Predictors of scar pain after open carpal tunnel release

Purpose: To identify the predictors of scar pain after open carpal tunnel release (CTR). Methods: We enrolled 83 patients with idiopathic carpal tunnel syndrome treated by open CTR. All patients completed the Brigham and Women's (Boston) carpal tunnel questionnaire (BCTQ) preoperatively. We assessed levels of depression preoperatively using the Center for the Epidemiological Study of Depression (CES-D) scale, and pain anxiety using the Pain Anxiety Symptoms Scale. At 3 months after surgery, patients were asked to self-assess treatment satisfaction and scar pain using a 10-point ordinal scale and to complete the BCTQ. Results: The mean BCTQ-symptom (BCTQ-S) score decreased significantly from 2.7 ± 1.1 preoperatively to 1.6 ± 1.0 at 3 months postoperatively, and mean BCTQ-function score decreased significantly from 2.4 ± 1.1 to 1.4 ± 1.0. Overall, scar pain intensity at 3 months postoperatively ranged from 0 to 8 (mean, 2.4 ± 2.2), and overall satisfaction ranged from 2 to 10 (mean, 7.6 ± 2.6). The intensity of the scar pain was significantly correlated with the CES-D scale and BCTQ-S. Multivariable regression analysis showed that depression, assessed using the CES-D scale, and postoperative symptoms, assessed using the BCTQ-S, predicted scar pain intensity, which accounted for 38% of scar pain intensity variance. Conclusions: Depression score and postoperative symptoms predicted scar pain intensity after open CTR. However, the most important contributor to scar pain intensity variance remains unidentified.

Use of standard and anatomic-tilt lateral X-rays to determine distal radius volar angulation

Purpose: To determine the reliability of measurements of distal radius volar tilt using either standard lateral or anatomic tilt lateral (ATL) radiographs, and to compare the mean values obtained using each radiographic method. Methods: We obtained standard and 23° ATL plain radiographs of the distal radii of 20 patients with a distal radius fracture treated with a volar locking plate, and of 20 healthy individuals without a history of fracture of the wrist. Three orthopedic surgeons measured volar tilt twice with an interval of 4 weeks. We analyzed intraobserver and interobserver reliability and compared intraobserver means of volar tilts obtained using standard and ATL radiographs. Results: The volar tilts measured using ATL radiographs in patients and healthy controls showed moderate to excellent intraobserver and interobserver reliability, whereas those determined using standard lateral radiographs showed poor to moderate intraobserver and interobserver reliability in patients and controls. However, the mean values of volar tilts measured in standard lateral radiographs and in ATL radiographs were similar in patients and not significantly different in healthy controls. Conclusions: Volar tilt measurements obtained using anatomic tilt lateral radiographs provided moderate to excellent reliability. However, we found no statistically significant difference between volar tilts determined using ATL and standard lateral radiographs. Accordingly, standard lateral and ATL radiographs are interchangeable with respect to volar tilt measurements.

A state polytope decomposition formula

DoctorWe give a decomposition formula for computing the state polytope of a reducible variety in terms of the state polytopes of its components: If a polarized projective variety X is a chain of subvarieties X_i satisfying some further conditions, then the state polytope of X is the Minkowski sum of the state polytopes of X_i translated by a vector τ which can be readily computed from the ideal of Xi. The decomposition is in the strongest sense in that the vertices of the state polytope of X are precisely the sum of vertices of the state polytopes of X_i translated by τ. We also give a similar decomposition formula for the Hilbert-Mumford index of the Hilbert points of X. We give a few examples of the state polytope and the Hilbert-Mumford index computation of reducible curves which are interesting in the context of the log minimal model program for the moduli space of stable curves

Idiopathic extension contracture of the little metacarpophalangeal joint

We describe 4 patients with an extension contracture of the little metacarpophalangeal joint without definite cause. We encountered this entity only in adolescent girls. When treated conservatively, we observed no improvements in motion. The main pathology of this entity was a hypertrophied dorsal capsule. The 2 patients treated by surgical release of the fifth dorsal capsule and collateral ligaments achieved considerable flexion 2 years later. © 2013 American Society for Surgery of the Hand.

Two distinctive subungual pathologies: Subungual exostosis and subungual osteochondroma

Background: The purpose of this study was to present features that differentiate subungual exostosis from subungual osteochondroma. Methods: We treated 11 patients for subungual masses. All were confirmed by radiographic and histologic evaluations to be subungual exostosis or subungual osteochondroma. The study patients comprised eight female and three male patients with a mean age at presentation of 18.7 years (range 1.5 to 70.9). In the five patients with subungual exostosis, three (60%) had a toe lesion, and two (40%) had a finger lesion. In the six patients with subungual osteochondroma, four (67%) had a toe lesion, and two (33%) had inger lesions. We analyzed the clinical features, including trauma history, the existence of infection before surgery, tumor recurrence, and postoperative nail deformity. Results: In all patients, the lesions presented as an exophytic tumor of the nail apparatus, beneath the nail plate, which varied in size from 0.6 x 0.4 cm to 1.2 x 0.9 cm. Excision of these masses produced useful toes or fingers without pain, a tender scar, or nail deformity. Although nails were deformed preoperatively, they grew back without ridges or cracks within 3 to 5 months postoperatively. There were no recurrences based on clinical and radiographic evaluations, and both tumor types showed characteristic radiographic and histologic differences. Conclusions: Subungual exostosis and subungual osteochondroma are benign but have distinct osseous pathologies. We concluded that subungual exostosis is clinically, developmentally, radiographically, and histologically distinct from subungual osteochondroma.
