Ulnopalmar dislocation of the fifth carpometacarpal joint. A rare injury

Volar dislocation of the carpometacarpal joint of the little finger is an uncommon injury. It is subdivided in ulnopalmar and radiopalmar dislocations. The injury can easily be missed on standard x-rays. Closed reduction and K-wire fixation has commonly been used in the treatment, although closed reduction and casting has been reported. Only 10 cases of an ulnopalmar dislocation were published previously. We report a case of a simultaneous dislocation of the 4th metacarpophalangeal joint and an ulnopalmar dislocation of the 5th carpometacarpal joint. The combination of these injuries has not been reported yet. We review the available literature and discuss the methods of treatment.     

Simultaneous Dislocation of the Metacarpophalangeal and Interphalangeal Joints of the Thumb

Combined dislocation of the metacarpophalangeal and uncommon. We know of only four previously reported cases. We report a new case characterised by dorsal dislocation of both joints. Because of entrapment of the volar plate, open reduction at the interphalangeal joint was necessary. The metacarpophalangeal dislocation was treated by closed reduction. After three weeks of immobilisation, physiotherapy resulted in a satisfactory outcome. Even if the diagnosis of dislocation of the interphalangeal joint is obvious it would be easy to overlook a simultaneous dislocation of the metacarpophalangeal joint with serious consequences. Whole hand examination remains an essential rule. interphalangeal joints of the thumb is

Complete volar metacarpophalangeal joint dislocation of a finger

A complete volar dislocation of the metacarpophalangeal joint of a ring finger occurred in a 31-year-old man and was successfully treated by a closed reduction. We found only six cases of volar metacarpophalangeal joint dislocation reported in the literature all of which needed open reduction.     

Complex volar dislocation of the distal radioulnar joint in a Galleazi variant associated with interposition of the ulnar neurovascular bundle

Galleazi type fracture dislocations are sometimes associated with complex dorsal dislocation of the distal radioulnar joint due to interposition of the extensor carpi ulnaris tendon. We present the first reported case of complex volar distal radioulnar joint dislocation in a Galleazi variant associated with interposition of the ulnar neurovascular bundle.     

Complex dorsal metacarpophalangeal joint dislocation caused by interosseous tendon entrapment: case report

We report a patient with open complex, dorsal metacarpophalangeal joint dislocation of the index finger with interposition of the first dorsal interosseous tendon and the transverse ligament of the palmar aponeurosis. To our knowledge, entrapment of the first dorsal interosseous tendon has not been reported to be the cause of irreducible dislocation of the metacarpophalangeal joint.     

Rare double fracture-dislocation of the thumb： a case report and review of the literature

Simultaneous fracture/dislocation of the thumb carpometacarpal (CMC)joint and dislocation of the metacarpophalangeal (MCP)joint is considered as a rare injury pattern.We report an unusual case of dorsa...     

Delayed post-traumatic midcarpal dislocation

We report a case of delayed post-traumatic volar midcarpal dislocation in a 39 year-old woman. The dislocation was a gradual process starting from the time of injury. Initial X-rays showed a normal midcarpal joint. By 6 weeks, lunocapitate subluxation was apparent radiologically and by the 18 week X-ray, midcarpal dislocation had occurred. This type of wrist injury has not been previously reported. Because of advanced degenerative changes in the lunocapitate joint, a partial wrist fusion was performed with a successful outcome.     

Dorsal Dislocation of the Distal Interphalangeal Joint and Volar Dislocation of the Metacarpophalangeal Joint in the Same Finger: A Case Report

Double dislocations of the finger interphalangeal and/or metacarpophalangeal joints are a rare entity. Sixty-four cases of distal and proximal interphalangeal joint double dislocations have been previously reported. Five cases of metacarpophalangeal and interphalangeal double dislocations of the thumb have also been reported. Only one case has been reported in the English literature regarding simultaneous dislocations of the distal interphalangeal and metacarpophalangeal joints in the nonthumb digit. The directions of the dislocation were the same; both were dorsal. We report, to our knowledge, the first ever case of a double dislocation a non-thumb digit in opposing directions—volar at the metacarpophalangeal joint and dorsal at the distal interphalangeal joint.     

Bilateral sacroiliac joint dislocation (anterior and posterior) with triradiate cartilage injury: a case report

Pediatric sacroiliac joint injuries are uncommon. Significant pelvis ring disruptions in children are rare, and their management is complicated by patient size, differences in bony architecture, and future growth and remodeling potential. We present a rare case of anterior sacroiliac joint dislocation associated with triradiate cartilage injury with a posterior sacroiliac dislocation on the contralateral side. This appears to be the first such case reported in the literature.     

Dorsal dislocation of the fourth and fifth carpometacarpal joints and simultaneous dislocation of the metacarpophalangeal joint of the small finger: a case report

A patient with dorsal dislocation of the fourth and fifth carpometacarpal (CMC) joints and dislocation of the metacarpophalangeal (MP) joint of the small finger was managed successfully by open reduction and transarticular fixation of the CMC joint dislocation and closed reduction of the MP joint dislocation. This rare combination of injuries has not been reported previously.     

An Unusual Variety of Simultaneous Fracture Dislocation Pattern: Medial Swivel Dislocation of Talonavicular Joint with Displaced Fractures of the Fourth and Fifth Metatarsals

In published studies, a very rare, special type of Chopart dislocation termed a swivel dislocation has been reported. This injury is characterized by dislocation of the talonavicular joint, but the calcaneocuboid joint remains intact. The foot creates a typical rotational movement without inversion or eversion. The axis of rotation is the interosseous talocalcaneal ligament, which remains intact. We report the case of an 18-year-old male who had experienced a medial swivel dislocation of the talonavicular joint associated with displaced fractures of the fourth and fifth metatarsals. The occurrence, features, and method of treatment of this rare injury are presented.     

Superior sternoclavicular joint dislocation presented with shoulder motion limitation: A case report and literature review

Introduction and importanceSternoclavicular joint dislocation accounts for 1 percent of the human joint dislocations. Sternoclavicular joint dislocation most commonly occurs in anterior or posterior dislocation. To the best of the authors knowledge, only six cases of superior sternoclavicular joint dislocation are reported in the literature. The injury is commonly missed.Case presentationWe present a 28-year-old athlete with upper chest pain and right shoulder range of motion limitation. On imaging, it was revealed that he had a superior sternoclavicular dislocation. He was managed with arm sling, analgesics and physiotherapy. After 3 months, he was asymptomatic and returned to his sport activity successfully.Clinical discussionWe searched the published related studies and summarized the signs and symptoms of patients presented with sternoclavicular dislocation. Chest pain is one of the most common symptom while sternoclavicular tenderness and restriction of shoulder movement are among the most common signs of sternoclavicular dislocations. Conservative, close reduction, and open reduction and internal fixation with fiber wire have been applied for cases with superior sternoclavicular dislocation with acceptable results.ConclusionA high index of suspicion is needed in order not to miss sternoclavicular dislocation. In cases with no evidence of mediastinal structure compression it may be managed conservatively successfully. However, some degree of cosmetic deformity may remain at the sternoclavicular joint in those treated with conservative therapy.     

Die dorsale karpometakarpale Luxation des 5. Strahls

Dorsal dislocation of the fifth carpometacarpal joint after injury is rare. Only five cases are reported in the literature. We report on two cases of dorsal dislocation of the fifth carpometacarpal joint after injury and we give a review of related literature. There are two interesting aspects concerning diagnostic and therapy of dorsal dislocation of the fifth carpometacarpal joint. Anterior-posterior and lateral radiographs do not always provide adequate visualisation of this joint so a dislocation may be misdiagnosed. A radiograph taken with the forearm pronated 45 degrees from the routine anterior-posterior position better shows the dislocation. The adequate therapy consists in closed reduction, Kirschner wire fixation and cast immobilisation. A reduction without following Kirschner wire fixation - even in those dislocations that were found to be stable after closed reduction - is not recommended because of the risk of persisting pain after heavy manual work. In our two cases an instability of the fifth carpometacarpal joint existed after closed reduction. After Kirschner wire fixation and cast immobilisation for 6 weeks both patients showed 3 months after operative therapy a full range of movement and a powerful grip without any pain in the fifth carpometacarpal joint.     

Complex volar distal radioulnar joint dislocation occurring in a Galeazzi fracture

The Galeazzi fracture-dislocation of the forearm consists of a transverse or short oblique fracture of the radius at the junction of the middle and distal thirds with an associated subluxation or dislocation of the distal radioulnar joint. Anatomic reduction with rigid internal fixation of the radius typically produces anatomic reduction of the distal radioulnar joint and is the favored treatment. At least three cases of a mechanically blocked distal radioulnar joint requiring open reduction through a separate exposure have been reported. In all three cases there was dorsal displacement of the ulna. We report a case of an irreducible volar dislocation of the distal radioulnar joint following open anatomic reduction of the radius.     

Isolated palmar dislocation of the fifth carpometacarpal joint diagnosed by stress X-rays

Isolated palmar ulnar dislocation of the fifth carpometacarpal (CMC) joint is a rare injury which often yields only subtle radiographic findings that may be easily overlooked, especially when there is no associated fracture. We reported a case of an isolated palmar dislocation of the fifth CMC joint, diagnosed correctly by means of simple stress X-rays (traction and axial compression stress views). This method proved to be useful and needs no special equipment. Received: 7 January 1999     

Unusual combined fracture dislocation of the wrist and metacarpophalangeal joints: a case report and review of the literature

Volar perilunate fracture dislocation is an extremely rare carpal injury, but associated with metacarpophalangeal joint dislocation of both the ipsilateral index and middle finger has never been reported. We report one case of a 28-year-old man following a high-energy trauma.After performing closed reduction of the metacarpophalangeal joint injury, open reduction of the wrist injury through volar approach was done, and a K-wire fixation was used to stabilize the scaphoid fracture and lunotriquetral joint. After a 16 months' follow-up period, the wrist regained a full range of motion without symptoms, and the fractured bone was strengthened in a good position.     

Lumbar plexus injury in an anterior fracture dislocation of sacroiliac joint: a case report and review of literature

Displaced unstable pelvic fractures are commonly associated with disruption of the osteoarticular junction of the sacroiliac joint. Posterior sacroiliac dislocation are commonly reported but there are only few reports the anterior type of sacroiliac dislocation where the iliac bone fractures and displaces anterior to sacrum, often in combination with fractures of pubic rami and symphyseal injuries. We present a case of an anterior type of sacroiliac fracture dislocation which was associated with a lumbar plexus injury involving both motor and sensory components. Preoperative neurological assessment was done by MRI scan. The tented nerve roots were explored and decompressed surgically, and sacroiliac fixation was done after reduction in the fracture and joint.     

A rare case of closed isolated dislocation of the third metacarpophalangeal joint of the hand

Metacarpophalangeal joint [MCP] dislocations of the index, little and thumb are common; that of the middle finger is very rare. In all the literature consulted only five cases of isolated closed dorsal dislocation of the MCP joint of the middle finger have been reported. Hyperextension of MCP joint is the mechanism of injury. We are herewith reporting a case of isolated MCP dislocation of the middle finger.One of our medical students while driving a motorcycle fell down on the road and sustained lacerated wound over the hypothenar area of the left hand. There was prominence of the head of the third metacarpal on the volar aspect and the base of the proximal phalanx was prominent dorsally. MCP dislocation of the middle finger was our clinical diagnosis which was confirmed by the radiograph. The patient had reported within 60 min of the accident.There was no tendon injury. Wound debridement was done, wound was extended to the back of the middle finger. The volar plate which was interposed between the head of the metacarpal and the base of the proximal phalanx was repositioned and the dislocation was reduced. Reduction was stable and the patient was reviewed after 14 months. The function of the hand is satisfactory.The case is presented for its unique presentation. This is the sixth case of isolated dislocation of the MCP joint of the middle finger.     

Palmar oblique ligament reconstruction for carpometacarpal joint dislocation in an 11-year-old: a case report.

Traumatic dislocation of the thumb carpometacarpal joint has been rarely reported in children. An 11-year-old boy presented with a traumatic dislocation of the trapeziometacarpal joint. He was successfully treated surgically with ligament reconstruction as previously described.
