[Treatment of the contracted first Commissure of the Hand: Literature Overview and own Experiences]. / Die Behandlung der kontrakten ersten Kommissur der Hand: Literaturübersicht und eigene Erfahrungen.

The freely movable thumb is of central importance for the function of the human hand. This mobility is necessarily linked to an undisturbed function of the commissure between the thumb and the index finger or, if the index finger is missing, the middle finger. A significant contracture of the first commissure, caused by whatever genesis, inevitably results in a significant loss of function up to almost complete inability to use. The surgical treatment of the first commissure often only affects the contracted skin. In some cases, however, it requires a multi-stage approach to fascia, muscles and joints, at the end of which there is the soft tissue expansion of the interspatium between the thumb and index finger. We mention old insights on the subject, give an overview of the literature, present our own experiences based on 5 cases and - according to the severity of the contracture - make a therapy recommendation.

Tranexamic Acid Use in Breast Surgery: A Systematic Review and Meta-Analysis.

BACKGROUND: The perioperative use of tranexamic acid (TXA) has become popular among plastic surgeons for a variety of surgical procedures. The aim of this study was to perform a systematic review and meta-analysis on the results reported in the literature regarding the effect of perioperative systemic TXA administration in breast surgery. METHODS: The PubMed, MEDLINE, Embase, CENTRAL, and CINAHL databases were searched for both randomized clinical trials and observational studies. Effect estimates were pooled across studies using random effects models and presented as weighted odds ratio with corresponding 95% confidence interval. RESULTS: A total of five studies encompassing 1139 patients undergoing mastectomy with or without immediate implant or free flap-based breast reconstruction or breast-conserving surgery with or without axillary lymph node dissection were included. Perioperative intravenous administration of TXA significantly reduced the risk for hematoma (7.3% versus 12.9%; OR, 0.43; 95% CI, 0.23 to 0.81) and seroma formation (11.5% versus 19.9%; OR, 0.57; 95% CI, 0.35 to 0.92) in comparison to the control group. In the studies measuring the postoperative drainage amount, the mean difference was 132 mL (95% CI, 220 to 44 mL). No thromboembolic event occurred in either group. The weighted surgical-site infection rate was higher in the control group (3.1% versus 1.5%). However, these data were too sparse to perform comparative meta-analysis. CONCLUSION: Evidence of this study suggests that perioperative administration of TXA significantly reduces the risk for postoperative hematoma and seroma formation in breast surgery, whereas the risk for thromboembolic events and postoperative infection is not increased.

Temporary spanning plate wrist fixation of complex distal radius fractures: a systematic review of 353 patients.

PURPOSE: Temporary spanning plate fixation of the wrist has been described as an alternative treatment method for complex distal radius fractures (DRfs). This systematic review aims to gain insight on clinical and radiological outcomes of this technique currently published in literature. METHODS: A comprehensive literature search of Pubmed, Embase, CENTRAL and CINAHL databases was conducted on November 5th 2020. All studies reporting on complications, functional, patient-rated and radiological outcomes of temporary spanning plate wrist fixation of DRFs in adult patients were included. RESULTS: Two prospective and eight retrospective cohort studies were included encompassing 353 patients with of 357 DRFs. The overall mean age was 53 years (range 19-95 years). Overall mean follow-up ranged from 6 months to 8.8 years. The union rate was 99.4%. Plate removal was performed on average 4.5 months after initial operation (range 1.1-28.9 months). The most frequently reported complication was implant failure with an incidence of 3.1%. Mean flexion/extension, pronation/supination and radial/ulnar inclination arc averaged 96.6°, 151.5° and 36.5°, respectively. Grip strength averaged 79.7% of the contralateral side. Mean DASH and PRWE scores were 22.9 and 16 points, respectively. Radiological indices were all within the acceptable limits. CONCLUSIONS: Temporary spanning plate wrist fixation is a safe method for the treatment of complex DRFs. This technique can exploit the advantages of temporary wrist immobilization without the disadvantages of external fixation. With these aspects in mind, the spanning plate can serve as a valuable tool in the treatment of complex intra-articular DRFs.

The spanning plate as an internal fixator in complex distal radius fractures: a prospective cohort study.

OBJECTIVE: Minimal invasive temporary spanning plate (SP) fixation of the wrist has been described as an alternative treatment method in complex distal radius fractures (DRFs). The purpose of this study is to conduct an outcome analysis of all consecutive DRFs treated by SP fixation representing the so far largest published patient cohort outside the United States. METHODS: Indication for SP fixation include DRFs with severe metaphyseal comminution, radiocarpal fracture dislocations with concomitant ligamentous injuries and very distal intra-articular fractures lacking the possibility of adequate plate anchoring. All consecutive patients undergoing SP fixation of DRFs were prospectively included in a single level I trauma centre between 01/01/2018 and 31/12/2020. For functional and patient-rated outcome analysis only patients who completed the 12 month follow-up were included. RESULTS: In the mentioned timeframe, a total of 562 DRFs were treated operatively of which 28 underwent SP fixation. Average age was 58.1 years (range 22-95 years). The fracture type ranged from AO/OTA type B1.1 to C3.3 and included 8 fracture dislocations. SP removal was performed on average 3.7 months after the initial operation (range 1.4-6.5 months). Twenty-five patients completed the 12 month follow-up (mean 14.5 months, range 12-24). Radiological evidence of fracture healing appeared on average 9.9 weeks (range 5-28 weeks) after the initial operation. One patient experienced asymptomatic non-union. Mean radial inclination, volar tilt and ulnar variance at 1 year were all within the acceptable limit predictive of symptomatic malunion. Complications included two patients with tendon rupture and one patient with extensor tendon adhesions needing tenolysis at the time of plate removal leaving an overall complication rate of 12%. There was no implant failure and no infection. Mean satisfaction score was 8.3 (range 4-10) and mean visual analogue scale for resting pain was 0.8 (range 0-5). The mean PRWE score was 17.9 (range 0-59.5) and the mean DASH score was 16.6 (range 0-60.8). Grip strength averaged 23 kg (range 4-74 kg) amounting to 68% of the opposite side. Range of motion regarding the extension/flexion, radial/ulnar abduction and pronation/supination arc reached 72%, 77% and 95% compared to the unaffected side, respectively. CONCLUSIONS: The radiological, functional and patient-rated outcomes in this study are remarkably good considering the complexity of the included fractures. Therefore, this method represents a valuable alternative for the treatment of complex DRFs in selected patients.

[An introduction into the use of fabricated chimeric flaps in replantation surgery of digits]. / Das Chimera-fabricata-Lappen-Konzept in der Replantationschirurgie von Fingern ­ eine Einführung.

Since microsurgical finger replantations started to be successfully performed at the beginning of the 1960 s, there has been an evolution in the techniques for restoring blood flow to the amputated fingers. Initially, end-to-end anastomoses were performed. Later on, vascular grafts - predominantly vein interpositional grafts - were successfully used for difficult avulsion injuries. These vascular grafts were extended by microvascular flaps in the form of flow-through flaps in cases with simultaneous soft tissue loss. A further development of these techniques has been achieved by the replantation of amputated fingers with the help of fabricated chimeric flaps. The amputated finger is anastomosed microsurgically with a flap "in tabula" before the actual replantation. Only then is the fabricated chimera replanted as a construct. The latest development so far is heterotopic replantation with secondary replantation in the form a fabricated chimeric flap. By way of introduction, we describe three cases in which we have successfully applied this concept of fabricated chimeric flap surgery for orthotopic thumb replantations.

Surgical Treatment of Brooke-Spiegler Syndrome.

ABSTRACT: Brooke-Spiegler Syndrome (BSS) is a very rare autosomal dominant hereditary disease which arises from heterozygous mutations in the CYLD gene. Patients with BSS are predisposed to multiple skin appendage tumors such as cylindromas, which are benign tumors occurring mainly on the scalp. The tumors mostly appear around puberty and usually show slow growth throughout life. Malignant cylindroma formation in BSS patients has been reported. Apart from the skin, major and minor salivary glands have rarely been involved.We here report a case of a 46-year-old female patient with BSS presenting with multiple aesthetically and functionally unpleasing cylindromas covering almost her entire hair-bearing scalp with further tumors on her face. Interestingly, her parotid glands were enlarged and showed multiple lesions with a diameter up to 18 to 20 mm. She was successfully treated by total subgaleal scalp excision and coverage through a dermal substitute and split thickness skin graft. Constant follow-up imaging was initiated to prevent unhindered tumor growth of salivary glands.

Triquetrum Excision in Radioscapholunate Arthrodesis for Posttraumatic Radiocarpal Osteoarthritis With Ulnar Impaction Syndrome.

Dependent on fracture type, concomitant carpal injuries, and operative treatment, distal radius fractures can lead to symptomatic radiocarpal osteoarthritis. In addition, radial shortening can cause ulnar impaction syndrome. Radiocarpal arthrodesis and ulnar shortening osteotomy are known and frequently applied surgical procedures for each of those pathologies. There are limited data concerning treatment options for a combined disorder. The presented technique in this article demonstrates that radioscapholunate arthrodesis with distal pole scaphoidectomy and total triquetrum excision successfully treats both symptomatic radiocarpal osteoarthritis and ulnar impaction syndrome without further surgery on the ulna.

SPECT/CT in Postoperative Hand and Wrist Pain.

In this review we summarize the current evidence and experience regarding the performance of SPECT/CT in the evaluation of patients with postoperative painful wrist or hand. There is a wide range of operative wrist and hand interventions due to congenital, traumatic, degenerative, or inflammatory diseases. A significant number of patients suffer from pain after operative procedures. Several imaging modalities have been used to evaluate the reason for painful postoperative wrists like standard conventional x-rays, ultrasound, CT, MRI, or bone scintigraphy. In the last decade, bone SPECT/CT has offered a new approach in combining metabolic and morphologic cross-sectional information in patients with painful postoperative wrists and is increasingly used if standard imaging fails to identify the pain generator. SPECT/CT is less hampered by artifacts caused by metallic implants and shows more details of the cortical bone compared with MRI. MRI is generally superior regarding visualization of soft tissue structures like tendons, synovia, cartilage, muscles, and ligaments. SPECT/CT arthrography has been established to enable the assessment of cartilage and ligament tears.

Hypothenar hammer syndrome: caused by a muscle anomaly? A case report with review of the literature.

The hypothenar hammer syndrome (HHS) is a rare entity of secondary Raynaud's phenomenon. The blunt hypothenar trauma causes a lesion of the vessel wall with a consecutive thrombosis or aneurysm of the ulnar artery at the Guyon's canal. Different risk factors are discussed such as nicotine abuse, or a muscle anomaly in the Guyon's canal. To date, there are five case reports published about muscle anomalies and HHS. We present a case of a 51-year-old shipbuilder with a unilateral HHS on his right dominant hand with a bilateral muscle anomaly. We successfully treated the patient by resection of the aneurysm without a resection of the atypical muscle.

SPECT/CT arthrography.

Single photon emission CT (SPECT)/CT arthrography, the combination of CT arthrography and late phase bone SPECT/CT, has been developed in 2011 and so far used in knee, ankle and wrist joints. SPECT/CT offers functional information about increased bone turnover in combination with morphological details. Compared with SPECT/CT alone, additional intra-articular contrast enables the assessment of cartilage, menisci, ligaments and loose bodies. SPECT/CT arthrography is a promising alternative technique for the evaluation of internal derangement of joints in patients with MR contraindications and/or metallic implants. In this article, we review and report our 5-year experience with this technique illustrated with patient examples and give a perspective for future applications.

The Vilkki Procedure as an emergency treatment in an apocalyptical hand injury - a case report and first description.

He underwent a complex reconstruction of his right adominant hand including a heterotopic thumb replantation into the distal radius and combined with an emergency flow-through anterolateral thigh flap.

[Long-term outcome analysis of subjective and objective parameters after breast reduction in 159 cases: Patients judge differently from plastic surgeons]. / Subjektive und objektive Langzeitanalyse nach Mammareduktionsplastik in 159 Fällen: Patientinnen urteilen anders als Plastische Chirurgen.

INTRODUCTION: This work assessed both subjective and objective postoperative parameters after breast reduction surgery and compared between patients and plastic surgeons. PATIENTS AND METHODS: After an average postoperative observation period of 6.7 ± 2.7 (2 - 13) years, 159 out of 259 patients (61 %) were examined. The mean age at the time of surgery was 37 ± 14 (15 - 74) years. The postoperative anatomy of the breast and other anthropometric parameters were measured in cm with the patient in an upright position. The visual analogue scale (VAS) values for symmetry, size, shape, type of scar and overall satisfaction both from the patient's and from four plastic surgeons' perspectives were assessed and compared. RESULTS: Patients rated the postoperative result significantly better than surgeons. Good subjective ratings by patients for shape, symmetry and sensitivity correlated with high scores for overall assessment. Shape had the strongest influence on overall satisfaction (regression coefficient 0.357; p < 0.001), followed by symmetry (regression coefficient 0.239; p < 0.001) and sensitivity (regression coefficient 0.109; p = 0.040) of the breast. The better the subjective rating for symmetry by the patient, the smaller the measured difference of the jugulum-mamillary distance between left and right (regression coefficient -0.773; p = 0.002) and the smaller the difference in height of the lowest part of the breast between left and right (regression coefficient -0.465; p = 0.035). There was no significant correlation between age, weight, height, BMI, resected weight of the breast, postoperative breast size or type of scar with overall satisfaction. CONCLUSION: After breast reduction surgery, long-term outcome is rated significantly better by patients than by plastic surgeons. Good subjective ratings by patients for shape, symmetry and sensitivity correlated with high scores for overall assessment. Shape had the strongest influence on overall satisfaction, followed by symmetry and sensitivity of the breast. Postoperative size of the breast, resection weight, type of scar, age or BMI was not of significant influence. Symmetry was the only assessed subjective parameter of this study that could be objectified by postoperative measurements.

[Defect coverage of the hand using a rare Siamese combined flap]. / Defektdeckung an der Hand mit einer seltenen siamesischen Lappenkombination.

We report 2 cases of extensive soft tissue defects simultaneously affecting the palm and dorsum of the hand. The defect was covered with a Siamese flap combination consisting of a free, distally extended lateral upper arm flap with microvascular anastomosis, and a posterior interosseous artery flap. We discuss possible indications, the operative technique and advantages versus disadvantages of this rarely applied flap combination.
