A holistic approach for severe flexion contracture of bilateral hip, knee, and ankle joints in a neglected patient with prolonged knee-chest positioning on extreme undernourishment: a case report and review of the literature.

BACKGROUND: Flexion contracture in the lower extremity is a common finding in the patient with neuromusculoskeletal disorders. However, severe cases due to prolonged immobilization in knee-chest position are rarely established and remain underreported. This condition is associated with high morbidity and reduced quality of life, especially when it comes to neglected cases with missed injury and late presentation for adequate primary care and rehabilitative program. It remains a difficult challenge to treat, with no established treatment protocol. In addition, other factors related to psychological and socioeconomic conditions may interfere and aggravate the health state of such patients. CASE PRESENTATION: A 19-year-old Javanese man presented with flexion contracture of bilateral hip, knee, and ankle joints due to prolonged immobilization in knee-chest position for almost 2 years following a traffic accident and falling in the bathroom. The condition had persisted for the last 3 years due to irrecoverable condition and lack of awareness. In addition, the patient also presented with paraplegia at level L2-S1, dermatitis neglecta, multiple pressure ulcers, community-acquired pneumonia, and severe malnutrition. Prolonged and sustained passive stretching with serial plastering were performed in the patient. By the time of discharge, patient was able to move and ambulate using wheelchair. Progressive improvement of range of motion and good sitting balance were observed by 3-month follow-up. CONCLUSION: A combination of surgery and rehabilitative care is required in the setting of severe flexion contracture. Passive prolonged stretching showed a better outcome and efficacy in the management of flexion contracture, whether the patient undergoes surgery or not. However, evaluation of residual muscle strength, changes in bone density and characteristic, and the patient's general and comorbid conditions must always be considered when determining the best treatment of choice for each patient to achieve good outcome and result. A holistic approach with comprehensive assessment is important when treating such patients.

Cephalic version by postural management in the lateral position without the knee-chest position for primiparous breech presentation: A retrospective cohort study.

AIM: This study aimed to determine the efficacy of postural management in the lateral position for primiparous breech presentation. METHODS: A retrospective cohort study was conducted at a single institution from January 2020 through December 2020. Participants were singleton primiparous pregnant women diagnosed with breech presentation between 28 + 0 and 29 + 6 weeks of gestation. The exclusion criteria were scheduled cesarean delivery, uterine malformation, transverse position, and scheduled delivery at another hospital. A doctor instructed the women in the intervention group to lie on their right sides several times a day if the fetal back was on the left side or lie on their left sides if the fetal back was on the right side. The knee-chest position and other methods were not recommended. The control group received expectant management care. The primary endpoint was the percentage of fetuses in a cephalic presentation 2 weeks later. RESULTS: Of the 56 women included in the study, 17 women were instructed to lie in the lateral position, and 39 women received expectant management care only. After 2 weeks, women who were instructed to lie in lateral position had a higher rate of fetal cephalic version than the control group (82.4% [14/17] vs. 43.6% [17/39], p = 0.017). No study participants experienced adverse effects. CONCLUSIONS: Two weeks of postural management in the lateral position without the knee-chest position significantly reduced the rate of primiparous breech presentation in the third trimester of pregnancy.

[Diagnosis and treatment of superior mesenteric artery compression syndrome secondary to chronic constipation (Lee's triad syndrome)].

Objective: To summarize the experience of diagnosis and treatment of superior mesenteric artery compression syndrome (SMACS) secondary to chronic constipation according to the concept of Lee's triad syndrome. Methods: The concept of Lee's triad syndrome: (1) clinical symptoms: triad of constipation, malnutrition, upper gastrointestinal obstruction (vomiting, difficulty in eating); (2) anatomical manifestations: with triple anatomy anomaly of transverse colon sagging, elevated spleen flexure, and mesentery arterial compression; (3) treatment: with triple treatment of enteral nutrition support, chest-knee posture and fecal microbiota transplantation. A descriptive cohort study was performed. According to Lee's triad syndrome criteria, clinical data of 78 patients with superior mesenteric artery compression syndrome secondary to chronic constipation in the Tenth People's Hospital of Tongji University and General Hospital of Eastern Theater Command from June 2004 to November 2018 were prospectively collected, including basic information, symptoms and signs, imaging findings, nutritional indicators, gastrointestinal quality of life index (GIQLI) and Wexner defecation score. The above parameters based on Lee's triad syndrome criteria were followed up and recorded at 1, 3, 6, 12 months after comprehensive treatment. Results: All the patients had Lee's triple symptoms of constipation, malnutrition, upper gastrointestinal obstruction (vomiting, eating difficulties), and triple anatomy anomaly of transverse colon sagging, elevated spleen curvature, and mesentery arterial compression before treatment. After triple treatment of enteral nutrition support, chest-knee posture, and fecal microbiota transplantation, 69 (88.5%) patients had a significant improvement of symptoms, and 9 patients had no significant improvement of symptoms and then eventually received surgery. The 69 cases without operation received follow-up for 12 months. All the patients eventually returned to normal eating, and upper gastrointestinal angiography and superior mesenteric artery imaging showed duodenal compression disappeared. After 1 month, the constipation-related indexes were improved. After 12 months, the number of autonomous defecation per week increased from 1.0±0.8 to 5.0±1.6 (P<0.001). The GIQLI score increased from 52.7±8.5 to 93.2±7.5 (P<0.001), and the Wexner score decreased from 19.1±2.5 to 6.2±2.1 (P<0.001). After 1 month, nutritional indexes were improved gradually. After 12 months, the BMI increased from (17.9±1.8) kg/m(2) to (21.0±1.3) kg/m(2), total protein increased from (65.2±5.7) g/L to (68.3±4.2) g/L, albumin increased from (32.1±5.1) g/L to (40.4±3.0) g/L, prealbumin increased from (163.2±53.7) mg/L to (259.1±45.6) mg/L, fibrinogen increased from (1.9±0.5) g/L to (2.4±0.5) g/L, whose differences were statistically significant (all P<0.001). Upper gastrointestinal angiography and superior mesenteric artery imaging showed duodenal compression were relieved. The angle between superior mesenteric artery and abdominal aorta increased from (17.4±3.8)° to (37.8±5.8)° (t=-22.26, P<0.001). Conclusion: When patients with SMACS secondary to chronic constipation have Lee's triple symptoms and triple anatomy anomaly, the triple combination treatment of enteral nutrition support, chest-knee posture and fecal microbiota transplantation should be applied.

Propofol TCI Reductions Do Not Attenuate Significant Falls in Cardiac Output Associated With Anesthesia Induction and Knee-Chest Positioning in Spinal Surgery.

BACKGROUND: Induction of anesthesia and the knee-chest position are associated with hemodynamic changes that may impact patient outcomes. The aim of this study was to assess whether planned reductions in target-controlled infusion propofol concentrations attenuate the hemodynamic changes associated with anesthesia induction and knee-chest position. MATERILAS AND METHODS: A total of 20 patients scheduled for elective lumbar spinal surgery in the knee-chest position were included. In addition to standard anesthesia monitoring, bispectral index and noninvasive cardiac output (CO) monitoring were undertaken. The study was carried out in 2 parts. In phase 1, target-controlled infusion propofol anesthesia was adjusted to maintain BIS 40 to 60. In phase 2, there were 2 planned reductions in propofol target concentration: (1) immediately after loss of consciousness-reduction calculated using a predefined formula, and (2) before positioning-reduction equal to the average percentage decrease in CO after knee-chest position in phase 1. Changes from baseline in CO and other hemodynamic variables following induction of anesthesia and knee-chest positioning were compared. RESULTS: Induction of anesthesia led to decreases of 25.6% and 19.8% in CO from baseline in phases 1 and 2, respectively (P<0.01). Knee-chest positioning resulted in a further decrease such that the total in CO reduction from baseline to 10 minutes after positioning was 38.4% and 46.9% in phases 1 and 2, respectively (P<0.01). There was no difference in CO changes between phases 1 and 2, despite the planned reductions in propofol during phase 2. There was no significant correlation between changes in CO and mean arterial pressure. CONCLUSIONS: Planned reductions in propofol concentration do not attenuate anesthesia induction and knee-chest position-related decreases in CO. The knee-chest position is an independent risk factor for decrease in CO. Minimally invasive CO monitors may aid in the detection of clinically relevant hemodynamic changes and guide management in anesthetized patients in the knee-chest position.

Laryngeal Mask Ventilation During Lumbar Spine Neurosurgery in Knee-Chest Position is Feasible.

BACKGROUND: This study describes our experience with laryngeal mask (LM) inserted after anesthetic induction in patients already in knee-chest position for lumbar neurosurgery. METHODS: Airway management (need for LM repositioning, orotracheal intubation because of failed LM insertion), anticipated difficult airway, and airway complications were registered. Statistics were compared between groups with the t test or the χ test, as appropriate. RESULTS: A total of 358 cases were reviewed from 2008 to 2013. Tracheal intubation was performed in 108 patients and LM was chosen for 250 patients (69.8%). Intubated patients had a higher mean age and rate of anticipated difficult airway; duration of surgery was longer (P<0.001, all comparisons). LM insertion and anesthetic induction proved effective in 97.2% of the LM-ventilated patients; 7 patients (2.8%) were intubated because of persistent leakage. Incidences with airway management were resolved without compromising patient safety. CONCLUSION: LM airway management during lumbar neurosurgery in knee-chest position is feasible for selected patients when the anesthetist is experienced.

Therapeutic results of abdominoperineal resection in the prone jackknife position for T3-4 low rectal cancers.

OBJECTIVE: To evaluate the therapeutic results of abdominoperineal resections in the prone jackknife position for T3-4 low rectal cancers. METHODS: From January 2002 to January 2011, 536 patients with T3-T4 low rectal cancer underwent abdominoperineal resection. Two hundred forty-three were treated in the Lloyd-Davies position and 293 in the prone jackknife position. Clinicopathological data and survival of the two groups were analyzed retrospectively. RESULTS: Abdominoperineal resections in the prone jackknife position group were associated with significantly less blood loss (124 ± 50.68 vs 210.67 ± 83.32 ml, P < 0.001) and shorter operation times (3.10 ± 1.08 vs 3.82 ± 1.43 h, p = 0.010) than those in Lloyd-Davies position group. The total local recurrence rate is 8.4 % (45/536). The local recurrence rate in the prone jackknife position group was significantly lower than in the Lloyd-Davies position group (5.5 vs 11.9 %, P < 0.001). By multivariate regression analysis, depth of tumor invasion (P = 0.032), CRM (P < 0.001), and position (P = 0.015) were found to be independent risk factors for local recurrence. Multivariate Cox regression survival analysis, lymph node metastasis, and CRM (P < 0.001) were proven to be the major independent prognostic factors for T3-T4 low rectal cancer patients. CONCLUSIONS: Abdominoperineal resection in the prone jackknife position for T3-T4 low rectal cancers is feasible and has a lower local recurrence.

Bilateral gluteal compartment syndrome and severe rhabdomyolysis after lumbar spine surgery.

Gluteal compartment syndrome (GCS) is an extremely rare and potentially devasting disorder, most commonly caused by gluteal muscle compression in extend periods of immobilization. We report a 65-year-old obese man with hypertension, diabetes mellitus type 2 and hypercholesterolemia underwent lumbar spine surgery in knee-chest position because of degenerative lumbar stenosis. Perioperative hypotension occurred. After surgery, the patient developed increasing pain in the buttocks of both sides and oliguria with darkened urine. Stiffness, tenderness and painful swelling of patients gluteal muscles of both sides, high creatine phosphokinase level, myoglobulinuria and oliguria led to diagnosis of bilateral GCS, complicated by severe rhabdomyolysis (RM) and acute renal failure. In conclusion, obese patients with vascular risk factors and perioperative hypotension may be at risk for developing bilateral GCS and RM when performing prolonged lumbar spine surgery. Early diagnosis and treatment is important, as otherwise, the further course may be fatal.

Lumbar microdiscectomy with spinal anesthesia: comparison of prone and knee-chest positions in means of hemodynamic and respiratory function.

STUDY DESIGN: Prospective clinical study to compare the physiologic changes in lumbar disc surgery regarding to positions. OBJECTIVE: To compare the perioperative hemodynamic and respiratory functions between prone and knee-chest positions for lumbar disc surgery under spinal anesthesia. SUMMARY OF BACKGROUND DATA: Spinal anesthesia is a safe but rarely used alternative to general anesthesia for lumbar disc surgery. It reduces blood loss, avoid pressure necrosis, and nerve injuries, and it provides a more comfortable postoperative period. Prone and knee-chest positions are mostly used positions in lumbar discectomy; hemodynamic and respiratory effects of spinal anesthesia and the differences between these 2 positions in spinal anesthesia were evaluated in this study, which only been evaluated in general anesthesia. METHODS: Forty-five patients were randomized for lumbar microdiscectomy with spinal anesthesia under either prone position (group 1 n = 22) or knee-chest position (group 2 n = 23). All patients were classified as physical status 1 or 2 according to the American Association of Anesthesiology. Spinal anesthesia was performed with hyperbaric bupivacaine. Perioperative continuous hemodynamics and respiratory function test results were recorded after the spinal anesthesia was performed. RESULTS: Immediately after the spinal anesthesia was performed, both the systolic and diastolic arterial blood pressure values were significantly decreased and heart rates were significantly increased in both groups. Both positions showed significant decrease in forced vital capacity (P = 0.002) and forced expiratory volume in 1 second (P = 0.0015) during the surgery respect to preoperative values. The decrease in peak expiratory flow (P = 0.011) and forced expiratory flow at the 25% of the pulmonary volume (P = 0.011) was significant in knee-chest position respect to prone position. CONCLUSION: In conclusion, spinal anesthesia is appropriate for lumbar disc surgery with respect to the hemodynamic parameters in both prone and knee-chest positions, however, in terms of pulmonary functions, the knee-chest position can cause a restrictive effect. Therefore this position should be used cautiously in higher-risk patients.
