Quantitative Volumetric Measurements of Bone Grafting Sites Within the Lower Extremity on Computed Tomography Scans.

The anterior iliac crest is one of the most used options; however, pain and other complications have been reported. Other options for bone harvest in the lower extremity, such as the proximal tibia and calcaneus, can be useful sites for bone grafting. Computed tomography angiography images of the lower extremity were analyzed using 3-D Slicer™ medical imaging software, creating an advanced 3-dimensional model. Bone volume (cm3) and bone mineral density (Hounsfield units) were measured from the cancellous bone in the anterior iliac crest, posterior iliac crest, proximal tibia, and the calcaneus. Fifteen studies were included. The total volume measured it was of 61.88 ± 14.15 cm3, 19.35 ± 4.16 cm3, 32.48 ± 7.49 cm3, 26.40 ± 7.18 cm3, for the proximal tibia, anterior and posterior iliac crest, and calcaneus, respectively. Regarding Hounsfield units, the densities were 116 ± 58.77, 232.4 ± 68.65, 214.4 ± 74.45, 170.5 ± 52.32, for proximal tibia, anterior and posterior iliac crest, and calcaneus. The intraclass correlation coefficients were in average >0.94. In conclusion, the proximal tibia has more cancellous bone than the anterior and posterior iliac crest. The calcaneus has more cancellous bone than the anterior iliac crest. Bone mineral density was highest in the anterior iliac crest and in proximal tibia was the lowest value.

Comparison of Anterior Iliac Crest Versus Proximal Tibia Autologous Bone Graft Harvesting: A Systematic Review and Meta-Analysis.

Anterior iliac crest (AIC) is the preferred option for bone grafting; however, pain and complications are reported. Proximal tibia (PT) is a sourceful site for bone grafting with lower complications. MEDLINE, EMBASE, and Scopus were searched to identify studies comparing AIC and PT autograft procedure. The main outcome was pain and complication rate. As well as cadaveric and cell-based studies were analyzed for quantity and quality of AIC and PT autograft. A meta-analysis was performed using the generic inverse variance method with random or fixed effects model depending on heterogeneity between studies. Heterogeneity was tested with the I2 statistic index. Fifteen studies were included in the meta-analysis. Six studies and 248 patients were included for clinical outcomes. A significant pain reduction favoring PT at 24 hours was detected after meta-analysis and corresponding sensitivity analysis. The estimated effect size ranged from -2.31 to -2.93 cm, with confidence intervals aligned to the left indicating a robust steady decrease in pain across studies. This effect was not observed after 1 month. A total of 18 complications were reported, 13 in the AIC group and 5 in the PT group. Four cadaveric studies were included, 3 favored PT on the quantity of bone graft harvested. Five cell-based studies were included, only one study favored AIC for quality of bone graft. Our study concludes that PT bone harvest is a reliable option for bone grafting regarding morbidity, complications, volume graft obtained, and cellular and molecular properties. However, the current evidence is still insufficient to draw definitive conclusions, especially in terms of bone healing. PROSPERO Register: CRD42020198150.

Open Inferior glenohumeral joint dislocation with complete range of motion recovery: Case Report and literature review.

Luxatio erecta is an inferior glenohumeral dislocation. It is an uncommon pathology with a prevalence of 0.5% of all shoulder dislocations. An open luxatio erecta presentation is rarer. After an extensive literature search, we only could find three complete case reports. From these cases, 2 out of 3 developed complications such as infections and severely limited range of motion, especially in flexion and abduction. We report the case of a 39-year-old man with an open inferior glenohumeral joint dislocation with complete rotator cuff tear and fracture of the greater tuberosity secondary to a motor vehicle accident. He was treated with open reduction, glenohumeral capsulorrhaphy, and transosseous rotator cuff repair with good clinical outcome. In conclusion, an open inferior shoulder dislocation is rare, less than 0.1% of all dislocations, with a high incidence of nerve injury. We suggest prompt surgical treatment with immediate administration of antibiotic therapy, wound debridement, irrigation, open reduction, and repair of the rotator cuff as an adequate protocol and focused rehabilitation with early mobilization of the glenohumeral joint.

Comparison of open arthrotomy versus arthroscopic surgery for the treatment of septic arthritis in adults: a systematic review and meta-analysis.

PURPOSE: To evaluate the efficacy of arthrotomy, when compared with arthroscopy, in the treatment of adults with septic arthritis of any joint. METHODS: MEDLINE, EMBASE, and Scopus were searched to identify studies comparing arthrotomy and arthroscopy as therapeutic approaches in patients with septic arthritis of any joint. The main outcome was the re-infection rate. A meta-analysis was performed using the generic inverse variance method with random or fixed effects model depending on heterogeneity between studies. Heterogeneity was tested with the I2 statistic index. RESULTS: Twenty studies with 10,249 patients treated by arthrotomy or arthroscopy were evaluated. We observed a significant lower risk of re-infection (odds ratio [OR], 1.35 [95% CI, 1.16-1.58]; p = 0.0002) and complications (OR, 1.32 [95% CI, 1.12-1.55]; p = 0.001) rate as well as less hospital stay (mean difference [MD], 0.57 days [95% CI, 0.10-1.05]; p = 0.02) favouring arthroscopic intervention. The subanalysis indicated that patients with knee (OR, 1.50 [95% CI, 1.17-1.92]; p = 0.001) and shoulder (OR, 1.24 [95% CI, 1.00-1.53]; p = 0.04) septic arthritis intervened by arthrotomy had a higher risk of re-infection. A lower number of hospitalization days (MD, 0.89 days [95% CI, 0.31-1.47]; p = 0.003) and a lower risk for complications (OR, 1.26 [95% CI, 1.04-1.52]; p = 0.02) were observed in patients treated with arthroscopy after septic knee arthritis. CONCLUSIONS: Available evidence suggests that patients with septic arthritis of the knee and shoulder treated by arthroscopy have less risk of re-infection than those treated by arthrotomy. The quality of the body of evidence is still insufficient to reach reliable conclusions. PROSPERO TRIAL REGISTRATION NUMBER: CRD42020176044. Date registration: April 28, 2020.

Repair of the Posterior Lateral Meniscal Root Tear: Suture Anchor Fixation Through the Outside-In Anterior Cruciate Ligament Reconstruction Femoral Tunnel.

Posterior lateral meniscus root tears are defined as tears that occur within 9 mm of the posterior lateral meniscus insertion or as avulsions of the insertion. If root tears are left unrepaired, functional alterations and early degenerative changes occur in the affected compartment. Several surgical techniques have been described to reattach the posterior horn of the lateral meniscus, including transtibial pull-out technique and side-to-side repair technique. This surgical technique reports an alternative way to repair posterior lateral meniscus root tears that are associated with or without an anterior cruciate ligament graft tear. The technique involves the placement of a suture anchor on the lateral meniscus root footprint through the outside-in anterior cruciate ligament femoral tunnel, which minimizes the possibility of iatrogenic lesions and facilitates repair.

Double-Row Rotator Cuff Repair Enhanced With Platelet-Rich Therapy Reduces Retear Rate: A Systematic Review and Meta-analysis of Randomized Controlled Trials.

PURPOSE: To assess retear rates in arthroscopic double-row rotator cuff repair (double-row RCR) with and without platelet-rich therapy (PRT). METHODS: Systematic review and meta-analysis of randomized controlled trials (RCTs). MEDLINE, Embase, and Scopus databases were searched for RCTs involving use of PRT exclusively in arthroscopic double-row RCR. A random-effects model and the generic inverse variance method were used for quantitative data synthesis. Heterogeneity was tested with the I2 statistic index. RESULTS: The 9 RCTs included in the meta-analysis demonstrated a risk reduction of 49% for retears in patients receiving PRT (risk ratio [RR] 0.51; 95% confidence interval [CI] 0.35 to 0.76; P = .0008; I2 = 0%). Divided by tear sizes, retear risk reduction of 47% (RR 0.53; 95% CI 0.30 to 0.95; P = .03; I2 = 0%) was found in small to medium tears and 51% (RR 0.49; 95% CI 0.29 to 0.84; P = .009; I2 = 0%) in large to massive tears. Linked double-row RCR resulted in risk reduction of 51% for retears in comparison with nonlinked repairs. CONCLUSION: Double-row RCR plus PRT significantly reduced retear rates in all sizes of rotator cuff tears. Linked double-row RCR and applying the PRT during the surgical procedure and in the tendon-bone interface reproduced the best outcomes. Clinically, all patients improved, and no statistically significant difference was seen in clinical and functional scores between the intervention groups. All patients achieved optimal values for patient-reported outcomes measures. LEVEL OF EVIDENCE: I, systematic review and meta-analysis of level I studies.

Surgical Management of a Latissimus Dorsi Costal Tear in an Elite Female Handball Player: A Case Report.

Introduction: Latissimus dorsi ruptures are rare injuries more commonly seen in elite overhead and hip throwers athletes. The most frequent mechanism of injury is indirect. The management of these injuries is unclear and controversial. Case Presentation: In this case report we present a professional female handball player with an acute intramuscular/costal tear of the latissimus dorsi, managed operatively. The patient injured extremity was the dominant throwing arm with a palpable muscle gap of 3 cm. Operative treatment was taken and objective follow-up using UCLA shoulder rating scale and DASH scores; demonstrating a progressive improvement between day zero (UCLA 13pts and DASH 36.7 pts) and the final 6 months (UCLA 33pts and DASH 0.8 pts) follow up; returning to sport at 12 weeks. Conclusion: Latissimus dorsi costal tears are uncommon injuries that can also be seen in hip throwing athletes. Surgical management should be considered if the dominant arm is affected and a 3cm muscle gap is present.

Clinical efficacy of platelet-rich plasma in the treatment of lateral epicondylitis: a systematic review and meta-analysis of randomized placebo-controlled clinical trials.

To compare the effects of platelet-rich plasma (PRP) injection versus placebo (saline injection) on pain and joint function in lateral epicondylitis in randomized placebo-controlled trials. Randomized controlled trials that evaluated pain (visual analog scale [VAS] and patient-rated tennis elbow evaluation [PRTEE]) and/or functional improvement (PRTEE; disability of the arm, shoulder, and hand [DASH]; and Roles-Maudsley score [RMS]) in patients diagnosed with lateral epicondylitis and compared PRP with placebo injections were considered. The MEDLINE, EMBASE, Web of Science, and Scopus databases were searched from inception to October 2019. The assessment of bias was performed using the Cochrane Risk of Bias Tool version 1. The meta-analysis was conducted with a random effects model and generic inverse variance method. Five trials involving a total of 276 individuals were included. They used a parallel study design and saline solution as placebo. The mean age of participants was 48.0 ± 9.3 years. Follow-up varied from 2 months to 1 year. No significant changes were noted for pain (standardized mean difference [SMD], - 0.51 [95% confidence interval (CI), - 1.32 to - 0.30]) nor functional scores (SMD, - 0.07 [95% CI, - 0.46 to 0.33]) between PRP and placebo injections. The most frequent adverse reaction reported in two of the five studies was transient post-injection pain for a few days (from 16 to 20% in the PRP group and from 8 to 16% in the placebo group). PRP injection was not superior to placebo for relieving pain and joint functionality in chronic lateral epicondylitis. However, patients reported improvement after both interventions in such clinical parameters. Further randomized trials are required to determine whether PRP injection is clinically more effective than placebo (saline injection).

Performance of the international classifications criteria for autoimmune hepatitis diagnosis in Mexican patients.

The revised score of the International Autoimmune Hepatitis Group (R-IAIHG) and the simplified criteria (SC) are used for diagnosis of autoimmune hepatitis (AIH). Our aim is to evaluate the performance of these classifications to differentiate AIH from other autoimmune liver diseases. The frequency of diagnosis of definite AIH was similar both by the R-IAIHG and the SC systems (41% versus 40%), whereas diagnosis of probable AIH was made more commonly by the R-IAIHG than the SC (59% versus 29%), and 23 patients that have been graded as definite (n = 7) or probable (n = 16) AIH by the R-IAIHG had non-diagnostic scores by the SC system. The scoring systems rendered concordant diagnosis of definite (n = 15) and probable (n = 13) AIH in 28/73 patients (38%). Discordant diagnoses of AIH were rendered in 45/73 patients (62%). The R-IAIHG exhibited a sensitivity of 95%, specificity of 90%, and positive predictive value (PPV) and negative predictive value (NPV) of 93% for both. On the other hand, the SC had a lower sensitivity (65%) but a higher specificity (100%), PPV of 100%, and NPV of 68%. In conclusion, both international scoring systems diagnosed the same number of cases as definite AIH. The R-IAIHG showed a higher sensitivity in diagnosing AIH, whereas the SC showed a higher specificity. SC are easier to apply at the bedside and exclude more patients that could have a different etiology.
