Steroids are injected into joints for various indications. All steroid preparations relieve pain similarly over the long term. Therefore, decisions about which preparation to use are often arbitrary. We evaluated methylprednisolone acetate and a combination of betamethasone diproprionate and betamethasone sodium phosphate for short-term pain and the predictive value of short-term pain. Eighty-five patients were injected in prospective double-blind randomized fashion. Pain was evaluated by visual analog scale (1 = no pain, 10 = severe pain) at baseline, 3 days, and 3 weeks. No patient had joint pain immediately after injection. Three days after injection, mean (SD) pain levels were 5.1 (2.9) for methylprednisolone and 5.2 (2.6) for betamethasone (P = .97); 3 weeks after injection, they were 4.0 (2.8) and 3.7 (2.5), respectively (P = .57). Short-term pain increased from baseline for both preparations and decreased from 3 days to 3 weeks. Pain at 3 days and 3 weeks was positively correlated. This study does not support a difference in short-term pain between preparations. The significant correlation between short- and long-term pain may justify early decisions regarding treatment, especially in patients with high levels of initial pain.

BACKGROUND: The authors delineate a subgroup of proximal interphalangeal joint injuries with chronic pain and limitation of movement, despite a stable joint, and describe and evaluate a surgical procedure. METHODS: Through a volar approach, the volar plate is freed from scar but remains connected on either the ulnar or radial border. A new connection to the middle phalanx is established by creating a bony groove, and the volar plate is loosely attached distally. Fifty-four joints with chronic volar plate avulsion injuries of the proximal interphalangeal joint were evaluated. All patients had chronic pain and limitation of motion and function in a stable and congruent joint. Patients were examined at 6 weeks, 3 months, and 1 year after surgery. Range of motion, grip strength, and pain were evaluated. The average time to surgery was 10.5 +/- 11.8 months (range, 2 to 65.4 months). The mean postoperative follow-up period was 10.0 +/- 12.8 months (range, 3 to 73.5 months). RESULTS: All patients had an improved range of motion following surgery. The difference from the preoperative range of motion was statistically significant (p < 0.0001). None of the patients reported pain on rest after surgery, and five patients reported activity pain. The mean grip strength was 32.4 +/- 13.4 kg for hand that had been operated on and 41.0 +/- 14 kg for the hand that had not been operated on. CONCLUSIONS: This technique for repair of chronic volar plate avulsion injuries allows early motion and results in significant improvement in range of motion, pain, and overall function in this subgroup of patients.

Kienbock disease is diagnosed by imaging studies, and is often difficult to diagnose in its early stages. Our clinical impression is that wrist movement is more limited in Kienbock disease than when radial-sided wrist pain is caused by other conditions. The purpose of this study was to determine the use of wrist movement in differentiating between early Kienbock disease and radial-sided sprained wrist. We retrospectively reviewed 62 cases of Kienbock disease and 49 patients with radial-sided wrist sprain. Wrist movement at presentation was recorded. The two groups differed significantly in flexion and extension (p<0.001). The ability of movement of the affected wrist relative to the normal side to distinguish between the groups was excellent (AUC = 0.96, 0.97, respectively). The ability of wrist movement measurements to differentiate between early Kienbock disease and radial-sided wrist sprain emphasises that wrist movement should be measured prior to invasive or expensive testing.

Traditionally the scaphotrapezium-trapezoid joint is imaged through a posteroanterior view of the wrist. We describe an x-ray view that is aimed directly at the joint, which gives better visualization than the standard views.

The main indications for scaphotrapeziotrapezoid (STT) fusion are STT arthritis, rotary subluxation of the scaphoid, and Kienbock disease. The results of this procedure in the literature for each indication are discussed, as are the advantages, disadvantages,and alternative procedures. This article discusses the authors' surgical technique and results. The authors believe this procedure is a viable one in specific clinical scenarios.

PURPOSE: To assess long-term results and complications of cancellous bone graft taken from the distal radius. METHODS: A total of 1670 cases of bone graft taken from the distal radius for various indications were reviewed retrospectively. The patients were evaluated for success of bone grafting and for the following complications: fracture through donor site, local infection, DeQuervain's tenosynovitis, and neuroma of the superficial radial nerve. RESULTS: The overall complication rate including bone graft failure within a mean follow-up period of 4.5 years was 4%. Bone graft failure required regrafting with iliac bone in 38 patients (2.3%). DeQuervain's tenosynovitis was noted in 21 patients (1.3%), local soft-tissue infection was noted in 3 patients (0.2)%, fracture through donor site was noted in 2 patients (0.1%), and superficial radial nerve neuromas were noted in 2 patients (0.1%). There were no cases of osteomyelitis. CONCLUSIONS: Bone grafting from the distal radius is effective with minimal complications and is a practical adjunct to reconstructive hand procedures.

BACKGROUND: While an os trigonum at the posterolateral aspect of the talus is usually asymptomatic, this inconsistently present accessory bone has been associated with persistent posterior ankle pain, which has been described as the os trigonum syndrome. We present the clinical results of excision of the os trigonum through a posterolateral approach and report several factors affecting the clinical outcome. METHODS: During a five-year period from 1994 through 1999, forty-one patients had a failure of nonoperative treatment of os trigonum syndrome and underwent excision of a symptomatic os trigonum. In all cases, the os trigonum syndrome was diagnosed on the basis of the history, physical examination, and radiographs. Postoperatively, the patients were evaluated according to the American Orthopaedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot Scale. A questionnaire was used to evaluate the effect of several factors on the clinical outcome. RESULTS: The average duration of follow-up was forty-four months. The postoperative AOFAS score averaged 87.6 points. The thirty-three patients who had had symptoms for two years or less prior to the surgery had an average postoperative score of 90 points compared with 78 points for the eight patients who had had preoperative symptoms for more than two years (p = 0.011). Eight patients had sural nerve sensory loss, which was temporary in four and permanent in four. A superficial wound infection developed in one patient, and reflex sympathetic dystrophy developed in another. CONCLUSIONS: An os trigonum that is persistently symptomatic after a minimum three-month trial of nonoperative treatment can be excised through a posterolateral approach with highly satisfactory results. The main complication of this procedure is sural nerve injury.

PURPOSE: The purpose of this study was to review the results of 800 scaphotrapeziotrapezoid fusions performed over a 27-year period. METHODS: The patients were evaluated for postoperative range of motion, grip and pinch strength, pain, return to work, arthritis, and complications. RESULTS: The overall range of motion was 70% to 80% of the nonoperated side and strength was 69% to 89%. Of the patients 88% returned to previous employment. Arthritis developed in 1.8% of the patients. The overall complication rate was 13.4%. CONCLUSIONS: Scaphotrapeziotrapezoid fusion is a viable treatment option especially for a high-functional-demand young population with significant wrist pathology. Complications, specifically nonunion, can be minimized with careful technique.

We present a simple compression technique for treatment of difficult nonunions and joint fusions in the hand. This technique utilizes only K-wires and small vessel loops. The results of 44 consecutive cases were studied retrospectively. Union was achieved in 37/44 cases. The average time to union was 7 weeks and our results were comparable to those of other studies. We found this technique useful, especially in complicated cases.
