Surgical treatments of patients with periprosthetic humeral fracture and comorbidities

Background: Periprosthetic humeral fractures represent a complex and rare complication. Currently, there is no standardized procedure for management or classification of these fractures. Questions/purposes: This unique case series purpose was to look at surgical outcomes and comorbidity profiles of 10 PHF patients. Subsequent analysis looked at whether these outcomes could add to the discussion of a proposed standard of care in a patient cohort with significant comorbidities. Patients and methods: All patients with humeral fractures from 2008-2019 were analyzed for inclusion. A total of ten patients met the inclusion criteria; humeral fracture concurrent with a shoulder arthroplasty. Each patient was managed surgically using a locking plate with or without cerclage wiring. Outcome analysis was then performed for each patient. Humoral fractures managed conservatively were removed from the dataset along with periprosthetic fractures around an elbow arthroplasty, IM nail, or supracondylar fracture after shoulder arthroplasty. Results: The average union time in all patients was 13.27±2.90 (9.86-17.29) weeks. There was no significant difference between patients treated with cerclage wiring or without. All patients had successful union except for a patient with Osteogenesis Imperfecta. There were two radial nerve palsies. The average Deyo-Charlson score and BMI was 7.1±.84 (4-13) and 29.89 respectively. Conclusion: The treatment of PHFs using the technique of ORIF with locking plate with or without cerclage wiring provides satisfactory outcomes in a patient population that usually includes significant comorbidities.

Background Finite element analysis has suggested that stemless implants may theoretically decrease stress shielding. The purpose of this study was to assess the radiographic proximal humeral bone adaptations seen following stemless anatomic total shoulder arthroplasty. Methods A retrospective review of 152 prospectively followed stemless total shoulder arthroplasty utilizing a single implant design was performed. Anteroposterior and lateral radiographs were reviewed at standard time points. Stress shielding was graded as mild, moderate, and severe. The effect of stress shielding on clinical and functional outcomes was assessed. Also, the influence of subscapularis management on the occurrence of stress shielding was determined. Results At 2 years postoperatively, stress shielding was noted in 61 (41%) shoulders. A total of 11 (7%) shoulders demonstrated severe stress shielding with 6 occurring along the medial calcar. There was one instance of greater tuberosity resorption. At the final follow-up, no humeral implants were radiographically loose or migrated. There was no statistically significant difference in clinical and functional outcomes between shoulders with and without stress shielding. Patients undergoing a lesser tuberosity osteotomy had lower rates of stress shielding, which was statistically significant ( p = 0.021) Discussion Stress shielding does occur at higher rates than anticipated following stemless total shoulder arthroplasty, but was not associated with implant migration or failure at 2 years follow-up.

BACKGROUND: This study compared the clinical and radiological outcomes of the single calcar screw plate and Polarus nail techniques for the treatment of the proximal humerus fractures.METHODS: Seventy-two patients diagnosed with displaced proximal humerus fracture were enrolled for the study. Of these, 50 patients underwent the locking plate surgery with a single calcar screw (plate group), whereas 22 patients underwent the Polarus nail surgery (nail group). The plate group was further divided into plate 1 group (with medial support), and plate 2 group (without medial support). The radiological and functional results of both groups were compared to the nail group.RESULTS: The α angle 1 year after surgery was significantly different between plate 1 and plate 2, and plate 2 and nail groups (p=0.041, p=0.043, respectively). The ratio that does not satisfy the reference value of γ angle was 2.8% in plate 1, 7.1% in plate 2 and 22.7% in nail group (p=0.007); there was a significant difference between plate 1 and nail group, and plate 2 and nail group (p=0.014, p=0.033, respectively).CONCLUSIONS: No significant differences were observed in the clinical results between locking plate and Polarus nail. However, in the plate 2 group and nail group, the rate of failure to maintain reduction during the 1-year period after surgery was statistically and significantly higher than the plate 1 group (level of evidence: level IV, case series, treatment study).

Background: The purpose of this study was to evaluate the clinical and radiologic outcomes of patients younger than 20 years, treated with the arthroscopic-talus autologous matrix-induced chondrogenesis (AT-AMIC) technique and autologous bone graft for osteochondral lesion of the talus (OLT). Methods: Eleven patients under 20 years (range 13.3-20.0) underwent the AT-AMIC procedure and autologous bone graft for OLTs. Patients were evaluated preoperatively (T0) and at 6 (T1), 12 (T2), and 24 (T3) months postoperatively, using the American Orthopaedic Foot & Ankle Society Ankle and Hindfoot (AOFAS) score, the visual analog scale and the SF-12 respectively in its Mental and Physical Component Scores. Radiologic assessment included computed tomographic (CT) scan, magnetic resonance imaging (MRI) and intraoperative measurement of the lesion. A multivariate statistical analysis was performed. Results: Mean lesion size measured during surgery was 1.1 cm3 ± 0.5 cm3. We found a significant difference in clinical and radiologic parameters with analysis of variance for repeated measures ( P < .001). All clinical scores significantly improved ( P < .05) from T0 to T3. Lesion area significantly reduced from 119.1 ± 29.1 mm2 preoperatively to 77.9 ± 15.8 mm2 ( P < .05) at final follow-up as assessed by CT, and from 132.2 ± 31.3 mm2 to 85.3 ± 14.5 mm2 ( P < .05) as assessed by MRI. Moreover, we noted an important correlation between intraoperative size of the lesion and body mass index (BMI) ( P = .011). Conclusions: The technique can be considered safe and effective with early good results in young patients. Moreover, we demonstrated a significant correlation between BMI and lesion size and a significant impact of OLTs on quality of life. Level of Evidence: Level IV, retrospective case series.

Background The purpose of this investigation was to compare rates of filled opioid prescriptions and prolonged opioid use in opioid naïve patients undergoing total shoulder arthroplasty (TSA) in inpatient versus outpatient settings. Methods A retrospective cohort study was conducted using a national insurance claims database. Inpatient and outpatient cohorts were created by identifying continuously enrolled, opioid naïve TSA patients. A greedy nearest-neighbor algorithm was used to match baseline demographic characteristics between cohorts with a 1:1 inpatient to outpatient ratio to compare the primary outcomes of filled opioid prescriptions and prolonged opioid use following surgery between cohorts. Results A total of 11,703 opioid naïve patients (mean age 72.5 ± 8.5 years, 54.5% female, 87.6% inpatient) were included for analysis. After propensity score matching (n = 1447 inpatients; n = 1447 outpatients), outpatient TSA patients were significantly more likely to fill an opioid prescription in the perioperative window compared to inpatients (82.9% versus 71.5%, p < 0.001). No significant differences in prolonged opioid use were detected (5.74% inpatient versus 6.77% outpatient; p = 0.25). Conclusions Outpatient TSA patients were more likely to fill opioid prescriptions compared to inpatient TSA patients. The quantity of opioids prescribed and rates of prolonged opioid use were similar between the cohorts. Level of evidence Therapeutic Level III.

Background: In an effort to minimize narcotic analgesia and its potential side effects, anti-inflammatory agents offer great potential provided they do not interfere with bone healing. The safety of ketorolac administration after foot and ankle surgery has not been well defined in the current literature. The purpose of this study was to report clinical healing and radiographic outcomes for patients treated with a perioperative ketorolac regimen after open reduction and internal fixation (ORIF) of ankle fractures. Methods: A retrospective review was performed on all patients that received perioperative ketorolac at the time of lateral malleolar, bimalleolar, and trimalleolar ankle ORIF by a single surgeon between 2010 and 2016 with minimum 4 months follow-up. Patients received 20 tablets of 10 mg ketorolac Q6 hours. Radiographs were evaluated independently by 2 blinded fellowship-trained orthopedic foot and ankle surgeons to assess for radiographic healing. A total of 281 patients were included, with a median age of 51 years and 138 males (47%). Statistical analysis consisted of a linear mixed-effects regression. Results: In all, 265/281 (94%) were clinically healed within 12 weeks and 261/281 (92%) were radiographically healed within 12 weeks. Within the group of patients that did not heal within 12 weeks, mean time to clinical healing was 16.9 weeks (range = 14-25 weeks), and mean time to radiographic healing was 17.1 weeks (range = 14-25 weeks). In patients taking ketorolac, there were no cases of nonunion in our series (n = 281) and no significant difference found between fracture patterns and healing or complications ( P = .500). Conclusions: Perioperative ketorolac use was associated with a high rate of fracture union by 12 weeks. This is the first study to examine the effect of ketorolac on radiographic time to union of ankle fractures. Additional studies are necessary to determine whether ketorolac helps reduce opioid consumption and improve pain following ORIF of ankle fractures. Level of Evidence: Level IV, case series.

ABSTRACT Objective It is difficult to achieve proper alignment after total knee arthroplasty (TKA) in patients with extra-articular deformity (EAD) because of altered anatomical axis and distorted landmarks. As of this writing, only case series have been reported with regard to the usefulness of computer-assisted navigation systems for TKA with EAD. This study therefore compared outcomes in TKA with EAD, with and without navigation. Methods Fourteen osteoarthritis patients with EAD due to previous fracture malunion or operations were assessed. Seven TKAs were performed with navigation (navigation group) and another 7 were performed without navigation (manual group). Clinical and radiographic outcomes were compared before and two years after surgery. Results The mean postoperative Knee Society function score was significantly higher in the navigation group. No significant difference was found in postoperative range of motion and Knee Society knee score. The rate of outliers in radiographic outcomes tended to be lower in the navigation group. Conclusion Better clinical outcomes were achieved in cases in which navigation was used. Computer-assisted navigation is useful in TKA for patients with EAD.

Background: The aim of this study was to compare the safety and efficacy of primary trabeculectomy with mitomycin C and Ahmed glaucoma valve (AGV) implantation in patients with Fuchs heterochromic iridocyclitis (FHIC)-related glaucoma, a rare complication of an uncommon form of uveitis. Methods: In this retrospective comparative case series, 26 FHIC-associated glaucoma patients received trabeculectomy (n=12) or an AGV (n=14). Primary outcome measures were surgical success, defined as intraocular pressure (IOP) ≤21 mmHg, decreasing ≥20% from baseline, and no secondary glaucoma surgery. Secondary outcome measures were the number of glaucoma medications, complications, best corrected visual acuity (BCVA), and IOP. Results: The follow-up was 34.0±17.7 months in patients that received trabeculectomy and 33.4±18.6 months in AGV (P= 0.837). The cumulative probability of success rate was 41.7% for trabeculectomy and 85.7% for AGV, with no significant difference in complications (P>0.05). The IOP in patients that received trabeculectomy dropped from 23.4±3.3 mmHg to 21.6±5.2 mmHg at the final visit (P= 0.041). In patients that received AGV, the IOP decreased from 24±7.8 to 17.1±2.6 mmHg (P= 0.003). The number of glaucoma medications at baseline were 3.3±0.5 in those that received trabeculectomy and 3±0.6 in those that received AGV (P=0.233), and decreased to 2.4±1.0 (P=0.008) and 1.7±0.6 (P=0.002), respectively. BCVA was equal in both groups and did not change (P>0.05). Conclusion: Primary AGV had a higher success rate than trabeculectomy, with patients also needing fewer medications for the management of FHIC-associated glaucoma.

Abstract Background Currently, the reduction and support of comminuted medial cortex of humeral fracture remains a challenge, Therefore, a novel reduction and fixation technique that employs an anteromedial small locking plate was explored in this study, and its viability and the associated complications were assessed. Methods Fifteen cases of proximal humeral fractures with medial instability (five cases were classified as three-part and ten as four-part by Neer classification) were treated by the proposed reduction technique using an anteromedial small locking plate. Subsequently, the radiological and clinical outcomes were evaluated over an average follow-up period of 18.53 months. Results The average operation time was 108 minutes (range, 70–130 minutes), and the mean fracture union time in all patients was 12.13 weeks (range, 8–16 weeks). Complications such as infection and neurovascular injury were not observed. Postoperative X-ray showed avascular necrosis and screw penetration in one patient, while screw penetration, varus malunion, or significant reduction loss was not found in the other cases. The mean Constant score was 79.8 (range, 68–92) during the final visit. Conclusions The use of an anteromedial small locking plate improved the reduction efficiency, reconstructed the medial support, and alleviated the occurrence of complications in proximal humeral fractures with medial instability.

Obtaining a spine that is well balanced after fusion for scoliotic deformity is primordial for the patients’ quality of life. A simple T-shaped instrument combined with standard intraoperative fluoroscopy can be of great help to evaluate the coronal alignment quickly. The aim of this study was to evaluate if a T-shaped device could predict the postoperative coronal balance. Before finalization of the rod fixation, the balance was checked by verifying the relationship between the T-shaped instrument and the upper instrumented vertebra (UIV), and final adjustments were made to correct the coronal balance. A retrospective study was conducted on 48 patients who underwent surgery to correct scoliotic deformity. Intraoperative and postoperative coronal alignment was measured independently by two observers. The mean intraoperative horizontal offset measured between T-shaped instrument and the center of the UIV was 1,69mm to the right with a standard deviation (SD) of 12,43 mm. On postoperative full spine radiographs, the mean offset between the centra sacral vertical line and the center of the UIV was 2,44mm to the left with a SD of 13,10mm. There is no significant difference in coronal balance between both measurements (p=0,12). With this technique we were able to predict the postoperative coronal balance in all but one patient (97,92%). We conclude that the use of a simple T-shaped instrument can provide adequate intraoperative assessment of coronal balance in correcting scoliotic deformity. Level of evidence : IV – case series

Objective: To compare the Portuguese translations of the Foot and Ankle Activity Measure (FAAM) and the Foot and Ankle Outcome Score (FAOS) questionnaires as functional assessment instruments for patients with hallux valgus and assess correlations between scores and severity of deformity. Methods: A total of 28 patients were assessed and the functional scores provided by the FAAM and FAOS questionnaires were compared and their correlations with clinical and radiological severity were analyzed. Results: Mean age was 46.88 years (range: 18 to 64). Laterality was distributed as follows: 57.1% had the deformity on the right foot (16 cases) and 42.9% on the left (12 cases). The deformities identified were graded as follows: 26.1% of patients had mild deformity (6 cases), 45.3% had moderate deformity (14 cases), and 28.6% had severe deformity (8 cases). It was observed that the distribution of scores for the different grades of deformity was the same for both questionnaires. Conclusion: There was no significant difference between the results obtained using the FAAM or the FAOS questionnaire or in the relationship of proportionality between radiological deformity grade and the functional scores obtained using the two tests.
