Simultaneous Pantalar Dislocation and Bimalleolar Ankle Fracture.

A 17-year-old boy presented with a totally dislocated talus and open bimalleolar ankle fracture dislocation. After thorough debridement and irrigation, the talus and bimalleolar fracture were reduced and fixed. At 21 months after surgery, he could walk using regular shoes without any aid but with moderate pain in the sinus tarsi during activities. No evidence of osteonecrosis or infection was seen in the last radiograph, except for a small degree of narrowing in the talonavicular joint. Reimplantation and fixation of pantalar dislocation seems to have an acceptable outcome.

Evaluation of the efficiency of various force configurations on scoliotic, lordotic and kyphotic curves in the subjects with scoliosis.

BACKGROUND: The efficiency of the braces designed for scoliotic subjects depends on configurations and also magnitudes of the forces used to stabilize and correct scoliotic curve. However, the effects of various force configurations on the spinal curves in sagittal plane should also be considered. The aim of this study was to determine the efficiency of various force configurations on scoliotic, lordotic and kyphotic curves. METHOD: A 3d model of spine was developed based on CT scan images of spine obtained from a scoliotic girl. The model was exported to Abaqus software to check the effects of various force configurations and magnitudes on spinal curves. The spinal curves in thoracic and lumbar, lordotic and kyphotic curves were evaluated in this study. Transverse forces, vertical forces and combination of transverse and vertical forces were selected in this study. RESULTS: The results of this study showed that use of transverse forces did not influence the scoliotic curve significantly. Vertical directed forces not only decreased scoliotic curves but also decreased lordotic and kyphotic curves. It seems that a combination of both transverse and vertical directed forces decreased scoliotic curves but did not influence spinal curves in sagittal plane. CONCLUSION: It is recommended to use a combination of transverse and vertical forces to decrease scoliotic curve without significant side effects on the spinal curves in sagittal plane. As this is a case study the outputs of the study should be used with caution.

An evaluation of the efficiency of endpoint control on the correction of scoliotic curve with brace. A case study.

PURPOSE: The use of braces is one of the conservative treatment approaches recommended for scoliotic subjects. However, the main question posted here is how to improve the efficiency of braces to control the scoliotic curve or to decrease its progression. The aim of this study was to evaluate the efficiency of various boundary conditions (endpoint control) of brace on the correction of scoliotic curves. METHOD: CT scan images of a scoliotic subject, with double lumbar and thoracic curves, was used to produce 3d model of spine. The correction of spine (decrease in scoliotic curves) was determined following the use of transverse (lateral-to-medial direction) and the combination of transverse and vertical (upward directed force, traction) forces on spine in Abaqus software. The effects of pelvic fixation (pelvic basket of a brace) on both sides (basket enclosed pelvic in both sides), on one side (basket enclosed the pelvic in only one side), and fixation of lumbar (part of the brace encircled the lumbar area) were evaluated in this study. RESULTS: The results of this study showed that the effect of vertical forces (traction) was more than that of transverse force. Moreover, the combination of vertical and transverse forces on lumbar and thoracic curves correction was more than that of other conditions (only transverse forces). The best correction was achieved with lumbar fixation and with combination of vertical and transverse forces. CONCLUSIONS: The use the combination of vertical and transverse forces may be suggested to correct the scoliotic curve. Moreover, the efficiency of lumbar fixation in frontal plane seems to be more than pelvic fixation to correct scoliotic curve. The outputs of this study can be used to design new braces for scoliotic subjects.

Clinical, Functional, and Radiologic Outcome of Single- and Double-Level Transforaminal Lumbar Interbody Fusion in Patients with Low-Grade Spondylolisthesis.

OBJECTIVE: The main objective is to determine the functional, clinical, and radiological outcome of patients with low-grade spondylolisthesis undergoing single- or double-level transforaminal lumbar interbody fusion (TLIF). MATERIALS AND METHODS: This quasi-interventional study was conducted during a 2-year period from 2016 to 2018 in Shiraz, Southern Iran. We included all the adult (≥18 years) patients with low-grade spondylolisthesis (Meyerding Grade I and II) who underwent single- or double-level TLIF in our center. The spinopelvic parameters including pelvic incidence (PI), pelvic tilt (PT), sacral slope (SS), lumbar lordosis (LL), and segmental LL (SLL) were measured. The pain intensity and disability were measured utilizing the visual analog scale (VAS) for back and leg pain and Oswestry Disability Index (ODI), respectively, after 1 year. RESULTS: Overall, we included a total number of 50 patients with mean age of 54.1 ± 10.48 years. After the surgery, the PI (P = 0.432), PT (P = 0.782), and SS (P = 0.466) were not found to be statistically changed from the baseline. However, we found that single- or double-level TLIF was associated with increased LL (P < 0.001) and SLL (P < 0.001). Regarding the clinical outcome measures, both back (P = 0.001) and leg (P < 0.001) VAS improved after the surgery significantly. In addition, we found that improved leg VAS was positively correlated with improved ODI (r = 0. 634; P < 0.001). CONCLUSION: Single- or double-level TLIF is associated with increased global and SLL along with improved leg and back pain and disability in patients with low-grade spondylolisthesis. Interestingly, improved leg pain is correlated to improved disability in these patients.

MORTALITY AND FUNCTION AFTER SURGICALLY-TREATED HIP FRACTURE IN ADULTS YOUNGER THAN AGE 60.

OBJECTIVE: Hip fractures in young adults can cause poor functional capacity throughout life because of several complications. The purpose of this study was to prospectively evaluate 1-year mortality and functional outcomes for patients aged 60 years or younger with hip fracture . METHODS: We prospectively obtained data for all consecutive patients aged 60 or younger with any type of hip fracture who were treated operatively between 2008 and 2014. After one year, patient outcomes were evaluated according to changes in pain severity, functional status (modified Barthel index), and mortality rate . RESULTS: Of the total of 201 patients, 132 (65.7%) were men (mean age: 41.8 years) and 69 (34.3%) were women (mean age: 50.2 years) (p<0.001). Reduced pain severity was reported in 91.5% of the patients. The mean modified Barthel index was 22.3 in men and 18.6 in women (p<0.001). At the one-year follow-up, 39 cases (19.4%) were dependent on walking aids while only 17 patients (8.5%) used walking aids preoperatively (p<0.001). Seven patients (4 men and 3 women) died during the one-year follow-up period; 2 died in the hospital after surgery . CONCLUSION: Hip fractures in young adults have a low mortality rate, reduction in pain severity, and acceptable functional outcomes one year after surgery. Level of Evidence II, Prospective Comparative Study.

Traumatic Retrolisthesis of L5 and L5/S1 Extruded Disc Herniation; A Case Report and Review of the Literature.

Traumatic retrolisthesis is a rare injury and may result in intervertebral disc extrusion and nerve root injury. These injuries are highly unstable and require surgery for decompression and stabilization. Traumatic retrolisthesis of L5 with acute L5/S1 disc extrusion associated with nerve root injury has not been reported previously in English literatures. We herein report a case of traumatic retrolisthesis of L5 and extruded disc. A 22 year-old patient presented with lower extremity weakness due to L5/S1 retrolisthesis and traumatic acute L5/S1 disc extrusion after falling of 8 meters height. The patient underwent surgical decompression and reduction with instrumentation. Accordingly complete recovery of neurologic deficit was occurred. Therefore, early decompression of the nerve roots followed by circumferential instrumentation and fusion of the involved segment results in dramatic improvement in neurologic symptoms.

Does Mobility of the Elderly with Hip Fractures Improve at One Year Following Surgery? A 5-year Prospective Survey.

BACKGROUND: Hip fracture and its consequences are one of the major causes of morbidity and disability in the elderly. The purpose of this study was to collect epidemiologic data and assess the daily activities and walking ability of patients 3 months and 1 year following surgery because of a hip fracture. MATERIAL AND METHODS: We prospectively obtained data of all consecutive patients more than 50 years of age with any type of hip fracture from 2008 to 2013. After excluding pathologic fractures, hip fracture dislocations, non-surgically treated cases, and dead patients, functional status of the subjects at 3 months and 1 year after surgery was evaluated using a 10-degree scale of pain, modified Barthel index of daily activity, and independent walking ability. RESULTS: In total, 1015 cases were enrolled. Mean age was 75.6 year with a female to male ratio of 1.33. Left-sided hip fractures were seen in 51.7 % of cases. Intertrochanteric fractures were the most common type (72.1 %), followed by femoral neck (24.0 %) and subtrochanteric fractures (3.9 %). At both 3-month and 1-year follow-up visits, 562 subjects (317 women and 245 men) completed the questionnaires. Activities of daily living and independent walking ability were improved significantly at 1 year and the improvements were statistically superior to the results obtained at 3 months (p-value < 0.001 for both variables). CONCLUSION: By continuing rehabilitation of elderly patients with surgically-treated hip fractures for one year, improvement in activities of life and walking independence can be expected even if they have a poor result after the first 3 months of rehabilitation.
