Although rare, the thumb can trigger because of de Quervain disease. An 18-year-old woman presented with painful triggering during thumb movements. Physical examination revealed locking upon thumb extension and painful snapping upon thumb flexion, with tenderness over the first extensor compartment. During the ultrasonography examination, the exten...

Recently, better outcomes have been reported when up-to-date developments in flexor tendon surgery and therapy were followed. Slightly tensioned multistrand repairs, judicious venting of pulleys, and early active motion are widely accepted principles. In addition to these principles, tailoring of the repair according to intraoperative active moveme...
Article
This case series determines the clinical outcomes of relative motion extensor splints (RMES) in extensor mechanism repairs. Nine patients who underwent extensor tendon repair, juncturae tendinum or sagittal band repair were included. A forearm-based volar blocking wrist splint was applied after surgery. The RMES was configured at the initial hand t...

Background: Stack splint is commonly used for mallet finger treatment but patients had a tendency to frequently remove it because of skin complications. We hypothesized that a comprehensively instructed splinting regime would increase patients’ compliance and lead to favorable outcomes with fewer skin complications. The aims of this study were to a...

Introduction Posttraumatic brachial plexus (BP) palsy was used to be treated by reconstruction with nerve grafts. For the last two decades, nerve transfers have gained popularity and believed to be more effective than nerve grafting. The aim of this systematic review was to compare elbow flexion restoration with nerve transfers or nerve grafting af...

Objectives: Hand surgery has been a major theme throughout the education of orthopedics and traumatology (OT) along with plastic, reconstructive, and aesthetic (PRA) surgery residents. However, to work as a hand surgeon during compulsory health service (CHS) is a new topic for Turkey. We aimed to share the elective surgical experience of six hand s...

Here, we report our experience with railings causing injuries by penetrating the upper extremities, and aim to call attention to spiked railing injuries in children. METHODS: We report on five children with a mean age of 8.8. All of...

Arthrofibrosis is the abnormal proliferation of fibrous tissue in a joint with an unclear etiopathogenesis that leads to loss of motion, pain, muscle weakness, swelling, and functional limitation. The incidence of knee arthrofibrosis varies from 0 % to 57 % depending on the severity of injury. In the knee, arthrofibrosis may present as a localized...

Osteoarthritis (OA) is a complex "whole joint" disease pursued by inflammatory mediators, rather than purely a process of "wear and tear". Besides cartilage degradation, synovitis, subchondral bone remodeling, degeneration of ligaments and menisci, and hypertrophy of the joint capsule take parts in the pathogenesis. Pain is the hallmark symptom of...
Chapter
Meniscal tissue is essential for shock absorption, load distribution, joint lubrication, and proprioception. Removal of meniscal tissue usually causes subsequent degeneration of cartilage tissue over time. Therefore, repair rather than removal is essential when possible. Reparability of a tear depends on different factors as does the success of rep...

Background: The choice of prosthesis in hemiarthroplasty is controversial for geriatric patients after femoral neck fracture. We hypothesised that selection criteria for unipolar or bipolar prostheses could be constructed based on factors affecting mortality. Aims: The aims of this retrospective study were: (1) to determine the factors affecting m...

Any intraoperative rotational malalignment during intramedullary nailing (IMN) of femoral shaft fractures will become permanent. We hypothesized that rotational malalignment of the femur and its compensatory biomechanics may induce problems in the hip, knee, patellofemoral and ankle joints. We purposed to clarify the influence of a femoral rotation...
Article
The purpose of this study was to describe an arthroscopic technique for lateral parameniscal cyst (LPC) decompression with preservation of meniscal substance and to report the short- to mid-term outcome of 20 patients.

We hypothesized that regional migratory osteoporosis (RMO) and transient osteoporosis of the hip (TOH) terms describe a common disease process. Therefore, based on our patient, we aimed to review the pathogenesis, diagnosis, and treatment of both diseases. The patient was a pregnant woman in her third trimester with sacral insufficiency fracture, w...

We hypothesized that combined peripheral nerve block (CPNB) technique might reduce mortality in hip fracture patients with the advantage of preserved cardiovascular stability. We retrospectively analyzed 257 hip fracture patients for mortality rates and affecting factors according to general anesthesia (GA), neuraxial block (NB), and CPNB technique...
Article
In Sanders' classification of calcaneus fractures, the medial fracture line (subtype C) is close to the tarsal canal, which contains an artery for the talus and calcaneus. We hypothesized that because of this brittle vascular localization, patients with C line fracture patterns might describe radiologic subtalar arthritis more often and have more c...
Article
We present a case report involving the flexor digitorum accessorius longus (FDAL) tendon which travels through a fibro-osseous tunnel together with the flexor hallucis longus (FHL) tendon, causing a stenosing tenosynovitis.
