Purpose: To present the results of the tibial tuberosity osteotomy as part of the surgical approach for total knee replacement. Material and Methods: Tibial tuberosity osteotomy was performed during TKR for better exposure in 19 knees corresponding to 19m patients (9 male, 10 female), with average age 76 years (68–80). Four of the procedures were revisions. Fifteen were primary TKR, ten of which had been subjected to high tibial osteotomy previously. The rest þve patients had excessive valgus deformity (over 20 degrees), and they were approached through a lateral parapatelar incision. In two cases screws only were used to stabilize the osteotomised tubercle, and wire loops in the rest of them. Patients were instructed for partial weight bearing for six weeks postoperatively. Results: All osteotomies united in less than four months. In three cases (including the two with only screw þxation), proximal migration of the tuberosity was noted, but less than 2cm. No skin problems were encountered. Three patients,(22%), complained for anterior knee pain. Preoperative mean range of movement was 75 degrees, and improved to 90 degrees postoperatively. Average blood loss was 850 cc. Conclusions: The tibial tuberosity osteotomy offers excellent exposure in the revision and difþcult primary TKR, but it lengthens the operative time, and the blood loss is higher.

Purpose: To present the results of the use of shoulder prosthesis in multifragmented displaced humeral head fractures. Material-methods: 19 patients with comminuted and severely displaced fractures of the upper humeral epiphysis were treated with shoulder hemiar-throplasty. Their age varied from40 to 81 years (av:71). Seven patients had severely displaced four-part fracture; eight patients had four- part fracture-dislocation and four patients, three-part fracture dislocation with extended damage to humeral head articular surface. In 16 cases the arthroplasty was performed within 10 days, and in three, 6 weeks or more after the injury. The glenoid was not replaced in any of the cases. Results: The follow-up period was 16–84 months (av: 51). None of the patients had been reoperated, and none of the prosthesis was regarded ÒlooseÒ. The clinical assessment was done using the Constant-Murley scale. The score varied from 50 to 89 points, (av: 79). The average score for ÒpainÒ was 13(max 15) and for ÒmobilityÒ29(max 40). Average abduction reached 100 degrees and forward ßexion 110 degrees. At the last examination, 15 out of the 19 patients had returned to the previous social and occupational activities. Conclusions: The shoulder replacement offers satisfactory results in cases with comminuted and badly displaced fractures, but is a technically demanding procedure, and the time interval between injury and operation, strongly affects the result. Long lasting physiotherapy, patient compliance and cooperation are necessary for a satisfactory outcome.
