Background: Finger injuries caused by green onion cutting machines in Korean kitchens have unique characteristics of an incomplete amputation in which multiple parallel soft tissues and blood vessels are injured in the same form. In this study, we aimed to describe unique finger injuries and to report the treatment outcomes and experiences of performing possible soft tissue reconstructions. Methods: This case series study included 65 patients (82 fingers) from December 2011 to December 2015. The mean age was 50...

A 40-year-old patient and a 45-year-old patient presented with chronic dorsal and lateral subluxation of the proximal interphalangeal (PIP) joint of the little finger and underwent surgeries. Through a dorsal approach, the ulnar lateral band was transected and transferred to the radial side through the volar side of the PIP joint. The transferred lateral band and the remnant of the radial collateral ligament were secured with an anchor on the radial side of the proximal phalanx. Satisfactory results were obtained without the loss of flexion and recurrence of subluxation of the finger...

Extraskeletal chondroma comprises synovial chondromatosis, intracapsular chondroma and soft tissue chondroma, its presentation in the hand, however, is very rare. A 42-year-old woman presented with a mass around right fourth metacarpophalangeal (MCP) joint. She had no pain or discomfort in activities. The radiographs showed soft tissue swelling, but no calcification or ossifying lesions. The magnetic resonance imaging (MRI) showed a lobulated juxta-cortical encircling mass existing around the fourth MCP joint...

Background: Ulnar neuropathy at the elbow is the second most common upper extremity compressive neuropathy and surgical treatment often involves surgical trainee involvement. The primary aim of this study is to determine the effect of trainees and surgical assistants on outcomes surrounding cubital tunnel surgery. Methods: This retrospective study included 274 patients with cubital tunnel syndrome who underwent primary cubital tunnel surgery at two academic medical centres between 1 June 2015 and 1 March 2020...

Background: Infiltration is one of the treatment options for lateral epicondylosis, a degenerative process in the tendon of the musculus extensor carpi radialis brevis. The aim of this study was to evaluate the clinical outcome of a standardised fenestration technique, the Instant Tennis Elbow Cure (ITEC) technique, with injection of betamethasone versus autologous blood. Methods: A prospective comparative study was performed. Twenty-eight patients received an infiltration with 1 mL betamethasone, in combination with 1 mL 2% lidocaine...

Background: Limb length discrepancy (LLD) is a frequent observation in children with birth brachial plexus palsy (BBPP) and a common concern among parents. A common assumption is that the LLD decreases if the child is using the involved limb more. However, there is no literature evidence for this assumption. The present study was conducted to assess the correlation between the functional status of the involved limb and the LLD in children with BBPP. Methods: One hundred consecutive patients (age > 5 years) with unilateral BBPP seen at our institute underwent measurements of limb lengths to assess the LLD...

Background: Open reduction and internal fixation with a plate is one of the alternative treatments for fracture-dislocation of the proximal interphalangeal (PIP) joint. However, it does not always lead to satisfactory results. The aim of this cohort study is to describe the surgical procedure and discuss the factors affecting the treatment results. Methods: We retrospectively reviewed 37 cases of consecutive unstable dorsal fracture-dislocation of the PIP joint treated using a mini-plate. The volar fragments were sandwiched with a plate and dorsal cortex, and screws were used as subchondral support...

Background: The carpometacarpal (CMC) joint of the thumb is the second most common site of osteoarthritis in the hand. Clinical severity stage of CMC joint arthritis has not been correlated with the pain level of the patient. Recently, the association of joint pain with patient psychological factor, such as depression or case-specific personality, has been investigated. This study was designed to determine the impact of psychological factors to residual pain after treatment of CMC joint arthritis, using pain catastrophizing scale (PCS) and the Yatabe-Guilford (YG) personality test...

Intraneural ganglia are rare, benign cysts that form within the epineurium of the affected nerve. Patients present with features of compressive neuropathy, including numbness. We report a 74-year-old male patient with pain and numbness on his right thumb of 1-year duration. Magnetic resonance imaging revealed a cystic lesion with a possible scaphotrapezium-trapezoid joint connection. The articular branch was not identified during the surgery and decompression with excision of the cyst wall was done. A recurrence of the mass was noted 3 years later, but the patient was asymptomatic and no additional intervention was done...

Background: The aim of this study was to determine the feasibility of the chicken foot model for surgical trainees interested in practising the designing, harvesting and inset of locoregional flaps of the hand. Methods: A descriptive study was performed to demonstrate the technical aspects of harvesting four locoregional flaps in a chicken foot model: fingertip volar V-Y advancement flap, four-flap and five-flap Z-plasty, cross-finger flap and first dorsal metacarpal artery (FDMA) flap. The study was performed in a surgical training laboratory on non-live chicken feet...

Background: This multicenter retrospective study aimed to compare clinical outcomes and cost-effectiveness with bone substitutes on volar locking plate (VLP) fixation of unstable distal radial fractures (DRF) in the elderly. Methods: The data of 1,980 patients of ≥65 years of age who underwent surgery for the DRF with a VLP in 2015-2019 were extracted from a database (named TRON). Patients lost to follow-up or who received autologous bone grafting were excluded. The patients ( n = 1,735) were divided into the VLP fixation alone (Group VLA) and VLP fixation with bone substitutes (Group VLS)...

Osteonecrosis affecting the carpal bones is rare and is mostly seen in the lunate (Kienböck's disease). Osteonecrosis of the scaphoid (Preiser disease) is even rarer. There are only four individual case reports published on patients presenting with trapezium necrosis, none with previous history of corticosteroid injection. This case report is the first presentation of isolated trapezial necrosis in the setting of prior corticosteroid injection for thumb basilar arthritis. Level of Evidence: Level V (Therapeutic)...

Background: We aimed to evaluate the validity and reliability of the Persian version of the WOrk-Related Questionnaire for UPper extremity disorders (WORQ-UP) questionnaire in a working population with upper extremity musculoskeletal disorders. Methods: We enrolled 181 patients with upper extremity conditions to complete the Persian WORQ-UP. A total of 35 patients returned after 1 week to complete the questionnaire again. To test the construct validity, patients responded to the Persian Quick Disabilities of the Arm, Shoulder and Hand questionnaire (Quick-DASH) at the first visit...

Background: There are numerous flaps described for the treatment of fingertip amputation. Most flaps do not address the shortened nail resulting from amputation. Proximal nail fold (PNF) recession is a simple procedure that exposes the hidden portion of the nail and improves the aesthetic appearance of an amputated fingertip. The aim of this study is to measure the size and aesthetic outcomes of the nail following fingertip amputation in patients treated with PNF recession compared to those treated without PNF recession...

Closed rupture of the flexor digitorum profundus (FDP) tendon causes loss of flexion at the distal interphalangeal joint. Following trauma, these are known to present as avulsion fractures (Jersey finger) commonly in ring fingers. Traumatic tendon ruptures at the other flexor zones are seldom noted and are often missed. In this report, we present a rare case of closed traumatic tendon rupture of the long finger FDP at zone 2. Though it was missed initially, was confirmed with Magnetic Resonance Imaging and underwent successful reconstruction using an ipsilateral palmaris longus graft...

Intraosseous schwannomas are extremely rare and only a few cases involving the proximal phalanx and metacarpal of the hand have been reported. We report a patient with an intraosseous schwannoma of the distal phalanx. Radiographs showed lytic lesions in the bony cortex and enlarged soft shadows of the distal phalanx. The lesion was hyperintense to fat on T2-weighted magnetic resonance imaging (MRI) and strongly enhanced after gadolinium (Gd) administration. Surgical findings revealed that the tumour had developed from the palmar side of the distal phalanx and the medullary cavity was filled with a yellow tumour...

Background: Three-dimensional (3D) printing technology is increasingly commercially viable for pre-surgical planning, intraoperative templating, jig creation and customised implant manufacture. The challenging nature of scaphoid fracture and nonunion surgery make it an obvious target. The aim of this review is to determine the use of 3D printed technologies in the treatment of scaphoid fractures. Methods: This is a review of the Medline, Embase and Cochrane Library databases examining studies aimed at therapeutic use of 3D printing, also known as rapid prototyping or additive technology, in the treatment of scaphoid fractures...

We present a patient with Pacinian corpuscle hypertrophy and hyperplasia in the hand and discuss the diagnosis and treatment of this rare condition. A 46-year-old woman presented with radiating pain of the left middle finger. A strong Tinel-like sign was elicited between the index and middle fingers. The patient frequently used mobile phone, with the corner of the phone consistently applying pressure on the palm. The surgery was carried out under the microscope and two enlarged cystic lesions under the epineurium were found in the proper digital nerve...

Background: The coexistence of carpal tunnel syndrome (CTS) and trapeziometacarpal (TMC) osteoarthritis have been previously described. The influence of TMC osteoarthritis in the outcomes of CTS surgery is yet to be elucidated. The purpose of this study is to examine the prevalence of TMC osteoarthritis in patients who underwent open carpal tunnel release (OCTR) and to analyse the influence of osteoarthritis on the postoperative outcomes of CTS. Methods: We retrospectively reviewed 134 procedures on 113 patients who underwent OCTR between 2002 and 2017...
