Charcot arthropathy is a rapidly progressive and destructive form of arthropathy caused by various neurological diseases. Total hip arthroplasty (THA) is usually contraindicated in patients with Charcot arthropathy; however, recent studies have reported good results following THA in this patient population. Herein, we report a case of Charcot arthropathy secondary to syphilis in a patient who was successfully treated with constrained THA, a new type of THA. A 56-year-old man was injured in a car accident, and a displaced acetabular fracture was revealed three weeks later. He was treated conservatively but soon developed greater displacement of the fracture and femoral head destruction. The patient was referred to our hospital for further treatment. The patient had pelvic pseudarthrosis secondary to Charcot arthropathy at the time of the first visit to our hospital. First, THA was performed with the acetabular reconstruction of the deficient bone. However, the acetabular implant was displaced one week postoperatively. THA revision was performed using a constrained cup. Postoperatively, the patient exhibited good hip stability without dislocation. However, displacement of the acetabular cup occurred one year after the second surgery. We performed a re-revision of THA using a new type of constrained cup that offers a high level of constraint to maintain range of motion (ROM) and prevent dislocations. The patient was able to walk with a T-cane one year postoperatively. Herein, we report a difficult case of revision THA in a patient with Charcot arthropathy concomitant with syphilis. THA is usually contraindicated in patients with Charcot arthropathy; however, we propose that THA using constrained cups that offer a wider ROM may be a useful therapeutic strategy for the treatment of Charcot arthropathy.

A spinal cord injury is now the most common cause of Charcot Spinal Arthropathy (CSA). Paraplegia, loss of pain sensation, laminectomies, and spinal fusions involving more than 5 levels are all risk factors for developing this condition. Low back pain and spinal abnormalities are common symptoms. Circumferential arthrodesis is the chosen treatment. Implant failure and new-onset CSA, which necessitates re-instrumentation, are some of the risks associated with this treatment. This is the case of a patient with a post-traumatic spinal cord injury presenting with spinal Charcot disease with a very long follow-up. We report a unique complication with the replacement of the discal space and portions of the vertebral bodies by fibrotic tissue with an extraordinary spinal movement in the coronal and sagittal planes. Recurrent Charcot disease at the same level or at a caudal level is a devastating complication in spinal surgery. Since this disease naturally exposes the patient to iterative surgeries, it would be wise to limit the extent of the arthrodesis to an optimal number of levels sufficient to ensure perfect stability of the construct and not to be very extensive from the first surge. The risk would increase the fused levels which limit the availability of mobile buffer levels and increase the stress on the remaining levels. Regular follow-ups to the patient should be done to detect recurrence at the same site or distal to the instrumentation.

Charcot spinal arthropathy is a progressively degenerative joint disorder of the vertebrae. Historically, it was a common consequence of tertiary syphilis. Currently, it is a rare complication of spinal cord injury (SCI). We present the case of a 28-year-old patient with paraplegia who developed progressive, neurogenic bowel dysfunction due to Charcot spinal arthropathy. Our patient had upper motor neuron bowel syndrome secondary to SCI which advanced to lower motor neuron bowel syndrome. Charcot spinal arthropathy should be considered as a possible cause for symptom progression in SCI patients. This case illustrates the connection between Charcot spine and lower motor neuron dysfunction in the setting of prior upper motor neuron dysfunction.

BACKGROUND: Charcot spinal arthropathy, also known as Charcot spine and neuropathic spinal arthropathy, is a progressive and destructive condition that affects an intervertebral disc and the adjacent vertebral bodies following loss of spinal joint innervation. We report the first case of Charcot spinal arthropathy (CSA) associated with cerebrospinal fluid (CSF)-cutaneous fistula.
METHODS: A 54-year-old male who underwent T10-L2 posterior instrumented spinal fusion seven years prior for treatment of T11 burst fracture and accompanying T11 complete paraplegia visited our department complaining of leakage of clear fluid at his lower back. The patient had also undergone various types of skin graft and myocutaneous flap surgeries for treatment of repetitive pressure sores around his lumbosacral area. The patient presented with persistent CSF leakage from a cutaneous fistula (CSF-cutaneous fistula) formed in a lumbosacral pressure sore. The CSF-cutaneous fistula arose from the L5 post-traumatic CSA. Surgery was planned for management of CSF-cutaneous fistula and post-traumatic L5 CSA. We successfully treated the CSF-cutaneous fistula with ligation and transection of the dural sac and cauda equina at the L2-L3 level. In addition, the post-traumatic L5 CSA was successfully treated with a posterior four-rod spinopelvic fixation from T9 to ilium and S2 foramina. After surgery, the CSF leakage stopped and no other adverse neurological changes were found. The four-rod spinopelvic construct was well maintained five years later.
CONCLUSIONS: CSA associated with CSF-cutaneous fistula is a very rare disorder. Only surgical treatment for both CSA and CSF-cutaneous fistula with ligation and transection of the dural sac and posterior four-rod spinopelvic fixation can bring satisfactory results.

Charcot spinal arthropathy (CSA) is a rare spinal disorder presenting neuropathic osteoarthropathy of facet joints leading to progressive destruction. After L4-5 PLIF, a 63-year-old woman with Parkinson\'s disease (PD) underwent L3-4 and L5-S1 PLIF for primary adjacent segment disease caused by degenerative change, which was found as facet joint osteophytes and a vacuum disc phenomenon with endplate sclerosis. However, her postural disorder from PD deteriorated, and strong opioid analgesics were administered for severe recurring low back pain. Anterior subluxation at L2-3 occurred because of destructive secondary adjacent segment disease, which was found as destruction of the endplate and the facet without degenerative change, and formation of paravertebral osteophytes and fluid collection in the intervertebral space. The appearance on imaging met that for neuroarthropathic change, which was previously reported as CSA. L2-3 PLIF following extension of posterior fusion to T10 was additionally performed, and the postoperative course was uneventful with symptomatic improvement. In this case, the important finding was in the different appearance of the disease between adjacent segments on imaging. It is possible that deterioration of PD and administration of the analgesics inhibited deep pain sensation, and concentration of mechanical stress in the proximal adjacent segment by the long lever arm because of extension of the fusion level resulted in neuroarthropathic change of the facets in the secondary adjacent segments. The pathophysiology of association of CSA and PD remains unknown. However, we recommend vigilance for destructive neuroarthropathic facet change as CSA after spinal surgery in patients with severe PD.

Charcot spinal arthropathy (CSA) is a rare progressive disorder of vertebral joint degeneration that occurs in the setting of any condition characterized by decreased afferent innervation with loss of deep pain and proprioceptive sensation in the vertebral column. While surgical circumferential arthrodesis remains the most effective treatment modality, it is associated with multiple complications, including hardware construct failure. This manuscript represents an up-to-date narrative review of the treatment of CSA, its associated complications, and complication prevention.

BACKGROUND: Charcot spine arthropathy (posttraumatic neuroarthropathy of the spine) has been reported to be a very late and rare complication of spinal cord injury. Charcot of the cervicothoracic and upper thoracic region rarely is reported in the literature. Charcot spinal arthropathy is a cause of progressive deformity and may present as late as 30 years after the original spinal cord injury. This is more common in paraplegic patients who are actively ambulating.
METHODS: A 56-year-old patient with complete paraplegia for approximately 20 years after spinal cord injury presented with severe kyphous deformity and instability of thoracolumbar spine. His sensory level to deep pain was at thoracic (D4). He kept developing new neuroarthropathies at different segments within a span of 5-6 months after every decompression and fusion with anterior cage and posterior instrumentation done. A total of 3 surgeries had been done in span of 2 years, initially thoracic, then lumbar and finally cervicothoracic junction.
CONCLUSIONS: We present this case because of the challenges in surgery for instrumentation of new Charcot spinal arthropathy. Reports of neuroarthropathy developing above the level of spinal cord injury and at the cervicothoracic junction are rare. The treating surgeon should be cognizant of the possibility of developing secondary levels of neuroarthropathy above and below a previously successful fusion.

OBJECTIVE: To investigate the occurrence of Charcot spinal arthropathy (CSA) after sacral deafferentation (SDAF) and sacral anterior root stimulation (SARS) of the bladder in patients suffering from neurogenic lower urinary tract dysfunction (NLUTD) as a result of spinal cord injury (SCI).
METHODS: Retrospective evaluation of patients who had undergone SDAF/SARS at a single SCI rehabilitation centre. The occurrence rate of stimulation dysfunction was determined, and the medical records and radiological images of the included patients were examined for CSA. The diagnosis of CSA was based on radiological criteria. The occurrence rate of CSA was estimated for all SARS patients and for those with SARS dysfunction, and the odds ratios (OR) for the occurrence of CSA were calculated.
RESULTS: In 11/130 SARS patients (8%), CSA was observed a median 8 years (95% CI 5-16 years) after SDAF/SARS or a median 21 years (95% CI 9-41 years) after SCI had occurred. The median follow-up time was 14 years (range 6-25 years). The proportion of patients with CSA was significantly (P = 0.036) greater in patients with SARS dysfunction (7/41) than in patients without SARS dysfunction (4/89). The odds of CSA were four times greater (OR 4.3, 95% CI 1.0-21.5) in patients with SARS dysfunction compared to those without. Furthermore, the odds of CSA were 20 times greater (OR 20.2, 95% CI 8.4-47.0) in patients with SARS compared to those without.
CONCLUSIONS: Charcot spinal arthropathy should be considered a potential long-term complication of SDAF/SARS, and spinal instability is a possible reason for SARS dysfunction.

BACKGROUND: Neuropathic (Charcot) spinal arthropathy (CSA) is a rare but progressive and severe degenerative disease that develops in the absence of deep sensation, for example, after spinal cord injury. The diagnosis of CSA is often delayed as a result of the late onset or slow progression of the disease and the nonspecific nature of the reported clinical signs. Considering risk factors of CSA in combination with the common clinical signs may facilitate timely diagnosis and prevent severe presentation of the disease. However, there is a lack of data concerning the early signs and risk factors of CSA. Furthermore, the complications and outcomes after surgical treatment are documented insufficiently.
OBJECTIVE: To investigate the early signs and risk factors of CSA after spinal cord injury, as well as the complications and outcome after surgical treatment.
METHODS: Retrospective case series from a single center.
METHODS: Twenty-eight patients with 39 Charcot joints of the spine.
METHODS: Clinical signs, radiological signs, risk factors, and complications.
METHODS: The case histories and radiological images of patients suffering from CSA were investigated.
RESULTS: The first clinical symptoms included spinal deformity, sitting imbalance, and localized back pain. Long-segment stabilization, laminectomy, scoliosis, and excessive loading of the spine were identified as risk factors for the development of the disease. Postoperative complications included implant loosening, wound healing disturbance, and development of additional Charcot joints. All patients were able to return to their previous levels of activities.
CONCLUSIONS: Radiological follow-up of the entire thoracic and lumbar spine should be performed in paraplegic patients. Risk factors in combination with typical symptoms should be considered to facilitate early detection. Functional restoration can be achieved with appropriate surgical techniques.
