PURPOSE: The aim of this study was to evaluate the functional, clinical, and radiological outcome 10 years after distal scaphoid fractures. METHODS: From a prospective epidemiological study on posttraumatic radial-sided wrist pain, we evaluated 41 cases of distal scaphoid fractures. All cases had been treated nonsurgically in a thumb spica cast. Patients were examined using radiographs, magnetic resonance imaging and computed tomography at the time of injury and with computed tomography after a median of 10 years (range, 8-11 years)...

PURPOSE: The objective of this study was to characterize the morphology of the radial head and design population-based anatomical and patient-specific radial head implants. METHODS: Computed tomography (CT) images of 50 normal cadaveric upper extremities (34 male, 16 female) were obtained using a 64-slice CT scanner. Surface models were ellipse-fitted and characterized. Using an intersurface distance mapping approach, the surface geometry of the population-based anatomical design (PB-An), 3 distinct patient-specific designs, and an existing axisymmetrical implant (Com-Axi) were compared with the native radial head and the overall surface mismatch was measured...

PURPOSE: In pediatric extremity fractures treated nonsurgically, maintaining reduction can be difficult in obese children owing to the larger soft tissue envelope. The purpose of this study was to investigate the relationship between obesity and failure of nonsurgical management of pediatric both-bone forearm fractures. METHODS: We conducted a retrospective review of 129 skeletally immature patients older than 2 years who received nonsurgical treatment for closed radius and ulna shaft fractures at a level I pediatric trauma center between 2011 and 2014...

#6
Matthew J St John, David Mitten, Warren C Hammert
PURPOSE: The Patient Reported Outcome Measurement Information System (PROMIS), developed by the National Institutes of Health, utilizes a health domain related to Pain Interference (PI). We evaluated this domain and its association with physical function (as determined by PROMIS Physical Function [PF]), administered as a computer adaptive test (CAT), and secondarily its association to a numerical 0 to 10 pain score. Our null hypothesis was that PI, as measured by CAT, has no correlation to PF and thus, there is no difference between comparisons of numerical pain scores and PROMIS PF...

PURPOSE: Several surgical stabilization techniques have been described to address pathological subluxation of the extensor carpi ulnaris (ECU) tendon, with no comparative data available. This study compares ECU stability after subsheath reconstruction, with and without ulnar groove deepening, to stability with an intact subsheath in a cadaveric model. METHODS: Position of the ECU tendon relative to the ulnar groove was measured in 5 human cadaveric specimens with the subsheath intact, sectioned, and after 3 reconstruction scenarios: reconstructed, reconstructed with ulnar groove deepened, and ulnar groove deepened with subsheath sectioned...

David W Meister, Krystle A Hearns, Michelle G Carlson
PURPOSE: To evaluate the diagnostic utility of scaphoid dorsal subluxation on magnetic resonance imaging (MRI) as a predictor of scapholunate interosseous ligament (SLIL) tears and compare this with radiographic findings. METHODS: Thirty-six MRIs were retrospectively reviewed: 18 with known operative findings of complete Geissler IV SLIL tears that were surgically repaired, and 18 MRIs performed for ulnar-sided wrist pain but no SLIL tear. Dorsal subluxation of the scaphoid was measured on the sagittal MRI cut, which demonstrated the maximum subluxation...

#10
REVIEW
Eugene T Ek, Kemble Wang
Surgical treatment of ultrasmall proximal pole scaphoid fractures poses a number of challenges. The fragment may be too small to fix with conventional headless screw fixation owing to the high risk of fragmentation upon insertion. However, excision of the fragment risks compromising the scapholunate ligament complex and also exposes the radioscaphoid joint to potential degenerative changes. Under these circumstances, we describe the use of bioabsorbable osteochondral fixation nails that allows stable low-profile fixation while minimizing the risk of fracturing the proximal pole...

REVIEW
Anais Legrand, Yoav Kaufman, Chao Long, Paige M Fox
Tendon injuries are encountered after major and minor hand trauma. Despite meticulous repair technique, adhesion formation can occur, limiting recovery. Although a great deal of progress has been made toward understanding the mechanism of tendon healing and adhesions, clinically applicable solutions to prevent adhesions remain elusive. The goal of this paper is to review the most recent literature relating to the tendon healing and adhesion prevention.

PURPOSE: Three-dimensional planning based on computed tomography images of the malunited and the mirrored contralateral forearm allows preoperative simulations of corrective osteotomies, the fabrication of patient-specific osteotomy guides, and custom-made 3-dimensional printed titanium plates. This study aims to assess the precision and clinical outcome of this technique. METHODS: This was a prospective pilot study with 5 consecutive patients. The mean age at initial injury was 11 years (range, 4-16 years), and the mean interval from the time of injury to the time of corrective surgery was 32 months (range, 7-107 months)...

Alexander Bitzer, Edward F McCarthy, Carol D Morris
Chordomas are low-grade malignant tumors that are locally aggressive and have the potential to metastasize. They most often occur in the sacrococcygeal and spheno-occipital portions of the vertebral column. Morphologically similar tumors have been found outside the axial skeleton and are referred to as extra-axial chordomas. Several case reports have described the radiologic, microscopic, and immunologic profiles of these tumors and their similarities to axial chordomas. The authors report a 24-year-old man who presented with a mass in his left hand and underwent surgical excision...

REVIEW
Thomas J Christensen, Shefali A Samant, Alexander Y Shin
All metals implanted into a biological system undergo some degree of corrosion depending upon its composition. The electrochemical process of corrosion produces free metal ions, which may activate the host's immune system through a variety of mechanisms. Whereas dermal metal hypersensitivity is common, affecting 10% to 15% of the population, the immune reaction from implanted metals is much less common (< 0.1%), but has been associated with metal allergy and hypersensitivity producing a multitude of patient symptoms...

REVIEW
Mohammed M Al-Qattan
The classic donor motor units for opponensplasty are the flexor digitorum superficialis, the extensor indicis proprius, the palmaris longus, and the abductor digiti minimi. Occasionally, all classic donor motor units are not available for the opponensplasty; a review of the literature revealed that the flexor carpi ulnaris opponensplasty has not been previously described. The surgical technique of the split flexor carpi ulnaris opponensplasty is described in the current paper along with a clinical example...

Infection with Mycobacterium marinum is often difficult to diagnose. Infection with M. marinum in the upper extremity may involve the tendon sheaths, producing clinical manifestations such as tenosynovitis and symptoms of carpal tunnel syndrome. We report 3 cases of M. marinum infection of the hand associated with carpal tunnel syndrome during an outbreak in New York City's Chinatown. A combination of carpal tunnel release, flexor tenosynovectomy, and appropriate antibiotics yielded complete resolution of symptoms in all cases...

Eosinophilic myositis is a rare disorder in which eosinophils infiltrate muscle and supporting connective tissue structures. The disorder can be localized or diffuse, and it may be associated with various systemic features resembling autoimmune disease. Focal eosinophilic myositis is the most limited form of eosinophilic myositis, for which muscle involvement is generally limited to the lower extremity. We report on a rare case of focal eosinophilic myositis of the interosseous muscles of the hand, which presented as a refractory, pyogenic hand infection...
