Opening wedge osteotomy for distal radius malunion: dorsal or palmar approach?
ABSTRACT Background There are various technical variations to consider when performing a corrective osteotomy of a distal radius malunion. We chose two of the more commonly reported techniques and compared the results of volar (palmar) osteotomy and fixation with dorsal osteotomy and fixation. Method Within a continuous cohort of patients who had undergone corrective osteotomy for a malunited Colles fracture, two groups could be identified retrospectively. In 8 patients a dorsal approach was used. A structural trapezoidal graft, subtending the amount of correction, was inserted into the osteotomy gap and stabilization was performed with a thin round-hole mini-fragment plate. In 14 patients a palmar approach and a palmar fixed-angle plate was used for correction of the malunion and for angular stable rigid fixation of the two fragments. The osteotomy gap was loosely filled with nonstructural cancellous bone chips. A retrospective comparison of the two groups was performed to see whether the outcome was affected by the use of either operative technique.The demographics, the preoperative amount of deformity, range of motion, pain, and force were comparable for both groups. All osteotomies healed without loss of correction. After a minimal follow-up of one year, radiographic appearance, objective functional parameters were assessed and subjective data (Disabilities of the Arm, Shoulder, and Hand [DASH] score and special pain and function questionnaire) obtained. Results These data did not show statistical difference for the two groups except for the amount of final wrist flexion. This parameter was significantly better in patients who had palmar approaches and fixed-angle plates. Conclusion Corrective osteotomies of distal radius malunions can be done in either way. It might result in some better flexion, if performed volarly.

ABSTRACT: A prospective radiological and functional assessment has been performed on 235 consecutively treated displaced Colles' fractures. The age and sex of the patients, as well as the initial displacement, involvement of articular surface and the adequacy of reduction of the fracture, were all analysed. Because of their greater potential for collapse, the better reduced fractures tended to lose more position during treatment. Despite this, in general, the better the reduction, the better was the final anatomical position of the fractures. The functional result at 3 months was related to the severity of initial displacement of the fracture and, to a lesser extent, to the anatomical result. Involvement of the radiocarpal and the distal radioulnar joints did not seem to affect adversely the patients' rehabilitation, but this was slower and less complete in the elderly. At 6 months, 60 per cent of patients had good or excellent function in the hand and wrist.Injury 04/1985; 16(5):289-95. · 2.46 Impact Factor

ABSTRACT: Patients with Colles' fractures have serious complications more frequently than is generally appreciated. A study of 565 fractures revealed 177 (31 per cent) with such complications as persistent neuropathies of the median, ulnar, or radial nerves (forty-five cases), radiocarpal or radio-ulnar arthrosis (thirty-seven cases), and malposition-malunion (thirty cases). Other complications included tendon ruptures (seven), unrecognized associated injuries (twelve), Volkmann's ischemia (four cases), finger stiffness (nine cases), and shoulder-hand syndrome (twenty cases). In many patients, incomplete restoration of radial length or secondary loss of the reduction position caused the complications.The Journal of Bone and Joint Surgery 02/1980; 62(4):613-9. · 4.31 Impact Factor

ABSTRACT: A corrective osteotomy for post-traumatic malalignment of the distal end of the radius was performed in twenty patients who were followed for an average of 3.6 years. The indications for correction were based on age, degree of deformity, limitation of function, pain, and appearance of the wrist. The procedure included an opening-wedge metaphyseal osteotomy combined with insertion of a graft and rigid internal fixation with a plate and screws to permit early motion. Depending on the direction of the angulation, a dorsal or volar approach was employed to guarantee a buttressing effect of the plate. The procedure gave satisfactory results when there were no degenerative changes in the radiocarpal or intercarpal joints and when the preoperative range of motion of the wrist was adequate. The results were graded as excellent in five patients, good in ten, fair in four, and poor in one.The Journal of Bone and Joint Surgery 11/1982; 64(8):1164-78. · 4.31 Impact Factor
