Background: Percutaneous Kirschner wire (K-wire) fixation of hand and wrist fractures is a common trauma procedure, yet there remains little consensus on the best management of wires postoperatively. If wire's ends are left external to the skin, it remains unknown which dressing regimen best reduces infection risk. We felt that a systematic review was required to assess the current consensus on this question within the published literature. Methods: An electronic search was carried out across multiple databases...

Lipofibromatous hamartoma (LFH) of the median nerve is a rare condition in the hand and often remains asymptomatic for a significant period. MRI imaging can reveal unique tumour characteristics; however, the definitive diagnosis is confirmed through a tissue biopsy. In this report, a 38-year-old male presented with a gradually growing mass on his right hand. Physical examination revealed a large soft tissue mass extending from the thenar area to the wrist, causing compression of the median nerve. MRI confirmed the presence of a distinct soft tissue mass on the volar side of the hand...

Surgical reconstruction can restore length and function, but cannot adequately resolve the problem of disfigurement. Prosthetic fitting can play a complementary role in enhancing the aesthetic outcomes post reconstruction. However, complex reconstruction involving flaps coupled with the surgical imperative for limb length preservation can lead to outcomes where the reconstructed stumps are challenging to fit with prosthesis. This article describes how prosthetic fitting was tackled in a case of a triple-digit amputation after reconstruction that presented with finger stumps that were bulky, long and stiff in extension contracture, compounded by the presence of substantive scar tissues...

Background: Extra-articular proximal phalanx base fractures are common in adults and can lead to permanent finger stiffness and joint contractures. The purpose of this review is to summarise the evidence for operative and non-operative management of this fracture type. Methods: The MedLine, Embase, PubMed, Scopus and Cochrane Library databases were searched using the following key terms: 'proximal phalanx', 'base', 'fracture', 'repair' and 'fixation'. A total of 2,889 unique records were extracted. All studies with primary data on the management of extra-articular proximal phalangeal base fractures in adults were included for initial review...

Background: Dynamic forces acting on the transverse carpal ligament (TCL) may influence the mechanics of the carpal tunnel (CT), thus affecting the occurrence of CT syndrome (CTS). Previous studies demonstrated an association between muscle overlying the CT and the diagnosis of CTS. Understanding the location of insertion/origin of the thenar musculature will allow mechanical analysis of the forces applied to the TCL during performance of individual tasks. Our purpose was to determine the location of muscle overlying the CT on magnetic resonance imaging (MRI) in CTS and controls...

Background: Despite the good clinical results in the treatment of Kienböck disease with distal radius core decompression, a radiological progression to a certain degree in the long-term follow-up is possible. Is there a negative correlation between the clinical improvement of the patients and the radiological progression? Methods: We retrospectively reviewed the radiological and clinical results of 24 patients (mean age: 38 years; 10 women) treated with core decompression for Kienböck disease. The mean follow-up was 10 years...

Background: This study introduces a novel method for the management of closed metacarpal neck fractures. Kirschner wires (K-wire) are introduced in a retrograde and the wires withdrawn through skin proximally at the base of the metacarpal. The fracture is reduced using traction and the reduction is maintained by antegrade advancement of the K-wires. The aim of this study is to report the outcomes of this technique. Methods: A total of 36 patients with severely angulated closed metacarpal neck fractures underwent reduction and fixation using this novel method from January 2017 to December 2020 in centres in Ireland and Saudi Arabia...

Background: This study aimed to evaluate our preliminary results and experience with the arthroscopic dorsal ligamentocapsulodesis in managing occult dorsal wrist ganglion cysts (ODGCs) associated with scapholunate (SL) instability. Methods: All patients who underwent arthroscopic dorsal ligamentocapsulodesis due to an ODGC with concomitant SL ligament tear were retrospectively reviewed. In addition to demographic data and length of follow-up, outcomes data that included range of motion, grip strength, modified Mayo wrist score (MMWS), complications and radiographs were collected...

Forearm deformities are often seen in children with severe birth brachial plexus palsy (BBPP). They may be either a supination or a pronation deformity and both hinder normal use of the hand and parents often request for corrective surgery. However, the correction of these deformities can be challenging due to a paucity of options. Also, there is less information in literature on the management of forearm deformities in BBPP compared to the information with regard to nerve surgery or correction of shoulder deformities...

Background: Total wrist replacement (TWR) is rarely done in the Asia-Pacific region. The aim of this study is to report the surgical outcomes and experience of TWR in patients with advanced arthritis. Methods: This is a retrospective review of all TWR patients in the Department of Orthopaedics and Traumatology, Prince of Wales Hospital, Hong Kong, which is a university tertiary centre, from January 2004 to March 2023. Recorded demographic parameters include gender, age upon surgery, pathology, types of implants and follow-up period...

Background: A flexion contracture (FC) of the proximal interphalangeal (PIP) joint can have a profound negative influence on daily activity. The outcomes of surgical release of the PIP joint in literature are based on small sample size studies done several decades ago. The aim of this study is to report the outcomes of surgical treatment for post-traumatic FC of the PIP joint and to identify factors that affect these outcomes. Methods: This single institute retrospective study included patients from 2000 to 2020...

Background: Endoscopic carpal tunnel release (ECTR) is a less invasive procedure but has a higher risk of complications. We analysed ECTR cases dividing them into three periods according to a single surgeon's experience when the ECTR was performed: the initial, midterm and late period. Cases of iatrogenically induced median nerve injuries that occurred after ECTR were then noted and evaluated. Methods: We reviewed 195 ECTRs done with the 2-portal technique and divided the patients into three groups according to periods of when ECTR was done...

Dupuytren disease is a common benign fibromatosis of the palmar and finger fascia caused by pathological cord formation. As both the retrovascular and lateral cords are jointly responsible for the flexion contracture of the distal interphalangeal (DIP) joint, isolated DIP joint contracture caused by Dupuytren disease is rare. We present a 34-year-old right-hand-dominant male patient with a 6-month history of an isolated DIP joint flexion contracture in the right ring finger due to Dupuytren disease. Surgical fasciotomy of the retrovascular cord improved the contracture without adverse events...

Introduction: Dorsal fracture dislocations (DFD) of the proximal interphalangeal joint (PIPJ) are challenging fractures. A palmar surgical approach and plate fixation has a high complication rate, including flexor contractions, reduction of range of motion (ROM) and secondary need for plate removal. Methods: We use the flexor tendon pulleys to cover the mini plate with the assumption that it may reduce the adhesion between the mini plates and the tendons and reduce postoperative complications. We present the outcomes of using this technique in eight patients...

A 60-year-old woman presented functional deficit of the index finger flexor digitorum profundus (FDP) tendon after shoulder arthroscopic rotator cuff repair. As no recovery was observed for 10 months, we conducted an operative exploration of the median nerve and the anterior interosseous nerve, followed by an external neurolysis. The patient recovered FDP function 4.5 months after the second operation. In a patient with persistent isolated FDP dysfunction after shoulder arthroscopy, operative exploration and external neurolysis could facilitate functional recovery...

Background: Replantation of digital tip amputations, especially Allen III and IV, is challenging for hand surgeons as it requires a high level of microsurgical expertise and fine instruments. The graft repositioning over flap (GRF) technique is a simple and reliable procedure that provides length, sensation and nail growth and GRF has become popular in the last few years. The aim of this study is to report the short-term outcomes of the GRF technique. Methods: This is a prospective study of all patients who underwent a GRF reconstruction for Allen III and IV digital amputations at our hospital over a 12-month period...

Background: We treated distal radius fractures (DRFs) beyond the watershed line without fracture of the lunate volar rim using a volar locking plate (VLP) and report the radiological and clinical outcomes at least 3 years after surgery. Methods: In 41 consecutive patients between January 2012 and August 2017, the fragment was composed of the radial styloid process (distal to the watershed line) and the lunate volar rim was intact. We evaluated demographic factors, radiological features and radiological/clinical outcomes at the final follow-up...

Background: In brachial plexus surgery, a key focus is restoring shoulder abduction through spinal accessory nerve (SAN) to suprascapular nerve (SSN) transfer using either the anterior or posterior approach. However, no published randomised control trials have directly compared their outcomes to date. Therefore, our study aims to assess motor outcomes for both approaches. Methods: This study comprises two groups of patients. Group A: anterior approach (29 patients), Group B: Posterior approach (29 patients)...

Background: The stent technique of microvascular anastomosis, in which a stent is placed in the vessel before creating the anastomosis, is useful for accurate anastomosis formation, but the manipulation involved in stent insertion into the vessel and withdrawal from the anastomosis still poses problems. In this study, a silastic stent containing a copper wire-bent in an L-shape was designed and its utility in microvascular anastomosis was investigated in rats. Methods: Eighty end-to-end anastomosis procedures of the right femoral artery and vein were performed in rats...
