BACKGROUND: Neurofibromatosis type 1 is a hereditary disease that can lead to pseudoarthrosis of various long bones. Rarely, pseudoarthrosis affects the forearm, and to the best of our knowledge, this is the first reported case of pseudarthrosis of the distal radius treated by this unique method. METHODS: We present a case of a 7-year-old male who underwent multiple operations to treat pseudoarthrosis of the distal radius. RESULTS: After failed conservative and operative fixation augmented with autologous iliac crest bone grafting, the patient underwent a successful double-barrel vascularized free fibula graft while preserving the physis of the distal radius...

BACKGROUND: No goniometric technique is both maximally convenient and completely accurate, although photogoniometry (ie, picture taking to facilitate digital angle measurement) shows promise in this regard. Our purpose was to test the feasibility and reliability of a photogoniometric protocol designed to measure wrist and digit range of motion in general. METHODS: Two independent observers examined a sample of joints in both normal and abnormal hands according to a photogoniometric protocol...

BACKGROUND: Scaphoid fractures progress to nonunion rates of up to 15% when non-displaced, and are even more frequent when the fracture is displaced. Standard treatment in these cases is surgery; however, individuals unable to undergo this operation, or for those who wish to try more conservative measures, there may be benefit from nonoperative options. Of these, low-intensity pulsed ultrasound (LIPUS) has been shown to improve fracture nonunion healing. The purpose of this study was to perform a comprehensive meta-analysis of relevant literature to determine success of the use of LIPUS for treatment of scaphoid nonunion...

BACKGROUND: Amyloidosis affecting peripheral nerve is usually seen in primary amyloidosis. METHODS: We are reporting on the case of a 74-year-old man with a 16-month history of progressive left radial nerve paralysis. Perioperative imaging detected an enlarged radial nerve in the middle-distal part of the arm. The patient had an antecedent of amyloid deposits in the lung. RESULTS: A radial nerve amyloidosis was suspected and confirmed with a biopsy assisted by ultrasonography, resulting in a secondary amyloidosis form...

Michael Canaan Prater, Brian A Janz
BACKGROUND: Lymphangiomas are benign lymphatic vessel hamartomas typically found in the skin or subcutaneous tissue of the head and neck. Although mostly seen in a congenital context, acquired forms have been reported. By contrast, cavernous hemangiomas are benign hamartomas of endothelial origin. They can arise anywhere in the body, but are typically described as arising from the central nervous system. METHODS: We report the case of a young patient who developed a mixed lymphangioma and cavernous hemangioma within the ulnar nerve...

BACKGROUND: Current management of brachial plexus injuries includes nerve grafts and nerve transfers. However, in cases of late presentation or pan plexus injuries, free functional muscle transfers are an option to restore function. The purpose of our study was to describe and evaluate the rectus abdominis motor nerves histomorphologically and functionally as a donor nerve option for free functional muscle transfer for the reconstruction of brachial plexus injuries. METHODS: High intercostal, rectus abdominis, thoracodorsal, and medial pectoral nerves were harvested for histomorphometric analysis from 4 cadavers from levels T3-8...

BACKGROUND: Angiosarcoma is a rare but aggressive malignancy with a high predilection for the head and neck. There have been few case reports of the development of angiosarcoma in a nonfunctional arteriovenous fistula in a hemodialysis patient. METHODS: After institutional review board approval, a retrospective chart analysis is conducted to present the case of a patient who received plastic surgical treatment at our hospital. RESULTS: We present the case of a 44-year-old male who presented with ischemic changes and paresthesias of the upper extremity associated with the development of angiosarcoma in an arteriovenous fistula...

BACKGROUND: Four-corner fusion has been shown to be a reliable option of treatment of wrist arthritis, but there is no consensus about which implant and surgical procedure should be used in the arthrodesis. The present study aimed to describe a surgical technique using 2 crossed screws as implants, inserted in a retrograde manner, and to demonstrate preliminary results of the use of the technique. METHODS: A retrospective study was conducted using medical records and imaging tests (radiographs and computed tomography) of all 15 patients who underwent a standardized 4-corner fusion technique, between December 2011 and July 2015, in the Department of Hand Surgery of Instituto Nacional de Traumatologia e Ortopedia (INTO), Rio de Janeiro, Brazil...

Israel Berger, Isak Goodwin, Gregory M Buncke
BACKGROUND: Fluoroquinolone use has been known to be associated with tendinopathy and tendon rupture for over 30 years. Hand and wrist involvement has been reported rarely, yet without early recognition and withdrawal of the fluoroquinolone, there is potential for significant morbidity. METHODS: We searched Medline using a comprehensive search strategy for fluoroquinolones and tendinopathy of the hand and wrist, and provide a case report of a possible levofloxacin-related tendon rupture in a patient with a previous mutilating hand injury...

BACKGROUND: The relationship of routinely measured grip and motion measures may be related to hand dexterity. This has not yet been thoroughly examined following a distal radius fracture (DRF). The purpose of this study was to investigate if impairments in range of motion (ROM) and grip strength predict hand dexterity 6 months following a DRF. METHODS: Patients with DRFs were recruited from a specialized hand clinic. Hand grip was assessed with a J-Tech dynamometer; ROM was measured using standard landmarks and a manual goniometer...

BACKGROUND: The Conventus Distal Radius System (DRS) is an intramedullary fixation scaffold inserted into the lateral aspect of the distal radius. The purpose of this study was to identify insertion site anatomy to illustrate risks associated with the minimally invasive nature of radial-sided implant application. METHODS: Ten cadavers were utilized. Using fluoroscopy, the 1.1-mm Kirschner wire and template was introduced per manufacturer's guidelines, access guide assembled, and dissection carried out to the superficial radial nerve (SRN) with preservation of the native location...

Gregory I Pace, Connor L Zale, David Gendelberg, Kenneth F Taylor
BACKGROUND: Carpal tunnel surgery is the most common surgical procedure performed on the hand. Although complications are rare, recurrent or persistent carpal tunnel syndrome can be a significant problem after primary decompression. Various procedures have been described for the treatment of these patients including repeat decompression and hypothenar fat pad transposition. The purpose of this study is to compare the outcomes of patients undergoing revision carpal tunnel decompression with and without hypothenar fat pad transposition...

Background: Perilunate fracture dislocations are often associated with fractures of the distal pole of the scaphoid or the proximal pole of the capitate. However, the combination of perilunate dislocation with multiple carpal fractures and associated scaphocapitate syndrome is very rare. Methods: We report a unique case of scaphocapitate fracture syndrome with perilunate dislocation and fracture of the hamate resulting from a high-energy injury to the wrist during a dirt-bike competition. Results: Open reduction and internal fixation of the scaphoid fracture with a 3...
