How a Gauze Sponge Roll Enhances Surgical Exposure in Thumb Carpometacarpal Arthroplasty: A Technical Note.

Thumb carpometacarpal arthroplasty has become a widely used standard technique in the surgical treatment of thumb carpometacarpal osteoarthritis. One of the most critical steps during this procedure is proper surgical exposure of the trapezium and the base of the first metacarpal to allow for prosthesis implantation. This article introduces a surgical technique in which a roll constructed from gauze sponges tightly wrapped with medical tape facilitates several steps in thumb carpometacarpal arthroplasty.

Periprosthetic radiolucency in total wrist arthroplasty: a radiographic study.

This retrospective study investigates the incidences of periprosthetic radiolucency and the position of the prosthesis in patients who underwent total wrist arthroplasty. A total of 50 patients with a mean age of 58 years (SD 11) were included. The available dorsopalmar and lateral radiographs were categorized into the following groups: immediately postoperative and 1, 2, 3, 5 and beyond 6 years postoperatively.

Liparthroplasty for Thumb Carpometacarpal Joint Osteoarthritis: A Case Series with Median 5 Years of Follow-Up.

Liparthroplasty has recently been discussed as a promising bridging therapy after failed conservative treatment options to postpone arthroplasty surgery of the thumb carpometacarpal joint as long as possible. The current study investigates the sustainability of this method in seven stage II and twenty-four stage III osteoarthritis patients (twenty-seven female and four male cases). Data were evaluated preinterventionally, six months postinterventionally, and two years postinterventionally, as well as a final follow-up assessment after median 5.

Total Wrist Arthroplasty for Posttraumatic Wrist Osteoarthritis: A Cohort Study Comparing Three Indications.

Scapholunate ligament ruptures and scaphoid nonunion with consecutive advanced collapse (SLAC and SNAC wrists) as well as intra-articular distal radius fractures (DRF) are prone to cause posttraumatic wrist osteoarthritis. The aim of this study was to compare the outcomes of these indications for total wrist arthroplasty. We included 13, 11, and 8 patients with an overall mean age of 60 ± 9 years in the SLAC, SNAC, and DRF cohort, respectively.

Wrist Hemiarthroplasty for Complex Intraarticular Distal Radius Fracture in a Patient with Manifest Osteoporosis.

Distal radius fracture (DRF) is one of the most common fractures of the elderly. The higher the degree of joint surface destruction, and the more adverse factors are involved, the more challenging proper treatment becomes. In this regard, osteoporosis as underlying systemic disease, chondropathy or degeneration of adjacent wrist bones as well as incompliance significantly impair the success of the chosen primary therapy.

Metacarpal reconstruction with a medial femoral condyle flap based on a 3D-printed model: a case report.

Metacarpal bone reconstruction renders a surgical challenge. We describe a case using 3D printing assisted medial femoral condyle flap for extensive metacarpal reconstruction after wide resection of a large giant cell tumor recurrence. Thus, the length and stability of the entire third ray could be restored without any tumor recurrence.

Botulinum Toxin Injection for Painful Adductor Pollicis Contracture after Thumb Carpometacarpal Resection Arthroplasty.

Pollux adductus deformity is an accompanying symptom of thumb carpometacarpal osteoarthritis. We describe a case of a patient who presented with increased muscle tone of the adductor pollicis muscle and chronic pain in the thenar musculature, i.e.

TOUCH Prosthesis for Thumb Carpometacarpal Joint Osteoarthritis: A Prospective Case Series.

The dual mobility concept currently represents the newest generation of thumb carpometacarpal prostheses. The aim of this study was to evaluate the short-term outcomes of TOUCH prosthesis. From September 2019 to July 2020, 40 prosthesis were implanted in 37 patients suffering from symptomatic stage III osteoarthritis.

Seasonal impact on surgical site infections and wound healing disturbance in carpal tunnel surgery: A retrospective cohort study.

Carpal tunnel syndrome is the most common entrapment syndrome of a peripheral nerve. The gold standard treatment is open carpal tunnel release which has a high success rate, a low complication rate, and predictable postoperative results. However, it has not been analysed yet if there is a seasonal influence on complications for carpal tunnel release, a highly elective procedure.

Proximal Row Carpectomy with Total Scapoidectomy vs. Conventional Carpal Resection for ReMotion Total Wrist Arthroplasty.

High complication rates in total wrist arthroplasty (TWA) still lead to controversy in the medical literature, and novel methods for complication reduction are warranted. In the present retrospective cohort study, we compare the outcomes of the proximal row carpectomy (PRC) method including total scaphoidectomy ( = 22) to the manufacturer's conventional carpal resection (CCR) technique, which retains the distal pole of the scaphoid ( = 25), for ReMotion prosthesis implantation in non-rheumatoid patients. Mean follow-up was 65.

[An innovative concept for microsurgical training: a feedback analysis].

Background: There has been a shift in microsurgical education towards simulation training. Hence a number of training programs are being proposed to educate aspiring microsurgeons. However, it is challenging to master the skill of microsurgery and no program has proposed a fully satisfactory training model to date.

Autologous Fat Transplantation for Thumb Carpometacarpal Joint Osteoarthritis (Liparthroplasty): A Case Series with Two Years of Follow-UP.

Adipose-derived mesenchymal stem cell (ASC) therapy is currently a focus of regenerative medicine. Lipoaspirate is rich in ASCs and is evolving into a promising, less-invasive tool to treat thumb carpometacarpal osteoarthritis as compared with common surgical techniques, for example, trapeziectomy or prosthesis implantation. The present study aimed to examine the effect of 1 mL intraarticular lipoaspirate injection (liparthroplasty) in 31 thumb carpometacarpal osteoarthritis patients (27 woman and four men) with a median age of 58 (interquartile range (IQR) of 10) years and Eaton-Littler Stage 2 or 3.

Radial and palmar active range of motion measurement: reliability of six methods in healthy adults.

The current study aims to assess the reliability of 6 range-of-motion measurement methods for the thumb carpometacarpal joint: Pollexograph-thumb, Pollexograph-metacarpal, radius-metacarpal goniometry, intermetacarpal goniometry, intermetacarpal distance, and thumb-distal-interphalangeal distance. A senior hand surgeon, an experienced resident, and a less experienced research fellow evaluated the dominant hands of 29 healthy subjects. All 6 methods were performed for radial adduction, radial abduction, and palmar abduction, but only distance methods were measured for palmar adduction.

Effect of Music on the Efficiency of Performing a Microsurgical Arterial Anastomosis: A Prospective Randomized Study.

 Music is commonly played in operating rooms. Because microsurgery demands utmost concentration and precise motor control, we conducted the present study to investigate a potentially beneficial impact of music on performing a microsurgical anastomosis.  We included a novice group (15 inexperienced medical students) and a professional group (15 experienced microsurgeons) in our study.

Total arthroplasty with Ivory prosthesis versus resection-suspension arthroplasty: a retrospective cohort study on 82 carpometacarpal-I osteoarthritis patients over 4 years.

Background: To elucidate the performance of carpometacarpal-I joint prostheses in comparison with the current gold standard treatment, resection-suspension arthroplasty (RA), we conducted a study comparing outcomes of the Ivory prosthesis to those of a cohort of patients receiving RA.

Methods: Initially, we had enrolled 34 prosthesis patients and 48 RA patients, of which 5 and 11 were lost to follow-up. We defined Eaton/Littler stage 3 osteoarthritis, no previous surgery, no concomitant arthrosis, no rheumatic arthritis, no history of trauma and a minimum follow-up period of 2 years as inclusion criteria.

[Consensus of the German-Speaking Society for Microsurgery of Peripheral Nerves and Vessels (DAM) on minimum standards for microsurgical training courses and accreditation - Minimum Standards for Microsurgical Training Courses and Accreditation].

Microsurgical training courses are an integral part of surgical education and training. Due to the changes in the surgical everyday routine, the competence and skills training outside the operating room has an increasingly important status. Multi-day, hands-on exercises with different models of increasing difficulty use artificial, avital and vital microsurgical models.

Elektra prosthesis versus resection-suspension arthroplasty for thumb carpometacarpal osteoarthritis: a long-term cohort study.

The present study compares 34 patients with thumb carpometacarpal osteoarthritis (37 thumbs) treated with the Elektra® prosthesis, with 18 patients (18 thumbs) treated with resection-suspension arthroplasty, with an overall mean follow-up period of 13.3 years. Evaluation with disability of arm and shoulder scores, pain via visual analogue scale and range of motion (radial and palmar abduction, and opposition) indicated no significant difference.

Re-motion total wrist arthroplasty: 39 non-rheumatoid cases with a mean follow-up of 7 years.

We evaluated the outcomes of the Re-motion total wrist arthroplasty in 39 non-rheumatoid patients. The mean follow-up was 7 years (range 3-12). Postoperative wrist flexion-extension and radial-ulnar deviation as well as the scores of the Disability of Arm Shoulder and Hand questionnaire and the visual analogue scale pain scores improved significantly.

Optical magnification should be mandatory for microsurgery: scientific basis and clinical data contributing to quality assurance.

Background: Microsurgical techniques are considered standard procedures in reconstructive surgery. Although microsurgery by itself is defined as surgery aided by optical magnification, there are no guidelines for determining in which clinical situations a microscope or loupe should be used. Therefore, we conducted standardized experiments to objectively assess the impact of optical magnification in microsurgery.

Strategies for the reduction of live animal use in microsurgical training and education.

Education and training in microsurgical techniques have historically relied on the use of live animal models. Due to an increase in the numbers of microsurgical operations in recent times, the number of trainees in this highly-specialised surgical field has continued to grow. However, strict legislation, greater public awareness, and an increasing sensitivity toward the ethical aspects of scientific research and medical education, emphatically demand a significant reduction in the numbers of animals used in surgical and academic education.

A comparison of pretreatment with a topical combination of nonivamide and nicoboxil and surgical delay in a random pattern skin flap model.

Delay procedures are intended to increase flap safety in otherwise risky flaps. In general they are of surgical nature, making an additional operation necessary. To overcome this drawback, non-surgical alternatives that may be as effective as the surgical procedure are constantly sought.

Intraluminal endoscopic evaluation of microvascular anastomosis.

Microsurgery is an established technique in different surgical disciplines. Training in the laboratory remains the mainstay for delivering optimal performance in the operating room. Routine evaluation of microsurgical anastomosis during training usually consists of longitudinal splitting of the performed anastomosis.
