Traumatic cervical spondyloptosis is an uncommon and severe form of facet joint dislocation that commonly leads to severe neurological damage. Decision making regarding the reduction and fixation technique is challenging, especially when a patient is neurologically intact, since an undiagnosed prolapsed disk at the involved level may lead to severe neurological consequences during reduction. A 24-year-old male was admitted after sustaining a severe direct axial blow to his head. Computed tomographic and magnetic resonance imaging scans revealed an acute C6C7 fracture dislocation with spondyloptosis of C6 vertebra and a large disk fragment posterior to C6 vertebral body. The patient was neurologically intact, apart from mild bilateral numbness over C6 distribution. The patient underwent C6 corpectomy to avoid acute cord compression related to the large sequestered disk behind C6 vertebra. Following C6 corpectomy, we were unable to exert enough axial pull to reduce the facet dislocation through the anterior approach. Therefore, the reduction was performed through a posterior approach with C5T1 posterior fusion, followed by anterior cage placement and C5-7 anterior fusion (front-back-front approach). At postoperative follow-up of 24 months, the patient demonstrated a full and pain-free cervical range-of-motion and remained neurologically intact. Follow-up radiographs of the cervical spine demonstrated good instrumental alignment with solid fusion at 6-month follow-up.

ABSTRACT OBJECTIVE AND IMPORTANCE: A 31-year-old woman presented with an avulsion fracture of the foramen magnum via bilateral occipital condyles with extension through the inferior aspect of the clivus. CLINICAL PRESENTATION: The patient had no neurological deficits and was initially immobilized in a halo brace. INTERVENTION: To preserve rotational motion at C1–C2, we performed an occiput-to-C1 fusion with bilateral C1 lateral mass screws attached with rods to occipital keel screws. Postoperatively, the patient remained neurologically intact. Three-month follow-up imaging revealed no abnormal motion. Follow-up computed tomographic scan showed an intact construct and bony fusion. CONCLUSION: This rare injury, a bony variant of occipitoatlantal dislocation, was successfully treated with a unique occiput-to-C1 fusion.

AbstractNonaccidental trauma (NAT), causing spinal injury is rare and occurs in up to 3% of cases. Management of these injuries is typically conservative, and thus surgical management is not widely reported in the literature. In this case report, we presented three patients to review the effectiveness of spinal instrumentation and posterior fusion in pediatric patients due to NAT. All patients recovered well and were neurologically intact at last follow-up with no postprocedural complications noted. Spinal arthrodesis is a safe, effective way to manage spinal injuries due to NAT in cases of fracture-dislocation, distraction injuries, as well as cases involving neurologic compromise.

Abstract Arachnoid web of the spine (AWS) is a rare and subtle lesion that can have severe neurological consequences. Patients typically present with progressive myelopathic symptoms and have no more than a slight indentation of spinal cord on imaging, commonly referred to as the “scalpel sign.” A unique feature associated with this lesion is the extent of (and sometimes the rapidity of) the recovery that occurs following treatment. In this operative video, we highlight the treatment of a 32-yr-old male with a history of lumbar spondylosis, who, over a 2 wk period, developed progressive spasticity and weakness of the entire left lower extremity and left foot numbness. Magnetic resonance imaging revealed a T4-T5 “scalpel sign” and spinal cord compression on computed topography myelogram, which was subsequently taken to the operating theater. The major steps in this video include the following: A) a summary of the patient's presentation and preoperative imaging, B) the technical steps in the surgical lysis of the AWS, and C) his postoperative course. The patient tolerated the procedure well, demonstrating a rapid improvement in symptoms postoperative day 1. At the time of most recent follow-up (4 mo), the patient remains neurologically intact with a full return to his neurologic baseline. Surgical lysis of AWS demonstrated to be a curative procedure with rapid neurological recovery, showing no signs of recurrence or regression. Consent was given by the patient for the use of deidentified images and the intraoperative video for educational purposes at the time consent was obtained for the surgical procedure, in accordance with our institution's policy.

Abstract OBJECTIVE To introduce a method for a simple, nonexpansive laminoplasty that can be performed with a threadwire saw (T-saw) after en bloc laminotomy has been performed. The method can be applied along the entire spinal region, including the thoracic and lumbar spine. METHODS An en bloc laminotomy of trapezoid shape at the cross section is performed bilaterally at the junctional area of the lamina and facet joint with a thin, flexible T-saw, while preserving the supraspinous, interspinous, and interlaminar ligaments. After the intradural procedure has been performed, the laminar flap is replaced in its original site and fixed with 1-0 nylon sutures, resulting in the complete reconstruction of the posterior supporting elements of the spinal column. RESULTS En bloc laminoplasty was performed on 16 patients via a T-saw; most of the patients had intradural spinal tumors. The patients did not need their spinal canals to be enlarged after the intradural procedure had been performed. The follow-up period ranged from 2 to 40 months (mean ± standard error, 22.6 ± 3.4 mo). The laminoplasty was performed from the upper cervical to the sacral regions, although the most frequently operated level was the lower thoracic level. Two-level laminoplasty was performed in 12 patients, and three-level laminoplasty was performed in four. The laminoplasty was done safely and without any complications, except in one patient, who experienced thoracic root injury from a T-saw that was accidentally inserted anterior to the roots. No spinal column deformity or sinking of the replaced laminar flap was noted during the follow-up period; patients were assessed at follow-up via radiographs or computed tomographic scans. Computed tomographic scans obtained later indicated that bony fusion occurred at the cutting edges 1.0 to 4.0 months after surgery (mean, 1.90 ± 0.34 mo). CONCLUSION Simple en bloc laminoplasty performed with a T-saw is a useful, safe procedure that can be used to reconstruct the posterior spinal elements throughout the whole spinal region after the intradural procedure has been performed.

Background: Forefoot gangrene in patients with diabetes is a severe form of foot ulcers with risk of progress and major amputation. No large cohort studies have examined clinical characteristics and outcome of forefoot gangrene in patients with diabetes. The aim was to examine clinical characteristics and outcome of forefoot gangrene in patients with diabetes admitted to a diabetic foot centre. Methods: Patients with diabetes and foot ulcer consecutively presenting were included if they had forefoot gangrene (Wagner grade 4) at initial visit or developed forefoot gangrene during follow-up at diabetic foot centre. Patients were prospectively followed up until final outcome, either healing or death. The median follow-up period until healing was 41 (3–234) weeks. Results: Four hundred and seventy-six patients were included. The median age was 73 (35–95) years and 63% were males. Of the patients, 82% had cardiovascular disease and 16% had diabetic nephropathy. Vascular intervention was performed in 64%. Fifty-one patients (17% of surviving patients) healed after auto-amputation, 150 after minor amputation (48% of surviving patients), 103 had major amputation (33% of surviving patients) and 162 patients deceased unhealed. Ten patients were lost at follow-up. The median time to healing for all surviving patients was 41 (3–234) weeks; for auto-amputated, 48 (10–228) weeks; for minor amputated, 48 (6–234) weeks; and for major amputation, 32 (3–116) weeks. Conclusion: Healing without major amputation is possible in a large proportion of patients with diabetes and forefoot gangrene, despite these patients being elderly and with extensive co-morbidity.

Abstract Background Percutaneous vertebroplasty (PVP) and kyphoplasty (PKP) have been widely used to treat neurologically intact osteoporotic Kümmell’s disease (KD), but it is still unclear which treatment is more advantageous. Our study aimed to compare and investigate the safety and clinical efficacy of PVP and PKP in the treatment of KD. Methods The relevant data that 64 patients of neurologically intact osteoporotic KD receiving PVP (30 patients) or PKP (34 patients) were analyzed. Surgical time, operation costs, intraoperative blood loss, volume of bone cement injection, and fluoroscopy times were compared. Occurrence of cement leakage, transient fever and re-fracture were recorded. Universal indicators of visual analogue scale (VAS) and Oswestry disability index (ODI) were evaluated separately before surgery and at 1 day, 6 months, 1 year, 2 years and the final follow-up after operation. The height of anterior edge of the affected vertebra and the Cobb’s angle were assessed by imaging. Results All patients were followed up for at least 24 months. The volume of bone cement injection, intraoperative blood loss, occurrence of bone cement leakage, transient fever and re-fracture between two groups showed no significant difference. The surgical time, the operation cost and fluoroscopy times of the PKP group was significantly higher than that of the PVP group. The post-operative VAS, ODI scores, the height of the anterior edge of the injured vertebrae and kyphosis deformity were significantly improved in both groups compared with the pre-operation. The improvement of vertebral height and kyphosis deformity in PKP group was significantly better than that in the PVP group at every same time point during the follow-up periods, but the VAS and ODI scores between the two groups showed no significant difference. Conclusion PVP and PKP can both significantly alleviate the pain of patients with KD and obtain good clinical efficacy and safety. By contrast, PKP can achieve better imaging height and kyphosis correction, while PVP has the advantages of shorter operation time, less radiation volume and operation cost.

AbstractThe aim of the present study was to present clinical and radiological outcome of a hip fracture-dislocation of the femoral head treated with biomimetic osteochondral scaffold.An 18-year-old male was admitted to the hospital after a motorcycle-accident. He presented with an obturator hip dislocation with a type IVA femoral head fracture according to Brumback classification system. The patient underwent surgery 5 days after accident. The largest osteochondral fragment was reduced and stabilized with 2 screws, and the small fragments were removed. The residual osteochondral area was replaced by a biomimetic nanostructured osteochondral scaffold. At 1-year follow-up the patient did not complain of hip pain and could walk without limp. At 2-year follow-up he was able to run with no pain and he returned to practice sports. Repeated radiographs and magnetic resonance imaging studies of the hip showed no signs of osteoarthritis or evidence of avascular necrosis. A hyaline-like signal on the surface of the scaffold was observed with restoration of the articular surface and progressive decrease of the subchondral edema.The results of the present study showed that the biomimetic nanostructured osteochondral scaffold could be a promising and safe option for the treatment of traumatic osteochondral lesions of the femoral head.Study Design: Case report.

Abstract Background Isolated fractures of the ulnar head are rare. Only few cases have been reported in literature. Case Description We report a case of a 16-year-old student who was treated for an ulnar styloid fracture conservatively. An associated displaced intraarticular fracture of the ulnar head has been overlooked. He presented late in our clinic with a symptomatic nascent malunion of the ulnar head fracture. A corrective osteotomy by a palmar approach was performed. Fixation by screws was used with an excellent result at 7-year follow-up. Literature Review The rare cases of isolated ulnar head fractures reported in literature were treated by open reduction and internal fixation only in case of fracture dislocation. Clinical Relevance The authors highlight the fact that even a nascent malunion of an isolated intraarticular fracture of the ulnar head may be treated successfully by open reduction and internal fixation.

Central vein perforation associated with a mediastinal lesion is a rare complication of catheterization. A 50-year-old woman was diagnosed with chronic kidney disease and required hemodialysis treatment. The patient developed central vein injury during attempted placement of a double-channel catheter. A computed tomographic scan and venography showed that the catheter had punctured the mediastinum from the central vein. After comprehensive assessment and multidisciplinary consultation, percutaneous catheter thrombin injection with follow-up balloon dilatation under fluoroscopy guidance successfully fixed the perforation. We summarize the therapeutic strategy of this complication and other treatment options, and discuss the related literature of central vein injury.
