Neglected medial swivel dislocation of talonavicular joint with calcaneus,cuboid and 5th metatarsal fractures – A case report

Talonavicular dislocation is a rare injury. Isolated medial or lateral talonavicular dislocations without disruption of subtalar joint are known as medial or lateral swivel dislocations respectively, both being extremely rare. We describe a rare case of neglected medial swivel dislocation with concomitant calcaneus, cuboid and 5th metatarsal fracture, which was managed with open reduction and fixation of talonavicular joint with k-wires and an external distractor. At 1 year follow up the patient was mobilizing full weight bearing without any pain or deformity, the radiographs showing well located talonavicular joint and healed calcaneus, cuboid and 5th metatarsal fractures. This is the first reported case of medial swivel talonavicular dislocation with associated calcaneum, cuboid and 5th metatarsal fracture to the best of our knowledge. This case report highlights the importance of maintaining high level of suspicion for diagnosing midfoot injuries in a polytraumatized patient as well as need of accurate and timely reduction of dislocation for good functional outcome.Level of clinical evidenceLevel 4.     

Flexor Tenosynovectomy for Recurrent Carpal Tunnel Syndrome: A Retrospective Case Series of 108 Hands

Background: The etiology of recurrent carpal tunnel syndrome (CTS) is unclear, and outcomes following secondary surgery in this demographic have been poorer than primary surgery. Fibrosis and hypertrophy have been identified in the flexor tenosynovium in these patients. The authors use flexor tenosynovectomy (FTS) for recurrent CTS after primary carpal tunnel release and present a review of these patients. Methods: A retrospective chart review was performed of 108 cases of FTS for recurrent CTS from 1995 to 2015 by 4 attending surgeons at one institution. Demographic information, symptoms, and outcomes were among the data recorded. A phone survey was conducted on available patients where the shortened version of the Disabilities of the Arm, Shoulder and Hand Questionnaire (QuickDASH) and satisfaction were assessed. Results: Average office follow-up was 12 months. Average age was 57.5 years. A total of 104 (96%) reported symptom improvement and 48 (44%) reported complete symptom resolution. Forty patients were available for long-term follow-up at an average 6.75 years postoperatively via phone interview. Average QuickDASH score was 31.2 in these patients. Thirty-six (90%) of 40 patients were initially satisfied at last office visit, and 31 (78%) of 40 were satisfied at average 6.9 years, a maintenance of satisfaction of 86%. Satisfied patients were older (58 years) than unsatisfied patients (51 years). Conclusion: Both long-term satisfaction and QuickDASH scores in our cohort are consistent with or better than published results from nerve-shielding procedures. The authors believe a decrease in both carpal tunnel volume and potential adhesions of fibrotic or inflammatory synovium contributes to the benefits of this procedure. This remains our procedure of choice for recurrent CTS.     

The osseous structure of the carpal groove

Summary Transverse osseous structure of the carpal groove was studied using serial sections and microradiography. The width and area of the carpal groove were measured in x-ray films of each section. The wrist and carpal region was divided into six levels: 1) radio-ulnar joint level, 2) proximal level of the carpal bones, 3) intermediate level of carpal bones, 4) distal level of carpal bones, 5) the first C-M joint level, and 6) bases of the metacarpal bone level. The width of the carpal groove averaged 32 mm at the inlet and became narrower toward the outlet. Both inlet and outlet areas were small, the largest area was observed at the middle part. Although the carpal bones did not support the body weight, a remnant of the trajectorial architecture of the trabeculae was observed.

La structure osseuse de la gouttière carpienne

Résumé La structure transversale des os de la gouttière carpienne a été étudiée à l'aide de coupes et par microradiographie. L'épaisseur et la superficie de la gouttière carpienne ont été mesurées sur des clichés aux rayons X de chacune de ces coupes. La région du poignet et du carpe a été divisée en six rangées: 1) la rangée de l'articulation radiocubitale, 2) la rangée proximale des os du carpe, 3) la rangée intermédiaire des os du carpe, 4) la rangée distale des os du carpe, 5) la rangée de la première articulation C-M et 6) la rangée de la base des os du métacarpe. L'épaisseur moyenne de la gouttière carpienne atteignait 32 mm à l'entrée, se rétrécissant en direction de la sortie. Tant la zone d'entrée que celle de sortie étaient de superficie réduite, la superficie la plus importante étant observée dans la partie médiane. Si les os du carpe ne supportent pas le poids du corps, un reste de structure trajectorielle des travées a cependant été observé.

Traumatic testicular dislocation: A case report and literature review

Introduction:Traumatic testicular dislocation is an uncommon complication of blunt scrotal injury and is easily overlooked because of the presence of other severe accompanying injuries. In most cases, an operation is needed for the prevention of malignant change or infertility.Patient concerns and diagnosis:We report a case of traumatic testicular dislocation with pelvic fracture and internal bleeding in a 27-year-old male with testis rupture after a motorcycle collision.Interventions and outcomes:He received emergent right radical orchiectomy, and a series of operations for femoral and pelvic fractures were performed after his condition stabilized in the intensive care unit. After 1 month postsurgery, no obvious genitourinary complications were noted.Conclusion:We suggest scrotum examination in all trauma patients, particularly if a pelvic injury is suspected or in case of a high risk of a motorcycle collision, to avoid missing the diagnosis and prevent severe complications     

A case report on a child with fracture and dislocation of the upper cervical spine accompanied by spinal cord injury

Rationale:This study describes an 8-year-old boy with a C2 fracture and dislocation with a left C2–C3 articular process interlocking and spinal cord injury who underwent open reduction and internal fixation using the posterior cervical approach and achieved satisfactory results.Patient concerns:An 8-year-old boy underwent an emergency transfer from a previous hospital after a car accident.Diagnoses:Axial fracture and dislocation with spinal cord injury (American Spinal Injury Association grade C), traumatic shock, brain contusion, intracranial hemorrhage, mandibular fracture, pulmonary contusion and hemorrhage, left vertebral artery stenosis, and multiple fractures throughout the body. Radiological examination revealed a fracture of the lower edge of the C2 vertebral body, fourth-degree anterior spondylolisthesis of the C2 vertebral body, interlocking of the left C2–C3 articular processes, widening of the C2–C3 vertebral space, and occlusion of the V1 and 2 segments of the left vertebral artery.Interventions:The boy was immediately intubated and transferred to the pediatric intensive care unit for rescue treatment. However, the reduction was unsuccessful with 2 weeks of cranial traction. Thus, an open reduction was performed under general anesthesia. One month after the surgery, the boy was discharged from the hospital on foot after rehabilitation treatment.Outcomes:The boy was discharged from the hospital 1 month after surgery. At the 8-month follow-up, a radiological examination showed that the corrected C2 vertebral body fracture and dislocation were satisfactorily reduced, and the spinal cord was adequately decompressed. The internal fixation position was also good, and the spinal sequence had recovered well. In summary, except for the muscle strength of the right upper limb, which was slightly worse, the other clinical symptoms were significantly improved.Lessons:In treating cervical fracture and dislocation with unilateral facet lock, the posterior open reduction of pedicle screw and lateral mass screw internal fixation achieved satisfactory results. Consequently, treating complex cervical spine injuries in children requires an accurate diagnosis and careful treatment strategy.
