BACKGROUND: Patients with extraspinal diffuse idiopathic skeletal hyperostosis (DISH) involving the hip joint have symptoms like femoroacetabular impingement (FAI). To date, no reported study has determined the clinical outcomes of arthroscopic treatment in extraspinal DISH involving the hip joint. METHODS: A total of 421 hips with FAI that underwent arthroscopic treatment were reviewed retrospectively. We determined the extraspinal involvement of DISH with three-dimensional computed tomography (3D-CT) and simple radiography of the pelvis and hip joint. Clinical outcomes were evaluated at a minimum of 2 years postoperatively. The visual analog scale score (VAS), modified Harris hip score (MHHS), and hip outcome score–activity of daily living scale (HOS-ADL) were used, and hip range of motion (ROM) was evaluated pre- and postoperatively and at the time of the final follow-up. RESULTS: Among the 421 hips (372 patients) with FAI that underwent arthroscopic treatment, 17 hips (12 patients, 4.04%) had extraspinal DISH on the hip joints. The mean age of the patients was 51.5 years. The 3D-CT scans and simple radiographs showed extraspinal DISH on multiple points around the pelvis and hip joint. Nine of the 17 hips (seven of 12 patients) had spinal DISH. At the final follow-up, VAS, MHHS, and HOS-ADL improved significantly from 6.5, 65.3, and 66.6, respectively, to 1.2, 87.8, and 89.5, respectively, and hip flexion and internal rotation improved significantly from 97.7° and 7.9°, respectively, to 117.1° and 18.2°, respectively. CONCLUSIONS: This study has demonstrated that extraspinal DISH involving the hip joint could lead to FAI, and arthroscopic treatment could result in relief of symptoms, including pain and ROM limitation, in extraspinal DISH patients.

BACKGROUND: Diffuse idiopathic skeletal hyperostosis (DISH) is characterized by ossification of the enthesis. The diagnosis has been mainly based on the chest or whole spine lateral plain film. Recently, chest or thoracolumbar computed tomography (CT) has been reported to be more reliable for the diagnosis of DISH. The purposes of this study were to investigate the prevalence and location of DISH and evaluate the prevalence of comorbidities, such as ossification of the posterior longitudinal ligament (OPLL) and ossification of the ligamentum flavum (OLF), using whole spine CT. METHODS: Whole spine CT scans of patients over 16 years of age who were examined at Cheju Halla General Hospital between February 2011 and December 2016 were reviewed for this study. The diagnosis of DISH was made according to the modified Resnick criteria. The prevalence of DISH in each age decade and its location were evaluated. Also, the prevalence of OPLL and OLF in DISH patients was investigated. RESULTS: The overall incidence of DISH was 24.4% (40 of 164 cases). There was no case of DISH in patients in their 40s and younger. The percentile incidences of DISH in patients in their fifth, sixth, seventh, eighth, and ninth decades were 20.0% (4 of 20 cases), 32.3% (10 of 31 cases), 40.0% (10 of 25 cases), 34.5% (10 of 29 cases), and 27.3% (6 of 22 cases), respectively. A strong positive correlation between the age decade and the incidence of DISH was noted (r = 0.853, p = 0.007). DISH patients had higher incidences of OLF (22.5%) and OPLL (37.5%). The most common location of DISH was the middle thoracic spine (90.0%) followed by the lower thoracic spine (87.5%). There was one case of DISH involving only the cervical spine. CONCLUSIONS: The incidence of DISH diagnosed by CT was higher than we expected. Whole spine CT can be a valuable modality to evaluate the location of DISH in the cervical and lumbar spine and the comorbidity rates of OLF and OPLL.

Degenerative disease of the spine affects all people and several distinct degenerative processes can be observed. These processes are associated with characteristic radiographic and pathologic abnormalities. Intervertebral osteochondrosis, spondylosis deformans, osteoarthritis of the facet joint, and diffuse idiopathic skeletal hyperostosis (DISH) are the major forms of degenerative diseases in lumbar spine. Ultrasound is frequently used to guide several lumbar procedures before and after operation, or just for nerve block and intra-articular injection even though fluoroscopy have been used preferentially in interventional procedures due to well visualization of the needle and of the spreading of the injections. However, more and more clinicians have applied ultrasound-guided intervention with several advantages, such as no radiation exposure, relatively inexpensive in cost, and smaller space in occupancy. We reviewed sonoanatomy and well established several ultrasound-guided interventions in lumbar spine, such as medial branch block, facet joint injection, caudal block, and lumbar epidural block.

Diffuse idiopathic skeletal hyperostosis (DISH) is characterized by calcification of different entheseal sites including the anterior longitudinal ligament of the spine. There is no documented information about DISH in Oman. This study determined the prevalence of DISH and associated factors among elderly subjects in a national tertiary care referral hospital in Oman. This retrospective study reviewed chest X-rays of all patients aged more than 50 years, referred to the radiology department of Sultan Qaboos University Hospital in the year 2016, based on the Resnick's criteria. The prevalence was expressed as proportions across age groups and sex. Chi-square test and logistic regression analysis was done to determine the association of the age and sex with DISH. A total of 1305 chest X-rays of patients were reviewed. The overall prevalence of DISH was 10%, with male to female ratio of 1.56:1. The odds ratio for males and increasing age were 1.63 (95% confidence interval [CI], 1.12–2.3; P<0.05) and 1.34 (95% CI, 1.14–1.58; P<0.001) respectively. The prevalence increased with age to maximum of 13% in the age group of ≤80. The pre-stage DISH prevalence was 9.3% and more frequently observed among males. Prevalence of DISH in the national tertiary care referral center in Oman is lower than in Jewish population, almost similar to Japanese, but higher than in Koreans. DISH prevalence is positively associated with age and sex. It is necessary to take appropriate precautionary measures to target the ageing population in Oman, especially elderly males.

STUDY DESIGN: Retrospective cohort study. PURPOSE: The purpose of this study was to evaluate the prevalence of diffuse idiopathic skeletal hyperostosis (DISH) in patients with spinal diseases determined by roentgen images of the whole spine. OVERVIEW OF LITERATURE: Although several studies have investigated the prevalence of DISH in healthy subjects, no detailed data have been reported on the prevalence of DISH in patients with degenerative spinal disorders. METHODS: Standing whole-spine roentgen images of 345 consecutive patients who underwent surgery in our hospital were obtained. Patients aged <18 years or with congenital spinal disease, metastatic spinal tumors, or inflammatory spinal disease were excluded. In total, 281 patients were eligible for inclusion. The presence of DISH was assessed according to Resnick's criteria and Mata's scoring system. The prevalence, location, and numbers of fused vertebral bodies of DISH were recorded. RESULTS: DISH was present in 25.6% of patients (72/281). The prevalence of DISH in the 41–49, 50–59, 60–69, 70–79, and ≥80 year age groups was 8.3% (2/24), 9.8% (5/51), 16.0% (12/75), 49.5% (48/97), and 33.3% (4/12), respectively; the prevalence increased with age. The average number of fused vertebral bodies was 7.5. More than 80% of DISH was located from T7 to T11, and more than 95% of DISH was located at T9/10. Patients with DISH were significantly older (71.1 years vs. 60.9 years, p<0.05), and men were more likely to have DISH than women (p<0.05). CONCLUSIONS: In patients with degenerative spinal diseases with DISH, fused vertebrae were found most frequently in the lower thoracic spine, and their prevalence increased with age. DISH may be an age-related skeletal disorder with a higher overall prevalence in patients with spinal disorders than that in healthy subjects.

STUDY DESIGN: Case report. OBJECTIVES: To report a case of progressive kyphotic deformity after spinal fusion in a patient with diffuse idiopathic skeletal hyperostosis (DISH). SUMMARY OF LITERATURE REVIEW: DISH is characterized by spinal and peripheral enthesopathy, and is a completely different disease from ankylosing spondylitis (AS). Though DISH can be associated with thoracic kyphosis, no reports have described a progressive thoracolumbar kyphotic deformity after spinal fusion surgery in a DISH patient. MATERIALS AND METHODS: A 47-year-old male presented with pain in the thoracolumbar region. After excluding the possibility of AS and confirming the diagnosis of DISH, we performed spinal fusion for the treatment of a T11-T12 flexion-distraction injury. The kyphotic deformity was found to be aggravated after the first operation, and we then performed corrective osteotomy and additional spinal fusion. Results: The kyphotic deformity of the patient was corrected after the second operation. RESULTS: The kyphotic deformity of the patient was corrected after the second operation. CONCLUSIONS: In DISH patients in whom AS must be excluded in the differential diagnosis, a kyphotic deformity can become aggravated despite spinal fusion surgery, so regular and continuous follow-up is required.

OBJECTIVETo investigate the clinical effects and operative options for the treatment of Forestier disease.

METHODSFrom June 2005 to May 2012, 8 patients with progressive dysphagia due to Forestier disease were treated through anterior approach, their clinical data were retrospective analyzed. There were 6 males and 2 females, aged from 65 to 83 years old with an average of 73 years. Among the patients, osteophytes removal was performed in 3 cases, osteophytes removal with discectomy and fusion was performed in 2 cases, osteophytes removal with corpectomy and fusion was performed in 3 cases. According to Bazaz dysphagia score to assess the improvement of the patients' symptoms before and after operation.

RESULTSAll patients were followed up from 12 to 40 months with the mean of 18.5 months. Seven cases were asymptomatic and 1 case had mild symptom in the last follow-up. Radiographs showed the space enlargement between vertebral body and trachea.

CONCLUSIONIt is effective to treat patients with progressive dysphagia due to Forestier disease through surgical method. And the operative options depend on the stability of cervical spine and the neurological symptoms of the patients.
