Three-dimensional CT angiography for surgical planning in congenital hand malformations: a case series presentation.

J Hand Surg Eur Vol 2020 Dec 17;45(10):1017-1022. Epub 2020 Sep 17.

Department of Plastic, Reconstructive and Aesthetic Surgery, Medical University Innsbruck, Innsbruck, Austria.

Between January 2000 and December 2019, three-dimensional computer tomographic (CT) angiography was used in a total of 140 hands (116 patients, mean age 6.8 years) with congenital hand malformation to assess the vascular and bony structures. Analysis showed overall satisfactory three-dimensional CT images for operative planning, including detailed abnormal vascular patterns and bony malformations. Among the 116 patients, six patients with typical findings of a few malformations are reported in detail. Pitfalls in interpretation of the images and the use of three-dimensional CT angiography in surgical planning are discussed. We conclude that three-dimensional CT angiography is useful for preoperative planning of complex congenital hand malformations. IV.

Treatment of Severe Ulnar Instability of the MCP Joint Improves Function in LRTI Arthroplasty for Osteoarthritis of the Thumb CMC Joint.

J Wrist Surg 2020 Apr 31;9(2):105-115. Epub 2019 Dec 31.

Practice for Plastic and Hand Surgery, Murnau, Germany.

 Comorbidity in the metacarpophalangeal joint (MCPj) of the thumb, i.e., hyperextension or ulnar collateral instability, could affect the outcome of arthroplasty in the thumb carpometacarpal joint (CMCj).  In a retrospective study, we evaluated the effect of arthrodesis of the MCPj for thumbs with unstable MCPj and simultaneous ligament reconstruction tendon interposition (LRTI) arthroplasty for the CMCj in terms of strength, function, and patient satisfaction.  A total of 69 thumbs treated with a LRTI arthroplasty of the CMCj were included. In 14 of those cases, an arthrodesis of the MCPj was performed as well. In 12 thumbs, both procedures were done simultaneously; in one case MCPj arthrodesis followed LRTI arthroplasty, whereas one patient already had MCPj arthrodesis at time of LRTI arthroplasty. Those 14 thumbs were compared with the control group of 55 thumbs who had only undergone LRTI. At a mean follow-up of 4 to 5 years (mean 54 [10-124] months) postoperative assessments included range of motion (ROM) of the CMC, MCP, and interphalangeal (IP) joint of the thumb, as well as any instability of the MCPj. Pinch and grip strength were examined, also the visual analogue scale (VAS), patient satisfaction, QuickDASH, PRWE-Thumb, and the Kapandji's Opposition Score. Radiologically, proximalization of the first metacarpal bone was measured. Student's -test was used to determine significance,  < 0.05 was considered significant.  Additional arthrodesis of the MCPj provided no significant difference of function in thumbs that only had a hyperextension-instability. However, in thumbs with marked ulnar instability, stronger pinch-grip was obtained with arthrodesis, compared with only LRTI.  In patients with advanced painful thumb CMCj osteoarthritis, we recommend (simultaneous) arthrodesis of the MCPj, to allow a stable thumb grip if there is additional marked ulnar collateral ligament instability.  This is a Level III, retrospective comparative study.

STAT3/5 Inhibitors Suppress Proliferation in Bladder Cancer and Enhance Oncolytic Adenovirus Therapy.

Int J Mol Sci 2020 Feb 7;21(3). Epub 2020 Feb 7.

Department of Urology, Klinikum rechts der Isar, Technical University of Munich, 81675 Munich, Germany.

The JAK-STAT signalling pathway regulates cellular processes like cell division, cell death and immune regulation. Dysregulation has been identified in solid tumours and STAT3 activation is a marker for poor outcome. The aim of this study was to explore potential therapeutic strategies by targeting this pathway in bladder cancer (BC). High STAT3 expression was detected in 51.3% from 149 patient specimens with invasive bladder cancer by immunohistochemistry. Protein expression of JAK, STAT and downstream targets were confirmed in 10 cell lines. Effects of the JAK inhibitors Ruxolitinib and BSK-805, and STAT3/5 inhibitors Stattic, Nifuroxazide and SH-4-54 were analysed by cell viability assays, immunoblotting, apoptosis and cell cycle progression. Treatment with STAT3/5 but not JAK1/2 inhibitors reduced survival, levels of phosphorylated STAT3 and Cyclin-D1 and increased apoptosis. Tumour xenografts, using the chicken chorioallantoic membrane (CAM) model responded to Stattic monotherapy. Combination of Stattic with Cisplatin, Docetaxel, Gemcitabine, Paclitaxel and CDK4/6 inhibitors showed additive effects. The combination of Stattic with the oncolytic adenovirus XVir-N-31 increased viral replication and cell lysis. Our results provide evidence that inhibitors against STAT3/5 are promising as novel mono- and combination therapy in bladder cancer.

Skin grafting after paediatric palmar burns: an analysis of 82 patients.

J Hand Surg Eur Vol 2019 Dec 9;44(10):1031-1035. Epub 2019 May 9.

Department of Plastic, Reconstructive and Aesthetic Surgery, Innsbruck Medical University, Innsbruck, Austria.

Contact burn injuries to the palm are common in toddlers. We report a case series of 82 paediatric patients (age 7-48 months) with contact burn injury of the palm. We share our experience and outcomes of using plantar split-thickness skin grafts for resurfacing of the paediatric palm. We found that despite the excellent colour and texture match, split-thickness skin grafts from glabrous skin during growth are prone to motion-limiting scare contracture. From this series, we conclude that full-thickness skin grafts remain the reference standard of care in paediatric patients' hands. We recommend that children with burn scars should have regular check-up examinations until they are fully grown. IV.

[Therapy of Dupuytren's contracture with collagenase - Evidence-based Consensus Statement of Austrian Surgical Societies].

Handchir Mikrochir Plast Chir 2019 Aug 17;51(4):262-274. Epub 2018 Oct 17.

Univ.-Klinik für Plastische, Rekonstruktive und Ästhetische Chirurgie Innsbruck.

Dupuytren's contracture (DC) or Dupuytren's disease (DD) is a progressive fibro-proliferative disease of palmoplantar connective tissue, resulting in characteristic nodal and/or cord formation from collagen disposition. When the disease progresses, the thickening and shortening of the cords eventually leads the affected fingers to being pulled into flexion, which may be associated with marked disability, especially with bilateral disease. DD is relatively common in Europe, with the highest prevalence in Nordic countries. In Austria approx. 200 000 people are affected. The incidence increases with increasing age, with men being more often and earlier affected than women. The aetiology of DC is not completely clear, but it seems to be multifactorial; twin and familial studies confirm a genetic predisposition. The natural course of the disease can vary between relatively benign and massive progression and recurrence. In most cases, there is a fluctuating course. The DC is not curable; treatment methods range from minimally invasive to open surgical procedures. Collagenase Clostridium histolyticum (CCH) is a nonsurgical, enzymatic injection treatment for adult patients (≥ 18 years) with a palpable cord and has been approved in Europe since 2011. Clinical studies and practical experience of individual centres confirm the efficacy and safety of CCH treatment of DC. The present consensus statement was prepared under the auspices of the Austrian Society of Hand Surgery with the participation of the Austrian Society for Trauma Surgery, the Society of Orthopaedics and Orthopaedic Surgery as well as the Society for Plastic, Aesthetic and Reconstructive Surgery. On the basis of current literature and the experts' experience, it describes the various surgical procedures, with particular reference to collagenase treatment and provides guidance for their use. The statement is intended not only to illustrate the state of the art of current treatment, but also to support the achievement of uniform high quality standards in the treatment of DC in surgical centres and specialised medical practices throughout Austria.

[Concerning the Wrist-to-Forearm-Ratio of the Median nerve ultrasound is not a suitable method for assessing the success of a carpal tunnel release].

Handchir Mikrochir Plast Chir 2018 02 28;50(1):14-18. Epub 2018 Mar 28.

Universitätsklinik Innsbruck für Plastische Chirurgie.

Purpose: The primary aim of the study was to analyze whether there is and - if so - how far a correlation between the clinical findings after carpal tunnel release (CTR) for carpal tunnel syndrome (CTS) and the Wrist-to-Forearm-Ratio (WFR) of the median nerve in ultrasound to answer is question whether the WFR can be used in controlling the operative result.

Patients And Methods: In a prospective study the clinical, electrophysiological, and sonographic data of 40 patients with CTR for CTS were collected preoperative and 3 and 9 months postoperative. The data of 21 patients with 23 operated hands completing the study were analyzed. There were 5 men and 16 women with an average age of 58 years.

Results: Neither a correlation between the clinical findings postoperative and the WFR nor the electrophysiological findings postoperative was found.

Conclusion: Concerning the Wrist-to-Forearm-Ration of the Median nerve ultrasound is not a suitable method for assessing the success of a carpal tunnel release.

Arthroscopic Synovectomy Combined with Autologous Fat Grafting in Early Stages of CMC Osteoarthritis of the Thumb.

J Wrist Surg 2018 Apr 20;7(2):165-171. Epub 2017 Jul 20.

Practice for Plastic and Hand Surgery, Dr. Baur-Dr. Fromberg, Murnau, Germany.

 Minimal invasive treatments such as arthroscopic techniques may be adequate to restore the anatomy and functional integrity of the thumb CMC (carpometacarpal) joint. In this paper, we reported the interposition of autologous fat tissue in combination with arthroscopic synovectomy/debridement for early stage of the thumb CMC joint osteoarthritis.  Twelve patients with a mean age of 46 years with early radiological stages of thumb CMC joint osteoarthritis were included. Evaluation of outcome was measured prior and 3, 12, and 24 months after surgery including, Visual Analog Scale (VAS), QuickDASH, grip and pinch strength, range of motion (ROM), and patient satisfaction.  Pain at rest (or with load) was reduced from preoperative 4,7 (8,7) to 2 (5,9) at 3 to 6 months; 1,4 (4,3) at 12 months; and 0,75 (2,7) at 2 years after the surgery. Initial preoperative QuickDASH value of 52 points reduced to 33 (17-65) at 6 months, 23 (2-70) at 12 months, and 20 (11-29) at 24 months after the surgery. Grip strength and thumb pinch with respect to the contralateral untreated thumb was reduced in the first 12 months but recovered subsequently. ROM was equal to the contralateral thumb. Three patients suffered from tendinitis and required surgical treatment. One patient indicated prolonged pain symptoms. No infections were noted and no donor-site morbidity or side effects were detected.  Arthroscopic synovectomy combined with autologous fat graft is a reliable surgical option for early thumb CMC joint osteoarthritis and that effect continues for more than 24 months.

Practice for Plastic and Hand Surgery, James-Loeb-Str. 13, Murnau D-82418, Germany. Electronic address:

Partial wrist arthrodesis (PWA) is a well-known procedure for treating degenerative or posttraumatic wrist conditions. Four-corner fusion (4CF) is mostly used for scapholunate advanced collapse and scaphoid nonunion advanced collapse. The author performed 39 procedures, including 4CFs, 2-corner fusions, 3-corner fusions, scaphoid-capitate/scaphoid-capitate-lunate fusions, scaphoid-trapezium-trapezoid arthrodeses, and radioscapholunate arthroscopic PWAs (A-PWAs). There were 8 revision cases including 4 partial nonunions. All A-PWAs healed satisfactorily after revision surgery. This article discusses the surgical techniques and tips to avoid mistakes. The pros and cons for open versus arthroscopic techniques and for screws versus Kirschner wires are also discussed.

Memory Effect of the Median Nerve: Can Ultrasound Reliably Depict Carpal Tunnel Release Success?

Rofo 2017 Jan 19;189(1):57-62. Epub 2016 Sep 19.

Department of Radiology, Medical University Innsbruck, Austria.

 To evaluate whether ultrasound findings of the median nerve cross-section area (CSA) and wrist-to-forearm ratio (WFR) correlate with neurophysiological and patient-reported outcome after surgery for carpal tunnel syndrome (CTS).  Subjective pain, CSA, WFR, postoperative scar tissue formation and nerve conduction velocity in 21 hands of 20 patients with clinically confirmed CTS were examined before and after carpal tunnel release surgery. Group differences were compared via a 2-sided ratio paired t-test or one-way ANOVA, and correlations were calculated using a linear regression model.  There were no significant pre- and postoperative changes of the CSA of the median nerve (p = 0.293, 95 % CI 0.826 - 1.063) or WFR (p = 0.230, 95 % CI 0.757 - 1.074). The nerve conduction velocity (p < 0.0001, 95 % CI 0.753 - 0.886) and subjective pain during rest (p = 0.001, 95 % CI 1.615 - 5.797) and exercise (p = 0.008, 95 % CI 0.760 - 4.888) improved significantly, though. There was no correlation between changes in the median nerve CSA and nerve conduction velocity (p = 0.357, r = 0.217, R2 = 0.047) or reported pain intensity (p = 0.441, r = 0.200, R2 = 0.040).  Contrary to common assumptions, there is no significant reduction of the CSA of the median nerve after successful carpal tunnel release. Morphologic median nerve changes may persist for a longer period regardless of successful surgery and clinical improvement. Accordingly, ultrasound appears unsuitable as the primary means of assessing surgical success due to this "memory effect". · CSA of the median nerve does not change significantly after successful carpal tunnel release.. · Morphologic median nerve alterations may persist regardless of functional outcome ("memory effect").. · Therefore, ultrasound imaging is not ideally suited to assess the outcome after carpal tunnel release.. · Steinkohl Fabian, Gruber Leonhard, Gruber Hannes et al.

Triple hourglass-like fascicular constriction of the posterior interosseous nerve: a rare cause of PIN syndrome.

Arch Orthop Trauma Surg 2015 May 20;135(5):635-7. Epub 2015 Feb 20.

Department of Radiology, Innsbruck Medical University, Anichstrasse 35, 6020, Innsbruck, Austria,

Supinator syndrome or posterior interosseous nerve (PIN) syndrome is a compression neuropathy of the deep branch of the radial nerve in the region of the Arcade of Frohse. An extremely rare cause of an acute onset supinator syndrome is the hourglass-like fascicular constriction of the posterior interosseous nerve due to torsion. To our knowledge, only a limited number of cases which describe the sonographic appearance of fascicular torsions are known in the literature. We present a rare case of a supinator syndrome associated with hourglass-like constrictions of the PIN diagnosed by means of sonography.

Pollicization of the index finger in hypoplasia of the thumb. Experience with the method of Buck-Gramcko and retrospective analysis of the clinical outcome in a series of 19 pollicizations.

J Hand Microsurg 2009 Jun 10;1(1):17-24. Epub 2009 Jul 10.

Department for Plastic and Reconstructive Surgery, Medical University Innsbruck, Innsbruck, Austria.

Background: In congenital malformation of the thumb index finger pollicization is a proven method for constructing a new thumb all over the world.

Methods: A series of 19 pollicizations in 15 patients is presented. In all cases of index finger pollicization the method of Buck-Gramcko is used and the functional outcome is evaluated after Percival's method. Three special cases are described in detail and the preoperative evaluation with a CT-angiography in cases of complex malformations (case 3) for better planning of the surgical steps is recommended. The importance of parent's information soon after giving birth to a child with thumb hypoplasia is described in detail as the postoperative management.

Results: In children with bilateral deformities of the hand the surgery can be performed in one session, in only 2 cases a second operation was necessary. The postoperative results were excellent and good (Percival's measurement) and the children are now able to perfectly use their affected hand in their day-to-day activities.

Conclusion: Buck-Gramcko's method of pollicization in congenital thumb malformation gives excellent results. The preoperative planning and exactly following the four key steps is as important as the postoperative management.
