Results of osteotomy, open reduction, and internal fixation for late-presenting malunited intra-articular fractures of the base of the middle phalanx.

PURPOSE: To present our results in the treatment of late-presenting impaction fractures of the base of the middle phalanx treated by osteotomy with full exposure of the articular surface to restore the normal anatomy. METHODS: Eleven patients with a malunited (impacted) fracture of the base of the middle phalanx were treated by osteotomy more than 5 weeks after the injury. All fractures had varying degrees of impaction, comminution, and dorsal subluxation. The malunited joint surface was visualized by dislocating the joint by hyperextension (shotgun approach). The restoration of the cup-shape contour of the middle phalangeal base was accomplished by osteotomy and mobilization of small osteochondral fragments. Rigid fixation was performed by cerclage wire, screws, or a combination of these. A distal radius bone graft was placed beneath disimpacted fragments in 9 of the 11 procedures. RESULTS: Ten of 11 patients were followed-up for more than than 1 year. One patient with a volar lateral impaction fracture was lost to follow-up study 4 weeks after the surgery and was excluded from the results. All patients except 1 achieved a functional range of motion of the proximal interphalangeal joint. Moderate limitations of the distal interphalangeal joint motion were common. Grip and thumb-affected finger tip pinch strengths were 95% and 90%, respectively, of the healthy side. The average pain level (as rated on a visual analog scale of 0-10) improved from a preoperative score of 9.1 to a postoperative score of 0.8. One patient was somewhat dissatisfied; all other patients were satisfied or very satisfied. All returned to their previous work at an average of 13 weeks after surgery. CONCLUSIONS: Favorable results have been achieved in this challenging scenario in the short- and middle-term in 9 of 10 patients. Previous surgery and moderate to severe wearing of the cartilage of the proximal phalanx head negatively affected the results.

Internal fixation of scaphoid non-union: a comparative study of three methods.

In this study we compared the results of three methods of fixation for scaphoid non-union. The implants used were the AO 2 mm mini-fragment screw, the Herbert screw and the Kirschner (K) wires. Between 1990 and 1999, 132 patients underwent surgery for scaphoid fractures. We used the modified Filan and Herbert classification. Patients with acute fractures and patients requiring vascularised bone grafts were excluded. Twenty-six non-unions were fixed with an AO mini-fragment screw, 58 with a Herbert screw, and nine with K-wires. Radiological union was achieved in 85% of cases using the AO screw, 77% using the Herbert screw and 55% using the K-wire fixation. Statistically there was no significant difference between the AO and Herbert screw groups in terms of rate and speed of radiological union. The mechanical strength of the implant and the compression achieved did not seem to influence the union rate and speed. The type of bone graft (iliac crest or distal radius) did not significantly affect the union rates. Finally, K-wire fixation, either as a primary method or as a salvage procedure, produced inferior results and required prolonged immobilisation in plaster.

Review of the radiology in randomised controlled trials in open reduction and internal fixation (ORIF) of displaced intraarticular calcaneal fractures.

The aim of this study was to assess the radiological evaluation of all prospective, randomised, controlled trails of displaced intraarticular calcaneal fractures. A systematic review of the literature, of which only three of 296 references were randomised and controlled, were examined in a blinded fashion. All had preoperative coronal CT for Sander's classification and used a lateral surgical approach or conservative treatment. Thordason (15 patients/11 controls) used interoperative lateral and axial X-rays. Bohler's angle increased on average from 11 to 26 degrees (P<0.001) postoperatively, but decreased (9-8 degrees ) in the conservative group. The posterior facet residual displacement was 1.1 and 4.7 mm, respectively. O'Farrell (12 patients/12 controls) showed 8 out of 12 had Bohler's and Gissane's angle partially or fully restored postoperatively, and not conservatively. Parmar (25 patients/31 controls) used preoperative lateral radiographs, but failed with CT to grade the postoperative reduction, whilst the conservative group was unaltered. There was no systematic, blinded assessment of the change in radiology by the operative intervention. Overall there was weak evidence to support ORIF. In conclusion, there are only three randomised, controlled studies involving small numbers of patients, which showed improved plain radiographic anatomical alignment, in the postoperative but not conservative group. Further prospective randomised, controlled trials with independent and blinded assessment with accurate CT and clinical evaluation will be required before ORIF can be adopted as the best practice.
