Composite tissue allotransplantation holds great promise for upper extremity reconstruction but is limited by donor part availability. Cryopreservation may increase the availability of donor parts and even reduce antigenicity. The purpose of the study was to evaluate the viability of cryopreserved composite tissues and to demonstrate the feasibility of microvascular isotransplantation of cryopreserved...
A 1-year-old boy presented to us with congenital inability to flex his elbow. He had bilaterally absent biceps brachii and brachialis muscles, a rare condition. We performed pedicle latissimus dorsi musculocutaneous flaps to the left and right volar upper arm at 21 and 24 months of age, respectively, to create elbow flexors. By 4 years of age, he had excellent elbow flexion bilaterally with strength...
Introduction Intra-articular distal radius fractures with volar and dorsal comminution present a special challenge to the hand surgeon. Methods Ten patients formed the study cohort. All plates were low profile and stainless steel. Radiographic parameters, range of motion, and strength compared to the uninjured side were recorded. Functional outcome was evaluated by Disabilities of the Arm, Shoulder...
Purpose Fixed-angle devices have been a major advancement in orthopedic fracture care and have become an attractive option for fixation of distal radius fractures. Several volar locking plates exist, but there is insufficient literature comparing the strengths of these plates. This study compares the biomechanical strength of two popular volar locking plate systems (Synthes LCP and Hand Innovations...
Twenty-one patients with rheumatoid arthritis who underwent Swanson metacarpophalangeal (MP) arthroplasty from 1994 to 1999 were assessed for active flexion of individual MP joints an average of 59 months (range 27–114 months) postoperative. Published articles of Swanson MP arthroplasty were reviewed. Experienced hand surgeons were surveyed regarding outcomes of metacarpophalangeal arthroplasty. The...
Subungual metastasis as a presenting feature of lung adenocarcinoma is rare and may be confused with a benign inflammatory disorder of the nail unit with subsequent diagnostic and management delay. We discuss the case of a 46-year-old man with a subungual metastasis as a presenting feature of lung adenocarcinoma.
Immobilization protocols for nondisplaced scaphoid fractures have included the elbow, wrist, and thumb. This study attempts to demonstrate whether or not immobilization of the thumb makes a difference in preventing motion at the scaphoid fracture site. Using six fresh frozen forearm specimens, a transverse waist scaphoid fracture was created through a dorsal approach. Metallic markers were imbedded...
A case of unusual displacement in a finger, with an avulsion fragment from the dorsal metacarpal head of the finger displaced in the palmar direction under the volar plate is described. An 18-year-old woman presented with complaint of difficulty flexing the metacarpophalangeal (MP) joint of the right little finger after a fall onto the outstretched hand. Three-dimensional computed tomography (CT)...
In this pilot study, hypertonic dextrose solution was used to induce fibrosis of the subsynovial connective tissue (SSCT) and create an animal model of potential use in the study of carpal tunnel syndrome (CTS). The SSCT of the carpal tunnel in 15 New Zealand white rabbits were injected with 0.05 ml of 10% dextrose solution in 1 paw and 0.05 ml of saline in the contralateral paw, to serve as a control...
A unique case of combined intrauterine vascular insufficiency and complete brachial plexus palsy is described in a newborn delivered by cesarean section. Intrauterine vascular insufficiency resulted in a right below elbow amputation at 3 weeks of age. Amputation length was preserved after a pedicled thoracoabdominal flap. Function of the C5, C6, and C7 nerve roots returned to normal by 3 months of...
Epidemiological studies conducted largely in northern Europe and Australia have shown that Dupuytren’s disease is less common in women, with reported overall male-to-female ratios ranging from 3:1 to 9.5:1. Epidemiological data from other countries cannot be extrapolated to the modern U.S. population due to genetic and environmental differences between populations. The aim of this study was to determine...
Introduction The purpose of this paper is to evaluate the Silver Bullet Wound Closure Device (SBWCD, Boehringer Laboratories, Norristown, PA), a new device for delayed primary closure of fasciotomy wounds. Materials and Methods A retrospective review was performed over a period of 36 months of all patients with an upper extremity fasciotomy that could not be closed primarily. Cases that underwent...
A change in the practice of a single surgeon provided an opportunity for retrospective comparison of comparable cohorts treated with percutaneous fixation (17 patients) or a volar plate and screws (23 patients) an average of 30 months after surgery. The final evaluation was performed according to the Gartland and Werley and Mayo rating systems and the DASH questionnaire. There were no significant...
There are few objective staging systems to assess severity of Dupuytren’s disease (DD). Previous methods to assess severity of DD were based primarily on the degree of contracture of an affected digit measured using a goniometer. Nonetheless, this method of assessment alone may be incomplete, and other factors should be considered. White (n = 92) patients diagnosed with DD from northwest of England...
Introduction We retrospectively compared the outcomes of open reduction and internal fixation (ORIF) with volar locking plate versus standard external fixation and percutaneous pinning in treating similar unstable distal radius fractures with a minimum 2-year follow-up. Methods The ORIF group included 41 patients with an average follow-up of 29 months. The external fixation group comprised 14 patients...
The purpose of this study was to compare the biomechanical properties of four volar fixed-angle fracture fixation plate designs in a novel sawbones model as well as in cadavers. Four volar fixed angle plating systems (Hand Innovations DVR-A, Avanta SCS/V, Wright Medical Lo-Con VLS, and Synthes stainless volar locking) were tested on sawbones models using an osteotomy gap model to simulate a distal...
The current gold standard for the diagnosis and staging of hand–arm vibration syndrome (HAVS) is the Stockholm workshop scale, which is subjective and relies on the patient’s recalling ability and honesty. Therefore, great potentials exist for diagnostic and staging errors. The purpose of this study is to determine if objective serum tests, such as levels of soluble thrombomodulin (sTM) and soluble...
Background The ideal treatment of nonunion of the scaphoid remains unresolved and controversial. It was hypothesized that scaphoid nonunion could be treated successfully using a closed-wedge osteotomy of the distal radius which reduces the inclination of the joint surface and decreases the pressure between the radial and scaphoid surfaces with a reduction of the force applied by the styloid process...
