Hip pathology may cause groin pain, referred thigh or knee pain, refusal to bear weight or altered gait in the absence of pain. A young child with an irritable hip poses a diagnostic challenge. Transient synovitis, one of the most common causes of hip pain in children, must be differentiated from septic arthritis. Hip pain may be caused by conditions unique to the growing pediatric skeleton including Perthes disease, slipped capital femoral epiphysis and apophyseal avulsion fractures of the pelvis. Hip pain may also be referred from low back or pelvic pathology. Evaluation and management requires a thorough history and physical exam, and understanding of the pediatric skeleton. This article will review common causes of hip and pelvic musculoskeletal pain in the pediatric population.

Salter's innominate osteotomy may predispose to anterior over-coverage of the acetabulum. Over cover or retroversion has been demonstrated to be a cause of hip pain, impingement and subsequent osteoarthritis. We reviewed the long-term follow up of seventeen skeletally mature hips in sixteen patients who had previously undergone a Salter's osteotomy in childhood. The Salter pelvic osteotomy was performed at a mean average age of 5 years and follow up at a mean average age of 20 years. Patients were assessed by clinical examination for signs of impingement, Harris Hip Score and pelvic radiograph. Acetabular version was evaluated by the relationship between anterior and posterior walls of the acetabulum using templates applied to the pelvic radiograph as described by Hefti. The median acetabular cover averaged 17 degrees of anteversion with 2 patients (12%) demonstrating retroversion, neither of whom, had signs of impingement on examination. The mean average Harris Hip Score was 85 indicating a good outcome at long-term follow-up. We believe acetabular remodelling may occur with age after Salter's innominate osteotomy and have found good results in patients after skeletal maturation. Fears of long-term anterior over-coverage and retroversion with this operation may be unfounded.

Recent reports have demonstrated magnetic resonance imaging (MRI) as a promising technique in detecting articular cartilage lesions of the hip joint. The purpose of our study was to evaluate the diagnostic performance of MRI with gadolinium arthrography in detecting acetabular cartilage delamination in patients with pre-arthritic hip pain. 46 patients (48 hips) underwent surgical dislocation of the hip. Mean age was 38.8 (range 17-56). There were 26 males and 20 females. All patients had Magnetic Resonance Imaging with gadolinium arthrography (MRA) before undergoing open hip surgery where the acetabular cartilage was inspected. Acetabular cartilage delamination on MRA was seen on sagittal images as a linear intra-articular filling defect of low signal intensity >1mm in thickness on T1 weighted images and surrounded by contrast. On MRA all hips had a labral tear confirmed at surgery. At surgery 30 hips had evidence of acetabular cartilage delamination, 4 hips had ulceration and 14 had no articular cartilage damage. The majority of labral tears and cartilage damage were located in the antero-superior quadrant. The sensitivity and specificity of MRA detection of cartilage delamination confirmed at surgery were 97% and 84%, respectively. The positive and negative predictive values of the MRA finding were 90% and 94%, respectively. The presence of the acetabular cartilage delamination represents an early stage of articular cartilage degeneration. When evaluating a young adult with hip pain, labral tears in association with cartilage delamination should be considered. MRA represents an effective diagnostic tool.

Idiopathic transient osteoporosis of the hip is a rare condition that was first described in a series women in their third trimester of pregnancy. The clinical course is usually benign and self-limiting. Magnetic resonance is very useful for the diagnosis. Differential diagnoses include avascular necrosis of the femoral head, septic arthritis of the hip, osteomyelitis, stress fractures, primary or secondary neoplastic processes, and referred pain from the spine or genitourinary tract in pregnant women. The authors present a case of idiopathic transient osteoporosis of the pelvis in a young nonpregnant woman with insidious hip pain with no antecedent infection or trauma.

Pathology of the acetabular labrum plays an increasing role in the treatment of hip pain. Hip arthroscopy has proven its clinical value as a useful procedure for successful treatment of labral tears. Until today, only a few studies have investigated the influence of articular cartilage defects on the clinical outcome of partial arthroscopic labrum resection in a larger patient population. We prospectively evaluated patients with an intraoperatively proven labral lesion/tear without any radiological and arthroscopical sign of a concomitant bony femoroacetabular impingement or hip dysplasia for a minimum postoperative follow-up of 2 years. Cartilage defects were classified according to Outerbridge and divided into two subgroups: Outerbridge < or = 1 and Outerbridge > or = 2, respectively. To evaluate combined results, various established scoring systems (visual analogue scale, modified Harris Hip Score, Larson Hip Score) were used. Out of 54 originally enrolled patients, 50 individuals (29 female, 21 male) with a median age of 33 years (range 15-49) were available for follow-up after a mean of 34 (range 24-48) months. At follow-up, the total study population experienced significant improvement in pain and in the combined evaluation scales (Larson Hip Score/MHHS). When patients were categorized into two subgroups, either with intraoperatively present or absent articular cartilage defects, our data indicated that subjects with no degenerative changes of the articular cartilage surface significantly improved in the applied clinically scoring systems. In contrast, in patients with an articular cartilage lesion during hip arthroscopy score values had a tendency to be unimproved or even deteriorated at follow-up. Regression analysis revealed a significant negative correlation between postoperative outcome and the grading of the coexistent articular cartilage defect. On the basis of our investigation, we conclude that partial arthroscopic resection of a torn labrum without attending bone deformity (dysplasia or femoroacetabular impingement) can reveal good and satisfied results. Depending on the extent of a coexisting articular cartilage defect subjective clinical results are compromised.

Lesions to articular cartilage can be difficult to treat and directly impact surgical outcome in hip arthroscopy. This article describes a direct cartilage suture repair technique for a young, active individual with full-thickness acetabular cartilage delamination. Lesions of this type are commonly seen with femoroacetabular impingement. A 17-year-old boy presented with bilateral hip pain greater in the right than left. Arthroscopic intervention for the right hip included direct cartilage repair for the cartilage lesion, osteoplasty for femoroacetabular impingement, repair for an anterior labral tear, capsular plication for iliofemoral ligament laxity, and psoas lengthening. Twelve weeks postoperatively, a standard capsular plication, osteoplasty, and chondroplasty were performed on the left hip. At follow-up, the patient reported feeling 95% normal. He noted that the right and left hips were essentially the same. Symptoms consisted of stiffness after prolonged sitting and mild pain following sports. The patient reported being pain free 90% of the time, with pain 2/10 at worst. He scored a 96 on the modified Harris Hip Score, 93 on the Hip Outcome Score Activities of Daily Living subscale, and 81 on the Hip Outcome Score Sports subscale. Overall, the patient was satisfied with the outcome. The direct cartilage repair, in addition to osteoplasty, anterior superior labral repair, iliofemoral capsular plication, and psoas lengthening, produced an excellent outcome in this young, active patient.

This article describes a rare case of primary synovial chondromatosis of the hip associated with classical femoroacetabular impingement. A 38-year-old man presented with left hip pain of 3 years' duration and range of motion (ROM) limitations. Flexion abduction external rotation and impingement tests were positive and preoperative Harris Hip Score was 68. Radiographs showed multiple loose bodies, a calcified labrum, and a bump at the head-neck junction. Computed tomography (CT) confirmed the findings. Acetabular overcoverage and the crossing over sign were present. The lateral center edge angle was 48 degrees, acetabular roof angle was +2 degrees, alpha angle was 80 degrees, triangular index was 2 mm more than the radius of the femoral head, and anterior offset was 4.5 mm. Magnetic resonance imaging (MRI) revealed an acetabular labral tear, impaction on the femoral head-neck junction, and mild synovial hypertrophy with no acetabular cartilage damage. Loose body removal along with a total synovectomy, excision of the calcified labrum, and osteochondroplasty of the head-neck junction were performed after safe surgical dislocation. At 6-month follow-up, the patient was doing well with a Harris Hip Score of 96, improved ROM, and negative flexion abduction external rotation and impingement tests. Early diagnosis of synovial chondromatosis and impingement can be made by MRI and CT. Clinically, flexion abduction external rotation and impingement tests are positive in 99% and 97% of cases, respectively. Although arthroscopy management has been described for both the entities separately, it has drawbacks. With an open procedure, debridement of the hip joint and excision of femoral and acetabular impingement deformities are possible at the same time.

Femoroacetabular impingement, also known as hip impingement, is the abutment of the acetabular rim and the proximal femur. Hip impingement is increasingly recognized as a common etiology of hip pain in athletes, adolescents, and adults. It injures the labrum and articular cartilage, and can lead to osteoarthritis of the hip if left untreated. Patients with hip impingement often report anterolateral hip pain. Common aggravating activities include prolonged sitting, leaning forward, getting in or out of a car, and pivoting in sports. The use of flexion, adduction, and internal rotation of the supine hip typically reproduces the pain. Radiography, magnetic resonance arthrography, and injection of local anesthetic into the hip joint confirm the diagnosis. Pain may improve with physical therapy. Treatment often requires arthroscopy, which typically allows patients to resume premorbid physical activities. An important goal of arthroscopy is preservation of the hip joint. Whether arthroscopic treatment prevents or delays osteoarthritis of the hip is unknown.

Lateral sided hip pain frequently presents to the orthopaedic clinic. The most common cause of this pain is trochanteric bursitis. This usually improves with conservative treatment. In a few cases it doesn't settle and warrants further investigation and treatment. We present a series of 28 patients who underwent MRI scanning for such pain, 16 were found to have a tear of their abductors. All 16 underwent surgical repair using multiple soft tissue anchors inserted into the greater trochanter of the hip to reattach the abductors. There were 15 females and 1 male. All patients completed a self-administered questionnaire pre-operatively and 1 year post-operatively. Data collected included: A visual analogue score for hip pain, Charnley modification of the Merle D'Aubigne and Postel hip score, Oxford hip score, Kuhfuss score of Trendelenburg and SF36 scores.Of the 16 patients who underwent surgery 5 had a failure of surgical treatment. There were 4 re ruptures, 3 of which were revised and 1 deep infection which required debridement. In the remaining 11 patients there were statistically significant improvements in hip symptoms. The mean change in visual analogue score was 5 out of 10 (p=0.0024) The mean change of Oxford hip score was 20.5 (p=0.00085). The mean improvement in SF-36 PCS was 8.5 (P=0.0020) and MCS 13.7 (P=0.134). 6 patients who had a Trendelenburg gait pre-surgery had normal gait 1 year following surgery.We conclude that hip abductor mechanism tear is a frequent cause of recalcitrant trochanteric pain that should be further investigated with MRI scanning. Surgical repair is a successful operation for reduction of pain and improvement of function. However there is a relatively high failure rate.

Hip arthroscopy is increasingly used as a tool for evaluating and managing painful hip in active patients. The complex anatomy of the lower back, abdomen, pelvis, and upper thigh can make the diagnosis challenging. A thorough history and physical examination in addition to specific imaging modalities can verify the presence or absence of various intra-and extra-articular disorders of the hip. Although hip pain in athletes is often managed conservatively, specific disorders and injuries are appropriately and successfully treated with hip arthroscopy.
