Early surgical treatment by anatomic repair gives the best results in the treatment of total and near-total ruptures of the pectoralis major muscle.
Our aim was to identify factors predisposing athletes to multiple stress fractures, with the emphasis on biomechanical factors. Our hypothesis was that certain anatomic factors of the ankle are associated with risk of multiple stress fractures of the lower extremities in athletes. Thirty-one athletes (19 men and 12 women) with at least three separate stress fractures each, and a control group of 15 athletes without fractures completed a questionnaire focusing on putative risk factors for stress fractures, such as nutrition, training history, and hormonal history in women. Bone mineral density was measured by dual-energy x-ray absorptiometry in the lumbar spine and proximal femur. Biomechanical features such as foot structure, pronation and supination of the ankle, dorsiflexion of the ankle, forefoot varus and valgus, leg-length inequality, range of hip rotation, simple and choice reaction times, and balance in standing were measured. There was an average of 3.7 (range, 3 to 6) fractures in each athlete, totaling 114 fractures. The fracture site was the tibia or fibula in 70% of the fractures in men and the foot and ankle in 50% of the fractures in women. Most of the patients were runners (61%); the mean weekly running mileage was 117 km. Biomechanical factors associated with multiple stress fractures were high longitudinal arch of the foot, leg-length inequality, and excessive forefoot varus. Nearly half of the female patients (40%) reported menstrual irregularities. Runners with high weekly training mileage were found to be at risk of recurrent stress fractures of the lower extremities.
Background: Hamstring injuries are common especially in athletes. Partial and complete tears of the proximal origin may cause pain and functional loss. Objective: To evaluate the results of surgical treatment for partial proximal hamstring tears. Methods: Between 1994 and 2005, 47 athletes (48 cases, 1 bilateral) with partial proximal hamstring tears were operated on. The cases were retrospectively analysed. Before surgery, 42 of the patients had undergone conservative treatment with unsatisfactory results, whereas in five patients the operation was performed within four weeks of the injury. Results: The mean length of the follow up was 36 months (range 6-72). The result of the operation was rated excellent in 33 cases, good in nine, fair in four, and poor in two. Forty one patients were able to return to their former level of sport after an average of five months (range 1-12). Conclusion: In most cases, excellent or good results can be expected after surgical repair of partial proximal hamstring tears even after conservative treatment has failed.
There are only a few epidemiological studies on the incidence of Achilles tendon (AT) ruptures. These show an increase in incidence in the West during the past few decades. The main reason is probably the increased popularity of recreational sports among middle-aged people. Ball games constitute the cause of over 60% of AT ruptures in many series. The 2 most frequently discussed pathophysiological theories involve chronic degeneration of the tendon and failure of the inhibitory mechanism of the musculotendinous unit. There are reports of AT ruptures related to the use of corticosteroids, either systemically or locally, but the role of corticosteroids in large patient series is marginal. In addition, recent studies do not confirm earlier findings of blood group O dominance in patients with AT rupture. Comparable series have been published with surgical versus nor surgical treatment and postoperative cast immobilisation versus early functional treatment. Although conservative treatment has its own supporters, surgical treatment seems to have been the method of choice in the late 1980s and the 1990s in athletes and young people and in cases of delayed ruptures. Early ruptures in non-athletes can also be treated conservatively. In small series of compliant, well motivated patients, functional postoperative treatment has been reported to be well tolerated, safe and effective. The lack of a universal, consistent protocol for subjective and objective evaluation of AT ruptures has prevented any direct comparison of the results. The results have been often assessed according to the criteria of Lindholm or Percy and Conochie, but no scoring is available for the analysis. We assessed a new scoring method and analysed the prognostic factors related to the results. There is also no single, uniformly accepted surgical technique. Although early ruptures have been treated successfully with simple end-to-end suture, many authors have combined simple tendon suture with plastic procedures of various types. No randomised study comparing simple suture technique and repair with augmentation could be found in the literature. The major complaint against surgical treatment has been the high rate of complications. Most are minor wound complications, which delay improvement but do not influence the final outcome. Major complications are rare, but often difficult to treat with minor procedures. For instance, large postoperative skin and soft tissue defects in the Achilles region can be treated successfully with a microvascular free flap reconstruction. The complications of conservative treatment include mostly reruptures and residual lengthening of the tendon, which may result in significant calf muscle weakness. It has been postulated that a physically inactive lifestyle leads to a decrease in tendon vascularisation, while maintenance of a continuous level of activity counteracts the structural changes within the musculotendinous unit induced by inactivity and aging. Proper warm-up and stretching are essential for preventing musculotendino...
We analyzed the complications after surgical treatment of Achilles tendon overuse injuries in 432 consecutive patients. The patients underwent a clinical examination 2 weeks, and 1, 2, and 5 months after the surgery. If a complication appeared, the patient was followed up clinically for at least 1 year. There were 46 (11%) complications in the 432 patients: 14 skin edge necroses, 11 superficial wound infections, 5 seroma formations, 5 hematomas, 5 fibrotic reactions or scar formations, 4 sural nerve irritations, 1 new partial rupture, and 1 deep vein thrombosis. Fourteen patients with a complication had reoperations: four patients for skin edge necrosis, two for superficial wound infection, two for seroma formation, one for hematoma formation, two for fibrotic reaction or scar formation, two for sural nerve irritation, and one for a new partial rupture. About every 10th patient treated surgically for chronic Achilles tendon overuse injury suffered from a postoperative complication that clearly delayed recovery. However, the majority of patients with a complication healed and returned to their preinjury levels of activity. To reduce this morbidity, it is essential that the surgeon be continuously aware of the possibility of postoperative complications and use proper surgical techniques.
