复位内固定联合腕骨间韧带修补治疗急性经舟月骨或月骨周围脱位

Objective To evaluate the results of Open reducdon and internal fixation combined with repairing of the intercarpal ligaments using suture anchors for the treatment of perilunate fracture dislocations or perilunate dislocations. Methods From February 2004 to August 2006,12 cases of perilunate fracture dislocations or perilunate dislocations were treated operatively,in which 8 cases were transscaphoid fracture dislocations and 4 cases were perilunate dislocations.All the fractures were fixed with AO 3.0 mm cannulated screws or 3.0 mm Bold screws,with the scapholunate or lunotriquertral ligaments sutured by Mitek mini suture anchors. Results All cases were followed up for a mean period of 37 months(from 33 to 48 months).All the scaphoid healed primarily,the height of the carpal was maintained well with a mean scapho-lunate angle of 50°(35°to 65°),mean radio-lunate angle of 5°(-10°to 15°),the mean index of carpal height was 0.51(0.50 to 0.53),the ROM of the wrist iS about 92.5°,The grip strength was 76.7% of the contralateral side.The modified Nayo wrist score revealed 1 excellent,4 good,4 fair and 3 poor results.The average score was 72(50to 95). Collclusion The wrist function can be obtained satisfactorily by early open reduction and internal fixation for perilunate fracture disloeations or perilunate dislocations.Carpal instability or carpal collapse can be avoided by Intercarpal fixation and ligaments rear in short term.

Objective To discuss the effect of transarticular screws combined with lateral mass screws or pedicle screws through posterior approach in the lower cervical spine. Methods From February 2003 to October 2007, 22 patients were treated using transarticular screws internal fixation combined with lateral mass screws or pedicle screws in Axis plating system and Vertex system. There were cervical fracture and dislocation in 13 patients, ossification of the posterior longitudinal ligament in 4, cervical canal stenosis associated with dentoid process fracture in 1, and cervical disc herniation associated with cervical stenosis in 4 patients. Lamina or facet bone grafting were used to achieve a long-term stability, with decompression and anterior approach or not. The starting point for screw insertion was located 1 mm medial to the midpoint of the lateral mass and the direction of the screw was 40° caudally in the sagittal plane and 20° laterally in the axial plane. Results All screws insertion was successful. A total of 45 transarticular screws were inserted, with 2 in C4,5, 39 in C5,6 and 4 in C6,7. A total of 12 lateral mass screws were inserted, with 6 in C3 and 6 in C4. A total of 41 pedicle screws were inserted, with 4 in C2, 2 in C3 and 6 in C4, 21 in C7 and 8 in T1. There was no complication related to screw insertion, such as injury to the vertebral artery, nerve roots or spine cord. The follow-up period ranged from 10 months to 3 years and 8 months (mean 17 months). All cases got bone fusion. Only one instance of screw partial backout was identified, but fusion was achieved in all pa-tients. In the follow-up period, only one instance of screw partial backout was identified, but fusion was achieved in all patients. Conclusion The combined use of transarticular screws and lateral mass screws or pedicle screws fixation in the lower cervical spine can enlarge the advantages of strong stability,relatively simple, and reduce operating risk when performed appropriately.

Management of trans-scaphoid perilunate dislocations

A retrospective review of 28 patients with 29 trans-scaphoid perilunate dislocations who underwent open reduction and Herbert screw fixation is presented. The majority of the patients had satisfactory results at 24 months of follow-up. A significantly better range of wrist motion was obtained in postoperative patients treated with cast immobilization for 4 weeks compared with those treated for longer than 5 weeks. The scaphoid fractures united well, with proper alignment of the carpal bones, regardless of the length of cast immobilization. We recommend open reduction, internal scaphoid fixation using a Herbert screw, carpal ligament repair and early cast removal in the management of trans-scaphoid perilunate dislocations.     

Treatment of chronic perilunate dislocations

Fifteen patients with 16 perilunate dislocations that had been untreated for a minimum of 6 weeks after the injury were evaluated after subsequent treatment at a mean of 6.4 years. The median time from injury to definitive treatment was 17 weeks. Ten wrists had completely ligamentous injuries and six had fracture-dislocations. Treatment consisted of open reduction and internal fixation in six patients, isolated carpal bone excision in four, wrist arthrodesis in two, proximal row carpectomy in two, and bilateral carpal tunnel release in one. In this series the results of excision of the lunate or scaphoid alone were uniformly poor. One of the two patients who had a proximal row carpectomy required secondary radial styloidectomy, and a pseudarthrosis developed in one of the two patients who had a wrist arthrodesis. All six patients treated by open reduction and internal fixation had satisfactory outcomes and none required additional surgery.     

Use of external fixation for perilunate dislocations and fracture dislocations

The purpose of this study was to review clinical and radiographic outcomes of perilunate dislocations and fracture dislocations treated with external fixation and K-wire fixation. Twenty patients (18 males and two females) with a mean age of 38 years (range 18–59) who had an acute dorsal perilunate dislocation or fracture dislocation were treated with the use of wrist external fixator and K-wires. The injuries included 12 perilunate dislocations, seven trans-scaphoid perilunate fracture dislocations, and one trans-styloid perilunate fracture dislocation. The median time from trauma to operation was 8 h (2–12 h). Indirect reduction via ligamentotaxis was achieved in all perilunate dislocation, and provisional K-wire fixation was added. In five of seven trans-scaphoid perilunate fracture dislocations, indirect reduction was achieved; whereas in the other two as well as in the case of trans-styloid perilunate fracture dislocation, open reduction was required. External fixator was supplemented with K-wires for stabilization of the fractures and the intercarpal intervals. The interosseous and capsular ligaments were not repaired, even after open reduction of fracture dislocations. The mean follow-up was 39 months (range 18–68 months). Range of motion and grip strength were measured. Cooney’s scoring system was used for the assessment of clinical function. Radiographic evaluation included time to scaphoid union, measurement of radiographic parameters (scapholunate gap, scapholunate angle, lunotriquetral gap, and carpal height ratio) and any development of arthritis. The flexion-extension motion arc and grip strength of the injured wrist averaged 80 and 88%, respectively, of the corresponding values for the contralateral wrists. According to Cooney’s clinical scoring system, overall functional outcomes were rated as excellent in four patients, good in eight, fair in six, and poor in two. Eighteen patients returned to their former occupations. Two patients with a trans-scaphoid perilunate injury developed nonunion of the scaphoid; one of them required scaphoid excision and midcarpal fusion. Two patients had radiographic evidence of arthritis. The use of external fixation and provisional K-wire fixation for the treatment of acute perilunate dislocations is associated with satisfactory midterm functional and radiographic outcomes. This minimally invasive treatment option is simple, reliable, and minimally invasive method that provides proper restoration and stable fixation of carpal alignment.     

Late treatment of unreduced perilunate dislocations.

Twenty-eight patients with perilunate dislocations that had been untreated for a minimum of 6 weeks after injury were assessed at a mean of 6.8 years after subsequent treatment. Treatment consisted of open reduction with or without internal fixation of the scaphoid in six patients, proximal row carpectomy in 16, total excision of the lunate in four, and carpal tunnel release and partial excision of the lunate in two. Open reduction yielded satisfactory results in cases of less than 2 months standing. We believe that proximal row carpectomy should be considered in the treatment of chronic perilunate dislocations in patients who are seen later than 2 months after injury, if the cartilage of the proximal pole of the capitate is well preserved. The results of lunate excision were less favourable.     

Treatment of acute lunate and perilunate dislocations

Acute lunate and perilunate dislocations are uncommon but devastating carpal injuries with a guarded prognosis. This article outlines the pathoanatomy, diagnosis, indications for treatment, technique, and expected results of open reduction and internal fixation.     

Open reduction of chronic lunate and perilunate dislocations

Four patients with chronic lunate and perilunate dislocations were treated by open reduction and internal fixation. The interval between injury and operation was 7, 8, 14 and 18 weeks, respectively. Both palmar and dorsal surgical approaches were needed to reduce the old dislocation in all cases. A case of dorsal trans-scaphoid perilunate dislocation showed concurrent partial disruption of the scapholunate ligament. Transient vascular compromise of either the lunate or the proximal scaphoid fragment was noted in three patients. Despite the delay in treatment, all patients had satisfactory outcomes.     

Proximal row carpectomy in perilunate dislocations and lunatomalacia

Proximal row carpectomy was performed in 13 wrists with old unreduced perilunate dislocations and in 4 wrists with Kienb?ck's disease. One failure was converted to wrist arthrodesis, and 2 patients were lost to follow-up. The remaining 14 patients were reexamined after 11 (3-19) years. Average ranges of wrist motion were 37 degrees of dorsiflexion, 30 degrees of palmar flexion, 5 degrees of radial deviation, and 24 degrees of ulnar deviation. Grip strength averaged two thirds of the uninvolved hand. Pain relief was achieved in 12 patients, who all returned to their previous occupations. The results according to Cooney's criteria were 1 good, 8 fair, and 5 poor.     

Proximal row carpectomy for chronic unreduced perilunate dislocations

We evaluated the results of proximal row carpectomy (PRC) for unreduced perilunate dislocation in 6 patients. The average period from the injury to the operation was 24 weeks. The modified Mayo wrist score was used for clinical evaluation. Radiological evaluation was based on the radius-capitate alignment. Pain disappeared in 4 cases; mild pain during activity persisted in 2 cases. The average flexion-extension are was 59% of the values on the unaffected side. The average grip strength was 72% of the unaffected side, and the average modified Mayo wrist score was 71 points. Three patients showed favourable radius-capitate alignment, while the other 3 patients showed poor radius-capitate alignment on the radiographs. The postoperative radius-capitate alignment was related to the preoperative position of the capitate on the lateral view. Those with poor radius-capitate alignment tended to obtain lower scores compared to those with favourable alignment.
