Spinal Cord Injury With Tetraplegia in Young Persons After Diving Into Shallow Water: What Has Changed in the Past 10 to 15 Years?

Bilateral Cervical Facet Dislocation Due to Catastrophic Shallow Water Diving: A Case Report

Bilateral cervical facet dislocation is a rare injury resulting from headfirst shallow water diving accidents. Accurate diagnosis, prompt management, precise intervention, and aggressive rehabilitation can lead to a favourable neurologic and functional outcome for cervical spine injuries. In this case, we present a young adolescent patient who experienced bilateral facet dislocation of C4/C5, resulting in incomplete central cord syndrome neurological deficits (American Spinal Injury Association (ASIA) Impairment Scale C) due to a dangerous shallow water diving accident. The patient subsequently underwent emergency posterior instrumentation and decompression for stabilization and rehabilitation. Immediately following the surgery, he exhibited substantial neurologic recovery and was able to walk independently after six months. This case is unique not only for its rarity but also because it involved a young adolescent, highlighting the need for increased awareness and preventive measures to reduce the risk of dangerous shallow water diving accidents.

Demographics and functional outcome of shallow water diving spinal injuries in northern Germany - A retrospective analysis of 160 consecutive cases

AIM

To describe demographic findings, typical injuries and functional neurological outcomes in patients with cervical trauma and tetraplegia sustained after diving into shallow water.

PATIENTS AND METHODS

A retrospective study was performed including all patients treated in BG Klinikum Hamburg suffering from tetraplegia after jumping into shallow water between 1st June 1980 and 31st July 2018.

RESULTS

One hundred and sixty patients with cervical spinal injuries and tetraplegia following a dive into shallow water were evaluated. Of these, 156 patients (97.5%) were male. The mean age was 24.3 years ± 8.1 and the accidents occurred most often in inland waters (56.2%) and mostly between May and August (90.6%). In all cases there was one vertebra fractured, whereas in 48.1% of cases, two vertebrae were severed. In the majority of cases (n = 146), a surgical procedure was performed. Overall, the mean hospital stay was 202 days (±72, range: 31-403) and one patient died. On admission, 106 patients (66.2%) showed a complete lesion according to AIS A, with incomplete lesions in the remaining 54 patients (AIS B: n = 25 [15.6%], AIS C: n = 26 [16.3%], AIS D: n = 3 [1.9%]). In two thirds of the patients, the level of paralysis on admission was at the level of segments C4 (31.9%) or C5 (33.7%). Seventeen patients (10.6%) needed prehospital resuscitation. In 55 patients (34.4%), the neurological findings improved during the course of inpatient treatment and rehabilitation. Sixty-eight patients (42.5%) developed pneumonia, of which 52 patients (76.5%) were ventilated. In addition, 56.5% of patients with paralysis levels C0-C3 required ventilation, whereas only 6.3% of patients with paralysis levels C6-C7 were affected. Three patients (1.9%) were discharged from hospital with continuous ventilation. Overall, 27.4% of all AIS A patients, 56% of all AIS B patients and 46.2% of all AIS C patients improved neurologically, with 17% of all patients being able to walk.

CONCLUSIONS

The consequences of a cervical spine injury after diving into shallow water are severe and lifelong. Functionally, patients may benefit from care in a specialised centre, both in the acute phase and during rehabilitation. The more incomplete the primary paralysis, the greater the possibility of neurological recovery.

Spinal Fractures during Touristic Motorboat Sea Cruises: An Underestimated and Avoidable Phenomenon

PURPOSE

Each summer, many vacationers enjoy the Mediterranean Sea shores. Among the recreational nautical activities, motorboat cruise is a popular choice that leads to a significant number of thoracolumbar spine fractures at our clinic. This phenomenon seems to be underreported, and its injury mechanism remains unclear. Here, we aim to describe the fracture pattern and propose a possible mechanism of injury.

METHODS

We retrospectively reviewed the clinical, radiological, and contextual parameters of all motorboat-related spinal fracture cases during a 14-year period (2006-2020) in three French neurosurgical level I centers bordering the Mediterranean Sea. Fractures were classified according to the AOSpine thoracolumbar classification system.

RESULTS

A total of 79 patients presented 90 fractures altogether. Women presented more commonly than men (61/18). Most of the lesions occurred at the thoracolumbar transition region between T10 and L2 (88.9% of the levels fractured). Compression A type fractures were seen in all cases (100%). Only one case of posterior spinal element injury was observed. The occurrence of neurological deficit was rare (7.6%). The most commonly encountered context was a patient sitting at the boat's bow, without anticipating the trauma, when the ship's bow suddenly elevated while crossing another wave, resulting in a "deck-slap" mechanism hitting and propelling the patient in the air.

CONCLUSIONS

Thoracolumbar compression fractures are a frequent finding in nautical tourism. Passengers seated at the boat's bow are the typical victims. Some specific biomechanical patterns are involved with the boat's deck suddenly elevating across the waves. More data with biomechanical studies are necessary to understand the phenomenon. Prevention and safety recommendations should be given before motorboat use to fight against these avoidable fractures.

An Overview of Spinal Injuries due to Dive or Fall into Shallow Water: Our Long-Term, Double-Center Experience from the Aegean Coast

Purpose

We aimed to evaluate the demographic and clinical features of patients with cervical spinal injuries secondary to shallow-water diving and share our therapeutic outcomes.

Methods

A retrospective study was carried out using data extracted from the medical files of 39 patients (3 females and 36 males) who were treated surgically (n = 29) or conservatively (n = 10). Demographics, clinical features, operative data, American Spine Injury Association (ASIA) impairment scales, and Karnofsky Performance Status (KPS) results were noted.

Results

The average age of our series (n = 39) was 31.59 ± 14.80 (range, 14 to 92) years. The vast majority of patients (n = 34, 87.2%) presented with isolated cervical trauma. At initial admission, neurological deficits were diagnosed in 22 (56.4%) patients. A single-level cervical involvement was noted in 18 (46.2%) patients, while 21 cases (53.8%) displayed injury involving multiple levels. The levels of cervical injury were C5 (n = 16, 41%), C6 (n = 11, 28.2%), C7 (n = 6, 15.4%), C1 (n = 5, 12.8%), and C4 (n = 1, 2.6%). A total of 22 patients had neurological deficits at admission. Surgery was performed using anterior (n = 21, 72.4%), posterior (n = 7, 24.1%), and combined anterior and posterior (n = 1, 3.4%) routes. Nine patients (23.1%) exhibited improvement in their neurological deficits. There were significant improvements in both the ASIA impairment scale and KPS results after treatment.

Conclusion

Our data indicated that dive- or fall-related cervical spinal injuries are associated with profound morbidity. Reinforcement of primary prevention, identification of target population, and increased awareness on this topic are the key steps to minimize the frequency and severity of complications and to optimize therapeutic outcomes.
