Role of platelet rich plasma in fracture non-union of scaphoid - Case series.

This case series of 4 patients was studied at Queen Mary Hospital, Hong Kong from 2007 to 2011 to evaluate the clinical and radiological outcome of scaphoid fracture non-union treated with Open reduction and internal fixation ORIF supplemented with Bone Graft (BG) from iliac crest and Platelet Rich Plasma PRP. The purpose was to achieve union with pain free adequate range of movement. Patients presenting with scaphoid fracture non-union were included in our study.

The status of triangular fibrocartilage complex after the union of distal radius fractures with internal plate fixation.

Purpose: Distal radius fractures are associated with a high incidence of triangular fibrocartilage complex (TFCC) tears. This study aims to evaluate the status of TFCC after the healing of distal radius fractures, and its clinical significance.

Methods: Wrist arthroscopies were performed on 43 distal radius fractures, with an average age of 54 years old.

New technique: tendon interposition arthroplasty in Distal Interphalangeal Joint arthritis in Chinese population - New horizon for treatment.

Objective: To evaluate the clinical outcome of managing distal inter-phalangeal joint arthritis by using excisional arthroplasties with soft-tissue interposition to provide pain-free joint with adequate range of motion and preserving the bone stock.

Methods: The case series was conducted at Queen Mary Hospital, Hong Kong from 2013 to 2015 and comprised patients with distal inter-phalangeal joint arthritis. Excisional arthroplasty was performed for all patients.

Fatal bilateral lower-limb deep vein thrombosis and pulmonary embolism following single digit replantation.

Venous thromboembolism in hand surgery is rare. There is no report in the literature on postoperative mortality from venous thromboembolism following microsurgery in upper limbs. We report the case of a 56-year-old Chinese man who died from pulmonary embolism as a result of bilateral lower-limb deep vein thrombosis following prolonged surgery under general anaesthesia after replantation of a finger.

Does aging matter? The efficacy of carpal tunnel release in the elderly.

Open release remains the gold standard in the treatment of carpal tunnel syndrome in cases where conservative treatment fails. However, the efficacy of carpal tunnel release in the elderly has been debated in the literature throughout the years. This review aims to review the current evidence pertaining to the efficacy of carpal tunnel release in the elderly.

Current management of hand enchondroma: a review.

Enchondromas are benign bone tumours originating from cartilages. It is mainly discovered incidentally in radiographs or due to symptoms like pathological fracture or pain. Conservative treatment through regular check-up and surgical excision using curettage are the two major treatment methods for enchondromas.

A rare combination: locked volar distal radio-ulnar joint dislocation with isolated volar capsule rupture.

Distal Radioulnar Joint (DRUJ) dislocation is a commonly missed injury. A high clinical suspicion is required as the dislocation may not be obvious in the conventional views of radiographs. Volar DRUJ dislocations are far less common than the dorsal ones.

A new building block: costo-osteochondral graft for intra-articular incongruity after distal radius fracture.

Even with the invention of locking plates, intra-articular fractures of distal radius with extreme comminution remain a challenge for orthopaedic surgeons. Osteochondral graft is a potential choice to reconstruct the articular defect. We report a patient who had a fracture of distal radius with costo-osteochondral graft for articular reconstruction which has not yet been described in the English literature.

Current management of acute scaphoid fractures: a review.

The aim of this review was to present currently available evidence on the management of acute scaphoid fractures. Acute scaphoid fractures are usually diagnosed by a combination of history, physical examination, and radiography. However, in many patients scaphoid fractures are still missed.

Peak load resistance of the JuggerKnot™ soft anchor technique compared with other common fixation techniques for large mallet finger fractures.

Introduction: To identify the strongest peak load resistance among four mallet finger fracture fixation methods (Kirschner wire, pull-out wire, tension-band wiring and the JuggerKnot™ (Biomet) soft anchor fixation).

Methods: Fixation techniques were assigned among 24 specimens from six cadaveric human hands in a randomized block fashion. Peak load resistance was tested at 30°, 45° and 60° of flexion of the distal interphalangeal joint.

Schwannoma in the upper limbs.

Schwannomas are the commonest tumours of peripheral nerves. Despite the classical description that schwannomas are well encapsulated and can be completely enucleated during excision, a portion of them have fascicular involvement and could not be completely shelled out. A retrospective review for 8 patients was carried out over 10 years.

Where is the Lesion? Glomus Tumours of the Hand.

Glomus tumours are vascular hamartomas that are commonly found in the hand, particularly the subungual region. They appear as solitary or multiple tumours, and often present as a bluish discoloration of the nail plate. Different diagnostic tests are outlined, as well as imaging studies such as magnetic resonance imaging and ultrasound.

Ten-year results using a dynamic treatment for proximal phalangeal fractures of the hands.

Fractures of the proximal phalanges of the hands can be treated by many methods. With surgical intervention, a loss in proximal interphalangeal joint movement is common. Using the stabilizing effect of the zancolli complex-metacarpophalangeal retention apparatus and an external device such as a thermoplastic metacarpophalangeal block splint, proximal phalangeal fractures can be stabilized in terms of axis, length, and rotation.

The beauty of stability: distal radioulnar joint stability in arthroscopic triangular fibrocartilage complex repair.

The triangular fibrocartilage complex (TFCC) has an important role in the stability of the distal radioulnar joint (DRUJ) stability. We designed a new method of TFCC tear repair that has satisfactory post-operative DRUJ stability. From May 2004 to August 2010, 14 patients who underwent this operation were reviewed.

Review on mallet finger treatment.

Mallet finger is a common injury involving either an extensor tendon rupture at its insertion or an avulsion fracture involving the insertion of the terminal extensor tendon. It is usually caused by a forceful blow to the tip of the finger causing sudden flexion or a hyperextension injury. Fracture at the dorsal aspect of the base of the distal phalanx is commonly associated with palmar subluxation of the distal phalanx.

Mycobacterium marinum infection of the hand and wrist.

Purpose: To review records of 166 patients who underwent treatment for Mycobacterium marinum tenosynovitis of the hand and wrist to identify factors associated with functional outcome.

Methods: Records of 97 men and 69 women aged 13 to 85 (mean, 50) years who underwent treatment for suspected M marinum tenosynovitis of the hand and wrist were retrospectively reviewed. All underwent open biopsy; synovectomy was performed when florid synovitis was present.

Hand infection in diabetic patients.

The diabetic hand infection is less reported in the literature. Therefore, it is easily ignored and underestimated resulting in increased morbidity among the diabetic population. Diabetic hand is a rapid in progression, extensive and severe tissue destruction.

Lateral tibial condyle reconstruction by pedicled vascularized fibular head graft: long-term result.

The technique of pedicled vascularized fibular graft for lateral tibial condyle reconstruction after en bloc resection of aggressive giant cell tumours was described by SP Chow et al. Early follow-up of two patients was presented in 1986. We present the 25 years follow-up of one patient with a literature review of alternative present day treatment options.

Long term results of matched hemiresection interposition arthroplasty for DRUJ arthritis in rheumatoid patients.

Introduction: The distal radioulnar joint (DRUJ) is commonly affected in rheumatoid arthritis and is associated with significant functional morbidity. The aim of our study is to review our results with matched hemi-resection interposition arthroplasty in patients with DRUJ arthritis.

Methods: This was a retrospective study of 39 patients with 51 wrists that were treated at Queen Mary Hospital in Hong Kong from 1989 to 2007.

Mycobacterium marinum infection of the deep structures of the hand and wrist: 25 years of experience.

Mycobacterium marinum infection could have various presentations, from superficial skin infection to deep structure destruction. The prognosis is relatively poor when deep structure is involved as it is more destructive. The prognosis is even worse when operation is required.

Multiple triggering in a girl with Ehlers-Danlos syndrome: case report.

We report a case of multiple triggering associated with Ehlers-Danlos syndrome. We postulate that the propensity for tendon degeneration in Ehlers-Danlos syndrome coupled with repetitive microtrauma might lead to fraying of the tendon fibers and, consequently, triggering. Indeed, in our case, debridement of the tendons rather than resection of A1 pulley resulted in a good long-term functional outcome 2 years after surgery.

Review article: Mycobacterium marinum infection of the hand and wrist.

Misdiagnosis and delayed treatment of Mycobacterium marinum infection is common because of its diverse manifestations. This leads to inappropriate use of antimicrobials, extension of the infection from the skin to the tenosynovium, and a poor prognosis (loss of tendons and prolonged immobilisation, secondary to multiple debridements and joint contractures). Clinicians should be aware of this type of infection, especially in subjects at risk (fishermen and aquarium enthusiasts), and those with a history of trauma coupled with exposure to water or marine life.
