Prospective same day discharge instrumented lumbar spine surgery - a forty patient consecutive series.

PURPOSE: Outpatient lumbar decompression surgeries have been successfully performed in France for over twenty years, earning acceptance. However, outpatient instrumented lumbar spine procedures and arthroplasties are less documented. This study aimed to evaluate the feasibility, efficiency, and safety of outpatient lumbar instrumented surgery. METHODS: A prospective single-center study involving three experienced surgeons was conducted from September 2020 to September 2021, with a minimum six-month postoperative follow-up. Inclusion criteria comprised patients aged 18 to 75 eligible for same-day discharge, undergoing single-level lumbar spinal fusion or arthroplasty via anterior or posterior Wiltse approach. The primary endpoint was assessing the percentage of successful outpatient discharges (within twelve hours), with secondary endpoints including perioperative/postoperative complications and discharge pain prescriptions in terms of frequency and severity. RESULTS: Forty patients (mean age: 44 years; 16/24 male/female ratio) underwent surgery, including 18 lumbar arthroplasties, twelve ALIF, and ten TLIF procedures. The majority of surgeries were performed at L4-L5 (18 procedures) and L5-S1 levels (22 procedures). 95% (38/40) of patients were successfully discharged within twelve hours, with only two patients discharged the following day. No postoperative hematomas, serious adverse events, or revision surgeries were noted. CONCLUSION: 95% of patients were discharged successfully within twelve hours following outpatient lumbar fusion surgery, with a 100% patient satisfaction rate. Specific technical solutions were not necessary, and oral pain relief sufficed. Patient selection and education, including early pain management, played crucial roles in complication avoidance. This study underscores the safety of outpatient instrumented lumbar spine procedures, leading to cost reduction and expedited recovery.

Soft tissue coverage of war extremity injuries: the use of pedicle flap transfers in a combat support hospital.

PURPOSE: Definitive management of extremity injuries including soft tissue coverage is seldom achieved in battlefield medical treatment facilities due to limited resources and operational constraints. The purpose of this study was to analyse the French Army Medical Service experience performing such reconstructive surgery in a Combat Support Hospital (CSH) in Afghanistan. METHODS: A clinical study was performed in the KaIA (Kabul International Airport) CSH from July 2012 to January 2013. RESULTS: During this period 23 Afghan patients treated for soft tissue coverage of combat-related extremity injuries were included. They totalled 28 extremity injuries including 18 blast trauma (BT) and ten non blast trauma (NBT). Overall, 35 extremity pedicled flaps were performed. There were 26 fasciocutaneous flaps, eight muscle flaps and one composite flap. Soft tissue coverage was achieved on all patients reviewed with a mean follow-up of 59 days. Five postoperative complications occurred including two deep infections, one partial flap necrosis and two flap failures, without difference according to injury mechanism. CONCLUSION: Reconstruction of traumatic soft tissue defect can be achieved in CSHs for local nationals. Pedicle flap transfers provide simple and safe coverage for war extremity injuries in this challenging environment whatever the injury mechanism.

Global analysis of sagittal spinal alignment in major deformities: correlation between lack of lumbar lordosis and flexion of the knee.

INTRODUCTION: It has become well recognised that sagittal balance of the spine is the result of an interaction between the spine and the pelvis. Knee flexion is considered to be the last compensatory mechanism in case of sagittal imbalance, but only few studies have insisted on the relationship between spino-pelvic parameters and lower extremity parameters. Correlation between the lack of lumbar lordosis and knee flexion has not yet been established. MATERIALS AND METHODS: A retrospective study was carried out on 28 patients with major spinal deformities. The EOS system was used to measure spinal and pelvic parameters and the knee flexion angle; the lack of lumbar lordosis was calculated after prediction of lumbar lordosis with two different formulas. Correlation analysis between the different measured parameters was performed. RESULTS: Lumbar lordosis correlated with sacral slope (r = -0.71) and moderately with knee flexion angle (r = 0.42). Pelvic tilt correlated moderately with knee flexion angle (r = 0.55). Lack of lumbar lordosis correlated best with knee flexion angle (r = 0.72 and r = 0.63 using the two formulas, respectively). CONCLUSION: Knee flexion as a compensatory mechanism to sagittal imbalance was well correlated to the lack of lordosis and, depending on the importance of the former parameter, the best procedure to correct sagittal imbalance could be chosen.

How to reconstruct an upper full-thickness abdomen wall defect in austere environment? Interests of the pedicled myofascial latissimis dorsi flap.

Upper abdominal wall defects secondary to trauma are not amenable to immediate closure in most cases. After a primary coverage, the definitive reconstruction can be done at a later date, using prosthetic mesh or flap. The majority of these complex procedures is, however, not available in the austere environment. The authors report a clinical case of upper full-thickness defects of the abdominal wall secondary to an explosion in Afghanistan. The patient was managed by a French Forward Surgical Team. The defect was immediately reconstructed in a one-stage surgery using a pedicled myofascial latissimus dorsi flap with good functional results. The pedicled latissimus dorsi flap is commonly used for coverage of both extrathoracic and intrathoracic defects. It is, therefore, possible to extend the harvesting of the muscle to the thoracolumbar fascia and the posterior third of the iliac crest. It provides a very large flap to cover an upper full-thickness abdomen wall defect. The harvest technique is simple, short, and largely accessible to a general surgeon. It provides immediate and definitive closure with a short hospital stay, what is clearly adapted in austere environment.
