Arthroscopic hip surgery is increasingly common in Australia. Hip arthroscopy is indicated for a range of diagnostic and therapeutic purposes, including
Background. Magnetic resonance arthrography is the current method of choice for investigating patients with a clinical diagnosis of femoroacetabular impingement prior to performing hip arthroscopy. The aim of our study was to assess the efficacy of this investigation by comparing the findings of MR arthrogram with those found at arthroscopy, with reference to
Over half of postpartum women experience pelvic ring or hip pain, with multiple anatomic locations involved. The sacroiliac joints, pubic symphysis, lumbar spine and pelvic girdle are all well documented pain generators. However, despite the prevalence of postpartum hip pain, there is a paucity of literature regarding underlying soft tissue intra-articular etiologies. The purpose of this systematic review is to document and assess the available evidence regarding underlying intra-articular soft tissue etiologies of peri- and postpartum hip pain. Three online databases (Embase, PubMed and Ovid [MEDLINE]) were searched from database inception until April 11, 2021. The inclusion criteria were English language studies, human studies, and those regarding symptomatic labral pathology in the peri- or postpartum period. Exclusion criteria were animal studies, commentaries, book chapters, review articles and technical studies. All titles, relevant abstracts and full-text articles were screened by two reviewers independently. Descriptive characteristics including the study design, sample size, sex ratio, mean age, clinical and radiographic findings, pathology, subsequent management and outcomes were documented. The methodological quality of the included studies was assessed using the Methodological Index for Non-Randomized Studies (MINORS) instrument. The initial search identified 2472 studies. A systemic screening and assessment of eligibility identified 5 articles that satisfied the inclusion criteria. Twenty-two females were included. Twenty patients presented with labral pathology that necessitated hip arthroscopy with labral debridement or repair with or without acetabuloplasty and/or femoroplasty. One patient presented with an incidental
Since its creation, labral repair has become the preferred method among surgeons for the arthroscopic treatment of acetabular
Purpose. Rectus femoris avulsion (RFA) injuries in paediatric patients are currently managed conservatively. However, the proximal attachment of the rectus femoris muscle lies in a critical zone in the hip joint with attachments to the anterior hip capsule and anterior inferior iliac spine. Violent avulsions therefore could cause damage to the adjacent acetabular labrum and articular cartilage initiating a process leading to early degenerative changes in the hip. To date, the association between rectus avulsions and
We present to you a match-controlled study assessing co-existing arthroscopic findings during hip arthroscopy in patients with an intraoperative diagnosis of a central acetabular osteophyte (CAO). We feel that this manuscript is both pertinent and timely. Recent literature has described the entity of central acetabular impingement, in which an osteophyte of the cotyloid fossa impinges against the superomedial femoral head and fovea. The technique for central acetabular decompression has also been described to treat this entity. The primary purpose of this study was to report the prevalence of femoral head articular damage in a matched cohort of patients with and without central acetabular osteophyte (CAO) that was identified during hip arthroscopy. A secondary purpose was to identify the rates of co-existing intraarticular pathology in both patient groups. Intraoperative data was collected prospectively on all patients undergoing hip arthroscopy at our institution between February 2008 to March 2015,. The inclusion criteria for this study were the presence of a CAO identified during hip arthroscopy for a
The management of shoulder instability has changed a great deal in the last five years due to a better understanding of the biomechanics of the shoulder and the use of arthroscopic surgery. It is essential to understand the anatomy of the labrum and bony structures of the shoulder joint, as well as the contribution of these structures as well as the Rotator Cuff to stability in the different positions of the arm. The history and examination still remains the most important diagnostic tool and a thorough history and examination cannot be over-emphasised. MR Arthrography is the investigation of choice in confirming the diagnosis of instability while a CT scan may be required if there is significant bony damage. The most controversial topic is that of the first time dislocator. If there is a significant
In previously published work, MR arthrogram (MRA) has sensitivities and specificities of 88–100% and 89–93% respectively in detection of glenoid labrum tears. Our practice suggested higher frequency of falsely negative reports. We aimed to assess accuracy of this costly modality in practice. We retrospectively reviewed MRA reports of 90 consecutive patients with clinical shoulder instability who had undergone arthroscopy. All had history of traumatic anterior dislocation and had positive anterior apprehension tests. All underwent stabilisation during the same procedure. We compared the findings, using arthoscopy as gold standard in identification of glenoid
Aim. The aim of this study was to assess the role of hip arthroscopy in the management of hip pain in elite athletes. Patients and methods. It is a retrospective study of prospectively collected data. 31 hip arthroscopies were performed on 27 elite athletes. All the patients were assessed pre-operatively with a thorough clinical examination, radiographs and MRI scans. The modified HHS was also recorded for all the patients' pre and post-operatively. All operations were performed by the senior author, and the patients were assessed at 6 weeks, 3 months, 6 months and a year following the operation. Results. The M:F ratio was 25:2 with an average age of 38 years (Range: 18-58) in the study group. 65% of the patients were professional football players followed by cricket and tennis. The patients were referred at an average of 506 days. Two of the 27 patients demonstrated minimal acetabular dysplasia on their pre-operative radiographs. Of the 31 arthroscopies, a primary diagnosis of a
Femoroacetabular impingement is defined as abnormal abutment between the femoral head, or the femoral head-neck junction, and the acetabulum. It is now established that FAI is a major etiological factor in the development of osteoarthritis (OA) of the hip. FAI is increasingly recognized as a cause of hip pain in young active individuals. Clinical features of FAI include pain in the groin but this may also be felt in the gluteal region, trochanteric region, or in the thigh. Symptoms most commonly begin as an intermittent discomfort, often during or following periods of repetitive hip motion e.g. running, walking, progressing to more constant and intense pain. Stiffness is common, with reductions in the range of hip flexion, and internal rotation in particular. Patients may also complain of clicking, popping, or snapping sensations in the affected hip. Operative treatment of FAI is principally aimed at removing cam lesions and increasing femoral head-neck offset (osteochondroplasty), and treating associated soft tissue lesions such as
In the young and highly active population of military patients, femoroacetabular impingement can be a source of serious disability as well as a threat to their career. This morbidity can be treated with hip arthroscopy with debridement of cam lesion, and excision or repair of a corresponding
Objective. To define the common pathology of the hips with irreducible posterior dislocation combined with femoral head fracture and the outcome of surgical treatment using surgical hip dislocation technique. Design: retrospective observational clinical study. Setting: Level III referral trauma center. Patients/Participants: from January 2011till February 2014 five patients with irreducible posterior hip dislocation and femoral head fracture who underwent operation were included and they followed for at least 18 months. Intervention. Open reduction and internal fixation of fractured femoral head and labral repair by suture anchors using surgical hip dislocation through trochanteric flip osteotomy approach. Main Outcome Measures: Clinical and radiographical findings of the irreducible posterior hip dislocation, intraoperative findings, clinical outcomes using Merle d'Aubigné & Postel and Thompson & Epstein scores, and radiological outcome. Results. All patients presented clinically with a shortened lower limb in neutral or external rotation of the hip (not in Internal rotation). All were Pipkin type II fracture of femoral head with the intact part of the head buttonholed on the posterior wall of the acetabulum through a capsule-labral flap. Postoperative computed tomography revealed perfect reduction except one case with severe comminution with good reduction. Only one patient with delayed operative management developed avascular necrosis and underwent total hip arthroplasty. Conclusion. Irreducible femoral head fracture-dislocation is rare injury with different clinical presentation that shows neutral or externally rotated limb and optimal surgical management is not clear. Surgical hip dislocation gives full access to the femoral head for reconstruction and opportunity to direct repair of the
There are a number of progressive conditions that afflict the hip and result in degenerative arthritis. Along the path of progression of the disease and prior to the development of arthritis, some of these conditions may be treatable by joint preservation procedures. Periacetabular osteotomy for developmental dysplasia of the hip (DDH), femoroacetabular osteoplasty for femoroacetabular impingement (FAI), and a variety of surgical procedures for management of early osteonecrosis of the femoral head are some examples of joint preservation of the hip. DDH is characterised by abnormal development of the acetabulum and the proximal femur that leads to suboptimal contact of the articular surfaces and the resultant increase in joint reaction forces. FAI is a condition characterised by an abnormal contact between the femoral neck and the acetabular rim. FAI is believed to exist when a triad of signs (abnormal alpha angle,
Introduction. Hypoplasia of the glenoid is a rare condition caused by incomplete ossification of the postero-inferior aspect of the developing glenoid. It may be isolated or associated with a more generalised condition. The clinical symptomatology is variable depending on the age at time of presentation. Materials and Methods. We performed a retrospective chart review of patients who presented with shoulder complaints, and in whom a radiographic diagnosis of glenoid hypoplasia had been made. From January 2002 to December 2012, 8 patients (9 shoulders) with radiological signs of glenoid hypoplasia were identified. The mean age at presentation was 39 years (range 23 to 77) and the mean symptom duration was 12.5 months (range 1 to 48). Results. The diagnoses encountered included: impingement with rotator cuff tendonitis (2 shoulders), rotator cuff dysfunction with biceps tendonitis (1 shoulder), a SLAP lesion (2 shoulders), calcific tendonitis (1 shoulder), a posterior
The purpose of this study was to investigate whether patients who had had excision of the Ligamentum Teres as part of a surgical hip dislocation for femoro-acetabular impingement exhibited symptoms of acute Ligamentum Teres rupture post-operatively. Recent reports in the literature suggest that injury to the Ligamentum Teres can cause instability, severe pain and inability to walk. We present the results of a postal questionnaire to 217 patients who had undergone open surgical hip dislocation for femoro-acetabular impingement where the LT was excised. This included seven patients who had undergone bilateral surgery. The questionnaire was designed to enquire about specific symptoms attributed to LT injuries in the literature; gross instability, incomplete reduction, inability to bear weight and mechanical symptoms. 161 patients responded (75%), with a total of 168 (75%) questionnaires regarding 224 hips completed. There were 104 females and 64 males. Median age was 34 and median follow-up was 52 months. All patients were found to have cam deformities, 72% (n=121) had associated
Introduction. Femoroacetabular impingement (FAI) causes anterior hip pain,
Introduction. Symptomatic neglected and displaced three- and four-part proximal humeral fractures are often difficult to reconstruct. Replacement has been reported to give poor functional outcome and hence is not the ideal treatment option. We report our results of secondary reconstruction of these difficult fractures with a locking plate system. Material and methods. Between 2003 and 2005, 15 healthy active patients with displaced three- to four-part fractures underwent revision/secondary open reduction and internal fixation with a locking plate system (Philos, Stratec UK Ltd). Ten patients had delayed presentation. Three patients had failed previous internal fixation. One patient had non-union and one had malunited fracture. Their average age was 63 years. Objective assessment was measured by the Constant score, subjective assessment by the Oxford questionnaire. The mean follow-up was 14 months. Surgical technique. In revision cases, the fracture was approached through the same incision. All metal work was removed. Careful attention was given to restore the normal anatomy of the humeral head with correct placement of the tuberosities. Reduction was held with Ticron sutures through the rotator cuff followed by fixation with the locking plate. Two patients required arthroscopic repair of their
Background.
Background. The acetabular labrum is an essential stabilizer of the hip joint, imparting its greatest effect in extreme joint positions where the femoral head is disposed to subluxation and dislocation. However, its stabilizing value has proved difficult to quantify. The objective of the present study was to assess the contribution of the entire acetabular labrum to mechanical joint stability. We introduce a novel “dislocation potential test” that utilizes a dynamic, cadaveric, robotic model that functions in real-time under load-control parameters to map the joint space for low-displacement determination of stability, and quantify using the “stability index”. Methods. Five fresh-frozen human cadaveric hips without
The Rotator Cuff Registry is a unique initiative of the New Zealand Shoulder & Elbow Society. The aim of the study was to enrol nationwide all patients undergoing rotator cuff repair over a 22 month period to provide best practice guidelines for management of rotator cuff tears. To qualify for the Registry patients have to undergo surgical repair of either a partial or full thickness rotator cuff tear. Prior to surgery patients fill out a registration document as well as a pain score and Flex-SF function score. The Surgeon completes an operating day questionnaire detailing operative findings and repair methods. Follow-up is by pain and Flex-SF function scores returned at six, twelve and twenty-four months from surgery. By the 31st December 2010 3000 patients had been recruited. Analysis of the first 2684 patients for the purpose of this abstract showed 70% Male and 30% female. The dominant arm was involved in 65%. 19% of patients were in high demand occupations, 27% in medium demand and 33% low demand occupations. 16% of patients were treated with all arthroscopic repair, 40% were mini-open and 44% open. Comparing pre-op and one year post-op activity scores by surgical approach the Flex-SF improved by 12.97 points in the arthroscopic group, 13.3 in the mini-open and 12.72 in the open (NSS). Pre-op, 6 mth and 12mth pain scores were arthroscopic 4.60, 1.81 and 1.57, mini-open 4.34, 2.15 and 1.52 and open 4.82, 2.27 and 1.86. Preoperatively, the open approach had statistically more pain than the mini-open. At 6 months the arthroscopic group had statistically less pain than the open and at twelve months the mini-open had statistically less pain than the open group. For all tear sizes significant improvements in Fex-SF were seen both from preoperative levels to 6 month follow-up and from 6–12 month follow-up. A
