Sialendoscopy With Intraductal Steroid Irrigation in Patients With Sialadenitis Without Sialoliths

Sialendoscopy has emerged as a safe, effective and minimally invasive technique for management of obstructive and inflammatory salivary gland disease. The aim of our study was to analyze outcomes of sialendoscopy and steroid irrigation in patients with sialadenitis without sialoliths. We performed a retrospective analysis of patients who underwent interventional sialendoscopy with steroid irrigation from 2013 to 2016, for the treatment of sialadenitis without sialolithiasis. Twenty-two patients underwent interventional sialendoscopy with ductal dilation and steroid irrigation for the treatment of sialadenitis without any evidence of sialolithiasis. Conservative measures had failed in all. Eleven patients had symptoms arising from the parotid gland, 4 patients had symptoms arising from the submandibular gland, while 6 patients had symptoms in both parotid and submandibular glands. One patient complained of only xerostomia without glandular symptoms. The mean age of the study group which included 1 male and 21 females was 44.6 years (range: 3-86 years). Four patients had autoimmune disease, while 7 patients had a history of radioactive iodine therapy. No identifiable cause for sialadenitis was found in the remaining 11 patients. The mean follow-up period was 378.9 days (range: 16-1143 days). All patients underwent sialendoscopy with ductal dilation and steroid irrigation. Twelve patients showed a complete response and 9 patients had a partial response, while 1 patient reported no response. Only 3 patients required repeat sialendoscopy. The combination of sialendoscopy with ductal dilation and steroid irrigation is a safe and effective treatment option for patients with sialadenitis without sialoliths refractory to conservative measures. Prospective studies with a larger case series are needed to establish its role as a definitive treatment option.

Background: The Salto Talaris is a fixed-bearing implant first approved in the US in 2006. While early surgical outcomes have been promising, mid- to long-term survivorship data are limited. The aim of this study was to present the survivorship and causes of failure of the Salto Talaris implant, with functional and radiographic outcomes. Methods: Eighty-seven prospectively followed patients who underwent total ankle arthroplasty with the Salto Talaris between 2007 and 2015 at our institution were retrospectively identified. Of these, 82 patients (85 ankles) had a minimum follow-up of 5 (mean, 7.1; range, 5-12) years. The mean age was 63.5 (range, 42-82) years and the mean body mass index was 28.1 (range, 17.9-41.2) kg/m2. Survivorship was determined by incidence of revision, defined as removal/exchange of a metal component. Preoperative, immediate, and minimum 5-year postoperative AP and lateral weightbearing radiographs were reviewed; tibiotalar alignment (TTA) and the medial distal tibial angle (MDTA) were measured to assess coronal talar and tibial alignment, respectively. The sagittal tibial angle (STA) was measured; the talar inclination angle (TIA) was measured to evaluate for radiographic subsidence of the implant, defined as a change in TIA of 5 degrees or more from the immediately to the latest postoperative lateral radiograph. The locations of periprosthetic cysts were documented. Preoperative and minimum 5-year postoperative Foot and Ankle Outcome Score (FAOS) subscales were compared. Results: Survivorship was 97.6% with 2 revisions. One patient underwent tibial and talar component revision for varus malalignment of the ankle; another underwent talar component revision for aseptic loosening and subsidence. The rate of other reoperations was 21.2% ( n = 18), with the main reoperation being exostectomy with debridement for ankle impingement ( n = 12). At final follow-up, the average TTA improved 4.4 (± 3.8) degrees, the average MDTA improved 3.4 (± 2.6) degrees, and the average STA improved 5.3 (± 4.5) degrees. Periprosthetic cysts were observed in 18 patients, and there was no radiographic subsidence. All FAOS subscales demonstrated significant improvement at final follow-up. Conclusions: We found the Salto Talaris implant to be durable, consistent with previous studies of shorter follow-up lengths. We observed significant improvement in radiographic alignment as well as patient-reported clinical outcomes at a minimum 5-year follow-up. Level of Evidence: Level IV, retrospective case series.

Introduction: Managing distal femur non-union can be a struggle for any orthopedician as it brings along many perplexities which may not lead to satisfactory patient outcome. The target in these cases should be to reduce the morbidity and allow early rehabilitation of the patient and to accomplish this, megaprostheses can be a feasible option. The orthodox use of megaprostheses is in the musculo-skeletal oncologic surgeries but its use can be extended to traumatic etiologies. These can be offered as a single stage definite procedure in patients who have already undergone several previous surgeries. Here we report a series of four cases of persistent non-union of distal femur treated with megaprostheses and recommend this modality for achieving the desired goal but the indication should be meticulously selected. Hypotheses: Megaprosthesis as a definitive treatment option in persistent distal femur non-union and prevention of repeated surgical intervention. Methods: Four cases of persistent distal femur nonunion with failed osteosynthesis were selected who were initially treated with a distal femur locking plate. Results were assessed in terms of range of motion, limb length discrepancy, knee society score and osteointegration of the components. Results: The mean age of the patients at the time of DFEPR was 49 years (42-55). The mean follow up of patients was for approximately 2 years, with the longest follow up being 3.5 years for the first operated case of the series. The range of motion was from full extension to about 105 degrees of flexion with two patients having an extension lag of 10 degrees. Patients were ambulatory without support. Postoperatively, the mean knee society score was 83 (78–88) at last follow-up as compared to 29 (21-36) in the pre-operative period. No case of infection or loosening was reported. There was 1 cm of shortening in one patient in the operated limb which was compensated by giving shoe raise. Good osseointegration of the megaprosthesis was revealed on both anteroposterior and lateral radiographs. Conclusion: Although there are very limited studies on the use of megaprosthesis for traumatic cases, it can be considered as an alternative when we are left with only arthrodesis or amputation as the final option. Despite the operative challenges, there is marked improvement in pain and functional capacity as experienced by these severely limited patients, which are the hallmarks of a successful salvage. The use of distal femur mega-prosthesis is a novel acumen in cases, where bone stock at the fracture site at distal end of femur is so severely compromised that traditional revision osteosynthesis would not provide stable and durable fixation. The indications for this surgery must be rigorously selected and should only complement osteosynthesis procedures, which remain the reference treatment option.

Background: The number of ulnar collateral ligament (UCL) reconstructions in adolescent athletes has increased over the past 2 decades. Clinical results in this population have not been well studied. Purpose/Hypothesis: The purpose of this study was to evaluate the outcomes and return to sport after UCL reconstruction in a large group of adolescent baseball players. We hypothesized that excellent clinical outcomes and high rates of return to sport would be observed in this population at a minimum 2-year follow-up. Study Design: Case series; Level of evidence, 4. Methods: We reviewed 140 adolescent (aged ≤19 years) baseball players who underwent UCL reconstruction with the American Sports Medicine Institute (ASMI) technique by a single surgeon. Medical records were reviewed for patient demographics, injury characteristics, operative details, and surgical complications. Patient-reported outcomes were assessed using the Conway scale, the Andrews-Timmerman (A-T) score, the Kerlan-Jobe Orthopaedic Clinic (KJOC) score, and a 0- to 100-point subjective scale for elbow function and satisfaction. Return to sporting activity was assessed using a custom-designed questionnaire. Results: The mean age at the time of surgery was 18.0 years (range, 13-19 years), and the mean follow-up was 57.9 months (range, 32.4-115.4 months). Over half (60%) of patients were high school athletes. The mean duration of symptoms before surgery was 6.9 months (range, 0.5-60.0 months). Partial tears were identified in 57.9% of patients, and 41.3% of patients had preoperative ulnar nerve symptoms. Graft type included the ipsilateral palmaris in 77.1% of patients. Concomitant procedures were performed in 25% of patients. Outcomes on the Conway scale were “excellent” in 86.4% of patients. The mean A-T and KJOC scores were 97.3 ± 6.1 and 85.2 ± 14.6, respectively. Mean patient satisfaction was 94.4. Overall, 97.8% of patients reported returning to sport at a mean of 11.6 months (range, 5-24 months), and 89.9% of patients returned to sport at the same level of competition or higher. A total of 11.6% of patients went on to play professional baseball. Conclusion: UCL reconstruction with the ASMI technique is an effective surgical option in adolescents, with excellent outcome scores. At a minimum of 2-year follow-up, nearly 90% of patients returned to their preinjury level of sport.

The Mean

Background: Limited intermediate and no real long-term follow-up data have been published for total ankle arthroplasty (TAA) in the United States. This is a report of clinical follow-up data of a prospective, consecutive cohort of patients who underwent TAA by a single surgeon from 1999 to 2013 with the Scandinavian Total Ankle Replacement (STAR) prosthesis. Methods: Patients undergoing TAA at a single US institution were enrolled into a prospective study. These patients were followed at regular intervals with history, physical examination, and radiographs; American Orthopaedic Foot & Ankle Society (AOFAS) Ankle-Hindfoot Scale scores were obtained and recorded. Primary outcomes included implant survivability and functional outcomes scores. Secondary outcomes included perioperative complications such as periprosthetic or polyethylene fracture. Between 1999 and 2013, a total of 138 STAR TAAs were performed in 131 patients; 81 patients were female. The mean age at surgery was 61.5 ± 12.3 years (range, 30-88 years). The mean duration of follow-up for living patients who retained both initial components at final follow-up was 8.8±4.3 years (range 2-16.9 years). Results: The mean change in AOFAS Ankle-Hindfoot scores from preoperative to final follow-up was 36.0 ± 16.8 ( P < .0001). There were 21 (15.2%) implant failures that occurred at a mean 4.9 ± 4.5 years postoperation. Ten polyethylene components in 9 TAAs (6.5%) required replacement for fracture at an average 8.9 ± 3.3 years postoperatively. Fourteen patients died with their initial implants in place. Conclusion: This cohort of patients with true intermediate follow-up after TAA with the STAR prosthesis had acceptable implant survival, maintenance of improved patient-reported outcome scores, and low major complication rates. Level of Evidence: Level IV, case series.

The Mean

Background: Articular cartilage lacks the ability for intrinsic repair after acute injury, and focal articular cartilage lesions cause significant morbidity worldwide. Arthroscopic debridement (chondroplasty) represents the majority of cartilage procedures of the knee; however, limited data exist regarding outcomes after chondroplasty performed in isolation of concurrent procedures or not as a primary treatment for osteoarthritis (OA). Hypothesis: Arthroscopic mechanical chondroplasty is beneficial for patients with a focal cartilage lesion of the knee in the absence of meniscal pathology or OA. Study Design: Case series; Level of evidence, 4. Methods: Potential participants were identified by querying billing data from a 3-year period in a single-surgeon practice, and eligible patients were verified to meet inclusion criteria through electronic medical record review. OA was quantified through Kellgren-Lawrence (KL) scoring. Subjective patient-reported outcome (PRO) scores, including International Knee Documentation Committee (IKDC), Knee injury and Osteoarthritis Outcome Score (KOOS), Western Ontario and McMaster Universities Arthritis Index (WOMAC), Tegner, Lysholm, and Veterans RAND 12-Item Health Survey (VR-12), were collected preoperatively and at follow-up intervals. International Cartilage Repair Society (ICRS) grade and lesion size were determined at arthroscopy. Linear regression was used to determine the effect of baseline score on final follow-up score. Correlated regression equations were used to assess the relationship of covariates and change in PRO scores. Results: Fifty-three of 86 (62%) eligible participants completed postoperative questionnaires at an average of 31.5 months (range, 11.5-57 months). The mean patient age was 37.3 ± 9.7 years and mean body mass index (BMI) was 27.7 ± 5.6 kg/m2; 33 (62%) participants were women. The mean treated lesion size was 3.3 ± 1.9 cm2, of these, 36 (68%) were ICRS grade 2 or 3, and 42 (79%) patients had a KL score of 0 to −2. On average, the cohort demonstrated significant improvement from baseline for almost all PRO scores. Regression analysis of change in score versus baseline indicated participants with lower preoperative scores gained more benefit from chondroplasty. Correlated regression equations showed KL score >0 and male sex had a consistent positive effect on change in PRO scores, high ICRS grade had a consistent negative effect, and lesion size, age, and obesity had no effect. Eight patients (15%) required further surgical intervention within the follow-up period. Conclusion: The clinical efficacy of chondroplasty for repair of focal cartilage defects of the knee has not been studied in isolation from concurrent orthopaedic procedures. Our data show that arthroscopic mechanical chondroplasty is beneficial to patients, and response to surgical intervention is correlated with baseline PRO scores, sex, ICRS grade, and KL score.

Background: Fresh osteochondral allograft (OCA) transplantation represents a biologic restoration technique as an alternative treatment option for larger osteochondral lesions of the talus (OLT). The purpose of this study was to evaluate midterm outcomes after OCA transplantation for the treatment of OLT. Methods: Nineteen patients (20 ankles) received partial unipolar OCA transplant for symptomatic OLT between January 1998 and October 2014. The mean age was 34.7 years, and 53% were male. The average graft size was 3.8 cm2. All patients had a minimum follow-up of 2 years. Outcomes included the American Academy of Orthopaedic Surgeons Foot and Ankle Module (AAOS-FAM), the Olerud-Molander Ankle Score (OMAS), and pain and satisfaction questionnaires. Failure of OCA was defined as conversion to arthrodesis or revision OCA transplantation. Results: Five of 20 ankles (25%) required further surgery, of which 3 (5%) were considered OCA failures (2 arthrodesis and 1 OCA revision). The mean time to failure was 3.5 (range, 0.9 to 6.7) years. Survivorship was 88.7% at 5 years and 81.3% at 10 years. The median follow-up of the 17 patients with grafts in situ was 9.7 years. The mean OMAS improved significantly from 40 points preoperatively to 71 points postoperatively ( P < .05; range, 5 to 55). The mean postoperative AAOS-FAM core score was 81.5 ± 15 (range, 40.5 to 96.6). Fifteen of 17 patients responded to follow-up questions regarding their ankle; 14 patients reported less pain and better function, and 13 patients were satisfied with the results of the procedure. Conclusion: Our study of midterm results after OCA transplantations showed that this procedure was a reasonable treatment option for large OLT. Level of Evidence: Level IV, case series.

Introduction Pleuropulmonary blastoma (PPB) is an aggressive primary neoplasm of pleuropulmonary mesenchyme occurring in children. Given its rarity, the International Pleuropulmonary Blastoma Registry (IPPBR) was established in 1988 to collect and assess data on PPB worldwide. We assessed the clinical characteristics, histopathology, genetic studies, management, and treatment outcomes of patients with PPB in our institution, and compared with the published literature. Materials and Methods We retrospectively reviewed the medical records of all PPB cases diagnosed at Princess Margaret Hospital for Children in Western Australia over a period of 26 years (1990-2016). Results Seven children (4 boys and 3 girls) were treated for PPB at a mean age of 11.5 months (ranges 1 month to 3.55 years). Histopathology showed type I PPB in five, type II in one, and type III in one. All seven patients underwent thoracotomy/lobectomy of the corresponding site. One patient required additional bladder resection for coexisting rhabdomyosarcoma. One patient was found to be positive for DICER1 gene mutation. Six patients received adjuvant chemotherapy with vincristine, adriamycin, cyclophosphamide (VAC) regime, with the mean duration of treatment for five patients being 9.4 months excluding one patient who deceased without completion of chemotherapy. During a mean follow-up time of 9 years, the overall survival rate for this cohort was 85.7% (6/7). Conclusions Our results are similar to those reported in the literature. It is crucial for clinicians to consider PPB in the evaluation of patients presenting with a cystic lung abnormality, especially in cases with DICER1 mutation or a strong family history of unusual cancers.

There is a paucity of published data regarding the outcomes of this relatively new technique. We present the largest series in the literature, using three separate validated patient-reported outcome measures (EQ-5DL, VAS Pain and Manchester Oxford Foot Questionnaire (MOXFQ), for this time point. Methods: A single surgeon case series of patients with hallux valgus underwent primary third generation minimally invasive chevron and akin osteotomies (MICA) for hallux valgus correction. Between August 2015 and January 2019, 430 MICAs were performed in 295 patients that were eligible for 1 year follow up. Baseline and 1 year post-operative patient reported outcomes were collected for 242 feet in 194 patients (182 females; 12 males). Paired t-tests were used to determine the statistical significance of the difference between pre- and post-operative scores. Results: The mean age was 55.9 (range 16.3-84.9, standard deviation (s.d.) 12.5). At one year follow up, the mean MOXFQ scores had improved for each domain: Pain; baseline 41.9 (range 0-100, s.d. 21.8), reduced to 13.8 (range 0-90, s.d. 17.7, p<0.001); Walking; baseline 34.6 (range 0-100, s.d. 24.3) reduced to 9.8 (range 0-89.0, s.d. 18.0, p<0.001); Social interaction; baseline 45.4 (range 0-100, s.d. 22.8), reduced to 8.2 (range 0-75.0, s.d. 14.7, p<0.001). Mean VAS Pain score improved from 29.8 (range 0.0-90.0, s.d. 22.1) to 8.2 (range 0.00-64.0, s.d. 12.8, p<0.001). Mean EQ-5D index score improved from 0.755 (range 0.066-1.000, s.d. 0.136) to 0.891 (range 0.350-1.000, s.d. 0.124, p<0.001). Mean EQ-5D VAS score improved from 83.4 (range 28- 100, s.d. 12.4) to 85.6 (range 0-100, s.d. 14.2, p=0.047). Conclusion: This is the largest prospective case series of short-term patient reported outcomes using a validated assessment method for hallux valgus, following third generation MICA to date. These data show that this technique is effective at improving foot and ankle specific patient reported outcomes at 1 year. This cohort is being followed over the longer term.

Abstract BACKGROUND Advances in operative techniques and instrumentation technology have evolved to maximize patient outcomes following minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF). The transfacet MIS-TLIF is a modified approach to the standard MIS-TLIF that leverages a bony working corridor to access the disc space for discectomy and interbody device placement. OBJECTIVE To evaluate clinical and radiographic results following transfacet MIS-TLIF using an expandable interbody device. METHODS We performed a retrospective review of consecutive patients who underwent transfacet MIS-TLIF for degenerative lumbar spondylolisthesis. Patient-reported outcome measures for pain and disability were assessed. Sagittal lumbar segmental parameters and regional lumbopelvic parameters were assessed on upright lateral radiographs obtained preoperatively and during follow-up. RESULTS A total of 68 patients (61.8% male) underwent transfacet MIS-TLIF at 74 levels. The mean age was 63.4 yr and the mean follow-up 15.2 mo. Patients experienced significant short- and long-term postoperative improvements on the numeric rating scale for low back pain (–2.3/10) and Oswestry Disability Index (−12.0/50). Transfacet MIS-TLIF was associated with an immediate and sustained reduction of spondylolisthesis, and an increase in index-level disc height (+0.71 cm), foraminal height (+0.28 cm), and segmental lordosis (+6.83°). Patients with preoperative hypolordosis (<40°) experienced significant increases in segmental (+9.10°) and overall lumbar lordosis (+8.65°). Pelvic parameters were not significantly changed, regardless of preoperative alignment. Device subsidence was observed in 6/74 (8.1%) levels, and fusion in 50/53 (94.3%) levels after 12 mo. CONCLUSION Transfacet MIS-TLIF was associated with clinical improvements and restoration of radiographic sagittal segmental parameters. Regional alignment correction was observed among patients with hypolordosis at baseline.
