Study Design. Retrospective review of prospective case-control study. Objective. To compare minimally invasive scoliosis surgery (MIS) and posterior spinal fusion (PSF) in a large group of patients. Summary of Background Data. MIS, has been shown to have benefits over standard PSF in adolescent idiopathic scoliosis (AIS). Methods. Radiographic, clinical, and operative review of a multi-institutional prospective database from 2013 to 2018. MIS patients with minimum 2-year XR follow up were compared with open PSF technique patients. Results. Four hundred eighty five patients were included; 192 MIS and 293 PSF. Preoperative Cobb (P ¼ 0.231) and kyphosis were similar (P ¼ 0.501). Cobb correction was comparable (P ¼ 0.46), however percent improvement in thoracic kyphosis was significantly higher in MIS (P < 0.001). MIS had significantly lower blood loss (P < 0.001), transfusions (P < 0.001), fixation points (P < 0.001), opioid consumption (P ¼ 0.001), and hospital stay (P < 0.001). Operative time was shorter (P ¼ 0.001) and 30day complications rate was similar (P ¼ 0.81). Conclusion. This is the largest study comparing the surgical outcomes of MIS and PSF. MIS patients benefit from increased kyphosis, fewer transfusion, lower opioid consumption, and shorter hospital stay with similar Cobb correction. Increased postoperative kyphosis is likely from muscle sparing dissection in MIS.
For the patient (and the surgeon) the ideal wrist is one that has good mobility, however very often the optimal surgical treatment is one that provides effective pain relief. The patient must be informed of the potential complications and limitations of each procedure. The patient's psychological profile and functional requirements will determine how well he/she adapts to the changes. Also, each surgeon has beliefs and personal experiences that influence the treatment decision and final result. Proximal row carpectomy (PRC) and the Watson procedure are two reference operations for osteoarthritis secondary to scapholunate instability and scaphoid non-union (SLAC and SNAC). Beyond the early complications and drawbacks specific to each, they provide good results that are maintained over time. PRC, which can be performed up to Stage II, is mainly indicated in patients with moderate functional demands, while the Watson procedure is more often done on a patient who performs manual labour, as long as the radiolunate joint space is maintained. Complete denervation is effective in three out of four cases and preserves the remaining mobility. Because of its low morbidity, the procedure can be suggested in patients with a mobile wrist and low functional demands or in older patients, independent of their wrist mobility. Total wrist fusion is not only a rescue procedure. For a young patient who performs heavy manual labour with extensive osteoarthritis and progressive forms of Kienböck's disease, this procedure provides the greatest chance of returning to work and not being socially outcast. The role of osteochondral autografts, implants and wrist prostheses in the treatment arsenal need to be better defined.
Rationale:Obturator pyomyositis is a rare condition in children. Diagnosis is often delayed because of its rarity, and the vagaries of its presentation cause it to be easily be missed. Physicians should therefore familiarize themselves with this condition and consider it as a possible differential diagnosis in patients presenting with an acutely painful hip. Inflammatory syndrome is also frequent among sufferers and the MRI is a very sensitive diagnostic tool for obturator pyomyositis. Additionally, joint fluid aspirations and blood cultures are also useful in identifying the pathogen. The appropriate antibiotic therapy provides a rapid regression of symptoms during the early stage of pyomyositis. In cases of MRI-confirmed abscess, surgical treatment is indicated.Patient concerns:Our report focuses on a case of obturator pyomyositis in a 9-year-old boy. The child was febrile for 5 days and could only manage to walk a few steps. His hip range of motion was restricted in all directions. In addition, the patient had presented pain and swelling of his right elbow for a day, with a restriction of motion in the joint. There was a clear inflammatory syndrome. A diagnosis of hip and elbow septic arthritis was suspected, and the child underwent joint aspiration of the both cited joints. The aspiration of the elbow returned pus. Conversely, no effusion was found in the hip aspiration. The administration of empiric intravenous antibiotherapy was started.Diagnoses:An MRI revealed an osteomyelitis of the ischio-pubic area associated with a subperiosteal abscess.Interventions:Subsequently, 3 days after elbow arthrotomy, a surgical treatment was performed on the patient's right hip in order to evacuate the subperiosteal abscess and muscular collection because of the persistence of the patient's symptoms and inflammatory syndrome despite susceptible intravenous antibiotics. Postsurgery the patient showed steady improvement.Lessons:Such cases demonstrate how diagnosis can be difficult because pelvic pyomyositis is often mistaken for more common pathologies such as septic arthritis, osteomyelitis, or appendicitis. This may delay the diagnosis or refer misdiagnosis. We discuss this rare infection in light of the literature with particular reference to its incidence, clinical features, bacteriological etiology, biological, and radiological presentation, and above all, its treatment.
