Ultrasonography in the assessment of hand injuries in children: A systematic review.

Despite the frequency of paediatric hand injuries, recommendations for diagnostic investigations are limited due to paucity of published guidelines. This has led to inappropriate diagnoses and therefore inappropriate management. Ultrasonography is a portable, non-ionising imaging modality that allows rapid real-time evaluation of anatomical structures at a low cost and without sedation. In the adult population, ultrasonography has already been shown to improve accuracy in hand injury diagnoses. However, in the paediatric population, only one narrative review focuses on the application of ultrasonography to diagnose hand injury. A systematic search using PubMed, Google Scholar, EMBASE, Scopus, Cochrane database of systematic reviews and University Library of York, Keele, Edinburgh and King's College London was conducted to assess literature surrounding use of ultrasonography as a diagnostic tool for paediatric hand injuries. The literature search yielded 11,860 articles and 21 studies were identified with a total of 30 patients. Ultrasonography was observed to be an accurate tool for diagnosing bone, tendon, ligament and nerve injuries in children. The results of our study suggest that ultrasonography should be considered as an early diagnostic step for paediatric hand injuries.

Wrist Arthroscopy in Juvenile Idiopathic Arthritis: A Review of Current Literature and Future Implications.

Introduction Juvenile Idiopathic Arthritis (JIA) is the most common rheumatological condition in children and frequently affects the wrist. The roles for wrist arthroscopy and arthroscopic synovectomy (AS) in JIA are unclear. Our aim was to find the current evidence supporting its use. Methods Systematic literature review of relevant publications from 1990 to present in the Cochrane Library, Clinical Knowledge Summaries, DynaMed, PEMSoft, NICE Guidance, MEDLINE, EMBASE, and PubMed. Results We found no publications detailing the use of arthroscopy or AS specifically in patients with JIA involving the wrist. There is evidence that AS reduces pain, improves function, and induces remission in patients with rheumatoid arthritis resistant to medical management. Discussion and Conclusion Although there is paucity in evidence for the use of AS in the wrists of patients with JIA, studies suggest it to be safe and effective, and could be applied to patients with refractive JIA. It is possible that early identification of patients suffering from JIA with extensive joint destruction and little symptoms could benefit from AS, delaying joint destruction and preserving function.

[DASH data of non-clinical versus clinical groups of persons--a comparative study of T-norms for clinical use]. / DASH-Daten nicht-klinischer versus klinischer Personengruppen--eine Vergleichsstudie mit T-Normen für die klinische Praxis.

AIM: The aim of this study was to determine a) data for the disabilities of arm, shoulder and hand (DASH) score of a non-clinical group as well as to establish b) a comparison of DASH data between different groups of people. PATIENTS AND METHODS: After collection of 716 DASH questionnaires from healthy, working individuals (non-clinical sample) and 795 questionnaires from patients with injuries and conditions of the upper extremity (clinical sample), the data were assessed according to age, gender, manually or non-manually working into DASH total, DASH activity, DASH impairment, DASH music/sport and DASH work scores. In order to establish a comparability, these data were transformed using T-norms. RESULTS: Median DASH data of the non-clinical sample showed a functional impairment, since they deviated from 0. Men, aged 50-65, who were working manually showed the highest DASH score. Age did not have a significant effect on the DASH score of the clinical sample. The median overall DASH score of the clinical sample was higher than the scores seen with the non-clinical sample. CONCLUSION: Using T-norms a reference framework has been established for DASH scores, thus making it possible to interpret and compare individual scores between patients.

Evaluating the effectiveness of a patient-oriented hand rehabilitation programme.

This study evaluated the effectiveness of a patient-oriented, hand rehabilitation programme compared to a standard programme regarding functional outcomes, return to work, patient satisfaction and costs. Patients were recruited in two consecutive cohorts. One cohort received the standard treatment programme (n = 75) and the other a programme based on principles of patient orientation (n = 75). Data were collected at the beginning and end of rehabilitation and 6 months after discharge. Clinical variables included range of motion, grip and pinch strength. Self-reported measures included pain, upper extremity functioning, health status, satisfaction and job situation. Analysis of variance for repeated measurements was used to calculate the main effects. The patient-oriented group showed more favourable results with respect to DASH scores (P <.05), pain (P <.001) and patient satisfaction (P <.0001). More patients returned to their former jobs and time off sick was reduced. We concluded that the patient-oriented approach was more effective and cost-saving.

The clinical anatomy of the triangle of Petit.

INTRODUCTION: Hernias through the triangle of Petit (TP) are uncommon. The anatomy of the TP is known to be variable, yet quantitative data are scant. MATERIALS AND METHODS: The triangle was observed in 80 adult cadavers and its dimensions and surface area were measured. RESULTS: On the basis of surface area we classified the triangles into four types. Type I or small TP, with a surface area of <8 cm2, accounted for 43.7% of our specimens. Type II (26.2%) were intermediate in size, with a surface areas of 8-12 cm2. Type III (12.5%) were large triangles with surface areas >12 cm2. Finally, Type IV (17.5%) were not triangles. In these, the latissimus dorsi was covered by the external abdominal oblique muscle. CONCLUSIONS: We hope these data will help prediction of which patients are at greater risk of herniation through the TP.

[Ulnar nerve lesions after osteosynthesis of a supercondylar humerus fracture during childhood. Indications for revision]. / Ulnarisläsion nach Osteosynthese der suprakondylären Humerusfraktur im Kindesalter. Indikationen zur Revision.

Since 1948, closed reduction and osteosynthesis for supracondylar humeral fractures using two K-wires from the medial and lateral side has been performed on a regular basis. Although this procedure is used routinely, many authors have described paralysis of the ulnar nerve after blindly inserting the medial K-wire. Only very few publications describe the treatment options after iatrogenic paralysis of this nerve. The patients described showed progressive paralysis of the ulnar nerve after K-wire osteosynthesis. Intraoperatively, all patients showed scarring but intact continuity. After surgical revision and neurolysis, all four patients showed complete restitution after 1 year. If patients show progressive paralysis of the ulnar nerve early operative revision after 3 months should be performed.

[The balloon dissector in expander treatment: A ten-year experience in plastic and reconstructive surgery]. / Der Einsatz des Ballondissektors in der Expanderchirurgie: Zehn Jahre Erfahrung in der plastischen und rekonstruktiven Chirurgie.

BACKGROUND: The use of the balloon dissector ("space maker") for the implantation of soft tissue expanders is illustrated and technical aspects and advantages are compared to the conventional method. PATIENTS AND METHODS: Over a 10-year period a group of 90 patients with evaluation records (m = 34, f = 56) was analysed retrospectively. The mean age was 23 years (range: 5 to 62 years). Overall, 164 expanders were implanted and in 73 cases (44.5%) a balloon dissector was used. RESULTS: The mean intraoperative expander filling was increased up to 27% of the volume of the tissue expander after using the balloon dissector; in contrast it was 15% after conventional dissection. The mean duration of expansion was decreased by 9.8% after space maker dissection. CONCLUSION: The use of the space maker is a scar-sparing technique. Time of operation and overall duration of expansion are reduced. Patient comfort is clearly improved. The negligible costs of a space maker are compensated by the cost reduction due to shorter operating time, fewer outpatient contacts and a low complication rate. The indications for the use of balloon dissectors are the expansion of skin (scar correction after burns, trauma, tumour), breast reconstruction and augmentation, and the prefabrication and rapid intraoperative expansion of musculocutaneous flaps.

Extremity salvage with a free musculocutaneous latissimus dorsi flap and free tendon transfer after resection of a large congenital fibro sarcoma in a 15-week-old infant. A case report.

A case of complex microsurgical reconstruction of the dorsum of the foot, including tendon transfer following tumor resection, in a 15-week-old male infant is presented. After birth, a 5.5 x 4 cm large tumor was observed on the dorsum of the right foot. Biopsy showed a congenital malignant fibro sarcoma. After initial chemotherapy a radical excision of the tumor at the age of 14 weeks was followed. To cover the defect a musculocutaneous latissimus dorsi flap was taken, the cutaneous part being large enough to cover the defect. Extensor tendons were reconstructed with free tendon transplants. Amputation is usually indicated in these cases. To the best of our knowledge, microsurgical reconstruction in infants at this age with congenital malignant tumors has not yet been reported. The case shows that Plastic surgery can play an important role in pediatric oncology and should routinely be integrated into the multi-modal treatment concepts.

[Survival strategy of burn centers in the context of the German DRG system: reimbursement]. / Uberlebensstrategie der Schwerbrandverletztenzentren im Kontext der Y-DRG: Budgetsicherung.

BACKGROUND: The system of German diagnosis-related groups (G-DRG) has undergone modifications for burn cases (Y-DRG) since 2003. The DRG catalog includes two of seven Y-DRGs without a case weight. METHODS: The BG Trauma Center in Ludwigshafen could demonstrate that the cost of burn care treatment could not be reimbursed through Y-DRGs in 2004. RESULTS: By being accredited as a so-called "individual hospital-based unit" for burn care (Besondere Einrichtung), it was possible to agree to an "all-inclusive" contract. The daily rate is reimbursed with 2792 Euros/day. The reimbursement of the treatment of burn patients is thus cost covering. CONCLUSION: In summary the budget for 2006 should be calculated by an individualized hospital rate for all Y-DRGs, especially as it was shown that the additional payments (Zusatzentgelte) for selected therapies did not cover the costs of special treatments in burn care in 2005 and 2006. The problem has been recognized and published internationally. The special and cost-intensive treatment of burn patients is difficult to calculate in a system of diagnosis-related groups due to the low number of cases.

[Does the disability of shoulder, arm and hand questionnaire (DASH) replace grip strength and range of motion in outcome-evaluation?]. / Ersetzt der Disability of Arm, Shoulder and Hand Questionnaire (DASH-Fragebogen) die Erfassung von Bewegungsausmass und Kraft bei der Bewertung von Ergebnissen?

Scoring systems currently used to evaluate functional disabilities in upper extremity conditions frequently combine so-called "objective" parameters such as grip strength and range of motion with "subjective" parameters such as pain. Since its introduction, the Disabilities of Arm, Shoulder and Hand Questionnaire has proven useful in the pre- and postoperative evaluation of functional limitations of the upper extremity. This study examines the relationship between DASH scores, the so-called "objective" parameters of grip strength and range of motion and those of "mixed scores" such as Krimmer and Cooney Scores. Based on the data of six diagnostic groups, Spearman's correlation coefficients were calculated. There was no correlation between DASH scores and range of motion, however, some of the diagnostic groups showed a moderate correlation between DASH scores and grip strength. Both the Krimmer and Cooney scores showed a significant correlation with the DASH scores, indicating that these "mixed-scores" can be replaced by the DASH. Since it has been shown that grip strength and range of motion do not capture patients' functional limitations adequately, their continued use in the evaluation of upper extremity conditions should be the topic of further discussion.

Disabilities of the arm, shoulder and hand (DASH) questionnaire: Determining functional activity profiles in patients with upper extremity disorders.

The Disability of Arm, Shoulder and Hand (DASH) questionnaire is a standardized measure which captures the patients' own perspective of their upper extremity health status. Based on the scores of the DASH modules: symptoms, function and sport, this follow-up study of 590 hand-injured subjects from 11 diagnostic groups evaluated impairments and disabilities perceived 2 to 5 years postoperatively. Secondly, we explored the relationships between the diagnostic groups at the individual DASH item level. Exploratory testing of statistical significance showed that the DASH modules differentiated well among the groups (ANOVA P-value 0.001) and further differences existed at the item level, so that functional activity problem profiles could be developed for each diagnostic group. Our findings confirm that the DASH is a useful instrument for outcome evaluation. Moreover, in view of the continuing challenge to provide comprehensive care which meets patients' needs in the shortest space of time, we consider that DASH has potential in the development of patient-centred treatment programmes which are tailored to the individual patients' requirements and have relevance to their daily activities.

[The role of plastic and reconstructive surgery within an interdisciplinary treatment concept for diabetic ulcers of the foot]. / Stellenwert der Plastischen Chirurgie im interdisziplinären Therapiekonzept diabetischer Ulzera am Fuss.

BACKGROUND AND OBJECTIVE: Diabetes mellitus and its sequelae such as the "diabetic foot" are increasing in incidence and pose a challenging medical and financial problem. Interdisciplinary teams have been formed to prevent and treat these problems, consisting of diabetic nurses and physicians, nutritionists, podiatrists, specialist shoemakers, general, orthopaedic and vascular surgeons. However, hardly mentioned in the literature are the surgical options offered by plastic and reconstructive surgeons. The aim of this study was to analyse the outcome of plastic surgical treatment for soft tissue defect coverage of the diabetic foot ulcer and to define the role of plastic and reconstructive surgery within an interdisciplinary treatment concept. PATIENTS AND METHODS: In a retrospective cohort study the charts of 38 diabetic patients (female n = 14/male n = 24) with an average age of 68.6 years and with 45 defects on the foot or ankle were analysed regarding the patient profile, defect etiology and size, operative procedures, complications and outcome results. RESULTS: Defect coverage was performed using 20 split skin grafts, 19 local flaps and 6 free flaps as well as 27 amputations. At the time of discharge 25 of 45 defects were closed (56 %), 15 patients had an amputation and in 3 cases a small defect remained. The success rate of defect coverage decreased with increasing comorbidity. Whereas 71 % of the defects were covered in ASA stage 2 patients, only 50 % of the defects could be covered in ASA stage 3 patients and only 33 % in ASA stage 4 patients. CONCLUSIONS: Despite a high complication rate, plastic surgical techniques in many cases prevented an amputation in this negatively preselected patient group. These results provide justification for plastic and reconstructive surgery being in any case part of an interdisciplinary treatment approach of the diabetic ulcer.

[The "Shoulder, Arms and Hand Disability Questionnaire" as a scale for identification of the diagnosis-specific activity profile]. / Der "Disability of shoulder, arms and hand"-Fragebogen als Instrument zur Identifikation diagnosespezifischer Aktivitätsprofile.

Functional disabilities of the upper extremities have a considerable social and economic impact so that interest was aroused in developing a valid and reliable instrument suitable for international use. The Disabilities of the Arm, Shoulder, and Hand questionnaire is a self-report measure recording functional limitations in the upper extremity. A German version is now available in German-speaking countries. Previous studies have been concerned with the evaluation of DASH scores. Based on the data of four diagnostic groups, this study explores DASH's ability to identify diagnosis-specific limitations at the item level. The data were pooled and examined with regard to significant differences within the groups. Diagnosis-specific limitations could be identified within all groups, indicating that DASH is capable of expressing diagnostic entities as well as summed scores. Consideration of the individual profiles opens the possibility of using DASH as a prognostic tool to anticipate functional problems arising during rehabilitation following surgical interventions.

Dynamic splinting after extensor tendon repair in zones V to VII.

This retrospective study evaluates a dynamic active motion protocol for extensor tendon repairs in zones V to VII. Fifty-eight patients with 87 extensor tendon injuries were examined. Using Geldmacher's and Kleinert and Verdan's evaluation systems, the results were graded as "excellent" and "good" in more than 94%, and as "satisfactory" in the remainder. The need for secondary tenolysis was low (6%), and no other surgical complication occurred.

Clinical practice of glycerol preserved allograft skin coverage.

This retrospective study examines the use and advantages/disadvantages of glycerol preserved human allograft skin in our burn care facility between February 1997 and December 1999. Three hundred and twenty patients were included into the study, 85 of whom were treated with human cadaver skin. The usage of allograft slightly increased the number of operative procedures per percent of the total body surface area burn. There were no adverse effects noted from the use of allograft. The group of patients with allograft use had a significantly larger burn size, ABSI score and length of ICU stay. Demographically the groups were comparable. The considerably easier handling and storage of glycerol preserved allograft skin make it preferable to cryopreserved allograft skin in all indications where it is used as a temporary wound closure. We recommend the usage of cryopreserved skin in cases where the integration of a dermal component as a permanent part of wound closure is desired.

Sequential microsurgical flap reconstruction following purpura fulminans during infancy and childhood.

Purpura fulminans is a potentially lethal complication of meningococcal septicemia, characterized by progressive hemorrhagic skin lesions, which can result in extensive necrosis and mummification of all the extremities. With improving survival rates in infancy and childhood, plastic surgeons are challenged more often to provide sufficient and stable soft-tissue coverage. Usually, conservative methods, such as skin grafting or amputation, are favored by many pediatric surgeons, since further specialized departments and training are not required. Often secondary reconstructive procedures to improve soft-tissue coverage have to be performed to achieve proper prosthetic fitting. Microsurgical techniques are used only in selected cases, after failure of other procedures for defect coverage. In two cases of post-acute purpura fulminans, two free flaps and three microsurgically dissected flaps were used as primary measures for defect coverage and preservation of stump length. Despite the presence of vasculitis, all flaps survived. In a third case, secondary reconstructive measures had to be performed 1 year after purpura fulminans due to insufficient soft-tissue coverage after lower leg amputation. This patient also had contractures on both hands and no grip function after complete finger loss. Several microsurgical procedures were performed to improve grip function and soft-tissue coverage. The primary use of microsurgical techniques prevents lengthy secondary reconstructive measures.
