Intra-operative peri-articular cocktail injection in inflammatory arthritis patients undergoing total knee arthroplasty

<p class="abstract">Surgical treatment of scaphoid fractures has evolved over the years to include variety of procedures and techniques. However scaphoid middle and distal third fractures fixation with Herbert screw by means of volar approach is a safe and effective method with good functional outcome and union rates. Our study concluded that management of middle and distal third scaphoid fractures with Herbert screw by volar approach gives excellent results in terms of union and recovery to daily activities. The wrist function improvement is more satisfactory, and the incidence of complications is low with this modality of treatment.</p>

CUSTOMIZATION BASED ON CAD AUTOMATION IN PRODUCTION OF MEDICAL SCREWS BY 3D PRINTING

The paper presents a proposal of a complete CAD Automation solution enabling customization of the production of medical screws to individual patient requirements. The proposed approach using OLE technology enables the introduction of customization at the CAD project stage. The assembly of the surgical screw in the PLM system is generated by means of a specially developed application. The application communicates with the SolidEdge system using an API, taking into account 10 different input parameters. Three different types of medical screws have been developed in the application: the Herbert Screw, Cancellous Screw, and Malleolar Screw with three different thread types: rectangular, isosceles, and trapezoidal. The screws designed in this way can be manufactured using 3D printing techniques or CNC machining, and can be used for both humans and animals.

Therapeutic analysis of Herbert screw fixation for capitellar fractures via the anterior approach in adolescent patients

Objective The aim of this study is to analyze the efficacy of open reduction and Herbert screw fixation for coronal fractures of the capitellum via the anterior approach in adolescents. Methods We retrospectively analyzed the clinical and imaging data of 15 adolescents with capitellar fractures who were admitted to our hospital from May 2014 to May 2019. The fracture was reduced through the cubital crease incision via the anterior approach and was internally fixated with Herbert screws. A follow-up was conducted after the operation to examine fracture healing and elbow function. The postoperative functional recovery of patients was evaluated with the Mayo Elbow Performance index (MEPI) and the Broberg-Morrey rating system. Results Patients underwent surgery 3.7 days after injury on average. Intraoperative fracture reduction was satisfactory. No vascular injury or nerve injury occurred. Bony union occurred in an average of 6 weeks after the operation. All adolescents completed a 12- to 36-month follow-up. At the last follow-up, the Mayo Elbow Performance index was considered excellent in 12 patients and good in three patients. The Broberg-Morrey score was considered excellent in 12 patients, good in two patients, and fair in one patient. Conclusion Open reduction with Herbert screw fixation via the anterior approach is a feasible surgical method for the treatment of coronal fractures of the capitellum in adolescents. Levels of evidence Therapeutic, retrospective study-Level IV

Management of a Pipkin Type III Femoral Head Fracture Via Ganz Approach with a Cannulated Lag Screw & Herbert Screw

Objective: To evaluate the medium - to long-term efficacy of a Ganz approach and cannulated lag screw combined with Herbert screw, in the management of a Pipkin type III femoral head fracture.Methods:Retrospective analysis was performed on 11 patients (6 males, 5 females) who sustained Pipkin type III femoral head fractures and were managed with a cannulated lag screw, combined with Herbert screw, inserted using the Ganz approach and who were admitted to our department between June 2018 to June 2020. Perioperative indicators, postoperative function and follow-up complications at 9 months after surgery, Harris score at 6 and 9 months after surgery, Thompson-Epstein score, hip femoral head necrosis and incidence of post traumatic hip arthritis were analysis.Results:10 patients completed follow-up, with an average follow-up time of (13.7 ± 2.1) months. The mean operative time was (100.3 ± 23.67) minutes, intraoperative blood loss was (138.6 ± 50.18) ml, peripheral blood hemoglobin (Hb) was (105.6 ± 18.94) g/L 24 hours after surgery, and the complication rate was 1/10 2 weeks after surgery. The Harris Hip Scores for joint function at 6 and 9 months after the operation were (68.6 ± 5.49) points and (88.8 ± 5.77) points respectively. The excellent and good rate in the last follow-up was 80% (Thompson-Epstein score). The complication rate was 10%.Conclusion:A cannulated lag screw combined with a Herbert screw and inserted via the Ganz approach, is an effective method for the treatment of Pipkin type III fractures.

Therapeutic Analysis of Herbert Screw Fixation for Capitellar Fractures via the Anterior Approach in Children

Objective: To analyse the efficacy of open reduction and Herbert screw fixation for coronal fractures of the capitellum via the anterior approach in children.Methods: We retrospectively analysed the clinical and imaging data of 15 children with capitellar fractures who were admitted to our hospital from May 2014 to May 2019. The fracture was reduced through the cubital crease incision via the anterior approach and was internally fixated with Herbert screws. A follow-up was conducted after the operation to examine the fracture healing and elbow function. The postoperative functional recovery of patients was evaluated with the Mayo Elbow Performance index (MEPI) and the Broberg-Morrey rating system.Results: Patients underwent surgery 3.7 days after injury on average. Intraoperative fracture reduction was satisfactory. No vascular injury or nerve injury occurred. Bony union occurred in an average of 6 weeks after the operation.

The Broberg-Morrey score was considered excellent in 12 patients, good in two patients, and fair in one patient. Conclusion: Open reduction and Herbert screw fixation via the anterior approach are an ideal surgical method for the treatment of coronal fractures of the capitellum in children.Levels of Evidence: Therapeutic, retrospective study-Level IV

Short-term Outcomes of Herbert Screw Fixation for Isolated Olecranon Fractures in Children: a Single-institution Retrospective Study

Background: Although various fixation methods can be used for the treatment of displaced olecranon fractures, there are no clear indications in the current literature regarding which surgical technique should be adopted. In this study, we evaluated the clinical and radiological outcomes of closed reduction with percutaneous Herbert screw fixation in children with isolated olecranon fractures.Methods: We retrospectively reviewed the records of children treated at our center for isolated olecranon fractures (Mayo type IIA) with closed reduction and percutaneous Herbert screw fixation between January 2016 and December 2018. Radiographic assessment of fracture healing was performed 6–8 months postoperatively and included assessment for loss of reduction and maximum length of the ulna. Clinical outcomes included elbow flexion and extension, forearm pronation and supination, short version of the Disabilities of the Arm, Shoulder, and Hand (QuickDASH) score, and complications. The Herbert screws were removed by a second operation.Results: A total of 14 patients with an average age at the time of injury of 11.36 (range, 10–14) years were included. All patients had good radiological and clinical outcomes at 6–8 months postoperatively; all had normal elbow ranges of motion and showed complete bone healing on radiographs. There were no cases of foreign body irritation, implant migration, or osteoarthritis. Premature epiphyseal closure was noted in six patients. The average QuickDASH score was 1.58. Conclusions: Fixation of olecranon fractures with Herbert screws is a safe and easy fixation method in young patients, leading to good functional and radiological results. Nonetheless, determination of the effects of this treatment method on the olecranon ossification center requires long-term follow-up.
