Shwachman-Diamond syndrome.

Shwachman-Diamond syndrome (SDS) is a rare autosomal recessive disorder with exocrine pancreatic insufficiency, bone marrow failure and skeletal abnormalities. Patients frequently present failure to thrive, susceptibility to infections and short stature. A persistent or intermittent neutropenia occurs in 88-100% of patients.

Over-the-top double-bundle revision ACL reconstruction.

Revision ACL presents many technical issues that are not seen in the primary ACL reconstruction. A variety of surgical techniques for revising ACL reconstruction have been described in the literature to address these concerns. The purpose of this article is to present a novel technique consisting in a non-anatomic double-bundle ACL revision reconstruction, using a fresh-frozen Achilles tendon allograft with soft tissue fixation.

Surgical treatment of displaced acetabular fractures.

Introduction: Acetabular fractures are severe injuries, generally caused by high-energy trauma, most frequently from traffic accidents or falls from heights. Fractures of the extremities, head injuries, chest, abdomen and pelvic ring injuries are most commonly associated injuries.

Objective: The purpose of this study was to evaluate the results of open reduction and internal fixation of acetabular fractures.

Advance in the treatment of aneurysmal bone cyst of the sacrum.

Objective: The objective of this study was the review of 11 patients with two different treatment methods used historically for aneurysmal bone cyst in the sacrum. The outcome of both procedures is reported. In addition, the treatment technique of CT-guided percutaneous injections of demineralized bone matrix mixed with bone marrow concentrate is described.

Arthroscopic lateral collagen meniscus implant in a professional soccer player.

A case of an arthroscopically implanted lateral Collagen Meniscus Implant in a 24-year-old professional soccer player is reported. This meniscal scaffold was able to improve knee function and reduce pain in this symptomatic meniscectomized young athlete at 36-month follow-up. This is the first case of an arthroscopic lateral collagen meniscal scaffold implanted in a high-level soccer player described in literature.

Ultrasonographic evaluation of the shoulder in asymptomatic overhead athletes.

This study aimed to evaluate the efficiency of ultrasonography (US) in the examination of soft tissue anatomical structures of the shoulder in overhead athletes. The study evaluated the shoulders of overhead elite premier league athletes involved in basketball, handball, volleyball, body building, and water polo. US examination of both shoulders was performed prospectively in 45 asymptomatic overhead athletes and 43 asymptomatic volunteers matched for age.

Single-bundle patellar tendon versus non-anatomical double-bundle hamstrings ACL reconstruction: a prospective randomized study at 8-year minimum follow-up.

Purpose: The purpose of this study was to compare subjective, objective and radiographic outcome of the lateralized single-bundle bone-patellar tendon-bone autograft with a non-anatomical double-bundle hamstring tendons autograft anterior cruciate ligament (ACL) reconstruction technique at long-term follow-up.

Methods: Seventy-nine non-consecutive randomized patients (42 men; 37 women) with unilateral ACL insufficiency were prospectively evaluated, before and after ACL reconstruction by means of the above-mentioned techniques, with a minimum follow-up of 8 years (range 8-10 years; mean 8.6 years).

Delayed surgical treatment of supracondylar humerus fractures in children using a medial approach.

Purpose: The appropriate management of supracondylar humerus fractures in children is frequently delayed due to various factors, and there is still no agreement on the treatment of choice. The purpose of this study was to evaluate the effects of delayed treatment of displaced supracondylar humerus fractures on the treatment results and complication rate.

Methods: A total of 31 children with supracondylar humerus fractures who had not received adequate treatment for their displaced fractures were included in this study.

Correlation between posteromedial or posterolateral displacement and cubitus varus deformity in supracondylar humerus fractures in children.

Purpose: Cubitus varus deformity is one of the most common complications after displaced supracondylar humeral fractures in children. The purpose of this study was to evaluate the relationship between the fracture displacement and cubitus varus deformity in displaced supracondylar humerus fractures.

Methods: Seventeen patients (11 males/6 females; mean age 7 years) with cubitus varus deformities occurring after Gartland type III posteromedial or posterolateral displaced supracondylar humerus fractures were evaluated with clinical and serial radiographic examinations.

The reaction of the pelvis to the implantation of the acetabular component of the hip endoprosthesis--initial tests with the use of computerized tomography.

Among the population over the age of 65 years joint diseases constitute more than 50% of chronic diseases and most often apply to the hip. Endoprosthetics is one of the methods for treating this condition and is considered one of the best--clinically and economically--interventions of the modern medicine. However, it is not free of complications among which the loosening of the endoprosthesis is commonest.

Anatomy of the deep fascia of the upper limb. Second part: study of innervation.

Analysis of specimens taken from different areas of the deep fascia in 20 upper limbs was made in order to establish which kind of nerve fibres and endings are present in the deep muscular fascia. The flexor retinaculum and the lacertus fibrosus were also evaluated because they are anatomically hardly separable from the deep muscular fascia, although they have different functions. In particular, specimens were taken at the level of: (a) the expansion of pectoralis major onto the bicipital fascia, (b) the middle third of the brachial fascia, (c) the lacertus fibrosus, (d) the middle third of the antebrachial fascia, (e) the flexor retinaculum.

Juvenile dermatomyositis with bilateral progressive knee flexion contracture.

Juvenile dermatomyositis is a multisystem, inflammatory vasculopathy that primarily affects muscles and skin. Calcinosis is one of the most debilitating complications affecting patients with juvenile dermatomyositis. Calcifications resulting from calcinosis frequently are located on the elbows, knees, and other joints and can cause considerable disability with severe pain, joint contractures, skin ulcers, and muscle atrophy.

External fixation of open subtalar dislocation.

Subtalar dislocation is a rare and severe injury, caused by high-energy trauma such as fall from a height or traffic accident. Infection and avascular necrosis are not rare sequelae of open subtalar dislocation, and the outcome may be poor. External fixation allows complete wound care, and moderate distraction of the ankle joint should unload the talus, which may reduce the risk of avascular necrosis.

Compression neuropathy of the peroneal nerve caused by a ganglion.

Peroneal nerve injury usually results from fracture of the fibula neck or direct pressure from an ill-fitting plaster cast. Clinically, these patients present with "drop foot." Compression neuropathy caused by a ganglion is rarely encountered.

Blood supply of the articular disc of the antebrachiocarpal joint in dogs.

The normal vascular anatomy of the articular disc of 48 antebrachiocarpal joints was studied in 24 dogs (12 puppies and 12 adult animals) using an India ink vascular injection technique. It was found that the articular disc receives its blood supply mainly from the palmar and dorsal branches of the palmar interosseous artery. Branches of these 2 arteries arborise and give direct peridiscal vessels to the dorsal, proximal and palmar sides of the articular disc.

The computed tomographic evaluation of patellofemoral joint in patellar fractures treated with open reduction and internal fixation.

In this study, we examined 97 patella fractures in which open reduction and internal fixation had been performed at the 1st Orthopaedics and Trauma Clinic of Social Security Ankara Hospital between January 1983 and December 1988. After 24 to 96 months, on an average of 48.4 months follow-up period, the cases were evaluated clinically for knee function complaints and by CT and roentgenography for patellofemoral articulation.

Therapeutic synergism between hyaluronic acid and dexamethasone in the intra-articular treatment of osteoarthritis of the knee: a preliminary open study.

In vitro studies on the effects of dexamethasone on human synovial cells have shown that with high concentrations of the steroid in the culture medium cellular activity was completely blocked whereas with low concentrations (10(-6)M), cellular density decreased but there was an increase in the synthesis of RNA, DNA, protein and hyaluronic acid. These data, coupled with clinical experience of using intra-articular hyaluronic acid to treat patients with osteoarthritis of the knee, prompted the investigators to carry out an open, randomized study of the use of very small doses of dexamethasone in association with hyaluronic acid in 40 osteoarthritic patients. Twenty patients received a weekly intra-articular injection of 20 mg sodium hyaluronate in 2 ml phosphate buffer for 5 weeks; the other 20 patients followed a similar treatment regimen, the only difference being the addition of 0.

The treatment of tibial fractures by elastic nailing and functional plaster cast.

From June 1984 to December 1985, 32 fractures of the tibia were treated by elastic nailing by the Ender method with functional plaster casts according to the Sarmiento method. They represented 28% of all tibial fractures treated during the same period by the traditional conservative method or by external fixators. Elastic nailing was reserved for unstable fractures produced by high velocity trauma.
