Our rationale is that Blount disease has a bony and ligamentous laxity element of the lateral collateral ligament that can be corrected simultaneously through hemiepiphysiodesis of the tibia and epiphysiodesis of proximal fibula physis by cannulated screws. Patients and Methods: This is a retrospective study conducted on 23 limbs with tibia vara treated between 2010 and 2017 followed up for 2 to 6 years. Ages ranged from 9 to 13 years with a late-onset type of Blount disease. We used a percutaneous transphyseal fully threaded screws traversing the proximal tibial lateral hemiepiphysis, and another screw inserted traversing the proximal fibular epiphysis. Results: There was a statistically significant improvement of the radiographic parameters, especially in the form of joint line congruence angle in both supine and standing positions. All patients were clinically and radiographically completely corrected without complications, except 1 patient with a surgical site superficial infection, treated medically. Conclusion: Fibular-guided growth surgery with lateral proximal tibia epiphysiodesis is a minimally invasive technique that improves the corrective power of hemiepyphysiodesis of the posterolateral compartment of the knee.

Growth arrest of the medial part of the epiphysis leads to varus deformity of the distal tibia and fibular overgrowth. If the deformity is left untreated, the malalignment may lead to irreversible damage and early ankle joint osteoarthritis in the long term. Several surgical techniques have been described in the literature to achieve correction and prevent late complications. These include the closure of the remaining epiphysis and various osteotomies around the ankle, using internal and external fixation. Materials and Methods: We report a technique that includes medial open wedge supramalleolar osteotomy, insertion of a structural cortical allograft and fixation with an anatomically contoured locking plate, completion of closure of the distal tibial physis, and distal fibular epiphysiodesis to prevent tibiofibular relations distortion. Part of this protocol is osteotomy of the distal fibula to prevent excessive pressure on the talus, and at the end of the operation, fibular fixation should be performed as well. In children with open physis and potential for significant leg length discrepancy, we recommend closure of the contralateral physis of the distal tibia and fibula. To the best of our knowledge, precise details of this protocol have not been described. Conclusion: We believe that this protocol is a reliable, accurate, and relatively simple method that provides not only anatomic correction and restoration of the ankle joint to prevent early ankle and subtalar arthritis but also addresses late complications, such as ipsilateral fibular overgrowth and limb length discrepancy.","PeriodicalId":45336,"journal":{"name":"Techniques in Orthopaedics","volume":null,"pages":null},"PeriodicalIF":0.3,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90548814","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Current recommendations support the use of leukocyte-poor PRP for OA and leukocyte-rich PRP for tendinopathy. If a patient presents with both OA and tendinopathy, very few systems can create multiple PRP products in the same treatment session. The Angel device processes multiple cycles to produce different PRP products. Methods: Ten healthy volunteers donated 156 mL whole blood (WB) that was mixed with 24 mL of anticoagulant citrate dextrose solution, solution A. The first PRP was produced by processing 120 mL at the 0% hematocrit setting and the second PRP was created by processing the remaining 60 mL at the 15% hematocrit setting. WB and PRP underwent complete blood counts and growth-factor analysis. Results: Ten patients donated WB for processing. The 0% setting yielded 3.7 ± 0.15 mL PRP, whereas the 15% setting produced 4.7 ± 0.33 mL. The 0% and 15% settings both concentrated platelets significantly more than WB (1101.5 ± 281.7 K/uL and 1357.8 ± 363.7 vs 184.3 ± 39.1 K/uL, P = 0.000). The 0% setting reduced total leukocytes, but this was not statistically significant. The 15% setting concentrated total leukocytes to 24 ± 8.72 K/uL, which was significantly higher than WB (P = 0.000). Neutrophil concentration was significantly reduced in the 0% PRP compared with 15% (0.032 ± .02 vs 6.75 ± 5.76 K/uL, P = 0.000). Discussion: Two unique PRP products were created from the same batch of WB using a single commercial kit by processing aliquots at different settings.","PeriodicalId":45336,"journal":{"name":"Techniques in Orthopaedics","volume":null,"pages":null},"PeriodicalIF":0.3,"publicationDate":"2023-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74256880","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These injuries are difficult to stabilize due to significant shear forces acting on the fracture site. Their treatment is challenging and with high risks of complications, such as fixation failure, malunion, nonunion, and avascular necrosis of the femoral head. Material and Methods: It compared the biomechanical stability provided by 3 different fixation methods: (1) dynamic hip screw with derotation screw, (2) cannulated screws with a conventional medial bone plate, and (3) cannulated screws with a locked medial bone plate. These fixation structures were applied on fourth-generation medium-sized synthetic bones, with a 17 pound per cubic foot cellular foam core and cervico-diaphyseal angle of 120 degrees were used. The comparison was performed through biomechanical tests under cyclic loading followed by an ultimate load. The interfragmentary movement at the fracture site was the main variable for the cyclical phase. Results: The biomechanical comparison showed no statistical differences (P > 0.05) in stiffness, micromovement level, and mechanical resistance among the fixation techniques evaluated. Discussion: To stabilize the vertical femoral neck fracture in young patients, the use of a medial bone plate associated with cannulated screws on a “tie-rod” assembly is an option that supports the mechanical demand until the fracture healing. The locked medial plate did not provide an advantage compared with the conventional bone plate.","PeriodicalId":45336,"journal":{"name":"Techniques in Orthopaedics","volume":null,"pages":null},"PeriodicalIF":0.3,"publicationDate":"2023-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72907798","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Maintenance of skeletal traction during imaging procedures can be a large burden on providers, and releasing traction even for a short period of time can have significant adverse outcomes for patients. There is currently no practical technique for accomplishing this in the literature. Materials and Methods: We describe here a novel and easily reproducible setup that allows for the maintenance of traction during computed tomography scans. Results: The described technique is versatile as it can be used with different computed tomography scanners, easily assembled in a few minutes, and accommodates up to 25 lbs. Conclusions: This technical design offers a safe and quickly reproducible setup for skeletal traction in unique situations where traction is required during imaging. The apparatus has implications for advanced diagnostic and research-based imaging as well, and all materials should be readily available at any institution frequently performing skeletal traction.","PeriodicalId":45336,"journal":{"name":"Techniques in Orthopaedics","volume":null,"pages":null},"PeriodicalIF":0.3,"publicationDate":"2023-02-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80164073","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
