RESUMO

Introduction: Both knotted all suture anchors and metal anchors are used for arthroscopic Bankart repair. We retrospectively evaluated and compared clinical and functional outcomes after arthroscopic Bankart repair using the knotted all-suture anchors and knotted metal anchors. Materials and methods: In a retrospective cohort analysis, patients who underwent arthroscopic Bankart repair without any concomitant additional lesion repair using either all-suture anchors or metal anchors, between January 2015 and May 2018 were identified. Their pre- and post-operative functional and clinical outcomes were compared using Rowe and WOSI scores. The recurrence rate in the two groups was also compared. Results: A total of 41 patients in all suture anchors group and 47 in the metal anchors group were identified as per inclusion and exclusion criteria. The demographic profile of both groups was comparable. There was no significant difference in clinical and functional outcome between the two suture anchor groups as per Rowe (pre-operative 40.13+6.51 vs 38.09+6.24 and post-operative 2 years 93.28+7.09 vs 92.55+9.2) and WOSI (pre-operative 943.05+216.64 vs 977.55+165.46 and post-operative 2 years 278.21+227.56 vs 270.94+186.25) scores. There was a significant improvement in both the groups between preoperative and post-operative ROWE and WOSI scores at 6 months and 2 years follow-up as compared to pre-operative scores (p<0.001). Re-dislocation rates were also comparable (4.8% vs 6.3%). Conclusion: All-suture anchors showed comparable clinical and functional results as the metal anchors for arthroscopic Bankart repair at two-year follow-up.

RESUMO

INTRODUCTION: An increased tibial tuberosity-trochlear groove (TTTG) distance is used for deciding a treatment plan in patello-femoral instability (PFI). The centre of the patellar tendon and the chondral trochlear groove can be directly visualised on MRI, and measured, giving the patellar tendon-trochlear groove (PTTG) distance. A study was designed to compare the inter-rater and the test-retest reliabilities of PTTG and TTTG measurements in MRI of patients without PFI and in a group with PFI. MATERIALS AND METHODS: This cross-sectional reliability study was done on archival MRI films of 50 patients without patellar instability and 20 patients with patellar instability. TTTG and PTTG distances were independently measured by two orthopaedic surgeons and two radiologists. A hybrid PTTG measurement with bony landmarks on the femoral side and the patellar tendon landmark on the tibial side, was used to estimate the influence of the differences in the femoral and tibial landmarks on the difference in reliabilities. The intra-class correlation coefficient (ICC) was calculated for all four raters, as well as separately for each rater. RESULTS: The PTTG distance had a higher inter-rater reliability (ICC=0.86, 95% CI=0.79-0.92) compared to the TTTG distance (ICC=0.70, 95% CI=0.59-0.80) in patients without PFI. Similar trends were seen in patients with PFI (0.83 vs 0.66). The inter-rater reliability for the hybrid PTTG distance was found to lie in between the TTTG and PTTG. CONCLUSIONS: The MRI-based PTTG distance had better inter-rater reliability compared with the MRI-based TTTG distance.

RESUMO

Open reduction and internal fixation of high-energy pilon fractures are often associated with serious complications. Various methods have been used to treat these injuries, with variable results. A total of 17 consecutive patients with pilon fractures of AO/OTA type 43-B3 (n = 1), type C2 (n = 12) and type C3 (n = 4) were treated by indirect reduction by capsuloligamentotaxis and stabilisation using an ankle-spanning Ilizarov fixator. The calcaneal ring was removed at a mean of 3.7 weeks (3 to 6). A total of 16 patients were available for follow-up at a mean of 29 months (23 to 43). The mean time to healing was 15.8 weeks (13 to 23). Nine patients had pin-track infections but none had deep infection or osteomyelitis. Four patients (25%) had malunion. Fair, good or excellent ankle scores were found in 14 patients. External fixation with a ring fixator achieves stable reduction of the fractured fragments without additional trauma to soft tissues. With minimum complications and good healing results, the Ilizarov apparatus is particularly useful for high-energy pilon fractures.

RESUMO

PURPOSE: To assess results of small wire external fixation using a ligamentotaxis technique for high-energy tibial plateau fractures. METHODS: Between April 2002 and May 2004, 38 consecutive patients aged 21 to 60 (mean, 32) years underwent small wire external fixation for high-energy tibial plateau fractures. 15 involved the right and 23 the left knee. 34 were closed and 4 were open injuries. Fractures were classified according to Schatzker's staging system. After a minimal of 2 years' follow-up (range, 24-42 months), each affected knee was evaluated using Rasmussen's (1) 30-point clinical grading system and (2) radiological evaluation. RESULTS: There were 22 type-VI and 16 type-V Schatzker tibial plateau fractures. Complications consisted of: 2 superficial infections, 3 pin site infections, and 4 peroneal nerve palsies. No soft tissue necrosis or devitalisation occurred. The mean range of knee movement was 132 degrees. The mean Rasmussen radiological score was 14 (range, 10-18): excellent in 6, good in 26, and fair in 6. The mean Rasmusssen functional score was 26 (range, 17-30): excellent in 19 patients, good in 17, and fair in 2. Clinical results did not parallel the radiological results. CONCLUSION: Small wire external fixation allows anatomical reconstruction of the articular surface, stable fixation of fracture fragments, early movement of the joint, and care of associated soft tissue injuries, without a high rate of complications.

RESUMO

Acquired radial club hand caused by infection has been reported occasionally. We report a rare case of acquired radial club hand with an associated septic dislocation of the elbow, primarily caused by compartment syndrome following venous cannulation. The deformity and instability were treated with distraction using an external fixator followed by a centralisation procedure. At the 2-year follow-up the appearance and functions of the left forearm had improved considerably and the wrist was stable. There was no deterioration in ulnar growth.

RESUMO

Effect of benomyl and thiophanate-methyl on various metabolic activities of Rhizoctonia solani was investigated. Both fungitoxicants strongly reduced endogenous whole cell and mitochondrial respiration by inhibiting one or the other key enzymes of electron transport chain; the activity of cytochrome oxidase being most markedly inhibited. Incorporation of 3II-thymidine was reduced by both while there was little or no inhibition in the rate of incorporation of 14C-uracil and 14C-leucine. Cell permeability was not affected to any appreciable extent and there was a little release of cellular components from the treated cells only at prolonged incubation. It is concluded that benomyl and thiophanate-methyl have a similar mode of action which primarily involves inhibition of respiratory activities, and as a consequence the biosynthesis of DNA is reduced.
