Published: July 2013

ABSTRACT

Introduction
Distal biceps tendon ruptures are a rare injury and surgical reconstruction is typically recommended for chronic ruptures. There is no consensus regarding the most appropriate reconstruction technique. We present our experience with fascia lata autograft reconstructions of chronic distal biceps tendon ruptures using a modified single incision technique and distal fixation with suture anchors.

Materials and methods
We retrospectively reviewed the outcome of 12 male patients with chronic distal biceps tendon ruptures who had reconstruction using a fascia lata autograft through a single anterior approach. The age ranged from 29 to 62 years. The average delay to surgery was 26.5 weeks (range 6-68 weeks). A modified single anterior incision was utilized for all patients. Fascia lata autograft was attached distally to the bicipital tuberosity using suture anchors. Tension was set with the elbow in 50° of flexion. The average follow-up was 14.5 months (range 1.5-66 months). All patients were treated by the senior author (MSM).

Results
Eleven patients (92%) reported subjective improvement in elbow flexion and supination strength, as well as painless range of motion. The average elbow flexion/ extension arc was 126° (5° flexion to 131° flexion) and the average supination/pronation arc was 167 degrees (87° pronation to 80° supination). Five patients underwent isokinetic flexion strength testing which revealed a restoration of 86% of strength when compared to the uninvolved side. Four patients underwent supination isokinetic strength testing which revealed a restoration of 87% of strength when compared to uninvolved side. Four patients reported numbness in the superficial radial nerve distribution that recovered within 12 months. There were no cases of heterotopic ossification or graft rupture. There was one case of wound dehiscence at the elbow that required local flap coverage and went on to heal uneventfully. Aside from a small muscle bulge at the donor site, there were no donor site complications.

Conclusion
To our knowledge, this is the largest case series of patients undergoing distal biceps tendon reconstruction using fascia lata autograft. Our study has demonstrated a low complication rate with functional results similar to those reported in the literature utilizing a similar technique. We conclude that this technique offers a surgical treatment alternative that yields satisfactory functional outcomes with a low risk of complication.

ABSTRACTPurposeOsteochondroplasty of the femoral head-neck junction can improve hip pain and function in patients with femoroacetabular impingement. We report our initial series of patients undergoing surgical treatment for symptomatic CAM type femoroacetabular impingement using a combined arthroscopic and mini-open approach.Materials and methodsA retrospective chart review of 20 consecutive patients was performed. Seventeen patients had adequate follow-up for inclusion. Preoperative clinical and radiographic characteristics as well as intraoperative findings were obtained from patient records. Postoperative Harris Hip scores and VAS pain scores were recorded at final follow-up.ResultsAt an average of 27.8 months (range 12-48 months), the mean Harris Hip score improved from 64.7 preoperatively to 86.8 (p < 0.001). The mean VAS pain score improved from 4.80 to 1.53 (p = 0.001). Two patients (11.7%) underwent total hip arthroplasty at an average of 15 months postoperatively. Fourteen patients (82%) stated they would have the procedure again. There were no significant complications.ConclusionSurgical treatment of CAM type femoroacetabular impingement using a combined arthroscopic and mini-open anterior hip approach has a low complication rate and improves functional and pain scores at short-term follow-up.Watters TS, Kaufman AM, Solic JM, Stinnett SS, Olson SA.

ABSTRACT
Stress fractures of the foot and ankle are a common problem encountered by athletes of all levels and ages. This review summarizes the history and physical exam findings, radiographic imaging, diagnosis and treatment of stress fractures of the foot and ankle in those participating in athletic activities.
These injuries can be divided into low- and high-risk based upon their propensity to heal without complication. A wide variety of nonoperative strategies are employed based on the duration of symptoms, type of fracture, and patient factors such as activity type, desire to return to sport and compliance. Operative management has proven superior in several high risk types of stress fractures. Evidence on pharmacotherapy and physiologic therapy such as bone stimulators is evolving.
A high index of suspicion for stress fractures is appropriate in many high-risk groups of athletes with lower extremity pain. Proper and timely workup and treatment is successful in returning these athletes to sport in many cases. Education of athletes as well as their families, training and coaching staff is important. Attention to training regimens, technique, equipment and proper nutrition is paramount in the prevention of these injuries.

Published: July 2013

ABSTRACTIntroductionThe objective of this investigation was to evaluate the effects of delayed surgery on infection rates of open tibia fractures in a rabbit model. Our hypothesis was that delaying irrigation and debridement (I&D) would increase the risk of bony and soft tissue infection when antibiotics were withheld.Materials and methodsA drill hole was created in the rabbit tibia and inoculated withStaphylococcus aureus. Animals underwent I&D at controlled delayed times of 6 hours (n = 11), 12 hours (n = 9) and 24 hours (n = 10). A stainless steel pin was inserted to mimic definitive fracture fixation with a metal prosthesis. No antibiotics were administered. Animals were sacrificed at 4 weeks and evaluated for infection.ResultsThe percent of soft tissue infections with I&D delays of 6, 12 and 24 hours were 18, 22 and 40%, respectively [p = 0.59; odds ratio (OR) = 3]. The percentage of animals with osteomyelitis with I&D delays of 6, 12 and 24 hours were 9, 22 and 50%, respectively (p = 0.12; OR = 10).DiscussionIn the current model, delaying I&D from 6 to 24 hours may increase the rate of postoperative osteomyelitis and further investigation is warranted.Kokko KP, Kang QK, Wen X, An YH, Barfield WR, Hartsock LA.

Published: July 2013

ABSTRACT

Introduction
Unicompartmental knee arthroplasty (UKA) is a treatment option in patients with unicompartmental degenerative disease. Compared to total knee arthroplasty (TKA), the advantages of UKA include accelerated recovery and cruciate ligament retention. These advantages, along with emerging evidence that mild patellofemoral joint osteoarthritis does not compromise results of UKA have encouraged expansion of the indications for UKA. Symptomatic lateral patellofemoral joint degenerative disease is a common cause of UKA revision. Partial lateral patellar facetectomy can provide relief from symptoms of lateral patellofemoral degenerative disease. We hypothesize that simultaneous UKA and lateral patellar facetectomy provides durable pain relief and functional improvement in a patient population with degenerative disease of one tibiofemoral compartment and the lateral patellofemoral joint.
Materials and methods: Between 2004 and 2008, 11 lateral UKA's were performed in association with partial lateral patellar facetectomy in 11 female patients (mean age: 66.7 years) with degenerative changes in one tibiofemoral compartment and the lateral patellofemoral joint. Patients were followed clinically and radiographically for a mean of 5 years.

Results
No patient underwent revision surgery in the followup period. The mean international Knee Society (IKS) knee score improved from 64.9 ± 11.2 points preoperatively to 87.5 ± 12.6 points at final follow-up (p = 0.01). The mean IKS functional score improved from 65.9 ± 23.5 points preoperatively to 83.2 ± 23.3 points at final follow-up (p = 0.012). The mean Kujala score was 84.3 ± 13.5 points postoperatively. Progression of patellofemoral OA was observed in one patient.

Conclusion
Simultaneous UKA and partial lateral patellar facetectomy is a viable treatment option for symptomatic degenerative disease involving one tibiofemoral compartment and the lateral patellofemoral joint. This treatment approach may be a useful alternative to TKA or bicompartmental arthroplasty in a carefully selected patient population.

ABSTRACT

Objectives
To evaluate the clinical and radiographic outcomes of patients undergoing interposition reconstruction of massive, otherwise irreparable rotator cuff tears through a mini-open approach with the use of a porcine dermal tissue matrix.

Materials and methods
We performed a prospective observational study of 26 patients (27 shoulders) who underwent reconstruction of massive rotator cuff tears using dermal tissue matrix xenograft. Pain level (scale 0-10, 10 = severe pain), active range of motion, and supraspinatus and external rotation strength were assessed. Additional outcome measures included modified American shoulder and elbow score (MASES) and short form-12 (SF-12) score. Clinical and radiographic analyses were performed at an average 32 months follow-up period (minimum 2-year follow-up). Ultrasound imaging (static and dynamic) of the operative shoulder was performed at final followup to assess the integrity of the reconstruction.

Results
Mean patient age was 60. Mean pain level decreased from 5.1 to 0.4 (p = 0.002). Mean active forward flexion, abduction, and external rotation motion improved from 138.8 to 167.3 (p = 0.024), 117.9 to 149.3 (p = 0.001) and 57.7 to 64.7° (p = 0.31), respectively. Supraspinatus and external rotation strength improved from 7.2 to 9.4 (p = 0.001) and 7.4 to 9.5 (p = 0.001), respectively. Mean MASES improved from 62.7 to 91.8 (p = 0.0007) and mean SF-12 scores improved from 48.4 to 56.6 (p = 0.044). Twenty-one patients (twenty-two shoulders) returned for a dynamic and static ultrasound of the operative shoulder at a minimum 2-year follow-up. Sixteen (73%) demonstrated a fully intact tendon/graft reconstruction. Five (22%) patients had partially intact reconstructions, and one (5%) had a complete tear at the graft-bone interface due to suture anchor pullout as a result of a fall. There were no cases of infection or tissue rejection.

Conclusion
We present a reproducible surgical technique for the management of massive irreparable rotator cuff tears. In our series, patients demonstrated a significant improvement in both subjective and objective clinical outcomes. Radiographic analysis demonstrated that the majority of patients had a fully intact reconstruction at a minimum 2-year follow-up.

ABSTRACT
There are many orthopaedic pioneers whose impact continues to live on today, teaching us valuable lessons, inspiring us to greatness, and touching the lives of generations of future patients. Professor Ilizarov, a nonsurgically trained general practitioner, represents such an important orthopaedic forefather for his instruction on how to grow bones and soft tissues that would otherwise face catastrophic deformity and dysfunction. A simple look at his life, his innovation, and astonishing legacy serves as an inspiration to all involved in the amazing field of orthopaedics.

Community and Ritual Within the Mississippian Center at Town Creek
Authors: Boudreaux Edmond A. 
Published: July 2013

AbstractThis article evaluates aspects of an occupational history that was developed for the Town Creek site, a small Mississippian center in the North Carolina Piedmont that was occupied sometime between A.D. 1150–1400. Town Creek’s occupational history suggests that its Mississippian community consisted of multiple, discrete household groups, and that these groups were important throughout the center’s existence. Analyses of architectural, mortuary, and ceramic data indicate that Town Creek began as a town with a substantial domestic population, but it evolved into more of a vacant center later in time. This decline in domestic population coincided with significant evidence for site-wide ritual activity that included the construetion of a platform mound and the use of cemeteries in former house locations. Parallels between the small center at Town Creek and some of the largest Mississippian centers, especially the persistence of household-group spaces and an emphasis on ritual activities later in time, suggest that interaction among discrete social groups within a ritual context was a salient part of being Mississippian.
A Contextual and Iconographic Reassessment of the Headdress on Burial 11 From Hopewell Mound 25
Authors: Giles Bretton T. 
Published: July 2013

AbstractI explore in this paper the significance of the headdress interred on Burial 11 under Hopewell Mound 25 by reexamining its archaeological context and the history of its interpretation. Following Shetrone’s (1926) initial interpretation, I argue that it was an avian headdress that specifically portrayed a two-headed raptor. I support this reassessment with an iconographie analysis of related representations from the Central Ohio River Valley, especially the imagery engraved on a femur from Hopewell Mound 25. I also delve into what these two-headed raptors might have meant to people in the Eastern Woodlands.
Accelerator Mass Spectrometry14C Dating and the Antiquity of Shell-Tempered Ceramics from the Chesapeake Bay and Middle Atlantic
Authors: Rick Torben C. , Lowery Darrin L. 
Published: July 2013

AbstractCeramics typologies have long been used to build artifact, site, and regional chronologies. Direct accelerator mass spectrometry (AMS)14C dating of shell-tempered ceramics offers a promising tool for updating and improving these chronologies. Few studies have14C dated shell fragments from shell-tempered pottery, however, and questions remain about potential biases from “old shell,” the reservoir effect, and other variables. Forty-five direct AMS14C assays on shell-tempered pottery and associated shell, charcoal, and bone from nine archaeological sites in Virginia and Maryland provide a framework to test this method. AMS14C assays from one site may have problems with old shell, but most of the calibrated direct and associated age estimates overlap. One of our samples is the oldest securely dated shell-tempered pottery in North America at ~1000 cal B.C. Our study demonstrates the promise of AMS14C dating shell-tempered pottery for refining ceramic and regional chronologies in coastal and other areas around the world.

AbstractCardiomyopathies are remarkably variable in form. Although hearts may be dilated or hypertrophic, the spectrum of cardiomyopathies includes left ventricular noncompaction/hypertrabeculation and right ventricular wall disorders. These conditions have been increasingly recognized in patients given advances in clinical diagnostics. Here we present information on cardiac pathophysiology, from ventricular wall formation and trabeculae in model organisms to pediatric and adult disease. Many genes to affect the ventricular phenotype, and this has implications for deciphering developmental and disease pathways and for applying testing for clinical care. © 2013 Wiley Periodicals, Inc.
Significance of grooming behavior in two polygynous groups of western black crested gibbons: Implications for understanding social relationships among immigrant and resident group members

Published: July 2013

AbstractIn primates, grooming is considered among the most common behaviors for maintaining social bonds; however, to date, few studies have examined grooming behavior in gibbon species in detail. We used both a 5‐min interval scan method and social network analysis to study grooming in two groups of polygynous western black‐crested gibbon (Nomascus concolor) in Wuliang Mountain, Central Yunnan, China. Individuals in both groups spent little time in social grooming (1.45% and 1.97% of active time). We compared the two groups' grooming networks and found that the group that maintained a more stable social unit had a more complex grooming network while the group with new immigrants had a grooming network characterized by fewer grooming pairs. Females in both groups played important roles in the grooming network. A newly immigrant female spent the most time grooming others and chose the resident adult female as her main adult grooming partner. Other females from both groups chose the adult male as their primary grooming partner (except their offspring). A sub‐adult male who had resided in his natal group for 2 years after maturing into an adult also groomed more and was at the center of the network. This male finally replaced the breeding male in his group 3 years after our data collection period ended. We hypothesize that the immigrant female and the resident young adult male engaged in more extensive grooming interactions as a behavioral strategy to gain tolerance from long‐term residents. Our results suggest that female gibbons in polygynous groups actively cooperate in maintaining social relationships rather than co‐exist through tolerance or avoidance. Our observations indicate that grooming networks in crested gibbons reflect individual dynamics and partly support the social cohesion hypothesis for primate grooming. In this regard, we suggest that changes in gibbon grooming networks can be used to predict social change. Am. J. Primatol. 75:1165–1173, 2013. © 2013 Wiley Periodicals, Inc.
The degradation and charring of flame retarded epoxy resin during the combustion

Published: July 2013

ABSTRACTTo study flame retardant mechanism of epoxy resin (EP) by octaphenyl silsesquioxane and 9,10‐dihydro‐9‐oxa‐10‐phosphaphenanthrene‐10‐oxide, an experimental method is set up to investigate the residue of the EPs, which is extinguished during the cone calorimeter testing at different times. The chemical structures of the residues are investigated by the FTIR and XPS. The breakdown of EPs network and formation of new crosslinking structure are supported by the FTIR analysis. The changes of C and O concentrations in the condensed phase during the combustion are investigated by XPS in detail. Moreover, formation of organic carbon is uncovered by the plasmon loss curves based on XPS that could track the carbon crosslinking. These results exhibited a whole degradation and charring process of EP during the combustion: degradation of EP chain, more crosslinking charring, and thermal oxidation of the char. Furthermore, a program of combustion and degradation process of EPs is described in this research. © 2013 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 130: 4119–4128, 2013
Effects of nano‐TiO2 on the properties and structures of starch/poly(ε‐caprolactone) composites

Published: July 2013

ABSTRACTPoor physical properties resulting from low interfacial interactions between hydrophilic biopolymers and hydrophobic thermoplastic matrices have been one of the biggest obstacles in preparing quality biomass materials. This study concentrates on the effects of nano‐TiO2 on the properties and structure of starch/poly (ε‐caprolactone) (PCL) composites. The molecular and crystal structures of the composites were characterized by using Fourier transform infrared spectroscopy, differential scanning calorimeter (DSC), X‐ray diffraction (XRD), and field emission scanning electron microscope. The results indicated that an interpenetrating network structure formed by adding nano‐TiO2 into starch/PCL composites. The DSC and XRD analysis indicated that the crystallinity degree and the crystallization rate of the composites reduced, whereas the crystal form and crystal size were unchanged. The results also showed that the mechanical properties and water resistance of the composites were improved significantly with the addition of nano‐TiO2, whereas their transparency decreased. © 2013 Wiley Periodicals, Inc.
