Neurovascular complication hip surgery

Objective: To evaluate the early effectiveness of the robot-assisted total hip arthroplasty (THA) via direct superior approach (DSA). Methods: Between March 2021 and April 2021, 11 patients (11 hips) were treated with a robot-assisted THA via DSA. There were 7 males and 4 females, with an average age of 55 years (range, 26-73 years). There were 5 patients of osteoarthritis secondary to hip dysplasia and 6 patients of osteonecrosis of femoral head. Preoperative hip Harris score was 55...

Hardware breakage during orthopaedic surgery especially closed intramedullary nailing is a nightmare for orthopaedic surgeons. During hip fracture surgery a mechanical failure of the guidewire or the reamer poses an additional risk of intrapelvic migration and neurovascular or visceral injury which can lead to devastating complications and litigation. We report a case of removal of the broken guidewire using a cannulated reamer & discectomy forceps and recommend some suggestions for prevention of this catastrophe...

Vascular injuries sustained during total hip replacements are associated with life- and limb-threatening complications. In the present report, we have described a novel vascular injury of an external iliac artery pseudoaneurysm repaired with an interposition vein graft. The vascular injury had been caused by heat from the curing process of a nearby cement hip spacer. During the curing process of bone cement, in vivo temperatures of ≤70°C can be reached, with such temperatures creating the potential for vascular injury...

PURPOSE: Proper placement of infra-acetabular screws is technically demanding; there is a limited safe zone for screw fixation because of the complexity of the bone anatomy around the hip joint and the vulnerability of the major neurovascular bundles in the pelvic cavity. We aimed to present the obturator hook technique as a surgical technique for infra-acetabular screw placement in acetabular and pelvic fractures and report its radiological outcomes. METHODS: Patients treated with infra-acetabular screw placement using the obturator hook technique between January 2015 and August 2020 were enrolled in this study...

OBJECTIVE: Severe hip osteoarthritis, caused by bone or joint maldevelopment, biomechanical transformation and previous surgical intervention, is inclusively existed in spondyloepiphyseal dysplasia (SED). To investigate and discuss the short-term efficacy and possible effects of total hip arthroplasty in the treatment of Tönnis grade 3 hip osteoarthritis in patients with SED. METHODS: From January 2017 to June 2019, 374 patients with hip osteoarthritis were involved for total hip arthroplasty conducted by senior professional surgeons, of whom 9 patients (6 males and 3 females) with 12 hip osteoarthritis secondary to the SED met the inclusive and exclusive criteria and received the above-mentioned hip operation...

BACKGROUND: Neurovascular injury is a critical complication in total hip arthroplasty (THA). However, neurovascular geographic variations around the hip joint in different body positions have not been examined. This study investigated the differences in hip neurovascular geography in the supine and lateral positions using magnetic resonance imaging (MRI). HYPOTHESIS: The neurovascular geography of the hip is influenced by differences in surgical body position. PATIENTS AND METHODS: This was a single-center prospective study of 15 healthy volunteers enrolled between January 2018 and March 2019...

The anatomic extent of a pelvic bone tumor and the need for reconstruction dictate the type of pelvic resection (limb salvage pelvic resection or amputation). If a pelvic bone tumor resection involves two or more critical anatomic structures (the sciatic nerve, femoral neurovascular bundle or the hip joint), then reasonable functional recovery after limb salvage is less likely and amputation should be considered. Both limb salvage and amputation approaches to the pelvis are technically arduous surgeries with significant associated morbidity and complications...

INTRODUCTION: Acute lower limb ischemia (ALLI) in the pediatric population is rare but may lead to limb loss and life-long complications. We report the technique and outcomes of microsurgical salvage of ALLI in a pre-term newborn after open reduction of congenital hip dysplasia. CASE REPORT: A two months-old girl was born premature at week 36 with congenital bilateral hip dysplasia. The initial management attempted was conservative and entailed placement of bilateral Von Rosen splints...

Although total hip arthroplasty (THA) surgery is one of the most successful procedures in orthopaedics, the number of revision procedures is predicted to increase by 137% over the next two decades.1 Implant failure modes such as instability, infection, loosening, and wear are becoming more prevalent.2 Instability, infection, extensive bony defects, and soft-tissue damage are the most important concerns and complications associated with revision surgery. More than 50% of revisions involve the acetabular implant...

BACKGROUND: Prior reports of hip arthroscopy using a perineal post have established the risks of groin soft tissue injury, sexual dysfunction, and altered lower extremity neurovascular function. These parameters have not been investigated for hip arthroscopy without the use of a perineal post. PURPOSE: To evaluate the effects of postless hip arthroscopy on lower extremity venous blood flow, nerve conduction, muscle tissue damage, and perineal injury. STUDY DESIGN: Case series; Level of evidence, 4...

INTRODUCTION: The aim of this study has been to present outcomes after cementless arthroplasty for developmental dysplasia Crowe type IV of the hip, with transverse subtrochanteric shortening osteotomy and using the S-ROM stem. METHODS: We evaluated radiographs, functional scores and complications in a consecutive series of 23 patients (28 hips) with high dislocation of the hip. The average age of patients at surgery was 49.9 (range 22-68) years. The operations were performed between 2007 and 2013...

BACKGROUND: It is challenging to create an ideal artificial acetabulum during total hip arthroplasty (THA) in adult DDH. Our team developed a new patient-specific instrument (PSI) that uses the superolateral rim of the acetabulum as a positioning mark to assist in the production of an artificial acetabulum in adult Crowe II/III DDH patients. The purpose of this retrospective study is to verify whether this new PSI can be used to implement the preoperative plan accurately and quickly to create an ideal artificial acetabulum during THA in adult Crowe II/III DDH patients...

Objective: To summarize the main methods and comprehensive effects of limited surgery combined with external fixation for the treatment of flail foot with sensory disorder of spina bifida sequela in adult. Method: The clinical data of 22 cases (30 feet) of the adult spina bifida sequela who suffered from flail foot with sensory disorder and treated by limited surgery combined with external fixation were retrospectively analysed between January 2005 and December 2015...

BACKGROUND: The direct lateral approach to THA provides good exposure and is associated with a low risk of dislocations, but can result in damage to the abductor muscles. The direct anterior approach does not incise muscle, and so recovery after surgery may be faster, but it has been associated with complications (including fractures and nerve injuries), and it involves a learning curve for surgeons who are unfamiliar with it. Few randomized trials have compared these approaches with respect to objective endpoints as well as validated outcome scores...

BACKGROUND: Cerclage wires or cables are commonly being used in hip reconstruction procedures like primary (especially in patients with developmental hip dysplasia) or revision arthroplasty. Local or distant migration of a broken cable or wire is a complication that might lead to devastating situations depending on the route of migration. CASE PRESENTATION: We report a case of a 40-year-old female who underwent bilateral total hip arthroplasty surgery due to bilateral developmental hip dysplasia...

OBJECTIVE: To evaluate the manipulation technique and clinical outcome of Tri-Lock bone preservation stem for acetabular protrusion combined with shorten defect of femoral head and neck. METHODS: From January 2013 to December 2015, 10 patients(12 hips) with acetabular protrusion combined with shorten defect of femoral head and neck were treated with total hip arthroplasty(THA) including 5 males and 5 female with an average age of(51.6±3.0) years old ranging from 42...

Introduction: Obesity is an oft-cited cause of surgical morbidity and many institutions require extensive supplementary screening for obese patients prior to surgical intervention. However, in the elderly patients, obesity has been described as a protective factor. This article set out to examine the effect of body mass index (BMI) on outcomes and morbidity after hip fracture surgery. Methods: The National Surgical Quality Improvement Program database was queried for all patients undergoing 1 of 4 surgical procedures to manage hip fracture between 2008 and 2012...

CASE: A patient was struck by an agricultural vehicle and sustained ipsilateral hip and knee dislocations. Closed reduction of the hip was accomplished in the emergency department; the patient required general anesthesia in the operating room to reduce the knee dislocation. Nonoperative treatment was used for both injuries, with a good long-term outcome. CONCLUSION: Simultaneous ipsilateral hip and knee dislocations are rare and complex injuries that usually result from high-energy trauma...

Neurogenic heterotopic ossification of the hip is secondary to neurologic lesions such as cranial trauma, stroke, medullary injury or cerebral anoxia. We shall not deal here with the other etiologies of heterotopic ossification. There are numerous locations within the hip, depending on etiology and relations with adjacent neurovascular structures are sometimes close. Preoperative work-up should include contrast-enhanced CT; scintigraphy is non-contributive. Indications for surgery are decided in a multidisciplinary team meeting, with a contract laying out expected functional gain...

PURPOSE OF THE STUDY This retrospective study aims to present short-term clinical outcomes of endoscopic treatment of patients with greater trochanteric pain syndrome (GTPS). MATERIAL AND METHODS The evaluated study population was composed of a total of 19 patients (16 women, 3 men) with the mean age of 47 years (19-63 years). In twelve cases the right hip joint was affected, in the remaining seven cases it was the left side. The retrospective evaluation was carried out only in patients with greater trochanteric pain syndrome caused by independent chronic trochanteric bursitis without the presence of m...
