Acute gastric volvulus is a life-threatening condition, but its intermittent nature and vague symptoms may make diagnosis difficult. Imaging is usually only diagnostic if carried out when patients are symptomatic. The population affected ranges from paediatric age group to elderly with multiple co-morbidities. Laparoscopic repair is advisable once a diagnosis is reached. This review on gastric volvulus focuses on the diagnostic and management challenges encountered, together with strategies for dealing with them. Lessons have emerged which may assist in dealing with such a rare presentation in future.

There is extensive preclinical research supporting the use of biological therapies to augment ACLR. Further clinical studies that meet the minimum standards of reporting are required to determine whether emerging biological strategies will provide tangible benefits in patients undergoing ACLR.

BackgroundTears of the rotator cuff are one of the most common tendon disorders. Treatment often includes surgical repair, but the rate of failure to gain or maintain healing has been reported to be as high as 94%. This has been substantially attributed to the inadequate capacity of tendon to heal once damaged, particularly to bone at the enthesis. A number of strategies have been developed to improve tendon-bone healing, tendon-tendon healing, and tendon regeneration. Scaffolds have received considerable attention for replacement, reconstruction, or reinforcement of tendon defects but may not possess situation-specific or durable mechanical and biological characteristics.PurposeTo provide an overview of the biology of tendon-bone healing and the current scaffolds used to augment rotator cuff repairs.Study DesignSystematic review; Level of evidence, 4.MethodsA preliminary literature search of MEDLINE and Embase databases was performed using the terms rotator cuff scaffolds, rotator cuff augmentation, allografts for rotator cuff repair, xenografts for rotator cuff repair, and synthetic grafts for rotator cuff repair.ResultsThe search identified 438 unique articles. Of these, 214 articles were irrelevant to the topic and were therefore excluded. This left a total of 224 studies that were suitable for analysis.ConclusionA number of novel biomaterials have been developed into biologically and mechanically favorable scaffolds. Few clinical trials have examined their effect on tendon-bone healing in well-designed, long-term follow-up studies with appropriate control groups. While there is still considerable work to be done before scaffolds are introduced into routine clinical practice, there does appear to be a clear indication for their use as an interpositional graft for large and massive retracted rotator cuff tears and when repairing a poor-quality degenerative tendon.

We report our experience with glenohumeral arthrodesis as a salvage procedure for epilepsy-related recurrent shoulder instability. A total of six patients with epilepsy underwent shoulder fusion for recurrent instability and were followed up for a mean of 39 months (12 to 79). The mean age at the time of surgery was 31 years (22 to 38). Arthrodesis was performed after a mean of four previous stabilisation attempts (0 to 11) in all but one patient in whom the procedure was used as a primary treatment. All patients achieved bony union, with a mean time to fusion of 2.8 months (2 to 7). There were no cases of re-dislocation. One revision was undertaken for loosening of the metalwork, and then healed satisfactorily. An increase was noted in the mean subjective shoulder value, which improved from 37 (5 to 50) pre-operatively to 42 (20 to 70) post-operatively although it decreased in two patients. The mean Oxford shoulder instability score improved from 13 pre-operatively (7 to 21) to 24 post-operatively (13 to 36). In our series, glenohumeral arthrodesis eliminated recurrent instability and improved functional outcome. Fusion surgery should therefore be considered in this patient population. However, since the majority of patients are young and active, they should be comprehensively counselled pre-operatively given the functional deficit that results from the procedure.

Warthin tumour is the second most common benign neoplasm of the parotid gland. It has a low rate of growth and exhibits malignant transformation in 0.3% of cases. Although its aggressiveness has not been a concern, surgical resection remains the most common treatment modality. This entails the risk of a general anaesthetic and those pertaining to the procedure itself, most notably permanent facial nerve damage. This has led some authors to use conservative management, albeit rarely. There are those who condemn such a policy despite the encouraging results reported thus far. To understand the rationale underpinning non-operative management, it is imperative that one has a comprehensive understanding of the pathogenesis, clinical presentation and diagnosis of Warthin tumour. The aim of this review therefore is to detail these elements and clarify the current controversies in managing this lesion.

The application of DBM to a rat model of chronic rotator cuff degeneration did not improve the composition of the healing enthesis compared with nonaugmented controls and a commercially available scaffold. However, perhaps the most important finding of this study was that the control group demonstrated a similar outcome to augmented repairs.

Background:Ankle fracture fixation is one of the most commonly performed orthopaedic procedures. Although the results are generally favourable, complications are not uncommon, particularly in the case of surgical site infections. These have considerable impact on both postoperative morbidity and healthcare costs. Paradoxically, there is a paucity of literature studying patients who sustain them and therefore little is known about ways such occurrences can be minimised. The purpose of this study was to determine the infection rate following ankle fracture fixation and elucidate variables in their causation.Methods:We retrospectively reviewed 50 consecutive patients who underwent open reduction and internal fixation of an ankle fracture. The study group consisted of 26 females and 24 males with an average age of 43 (Range 16-82) years.Results:Problems with superficial infections were noted in seven patients and deep infections in five. Of the latter, four patients underwent further surgery including two that had their metal work removed. With use of the Fisher’s exact test we determined that only smoking and a bimalleolar fracture pattern were significant variables, having p-values of 0.02 and 0.04 respectively.Conclusion:We recommend that patients with ankle fractures who either have a history of smoking and/or bimalleolar injury be counselled about the potential risk of infection and its implications on their functional recovery. The ability to identify patients at risk of such problems highlights the need for caution during the perioperative period so that care strategies may be altered to facilitate recovery.
