Purpose: To highlight the importance of preventing visceral injury due to prominent anterior implants at the spinal column.

Methods: A 52-year-old man with cord compression was treated with a T9/10 discectomy and instrumented fusion via a right thoracotomy and trans-pleural approach. Postoperatively, he had improved lower limb numbness. However, after a bout of coughing, there was sudden increase in chest drain output, hemodynamic instability and massive fluid collection in the right chest cavity.

Results: Emergency re-exploration of the thoracotomy was performed and a 6 cm laceration of the right postero-medial diaphragm was identified as the bleeding source and was found to be in close proximity with the locking nut of the anterior implants. The laceration was repaired and a soft synthetic patch was used to cover the implants. Postoperatively, the hemothorax resolved and the patient recovered from the neurological deficit.

Conclusions: Prevention of diaphragmatic injury can be performed using lower profile and less sharp-edged implants. Implant coverage with a soft synthetic material is necessary if unable to perform direct repair of the parietal pleura over the implants.

Background: There is no consensus on the association between final local kyphosis and residual back pain (RBP) after traumatic vertebral fracture. The aim of this study was to investigate whether there is an association between the final local kyphosis angle and RBP in patients with traumatic vertebral fractures at the thoracolumbar junction who underwent single posterior surgery with percutaneous pedicle screws and implant removal after fracture healing. A second goal was to determine the optimal cut-off value for the final local kyphosis angle with and without RBP.

Background: The objective of this report is to present a case of two cervical spine artificial discs (Bryan Cervical Disk) that completely disappeared within 6 months as a result of a high-energy trauma more than 10 years after the initial surgery. Implant dislocation is a known complication in artificial cervical disc replacement. However, this report presents the case of an exceptional migration path with esophageal ingrowth and rectal excretion, not only for one artificial disc but for two at different times It highlights the need for long-term follow-up examinations after artificial cervical disc arthroplasty (ACDA).

Burn injuries in patients with significant pre-existing medical conditions provide unique challenges in both medical management and surgical planning. Spasticity, if left untreated, can be one of the most disabling consequences of a neurologic injury. Treatment is largely dependent on pharmacologic management with anti-spasmodic agents such as baclofen.

Introduction: Cataract is a leading cause of visual impairment globally and in Malaysia, with surgery being the definitive treatment. While intracapsular cataract extraction (ICCE) is now less commonly performed due to advancements in surgical techniques, it remains essential in specific cases, such as those with weak zonular support. This study aims to evaluate the incidence, clinical profiles, and visual outcomes of patients who underwent ICCE, with or without intraocular lens (IOL) implantation, at Hospital Melaka, Malaysia, over the past decade.
