Glenoid reconstruction bone loss with a pediculated coracoid autograft during shoulder arthroplasty. A technical note.

Reconstruction of glenoid bone loss is a difficult but often required component of shoulder arthroplasty. A variety of free autografts or allografts have been proposed for reconstruction. While Latarjet is well accepted for the management of anterior instability, the use of a coracoid graft has not been described in conjunction with shoulder arthroplasty. We propose that anterior and central glenoid bone defects can be reconstructed with the coracoid process. to provide a vascularized local structural autograft. Level of evidence: IV.

Chondrosarcoma of the proximal radius treated by wide resection and reconstructed by 3D printed implant: A case report and description of surgical technique.

INTRODUCTION: Chondrosarcoma is the second most common primary malignancy of bone that can occur in multiple locations in the skeleton. It has been rarely reported in the proximal radius. While surgical resection is the primary treatment modality for individuals with localized disease, reconstruction can be challenging in the elbow joint due to its complex anatomy. 3D printing technology can be used in such complex cases to restore the normal anatomy after resection. CASE PRESENTATION: We present a case of mesenchymal chondrosarcoma in a 33-year-old male occurring in the proximal radius, restricting his elbow motion. That was resected and reconstructed using 3D modeling. Restoring a functional range of motion without instability. DISCUSSION: Many surgical options for chondrosarcoma presented over the years including en bloc resection, resection with or without reconstruction, or amputation. Usage of 3D modeling in the orthopedic surgery field is relatively new and it can be used in pre-operative planning and shortens surgical time. 3D printing in our case helped in obtaining a full range of motion (flexion, extension, pronation, and supination) for the patient. CONCLUSION: It's important to reconstruct elbow joint support structure and function after resection of such a large malignant tumor in young patients. We used 3D printed implant to maintain a functional limb and it was an excellent alternative treatment.

Alveolar Osteitis: Patient's Compliance with Post-extraction Instructions Following Permanent Teeth Extraction.

AIM: The study aims to evaluate the patients' compliance with post-extraction instructions to prevent the development of alveolar osteitis and keep the health of the socket. Alveolar osteitis "Dry socket" is considered one of the most common complications after extraction. MATERIALS AND METHODS: Study was based on an observational cross-sectional design involving 201 subjects (individuals). The subjects were evaluated via a survey questionnaire and clinical examination after obtaining their verbal and written consent. The study questionnaire was divided into the following sections; section one records the demographic data about the subject while the second section focuses on self-assessment mainly regarding compliance with post-extraction instructions and pain. RESULTS: A total number of patients included in the study was 201, 122 (60.7%) male and 79 (39.3%) female with an age of more than 18 years. No statistically significant association was reported between a medical condition and dry socket. Out of 201 patients came for clinical examination, 89 felt pain at the site of extraction at different period started from the day of extraction till the day of examination with various pain intensity. Females were the most to feel pain after tooth extraction with 78%. Regarding prevalence, 14 (7%) patients reported having dry socket and poor socket status. A statistically significant association of non-complying patients with the incidence of the dry socket was observed for a wide range of age (18 to 40 years) Conclusion: The study showed a high degree of association between the incidence of dry socket cases for patients with poor compliance with post-extraction instruction. A strong relation was observed between the patients who felt pain and their gender (females) Clinical significance: Based on the findings of the present study, we recommend the need to properly educate patients on the effect of compliance and the various complications and factors affecting the socket status after tooth extraction due to non-compliance.
