Background: Forefoot adduction is the most common residual deformity in the treatment of pediatric clubfoot. Little documentation exists regarding its late occurrence and early detection. A retrospective analysis was conducted to determine the effect of primary posterior medial release for idiopathic clubfoot that had failed to improve with conservative treatment or had presented after a treatment delay and a subsequent forefoot adduction correction with a cuboid-cuneiform osteotomy. Methods: Radiographic evaluations were conducted of all of the surgical procedures performed at our institution for idiopathic clubfoot during a specified period. Preoperative and postoperative talo–first metatarsal and talocalcaneal angles were measured radiographically. Of 138 patients with clubfoot deformity who met the inclusion criteria, 51 underwent a primary posterior medial release; of these patients, 18 (26 feet) underwent a subsequent cuboid-cuneiform osteotomy. Results: The average preoperative and postoperative talo–first metatarsal anteroposterior angles for patients who underwent primary posterior medial release were 44.6° and 26.8°, respectively. The mean reduction in forefoot adduction was 17.8° (P < .05). After the osteotomy, the average talo–first metatarsal anteroposterior angle was 16°, with an average reduction of 10.8° (P < .05). Mean follow-up was 61.2 months. The average patient age was 3.2 years. Conclusions: Eighteen (35%) of 51 patients who underwent a posterior medial release required a subsequent cuboid-cuneiform osteotomy. The average reduction of 10.8° was statistically significant and has also proved to be clinically significant in the overall correction of the deformity.

Objectives: Acetabular labral tears distort the architecture of the hip and result in accelerated osteoarthritis and increases in femoroacetabular stress. Uncomplicated tears with preserved, native fibers can be fixed to acetabular bone using labral repair techniques, which have shown improved outcomes when compared to the previous gold standard, labral debridement and resection. If the tear is complex or the labrum is hypoplastic, labral reconstruction techniques can be utilized to add grafted tissue to existing, structurally intact tissue or completely replace a deficient labrum. The ultimate goal is to reconstruct the labrum to restore the labral seal and hip biomechanics. Clinical outcomes using autografts and allografts from multiple sources for segmental and whole labral reconstruction have been reported as successful. However, reconstruction using autografts has been associated with substantial donor-site morbidity. More recently, all-arthroscopic capsular autograft labral reconstruction has been proposed as a way to repair complex or irreparable tears without the downside of donor-site morbidity. Since all-arthroscopic capsular autograft labral reconstruction is a novel technique, there is limited data in the literature on patient outcomes. The purpose of this study is to report outcomes in patients who have undergone this procedure at a minimum 2-year follow-up. Methods: This is a retrospective case series of prospectively collected data on patients who underwent arthroscopic acetabular labral repair by a senior surgeon between December 2013 and May 2017. Patients who failed at least 3 months of conservative therapy and had a symptomatic labral tear on magnetic resonance angiography (MRA) were designated for hip arthroscopy. The inclusion criteria for this study were adult patients age 18 or older who underwent arthroscopic labral repair with capsular autograft labral reconstruction and completion of a minimum 2-year follow-up. Intraoperatively, these patients were found to have a labrum with hypoplastic tissue (width < 5 mm), complex tearing, or frank degeneration of native tissue. Patients with lateral center edge angle (LCEA) ≤ 20° were excluded from analysis. Using the patients’ clinical visit notes with detailed history and physical exam findings, demographic and descriptive data were collected, including age, sex, laterality, body mass index (BMI), and Tönnis grade to evaluate osteoarthritis. Patients completed patient-reported outcome measures and postoperatively at 3 months, 6 months, 12 months, and annually thereafter. Results: A total of 72 hips (69 patients) met inclusion criteria. No patients were excluded. The cohort consisted of 37 (51.4%) male and 35 (48.6%) female patients. The minimum follow-up was 24 months, with an average follow-up of 30.3 ± 13.2 months (range, 24-60). The mean patient age was 44.0 ± 10.4 years (range 21-64), with mean body mass index of 26.3 ± 4.3. The cohort consisted of 6 (8.3%) Tönnis grade 0, 48 (66.7%) Tönnis grade 1, and 18 (25.0%) Tönnis grade 2. Two (2.8%) progressed to total hip arthroplasty. Intraoperatively, 5 (6.9%) patients were classified as Outerbridge I, 14 (19.4%) Outerbridge II, 45 (62.5%) Outerbridge III, and 8 (11.1%) Outerbridge IV. Seventy-two (100.0%) patients had a confirmed labral tear, 34 (47.2%) isolated pincer lesion, 4 (5.6%) isolated CAM lesion, and 27 (37.5%) had both a pincer and CAM lesion. The mean of differences between preoperative and 24-month postoperative follow-up PROMs was 22.5 for mHHS, 17.4 for HOS-ADL, 32.7 for HOS-Sport, 22.9 for NAHS, 33.9 for iHOT-33. (Figure 1) The mean of differences between preoperative and final post-operative follow-up PROMs was 22.1 for mHHS, 17.6 for HOS-ADL, 33.2 for HOS-Sport, 23.3 for NAHS, and 34.2 for iHOT-33. (Table 1) Patient age and presence of femoroacetabular impingement were independently predictive of higher postoperative PROM improvements at final follow-up, whereas Tönnis grade was not. (Table 2) The proportion of patients to achieve the minimally clinically important difference (MCID), substantial clinical benefit (SCB), and patient acceptable symptom state (PASS) thresholds were also calculated. (Table 3) Conclusions: In this study of 72 hips undergoing arthroscopic labral repair with capsular autograft labral reconstruction, we found excellent outcomes that exceeded the MCID thresholds in the majority of patients at an average 30.3 months follow-up. When compared to capsular reconstruction from autografts and allografts, this technique offers the potential advantages of minimized donor-site morbidity and fewer complications, respectively.

INTRODUCTION Adduction of the forefoot is the most common residual deformity in idiopathic clubfoot. The ‘bean-shaped foot’, which is a term used to describe a clinical deformity of forefoot adduction and midfoot supination, is not uncommonly seen in resistant clubfoot. SUBJECTS AND METHODS Fifteen children (20 feet) with residual forefoot adduction in idiopathic clubfeet aged 3–7 years were analyzed clinically and radiographically. All of the cases were treated by double column osteotomy (closing wedge cuboid osteotomy and opening wedge medial cuneiform osteotomy) with soft tissue releases (plantar fasciotomy and abductor hallucis release), to correct adduction, supination and cavus deformities. Pre-operative measurements of certain foot angles were compared with their corresponding postoperative values. RESULTS A grading system for evaluation of the results using a point scoring system was suggested to evaluate accurately both clinical and radiographic results after a follow-up period of an average of 2.3 years. Eight feet (40%) had excellent, eight (40%) good, three (15%) fair, and one (5%) poor outcome. There was no major complication. There was significant improvement in the result (P > 0.04). CONCLUSIONS Double column osteotomy can be considered superior to other types of bone surgeries in correction of residual adduction, cavus and rotational deformities in idiopathic clubfoot.

The objective of our study was to examine the changes in coagulation parameters and inflammatory reaction over the course of 15 days in patients with severe sepsis. We tried to identify mechanisms by which sepsis-induced pathophysiological changes may influence the effectiveness of subcutaneously (SC) administered enoxaparin 40 mg once daily. A total of 16 patients (8 men, 8 women; age 35-83 years) meeting the inclusion criteria of severe sepsis were enrolled in this study. The follow-up was performed on days 1, 2, 3, 6, 9, 12, and 15 of hospitalization at the intensive care unit (ICU). Blood coagulation (activated partial thromboplastin time [aPTT], prothrombin time [PT], fibrinogen, antithrombin (AT), protein C [PC], D-dimer, fragment 1.2 [F1.2], factor Xa [FXa] inhibition) and inflammatory reactants (interleukin 6 [IL-6], C-reactive protein [CRP], orosomucoid, α-1-antitrypsin) were tested. The mean FXa inhibition was 0.17 (±0.17) IU/mL. The arbitrarily established range of FXa inhibition for prophylaxis, 0.2 to 0.4 IU/mL, was reached in 22 cases (20%), while in 74 cases (68%), it was below and in 13 cases (12%) above the aforementioned range. Factor Xa inhibition positively correlated with AT (r = .42; P < .001) and PC (r = .45; P < .001) activities. A negative correlation was found between the FXa inhibition and α-1-antitrypsin concentrations (r = —.33; P = .01) but only in the subgroup with α-1-antitrypsin concentrations ≥2.2 g/L. We confirmed that in most patients with sepsis, the prophylaxis with enoxaparin did not lead to the required FXa inhibition. The inhibition of FXa by enoxaparin depends mainly on the AT and PC activities.

INTRODUCTION Some studies have considered abdominal aortas of 2.6–2.9 cm diameter (ectatic aortas) at age 65 years as being abnormal and have recommended surveillance, whereas others have considered these normal and surveillance unnecessary. It is, therefore, not clear how to manage patients with an initial aortic diameter between 2.6–2.9 cm detected at screening. The aim of this study was to evaluate growth rates of ectatic aortas detected on initial ultrasound screening to determine if any developed into clinically significant abdominal aortic aneurysms (AAAs; > 5.0 cm) and clarify the appropriate surveillance intervals for these patients. PATIENTS AND METHODS Data were obtained from a prospective AAA screening programme which commenced in 1992. The group of patients with initial aortic diameters of 2.6–2.9 cm with a minimum of 1-year follow-up were included in this study (Group 2). This was further divided into two subgroups (Groups 3a and 3b) based on a minimum follow-up interval obtained from outcome analysis. Mean growth rate was calculated as change in aortic diameter with time. The comparison of growth rates in Groups 3a and 3b was performed using the t-test. The number and proportion of AAAs that expanded to ≥ 3.0 cm and ≥ 5.0 cm in diameter were also calculated. RESULTS Out of 999 patients with AAA ≥ 2.6 cm with minimum 1-year follow-up, 358 (36%) were classified as ectatic aortas (2.6–2.9 cm) at initial ultrasound screening with the mean growth rate of 1.69 mm/year (95% CI, 1.56–1.82 mm/year) with a mean follow-up of 5.4 years. Of these 358 ectatic aortas, 314 (88%) expanded into ≥ 3.0 cm, 45 (13%) expanded to ≥ 5.0 cm and only 8 (2%) expanded to ≥ 5.5 cm over a mean follow-up of 5.4 years (range, 1–14 years). No ectatic aortas expanded to ≥ 5.0 cm within the first 4 years of surveillance. Therefore, the minimum follow-up interval was set at 4 years and this threshold was then used for further analysis. The mean growth rate in Group 3a (< 5.0 cm at last scan) was 1.33 mm/year (95% CI, 1.23–1.44 mm/year) with a mean follow-up of 7 years compared to Group 3b (≥ 5.0 cm at last scan) with the mean growth rate of 3.33 mm/year (95% CI 3.05–3.61 mm/year) and a mean follow-up of 8 years. The comparison of mean growth rates between Groups 3a and 3b is statistically significant (t-test; T = 13.00; P < 0.001). CONCLUSIONS One-third of patients undergoing AAA screening will have ectatic aortas (2.6–2.9 cm) and at least 13% of these will expand to a size of ≥ 5.0 cm over a follow-up of 4–14 years. A threshold diameter of 2.6 cm for defining AAAs in a screening programme is recommended and ectatic aortas detected at age 65 years can be re-screened at 4 years after the initial scan. A statistically significant difference was found in the growth rates of ectatic aortas with minimum 4 years follow-up, expanding to ≥ 5.0 cm compared to those less than 5.0 cm at last surveillance scan. Further studies are required to test the hypothesis of whether growth rate over the first 4 years of surveillance will identify those who are most likely to expand to a clinically significant size (> 5.0 cm).

Category: Bunion Introduction/Purpose: Hallux valgus is a common deformity of the forefoot. There are over 130 procedures described to correct hallux valgus. Classically, the treatment of mild to moderate hallux valgus is with a distal metatarsal osteotomy. A variety of fixation techniques have been described for use with this osteotomy most of which require partial or non-weight bearing until the osteotomy is healed. Tension Band fixation is a well-known principle in orthopedic surgery. The goal of the present study is to radiographically assess the maintenance of distal first metatarsal osteotomy fixation using a novel tension band device (Re+Line tension band bunion plate system, Nextremity Solutions) with immediate post-operative weight-bearing. Methods: The patient database for one surgeon was retrospectively reviewed for patients that underwent hallux valgus correction with the Re+Line tension band device between 2014 and 2017. Postoperative protocol included a soft dressing, firm surgical shoe, and weight-bearing as tolerated with a cane. Patients were excluded if fixation was achieved with something other than a tension band construct. Radiographs were obtained and reviewed retrospectively by 3 authors. Pre and postoperative hallux valgus (HVA) and intermetatarsal angles (IMA) were measured as described previously in the literature, and the changes in correction compared. Maintenance of correction and hardware integrity were assessed at final follow-up after weight bearing as tolerated in a surgical shoe in the postoperative period. Statistical analysis was performed using a Wilcoxon signed-rank test for the changes in HVA and IMA. Results: There was a total of 72 patients and 76 toes that underwent hallux valgus correction with a tension band construct, at a mean follow-up of 4.36 months. 68 of 72 patients were female. The average age was 60.8 years old. The mean preoperative HVA was 27.1 degrees. The mean postoperative HVA was 6.14 degrees, with a mean correction of 20.22 degrees (p<0.001). The mean preoperative IMA was 14.14 degrees. The mean postoperative IMA was 6.10 degrees, with a mean correction of 7.98 degrees (p<0.001). There was loss of reduction found in 6 of 76 toes (7.89%).There were zero cases of hardware failure. All osteotomies healed at final follow-up. Conclusion: This study shows successful radiographic outcome after hallux valgus correction using a tension band construct and allowing immediate full weight-bearing in a surgical shoe in the postoperative period. Significant deformity correction was achieved and maintained and all osteotomies healed. The Re+Line tension band bunion correction system can be safely used as a successful option to fix distal first metatarsal osteotomies, while allowing patients to fully weight bear in a surgical shoe postoperatively and potentially return to activities faster than when using traditional fixation methods. Future studies are needed to assess functional outcomes and patient satisfaction with this novel technique.

Abstract Objective The open Bristow procedure is a long established and effective method for treating anterior shoulder instability. Following the trends of minimally-invasive surgeries, these procedures were performed arthroscopically, and their outcomes were evaluated. Methods A total of 43 shoulders of patients submitted to Bristow procedures by arthroscopy, using a graft positioned horizontally and a screw, with at least two years of postoperative follow-up, were evaluated regarding quality of life, de novo dislocation index, and loss of lateral rotation. Results The mean follow-up time was of 76 months (range: 129 to 24 months). The University of California at Los Angeles (UCLA) score varied from 25.56 ± 0.50 (standard deviation [SD] = 3.25) to 33.23 ± 0.44 (SD = 2.91) (p < 0.0001). Two or more years after surgery, the mean Rowe score was of 94.25 ± 1.52 (SD = 1.34), whereas the good results standard is 75 (p < 0.0001). The mean value for the simple shoulder test was of 11.35 ± 0.21 (SD = 1.34), while the mean value of the lateral rotation loss was of 10.37° ± 1.36° (SD = 8.58°). There were no de novo dislocations.In total, there were 12 complications, 8 of which had no clinical repercussions. The clinically-significant complications included an infection six months after surgery with a potential hematogenous origin, a coracoid fracture that required an intraoperatively procedure change, and two patients with previous impingement who required synthesis material removal more than six months after surgery. Conclusion Although the arthroscopic Bristow procedure was effective in treating anterior shoulder instability, it is not a complication-free surgery.

Introduction: This study aimed to compare the clinical and radiographic results of 28-mm ceramic-on-ceramic (CoC) total hip arthroplasty (THA) to those of 32-mm CoC during a 5- to 15-year follow-up period. Methods: 107 joints (95 women and 6 men) underwent 28-mm CoC, and 60 (49 women and 7 men) underwent 32-mm CoC. The average patient age at the time of surgery was 56.1 and 55.7 years in the 28-mm and 32-mm CoC groups, respectively. Clinical and radiologic measurements of all patients were analysed. Results: The mean preoperative Harris hip score (HHS) was similar in the 2 groups (28-mm, 58.9; and 32-mm, 58.5). However, at final follow-up, the mean HHS of the 32-mm CoC (91.8) was significantly better than that of the 28-mm CoC (88.2) ( p = 0.003), as were the ranges of motion (ROM) for flexion (98.3 ± 13.5° vs. 87.3 ± 19.3°, p < 0.001) and abduction (27.8 ± 14.9° vs. 22.1 ± 19.3°, p = 0.007). The mean wear rate was 0.0044 mm/year for the 28-mm CoC and 0.0044 mm/year for the 32-mm CoC. No ceramic fractures were found in the 2 groups. One joint in the 28-mm CoC (0.9%) required revision owing to progressive osteolysis. Kaplan-Meier survival at 10 years, with implant loosening or revision THA as the endpoint, was 98.3% for 28-mm CoC and 100% for 32-mm CoC ( p = 0.465). Conclusion: There was no significant difference in ceramic-related complications between the 2 groups. Our study demonstrated that the 32-mm and 28-mm CoC are safe and are associated with good clinical outcomes.

Category: Midfoot/Forefoot Introduction/Purpose: Focal damage to articular cartilage and the supporting subchondral plate, commonly referred to as an osteochondral defect (OCD), can be a cause of joint pain and subsequent decreased range of motion. There are few studies specifically describing these lesions in the first metatarsophalangeal (MTP) joint, where they are traditionally grouped into hallux rigidus. There exists an opportunity for early detection and intervention with the intent to prevent deterioration and improve patient outcomes. One contemporary treatment concept is to implant particulated juvenile cartilage allograft to restore articular cartilage. The aim of our study was to review the clinical results of patients that had undergone this procedure for first metatarsal head OCDs. Methods: After IRB approval, a retrospective review of a consecutive case series was studied utilizing the records of three foot and ankle surgeons. Inclusion criteria included all adult patients who were a minimum of one year post surgery and consented to participate. Patient demographics and preoperative visual analog scale (VAS) pain level were recorded from a standardized intake sheet. From the operative note, the OCD size and location was recorded, as well as any concomitant procedures. At a minimum follow up of one year, we obtained objective measurements of arthritis grade and subjective considerations of pain and function, including VAS pain level, Foot Function Index (FFI) questionnaire, the American Orthopaedic Foot and Ankle Society (AOFAS) Hallux Metatarsophalangeal-Interphalangeal scale, and an overall patient satisfaction score. Results: Nine patients met inclusion criteria, 4 males and 5 females. The average age was 41 years old (±11.77, range 21-65). The mean preoperative VAS pain score was 57.50 (±18.32, range 30-80). Four OCDs were located centrally on the first metatarsal head. The average OCD size intraoperatively was 30 mm2 (range 16-49). The average time since surgery was 3.26 years (±1.21, range 1.41-5.62). Average first MTP dorsiflexion was 41.78 degrees (±20.70, range 6-70). The average postoperative hallux rigidus classification was grade 2 (range 1-3). The mean VAS pain score improved to 5.22 (±8.44, range 0-20). The average AOFAS score was 88 (±15.91, range 52-100). The average FFI score was 8.04 (±12.60, range 0-30.6). All but one patient were satisfied or very satisfied with their results. Conclusion: At an average of 3.26 years postoperatively, patients had improved pain, did not show significant progression of their first MTP joint degeneration, and were satisfied with their results. Patients reported very little, if any, limitations in their activity level. We believe that articular damage of the first MTP should be viewed in the same way as OCD lesions in larger joints with emphasis on early detection and treatment to avoid the progression to arthritis. Particulated juvenile cartilage allograft is a valuable tool for surgeons to use in treating focal articular defects of the first metatarsal head.

Object Improved understanding of rod fracture (RF) following adult spinal deformity (ASD) surgery could prove valuable for surgical planning, patient counseling, and implant design. The objective of this study was to prospectively assess the rates of and risk factors for RF following surgery for ASD. Methods This was a prospective, multicenter, consecutive series. Inclusion criteria were ASD, age > 18 years, ≥5 levels posterior instrumented fusion, baseline full-length standing spine radiographs, and either development of RF or full-length standing spine radiographs obtained at least 1 year after surgery that demonstrated lack of RF. ASD was defined as presence of at least one of the following: coronal Cobb angle ≥20°, sagittal vertical axis (SVA) ≥5 cm, pelvic tilt (PT) ≥25°, and thoracic kyphosis ≥60°. Results Of 287 patients who otherwise met inclusion criteria, 200 (70%) either demonstrated RF or had radiographic imaging obtained at a minimum of 1 year after surgery showing lack of RF. The patients' mean age was 54.8 ± 15.8 years; 81% were women; 10% were smokers; the mean body mass index (BMI) was 27.1 ± 6.5; the mean number of levels fused was 12.0 ± 3.8; and 50 patients (25%) had a pedicle subtraction osteotomy (PSO). The rod material was cobalt chromium (CC) in 53%, stainless steel (SS), in 26%, or titanium alloy (TA) in 21% of cases; the rod diameters were 5.5 mm (in 68% of cases), 6.0 mm (in 13%), or 6.35 mm (in 19%). RF occurred in 18 cases (9.0%) at a mean of 14.7 months (range 3–27 months); patients without RF had a mean follow-up of 19 months (range 12–24 months). Patients with RF were older (62.3 vs 54.1 years, p = 0.036), had greater BMI (30.6 vs 26.7, p = 0.019), had greater baseline sagittal malalignment (SVA 11.8 vs 5.0 cm, p = 0.001; PT 29.1° vs 21.9°, p = 0.016; and pelvic incidence [PI]–lumbar lordosis [LL] mismatch 29.6° vs 12.0°, p = 0.002), and had greater sagittal alignment correction following surgery (SVA reduction by 9.6 vs 2.8 cm, p < 0.001; and PI-LL mismatch reduction by 26.3° vs 10.9°, p = 0.003). RF occurred in 22.0% of patients with PSO (10 of the 11 fractures occurred adjacent to the PSO level), with rates ranging from 10.0% to 31.6% across centers. CC rods were used in 68% of PSO cases, including all with RF. Smoking, levels fused, and rod diameter did not differ significantly between patients with and without RF (p > 0.05). In cases including a PSO, the rate of RF was significantly higher with CC rods than with TA or SS rods (33% vs 0%, p = 0.010). On multivariate analysis, only PSO was associated with RF (p = 0.001, OR 5.76, 95% CI 2.01–15.8). Conclusions Rod fracture occurred in 9.0% of ASD patients and in 22.0% of PSO patients with a minimum of 1-year follow-up. With further follow-up these rates would likely be even higher. There was a substantial range in the rate of RF with PSO across centers, suggesting potential variations in technique that warrant future investigation. Due to higher rates of RF with PSO, alternative instrumentation strategies should be considered for these cases.

Medial Release

Background Medial subluxation of the patella is a rare, disabling condition that has iatrogenic and traumatic causation. To date, only open reconstructions have been reported for operative treatment of this condition, but these procedures have a high rate of complications, revisions, and subsequent surgery. This is the first study to present the results of arthroscopic medial retinacular release for treatment of this problem. Hypothesis Arthroscopic release will alleviate painful medial patellar subluxation. Study Design Case series; Level of evidence, 4. Methods Nine knees (7 patients) with painful, recurrent medial subluxation of the patella that occurred spontaneously (2 knees) or after a lateral release (5 knees) or an injury (2 knees) were treated with an arthroscopic medial retinacular release. The retinaculum was released 2 cm medial to the superior pole of the patella down to the anteromedial portal. At a mean follow-up of 2.7 years (range, 1-8 years), all knees were evaluated, and the results were graded according to the Merchant and Mercer rating scale. Results The mean age of the patients was 25 years (range, 15-38 years), and the mean duration of the subluxations before surgery was 28 months (range, 6-48 months). In all 7 patients (9 knees), the medial release relieved their medial subluxation and knee pain, and there were 6 excellent and 3 good results. There were no complications or further realignment surgery needed after this procedure. Conclusion An arthroscopic medial retinacular release will successfully treat painful medial subluxation of the patella.
