RESUMEN

AIM: The aim of this study was to evaluate hand function in children with Erb upper brachial plexus palsy. METHOD: Hand function was evaluated in 25 children (eight males; 17 females) with a diagnosed upper (C5/C6) brachial plexus birth injury. Of these children, 22 had undergone primary nerve reconstruction and 13 of the 25 had undergone simultaneous and/or secondary shoulder procedures. Hand function was evaluated using the nine-hole peg test at a mean age of 9 years (SD 2y 2mo), and compared with the contralateral, uninvolved hand. Results were compared with age- and sex-matched population norms, and correlated with shoulder outcomes using the Gilbert and Miami scores. RESULTS: Although shoulder function was graded as good or excellent in 24 of 25 children, hand function as measured by the nine-hole peg test was significantly altered in the involved hand in 80% (p=0.008). On average the participants took 18.8% longer to complete the task with the involved hand; this was significantly different from the expected difference of 7.2% (p=0.008). INTERPRETATION: Hand function is impaired in individuals with upper brachial plexus birth injury. These results suggest that from the initiation of treatment in this population, attention should be paid to recognizing and focusing therapy on subtle limitations of hand function.

RESUMEN

Research on attitudes regarding the use and timing of deep brain stimulation (DBS) has been mostly qualitative to this date. In this study, we aim to examine attitudes and perceptions about the use and timing of DBS in patients with Parkinson's disease (PD) who have not had DBS. We designed an online survey comprising Likert-type, multiple choice, and rank-order questions and distributed it to PD patients. We recruited participants via flyers, the Michael J. Fox Foundation Trial Finder, and the Parkinson Alliance website. We analyzed considerations for choosing or rejecting DBS and when participants would consider such a decision to be premature. Data were analyzed using descriptive and inferential statistics, including a multinomial logistic regression model. Among the 285 participants who reported not having undergone DBS, the most frequent concerns were related to the efficacy of DBS and not having exhausted medication alternatives. DBS was viewed as less convenient, effective, and safe when PD symptoms were still manageable by medication. Our regression model suggests that having fewer concerns over technical problems was a positive predictor of preferring early DBS, while concerns over DBS interfering with friendships and relationships was a negative predictor. Our results suggest that patients with PD who have not undergone DBS have a wide variety of attitudes regarding DBS and its timing. Given the increasing number of therapeutic options for PD, future work should compare perceptions and preferences regarding different PD treatment modalities to provide the best counseling for patients regarding their therapeutic options.

RESUMEN

Background: Various surgical techniques for treating avulsions of the flexor digitorum profundus tendon at the distal phalanx have been published but no ideal technique has emerged. We introduce a new all-internal 4-anchor flexor tendon repair technique and evaluate outcomes in three clinical cases. Methods: In this retrospective case series, we reviewed three patients that sustained an avulsion of the flexor digitorum profundus tendon at the distal phalanx. All patients were surgically treated with the four-anchor repair technique. Two titanium anchors were inserted into the distal phalanx and two all-suture anchors were inserted distal to the first set of anchors. The tendon was then attached to these four anchors using a Krackow stitch pattern and the anchors were sown to each other. Active flexion and extension of the proximal and distal interphalangeal joint were measured at 3-month, 12-month, and 5-year follow-up. Postoperative complications were documented. Results: All patients achieved excellent clinical outcomes according to assessment criteria. At 3-month follow-up, all patients regained full flexion; two patients had full extension, while one patient was 3 degrees short of full extension. At 12-month follow-up, all patients had full flexion and extension. Five-year follow-up demonstrated the same results with no loss of function, sensation or grip strength. The repairs healed without rupture, and no complications were reported. Conclusion: The 4-anchor flexor tendon repair is a viable surgical technique for zone 1 flexor digitorum profundus tendon repair or reconstruction. Further studies are needed to replicate these promising results and biomechanically validate this technique.Level of Evidence: IV.

RESUMEN

The outcomes of 20 patients diagnosed with osteoarthritis or rheumatoid arthritis with body mass index less than 18.5 (considered underweight) who received total hip arthroplasty at a single institution were reviewed. Surgical complications in the first 30 days after surgery included 1 prolonged surgical site drainage and 3 posterior dislocations. Two patients experienced medical complications that included hematemesis, confusion, aspiration pneumonia, and death. Sixty-five percent of the patients received at least one blood transfusion. Harris hip scores improved from 35 to 81 (P < .05) at an average of 6.1 years (2-10.1 years) of follow-up. Total hip arthroplasty is effective in patients who are underweight; however, they appear to be at an increased risk of dislocation and blood transfusion.

RESUMEN

The gene for cartilage oligomeric matrix protein (COMP) encodes a noncollagenous matrix protein that is expressed predominantly in cartilage. COMP gene expression is deficient in the Sox9-null mouse, but the molecular mechanism remains unknown. We have previously delineated a 30-bp negative regulatory element (NRE) and a 51-bp positive regulatory element (PRE) in the regulatory region of the COMP gene. Subsequently we isolated LRF transcription repressor as an NRE-binding protein and established that LRF inhibits COMP gene expression via recruiting histone deacetylase 1 (HDAC1) to the COMP promoter. In this study we demonstrated that Sox9, an essential transcription factor of chondrogenesis, binds to the COMP promoter at the PRE in which 13 nucleotides (TGTTTACCTTGTG) are required for the binding of Sox9. Sox9 activates COMP gene expression and this activation is PRE-dependent. Sox9 is required for COMP gene expression during chondrogenesis, since repression of Sox9 expression using the small interfering RNA approach inhibited COMP gene expression. In addition, activation of COMP gene expression by Sox9 requires the participation of transcription factors Sox5 and Sox6 as well as the coactivators CBP and p300 histone acetylase. It appears that there exists a balance between LRF repressor and Sox9 activator in the control of COMP gene, since transactivation of COMP gene by Sox9 was abolished by the coexpression of LRF, and excess Sox9 overcame the LRF-mediated inhibition. This study provides the first evidence that Sox9 directly associates with COMP gene promoter and that mediation of COMP gene activation by Sox9 involves Sox5, Sox6, CBP, and p300 coactivators.

RESUMEN

IFI16 is a member of the interferon-inducible p200-protein family, capable of modulating cell proliferation, and cellular senescence. In this study, these effects of IFI16 were studied in tumor cells derived from bone and cartilage. The level of IFI16 was markedly lower in human osteosarcomas as compared with its level in normal bone. Overexpression of functional IFI16 in human osteosarcoma and chondrosarcoma cell lines markedly inhibited colony formation, and significantly inhibited cell growth, an effect that could be reversed by introduction of gene specific siRNA into tumor cells. These inhibitory effects of IFI16 were associated with upregulation of p21 and inhibition of cyclin E, cyclin D1, c-Myc and Ras. In addition, ectopic expression of IFI16 in tumor cells increased senescence-associated beta-galactosidase and induced a senescence-like phenotype. In view of such effects, IFI16 might be a suitable target for therapeutic intervention in osteosarcoma and chondrosarcoma.

RESUMEN

OBJECTIVE: To compare the fixation stability of intramedullary nails to that of locked plates for the treatment of distal metaphyseal tibia and fibula fractures. METHODS: A simulated, distal metaphyseal tibia fracture was created in 8 pairs of cadaveric tibia-fibula specimens. One of each pair was treated using an intramedullary nail (Trigen IM Nail System; SN Richards, Memphis, TN) and the other with a locked plate (Peri-Loc Periarticular Locked Plating System; SN Richards). Each specimen was vertically loaded to 250 N in central, anterior, posterior, medial, and lateral locations; loaded to 250 N in cantilever bending in anterior to posterior and posterior to anterior directions; and loaded to 250 N mm in torsion. Load-displacement curves were generated to determine the construct stiffness for each loading scenario, with comparisons made between the 2 treatment groups. Each specimen was then cyclically loaded with 750 N vertical loads applied for 10, 100, 1000, and 10,000 cycles. Measurements of fracture displacements were made and compared between treatment groups. A fibular osteotomy was then created in each specimen at the same level as the tibia fracture to simulate a same-level tibia-fibular fracture. Torsional stiffness assessment and cyclic vertical loading for 10, 100, 1000, and 10,000 cycles were repeated and fracture displacement measurements were again obtained. RESULTS: The locked plate construct was stiffer than the intramedullary nail construct for central, anterior, and posterior loading scenarios (P < 0.005, P < 0.03, and P < 0.02, respectively). The intramedullary nail construct was stiffer than the locked plate construct for both anterior to posterior and posterior to anterior cantilever bending (P < 0.03 and P < 0.02, respectively). No statistically significant difference in stiffness was noted between treatment groups for medial and lateral vertical loading or for torsional loading (P = 0.09, P = 0.32, and P = 0.84, respectively). There was no significant difference between treatment groups with respect to fracture displacement after cyclic vertical loading. After creation of the fibular osteotomy fracture, construct displacements after 1000 and 10,000 cycles significantly increased and torsional stiffness significantly decreased for both treatment groups. The locked plate constructs had significantly less displacement after cyclic loading of 1000 and 10,000 than the locked nail constructs (P < 0.001 and P < 0.0001, respectively). Locked plate constructs were stiffer in torsion after osteotomy than the intramedullary nail constructs (P < 0.05). CONCLUSION: This study demonstrated that, in the treatment of distal metaphyseal tibia fractures, locked plates provided more stable fixation than intramedullary nails in vertical loading but were less effective in cantilever bending. An intact fibula in the presence of a distal tibia fracture improved the fracture fixation stability for both treatment methods. In fracture patterns in which the fibula cannot be effectively stabilized, locked plates offer improved mechanical stability when compared with locked intramedullary nails.

RESUMEN

The purpose of this report is to discuss the association of brachial plexus palsy and congenital deformations. We reviewed all charts of patients less than 1 year of age with obstetrical brachial plexus palsy evaluated by one of the authors (IA) between January 1998 and October 2005 at Miami Children's Hospital Brachial Plexus Center. Of 158 patients with obstetrical brachial plexus palsy, 7 had deformations (4.4%). Deformations were present in 32% of patients delivered by cesarean section, but in only 2% of patients delivered vaginally. The deformations were ipsilateral, involving the chest in two patients, distal arms in two patients, proximal arm in one patient, ear in one patient, and the leg in one patient. All patients with deformations had unilateral Erb's palsies. None had a history of maternal uterine malformation. Two presumptive mechanisms of injury, one causing the deformation (compressive forces) and one causing brachial plexus palsy at the time of delivery (traction forces), were present in all cases. The higher incidence of deformation in patients with obstetrical brachial plexus palsy born by cesarean sections and the presence of two presumptive mechanisms in all of the cases presented here raises the possibility that fetal deformations are a risk factor for obstetrical brachial plexus palsy.

RESUMEN

Postoperative medical complications after total hip arthroplasty (THA) and total knee arthroplasty (TKA) may occur in patients of any age. However, percentage of adverse events increases with increasing patient age and can cause significant morbidity and even mortality. It is important that the orthopedist identify risk factors and symptoms and be knowledgeable in the treatment of nonsurgical postoperative complications. Nonsurgical complications after THA and TKA include pulmonary embolism, fat embolism syndrome, pneumonia, myocardial infarction, postoperative delirium, cerebrovascular accident, urinary retention, urinary tract infections, and deep vein thrombosis.

RESUMEN

Ipsilateral femoral neck and femoral shaft fractures are rarely reported in the literature and represent a diagnostic and treatment challenge. Due to the possibility of missing a nonunion at either site, we recommend a high clinical suspicion and careful radiographic examination of both fracture sites. Because the development of nonunion at both sites is exceedingly rare, we report three cases of concomitant ipsilateral femoral neck and shaft nonunions that were treated by the senior author (KAE). Two patients were treated with a Pauwels osteotomy and a blade plate for the femoral neck nonunion and a reamed retrograde intramedullary nail for the shaft. One patient was treated with an antegrade reamed cephalomedullary intramedullary nail. All three patients' fractures united at a mean of 4.6 months and they are currently pain free and without physical limitations.

RESUMEN

The causes of brachial plexus palsy in neonates should be classified according to their most salient associated feature. The causes of brachial plexus palsy are obstetrical brachial plexus palsy, familial congenital brachial plexus palsy, maternal uterine malformation, congenital varicella syndrome, osteomyelitis involving the proximal head of the humerus or cervical vertebral bodies, exostosis of the first rib, tumors and hemangioma in the region of the brachial plexus, and intrauterine maladaptation. Kaiser Wilhelm syndrome, neonatal brachial plexus palsy due to placental insufficiency, is probably not a cause of brachial plexus palsy. Obstetrical brachial plexus palsy, the most common alleged cause of neonatal brachial plexus palsy, occurs when the forces generated during labor stretch the brachial plexus beyond its resistance. The probability of obstetrical brachial plexus palsy is directly proportional to the magnitude, acceleration, and cosine of the angle formed by the direction of the vector of the stretching force and the axis of the most vulnerable brachial plexus bundle, and inversely proportional to the resistance of the must vulnerable brachial plexus bundle and of the shoulder girdle muscles, joints, and bones. Since in most nonsurgical cases neither the contribution of each of these factors to the production of the obstetrical brachial plexus palsy nor the proportion of traction and propulsion contributing to the stretch force is known, we concur with prior reports that the term of obstetrical brachial plexus palsy should be substituted by the more inclusive term of birth-related brachial plexus palsy.

RESUMEN

Psoriatic arthritis is a complex, chronic inflammatory disease with both skin and joint involvement. Clinical presentation varies considerably among patients and during the course of the disease. Assessment of patients for psoriatic arthritis requires careful attention to patient history, a focused physical examination, and inspection for characteristic radiographic changes. Although this disease was once thought to be a rare and mild form of arthritis, recent studies have shown that patients with psoriatic arthritis may develop significant disability, with up to 20% of cases demonstrating a rapidly progressive, debilitating clinical course. Orthopedic manifestations of the disease can be severe and can cause significant physical disability. Although surgical intervention for psoriatic arthritis is relatively uncommon, having an understanding of the assessment, available treatment options, and surgical considerations allows for improved outcome in the management of this complex patient population.

RESUMEN

The authors report a 7-day-old girl born with a hemangioma involving the right side of the scalp and neck who developed ipsilateral brachial plexus palsy at 5 days of age. Imaging studies confirmed the presence of a cavernous hemangioma in the vicinity of the brachial plexus. She was treated with intravenous corticosteroids and her palsy resolved in 5 days. Only 1 prior case of hemangioma producing brachial plexus palsy has been reported; this patient was not treated with corticosteroids and had a partial recovery. The authors believe that the quick recovery after initiating systemic steroids was due to relief of nerve compression (neuropraxia) resulting from shrinkage of the cavernous hemangioma. The purpose of this article is to describe an uncommon cause of neonatal brachial plexus palsy and to report the effectiveness of early intravenous corticosteroid treatment in a patient with brachial plexus palsy due to a cavernous hemangioma.

RESUMEN

We report 2 patients with obstetrical brachial plexus palsy, ipsilateral leg weakness, and contralateral motor cortical dysplasia. To our knowledge, this is the first description of such an association. In both cases, the diagnosis of obstetrical brachial plexus palsy was established clinically shortly after birth and later confirmed neurophysiologically. Motor cortex dysplasia was diagnosed by magnetic resonance imaging (MRI). The association of obstetrical brachial plexus palsy and contralateral motor cortex dysplasia, a condition known to produce congenital hemiparesis, raises the possibility that the cortical dysplasia was a predisposing factor for obstetrical brachial plexus palsy in these cases.

RESUMEN

Among 25 patients of mean age 91.5 years (range, 90-96 years) who received a total hip or knee arthroplasty at the authors' institution, 8% experienced surgical complications, 56% experienced at least 1 medical complication, and 80% received perioperative blood transfusions. At a mean follow-up of 4.1 years, patients were experiencing pain reduction and somewhat higher functional capacity and had slightly better survival characteristics than age-matched controls. Total hip and knee arthroplasty patients in this cohort should be told that they have a higher likelihood of experiencing perioperative medical complications and of receiving a blood transfusion than younger individuals; at the same time, they can expect pain relief as well as equal or better survival than their age-matched peers.

RESUMEN

Over a 5-year-period, 26 infants underwent a partial transfer of the spinal accessory nerve into the suprascapular nerve using a nerve graft, as part of the repair of a brachial plexus birth injury. At a minimum follow-up of 2.5 years, all children had shoulder function of Grade 4 or better using a modified Gilbert Scale. Average lateral rotation was measured at 53 degrees.
