Isolated dorsal approach for the treatment of neglected volar metacarpophalangeal joint dislocations

Here, we present the clinical and radiological results of three neglected volar metacarpophalangeal dislocations in 2 patients, which were treated with open reductions 10 and 24 mo after the dislocations. There was a mean of a 20°(range 10°-30°) limitation of extension and a 53.3°(range 30°-70°) limitation of flexion preoperatively. Postoperatively, there was no limitation of extension(at 8 and 12 mo) in any of the fingers. In terms of flexion, one finger had full function, one had a 10° and the last one had a 30° limitation of flexion. Two of the fingers presented anesthesia preoperatively, which improved to hypesthesia postoperatively. One finger had hypesthesia, which improved postoperatively. During surgery, a ruptured dorsal capsule was found to have interposed into the joint, making closed reduction impossible. Our experience with these two patients demonstrated that, even in neglected cases, open reduction using an isolated dorsal approach may result in satisfactory clinical andradiological outcomes.     

Effects of joint mobilization on joint stiffness and active motion of the metacarpal-phalangeal joint

Joint mobilization is a common technique used to restore joint motion; however, documentation of its effectiveness is lacking. The purpose of this study was to determine if joint mobilization is effective in counteracting joint stiffness and decreased active range of motion of the metacarpal-phalangeal joint. It was hypothesized that there would be a significant increase in range of motion in those patients who received joint mobilization. Eighteen subjects who had been immobilized for the treatment of metacarpal fractures were randomly assigned to a treatment group that received joint mobilization or a control group that received no treatment. Measurements of active range of motion and torque range of motion prior to and after treatment/rest sessions were obtained for three sessions over a 1 week period. Analyses of variance were performed on the mean changes in excursion between groups and across sessions. The joint mobilization resulted in a significantly greater increase in excursion for subjects in the treatment group over subjects in the control group (p < 0.05). Joint mobilization does appear to be able to counteract the effects of immobilization and alter joint mechanics. J Orthop Sports Phys Ther 1992;16(1):30-36.     

Radioulnar joint fusion for distal radioulnar joint instability

Each one of this small group of patients illustrates a rare indication for the radioulnar joint fusion procedure in distal radioulnar joint instability. The case histories tell of a last ditch effort to salvage function in an extremity crippled by painful radioulnar instability after excision of the distal ulna. The fusions healed slowly and two required repeat surgery to achieve union. Today we would routinely add iliac bone graft to the fusion area to hasten healing. Rarely indicated, this is a salvage procedure that is done after failure of other procedures geared to preserve the rotation of the forearm. These patients all had successful salvage of their extremities for activities of daily living, but only one returned to his labor job. All were worker's compensation cases in physical jobs. Two patients had had prior radiocarpal fusions, making them even more restricted in function. This procedure should be kept in mind to be used in the rare cases of painful instability of the distal radioulnar joint when traditional motion-preserving procedures have failed.     

Relationship between joint laxity and radio-ulno-carpal joint morphology

The relationships between wrist laxity, ulnar variance, sigmoid notch inclination, and lunotriquetral motion were analysed in 60 normal volunteers. A strong correlation between ulnar length and sigmoid notch inclination was found for the entire group. Joint laxity was found to correlate with ulnar variance and lunotriquetral mobility in women, but not in men. The greater the laxity, the shorter the ulna and the greater the lunotriquetral motion during radial to ulnar deviation. These results support the concept that laxity increases the vulnerability of the wrist to injury.     

Endoprosthetic joint replacement of the contracted elbow joint

In a retrospective study 14 patients were reviewed 63 months after the implantation of a semi-constrained total elbow prosthesis in fourteen stiff or ankylosed elbows with a preoperative range of elbow motion of 30 degrees or less. The result, according to the Mayo Elbow Performance score, was excellent for four elbows, good for four, fair for one, and poor for five. The average arc of flexion improved from 7 to 68 degrees postoperatively with an average increase of 34 degrees in flexion, and 27 degrees in extension. There were seven complications affecting seven of the 14 elbows and four of these seven elbows underwent a revision procedure. Replacement for a stiff elbow is the least predictable, has the lowest overall rate of success and highest complication rate, than any other procedure. Nevertheless, these disadvantages must be placed in the context of alternative intervention options. The semiconstrained total elbow arthroplasty seems to be a useful option for patients older than 50 years with intrinsic stiffness involving more than 50% of the articular surface and with an ankylosed or very stiff elbow.     

Elbow joint

The elbow joint is a key joint for positioning of the hand. Four operations have to be considered for the rheumatoid elbow: removal of rheumatoid nodules and bursectomy, resection of the radial head, synovectomy, and arthroplasty. Synovectomy and arthroplasty are carefully analyzed, both from the point of view of recent international literature as well as personal experience. Synovectomy of the elbow is highly effective even when performed relatively late (stage 3 according to Larsen-Dahle-Eek) insofar as pain relief and swelling are concerned. In long-term disease, deterioration as assessed by radiology can usually not be prevented, but clinical improvement may be the reason for the relatively rare indication for arthroplasty. According to recent literature, the results of elbow arthroplasty vary greatly. Fully constrained hinges should no longer be used, and no decision has been made so far on whether semiconstrained or nonconstrained surface replacement is preferred. We use the semiconstrained GSB Mark II prosthesis, which has provided results in nearly 50 cases that rank among the best reported from the point of view of pain relief, improvement of ROM, and low complication rate. Use of our so-called transtricipital approach to the elbow has proved particularly valuable, especially with regard to lack of extension and muscle strength.     

Provocative sacroiliac joint maneuvers and sacroiliac joint block are unreliable for diagnosing sacroiliac joint pain

Mapping studies of pain elicited by injections into the sacroiliac joints (SIJs) suggest that sacroiliac joint syndrome (SIJS) may manifest as low back pain, sciatica, or trochanteric pain. Neither patient-reported symptoms nor provocative SIJ maneuvers are sensitive or specific for SIJS when SIJ block is used as the diagnostic gold standard. This has led to increasing diagnostic use of SIJ block, a procedure in which an anesthetic is injected into the joint under arthrographic guidance. However, several arguments cast doubt on the validity of SIJ block as a diagnostic gold standard. Thus, the effects of two consecutive blocks are identical in only 60% of cases, and the anesthetic diffuses out of the joint in 61% of cases, often coming into contact with the sheaths of the adjacent nerve trunks or roots, including the lumbosacral trunk (which may contribute to pain in the groin or thigh) and the L5 and S1 nerve roots. These data partly explain the limited specificity of SIJ block for the diagnosis of SIJS and the discordance between the pain elicited by the arthrography injection and the response to the block. The limitations of provocative maneuvers and SIJ blocks may stem in part from a contribution of extraarticular ligaments to the genesis of pain believed to originate within the SIJs. These ligaments include the expansion of the iliolumbar ligaments, the dorsal and ventral sacroiliac ligaments, the sacrospinous ligaments, and the sacrotuberous ligaments (sacroiliac joint lato-sensu). They play a role in locking or in allowing motion of the SIJs. Glucocorticoids may diffuse better than anesthetics within these ligaments. Furthermore, joint fusion may result in ligament unloading.
