The versatility of the medial thigh lift for defect coverage in the genito-perineal region

Soft tissue defects in the genito-perineal region are predominantly because of trauma, infections, neoplasms or iatrogenic causes. As a result of the region's urological, reproductive and gastrointestinal function, defects in this area may cause devastating physical and psychological consequences as well as diminished sexual functioning. The purpose of this study was to examine the efficacy of implementing a medial thigh lift for defect coverage in the perineal region. A retrospective analysis of all medial thigh lift procedures for defect coverage in the genito-perineal region between November 2010 and March 2015 was conducted at three institutions. Ten consecutive patients underwent a medial thigh lift for defect coverage in the genito-perineal region. Nine patients were male, and one was female. The causative factors were Fournier's gangrene in eight patients, one patient had a straddle injury, and one suffered from extramammary Paget's disease. The mean follow-up time was 19·8 months. The average total defect size was 11·1 × 11 cm (length × width). The medial thigh lift procedure is a safe, technically easy and reliable technique with discrete scars. Outstanding aesthetic and functional outcomes result in a high rate of patient satisfaction. Through immediate wound closure, a reduction of recovery time can be achieved.

Patterns and management of degloving injuries: a single national level 1 trauma center experience

Background

Degloving soft tissue injuries (DSTIs) are serious surgical conditions. We aimed to evaluate the pattern, management and outcome of DSTIs in a single institute.

Methods

A retrospective analysis was performed for patients admitted with DSTIs from 2011to 2013. Presentation, management and outcomes were analyzed according to the type of DSTI.

Results

Of 178 DSTI patients, 91 % were males with a mean age of 30.5 ± 12.8. Three-quarter of cases was due to traffic–related injuries. Eighty percent of open DSTI cases were identified. Primary debridement and closure (62.9 %) was the frequent intervention used. Intermediate closed drainage under ultrasound guidance was performed in 7 patients; however, recurrence occurred in 4 patients who underwent closed serial drainage for recollection and ended with a proper debridement with or without vacuum assisted closure (VAC). Closed DSTIs were mainly seen in the lower extremity and back region and initially treated with conservative management as compared to open DSTIs. Infection and skin necrosis were reported in 9 cases only. Open DSTIs were more likely involving head and neck region and being treated by primary debridement/suturing and serial debridement/washout with or without VAC. All-cause DSTI mortality was 9 % that was higher in the closed DSTIs (19.4 vs 6.3 %; p = 0.01).

Conclusion

The incidence of DSTIs is 4 % among trauma admissions over 3 years, with a greater predilection to males and young population. DSTIs are mostly underestimated particularly in the closed type that are usually missed at the initial presentation and associated with poor outcomes. Treatment guidelines are not well established and therefore further studies are warranted.

Sustained cutaneous vasoconstriction during and following cyrotherapy treatment: Role of oxidative stress and Rho kinase

Cryotherapy is a therapeutic technique using ice or cold water applied to the skin to reduce bleeding, inflammation, pain, and swelling following soft tissue trauma and injury. While beneficial, there are some side effects such as pronounced vasoconstriction and tissue ischemia that are sustained for hours post-treatment. This study tested the hypothesis that this vasoconstriction is mediated by 1) the Rho-kinase pathway and/or 2) elevated oxidative stress. 9 subjects were fitted with a commercially available cryotherapy unit with a water perfused bladder on the lateral portion of the right calf. Participants were instrumented with three microdialysis probes underneath the bladder. One site received lactated ringers (control site), one received the Rho-Kinase inhibitor Fasudil, and one received Ascorbic Acid. Skin temperature (Tskin) and cutaneous vascular conductance (CVC) was measured at each site. Subjects had 1°C water perfused through the bladder for 30min, followed by passive rewarming for 90min. Tskin fell from ~34°C to ~18.0°C during active cooling across all sites and this response was similar for all sites (P>0.05 for all comparisons). During passive rewarming Tskin rose to a similar degree in all sites (P>0.05 relative to the end of cooling). %CVC was reduced during active cooling in all sites; however, the magnitude of this response was blunted in the Fasudil site relative to control (P<0.001 for all comparisons) and min 25 and 30 of cooling in the Ascorbic Acid site (P<0.05). During passive rewarming %CVC at the control and Ascorbic Acid sites did not change such that values were similar to the end of cooling (P>0.05 for each comparison). %CVC at the Fasudil site remained elevated during passive rewarming such that values were higher compared to the control and Ascorbic Acid sites throughout the 90min of passive rewarming (P<0.001 main effect of Fasudil). These findings indicate that the Rho-kinase pathway contributes to pronounced vasoconstriction during cryotherapy as well as the sustained vasoconstriction during the subsequent rewarming period post treatment.

Management of the Morel-Lavallée Lesion

Morel-Lavallée lesions are closed degloving injuries sustained during violent soft tissue shear that separate the subdermal fat from its strong underlying fascia. Lesions most often occur in the peritrochanteric region, and patients may have concomitant polytrauma. As a result, a hematoma develops that has a high rate of acute bacterial colonization and chronic recurrence. Conservative treatment outcomes are best for those managed acutely. However, diagnosis is often delayed or missed. Furthermore, there is no universally accepted treatment algorithm. Diagnosis and treatment depend on a surgeon's thorough understanding of the cause, pathophysiology, imaging characteristics, and treatment options of Morel-Lavallée lesions.

Large Morel-Lavallée lesion presenting as fungating mass with skin ulceration

A Morel-Lavallée lesion, a type of soft tissue degloving injury that has also been referred to as a chronic expanding hematoma, is a relatively rare condition that usually develops following traumatic injury. Here, we present a case of a 60-year-old male with a Morel-Lavallée lesion diagnosed over 5 years after a traumatic injury of the hip. He presented with a large fungating mass and overlying skin ulceration, which was highly suspicious for sarcoma. However, lack of other systemic findings and constitutional complaints, as well as negative imaging studies, did not support a diagnosis of malignancy. This information, combined with the history of remote trauma to the affected area, instead led us to suspect the alternative diagnosis of a Morel-Lavallée lesion. The diagnosis was later confirmed by pathology showing a chronic expanding hematoma. To our knowledge, a Morel-Lavallée lesion presenting as a fungating mass has not been previously described.

The health status of people claiming compensation for musculoskeletal injuries following road traffic crashes is not altered by an early intervention programme: a comparative study

OBJECTIVE

To compare health outcomes among claimants compared to those who were ineligible or choose not to lodge a compensation claim. We also evaluated the effect of an early intervention programme on the health outcomes of the participants.

DESIGN

Prospective comparative study using sequential cohorts.

SUBJECTS

People presenting to hospital emergency departments with mild to moderate musculoskeletal injuries following road traffic crashes.

INTERVENTION

referral to an early intervention programme for assessment by musculoskeletal physician, pain management education, promotion of self-management and encouragement of early activity.

MAIN OUTCOMES

The 36-Item Short-Form Survey (SF-36); Hospital Anxiety and Depression Scale (HADS) and Functional Rating Index (FRI) scores were assessed at post-crash and at 12 months.

RESULTS

At 12 months, mean scores in six and five of the SF-36 domains were significantly lower among participants who claimed compensation versus those who chose not to claim or were ineligible, respectively. Differences in mean SF-36 scores ranged from 3.0 ('general health perception') to 8.0 units ('role limitations due to physical problems'). Participants who claimed compensation had 6.3- and 4.6-units lower SF-36 physical component score compared to those who were ineligible (p=0.001) or chose not to claim (p=0.01), respectively. Participants who claimed compensation reported a worse HADS-depression score of 6.46 versus 4.97 and 4.69 observed in those who were ineligible (p=0.04) or did not claim (p=0.01). Claimants had worse FRI scores compared to non-claimants (p=0.01) and those who were ineligible (p=0.01). The early intervention did not improve health outcomes, 12 months after injury.

CONCLUSIONS

Claiming compensation was associated with a worse health status for people with soft tissue injuries caused by road traffic crashes. The health status in people claiming compensation was not altered by an early intervention programme.

A Clinician's Role in the Management of Soft Tissue Injuries of the Face: A Clinical Paper

INTRODUCTION

Injuries of the facial soft tissues may be due to road traffic accidents, industrial injuries, domestic and interpersonal violence, dog bites, human bites, war injuries etc. They may be described depending on the depth of involvement of the soft tissue and/or region since it gives the clinician the method of treatment. The soft tissue injuries must take into the underlying skeletal injury into account since these injuries if carelessly handled they leave deformed scarring in the most precious and beautiful part of the body.

MATERIALS AND METHODS

Various patients reporting to the department of Oral and Maxillofacial Surgery, Narayana Dental College and hospital, Nellore were included in the study. Injuries in the various aspects of face at various anatomical areas has been presented with the mode of management.

CONCLUSION

The maxillofacial surgeon while attending these cases should avoid the need for revision by having a thorough knowledge of the anatomy, physiology of the soft tissues and treat them accordingly after following good clinical and radiological examination.

An early intervention programme had no detectable influence on the health status of people with musculoskeletal injuries following road traffic crashes: comparative study

OBJECTIVE

To compare the health status of people with minor injuries from road traffic crashes that are exposed to an early, active intervention programme (intervention group) with those receiving usual care (control group) over a 12 month period.

DESIGN

Prospective comparative study using sequential cohorts.

SUBJECTS

People presenting to hospital emergency departments with mild to moderate musculoskeletal injuries following road traffic crashes.

MAIN OUTCOME MEASURES

Physical Component Score (PCS) and Mental Component Score (MCS) of the Short Form 36 (SF-36) health status measure; Hospital Anxiety and Depression Scale (HADS) and the Functional Rating Index (FRI) recorded immediately post-crash, at 6 months and at 12 months after injury.

RESULTS

There were 95 participants allocated to the control group and 98 allocated to the intervention group. Participants were enrolled at a mean of 9.3 days following the crash. There were no significant differences in baseline health measures between the groups. Apart from a small improvement in anxiety for the intervention group, there were no significant differences in health status between the groups. Twenty percent of participants in the intervention group received treatment from external healthcare providers that was inconsistent with the recommendations of the intervention programme.

CONCLUSIONS

The intervention programme failed to result in a clinically significant improvement in health outcomes compared with usual care. There is some evidence to suggest that the intervention had some psychological benefits, as evidenced by the small improvement in anxiety levels. Limited adherence, frequent use of co-interventions, or other factors (such as intervention content or intensity) may have reduced its effect.

Changes to the mechanical properties of the glenohumeral capsule during anterior dislocation

The glenohumeral joint is the most frequently dislocated major joint in the body, and instability due to permanent deformation of the glenohumeral capsule is a common pathology. The corresponding change in mechanical properties may have implications for the ideal location and extent of plication, which is a common clinical procedure used to repair the capsule. Therefore, the objective of this study was to quantify the mechanical properties of four regions of the glenohumeral capsule after anterior dislocation and compare the properties to the normal glenohumeral capsule. Six fresh-frozen cadaveric shoulders were dislocated in the anterior direction with the joint in the apprehension position using a robotic testing system. After dislocation, mechanical testing was performed on the injured glenohumeral capsule by loading the tissue samples in tension and shear. An inverse finite element optimization routine was used to simulate the experiments and obtain material coefficients for each tissue sample. Cauchy stress-stretch curves were then generated to represent the mechanical response of each tissue sample to theoretical loading conditions. Based on several comparisons (average of the material coefficients, average stress-stretch curve for each region, and coefficients representing the average curves) between the normal and injured tissue samples, the mechanical properties of the injured tissue samples from multiple regions were found to be lower than those of the normal tissue in tension but not in shear. This finding indicates that anterior dislocation primarily affects the tensile behavior of the glenohumeral capsule rather than the shear behavior, and this phenomenon could be caused by plastic deformation of the matrix, permanent collagen fiber rotation, and/or collagen fiber failure. These results suggest that plication and suturing may not be sufficient to return stability to the shoulder after dislocation in all individuals. Thus, surgeons may need to perform a procedure that reinforces or stiffens the tissue itself, such as reconstruction or augmentation, to improve repair procedures.
