ABSTRACT
Context: One of the main causes of chronic facial pain is temporomandibular disorders (TMDs) which may turn out to be a major cause for disability. The two types of treatment strategies may be undertaken to counter temporomandibular joint (TMJ) disorders, namely conservative management and surgical intervention. Surgical management can be classified into invasive open methods and minimally invasive procedures such as arthrocentesis, intra-articular steroid injection, and arthroscopy. Aims: The aim of this study is to compare the efficacy of Kenacort (Triamcinolone) as an intra-articular corticosteroid injection and arthrocentesis for lysis and lavage, for the treatment of the temporomandibular joint disorders. Subjects and Methods: Twenty patients with internal derangement of temporomandibular joint (IDTMJ) not responding to conservative management and meeting the inclusion criteria randomly underwent either intra-articular steroid injection or arthrocentesis and the results of the two procedures were evaluated and compared. Statistical Analysis Used: Unpaired t-test, repeated-measures ANOVA. A value of P < 0.05 is considered to be statistically significant. Results and Conclusion: Both procedures turned out to be successful in reducing pain and improving mouth opening, both in a short-term and a long-term use. Upon comparison in our series of patients, arthrocentesis was noted to be a better treatment modality in the long term for the management of IDTMJ.
ABSTRACT
BACKGROUND: There are no reports describing complications with posterior spinal fusion (PSF) with segmental spinal instrumentation (SSI) using pedicle screw fixation in patients with neuromuscular scoliosis. METHODS: Fifty neuromuscular patients (18 cerebral palsy, 18 Duchenne muscular dystrophy, 8 spinal muscular atrophy and 6 others) were divided in two groups according to severity of curves; group I (< 90 degrees ) and group II (> 90 degrees ). All underwent PSF and SSI with pedicle screw fixation. There were no anterior procedures. Perioperative (within three months of surgery) and postoperative (after three months of surgery) complications were retrospectively reviewed. RESULTS: There were fifty (37 perioperative, 13 postoperative) complications. Hemo/pneumothorax, pleural effusion, pulmonary edema requiring ICU care, complete spinal cord injury, deep wound infection and death were major complications; while atelectesis, pneumonia, mild pleural effusion, UTI, ileus, vomiting, gastritis, tingling sensation or radiating pain in lower limb, superficial infection and wound dehiscence were minor complications. Regarding perioperative complications, 34(68%) patients had at least one major or one minor complication. There were 16 patients with pulmonary, 14 with abdominal, 3 with wound related, 2 with neurological and 1 cardiovascular complications, respectively. There were two deaths, one due to cardiac arrest and other due to hypovolemic shock. Regarding postoperative complications 7 patients had coccygodynia, 3 had screw head prominence, 2 had bed sore and 1 had implant loosening, respectively. There was a significant relationship between age and increased intraoperative blood loss (p = 0.024). However it did not increased complications or need for ICU care. Similarly intraoperative blood loss > 3500 ml, severity of curve or need of pelvic fixation did not increase the complication rate or need for ICU. DMD patients had higher chances of coccygodynia postoperatively. CONCLUSION: Although posterior-only approach using pedicle screw fixation had good correction rate, complications were similar to previous reports. There were few unusual complications like coccygodynia.
ABSTRACT
This article studies the incidence and magnitude of delayed callus subsidence, which will also help in study the hypothesis of three cortex corticalisation to determine the time of fixator removal during distraction osteogenesis (DO). Eighty-one tibia segments with mean lengthening of 7.7 +/- 2.9 cm were studied with age, gender, skeletal maturity, amount and percentage of lengthening, callus pattern, callus shape, number of cortices seen at the time of fixator removal, bone mineral density (BMD) ratio, and callus diameter ratio analysed for their effect on callus subsidence. All segments had tibia callus subsidence ranging from 4 mm to 3.2 cm with 54% having significant subsidence of more than 1 cm. Multivariate regression analysis revealed only the amount of lengthening and callus patterns to be significant. In conclusion, we can say that tibia callus subsidence is a significant delayed complication and factors affecting it can be used to determine the time of fixator removal.
