Hylan versus corticosteroid versus placebo for treatment of basal joint arthritis: a prospective, randomized, double-blinded clinical trial.

PURPOSE: Conservative, nonsurgical therapies for basal joint osteoarthritis, such as thumb spica splinting and intra-articular corticosteroid injections, remain the mainstays for symptomatic treatment. This study compares intra-articular hylan, corticosteroid, and placebo injections with regard to pain relief, strength, symptom improvement, and metrics of manual function in a randomized, controlled, double-blinded study. METHODS: Sixty patients with basal joint arthritis were randomized to receive 2 intra-articular hylan injections 1 week apart, 1 placebo injection followed by 1 corticosteroid injection 1 week later, or 2 placebo injections 1 week apart. Patients were evaluated at 2, 4, 12, and 26 weeks and assessed with Visual Analog Scale pain scores, strength measures, difference scores, Disabilities of the Arm, Shoulder, and Hand (DASH) scores, and range of motion measurements. RESULTS: All groups reported pain relief at 2 weeks. The steroid and placebo groups had significantly less pain at week 4 compared with baseline, but this effect disappeared by week 12. Only hylan injections continued to provide pain relief at 12 and 26 weeks compared with baseline. There were no significant differences in pain between groups at any time. At 12 and 26 weeks, the hylan group had improved grip strength compared with baseline, whereas the steroid and placebo groups were weaker. At 4 weeks, the steroid group reported in the difference score a greater improvement in symptoms (68%) compared with the hylan (44%) and placebo (50%) groups. Whereas at 26 weeks the hylan group reported the largest improvement in symptoms (68%), this was not statistically different from the placebo (47%) and steroid (58%) groups. There were no significant differences in Disabilities of the Arm, Shoulder, and Hand scores or range of motion among the groups. There were no complications from any injection. CONCLUSIONS: There were no statistically significant differences among hylan, steroid, and placebo injections for most of the outcome measures at any of the follow-up time points. However, based on the durable relief of pain, improved grip strength, and the long-term improvement in symptoms compared with preinjection values, hylan injections should be considered in the management of basal joint arthritis of the thumb. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic I.

Basicervical versus intertrochanteric fractures: an analysis of radiographic and functional outcomes.

This retrospective study compared the long-term stability and functional outcomes of basicervical versus intertrochanteric fractures, and evaluated the use of an additional derotational screw in the treatment of basicervical fractures. Sixty-six patients (28 with basicervical fractures and 38 treated for stable and unstable intertrochanteric fractures) were identified. All intertrochanteric fractures were treated with a sliding hip screw. Basicervical fractures were treated with a sliding hip screw with or without a derotational screw. Radiographically measured fracture collapse and tip-apex distance were measured at least 6 weeks after surgery; SF-36 score and Functional Recovery Score data was collected at least 1 year after surgery. The proportion of fractures with > 10% collapse was significantly greater in the basicervical group than the subset of stable intertrochanteric fractures (P = .009), but not than the subset of unstable intertrochanteric fractures. The mean SF-36 bodily pain section domain was greater (less pain) in the basicervical group than the unstable intertrochanteric group (P = .02). No other significant differences in SF-36 scores were noted between the basicervical and either intertrochanteric group. Basicervical fractures collapse more than stable intertrochanteric fractures, suggesting that they may have greater biomechanical instability. This instability, however, does not translate into clinically significant decreases in functional outcome. Using a derotational screw with a sliding hip screw does not affect fracture stability or clinical outcome.

Comparison of the volume of scoliosis surgery between spine and pediatric orthopaedic fellowship-trained surgeons in New York and California.

BACKGROUND: Controversy exists regarding the optimal fellowship training experience for surgeons who perform scoliosis surgery in pediatric patients. While many studies have demonstrated that higher surgical volumes are associated with superior outcomes, the volume of scoliosis procedures performed by pediatric orthopaedic-trained surgeons as opposed to spine surgery-trained surgeons has not been reported. METHODS: Validated, statewide hospital discharge databases from the states of New York and California were utilized to examine the volume of spinal fusion procedures performed for the treatment of scoliosis in patients who were eighteen years of age or less. Fellowship training of surgeons in New York who had performed more than fifty procedures from 1992 to 2001 (that is, more than five procedures per year) was determined, and the operative volumes of surgeons who had received pediatric orthopaedic as opposed to spine fellowship training were compared. Hospitals in California with either type of fellowship program were identified, and the operative volumes of hospitals and fellows with pediatric orthopaedic or spine fellowship training from 1995 to 1999 were compared. RESULTS: Among the 228 surgeons in New York who had performed one or more spinal fusion procedures in patients eighteen years of age or less from 1992 to 2001, only 13% (thirty) had performed more than five procedures per year. However, these thirty surgeons accounted for 75% (3858) of all 5136 procedures in this age-group. Surgeons who had completed a pediatric orthopaedic fellowship had performed a mean of 14.5 procedures per physician per year, whereas those who had completed a spine fellowship had performed a mean of 10.5 procedures per physician per year. Surgeons who had not completed either type of fellowship had performed a mean of 14.4 procedures per physician per year. In California, the mean annual volume of scoliosis procedures from 1995 to 1999 was 59.0 procedures per year at hospitals with pediatric orthopaedic fellowship programs and 15.7 procedures per year at those with spine surgery programs. The mean number of procedures per fellow at hospitals with pediatric orthopaedic fellowship programs was 31.6 procedures per fellow per year, and the mean number at hospitals with spine surgery programs was 12.7 procedures per fellow per year. Over time, there was a significant increase in the number of procedures per year at hospitals with both types of fellowship programs, but the percentage increase was greater for hospitals with pediatric orthopaedic fellowship programs than for hospitals with spine surgery fellowship programs (45.2% compared with 13.5%). CONCLUSIONS: These data indicate that, on the average, a large number of surgeons in New York performed five scoliosis procedures per year or fewer. Among higher-volume surgeons in New York, those with pediatric orthopaedic fellowship training performed more scoliosis procedures on children and adolescents than those with orthopaedic spine training did. In California, the volume of scoliosis procedures at hospitals with pediatric orthopaedic fellowship programs was nearly four times greater than that at hospitals with spine fellowship programs and the volume of procedures per fellow was more than two times greater, and this disparity is widening over time. These data are an important element in establishing what type of fellowship best prepares surgeons for scoliosis surgery.
