[Development of intramedullary nailing and the interlocking nail].

Development of practically feasible methods for intramedullary stabilisation of fragments is inseparably linked to the name of Gerhard Küntscher. The principle of elastic transverse fixation of the nail in the medullary cavity permits its use only in fractures in the median diaphyseal range of tubular bones. For multiple and comminuted fractures Küntscher recommended a so-called "detention" or "locking" nail. This was developed further by Klemm and Schellmann, thus extending the range of indication for intramedullary fragment stabilisation. The origins and phases of development of this method are shown.

External fixation as an alternative when treating 2nd and 3rd degree open lower leg fractures.

The infection rate of open lower leg fracture is extremely high. Surgical treatment guarantees a reduced risk of infection when compared with conservative treatments. But even osteosynthetic methods such as screw or compression plate fixation show unsatisfactory results because of the additional traumatization of the primarily injured soft tissue combined with a reduction of blood circulation. From July 1973 till September 1976 we treated 57 2nd and 3rd degree open shank fractures with osteosynthetic methods: 46 with compression plate osteosynthesis and 11 primarily or secondarily with external fixation. The osteitis-rate was 14%, in addition to that there was a soft-tissue infection rate of 5%. In order to change our therapeutical procedure we stabilized 2nd and 3rd degree open lower limb fractures and lower leg fractures complicated by soft-tissue damages consequently by external fixation. From October 1976 till May 1978 we treated 39 open shank fractures; 24 of them were 2nd and 3rd degree open fractures. They were treated by external fixation. This change in our surgical treatment resulted in an osteitis-rate of 2.6%, there was no case of soft-tissue inflammation. These results underline the superiority of treating 2nd and 3rd degree open lower leg fractures and fractures combined with soft-tissue injuries consequently and chiefly with AO external fixation.

Cerclage wiring in the management of comminuted fractures of the femoral shaft.

A retrospective series of 20 patients is presented, comprising 21 fractures of the femoral shaft treated by open reduction and internal fixation (usually by medullary nailing) combined with cerclage wiring. Most of the patients were young with comminuted fractures of the femoral shaft, many with multiple injuries. The aims of stable reduction and early sound union of the fracture in anatomical position were achieved in all cases and that of early mobilization of the knee to a good ultimate range of flexion in almost all cases.

Comparison of unreamed nailing and external fixation of tibial diastases--mechanical conditions during healing and biological outcome.

Locked intramedullary nailing and external fixation are alternatives for the stabilization of tibial shaft fractures. The goal of this study was to determine to what extent the mechanical conditions at the fracture site influence the healing process after unreamed tibial nailing compared to external fixation. A standardized tibial diastasis was stabilized with either a locked unreamed tibial nail or a monolateral fixator in a sheep model. Interfragmentary movements and ground reaction parameters were monitored in vivo throughout the healing period. After sacrifice, the tibiae were examined mechanically and histologically. Bending angles and axial torsion at the fracture site were larger in the nail group within the first five weeks post-operatively. Unlike the fixator group, the operated limb in the nail group did not return to full weight bearing during the treatment period. Mechanical and histomorphometrical observations showed significantly inferior bone healing in the nail group compared to the fixator group. In this study, unreamed nailing of a tibial diastasis did not provide rotational stability of the osteosynthesis and resulted in a significant delay in bone healing.

[Osteosynthesis of ipsilateral hip and femoral shaft fractures with the PFN-long].

AIM: The paper retrospectively evaluates a set of patients with ipsilateral fractures of the proximal femur and shaft treated with PFN-long. MATERIAL: 19 patients (14 males and 5 females), aged 48 in average, were treated from 1998-2003. The fractures included 2 types: combined intraarticular femoral neck and shaft fractures: 8 cases, and 11 cases of complex extraarticular proximal femoral fractures and its shaft. RESULTS: A total of 17 patients followed up for at least 12 months was evaluated according to the Sanders and Regazzoni scoring scale. Bone union resulted in all patients. This was accomplished within 6 months in 10 patients (59 %), 9 months in 16 patients (94 %), and one patient healed within 12 months. Excellent results were achieved in 59 %, good results in 35 % and a satisfactory result in 6 %. We have recorded 3 cases of postoperative complications (16 %). These complications were all due to imperfect reduction. Early complications included a wound haematoma with necessary operative revision. Late complications, such as delayed healing, were resolved by reoperation in 1 case. CONCLUSION: Long PFN is a quality implant which extends our options in the treatment of ipsilateral hip and femoral shaft fractures. It is one of the most beneficial implants in the category of reconstruction nails. The availability of only 3 nail lengths and 1 diameter presents a certain drawback.

Displaced tibial shaft fractures: a comparison of treatment methods.

Eighty-five overriding tibial shaft fractures (46 open, 39 closed) were treated at Ochsner Foundation Hospital between 1960 and 1972. Nine different treatment methods were employed by seven orthopedic surgeons. The best results were obtained in the nine patients treated by open reduction and either compression plating or external skeletal fixation with compresssion. All healed primarily in the briefest time and none had a complication.

Fracture treatment. The still unsolved problem.

The problem of the best method for fracture treatment is unsolved and awaits in genuity and intensive research. It is not known whether it is better to treat a fracture by rigid immobilization or by cyclical loading systems. Reports on the treatment of healing bones by the various contemporary methods are contradictory and inconclusive owing to the inherent lack of control in clinical studies. Selected experimental studies on the various biomechanical factors in fracture healing suggest that mechanical variables definitely alter qualitatively the healing of fractured bone. Although no studies have been specifically designed to show which mechanical factors resulted in the most efficient fracture healing, investigations suggest that healing under conditions of rigid fixation results in qualitative structural differences which constitute a weaker bone.

[Bundle wire nailing in pathological upper arm fractures].

Between 1973 and 1987 we applied stacked Bundle-nailing in 24 cases of pathological humerus fractures. It is a fast, low-risk technique with which a good stabilization can be obtained. Especially in patients with advanced malignant disease, a fast improvement of life-quality is significant.
