.5±15.5 and 96% of patients were IKDC C or D., Results: Rates were 5.0% for early and 10.5% for late postoperative complications. Lachmann's test had a hard stop at last follow-up in 97% of patients. The pivot-shift test was positive in 1% of patients. The mean subjective IKDC score was 84.5±13.0 and 86.5% of patients were IKDC A or B. The proportions of patients with radiographic knee osteoarthritis at last follow-up was unchanged for the lateral tibio-femoral and patello-femoral compartments but increased by 9.7% to 21.2% for the medial tibio-femoral compartment. The re-rupture rate was 1.2% and the further surgical revision rate was 5.4%., Conclusion: Anterior laxity at last follow-up was consistent with previous studies of revision ACL reconstruction. However, rotational stability and the re-rupture risk were improved. ALL stabilisation is among the techniques that deserve consideration as part of the therapeutic options for revision ACL reconstruction., Level of Evidence: IV, retrospective and prospective cohort study., (Copyright © 2017 Elsevier Masson SAS.

Introduction: During anterior cruciate ligament (ACL) reconstruction procedures, anterolateral reconstruction (ALR) can also be performed to improve the knee's rotational stability. However, the effectiveness of this supplemental technique and its impact on the risk of retears and on the onset of secondary degenerative changesare controversial., Hypothesis: ALR improves control over the pivot shift, reduces the retear risk and delays the appearance of secondary degenerative lesions., Material and Methods: Clinical examination, knee laxity measurements and X-ray evaluations were done in 478 patients with more than 3years' follow-up after combined ACL and ALR from 11 participating hospitals. The mean patient age at the time of surgery was 28years. Eighty-eight percent of the patients participated in pivot sports and 45% were competitive athletes. The findings of this study were compared to historical isolated ACL reconstruction data., Results: The average follow-up was 6.8years. No detectable pivot shift was found in 83% of patients, while 12.8% of patient had a smooth glide. The side-to-side difference in anteroposterior knee laxity with maximum manual force was less than 3mm in 66% of patients and less than 5mm in 95%. The retear rate was 5.4%, with half of these patients undergoing revision ACL surgery. Secondary meniscus damage requiring surgery occurred in 6.3% of patients; the radiological osteoarthritis rate was 17.5%., Discussion: When compared to historical ACL reconstruction data, combined intra- and extra-articular reconstruction does not increase the complication rate. At a mean follow-up of 6.8years, it provides better control over the pivot shift along with a low retear rate and low occurrence of secondary meniscus injuries., Level of Evidence: IV, multicenter study., (Copyright © 2017 Elsevier Masson SAS.

Introduction: Lateral tenodesis (LT) is performed to limit the risk of iterative tear following anterior cruciate ligament (ACL) reconstruction in at-risk patients. By adding an extra procedure to isolated ACL graft, LT reconstruction increases operating time and may complicate postoperative course. The objective of the present study was to evaluate the rate of early complications. The study hypothesis was that associating ALL reconstruction to ACL reconstruction does not increase the complications rate found with isolated ACL reconstruction., Material and Methods: A prospective multicenter study included 392 patients: 70% male; mean age, 29.9 years; treated by associated ACL and LT reconstruction. All adverse events were inventoried., Results: Mean hospital stay was 2 days, with 46% day-surgery. Walking was resumed at a mean 27 days, with an advantage for patients treated by the hamstring technique. The early postoperative complications rate was 12%, with 1.7% specifically implicating LT reconstruction: pain, hematoma, stiffness in flexion and extension, and infection. There was a 5% rate of surgical revision during the first year, predominantly comprising arthrolysis for extension deficit. The 1-year recurrence rate was 2.8%., Discussion: The complications rate for combined intra- and extra-articular reconstruction was no higher than for isolated intra-articular ACL reconstruction, with no increase in infection or stiffness rates. The rate of complications specific to ALL reconstruction was low, at 1.7%, and mainly involved fixation error causing lateral soft-tissue impingement., Level of Evidence: IV, prospective multicenter study., (Copyright © 2017.
