[Retrospective Long-Term Results After Dellon's Nerve Decompression In The Lower Leg For Polyneuropathy]. / Retrospektive Langzeitergebnisse nach einer Nervendekompression nach Dellon am Unterschenkel bei Polyneuropathie.

BACKGROUND: Patients affected by polyneuropathy often report pain, paraesthesia and numbness and are at risk of having an increased propensity to fall with the corresponding complications. In case of persistent symptoms after all conservative and medical treatment options have been exhausted, a nerve decompression in the lower leg as described by Dellon can lead to an improvement of the discomfort for many patients. This article presents our long-term results with Dellon's operation. METHODS: In this retrospective study, we included 33 patients with diabetic or idiopathic polyneuropathy in whom we performed Dellon's nerve decompression in the lower leg in the years 2011-2013. In 29 out of the 33 patients, we investigated the level of pain (according to the numeric rating scale NRS 0-10), paraesthesia, numbness, Hoffman-Tinel sign, and Semmes-Weinstein monofilaments three months postoperatively. 88 months postoperatively (range 78-111 months), we were able to contact 20 of the 33 patients with a questionnaire asking about their present pain level (NRS 0-10), satisfaction with the postoperative result (NRS 0-10, 0=most satisfied, 10=not satisfied at all) and whether the patients would recommend the surgical procedure to their friends or family. RESULTS: 1. Significant pain reduction three months postoperatively, NRS 4.5 to 2.2, (p=0.000). 2. Significant reduction of paraesthesia three months postoperatively from 84.8 to 24.2% (p=0.000) 3. Significant reduction of numbness three months postoperatively from 97% to 39% (p=0.000). 4. Significant improvement of sensitivity three months postoperatively from 91% no sensitivity to 28% no sensitivity (p=0.000). 5. Significant improvement of Hoffmann-Tinel sign three months postoperatively from 76% to 13% (p=0.000). 88 months postoperatively, we saw a significant pain reduction from an average preoperative pain level of NRS 4.5 to a postoperative pain level of 2.7 (p=0.048). 88 months postoperatively, 65% of the patients would recommend the surgical procedure to their family and friends, and patient satisfaction was high (NRS 3,4). CONCLUSION: Our long-term results show that Dellon's nerve decompression in the lower extremities leads to a marked, lasting pain reduction and a functional improvement.

Nerve Decompression in the Lower Leg Results in an Improvement in Symptoms in Patients With Both Diabetic and Idiopathic Polyneuropathy.

BACKGROUND: Patients suffering from polyneuropathy often complain of pain, tingling, and numbness sensations, as well as an increased risk of falling with the corresponding subsequent complications. If symptoms persist after conservative treatment options have been exhausted, nerve decompression in the lower extremity, as described by Dellon, can bring about an improvement in symptoms in many patients. Dellon originally reported that this surgery led to very successful outcomes in patients with diabetic polyneuropathy. In this study, we compare our postsurgical results in patients with diabetic versus idiopathic polyneuropathy. METHODS: Thirty-three patients with idiopathic or diabetic polyneuropathy who had undergone Dellon nerve decompression in the lower extremity between 2011 and 2013 were included in the retrospective study. Pain (numeric rating scale [NRS] 0-10; 0, no pain; 10, worst imaginable pain), tingling, numbness, Hoffmann-Tinel sign, and Semes-Weinstein monofilament were assessed in 20 patients with diabetic polyneuropathy and in 13 patients with idiopathic polyneuropathy. RESULTS: Three months after surgery, a significant reduction in pain was evident in patients with diabetic polyneuropathy, from a preoperative level of NRS 4.9 (minimum, 0; maximum, 10) to 2 (minimum, 0; maximum, 8; P = 0.005). Ninety percent of patients complained of tingling ( P = 0.000) before surgery and 18% after surgery, whereas 100% complained of numbness before surgery and 41% ( P = 0.000) after surgery. One hundred percent of patients had no measurable surface sensitivity before surgery (measured with the Semes-Weinstein monofilament), whereas 3 months after surgery, only 24% of patients still had no measurable surface sensitivity ( P = 0.000). A positive Hoffmann-Tinel sign was recorded in 85% of patients before surgery and only in 11% 3 months after surgery ( P = 0.000). In the case of patients with idiopathic polyneuropathy, a reduction in pain was evident 3 months after surgery, from a preoperative level of NRS 3.9 (minimum, 0; maximum, 9) to 2.2 (minimum, 0; maximum, 9; P = 0.058). Seventy-seven percent of patients complained of tingling before surgery and 42% after surgery ( P = 0.111), whereas 92% complained of numbness before surgery and 50% after surgery ( P = 0.030). Seventy-seven percent of patients had no measurable surface sensitivity before surgery (measured with the Semes-Weinstein monofilament), whereas 3 months after surgery, only 33% of patients still had no measurable surface sensitivity ( P = 0.047). A positive Hoffmann-Tinel sign was recorded in 62% of patients before surgery and only in 17% 3 months after surgery ( P = 0.041). CONCLUSIONS: Not only patients with diabetic polyneuropathy but also those with idiopathic polyneuropathy benefit from Dellon nerve decompression surgery in the lower extremities.

Active Heating following Cryolipolysis Reduces Efficacy and Side Effects: A Randomized Split-Body Trial.

BACKGROUND: Cryolipolysis-a popular noninvasive technique for body contouring-has fewer side effects compared with liposuction; however, its effectiveness in terms of reducing local adipose tissue is also lower. This study is, to the authors' knowledge, the first prospective, controlled, investigator-blinded split-body trial to evaluate whether postcryolipolytic heating can increase the efficacy. METHODS: Twenty-five subjects were treated with one session of cryolipolysis on the lower abdomen and a subsequent heating with a mud pack of a randomized side of the treated region (left or right). Epidemiologic, temperature, edema, erythema, hypesthesia, and pain level data were obtained. Photographs, fat layer thickness (on ultrasound, caliper, and abdominal girth), satisfaction, and side effects were documented over a follow-up period of 12 weeks. RESULTS: The side effects-edema, erythema, and hypesthesia-faded almost completely with heating, whereas they remained on the nonheated site. However, the mean sonographic reduction of local adipose tissue after 12 weeks was significantly lower on the heated sites than on the control sites (9.6% versus 14.1%; P = 0.0003). The overall satisfaction was high (9.2 of 10 points), even though only 44% of participants had a subjective recognition of fat loss without difference between the sites. CONCLUSIONS: Active heating following cryolipolysis increases bodily well-being by reducing common side effects, but it reduces the effectiveness of cryolipolysis significantly and should therefore be avoided. Further improvements are necessary to enhance the efficacy of cryolipolysis. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, I.

Autologous Fat Transfer for Thumb Carpometacarpal Joint Osteoarthritis: Long Term Results. / Eigenfettinjektion bei Rhizarthrose: 5 Jahresergebnisse bei 42 Patienten.

BACKGROUND: Initial results after autologous fat transfer for treatment of thumb carpometacarpal joint osteoarthritis have been promising. But long-term results have not yet been available. METHODS: In a prospective study, 42 patients with thumb carpometacarpal joint osteoarthritis were observed for a mean time of 5 years after autologous fat transfer. Manual liposuction and centrifugation were performed. Pain rating according to numerous analogue pain scale; objective force of pinch grip and fist closure; and Disabilities of the Arm, Shoulder, and Hand questionnaire score (DASH score) before and after treatment were analysed. RESULTS: The average pain preoperatively was 8.0 ± 1.6 and 4.0 ± 3.0 after 5 years overall. Force and pinch force of the treated hand improved from 71% and 60% preoperative in comparison to the non-treated hand to 100% and 96%, respectively, 5 years after fat transplantation. There were similar improvements for the parameters strength and DASH score. All improvements were statistically significant. No serious adverse events were observed. CONCLUSIONS: Autologous fat transplantation is a real alternative to trapeziectomy even in the long term in basal joint osteoarthritis of the thumb. The low invasiveness of the procedure and early recovery of patients compared with classical procedures such as trapeziectomy, and the superior long-term results compared with classical injection therapy, make this approach feasible as a first-line therapy in basal joint osteoarthritis of the thumb as it offers stable results and warrants a high patient satisfaction rate.

Lipofilling in Osteoarthritis of the Finger Joints: Initial Prospective Long-Term Results.

BACKGROUND: There is considerable interest in the possibility of offering an alternative and less invasive method of treatment for osteoarthritis that will preserve the joint. This article presents for the first time the long-term results of a prospective study following autologous fat transfer to arthritic finger joints. METHODS: The authors report on 28 finger joints with osteoarthritis that they treated by injecting fatty tissue into the joints. The degree of pain, force of pinch grip, and fist closure were assessed and hand function was determined using the German version of the Disabilities of the Arm, Shoulder and Hand questionnaire. RESULTS: The average follow-up period during the study was 44 months. The median force of pinch grip rose highly significantly from 2.00 kg (range, 0.00 to 11.00 kg) to 4.30 kg (range, 2.00 to 12.00 kg) (p < 0.001). The median force of fist closure rose from 15.00 kg (range, 2.00 to 44.00 kg) to 18.00 kg (range, 3.78 to 42.00 kg) (p = 0.082). The median Disabilities of the Arm, Shoulder and Hand value improved nonsignificantly from 50 (range, 3 to 72) to 25 (range, 0 to 85) (p = 0.129). The median level of pain experienced showed a highly significant improvement from 6.0 (range, 1.0 to 10.0) to 0.5 (range, 0.0 to 6.5) (p < 0.001). CONCLUSIONS: Even over a long-term study period, the transfer of fatty tissue to arthritic finger joints has shown itself to be a minimally invasive, safe and promising alternative treatment to conventional surgical procedures that offers significant improvements in terms of osteoarthritis symptoms. Because this method preserves the joint, conventional resection surgery still remains a later option. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

[A prospective Study about medium-term Results after autologous Fat Transplantation into arthritic CMC-I-joints]. / Prospektive Untersuchung der mittelfristigen Ergebnisse nach autologer Fetttransplantation in arthrotische Sattelgelenke.

PURPOSE: Prospective study to evaluate the midterm results after transfer of autologous fat into osteoarthritic CMC-I-joints. PATIENTS AND METHODS: 23 out of 27 patients (22 females and 5 men) with an average age of 59,8 (49-83) years with osteoarthritis of the CMC I joint were treated with a fat transfer into the damaged joints. The follow-up was 45,3 (39,3-50,9) months. 4 patients were excluded from the follow-up because of a resection arthroplasty in the meantime. Grip strength and pinch strength, DASH questionnaires and pain (VAS) were analysed. RESULTS: The average pinch strength increased from preoperatively 3,7 kg to 5,1 kg postoperatively (p = .052). The average grip strength increased minimally from preoperatively 22,2 kg to 22,8 kg at follow-up (p = .506). The average DASH score improved significantly from preoperatively 50,8 to 29,6 postoperatively (p = 0,000). The average pain level decreased significantly from preoperatively 5,9 to 1,9 at follow up (p = .000). Patients with an advanced osteoarthritis of the CMC-I-joint had similar results as patients with a minor osteoarthritis. CONCLUSION: The autologous fat transfer into the osteoarthritic CMC-I-joint showed in midterm follow-up good to very good clinical results regarding pinch strength, pain and DASH score. It is a safe minimal invasive promising alternative to accepted surgical therapies in the treatment of osteoarthritis of the CMC-I-joint.

[The effects of standardised cold and compression therapy on swelling, pain and functional outcome after division of the transverse carpal ligament in carpal tunnel syndrome]. / Der Einfluss von standardisierter Kälte- und Kompressionstherapie auf Schwellung, Schmerzhaftigkeit und das funktionelle Ergebnis nach Spaltung des Retinaculum flexorum bei Karpaltunnelsyndrom.

OBJECTIVE: This prospective, randomised study examines the effect of standardised cold compression therapy on swelling, pain and functional outcome after division of the transverse carpal ligament in carpal tunnel syndrome in comparison to cooling alone. PATIENTS AND METHODS: Fifty patients for division of the transverse carpal ligament were randomised into two groups. In group 1, postoperative conventional cooling therapy was performed. Group 2 was given standardised cooling and compression therapy with the Cryo/Cuff™-system (3 × 10 min twice daily). Follow-up examinations were performed on days 1, 8 and 21 after the operation. One patient in group 1 and 3 patients in group 2 could not be followed up. Test parameters were pain, swelling, mobility, strength, and the DASH and MHQ score. RESULTS: There were no significant differences between the two groups at any time point. CONCLUSION: In this study, no advantage could be demonstrated for standardised cooling and compression therapy with the Cryo/Cuff™-system in comparison with conventional cooling after division of the transverse carpal ligament.

Anatomical study of the human sole of the foot by 4-dimensional CT angiographic vascular imaging - its suitability as composite tissue allotransplantation graft for foot defects.

BACKGROUND: The reconstruction of the weight-bearing sole is a challenge for every plastic surgeon. Composite tissue allotransplantation (CTA) of the sole of the foot may be a good therapeutic option for patients with large defects in the weight bearing area of the foot. As part of the preparation for a CTA of the sole, we sought to prepare for technical aspects related to preparation and perfusion of the human sole, on the basis of a systematic anatomical study, in combination with 4-dimensional computed tomography-angiography. MATERIAL/METHODS: An anatomical study was performed on 10 cadaver feet. CT images of the feet were prepared in a GE light speed 16-line computed tomogram (CT) before and after the preparation of the sole. After each CT scan, contrast medium was injected in 0.2 ml steps over the posterior tibial artery. RESULTS: Good images of the vessels of the sole from all 10 feet were achieved after recovery of the posterior tibial artery with accessory veins, the tibial nerve, the medial calcaneal branches from the posterior tibial artery, the abductor hallucis, digitorum brevis, abductor digiti minimi, lumbricales and interossea plantares muscles, even after preparation of the soles. CONCLUSIONS: With this systematic anatomical preparation of the soles of the feet from human cadaver preparations, in combination with 4-dimensional CT angiography, we were able to demonstrate the technical feasibility of sole transplantation. CT angiography should be performed preoperatively, in order to demonstrate that the vessels are patent as pedicle for the sole of the foot.

Variable disease progression after successful stem cell transplantation: prospective follow-up investigations in eight patients with Hurler syndrome.

We report the results of a prospective, standardized follow-up programme of eight children (median age at SCT 1.2 yr) with mucopolysaccharidosis (MPS1H, M. Hurler) transplanted using a fludarabine-based SCT. SCT resulted in stable engraftment without transplant-related mortality. All patients are alive, engrafted and in ambulatory care. During follow-up (median five yr, 1.9-8 yr), six of eight showed developmental delay (two severe, two mild/no), all eight had spinal deformities and one received hip surgery for acetabular dysplasia. Hand surgery for carpal tunnel release and trigger digits was required in five of the patients. The cranio-cervical junction was narrowed in four patients, one child having already received surgery. CC was present in all patients prior to SCT. It remained unchanged in seven and regressed in one child. Severe cardiac dysfunction was present in two of the eight children before SCT. Cardiac pump function was normal in six patients and ameliorated in two, while valve abnormalities could be detected in six patients. Currently, transplantation seems no longer the major obstacle for MPS1H patients, but the variable musculoskeletal disease progression after successful SCT remains a challenge. Patients with Hurler syndrome need specialized follow-up care because of their manifold health problems. The standardized follow-up presented here is a step to optimize care for MPS children and their families after SCT.

Is there an association between comorbidities and the outcome of microvascular free tissue transfer?

The aim of this study was to evaluate the relevant conditions for safe free flap transfers. The authors retrospectively studied the data from 150 patients who received free flaps at a single institution. Many parameters were analyzed to reveal if there was a correlation with respect to surgical or medical complications. Regarding safety of free tissue transfer, we found a worse prognosis in flaps where a revision of the microanastomosis had to be performed. Platelet count and leukocyte count had an impact on the prognosis. Patients older than 60 years did not have an increased rate of surgical complications. Apart from active osteomyelitis, the presence of comorbid conditions did not significantly impair the outcome of flap transfer, although smoking and diabetes correlated with minor surgical complications like wound breakdown or hematoma, respectively. Besides one case of lethal heart failure of an octogenarian patient, no severe medical complications occurred in this series of patients. Microvascular free tissue transfer is not significantly impaired by age and most comorbidities. Osteomyelitis as well as elevated leukocytes and lowered platelets may increase the complication rate and worsen the surgical prognosis. Smoking and diabetes might prolong the hospital course of the patients.

Composite tissue allotransplantation in Europe. Logistics and infrastructure of a centre.

BACKGROUND: Composite Tissue Allotransplantation (CTA) is a new medical field of growing importance. This paper focuses on the infrastructure and organisation of European CTA centres and discusses the differences between national health systems. MATERIAL/METHODS: Eight European centres (Valencia, Innsbruck, Munich, Lyon, Amiens, Creteil, Wroclaw, Monza) were sent with a specially-designed, standardized, 20-item questionnaire. RESULTS: Five of the eight centres returned our questionnaire: Munich, Innsbruck, Lyon, Amiens, Wroclaw. Since 1998, CTA has been performed at these centres. In both French centres and the Polish centre public funding is available in addition to the coverage provided by health insurers. In Munich the costs for a double upper-arm transplantation were Euro 150,000 with an additional Euro 50,000-70,000 per year. In Lyon the costs for a singular hand transplantation were Euro 70,000 per year and in Wroclaw (Poland) the costs for a hand or upper arm transplantation were Euro 20,000-30,000. As many as 17 different medical professions are involved in the CTA at the different centres. CONCLUSIONS: CTA is an innovative promising therapeutic tool that is based on the experiences of solid organ transplantation and profound microsurgical skills. Due to the complexity of the infrastructure, sourcing and the organisation CTA can only be successfully performed at specialized centres. A European network with an international European waiting list and a central coordination for CTA should be established. In order to advance CTA as an important tool in reconstructive surgery we must turn our attention to how the costs will be met, the legal environment for procurement of adequate donors and open ethical questions.

Reflectance confocal-laser-scanning microscopy in vivo assessments of cigarette-induced dynamic alterations of cutaneous microcirculation on histomorphological level.

OBJECTIVE: Until now, high resolution reflectance confocal-laser-scanning microscopy (CLSM) was used for observation of cutaneous morphology in vivo and in real time. We hypothesized that CLSM also allows observation of dynamic processes of cutaneous microcirculation. METHODS: Reflectance CLSM (Vivascope1500; Lucid, Rochester, NY) was performed in 24 young male habitual smokers (23 years, range: 19-26, body mass index 23.9 +/- 4.04) with relatively limited cigarette exposure (mean: 3.1 +/- 2.4 pack-years). Eight matched nonsmokers served as controls. The quantitative blood cell flow and the diameter of capillary loops were determined prior (baseline), during, as well as 5 and 10 min after smoking. RESULTS: Baseline value for blood cell flow was 55.50 +/- 2.33 cells/min, and decreased over 45% during smoking (30.43 +/- 3.76/min; P = 0.02). They were still 22% lower (43.33 +/- 2.45/min; P = 0.01) 5 min after smoking and exceeded baseline values 10 min after smoking by 13% (63.00 +/- 3.10/min; P > 0.05). The baseline values for capillary loop diameter (9.03 +/- 0.22 microm) decreased by 21% (7.18 +/- 0.28 microm; P = 0.03) during smoking, remained about 9% (8.23 +/- 0.18 microm; P = 0.01) lower 5 min after smoking and exceeded baseline values insignificantly by 4% (9.38 +/- 0.28 microm; P > 0.05) 10 min after smoking. There were no significant differences to the controls. CONCLUSION: Reflectance CLSM enables qualitative and quantitative observation of dynamic processes of cutaneous microcirculation on histomorphological level.

Influence of transendothelial mechanisms on microcirculation: consequences for reperfusion injury after free flap transfer. Previous, current, and future aspects.

The success of a free microvascular tissue transfer is based on a sufficient microanastomosis which meets the following requirements: a pedicle placed without kinking or twisting, good drainage, a well-defined recipient vessel, integrity of the endothelium, and duration of ischemia. The extent of skin and muscle necrosis increases significantly with increases in ischemia time. Reperfusion of ischemic tissue results in local and systemic damage associated with the release of oxygen free radicals, polymorphonuclear leucocytes, and such endothelial hormones as endothelin-1, EDRF (endothelial-derived relaxing factor), thromboxane, complement, and cytokines. Ischemia-reperfusion disrupts the delicate balance that maintains homeostasis in the microcirculation. This review discusses the clinical and therapeutic aspects of such injury, concentrating on perioperative management in free flap transfer. It points out the possible influence of endothelin-1 on vasospasm at the site of anastomosis, and emphasizes the importance of the endothelium as a highly dynamic network. Finally, future diagnostic and therapeutical aspects are discussed.
