A specially designed compression plate has been used in symphysiodesis for chronic symphysiolysis with pelvic pain and discomfort suspected to be due to pelvic instability. Eight patients have been operated with this technique, and stable symphysiodesis was achieved in all. No signs of plate loosening were observed in any case.

A retrospective analysis of 65 symphysiotomies and 108 cesarean sections performed in 1988-94 after a failed trial of assisted delivery at the Port Moresby General Hospital (Papua New Guinea) revealed no significant differences in perinatal or maternal outcomes. There were no significant differences between groups in terms of duration of first and second-stage labor, Apgar scores, admission to a special care neonatal unit, or perinatal mortality. There were no maternal deaths. Mothers who had symphysiotomy required a longer hospital stay, but had fewer complications necessitating additional surgery (e.g., wound infection) than women delivered by cesarean section. These findings confirm that, with proper technique and selection of cases, symphysiotomy can both eliminate difficult vaginal deliveries and reduce maternal morbidity and mortality. Indications for this procedure include presentation of the vertex, moderate cephalopelvic disproportion, and a live fetus. The main complications are leg and pelvic pain, pelvic instability, and stress incontinence.

The human pelvis is susceptible to severe injury in vehicle side impacts owing to its close proximity to the intruding door and unnatural loading through the greater trochanter. Whereas fractures of the pelvic bones are diagnosed with routine radiographs (x-rays) and computerized tomography (CT scans), non-displaced damage to the soft tissues of pubic symphysis joints may go undetected. If present, trauma-induced joint laxity may cause pelvic instability, which has been associated with pelvic pain in non-traumatic cases. In this study, mechanical properties of cadaveric pubic symphysis joints from twelve normal and eight laterally impacted pelves were compared. Axial stiffness and creep responses of these isolated symphyses were measured in tension and compression (perpendicular to the joint). Bending stiffness was determined in four primary directions followed by a tension-to-failure test. Loading rate and direction correlated significantly (p<0.05) with stiffness and tensile strength of the unimpacted joints, more so than donor age or gender. The impacted joints had significantly lower stiffness in tension (p <0.04), compression (p<0.003), and posterior bending (p<0.03), and more creep under a compressive step load (p<0.008) than the unimpacted specimens. Tensile strength was reduced following impact, however, not significantly. We concluded that the symphysis joints from the impacted pelves had greater laxity, which may correlate with post-traumatic pelvic pain in some motor vehicle crash occupants.

We have retrospectively reviewed the clinical and radiological results in 204 consecutive adult patients who had surgical correction of 70 late post-traumatic pelvic nonunions and 134 malalignments. The deformed pelvises were subdivided into united (true), unstable, ununited, and partially stable malalignments with heterotopic bone. The principal complaints were of pain, pelvic instability, sitting imbalance, and apparent limb-length discrepancy. After surgery, 195 patients (96%) achieved a primary union and 144 (71%) had slight, intermittent or no pelvic pain, while pelvic instability was entirely eliminated. Overall, 131 patients (64.2%) were extremely satisfied, 58 (28.4%) were satisfied and 15 (7.4%) were unsatisfied. After reconstruction of the malaligned pelvises, 67 results (50%) were anatomical, 47 (35%) were satisfactory and 20 (15%) were unsatisfactory. For a pelvic nonunion with local osteopenia and malalignment, stabilisation of all three pelvic columns is recommended. True pelvic (united) malunions were the most satisfactorily realigned and had the fewest complications. Ununited and unstable malalignments, especially those with heterotopic bone, had the poorest corrections and the most neurological complications. A therapeutic alternative, by the local resection of a symptomatic bony prominence, and fixation in situ of a posterior pelvic nonunion, gives highly effective symptomatic relief with fewer complications. Despite this, many patients had persistent low back pain.

The article introduces the hypothesis that intramuscular connective tissue, in particular the fascial layer known as the perimysium, may be capable of active contraction and consequently influence passive muscle stiffness, especially in tonic muscles. Passive muscle stiffness is also referred to as passive elasticity, passive muscular compliance, passive extensibility, resting tension, or passive muscle tone. Evidence for the hypothesis is based on five indications: (1) tonic muscles contain more perimysium and are therefore stiffer than phasic muscles; (2) the specific collagen arrangement of the perimysium is designed to fit a load-bearing function; (3) morphological considerations as well as histological observations in our laboratory suggest that the perimysium is characterized by a high density of myofibroblasts, a class of fibroblasts with smooth muscle-like contractile kinetics; (4) in vitro contraction tests with fascia have demonstrated that fascia, due to the presence of myofibroblasts, is able to actively contract, and that the resulting contraction forces may be strong enough to influence musculoskeletal dynamics; (5) the pronounced increase of the perimysium in muscle immobilization and in the surgical treatment of distraction osteogenesis indicates that perimysial stiffness adapts to mechanical stimulation and hence influences passive muscle stiffness. In conclusion, the perimysium seems capable of response to mechanostimulation with a myofibroblast facilitated active tissue contraction, thereby adapting passive muscle stiffness to increased tensional demands, especially in tonic musculature. If verified, this new concept may lead to novel pharmaceutical or mechanical approaches to complement existing treatments of pathologies which are accompanied by an increase or decrease of passive muscle stiffness (e.g., muscle fibroses such as torticollis, peri-partum pelvic pain due to pelvic instability, and many others). Methods for testing this new concept are suggested, including histological examinations and specific in vitro contraction tests.

Overlapped pubic symphysis is a rare but serious pelvic injury. This study presents a case of overlapped dislocation of the pubic symphysis. He was managed by closed reduction under general anesthesia. The patient had urethral trans-section. At the latest follow up, seven months post injury; he was able to walk well without any pelvic pain. However, his urologic problems were continued. We also reviewed the literature and analyzed the data of the previous reports as well as the current case collectively. The two terms of "locked pubic symphysis" and "overlapped pubic symphysis" have been used synonymously in the literature. Overlapped pubic symphysis is commonly associated with fracture of the sacrum and urethral injury in the male patients. After closed or open reduction, if pelvic instability persists, it needs anterior and may posterior internal fixation to achieve a stable pelvis.
