Project description:PurposeTo evaluate the 1-year outcomes of a small patient series following open gluteus medius/minimus repair with human dermal allograft incorporated into the repair construct using a double-row repair.MethodsData from consecutive patients undergoing a superior gluteal reconstruction for massive, irreparable abductor tendon tears with severe tendon loss and atrophy by a single fellowship trained surgeon from January 2018 to May 2019 were collected and analyzed. Baseline demographic data and magnetic resonance imaging were collected preoperatively. Clinical outcomes including Hip Outcome Score-Activities of Daily Living (HOS-ADL), HOS-Sports Subscale (HOS-SS), modified Harris hip score (mHHS), international Hip Outcome Score-12 (iHOT-12), visual analog scale (VAS) pain, and VAS satisfaction were recorded at 1-year postoperatively.ResultsA total of 8 patients underwent open superior gluteal reconstruction for severe hip abductor deficiency. The mean age and body mass index were 62.6 ± 7.3 years and 29.6 ± 5.3 kg/m2, respectively. The majority of patients were female (N = 7, 87.5%). Three (37.5%) patients had undergone previous endoscopic gluteus medius repair and presented for revision surgery. All patients had full-thickness tears with gluteus medius and gluteus minimus involvement. Patients were evaluated at an average of 11.5 ± 1.7 months from the initial surgical intervention and reported a mean HOS-ADL of 82.9 ± 24.3, HOS-SS of 73.2 ± 37.3, mHHS of 83.6 ± 17.1, iHOT-12 of 63.9 ± 27.4, VAS Pain of 30.0 ± 23.1, and VAS Satisfaction of 87.1 ± 17.0. There was no evidence of retears in this patient cohort as defined by physical examination findings and/or corroborating magnetic resonance imaging.ConclusionsSuperior gluteal reconstruction for massive, irreparable abductor tendon tears with severe tendon loss and atrophy is a technique that demonstrates promising 1-year postoperative outcomes in both primary and revision patients.Level of evidenceLevel IV, therapeutic case series.

Project description:Complete avulsion of hip abductor muscles may cause severe gait dysfunction and pain. An open surgical procedure to transfer tendons of the gluteus maximus and the tensor fasciae latae to the greater trochanter to make up for the deficient hip abductor has been proposed. The purpose of this study was to describe an endoscopic procedure to transfer gluteus maximus and the tensor fasciae latae to the greater trochanter for hip abductor deficiency.

Project description:Background: Hip fracture is a common orthopedic condition that leads to many hospitalizations each year. Intertrochanteric femur fractures are commonly treated with cephalomedullary nail fixation. Superior gluteal artery bleed is a rare complication of cephalomedullary nail fixation, especially when the trochanteric approach is used. Case Report: A 63-year-old male presented to the emergency department with a right intertrochanteric femur fracture after a fall from standing height. Cephalomedullary nail fixation was performed without any complications during the operation. The patient's postoperative course was complicated by decreasing hemoglobin levels despite blood transfusions. Superior gluteal artery bleed with a large hematoma was discovered on postoperative day 4. The bleed was embolized, and the patient was stabilized and discharged. Conclusion: We found only 1 published report of a superior gluteal artery bleed associated with nail placement. During the operative procedure, guidewire placement requires careful consideration because of the risk of vascular damage. Superior gluteal artery injury, although rare, should be considered in patients with unstable hemoglobin levels after nail placement.

Project description:Despite a paucity of physiological evidence, simplistic biomechanical analyses have led researchers to assume that humans who have wider hips use more energy to walk. Pitting biomechanical first principles against physiological data has led to little deepening of our understanding of bipedalism and its evolution. Both approaches, however, use proxies for the energy used by muscles. We decided to approach the question directly. Using a musculoskeletal model of the human body that estimates the metabolic energy expenditure of muscle activation for 48 people (23 women), 752 trials were evaluated. Metabolic energy consumption for the abductor muscles was summed over a stride to create total abductor energy expenditure. We calculated the maximum hip joint moment acting in the coronal plane and the functional distance between the hip joint centers. We hypothesize that wider hips would be correlated with both maximum coronal plane hip moment and increased total abductor energy expenditure when mass and velocity were controlled. Linear regressions with multiple independent variables, clustered by participant to control for the non-independence of the data points, were performed in Stata. We found that hip width does not predict total abductor energy expenditure, although mass and velocity combine to predict 61% of the variation (both p<0.001). Maximum hip joint coronal plane moment is predicted by pelvic width (p<0.001) and, in combination with mass and velocity (both p<0.001), explains 79% of the variation. Our results indicate that people use their morphology in ways that limit differences in energy expenditure. Consistent with recent discussion, intraspecific variation might not be useful to understand differences among species.

Project description:Endoscopic repair of hip abductor tendons has been shown to have equivalent outcomes and lower complication rates compared with open repair. First reported in 2007, endoscopic repair has become more frequent, with multiple techniques previously described. Frequently, hip abductor tears involve a partial-thickness undersurface component that has been previously addressed endoscopically by making a longitudinal split in the tendon to access the diseased tissue. However, we present a technique for addressing these undersurface tears in situ, accessing the undersurface of the tear by coming under the distal anterior edge of the gluteus medius tendon.

Project description:PurposeDetermine whether patient pain and function are similar following hip abductor repair in patients without and with total hip arthroplasty (THA).MethodsPatients who underwent hip abductor repair were categorized as to whether they had a THA or not. Pre- and postoperative pain and Harris Hip Score (HHS) were recorded and compared between groups.ResultsThere were no differences in improvement in pain level, improvement in HHS, satisfaction with surgery.ConclusionsHip abductor repair leads to similar pain, function, and satisfaction in patients without and with THA.

Project description:Treatment of postoperative pain in children with cerebral palsy (CP) is a major challenge. We investigated the effect of epidural analgesia, high-volume local infiltration analgesia (LIA), and an approximated placebo control on early postoperative pain in children with CP who were undergoing unilateral hip reconstruction.Between 2009 and 2014, we included 18 children with CP. The first part of the study was a randomized double-blind trial with allocation to either LIA or placebo for postoperative pain management, in addition to intravenous or oral analgesia. In the second part of the study, the children were consecutively included for postoperative pain management with epidural analgesia in addition to intravenous or oral analgesia. The primary outcome was postoperative pain 4 h postoperatively using 2 pain assessment tools (r-FLACC and VAS-OBS) ranging from 0 to 10. The secondary outcome was opioid consumption over the 21-h study period.The mean level of pain 4 h postoperatively was lower in the epidural group (r-FLACC: 0.7; VAS-OBS: 0.6) than in both the LIA group (r-FLACC: 4.8, p?=?0.01; VAS-OBS: 5.2, p?=?0.02) and the placebo group (r-FLACC: 5.2, p?=?0.01; VAS-OBS: 6.5, p?<?0.001). Corrected for body weight, the mean opioid consumption was lower in the epidural group than in the LIA group and the placebo group (both p?<?0.001).Epidural analgesia is superior to local infiltration analgesia for early postoperative pain management in children with cerebral palsy who undergo unilateral hip reconstruction.

Project description:ObjectiveTo investigate the effect of hip abductor fatigue on the kinematics and kinetics of the knee joint during walking in healthy people to provide a new approach for the prevention and treatment of knee-related injuries and diseases.MethodsTwenty healthy participants, ten females, and ten males, with a mean age of 25.10 ± 1.2 years, were recruited. Isometric muscle strength testing equipment was used to measure the changes in muscle strength before and after fatigue, and the surface electromyography (SEMG) data during fatigue were recorded synchronously. The Vicon system and an AMTI© force platform were used to record the kinematic parameters and ground reaction force (GRF) of twenty participants walking at a self-selected speed before and after fatigue. Visual 3D software was used to calculate the angles and torques of the hip and knee joints.ResultsAfter fatigue, the muscle strength, median frequency (MF) and mean frequency (MNF) of participants decreased significantly (P < 0.001). The sagittal plane range of motion (ROM) of the knee (P < 0.0001) and hip joint (P < 0.01) on the fatigue side was significantly smaller than before fatigue. After fatigue, the first and second peaks of the external knee adduction moment (EKAM) in participants were greater than before fatigue (P < 0.0001), and the peak values of the knee abduction moment were also higher than those before fatigue (P < 0.05). On the horizontal plane, there is also a larger peak of internal moment during walking after fatigue (P < 0.01).ConclusionHip abductor fatigue affects knee kinematics and kinetics during normal gait. Therefore, evaluating hip abductor strength and providing intensive training for patients with muscle weakness may be an important part of preventing knee-related injuries.

Project description:IntroductionAdvances in medical science are helping to break down the barriers to surgery. In the near future, neonatal or in utero operations will become the standard for the treatment of defects in the human motor system. In order to carry out such procedures properly, detailed knowledge of fetal anatomy is necessary. It must be presented in an attractive way not only for anatomists but also for potential clinicians who will use this knowledge in contact with young patients. This work responds to this demand and presents the anatomy of the superior gluteal nerve in human fetuses in an innovative way. The aim of this work is to determine the topography and morphometry of the superior gluteal nerve in the prenatal period. We chose the superior gluteal nerve as the object of our study because of its clinical significance-for the practice of planning and carrying out hip surgery and when performing intramuscular injections.Material and methodsThe study was carried out on 40 human fetuses (20 females and 20 males) aged from 15 to 29 weeks (total body length v-pl from 130 to 345 mm). Following methods were used: anthropological, preparatory, image acquisition with a digital camera, computer measurement system Scion for Windows 4.0.3.2 Alpha and Image J (accuracy up to 0.01 mm without damaging the unique fetal material) and statistical methods.ResultsThe superior gluteal nerve innervates three physiologically significant muscles of the lower limb's girdle: gluteus medius muscle, gluteus minimus muscle and tensor fasciae latae muscle. In this study the width of the main trunk of the nerve supplying each of these three muscles was measured and the position of the nerve after leaving the suprapiriform foramen was observed. A unique typology of the distribution of branches of the examined nerve has been created. The bushy and tree forms were distinguished. There was no correlation between the occurrence of tree and bushy forms with the body side (p > 0.05), but it was shown that the frequency of the occurrence of the bushy form in male fetuses is significantly higher than in female fetuses (p < 0.01). Proportional and symmetrical nerve growth dynamics were confirmed and no statistically significant sexual dimorphism was demonstrated (p > 0.05).ConclusionsThe anatomy of the superior gluteal nerve during prenatal period has been determined. We have identified two morphological forms of it. We have observed no differences between right and left superior gluteal nerve and no sexual dimorphism. The demonstrated high variability of terminal branches of the examined nerve indicates the risk of neurological complications in the case of too deep intramuscular injections and limits the range of potential surgical interventions in the gluteal region. The above research may be of practical importance, for example for hip surgery.
