OBJECTIVE The aim of this study was to compare perioperative complications and postoperative outcomes between patients with lumbar recurrent stenosis without lumbar instability and radiculopathy who underwent decompression surgery and those who underwent decompression with fusion surgery. METHODS For this retrospective study, the authors identified 2606 consecutive patients who underwent posterior surgery for lumbar spinal canal stenosis at eight affiliated hospitals between April 2017 and June 2019. Among these patients, those with a history of prior decompression surgery and central canal restenosis with cauda equina syndrome were included in the study. Those patients with instability or radiculopathy were excluded. The patients were divided between the decompression group and decompression with fusion group. The demographic characteristics, numerical rating scale score for low-back pain, incidence rates of lower-extremity pain and lower-extremity numbness, Oswestry Disability Index score, 3-level EQ-5D score, and patient satisfaction rate were compared between the two groups using the Fisher’s exact probability test for nominal variables and the Student t-test for continuous variables, with p < 0.05 as the level of statistical significance. RESULTS Forty-six patients met the inclusion criteria (35 males and 11 females; 19 patients underwent decompression and 27 decompression and fusion; mean ± SD age 72.5 ± 8.8 years; mean ± SD follow-up 18.8 ± 6.0 months). Demographic data and perioperative complication rates were similar. The percentages of patients who achieved the minimal clinically important differences for patient-reported outcomes or satisfaction rate at 1 year were similar. CONCLUSIONS Among patients with central canal stenosis who underwent revision, the short-term outcomes of the patients who underwent decompression were comparable to those of the patients who underwent decompression and fusion. Decompression surgery may be effective for patients without instability or radiculopathy.

Category: Bunion, Midfoot/Forefoot Introduction/Purpose: Hallux valgus is a complex deformity of the great toe and is a major cause of pain for patients. Despite the variety of techniques, traditional osteotomies often do not address rotational deformities. A novel biplanar plating system was used to perform correction of metatarsal rotation at our institution starting in 2017. The purpose of this study was to determine the correction of rotational deformity and of radiographic parameters, maintenance of this correction (versus recurrence of hallux valgus), complication rates and patient-reported objective survey scores. We sought to determine prognostic factors for successful correction, including age, gender, and time of surgery. Methods: By retrospective chart review, we identified all patients treated by the novel biplanar plating at our institution. We recorded patient demographics, pre-operative range of motion and maltracking, surgical details, operative complications, and any subsequent surgery. Imaging was reviewed at pre-operative and post-operative visits to approximate the hallux valgus angle (HVA), intermetatarsal angle (IMA), and tibial sesamoid position (TSP). Outcome scores (AOFAS, FAAM, SF12 PCS and MCS) pre- operatively and post-operatively at 3 months, 6 months and 12 months were also recorded. The changes in these radiographic parameters and scores were then computed and analyzed to determine if there was an improvement with surgery. Results: Fifty-seven procedures (in 55 patients) were performed and evaluated. There were 8 complications and average follow- up time was 27.1 weeks (+13.8 weeks). Older age was significantly associated with more complications (p = 0.018). Gender and time of surgery did not show any significant association with complications. Radiographic parameters including HVA, IMA, and TSP were analyzed. At 3 and 6 months post-operatively, these parameters were significantly reduced from pre-operative values. At 12 months, there was a trend towards significant reduction (p values of 0.06, 0.06, and 0.053 respectively); however, there were fewer patients who maintained follow-up during this period. The Outcome scores showed improvement post-operatively, but only the AOFAS score showed statistical significance at 3 and 6 months. Conclusion: Although statistical analysis was limited due to our population size and the retrospective nature of the study, there was an overall improvement in both radiographic parameters and clinical outcome scores. Older patients are also at higher risk of complications. Malrotation correction with this biplanar plating system is a novel technique and does require meticulous training. With continued expansion of our patient database and further longitudinal analysis, we hope to determine not only if correction is maintained over time, but also if the steepness of the learning curve affects the number of complications earlier versus later in each individual surgeon’s experience.

Purpose: MCID scores for outcome measures are frequently used evidence-based guides to gage meaningful changes. To conduct a systematic review of the quality and content of the the minimal clinically important difference (MCID) relating to 16 patient-rated outcome measures (PROM) used in lower extremity. Methods: We conducted a systematic literature review on articles reporting MCID in lower extremity outcome measures and orthopedics from January 1, 1980, to May 10, 2016. We evaluated MCID of the 16 patient reported outcome measures (PROM) which were Harris Hip Score (HHS), Oxford Hip Score (OHS), Hip Outcome Score (HOS), Hip Disability and Osteoarthritis Outcome Score (HOOS), The International Knee Documentation Committee Subjective Knee Form (IKDC), The Lysholm Scale, The Western Ontario Meniscal Evaluation Tool (WOMET), The Anterior Cruciate Ligament Quality of Life Questionnaire (ACL-QOL), The Lower Extremity Functional Scale (LEFS), The Western Ontario and Mcmaster Universities Index (WOMAC), Knee İnjury And Osteoarthritis Outcome Score (KOOS), Oxford Knee Score (OKS), Kujala Anterior Knee Pain Scale, The Victorian Institute of Sports Assessment Patellar Tendinosis (Jumper’s Knee) (VİSA-P), Tegner Activity Rating Scale, Marx Activity Rating Scale, Foot And Ankle Outcome Score (FAOS), The Foot Function Index (FFI), Foot And Ankle Ability Measure (FAAM), The Foot And Ankle Disability Index Score and Sports Module, Achill Tendon Total Rupture Score(ATRS), The Victorian İnstitute Of Sports Assesment Achilles Questionnaire(VİSA-A), American Orthopaedic Foot and Ankle Society (AOFAS). A search of the PubMed/MEDLINE, PEDro and Cochrane Cen¬tral Register of Controlled Trials and Web of Science databases from the date of inception to May 1, 2016 was conducted. The terms “minimal clinically important difference,” “minimal clinically important change”, “minimal clinically important improvement” “were combined with one of the PROM as mentioned above. Results: A total of 223 abstracts were reviewed and 119 articles chosen for full text review. Thirty articles were included in the final evaluation. The MCID was mostly calculated for WOMAC and frequently reported in knee and hip osteoartritis, knee and hip atrhroplasties, femoraasetabular impingement syndrome and focal cartilage degeneration. In addition, Receiver Operating Characteristic (ROC) analysis was the most used method to report MCID. Conclusions: MCID is an important concept used to determine whether a medical intervention improves perceived outcomes in patients. Despite an abundance of methods reported in the literature, little work in MCID estimation has been done in the PRAM related to lower extremity. There is a need for future studies in this regard.

Thoracic myelopathy occurs less frequently than lumbar myelopathy. There are several causes of thoracic myelopathy of which ossification of the ligamentum flavum (OLF) is one. OLF has several unique features, arising posteriorly and causing proprioceptive issues first before extending to cause motor and sensory loss. We present a case of a 58-year-old gentleman with a six-month history of progressive lower limb weakness, numbness, back pain and recurrent falls due to OLF. Magnetic resonance and computed tomography imaging revealed extensive thoracic OLF and concomitant facet hypertrophy involving T6-7, T7-8, T9-10, T10-11 and L1-2. Severe central canal stenosis and L1-2 cauda equina root compression were also seen on radiological imaging. The patient developed sphincter disturbance during his admission and had difficulty passing urine. He underwent physiotherapy but was only able to sit and stand with the help of a walking frame at best. He did not regain motor or sensory function in his lower limbs although his back pain improved. Surgical decompression is associated with good neurological outcomes in OLF. Despite this, our patient declined surgery and opted for conservative therapy instead. We wish to highlight a rare case of thoracic myelopathy and the potentially irreversible neurological deterioration that occurs if there is no early surgical intervention.

The purpose of this study was to compare complication rates after total ankle replacement in 2 groups of patients based on polyethylene insert size. The total cohort was divided into 2 groups based on insert size. Group 1 included patients with polyethylene insert size less than 10 mm in thickness. Group 2 included patients with polyethylene insert sizes 10 mm and larger. Available charts were reviewed for patients who underwent primary total ankle arthroplasty by one surgeon. Patient demographics, polyethylene insert size, implant used, concomitant procedures, postoperative complications, and patient-reported outcome scores were recorded. One hundred patients were available for follow-up and were included in this study, which ranged from March 2012 to July 2017. The average follow-up was 31.3 months (range = 10-60 months). Forty-eight females and 52 males were included in this study. There were a total of 63 patients in group 1 and 47 patients in group 2. The total complication rate for patients in group 1 was 11.1% (7/63), and in group 2 it was 16.2% (6/32). There was no statistical significance in complication rates when comparing the 2 groups (P = 0.5427). All patients underwent at least one concomitant procedure at the time of initial ankle replacement. Our findings show that total ankle replacement complication rates are equal when comparing large polyethylene inserts commonly utilized to correct deformities, versus small polyethylene inserts commonly utilized in primary resurfacing.

Study Design: Retrospective study. Objective: To describe the MRI findings of RNRs in patients with low back pain, and observe the imaging findings and the clinical outcome post decompression surgery. Methods: The lumbar spine MRI of 202 patients (122 females) with proven RNRs were retrospectively reviewed. The morphology and the location of the RNRs in relation to the level of stenosis were described. The level(s), grade and cause of lumbar canal stenosis were recorded. The persistence of symptoms and the imaging findings on follow up post decompression surgery were recorded. The imaging findings were correlated among each other and with patients’ demographics. Results: Two distinctive morphological appearance of the RNRs were noted: loop (56.4%), and serpentine-shaped. In the majority of the cases the RNRs were located above the level of stenosis (79.7%). Eighteen patients underwent decompression surgery, only 4 patients remained symptomatic post decompression surgery. The RNRs changed in shape and location after decompression surgery. Age was a strong predictor value in the location of the RNRs. There was no correlation between the shape and location of the RNRs, or with the gender of the patients. Conclusion: RNRs is not an uncommon finding on lumbar spine MRI with lumbar canal stenosis. Its importance remains a controversy. A common language between the radiologists and the clinicians is mandatory to aid in the management planning.

Background: Cases of thoracic stenosis with cauda equina syndrome are rare. The thoracal canal is relatively narrow compared with cervical and lumbar, so the less pressure on the lower thoracal region is the thoracic vertebral height 11 which is the initial release of the cauda equine nerve root can cause complaints of cauda equina syndrome.Case: A 50-year-old male presented pain in both legs for 3 years, accompanied by weakness in the legs, numbness in the buttocks, and erectile dysfunction. Thoracal MRI examination shows severe spinal stenosis at 11th-12th thoracal vertebra with ligamentum flavum hypertrophy. Second patient, a 70-year-old man complained of weak legs since 1 week, accompanied by low back pain, numbness in the buttocks, and difficulty defecating. Thoracal MRI examination shows severe spinal stenosis in the 10th-11th thoracal vertebra. Both patients immediately underwent selective decompression surgery, laminotomy, and flavectomy at thoracal level showed satisfactory results based on improvement in clinical symptoms.Discussion: Leg weakness, hypoesthesia in the buttocks and pubic area, erectile dysfunction is the cauda equina syndrome. The exit of the first cauda equine nerve can be placed at 11th thoracic vertebra, so the presence of stenosis at that level and bellow can cause symptoms of the cauda equina syndrome. MRI examination is needed to ensure that there is severe spinal stenosis at the level of the thoracal-lumbar spine, according to the level of neurological disorders. The surgery of decompression is immediately carried out in the case of cauda equina syndrome because it is an emergency state.Conclusion. In cases with complaints of the cauda equina syndrome, thoracic stenosis can be the cause due to stenosis of the lower thoracic region which is the initial root of the cauda equina nerve. Confirm accurate diagnosis is with MRI.

Background: Lumbosacral plexus entrapment syndrome (LPES) is a little-known but common cause of chronic lumbopelvic and lower extremity pain. The authors document the clinical course of 61 patients who were diagnosed and treated for LPES between May 2016 and October 2018. The study is aimed to evaluate the efficacy of our proposed diagnostic and conservative treatment protocol for LPES, clinically.Methodology: This is a retrospective cohort study of patients suffering from LPES. Patients were included in this study if they compatible symptoms with LPES with symptoms of low back, pelvic, groin, genital, thigh or calf pain after other more common etiologies have been excluded. Additionally, these patients had at least 5 positive provocative Tinel’s tests applied to various lumbopelvic and lower extremity (LPLE) nerve branches yielding => 7 (numeric rating scale) NRS, and weakness of one or more myotomes of the lower body. The group in its entirety was treated with gentle strengthening of the psoas major and piriformis muscles. The primary outcome measure was patient reported satisfaction and improvement including: Full, significant, moderate, slight, or no improvement in pain and symptoms. Patients were followed for up to two years.Results: The most common complaints amongst the patient pool were low back, groin, pelvic, posterior/lateral calf pain. Additionally, 17 patients (28%) stated that everything in the LPLE hurts, consistent with plexalgia. 13 patients were lost to follow-up as they did not reschedule treatment, for unknown reasons. Amongst the remaining 48 patients, 25 recovered fully (52%), 12 significantly (25%), and five moderately (10,4%). Five patients had a slight improvement (10,4%), and two no improvement whatsoever (4%). The average recovery times were mostly consistent with the time of affliction. Patients with a symptom duration of less than one year, generally recovered within 4 months. One to four years, within 10,5 months. Five to nine years, 7,5 months. And, finally, more than 10 years, within 18 months.Conclusion: Non-specific pain syndromes in the LPLE where other causes have been excluded, may be attributable to underlying LPES. In this study, a high correlation between the diagnostic & interventional protocols, and beneficial patient outcomes were demonstrated. However, more statistical and long-term research is needed.Citation: Larsen K, Chien GCC. Lumbosacral plexus entrapment syndrome. Part Two: Symptomology and rehabilitative trials.

Background: Smartphones comprise a promising tool for symptom monitoring in patients with unipolar depressive disorder (UD) collected as either patient-reportings or possibly as automatically generated smartphone data. However, only limited research has been conducted in clinical populations. We investigated the association between smartphone-collected monitoring data and validated psychiatric ratings and questionnaires in a well-characterized clinical sample of patients diagnosed with UD.Methods: Smartphone data, clinical ratings, and questionnaires from patients with UD were collected 6 months following discharge from psychiatric hospitalization as part of a randomized controlled study. Smartphone data were collected daily, and clinical ratings (i.e., Hamilton Depression Rating Scale 17-item) were conducted three times during the study. We investigated associations between (1) smartphone-based patient-reported mood and activity and clinical ratings and questionnaires; (2) automatically generated smartphone data resembling physical activity, social activity, and phone usage and clinical ratings; and (3) automatically generated smartphone data and same-day smartphone-based patient-reported mood and activity.Results: A total of 74 patients provided 11,368 days of smartphone data, 196 ratings, and 147 questionnaires. We found that: (1) patient-reported mood and activity were associated with clinical ratings and questionnaires (p &lt; 0.001), so that higher symptom scores were associated with lower patient-reported mood and activity, (2) Out of 30 investigated associations on automatically generated data and clinical ratings of depression, only four showed statistical significance. Further, lower psychosocial functioning was associated with fewer daily steps (p = 0.036) and increased number of incoming (p = 0.032), outgoing (p = 0.015) and missed calls (p = 0.007), and longer phone calls (p = 0.012); (3) Out of 20 investigated associations between automatically generated data and daily patient-reported mood and activity, 12 showed statistical significance. For example, lower patient-reported activity was associated with fewer daily steps, shorter distance traveled, increased incoming and missed calls, and increased screen-time.Conclusion: Smartphone-based self-monitoring is feasible and associated with clinical ratings in UD. Some automatically generated data on behavior may reflect clinical features and psychosocial functioning, but these should be more clearly identified in future studies, potentially combining patient-reported and smartphone-generated data.

Proximal Hamstring

Background: Partial avulsions of the proximal hamstring origin remain a challenging problem with nonoperative treatments frequently providing limited success. The literature is limited regarding the outcomes of operative management in the active and athletic population. Hypothesis: Surgical fixation of proximal hamstring ruptures will have favorable outcomes at midterm follow-up. Study design: Case series; Level of evidence, 4. Methods: A total of 64 patients with partial avulsions of the proximal hamstring origin treated with surgical fixation by a single surgeon were reviewed at a 2-year minimum follow-up. All patients had initially undergone failed nonoperative treatment. Patient-reported outcome scores on the Lower Extremity Functional Score (LEFS), Marx Activity Rating Scale, custom LEFS and Marx scales, and total proximal hamstring score were evaluated. Data on patient-perceived strength, return to sport, and satisfaction were also collected. Results: The cohort included 27 male and 37 female (N = 64) patients with a mean age of 47.3 years (range, 16-65 years), and all were reviewed at a mean 6.5-year (range, 2-12.5 years) follow-up. The average postoperative LEFS was 96% (range, 68%-100%), with the custom LEFS being 90% (range, 39%-100%). The mean Marx score was 12.4 (range, 4-16). The Marx custom score demonstrated no disability with activities of daily living. The mean total proximal hamstring score was 94% (range, 69%-100%). No differences in any outcome measures were seen when comparing acute versus chronic repairs. Three patients underwent further hamstring surgery. No patients reported symptoms of numbness in the operative extremity at rest, while 3 patients had a superficial stitch abscess treated with antibiotics alone. The most commonly reported difficulty was with prolonged sitting. Ninety-seven percent were satisfied with surgery, 92% reported they could participate in strenuous activity, and 97% estimated their strength to be >75%, while 64% estimated it to be 100% of their contralateral side. Patients returned to sport at an average of 11.1 months, and all that returned were satisfied with their performance. Conclusion: Both early and delayed anatomic surgical repair of partial proximal hamstring avulsions leads to successful functional outcomes, a high rate of return to athletic activity, and low complication rates at the 6.5-year follow-up. Nonoperative treatments should first be attempted.
