AI Article Synopsis
- The study explored the safety and effectiveness of cervical pedicle screw fixation for patients with cervical spine fracture-dislocation, traditionally seen as risky due to proximity to neurovascular structures.
- Involving 48 patients with various degrees of spinal cord injury, results showed that all achieved solid bony fusion and stable fixation within six months; many improved in their ASIA impairment classification.
- The research concluded that cervical pedicle screw fixation is a reliable technique for cervical stability restoration, highlighting the importance of careful pre-operative imaging and precise screw placement.
Article Abstract
Introduction: Usually, cervical pedicle screw fixation has been considered too risky for neurovascular structures. The purpose of this study was to investigate the method and efficacy of the cervical pedicle screw system for fracture-dislocation of the cervical spine because of its rigid fixation.
Patients And Methods: A prospective study was conducted involving 48 patients with cervical spine fracture-dislocation who underwent cervical pedicle screw fixation surgery between January 2003 and January 2007. All patients had various degrees of cord injury, and they were classified according to the American Spinal Cord Injury Association (ASIA) Impairment Scale: 18 cases were grade A, 15 grade B, 10 grade C, and 5 grade D.
Results: Six months after the operation, all patients had achieved solid bony fusion and stable fixation of the related segments. Thirty patients with incomplete spinal cord injury improved their ASIA Impairment Scale classification by 1 to 2 grades after the operation. Eighteen patients with complete spinal cord injury had no improvement in neural function. However, nerve root symptoms such as pain and numbness were alleviated to some extent.
Conclusions: The cervical pedicle screw system is an effective and reliable method for the restoration of cervical stability. Sufficient pre-operative imaging studies of the pedicles and strict screw insertion technique should be emphasised.

Anatomical study of the vascularization of the pedicled osteo-myo-cutaneous scapulo-dorsal flap.

Maxillo-Facial Surgery Department, Beaujon University Hospital, Clichy, France.
Purpose: The main objective of this study was to conduct a radioanatomical study of the osteo-myo-cutaneous scapulo-dorsal pedicled flap.
Methods: A radiological study was performed to study the anatomical variations of the dorsal scapular pedicle (origin, course of the deep branch of the dorsal scapular artery (DSA) in relation to the medial border of the scapula, perforators from the superficial branch of the DSA). Perforators from the superficial branch of the DSA were also identified on anatomical subjects, and their cutaneous vascular territory was determined.
Pedicle ossification following mandibular reconstruction using fibular free flap in a patient with osteoradionecrosis of the jaw: a case report.

Article Synopsis
- Pedicle ossification is a rare complication that can occur after using a fibular free flap (FFF) for mandibular reconstruction, potentially simulating tumor recurrence and leading to diagnostic challenges.
- A case study of a 38-year-old male with squamous cell carcinoma highlighted how postoperative complications led to the need for FFF reconstruction, and over 4 years, CT scans showed ossification in the flap's vascular pedicle, yet the patient remained asymptomatic.
- Regular imaging and clinical assessments are key to distinguishing ossification from tumor recurrence, with surgery usually only considered if symptoms arise.
The pectoralis major myocutaneous pedicled flap-Its past and current practice in a dedicated microsurgery service. Review of the literature, and debunking controversies.

Background: The pectoralis major myocutaneous pedicled (PMMP) flap is still considered by many a workhorse flap in head and neck (H&N) reconstruction, despite free flap surgery advancing. The authors aimed to examine this claim and associated myths and controversies by analyzing literature trends and revealing the role of the PMMP flap in a well-established microsurgery center.
Methods: The senior author's reconstructive H&N practice between 1995 and 2022 was reviewed to describe and critically judge primary and secondary PMMP flap decisions to provide invaluable lessons learned and debunk common controversies related to complex H&N reconstruction.

Objectives: To address controversies regarding target volume delineation for adjuvant intensity-modulated radiation therapy for oral cavity squamous cell carcinoma with pedicled flap reconstruction and elective nodal irradiation (ENI).
Materials And Methods: During target volume delineation, the primary tumor bed was the pre-surgical gross tumor volume with an additional isotropic margin of 5-10 mm. Additionally, the flap and body tissue junction were given a margin of 5-10 mm (if not already given).

Objective: This retrospective cohort study aims to compare donor site morbidity of three commonly used upper extremity flaps used in head and neck reconstructive surgery: scapular tip free flap (STFF), radial forearm free flap (RFFF), and pectoralis major pedicled flap (PMPF).
Methods: The billing database of an urban, academic, tertiary otolaryngology practice was queried to identify patients who underwent STFF, RFFF, and PMPF from 2020 to 2023. The primary outcome was identification of donor site pain and need for physical therapy (PT) referral after undergoing reconstruction.
