Non-surgical treatment as the first step to manage peritrochanteric space disorders.

PURPOSE: Greater trochanter pain syndrome (GTPS) or lateral hip pain terms include external snapping hip, trochanteric bursitis and gluteus medius or minimus pathology. The aim of this review is to update the most recent knowledge about non-surgical management of peritrochanteric disorders. METHODS: A literature review was performed including articles most relevant in the last years that were focused in non-surgical treatment of peritrochanteric disorders. RESULTS: Conservative treatment still has a place and includes activity modification, NSAIDs, analgesics, physiotherapy, home training, local corticosteroid injection (CSI) and shock wave therapy (SWT). These non-surgical alternatives have demonstrated good clinical results with low rate of complications. CONCLUSION: Most patients tend to resolve GTPS or lateral hip pain with non-surgical management in the mid-term but when everything failed, surgical options should be evaluated. The next frontier that will be a game changer is to determine an individualized treatment plan based on the exact pathology. LEVEL OF EVIDENCE: V.

Musculoskeletal injuries among elite artistic and rhythmic Greek gymnasts: A ten-year study of 156 elite athletes.

Data on elite gymnast injuries outside North America is sparse. We report the injuries recorded over a period of 10 years in 156 Greek elite male and female gymnasts. A total of 2390 injuries were reported for a rate of 1,5 new injuries per year per athlete. Most commonly affected areas were the hip (18.5%), the ankle (16.5%), the lumbar spine (16%) and the foot (16%). The most frequent diagnosis was tendinitis (32%), followed by low back pain (20%), and sprains (12%). Fifteen athletes (9%) sustained serious injuries that required surgery. Rhythmic gymnasts had significantly more overuse type injuries compared to artistic gymnasts (p = 0.049). Gymnastics is a sport with a high incidence of musculoskeletal pathology that needs proper documentation in order to establish preventive measures.

The role of cell therapies and hip arthroscopy in the management of osteonecrosis: an update.

The exact pathophysiology of osteonecrosis of the femoral head (ONFH) is still unknown. There is evidence to suggest that in ON there is decreased population and altered function of the mesenchymal stem cells (MSCs) of the femoral head. This could influence both the actual occurrence of ON itself and the repair process that follows. Hence, in such an environment it only is rational to consider the use of cell-based treatments to potentially regenerate lost or damaged bone. The aim of this review is to provide an up-to-date, evidence-based information in the use of cell therapies in the treatment of nontraumatic ONFH and the use of hip arthroscopy in the field.

Neglected lesser tuberosity avulsion in an adolescent elite gymnast.

We report the case of a 16-year-old elite gymnast who presented with recurring pain in the left shoulder after training. The athlete recalled an injury to the shoulder 2 years ago. Clinically a localized tenderness to the anterior shoulder and loss of strength and range of motion was noted. Imaging investigation suggested a neglected lesser tuberosity avulsion. The athlete was treated with open excision of the deformed tuberosity and direct repair of the subscapularis to the humeral head. Following a careful postoperative rehabilitation protocol the athlete was able to return to unrestricted gymnastics after 6 months. After surgery the athlete followed a intense rehabilitation program that allowed him to return to sports at 6 months. At 5-years follow-up, the athlete was asymptomatic and competing at an international level. Avulsion fractures of the lesser tuberosity are extremely rare injuries with significant shoulder disability if left untreated. Anatomic repair can yield excellent results, even in neglected cases.

Clinical outcome of arthroscopic suture fixation for tibial eminence fractures in adults.

PURPOSE: The purpose of this study was to evaluate the clinical outcome of arthroscopic suture fixation for tibial eminence fractures in adults. METHODS: Twelve patients with a mean age of 29.9 years (range, 18 to 45 years) were prospectively followed up after arthroscopic suture fixation for tibial eminence fractures. Along with clinical examination, Lysholm, Tegner, and International Knee Documentation Committee (IKDC) rating scales were used to evaluate the patients. Anteroposterior knee laxity was measured with a Rolimeter (Aircast, Vista, CA), and range of motion was measured with a goniometer. RESULTS: Patients were followed up for a mean of 50 months (range, 25 to 69 months). There were no detectable signs or symptoms of instability postoperatively. The mean preinjury Tegner score was 6.1 (range, 3 to 9), and at follow-up, the mean Tegner score was 5.8 (range, 3 to 9). No Lysholm or IKDC scores were obtained and no range-of-motion measurements were performed preoperatively because all injuries were acute. The mean Lysholm score was 98 (range, 94 to 100), and the mean IKDC score was 94.7 (range, 89.1 to 100). Anterior translation of the tibia, measured with the Rolimeter, was 0.58 mm on average (range, 0 to 3 mm) compared with the healthy side. Postoperatively, the mean extension deficit was 1° (range, 0° to 5°) and the mean flexion deficit was 2.7° (range, 0° to 10°) compared with the unaffected side. Overall, knees were graded as normal or nearly normal in 11 patients and abnormal in 1. CONCLUSIONS: Tibial eminence fractures in adults can be effectively treated with arthroscopic suture fixation. LEVEL OF EVIDENCE: Level IV, therapeutic case series.

A rare case of malignant triton tumor with pluridirectional differentiation.

An enlarging soft tissue mass was resected from the leg of a young man with neurofibromatosis type 1. Rhabdomyosarcomatous elements admixed with islands of osteoid and chondroid matrix was seen on microscopy. Based on immunohistochemistry, a malignant triton tumor, an uncommon subtype of peripheral nerve sheath tumor with rhabdomyosarcomatous elements, was diagnosed. The important feature of this neoplasm was that it showed pluridirectional differentiation to osteosarcoma and chondrosarcoma. This pathologic finding is rare and seen in only a few cases of all malignant triton tumors.

The complexity of seat belt injuries including spinal injury in the pediatric population: a case report of a 6-year-old boy and the literature review.

We present, along with a literature review, the case report of a 6-year-old boy, involved in a high-speed motor vehicle accident, who sustained a seat belt injury of the lumbar spine. We discuss the clinical presentation of thoracolumbar fractures in children, the sensitivity of clinical examination and radiographic evaluation and the associated abdominal injuries that are commonly present with seat belt spinal injuries. Computerized tomography is limited in the detection of soft tissue spinal fractures because these fractures occur in the plain of the section. Plain lateral x-rays of the lumbar spine and computerized tomographic three-dimensional reconstruction images can be helpful but they cannot evaluate the extent of the soft tissue injury. The magnetic resonance imaging scan is the best diagnostic tool to provide the diagnosis.

Elongation of the femoral neck in Perthes disease.

We present the long-term clinical and radiological results of a series of 168 young patients with unilateral Perthes disease who were treated in our department between 1989 and 1997, using a combined osteotomy in the longitudinal and horizontal axis of the proximal femur and elongation of the femoral neck. Surgical treatment was undertaken for any group II (Catterall's classification) patient, with the presence of two or more radiographic signs of the "head at risk" and the clinical sign of flexion with abduction, as well as for all cases classified by Catterall as groups III and IV. The surgical procedure we describe provided 147 radiologically and clinically normal hips in the short and long-term. However, in the long-term, 21 out of 168 patients presented with residual deformities such as shallow acetabulum, thickening of the acetabular floor, coxa magna, thicker and slightly shorter femoral neck. Thus for the vast majority of patients, the operation we describe here provided leg length equalisation and restored the working length of the abductors by maintaining the tip of the greater trochanter at the same level as on the unaffected side.

Outcome of physeal and epiphyseal injuries of the distal tibia with intra-articular involvement.

The authors reviewed 83 physeal and epiphyseal injuries of the distal tibia with intra-articular involvement. The children, aged 11 to 14 years, were treated in the authors' department during 1987 to 1999. Treatment was nonoperative for 72.25% (60/83) and surgical for 27.75% (23/83) according to specific indications. This gives the basis for a classification of these injuries. The main purpose of the study was to investigate the long-term results of these injuries according to a radiologic classification. The parameters considered were the patient's age, the mechanism of injury, and the possibility of growth deformities or functional disorders. They were studied relative to the long-term results, with a follow-up of 2 to 13 years. Regardless of treatment, varus deformity, ranging from 10 to 15 degrees in relation to the normal opposite leg, occurred in four cases. In only one case was there painful limitation of ankle joint movement; in two other children an overgrowth of the medial malleolus was detected, with no functional impairment.

Surgical treatment of developmental dysplasia of the hip in the periadolescent period.

The surgical management of patients with neglected developmental dysplasia of the hip (DDH) after the age of 6 years has been the subject of controversy. We present 11 cases (16 hips) of neglected DDH that were treated operatively by means of open reduction and derotational subtrochanteric osteotomy. Patient age ranged between 10 and 17 years (mean, 12 years). Follow-up ranged from 5 to 13 years (mean, 8.7 years). The results have been satisfactory both clinically (evaluated using the modified Harris hip score) and radiographically (evaluated using Severin's classification). Our data suggest that neglected DDH cases, not only during early childhood, but also in the periadolescent period, should be considered for surgical treatment.

A novel surgical option for the operative treatment of clubfoot.

Clubfoot (talipes equinovarus) is a condition well known since the time of Hippocrates. Numerous conservative treatments have been introduced for this condition; few are still in favour. Conservative treatment was used in our department up to the third month of age. The indication for surgery was failure to correct or maintain the correction after conservative treatment. We report on 134 children (206 feet) who had operative treatment for clubfoot in our department during the period 1990-1996, using a novel surgical technique based on extensive posteromedial release combined with the lateral spread of the "extensor forces" of the foot. This new technique has produced excellent results.

Talus fracture associated with a fracture dislocation of the distal tibia in an immature skeleton.

A 12-year-old boy with a severe injury of his right ankle was treated in the accident unit. The local condition was an extensive open wound with parts of the fractured bones prominent. Radiographs showed a severely displaced fracture of the body of the talus associated with a Salter-Harris IV injury of the distal tibia and subluxation of the ankle. After proper debridement the fractured bones were reduced and fixed. Eleven years later both fractures are completely healed without any sign of avascular necrosis, the patient has full painless ankle movement and he can perform his demanding occupation without any problem.

Histological and biological changes in the epiphyseal plate during fracture healing.

The alterations that the epiphyseal plate undergoes during fracture healing are well documented microscopically, yet there are no reports in the literature which discuss the cellular and molecular changes that accompany this process. We studied fracture healing in 49 Wistar rats (5 weeks old) in which we inflicted a fracture to the distal third of the femur of the right hind leg (experimental side). The rats were killed 2 weeks later, and we dissected both hind legs from the hip joint to the knee joint, detaching all the surrounding soft tissues. We manually detached the distal epiphyses and the epiphyseal plates from both femurs. A piece of the epiphyseal plate was removed from the epiphyseal side of the femurs. In 25 animals, and we analyzed the DNA content. In 8 animals, the specimen was studied under an electron microscope, and in the remaining 16 animals, the control and experimental sides were studied histologically. We found that healing was accompanied by an increase in DNA content, by a change in cellular activity, and by greatly accelerated apoptosis.
