Sagittal alignment in patients with flexion contracture of the hip before and after total hip arthroplasty.

INTRODUCTION: In hip osteoarthritis, hip flexion contracture can severely alter the patient's alignment, and, therefore, affect the patient's quality of life (QOL). Hip contracture is not well-studied, partly because of the difficulties of its diagnosis. The aim of this study was to propose a quantitative definition of hip flexion contracture, and to analyse sagittal alignment in these patients compared to non-contracture ones, before and 12 months after total hip arthroplasty (THA). MATERIALS AND METHODS: Consecutive patients with hip arthrosis and an indication for THA were included (N = 123). Sagittal full-body radiographs were acquired in free standing position and in extension. QOL questionnaires were administered before and after surgery. Spinopelvic parameters were measured, including the pelvic-femur angle (PFA). Patients with low pelvic incidence (< 45°) were included in the hip contracture group if PFA > 5°, or PFA > -5° when pelvic incidence ≥ 45°. RESULTS: 29% of patients were in the hip flexion contracture group, and they showed lower pelvic tilt than the no-contracture group (p < 0.001), larger lumbar lordosis (LL) and smaller PI-LL (p < 0.001), as well as a forward position of the head. 16% of patients still had hip contracture 12-months postop. Contracture patients showed higher QOL scores after surgery. CONCLUSIONS: The proposed method to diagnose hip contracture group allowed to define a group of patients who showed a specific pattern of sagittal spinopelvic alignment. These patients improved their alignment and quality of life postoperatively, but their hip mobility was not always restored. Diagnosing these patients is a first step toward the development of more specific surgical approaches, aiming to improve their surgical outcome.

Spinopelvic Compensatory Mechanisms for Reduced Hip Motion (ROM) in the Setting of Hip Osteoarthritis.

STUDY DESIGN: Retrospective review from a single institution. OBJECTIVE: To investigate the effect of hip osteoarthritis (OA) on spinopelvic compensatory mechanisms as a result of reduced hip range of motion (ROM) between sitting and standing. SUMMARY OF BACKGROUND DATA: Hip OA results in reduced hip ROM and contracture, causing pain during postural changes. Hip flexion contracture is known to reduce the ability to compensate for spinal deformity while standing; however, the effects of postural spinal alignment change between sitting and standing is not well understood. METHODS: Sit-stand radiographs of patients without prior spinal fusion or hip prosthesis were evaluated. Hip OA was graded by Kellgren-Lawrence grades and divided into low-grade (LOA; grade 0-2) and severe (SOA; grade 3 or 4) groups. Radiographic parameters evaluated were pelvic incidence (PI), pelvic tilt (PT), lumbar lordosis (LL), PI-LL, thoracic kyphosis (TK), SVA, T1-pelvic angle (TPA), T10-L2, proximal femoral shaft angle (PFSA), and hip flexion (PT change-PFSA change). Changes in sit-stand parameters were compared between LOA and SOA groups. RESULTS: 548 patients were included (LOA = 311; SOA = 237). After propensity score matching for age, body mass index, and PI, 183 LOA and 183 SOA patients were analyzed. Standing analysis demonstrated that SOA had higher SVA (31.1 vs. 21.7), lower TK (-36.2 vs. -41.1), and larger PFSA (9.1 vs. 7.4) (all p < .05). Sitting analysis demonstrated that SOA had higher PT (29.7 vs. 23.3), higher PI-LL (21.6 vs. 12.4), less LL (31.7 vs. 41.6), less TK (-33.2 vs. -38.6), and greater TPA (27.9 vs. 22.5) (all p < .05). SOA had less hip ROM from standing to sitting versus LOA (71.5 vs. 81.6) (p < .05). Therefore, SOA had more change in PT (15.2 vs. 7.3), PI-LL (20.6 vs. 13.7), LL (-21.4 vs. -13.1), and T10-L2 (-4.9 vs. -1.1) (all p < .001), allowing the femurs to change position despite reduced hip ROM. SOA had greater TPA reduction (15.1 vs. 9.6) and less PFSA change (86.7 vs. 88.8) compared with LOA (both p < .001). CONCLUSIONS: Spinopelvic compensatory mechanisms are adapted for reduced hip joint motion associated with hip OA in standing and sitting. LEVEL OF EVIDENCE: Level III.

Two-Stage Treatment for Ankylosing Spondylitis With Severe Hip Contracture.

Ankylosing spondylitis is a progressive inflammatory disease that often involves the hip, causing deformities and dysfunction. Total hip arthroplasty (THA) may be used, but contracture of the hip joint in ankylosing spondylitis makes THA technically difficult and leads to poor efficacy. This retrospective study describes a novel 2-stage surgical treatment for ankylosing spondylitis of the hip and evaluates its efficacy relative to THA alone. Patients with ankylosing spondylitis and severe hip flexion contracture treated between 2011 and 2017 were assigned to either an experimental group or an age-matched control group (n=12 each) based on receiving, respectively, soft tissue release of the hip joint, femoral osteotomy, and supracondylar bone traction (stage I) and THA (stage II) or THA only. Clinical and radiological data included preoperative, postoperative, and follow-up Harris Hip Score and visual analog scale score, hip range of motion, femoral nerve injury, and heterotopic ossification. Both groups had significant corrections after surgery. At the final follow-up, the experimental group had significantly higher Harris Hip Scores and range of motion in extension compared with the control group, significantly more reduction in visual analog scale score, and no femoral nerve injury. The novel 2-stage surgery for patients with ankylosing spondylitis and severe hip flexion contracture is effective for restoring hip function and improving patients' quality of life, having fewer complications than traditional THA alone.

Gluteal muscle fibrosis with abduction contracture of the hip.

PURPOSE: Gluteal muscle fibrosis with hip contracture is a rare condition and causes major disability; literature reports are sparse. The aim of this study is to present, for the first time in Iraq and the region, a case series of gluteal fibrosis and the results of surgical treatment. METHODS: Seven children--six boys and one girl--diagnosed as having gluteal muscle fibrosis with hip contracture, were investigated and treated by open surgical release of fibrotic bands and physiotherapy. RESULTS: All patients improved dramatically over the subsequent weeks, and were able to sit and squat in the normal position. CONCLUSIONS: Gluteal muscle fibrosis with hip contracture is present in Iraq and more awareness is needed for early diagnosis. Surgical treatment provided excellent results. More studies are needed to delineate the aetiology of the condition.

Pathological trunk motion during walking in children with amyoplasia: is it caused by muscular weakness or joint contractures?

The aim was to investigate the causes for pathological trunk movements during gait in children with Amyoplasia. Eighteen children with Amyoplasia were compared with 18 typically developed children. Three-dimensional motions of pelvis, thorax and spine during gait were analyzed. Excessive trunk movements were defined as being above 4 standard deviations of those of typically developed children. Clinical examination of active strength and passive range of motion of the hip, knee and ankle joints were correlated to the parameter that showed the greatest prevalence of pathological trunk motion. The greatest prevalence of 56% was seen for thorax obliquity range during walking. The spine angles showed the lowest deviations from typically developed children. Significant correlations (p<0.001) between thorax obliquity range and clinical parameters were found for passive hip extension, hip flexion, hip abduction and active hip extension, hip flexion and ankle dorsiflexion strength. The highest correlation coefficients were found for passive hip flexion and active hip flexion strength of rho=-0.73 and rho=-0.69 respectively. Excessive thorax obliquity during gait in children with Amyoplasia could be mainly caused by reduced strength and mobility of the hip. Therefore both mobility and strength of the hip are equally important and should be increased in the therapy to improve gait in children with Amyoplasia.

La cirugía de estas fracturas, a pesar de los avances de los últimos años en cuanto a las técnicas quirúrgicas y anestésicas, a la generalización de la profilaxis tromboembólica y a unos mejores cuidados médicos, continúa siendo un procedimiento de alto riesgo en cuanto a morbilidad y mortalidad (AU)

Hip fractures in the elderly is a health problem of first magnitude, with an incidence which is increasing exponentially. The surgery of these fractures, despite progress in recent years in terms of surgical and anesthetic techniques, the widespread use of thromboprophylaxis and better medical cares, remains a high risk procedure in terms of morbidity and mortality (AU)

Aracnodactilia contractural congénita / Congenital contractural arachnodactyly

La aracnodactilia contractural congénita (ACC) es un trastorno del tejido conectivo debido a una mutación autosómica dominante. La persona afectada de ACC presenta múltiples expresiones clínicas, incluidas las cardiacas y, principalmente, las musculoesqueléticas. Los progresos en el control de la gestación y la accesibilidad a técnicas de reproducción asistida llevan, cada vez más, a tener que atender situaciones como el caso clínico que se presenta: una gestación gemelar bicorial biamniótica obtenida por técnica de fertilización in vitro en una mujer afectada de dicha enfermedad. Los retos diagnósticos, las alternativas terapéuticas, el pronóstico materno y neonatal y las repercusiones sociales y éticas de estos casos son temas para la reflexión(AU)

Congenital contractural arachnodactyly (CCA) is a connective tissue disorder caused by an autosomal dominant mutation. Affected individuals show multiple involvement, including cardiac and, mainly, musculoskeletal abnormalities. Because of advances in pregnancy management and access to assisted reproduction techniques, situations such as that reported in the present article will become more frequent: we describe a dichorionic diamniotic twin gestation obtained by in vitro fertilization in a woman with CCA. The diagnostic challenges, therapeutic alternatives, maternal and neonatal outcomes, and the social and ethical repercussions of these cases are discussed(AU)

[Psoas abscess with hip contracture in a patient with Crohn's disease].

A psoas abscess (PA) is a rare clinical entity but is potentially serious condition which presents diagnostic and therapeutic challenges. The diagnosis is frequently delayed due to its variable and nonspecific features and occult clinical course. The delay in diagnosis and treatment of PA is the major poor prognostic factor. We describe herein a case of the sterile psoas abscess complicating Cronh's disease which presented as hip flexion contracture. A 29-year-old man, at remission stage of CD involving ileocolic segment, was admitted due to pain from hip contracture. He had no bloody diarrhea and no abdominal pain. PA was confirmed by abdominal ultrasound. PA with hip contracture was completely treated with surgical excision, irrigation, drainage, and antibiotics. PA was sterile and there was no evidence of a fistulous communication from the bowel. Once suspected, aggressive diagnostic work up and definitive operative intervention is needed.

Bilateral hip reconstruction in severe whole-body cerebral palsy: ten-year follow-up results.

The results of a functional, clinical and radiological study of 30 children (60 hips) with whole-body cerebral palsy were reviewed at a mean follow-up of 10.2 years (9.5 to 11). Correction of windsweep deformity of the hips was performed by bilateral simultaneous combined soft-tissue and bony surgery at a mean age of 7.7 years (3.1 to 12.2). We were able to recall 22 patients; five had died of unrelated causes and three were lost to follow-up. Evaluation involved interviews with patients/carers and clinical and radiological examination. The gross motor functional classification system was used to assess overall motor function and showed improvement in seven patients. Of the 12 patients thought to have pain pre-operatively, only one had pain post-operatively. Improved handling was reported in 18 of 22 patients (82%). Those with handling problems were attributed by the carers to growth of the patients. All patients/carers considered the procedure worthwhile. The range of hip movements improved, and the mean windsweep index improved from 50 pre-operatively to 36 at follow-up. The migration percentage and centre-edge angle were assessed on plain radiographs. Radiological containment improved, the mean migration percentage improved from 50 pre-operatively to 20 at follow-up and the mean centre-edge angle improved from -5 degrees to 29 degrees . No statistical difference was noted between the three-year and ten-year follow-up results, indicating that the improvements in clinical and radiological outcome had been maintained.

[Primary abductor hip contracture as diagnostic, prognostic and therapeutic problem in child hip pathology].

Coxa obliqua represents a special functional entity in the pathology of the child hip. Authors have confirmed the results of S.L. Weissman and B. Strinovic which claimed that the abductor contracture of the hip was a primary congenital condition that developed as a result of intrauterine malposition, leading later to the contralateral adductor contracture. Critical period for the development of complications was between 6 and 8 month after birth, adductor contracture might keep persisting together with the development of acetabular dysplasia, and later on with ipsilateral subluxation. This malformation has usually been diagnosed within 3 and 6 months of age. It could be connected with some other signs of malposition, such as plagiocephaly, torticollis or infantile thoracic C scoliosis. For the diagnosis of coxa obliqua, the examination of hips in the prone position was very important and the ultrasonic and radiological examinations were crucial. The applied treatment used to be exclusively physical rehabilitation. Wide diapering has been contraindicated. In this study, we included 2,500 newborns, 1,300 boys and 1,200 girls (5,000 hips). In 22 cases of coxa obliqua (10 per thousand), the excellent results were obtained in 96% of cases. In two unsuccessfully treated cases, a contralateral dysplasia developed, and in one untreated, subluxation. The authors are advocating a systematic and early detection and treatment of the primary coxa obliqua.

[Diagnosis and treatment of gluteal muscle contracture associated with unequal leg length caused by pelvis obliquity].

OBJECTIVE: To investigate the pathogenesis, diagnosis, and treatment of the gluteal muscle contracture associated with an unequal leg length caused by the pelvis obliquity (GMC-PO). METHODS: The retrospective analysis was made on the clinical features and the follow-up results in 132 patients who had been admitted from January 1990 to December 2004 for GMC-PO. Among them, 73 were male and 59 were female with a range in age from 5 to 26 years (average, 11 yr). All the patients were characterized by unsymmetrical contracture of the gluteal muscles, including unilateral and bilateral contracture. Of the patients, 89 had a clear limping and 78 had a clearly-unequal leg length. The X-ray examination revealed pelvis obliquity in 97 cases and an increased angle of the femur neck in 11 cases. The arc longitudinal incision was made into the posterolateral area nearby the greater trochanter and then lysis of the gluteal muscles was performed, combined with the skin traction of both legs and exercise training. RESULTS: Of the 132 patients with unequal gluteal muscle contracture before operation, 13 had a relative length difference of 0.5-1.5 cm between the 2 legs, 1 had a difference of 3.0 cm, and the remaining 118 patients had an equal leg length. Excellent and good results were achieved in 118 and 13 patients, respectively after the surgical release of the gluteal muscle contracture by the arc longitudinal incision into the posterolateral area nearby the greater trochanter, combined with postoperative skin traction and functional exercises. Only 1 patient had a poor result. The follow-up for 3 months to 14 years showed that the cure rate was as high as 99.2%. CONCLUSION: The gluteal muscle contracture associated with an unequal leg length caused by the pelvis obliquity is a result of the unequal gluteal muscle contracture between the 2 hips and it can be cured with a comprehensive therapeutic method including the surgical release of the gluteal muscle contracture by the are longitudinal incision into the posterolateral area nearby the greater trochanter, and postoperative skin traction as well as the functional exercise.

Treatment of lateralisation and subluxation of the hip in cerebral palsy with Botulinum toxin A: preliminary results based on the analysis of migration percentage data.

It has been reported that cerebral palsy patients with adductor spasm and lateralisation/subluxation of the hip can be treated with Botulinum toxin A, but statistical evaluation is lacking. We present the radiological results in 5 patients. The follow-up ranged from 18 (5 patients) to 24 months (4 patients). Reimers' migration percentage was chosen as parameter for lateralisation/subluxation. Statistical analysis was performed by the Wilcoxon test. The migration percentage improved from 51% to 44% at 9 months, 37% at 18 months, and 34% at 24 months. The improvement was significant from the 9th to the 18th month (p=0.04).

[Contractures and growth disturbances in the hip and pelvis as the cause of "idiopathic scoliosis". Biomechanical considerations]. / Przykurcze i zaburzenia rosniecia w obrebie biodra i miednicy przyczyna rozwoju tzw. "skolioz idiopatycznych". Rozwazania biomechaniczne.

Author's own observations on etiology of "idiopathic scoliosis" in children and adolescents are presented. Abduction or flexion-abduction contracture of the hip, mainly right one, is the chief cause of "idiopathic scoliosis". Scoliosis is the final deformity in the chain of malformations commencing in newborns and infants, known as "contracture syndrome". This condition is described by many authors, Mau and Green-Griffin were the first ones. Adduction contracture of the left hip leads to secondary dysplasia of this joint. Coexisting abduction contracture of the right hip is usually neglected. Insufficient adduction in the right hip in extension causes functional elongation of the right extremity and oblique positioning of the pelvis, thus initiating left hand side lumbar, thoraco-lumbar or lumbo-sacral scoliosis. As the next step thoracic scoliosis develops. Early and late clinical and radiographic symptoms are presented, prophylactics and treatment is discussed.

A new case of Ullrich's disease.

A new case of congenital, hypotonic-sclerotic muscular dystrophy is presented. The patient showed congenital hyperlaxity and looseness of distal joints, muscle weakness, and spur-like protrusion of the calcaneus. Afterwards rapid progressive contractures of both knees and hip joints developed. Muscle biopsies revealed unequivocal dystrophic abnormalities and small atrophic fibers with numerous foldings of basal lamina suggestive of a neurogenic lesion. The disease presents clinical variability but the diagnosis is possible when a newborn shows: no dominant family history, slender body, marked distal joint laxity and hyperflexibility, proximal joint contractures and normal or slightly increased serum enzymes.

For whom the bells knell.

A 72-year-old widowed woman known to have an organic brain syndrome was hospitalised owing to gangrene of her lower limbs. The gangrene had been caused by an adduction contracture of her hip resulting in pressure on the medial surface of her left leg. In addition she had pressure sores over both trochanters and the sacrum. The smell of putrefication could be sensed from a distance and on examination large white worms could be seen slithering in the decomposing tissue. The patient was pyrexial, oblivious of her surroundings, and without pain. Surgery--limb amputations--would not restore the patient to a cognitive state nor improve here quality of life, but abstinence posed an inherent threat of sepsis, and revulsion to the attendants. The sacral pressure sore was so large that surgical closure was impossible. The question of surgical intervention is discussed.
