Microsurgical Repair of Severed Thoracic Spinal Cord and Clinical Outcome: Technical Case Report

This report describes a case of successful repair of severed thoracic spine in a young man who presented with a penetrating stab injury to spine resulting in Brown-Séquard syndrome. Surgical technique and post-operative management is discussed.A 34-year-old fit and well healthy man was admitted with a history of stab injury to the thoracic spine at thoracic T2/3 level with ASIA impairment score (AIS) score D with an incomplete spinal cord affecting his left lower limb with complete paralysis and right lower limb paresis with impaired sensation below T6 level to L5. Neuroimaging confirmed a penetrating knife injury traversing the T2/3 level causing hemi-section of the spinal cord confirmed intraoperatively. He underwent an urgent exploratory surgery of his spine and a T2/3 laminectomy was performed to aid removal of the knife. The dura was noted to be contused and severed spinal cord was noted to be severed with associated cord oedema. A microsurgical repair of the severed cord was performed with duroplasty followed by intense neuro-rehabilitation. On a three month follow up his AIS score is E with lower limb power is 5/5 bilaterally and he is able to mobilise independently up to 8-10 steps without any supportive aid and with crutches he is independently functional and mobile.This is the first documented case of microsurgical repair of severed thoracic spinal cord secondary to traumatic knife injury. In the management of such scenario, apart from the removal of foreign body, repair of the cord with duroplasty should be carefully considered. The role of spinal neuroplasticity in healing following timely repair of the spinal cord along with intense rehabilitation remains the key. This had resulted in a good clinical and functional outcome with in a 12 month period.

Subcutaneous Transposition of the Flexor Pollicis Longus: Does It Provide Increased Length for Tendon Repair? A Cadaveric Study

Background: Flexor pollicis longus (FPL) tendon lacerations typically occur via sharp mechanisms such as knife injury. When the injury is chronic, it may be difficult to perform a tension free repair, and tendon lengthening may be required. This article proposes a technique that transposes the proximal tendon stump over the thenar eminence subcutaneously, out of the carpal tunnel, in an attempt to gain additional tendon length by eliminating the sharp turn the FPL takes. Methods: A total of 17 cadaveric hands were used. The FPL tendon was identified and affixed to soft tissue in the distal forearm as well as at the thumb metacarpophalangeal (MP) joint with hypodermic needles. The tendon was then transected at the level of the MP joint of the thumb, removed from the carpal tunnel, and transposed on top of the thenar eminence to reach where it had been transected. The length gained by transposing the tendon was recorded by measuring the overlap of the tendon ends at the MP joint. Results: The mean amount lengthened was 7.6 mm with a standard deviation of 2.4 mm, ranging from as little as 5 mm to as high as 13 mm. Conclusions: To our knowledge, transposition of FPL tendon is a novel technique that has not been reported. Based on our cadaveric study, it can be used to bridge gaps between approximately 5 mm and 10 mm. Clinically, this amount of gap could potentially be more easily managed by simply making the repair tighter than usual as opposed to transposing the tendon.

A CASE OF DIAGNOSTIC OF THE TRAUMATIC DIAPHRAGMATIC HERNIA DESGUISED AS PLEURISY

The article presents the literary overview dedicated to the diaphragmatic hernias. As an example, a case of the traumatic diaphragmatic hernia with the clinical picture of the pleurisy was described. The thoracoabdominal knife injury of the diaphragm was the feasible reason of this hernia. In this case, a long asymptomatic course of the disease with some gastroenterological symptoms was the reason for the early diagnostics not to be performed. Firstly, the patient was hospitalized to the pulmonology department because of the pleurisy-like clinical picture of his case. A diaphragmatic hernia was found only after examination of the patient. A laparoscopic operation failed and the patient was successfully treated by the surgery.

Management Considerations for a Retained Plantar Knife Injury

A 13-year-old girl presented to the emergency department in stable condition with a retained penetrating knife wound injury in her right foot. Routine radiographs taken of the foot revealed deep tissue penetration by the knife without frank bony involvement. It was decided to remove the object in the operating room. Simple removal was performed, followed by wound exploration. The patient was admitted to the hospital for one night of observation and then was discharged without further complications.

Penetrating knife injury to the skull: A case report in pediatric neurosurgical care

Isolated penetrating head injury in children is rare and is usually accidental. Each case is unique since the penetrating object and the trajectory through the brain parenchyma vary greatly among patients. We present a three-year-old girl who presented with a kitchen utility knife penetrating her left midface, skull, and brain abutting the anterior cerebral vasculature. Though the patient initially presented to a local trauma center, there were no pediatric nor vascular neurosurgeons on staff. Thus, she was transferred to our tertiary facility for definitive surgical management. A pediatric and vascular neurosurgeon worked together to remove the knife safely and the underlying vasculature remained intact. Postoperatively, the patient did well and was neurologically intact. Though penetrating cranial injury is rare in the pediatric population, such complex cases of brain injury can be properly managed with good outcome by an interdisciplinary team of specialists in tertiary care centers and can result in an excellent surgical and functional outcome for the patient.
