Synovial chondromatosis is a rare benign intraarticular metaplasia of synovium. This process may result in the production of detached particles of highly cellular cartilage in the involved joint spaces. It is most often reported in the larger joints of the body including the knee, hip, elbow, and ankle. Since Axhausen ...

The term "luxatio erecta" has been borrowed from the shoulder to identify rare traumatic hip dislocations in which there is inferior dislocation of the femoral head and inversion of the femoral shaft. A review of the literature is presented along with an additional illustrative case. The mechanism of injury, and ...

An 85-year-old man was found to have a calcified mass protruding from the joint space of the right temporomandibular joint (TMJ). Microscopically, the removed mass consisted of chondromyxoid tissue with atypical chondrocytes, resembling a cartilaginous tumor. However, the chondromyxoid tissue contained abundant deposits of rod-shaped to rhomboid crystals which proved ...

Pigmented nodular synovitis is an uncommon condition of the foot. In this case history, we report a case of pigmented nodular synovitis in the first metatarsophalangeal joint, treated by arthroscopic synovectomy. Pigmented nodular synovitis to our knowledge has not been described in the first metatarsophalangeal joint. We report successful treatment ...

A case of an unusual destructive hip osteo-arthropathy with a plain-film record of rapid joint destruction is reported. In the absence of any laboratory or pathological support for other pathology this is thought to be an uncommon example of erosive or inflammatory osteo-arthritis in a large joint.

The authors describe a case of superior dislocation of patella that was irreducible by closed methods. Extensive review of the literature revealed that this is the first case reported in which an open reduction was needed to reduce a superior dislocation of the patella to unlock the osteophytes, which were ...

In order that the factors causing poor surgical outcome might be clarified, 175 duplicated thumbs bifurcating at the metacarpophalangeal joint level were analyzed. Cases were further divided into types A-D, based upon the details of the bifurcation form; that is, based on the connection of the radial digit to the ...

Fusion of the shoulder joint after a brachial plexus injury is a well known procedure in cases of flail shoulder in combination with normal motor and sensory function in the band. However, in combination with modern orthoses to stabilize the elbow, fusion of the shoulder in cases of a totally ...

This article reports a case of digital intraarticular envenomation from a T. flavomaculatus mcgregori pit viper resulting in severe joint damage. Bites by these snakes are rare in the U.S.A. since this species is only found in collections and zoos. Intraarticular envenomations from crotalids are rare and may result in ...

Anterior subtalar dislocations are extremely rare. To our knowledge, only four cases have been reported in detail in the literature. A diagnosis of anterior subtalar dislocation should be confirmed by an anteroposterior view radiograph because lateral subtalar dislocation always includes some anterior displacement of the mid-foot. We report a case ...

Simultaneous bilateral posterior dislocation of the hip is very uncommon and most cases are caused by road accidents. Simultaneous bilateral posterior dislocation of the hip due to convulsions is extremely rare. We report the case of a man who was diagnosed late and operated on 15 weeks after the injury. ...

There are many reports about the snapping syndrome in the hip, shoulder, and ankle, but the snapping knee has rarely been reported. In general, the symptom of this disorder is relatively tolerable and seldom requires operative treatment. We experienced one case of the snapping knee, for which the pain, easy ...

Intraosseous pneumatocyst of the ilium is a rare lesion of uncertain origin. It predilects male subjects and may be associated or not with sacroiliac joint degenerative disease, intra-articular gas, sacral pneumatocyst, and communication with the articular space. To our knowledge, only 16 observations have been reported in the literature. We ...

Nine cases of acquired absence of the fibular shaft were studied to determine the growth contribution of the distal fibula; in 6 cases the absence was caused by osteomyelitis and in 3 cases by trauma. The average valgus and external rotational deformities were 15.2 degrees and 10 degrees, respectively. In ...

Rickets can manifest with a wide variety of rheumatic symptoms. In this paper, a fifteen year old female patient with hypophosphatemic rickets presenting with symptoms suggesting sacroiliitis at disease onset is reported. The sacroiliac joint involvement in this case was attributed to the subchondral bone fractures due to the secondary ...

A case of bilateral temporomandibular joint (TMJ) ankylosis in a Chinese male patient with ankylosing spondylitis is presented. A review of the literature emphasizes the rarity of this arthro-pathology in ankylosing spondylitis. The importance in the recognition of this complication by clinical examination supplemented by computed tomography is stressed.

A case study is presented to illustrate the concept of femoral component failure secondary to polyethylene wear in a 67 year old man, 13 years after he had conforming type total knee replacements. This case illustrates the theory that this observed problem may be a leading cause of failure in ...

Traumatic hip dislocation constitutes a true orthopedic emergency, is a relatively rare occurrence in the pediatric population, and may be accompanied by minimal trauma. Long-term morbidity such as avascular necrosis or osteoarthritis of the femoral head may be significant if the diagnosis is not expeditiously confirmed radiographically and prompt reduction ...

We report on a 13-month old boy with microcephalic osteodysplastic primordial dwarfism (MOPD), whose radiographic signs correspond with type II of this entity. Some of his clinical signs, such as the anomalies of the external genitalia and the urinary tract, are common to this subgroup of MOPD, but he also ...

Synovial chondromatosis is a benign monoarticular arthropathy characterized by metaplastic cartilaginous foci developed in the synovial membrane. We present a review of the literature and report on five additional cases of synovial chondromatosis of the temporomandibular joint. Radiographic examination by computed tomographic scan allowed us to identify this disease as ...

The hypotheses that carpal arcs normally break in radial and ulnar deviation and that they remain intact in the neutral position were tested. Wrist instability series of 100 asymptomatic wrists were reviewed. Three carpal arcs were drawn on posteroanterior (prone) and anteroposterior (supine) x-ray films in neutral and radial- and ...

PURPOSE: To assess the incidence and visual morbidity of lens matter dislocation during phacoemulsification and the relationship between this complication and surgical experience.

They were asked about the incidence ...

Disk displacement of the temporomandibular joint (TMJ) without reduction has been considered a fundamental pathophysiologic abnormality of the joint. In this paper there are supportive clinical and MRI evidence of a successful repetitive manipulative technique for the treatment of acute and chronic locking. In 1500 treated cases, documented on videotape, ...

Carpometacarpal dislocations of the ulnar four joints are rare injuries that are usually associated with high-energy trauma. Given the small number of cases reported, there exists some controversy regarding their optimal management. The case of a 27-year-old man who sustained a dorsal dislocation (without associated fractures) of the ulnar four ...

Reflex sympathetic dystrophy syndrome (RSDS) is a well-defined entity, caused by many clinical conditions, leading to pain, stiffness, and vasomotor changes in the affected region. In this case, a 49-year-old man presented with a history of right foot pain secondary to a fall. Plain radiographs did not reveal any fractures ...

Acetabular labral tears are well recognized in the pathology of hip disease. The patterns of such tears found in 37 patients undergoing hip arthroscopy have been analyzed. Distinct categories of labral tear were found, and may be classified in terms of etiology (traumatic, 18.9% of cases; degenerative, 48.6%; idiopathic, 27.1%; ...

The Walkabout is a new hip-knee-ankle-foot orthotic (HKAFO) system with a medial single hip joint (MSH-KAFO) invented by S. McKay in 1992. Compared with other HKAFO systems, the hip joint part is compact and removable, so it has distinguishable, real merits: ease in donning and doffing the device, compatibility with ...

In two cases of flexion contracture of knees, the vertical septum pattern of the infrapatellar plica was noted arthroscopically to be thickened, fibrotic, and to have lost its elasticity. The plicae were impinged to the intercondylar notch and trochlea at extension of the knees, blocking further extension. The pathological plicae ...

A case report of a 28-year-old man with associated dislocations of the tarsometatarsal (Lisfranc) and metatarsophalangeal joints is presented. The potential for disability after these injuries is very high when the diagnosis or treatment is delayed, the reduction is incomplete, or the dislocation recurs. Relevant aspects of diagnosis and treatment ...

A case of synovial chondromatosis in a great horned owl (Bubo virginianus) was found in June 1993. In radiographs of bilateral swelling of the scapulohumeral joint we observed numerous mineralized foci in the soft tissue. The foci were identified by light microscopy as cartilaginous metaplasia. This is the first report ...

The clinical observations on 14 cases of temporomandibular joint (TMJ) ankylosis including age and sex incidences as well as surgical management are presented in this paper. Ankylotic TMJ arthroplasty which include condylectomy with or without interpositional materials such as auricular cartilage and temporalis muscle flap to prevent reankylosis was used ...

Posterior dislocation of the sternoclavicular joint is uncommon, accounting for less than 0.1% of all dislocations. Since 1824 a little more than 100 cases have been reported, and the majority in the past 20 years. A review of published reports suggests that this injury is seen particularly in connection with ...

A case of neglected elbow dislocation having a late open reduction is presented and the literature reviewed. While the functional result is inversely related to the interval between injury and the time of operation, stability and early motion are two keys for good functional recovery. A new method of coronoid ...

A 17-year-old girl with unilateral atypical cleft foot deformity is reported. In this case the deformity was associated with deafness, mandibular retrognathia and congenital bilateral temporomandibular joint luxation. Family history of cleft foot deformity was not found. A syndactylization procedure with shortening of the big toe was done. The temporomandibular ...

McWharter first described volar carpometacarpal dislocations of the fifth digit in 1918. Since then, 14 cases have been reported in the medical literature. Berg and Murphy were first to report a case of ulnopalmar dislocation that was successfully treated with closed reduction and immobilization. Previously reported cases required internal fixation ...

Subtalar dislocations are sufficiently uncommon to be unfamiliar but require appropriate recognition and management to effect a good outcome. These dislocations benefit from urgent reduction that is essential to limiting sustained disability. Most can be reduced by closed manipulation at the time of presentation. Three cases of subtalar dislocations are ...

Herniation of the temporomandibular joint into the external auditory canal has been reported as a result of trauma, neoplasia, infection, inflammatory processes, or developmental malformations. This paper reviews the intimate relation of the temporomandibular joint to the temporal bone as well as the literature describing temporomandibular joint herniation into the ...

Heterotopic ossification has been reported to occur in less than 10% of total knee arthroplasties. When this condition has occurred, it has previously been reported either to be asymptomatic or to cause discomfort that resolves with the passage of time. This case report is the first to note persistent pain ...

A case is described of a policeman who assaulted the man he was arresting after receiving a concussive blow to the head. The defence argued he was suffering from post-traumatic automatism and after juries were unable to agree a verdict in two trials he was acquitted. Aspects of post-traumatic automatism ...

Irreducible dorsal dislocation of the interphalangeal joint of the great toe is rare. Few case reports can be found in the literature.
