Pain free function of the thumb carpometacarpal (CMC) joint is essential for manual work. Osteoarthrithis of the thumb saddle joint is very common. Among different conservative and operative treatment options (ergotherapy, intraarticular infiltration, ligament reconstruction, resectionarthroplasty, arthrodesis, spacer), the implantation of a prosthesis is an alternative. This prospective study reports short time results of the uncemented hydroxilapatite coated Ivory prosthesis. The mean follow up time of the 21 patients was 12.1 months (range 6 to 18 months) and the mean age 57.2 years. The patients suffered from osteoarthritis of the thumb saddle joint stage II–III according to Eaton Littler. We evaluated the Disabilities of the Arm, Shoulder and Hand Score (DASH), pain with the visual analogue scale (VAS), clinical (abduction, flexion, strength) and radiological outcome.

The clinical results showed excellent pain relief with an improvement of the VAS from 7.3 preoperative to 0.8 postoperative (p< 0.05) and a decline of the DASH score from 42.9 to 6.05 points (p< 0.5). We measured an abduction with a mean of 47.5° and a flexion with a mean of 43.2°. The power of the fist grip was in mean 31.3 kg, of the key grip 6.4 kg. Radiological there were no signs of implant loosening. As complications occurred one posttraumatic trapezium fracture with luxation and one tendovaginits De Quervain.

The advantage of a total replacement of the CMC I joint, compared to the standard resection arthroplasty, is faster rehabilitation and preservation of the length of the thumb and so better strength. Our results are encouraging, but we have to wait for long time results mainly concerning implant loosening. In the case of the trapezium fracture with luxation we could remove the prosthesis and performed a resectionarthroplasty.

An unstable CMC I joint causes pain and dysfunction. Chronic subluxation can lead to cartilage damage and furthermore to rhizarthrosis. This study should evaluate the results of the Eaton Littler ligament reconstruction, in which a slip of the Flexor carpi radialis tendon (FCR) weaved through the basis of the first metacarpal and around the tendon of the Abductor pollicis longus and back to the FCR. Aftertreatment consists in 4 weeks cast, 4 weeks thermoplastic splint and physiotherapy, full opposition is allowed after 8 weeks.

We performed 10 operations in 8 patients with a mean age of 35.9 years (6 female, 2 male). In 8 times the diagnosis was a rhizarthrosis Eaton Littler stadium I and in 2 times a posttraumatic instability. The mean follow up time was 15.4 months. We evaluated subjective satisfaction with the Disabilities of the Arm, Shoulder and Hand Score (DASH), pain with the visual analogue scale (VAS) and the patients were asked, if they would undergo the operation again. Furthermore the range of motion (ROM) was examined, the strengths (key and pin grip) were measured and radiographs were made.

All patients would undergo the operation again. The mean DASH score was 17.4 points, the mean VAS in rest 0 and under stress 1.29. The mean pin grip strength was 3.98 kg and the mean key grip strength 7.14kg. The ROM was excellent with a mean anteposition of 39.5°, a mean abduction of 49.3°. The mean thumb opposition was Kapandji 9.9. Radiological there was no progression of the Eaton Littler stadium. As complications occurred 1 keloid and 1 hypaesthesia.

Our experiences with the Eaton Littler procedure for stabilisation of the hypermobile thumb saddle joint were positive. Long time results will show, if the procedure can prevent cartilage damage and progression of rhizarthrosis.

Introduction: Ulnocarpale Impaction Syndrom is defined as a degenerative disease on the basis of a relative mis-proportion in lenghth ratio between ulnar and radius, caused either by posttraumatic degeneration or idiopathic history. This causes an unusual high load bearing in the ulnar carpale joint as well as in the distal radio – ulnar joint. All these factors lead to a degeneration of the triangular discus, secondary lunotriqutral instability and chondromalazia of ulna, lunate bone and the triquetral bone.

Ulnocarpale Impaction Syndrom is diagnosed by clinical evaluation as well as typical radiologic findings. If non operative treatment leads to unsatisfactory results few operative options can be considered. Ulnar shortening osteotomy is one of them.

Material and Methods: From 2003 until 2006, 10 Patients were treated. 3 female patients and 7 male patients, with an average age of 46 years and/or 42,7 years were operated on. We evaluated forearm rotation, power, DASH Score, Numeral Analogue scale and radiologic findings considering ulnar lenghth and bone consolidation.

Results: Painfree forearm rotation increased significantly postoperatively. An increase in power was seen as well as a reduction of the DASH score of 51,6 points. Also the numeral analogue scale showed a reduction of 5 points. Postoperatively the ratio of ulnar to radial lenghth was nearly equal (average of ulnar -1mm) and all osteotomies showed normal bony healing.

Conclussion: Surgical therapy of painful ulnar impaction syndrom using ulnar shortening osteotomy seems to be a very feasible and practical procedure. In comparison to resection arthroplasty and the wafer procedure, ulnar shortening osteotomy shows no significant increase of pressure in the sigmoid fossa. Therefor it is the treatment of joice in our departement.

Bone marrow edema is a common cause of pain of the locomotor apparatus. We reviewed 50 patients (28 male, 22 female) with bone marrow edema of the knee. The patients mean age was 56.2 12.8 years. 8 cases were estimated to have an idiopathic BME, 10 posttraumatic and the other 32 ones to be secondary to an activated osteoarthritis or to mechanic stress. Iloprost is a vasoactive prostacyclin analogue. Therapy consisted of a series of five infusions with either 20 or 50g of iloprost given over 6 hours on 5 consecutive days each. Pain at rest as well as under stress were assessed with a semi quantitative scale from before and 4 months after therapy. MRI investigations were done before and repeated 4 months after therapy.

At the clinical follow-up 4 months after therapy, pain level at rest had diminished 84% (p < 0.0001). 70% of patients referred about a reduction, 30% about no change. Pain under stress decreased 57%, (p < 0.0001). 76% of patients showed lower pain under activity, 24% no change from baseline. There was no increase of pain level in any patient. In MRI in 85% a significant reduction of the BME size or complete restitution could be observed, 15% showed no change. Response rate to iloprost infusions came to 100% in idiopathic, 100% in posttraumatic and 66% in secondary BME. A significant reduction of side effects could be reached by lowering the daily dosage from 50 to 20g.

The authors conclude that parenteral application of iloprost might be a viable method in the treatment of BME of different origins.
