Morphological Relation of Peripheral Nerve Sheath Tumors and Nerve Fascicles: Prospective Study and Classification.

Removal of benign peripheral nerve sheath tumors (bPNST) represents a surgical challenge. The morphological relation of bPNST and healthy nerve fascicles are of utmost importance for achieving both removal of the entire tumor and preservation of functional integrity of the peripheral nerve. Thus, we intraoperatively assessed the morphological patterns between bPNST and nerve fascicles using photo documentation obtained between January 2009 and September 2021.

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.

Matched retrospective analysis of three different fixation devices for chevron osteotomy.

Chevron osteotomy with consecutive fixation is a commonly performed operative treatment option for hallux valgus deformities. The present retrospective study aims to compare the clinical and radiological outcome of novel bioabsorbable magnesium screw fixation with metal screw and Kirschner wire fixation. Eighteen matched triplets were assembled according to the following criteria: female gender, age difference less than 5 years, date of operation within 4 months, difference in preoperative intermetatarsal angle less than 5°, and equal experience of the first and second surgeon.

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.

Congenital Unilateral Hypertrophy of the Plantar Musculature with Multiple Toe Deformities: A Case Report and Literature Review.

Congenital unilateral hypertrophy of the plantar musculature is a rare condition, and to our knowledge, reports of only 14 cases have been previously published. As only one describes a concomitant orthopedic toe deformity, we report our case of abductor hallucis, flexor digitorum brevis, and abductor digiti minimi muscle hypertrophy in combination with hallux valgus and claw toe deformity as well as a laterally abducted fifth toe. Thus, this report presents the rare case of congenital hypertrophy of the plantar musculature associated with complex toe deformities.

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.

3D Printing for scaphoid-reconstruction with medial femoral condyle flap.

Three-dimensional (3D) printing has emerged as an innovative technology to derive a maximum benefit from high-resolution tomography images and virtual 3D reconstructions. The present study describes a novel technique using a 3D printed model for harvesting osteochondral medial femur condyle (MFC) flap to replace the proximal pole of the scaphoid in case of proximal avascular pole. MFC bone grafting has already proved to be reasonable surgical method for this indication.

A Head-to-Head Comparison of the Vascular Basis of the Transverse Myocutaneous Gracilis, Profunda Artery Perforator, and Fasciocutaneous Infragluteal Flaps: An Anatomical Study.

Background: Perforator flaps of the upper thigh or buttock provide a valuable secondary choice in autologous breast reconstruction. The purpose of this study was to compare the vascular territories and supplying vessels of the transverse myocutaneous gracilis flap, the profunda artery perforator flap, and the fasciocutaneous infragluteal flap.

Methods: In total, 26 lower limbs from 13 fresh specimens were investigated.

The versatility of the islanded posterior arm flap for regional reconstruction around the axilla.

Introduction: Defects in the region of the axilla pose a difficult reconstructive problem. Various methods for restoration have been described. We present our experience with the islanded posterior arm flap for regional reconstruction around the axilla.

Pedicled superficial inferior epigastric artery perforator flap for salvage of failed metoidioplasty in female-to-male transsexuals.

Metoidioplasty represents a viable option for female-to-male transsexual patients seeking gender reassignment surgery. The aim of this procedure is to create a microphallus with lengthening of the urethra to the tip of the hypertrophied and released clitoris. However, fistula formation and urethral obstruction might occur in the long term and reconstruction represents a challenging problem in this setting.

Perforasomes of the upper abdomen: an anatomical study.

Introduction: Pedicled perforator flaps in the trunk such as the DIEAP or the IMAP-flap have increasingly been used for reconstructive purposes. However, perforator flaps of the upper abdominal wall derived from the SEA and DIEA have not been widely reported in literature. The aim of this study was to investigate the vascular basis of perforator flaps of the upper abdominal wall based on the epigastric vascular axis and to describe the location and size of the individual flaps.

Further developments in the twisted-toe technique for isolated thumb reconstruction: our method of choice.

Background: Posttraumatic loss of the thumb is devastating. Toe-to-hand transfer is considered the criterion standard of reconstruction but is associated with donor-site issues. The twisted-toe technique uses parts from the great toe and the second toe, which allows for almost anatomical restoration of the donor foot.

Utilization of bilateral infragluteal flaps for correction of overaggressive gluteal liposuction.

Liposuction continues to be one of the most frequently performed aesthetic surgical procedures. Typically, good results can be achieved. However, this procedure is not without any associated risks, such as infection, embolism, or contour deformities.

Breast and chest wall reconstruction with the transverse musculocutaneous gracilis flap in Poland syndrome.

Poland syndrome is a complex chest wall deformity with unilateral hypoplasia of the breast and pectoralis muscle, with a missing anterior axillary fold in its most common form. The authors report their combined experience and technique with the transverse myocutaneous gracilis flap to reconstruct the chest wall and breast either alone or simultaneously. Between June of 2004 and July of 2010, 11 patients (two male patients) were operated on and 14 flaps were transplanted.
