Distal Chevron Osteotomy vs The Simple, Effective, Rapid, Inexpensive Technique (SERI) for Mild to Moderate Isolated Hallux Valgus: A Randomized Controlled Study.

BACKGROUND: Hallux valgus is a common foot deformity that leads to functional disability with serious sequelae. Minimally invasive surgery is often used to treat hallux valgus in order to reduce wound complications and improve recovery time. The objective of this study was to compare a Simple, Effective, Rapid, Inexpensive (SERI) technique with a simple Chevron technique in patients with minimum of 1-year follow-up. METHODS AND MATERIALS: Between the years 2014-2015, we performed a prospective study comparing the SERI minimally invasive technique to treat symptomatic hallux valgus with a standard chevron osteotomy technique. All procedures were performed by a single fellowship trained foot and ankle surgeon. Twenty-one patients were randomized to the SERI cohort and 15 to the standard Chevron technique. RESULTS: The mean preoperative intermetatarsal angle (IMA) of the SERI group was 14.8 ± 1.9 (11.9-22.9). The mean preoperative IMA of the Chevron control group was 13.3 ± 2.3 (10.4-18.2) (p = 0.038). The mean IMA two weeks after the surgery was 6.0 ± 2.3 (2.4-12) in the SERI group, and 6.1 ± 3 (2.6-13.1) in the control group. At the two-week and 1-year follow-up, there was no significant difference found in the IMA between the two groups (p = 0.871). The mean hallux valgus angle reduction was 11.85 ± 4.88 (3-20.8) and 11.09 ± 6.51 (- 1.1 to 22.5) in the SERI and Chevron groups, respectively (p = 0.69). Neither groups reported symptomatic transfer metatarsalgia throughout the follow-up period. The SERI group had increased metatarsophalangeal joint (MTPJ) motion (p < 0.001); however, all other parameters with similar. CONCLUSION: The SERI technique provided comparable outcomes at up to 1-year follow-up when compared with a standard Chevron osteotomy for moderate hallux valgus. This study demonstrated good reproducible results using the SERI technique for moderate hallux valgus. LEVEL OF EVIDENCE: Level II Prospective Study. TRIAL REGISTRATION: Approved by local IRB at MMC.

The effect of army vest design on the occurrence of stress fractures and overuse injuries in female military recruits.

INTRODUCTION: Stress fractures (SFs) occur when microdamage caused by repetitive mechanical load exceeds the biological load-bearing capacity of the bone. The study objective was to test whether a vest specifically designed and manufactured for female recruits, compared with the standard vest used on a regular basis by Border Police recruits, would reduce the incidence of SF in female Border Police recruits. Data based on reports of military personnel show that women are more likely to sustain SFs. METHODS: A follow-up of 240 female Border Police infantry recruits, divided into two trial groups, was conducted from 2007 to 2009. Two different vests were evaluated-the standard special unit fighting vest, which was conventionally used by both men and women during basic training, and the new fighting vest, specially design for female body shape. RESULTS: No significant difference was noted in the number of SFs between the two groups which may be attributed to increased weight of the new vest. There was a lower incidence of long bone SFs which may have been due to the superior vest design. The female Border Police Infantry recruits expressed great satisfaction with the new vest. CONCLUSIONS: Increased effort should be invested to further reduce the weight of female combat gear, alongside efforts to improve fit and comfort.

Symptomatic pulmonary embolism after outpatient arthroscopic procedures of the knee: the incidence and risk factors in 418,323 arthroscopies.

Pulmonary embolism is a serious complication after arthroscopy of the knee, about which there is limited information. We have identified the incidence and risk factors for symptomatic pulmonary embolism after arthroscopic procedures on outpatients. The New York State Department of Health Statewide Planning and Research Cooperative System database was used to review arthroscopic procedures of the knee performed on outpatients between 1997 and 2006, and identify those admitted within 90 days of surgery with an associated diagnosis of pulmonary embolism. Potential risk factors included age, gender, complexity of surgery, operating time defined as the total time that the patient was actually in the operating room, history of cancer, comorbidities, and the type of anaesthesia. We identified 374,033 patients who underwent 418,323 outpatient arthroscopies of the knee. There were 117 events of pulmonary embolism (2.8 cases for every 10 000 arthroscopies). Logistic regression analysis showed that age and operating time had significant dose-response increases in risk (p < 0.001) for a subsequent admission with a pulmonary embolism. Female gender was associated with a 1.5-fold increase in risk (p = 0.03), and a history of cancer with a threefold increase (p = 0.05). These risk factors can be used when obtaining informed consent before surgery, to elevate the level of clinical suspicion of pulmonary embolism in patients at risk, and to establish a rationale for prospective studies to test the clinical benefit of thromboprophylaxis in high-risk patients.

Prevention of avascular necrosis in displaced talar neck fractures by hyperbaric oxygenation therapy: a dual case report.

Talar neck fractures are a rare injury that account for less then 2% of all foot fractures. Displaced fractures are associated with an exceedingly high rate of avascular necrosis (AVN). The incidence of AVN following Hawkins Type 3 fractures of the talar neck may approach 100%, particularly if diagnosis and reduction are delayed. Severe cases may present as pain and disability of the ankle and the subtalar joints due to a talar dome collapse, resulting in degenerative changes that usually require hind foot arthrodesis. We present two cases of traumatic displaced talar neck fractures which were treated surgically more than 2 weeks following injury due to a delay in diagnosis. Both patients underwent hyperbaric oxygen therapy (HBOT) after the operation and neither resulted in AVN of the talus in a three-year follow-up. We suggest that this favorable result may be due to the beneficial effects of HBOT.

Bilateral femoral neck fractures in long-term steroid use for systemic lupus erythematosus and chronic lung disease.

Bilateral femoral neck fractures present a rare injury. Only one report to our knowledge was not related to an acute severe traumatic event, and developed years after pelvic irradiation. Chronic steroid use may severely decrease bone strength, thus increasing the risk for such an injury. Patients with chronic lung disease and chronic inflammatory conditions are frequently treated with steroids such as prednisone at doses that may exceed 2.5 mg a day for long durations. Fractures at vulnerable sites such as the femoral neck may then follow without any severe trauma. Awareness of the detrimental effect of chronic steroid consumption on bone morphology, and familiarity with treatment alternatives to improve bone mass is important to prevent such a severe injury. We describe two cases of bilateral femoral neck fractures in women who were treated for years with orally administered prednisone. The rarity of such an injury of bilateral hip fractures and the fact that neither of the patients sustained major trauma, strongly suggests that both cases were related to impaired bone metabolism due to the effect of prolonged steroid consumption. The biological effects of different roots of steroid administration on bone turnover, as well as several strategies that can be implemented by clinicians to treat and prevent steroid induced osteoporosis and fractures, are further clarified in this article.

A prospective biomechanical study of the association between foot pronation and the incidence of anterior knee pain among military recruits.

Excessive foot pronation has been considered to be related to anterior knee pain. We undertook a prospective study to test the hypothesis that exertional anterior knee pain is related to the static and dynamic parameters of foot pronation. Two weeks before beginning basic training lasting for 14 weeks, 473 infantry recruits were enrolled into the study and underwent two-dimensional measurement of their subtalar joint displacement angle during walking on a treadmill. Of the 405 soldiers who finished the training 61 (15%) developed exertional anterior knee pain. No consistent association was found between the incidence of anterior knee pain and any of the parameters of foot pronation. While a statistically significant association was found between anterior knee pain and pronation velocity (left foot, p = 0.05; right foot, p = 0.007), the relationship was contradictory for the right and left foot. Our study does not support the hypothesis that anterior knee pain is related to excessive foot pronation.

Comparison between nafarelin acetate and D-Trp6-LHRH for temporary pituitary suppression in in vitro fertilization (IVF) patients: a prospective crossover study.

PURPOSE: Nafarelin acetate is a new gonadotropin releasing (GnRH) agonist analogue with unique potency, intranasal administration, and convenient storage. Hence, nafarelin was considered as an alternative for temporary pituitary suppression in patients undergoing ovulation induction in IVF. A crossover treatment in a prospective study was performed including 40 women with bilateral obstructed tubes and normal ovarian function, treated in 80 ovulation induction cycles using the long protocol. Twenty patients used nafarelin acetate 600 micrograms/daily in their first cycle and received D-Trp6-LHRH, 0.5 mg/daily, in their following cycle. The other 20 women used decapeptyl in their cycle and received nafarelin in the second. RESULTS: Estradiol suppression was achieved by both D-Trp6-LHRH and nafarelin at equal time intervals. The average total number of ampoules (P = 0.0005) and the length of administration of hMG required for ovarian stimulation (P = 0.0002) and the time interval between GnRHa initiation to oocyte retrieval (P = 0.04) was significantly lower in nafarelin cycles. The number and the distribution between large and small follicles as well as the average number of oocytes retrieved did not differ between the two GnRH analogues. CONCLUSION: Our results demonstrate that nafarelin acetate is comparable to D-Trp6-LHRH for temporary pituitary suppression used for controlled ovarian stimulation in IVF patients. However, using nafarelin ovarian stimulation was achieved with few ampoules of hMG, administered for a shorter period of time, thus with a lesser cost.
