Posterolateral Locked Plate and Percutaneous Medial Screw Fixation for Distal Humerus Fractures in Elderly.

A high incidence of ulnar nerve-related complications has been reported in open reduction and internal fixation for distal humerus fractures (DHFs). To minimise ulnar nerve damage, we used a percutaneous medial screw combined with a posterolateral plate in the elderly. The aim of this study was to evaluate the postoperative complications and functional outcomes of this method.

Comparing clinical and aesthetic outcomes of cross-finger and homodigital reverse digital artery island flap for fingertip injuries: A single-center retrospective cohort study.

Background: Reverse homodigital artery island flap (RHDI) has been reported to have some postoperative complications. Cross-finger reverse digital artery island flap (CRDI), which is harvested from an adjacent intact finger, has been used to decrease these complications. This study aimed to provide a review of the CRDI procedure and compare the clinical outcomes of CRDI with those of RHDI.

The Results of Hook Plate Fixation for Palmar Fracture Dislocation of the Proximal Interphalangeal Joint.

Purpose: This study aimed to present the clinical outcomes of the dorsal plating technique for palmar fracture dislocations of the proximal interphalangeal (PIP) joint. This plating technique minimizes dissection and interference with the finger extensor mechanism.

Methods: We treated seven patients (with a mean age of 39.

Limiting Levels of Fingertip Replantation Without Venous Anastomosis.

Purpose: This study aimed to compare the success rates of fingertip replantation with and without venous anastomosis.

Methods: This retrospective study included 132 patients with 148 fingertip injuries who had undergone fingertip replantation (Ishikawa's classification I‒IV) between 2003 and 2020 at our hospital. Among them, 117 and 15 were men and women respectively, and their mean age was 43 years.

Comparing Clinical and Aesthetic Outcomes of Digital Artery Flap Using Nail Bed Graft for Fingertip Amputation with Replantation.

Background: Digital artery flap (DAF) with nail bed graft is a simple method to preserve finger length for fingertip amputations. This study compared the clinical and aesthetic outcomes between replantation and DAF.

Methods: Patients who underwent replantation or DAF for a single fingertip amputation (Ishikawa subzone II or III) at the authors' hospital from 2013 to 2021 were retrospectively evaluated.

Satisfactory mid- to long-term clinical and radiographic outcomes after surgical treatment of radial neck fracture in 10 children.

Complications after surgical treatment of pediatric radial neck fractures are common. The purpose of this study was to evaluate the mid- to long-term clinical and radiographic outcomes after surgical treatment of pediatric radial neck fractures. We assessed 10 children who had been surgically treated for radial neck fractures.

The CeCORD-J study on collagenase injection versus aponeurectomy for Dupuytren's contracture compared by hand function and cost effectiveness.

This study compared hand function and the cost-effectiveness of treatment between collagenase Clostridium histolyticum (CCH) injection and limited fasciectomy for patients with Dupuytren's contracture (DC). The CeCORD-J study is a prospective, multicenter, non-randomized controlled, observational study of two parallel groups. Participants were DC patients with multiple affected fingers, including flexion contracture of the proximal interphalangeal (PIP) joint.

Iatrogenic peripheral nerve injuries - Common causes and treatment: A retrospective single-center cohort study.

Background: Iatrogenic nerve injuries can result from surgical damage. Thus, physicians should be aware of the risk factors and procedures that need to be followed in such patients. The purpose of this study was to examine data pertaining to patients with known iatrogenic nerve injuries and to elucidate the detailed causes of these injuries, the affected nerves, and the type of surgical procedures for treatment.

Difference in Carpal Alignment between Scapholunate Dissociation and Kienbock Disease: A Retrospective Study.

 Scapholunate dissociation is the most frequent type of wrist instability and, if untreated, can lead to wrist osteoarthritis, known as scapholunate advanced collapse. Kienbock disease can also lead to wrist osteoarthritis. Both involve carpal instability; however, the possibility of completely different mechanisms underlying each ligamentous state and carpal malalignment must be considered.

Treatment of Multiple Digit Amputation in an Infant Using an Abdominal Pocket Combined with Composite Grafts of the Amputated Distal Phalanxes and Nails.

Retention of the distal phalanxes is important in the treatment of multiple digit amputations in infants to preserve the digit length and nail for functional and cosmetic reasons. We report the case of a 22-month-old boy with multiple digit amputations of his left index, middle, and ring fingers, which were severely mangled and not suitable for replantation. We propose the usefulness of the abdominal pocket method combined with composite grafts of the amputated phalanxes and nails and report the outcome of our case, with 2-year follow-up.

Survival Rate of Limb Replantation in Different Age Groups.

Revascularization of damaged limbs/digits is technically feasible, but indications for surgical replantation remain controversial. The authors analyzed the survival rate of upper limb amputations and the associated factors in different age groups. They grouped 371 limb/digit amputees (average age, 44 years; range, 2-85 years) treated in their hospital during the past 10 years into three groups based on age (young, ≤ 15 years,  = 12; adult, 16-64 years,  = 302; elderly, ≥ 65 years,  = 57) and analyzed their injury type (extent of injury and stump status), operation method, presence of medical complications (Charlson comorbidity index), and survival rate.

Near-infrared indocyanine dye permits real-time characterization of both venous and lymphatic circulation.

We investigated the optical properties of a near-infrared (NIR) fluorochrome, di-β-cyclodextrin-binding indocyanine derivative (TK-1), and its pharmacokinetic differences with indocyanine green (ICG). TK-1 was designed to have hydrophilic cyclodextrin molecules and, thus, for higher water solubility and smaller particle sizes than the plasma protein-bound ICG. We compared optical properties such as the absorption and fluorescence spectra, quantum yield, and photostability between both dyes in vitro.

Topical bFGF Improves Secondary Lymphedema through Lymphangiogenesis in a Rat Tail Model.

Background: Secondary lymphedema is a common complication of cancer therapy, but options for treating lymphedema are essentially ineffective and limited. On the contrary, lymphangiogenic growth factors accelerate lymphangiogenesis and improve lymphedema.

Methods: Rat tail models of lymphedema were assigned to groups that received either daily topical basic fibroblast growth factor (bFGF) or saline (control) groups.

Novel intramedullary-fixation technique for long bone fragility fractures using bioresorbable materials.

Almost all of the currently available fracture fixation devices for metaphyseal fragility fractures are made of hard metals, which carry a high risk of implant-related complications such as implant cutout in severely osteoporotic patients. We developed a novel fracture fixation technique (intramedullary-fixation with biodegradable materials; IM-BM) for severely weakened long bones using three different non-metallic biomaterials, a poly(l-lactide) (PLLA) woven tube, a nonwoven polyhydroxyalkanoates (PHA) fiber mat, and an injectable calcium phosphate cement (CPC). The purpose of this work was to evaluate the feasibility of IM-BM with mechanical testing as well as with an animal experiment.

Pathological mechanism of musculoskeletal manifestations associated with CRPS type II: an animal study.

Patients with complex regional pain syndrome (CRPS) often complain of abnormal sensations beyond the affected body part, but causes of this spread of musculoskeletal manifestations into contiguous areas remain unclear. In addition, immobilization can predispose to the development of CRPS. We examined functional, biochemical, and histological alterations in affected parts, including contiguous zones, using an animal model.
