Forty-three patients were randomly allocated to undergo either trapeziectomy alone (control) or with a ligament reconstruction and tendon interposition (LRTI) using an abductor pollicis longus tendon slip. The patients were reviewed at a median 13 (range, 7-29) months after surgery. The demographic characteristics, severity of disease and pre-operative clinical measurements of the two study groups were indistinguishable but LRTI lengthened the operation by approximately 15 minutes. Both groups expressed equal satisfaction with the operation and there were no significant differences between the two treatment groups. Simple trapeziectomy is an effective operation for osteoarthrosis at the base of the thumb and the addition of a ligament reconstruction was not shown to confer any additional benefit. A prospective randomized clinical study with a 2-year follow-up period was conducted.
                To analyze the effects of circumferential fusion using ALIF radiolucent carbon fiber cages and titanium posterior instrumentation on functional outcome, fusion rate, complications, and lumbar lordosis.
                Circumferential fusion has become a common procedure in lumbar spine fusion, both as a primary and salvage procedure. However, the claimed advantages of ALIF plus PLF over conventional PLF lack scientific documentation.
                From April 1996 through November 1999, a total of 148 patients with severe chronic low back pain were randomly selected for either posterolateral lumbar fusion with titanium CD-Horizon (posterolateral group) or circumferential fusion with a ALIF Brantigan cage plus posterior instrumentation. The Dallas Pain Questionnaire (DPQ), the Low Back Pain Rating Scale (LBPR), and a questionnaire concerning work status assessed their outcomes.
                Both groups showed highly significant improvement in all four categories of life quality (DPQ) as well as in the back pain and leg pain index (LBPR), as compared with preoperative status. There was a clear tendency toward better overall functional outcome for patients with the circumferential procedure ( < 0.08), and this patient group also showed significantly less leg pain at the 1-year follow-up evaluation ( < 0.03) and less peak back pain at 2 years ( < 0.04). Sagittal lordosis was restored and maintained in the circumferential group ( < 0.01). The circumferential fusion patients showed a higher posterolateral fusion rate (92%) than the posterolateral group (80%)( < 0.04). The repeat operation rate including implant removal was significantly lower in the circumferential group (7%) ( < 0.009) than in the posterolateral group (22%).
                Circumferential lumbar fusion restored lordosis, provided a higher union rate with significantly fewer repeat operations, showed a tendency toward better functional outcome, and resulted in less peak back pain and leg pain than instrumented posterolateral fusion. The clinical perspective of the current study implies a recommendation to favor circumferential fusion as a definitive surgical procedure in complex lumbar pathology involving major instability, flatback, and previous disc surgery in younger patients, as compared with posterolateral fusion with pedicle screws alone. Sixty-two ulnar nerves belonging to 44 patients with early neuritis were studied to assess the benefits offered by medial epicondylectomy and external decompression in addition to steroid therapy. The patients were randomly allocated to the surgical or the medical group. In those cases where there was bilateral involvement, surgery was carried out only on one side. All cases were assessed prior to treatment, and at predetermined intervals following treatment. This study presents the results after a 12-month follow-up. There was statistically significant improvement in both groups following treatment as assessed by improvement in motor and sensory functions and in the reduction of pain and tenderness. The study, however, failed to demonstrate any added benefit with surgical intervention as compared to steroid therapy alone in the treatment of early ulnar neuritis. Four treatment regimens for patients with specified combinations of low back pain and sciatica were evaluated. The largest group studied had low back pain with limited straight-leg raising (SLR) and in them the beneficial effect of manipulation in hastening pain relief was highly significant. In similar patients without limitation of SLR, the effect was of borderline significance. In all the other groups, treated patients also recovered more quickly than their controls. Traction, for patients with low back pain and sciatica, and epidural injections when a root palsy was present also produced some significant pain relief. The effect of sclerosants for back pain was less clear. Invasive treatment for abdominal pain due to chronic pancreatitis may be either surgical or endoscopic, particularly in cases of ductal obstruction. To date, the data published on the effectiveness of these two forms of therapy have been mostly retrospective, and there have been no randomized studies. A prospective, randomized study comparing surgery with endoscopy in patients with painful obstructive chronic pancreatitis was therefore conducted.
                Consecutive patients with pancreatic duct obstruction and pain were invited to participate in a randomized trial comparing endotherapy and surgery, the latter consisting of resection and drainage procedures, depending on the patient's individual situation. Patients who did not agree to participation and randomization were also further assessed using the same follow-up protocol.
                Of 140 eligible patients, only 72 agreed to be randomized. Surgery consisted of resection (80 %) and drainage (20 %) procedures, while endotherapy included sphincterotomy and stenting (52 %) and/or stone removal (23 %). In the entire group, the initial success rates were similar for both groups, but at the 5-year follow-up, complete absence of pain was more frequent after surgery (37 % vs. 14 %), with the rate of partial relief being similar (49 % vs. 51 %). In the randomized subgroup, results were similar (pain absence 34 % after surgery vs. 15 % after endotherapy, relief 52 % after surgery vs. 46 % after endotherapy). The increase in body weight was also greater by 20 - 25 % in the surgical group, while new-onset diabetes developed with similar frequency in both groups (34 - 43 %), again with no differences between the results for the whole group and the randomized subgroup.
                Surgery is superior to endotherapy for long-term pain reduction in patients with painful obstructive chronic pancreatitis. Better selection of patients for endotherapy may be helpful in order to maximize results. Due to its low degree of invasiveness, however, endotherapy can be offered as a first-line treatment, with surgery being performed in case of failure and/or recurrence. This prospective study compared the outcome--subjective, objective and radiographic--of two surgical techniques for treating basal joint arthritis of the thumb: a "simple" trapeziectomy (group I) and a ligament reconstruction/tendon (group II) interposition technique. There were respectively 22 patients in group I and 34 in group II, all women with primary osteoarthritis. Both techniques gave favourable results and there were no significant differences for pain relief, patient satisfaction, mobility, DASH-score, key pinch force and gripping force. However in group II, the trapezial height was better preserved indicating that the proximal migration of the thumb was prevented or limited. There was also a significant correlation between the remaining trapezial space and key pinch force. The study compared the efficacy of discectomy or arthroscopic lysis and lavage in patients with chronic closed lock of the temporomandibular joint (TMJ) in a prospective, randomized clinical trial.
                Twenty-two patients with a clinical diagnosis of chronic closed lock were prospectively randomized to either discectomy or arthroscopic lysis and lavage. The individual outcome in each patient was evaluated with a visual analog scale for pain and a questionnaire concerning mandibular functional impairment. The clinical evaluation included measurement of maximum interincisal opening and protrusion, recording of clicking and crepitation, and palpation for tenderness of the TMJ and jaw muscles. Recordings were made before the operation (baseline) and at the 1-year follow-up.
                Twenty patients completed the study. Discectomy and arthroscopic lysis and lavage significantly reduced pain and improved mandibular function. Discectomy reduced pain somewhat more effectively than arthroscopic lysis and lavage. The clinical recordings at the 1-year follow-up indicated similarly good outcomes after both procedures.
                Both discectomy and arthroscopic lysis and lavage are effective surgical methods for treatment of chronic closed lock of the TMJ. Considering that arthroscopic lysis and lavage is a minimally invasive outpatient procedure, it should be used as the first choice in surgical treatment of this condition.
                Copyright 2001 American Association of Oral and Maxillofacial Surgeons. Vertical banded gastroplasty (VBG) is a frequently used surgical procedure for the treatment of morbid obesity. It can be done open (OVBG) or laparoscopic (LVBG). The aim of this double-blind randomized clinical trial was to compare the postoperative outcome and 1-year follow-up of 2 cohorts of patients who underwent either OVBG or LVBG.
                30 patients with morbid obesity were randomized into 2 groups (14 OVBG and 16 LVBG). Pain intensity, analgesic requirements, respiratory function, and physical activity were blindly analyzed during the first 3 postoperative days. Complications, weight loss, and cosmetic results after 1 year follow-up were evaluated.
                Both groups were highly comparable before surgery. Surgical time was longer in the laparoscopic procedure. Patients in this group required less analgesics during the first postoperative day. There was an earlier recovery in the expiratory and inspiratory forces, as well as faster recovery of physical activities in patients who underwent LVBG. Postoperative complications were more frequent in the open group. Excess body weight loss after 1 year was similar in both groups. Cosmetic results were significantly better in the laparoscopic group.
                LVBG had advantages over the open procedure in terms of analgesic requirements, respiratory function, postoperative recovery, and cosmetic results. Fifty-seven ulnar nerves in 39 patients with early neuritis were studied to assess the benefits offered by medial epicondylectomy and external decompression in addition to steroid therapy. The patients were randomly allocated to the surgical or medical group. In those cases where there was bilateral involvement, surgery was carried out on only one side. All cases were assessed prior to treatment and after the first and second years following treatment. The improvement in motor and sensory functions attained at the end of the first year was sustained into the second year. The improvement sustained in both groups was similar even in the second year, and medial epicondylectomy with external decompression seems to have no added benefit as compared to steroid therapy alone in the early treatment of ulnar neuritis. Early diagnosis and treatment, especially in borderline lepromatous cases, seem to offer some hope of nerve function recovery.
Although it appears that no one procedure produces greater benefit in terms of pain and physical function, there was insufficient evidence to be conclusive. Trapeziectomy has fewer complications than trapeziectomy with LRTI.
