“…AVN was observed in 7% of each group. Preliminary results using a modification of the HB were presented by Joeckel et al [46]. In this technique, angular locking stability of four 2.5-mm K-wires is achieved within a polyetheretherketone (PEEK) plate, which is positioned at the lateral shaft cortex instead of the HB using an aiming device.…”

Proksimal humerus kırıkları özellikle yaşlı ve osteoporotik nüfusun hastalığı olmakla birlikte, yüksek enerjili travmalar sonrası genç nüfusta da oluşabilir. Özellikle son otuz yılda yapılan çalışmalar ile proksimal humerus kırıklarının evrelendirilmesi ve kırığın morfolojisinin ve vaskülaritesinin anlaşılması ile bu kırıkların prognozu hakkındaki önsezilerimiz güçlenmiştir. AO kırık prensipleri çerçevesinde kilitli anatomik plakların geliştirilmesi ile proksimal humerus kırıklarının tedavisinde kırığın kaynaması ve erken harekete başlanması açısından önemli bir yol katedilmiştir. Kırığın tipine göre tedavide konservatif yöntemlerin yanı sıra vida tespiti, sütür tespiti, gergi bandı, intramedüller çivi uygulaması, plak osteosentez ve artroplasti gibi pek çok cerrahi yaklaşım ve tespit tekniği uygulanmaktadır. Minimal invaziv cerrahi yaklaşımlar, minimal invaziv osteosentez ve kullanılan biyolojik tespit yötemleri ile tedavide, hem kırık hattındaki kanlanma bozulmadan hem de daha düşük morbidite ile yüksek oranda başarı sağlanmaktadır. Anahtar sözcükler: Kilitli plakla tespit; minimal invaziv cerrahi; proksimal humerus kırıkları.

“…It is generally accepted that overly rigid constructs can prevent callus formation and bone healing, while controlled micromovement at the fracture site can stimulate callus formation [4,5]. With semi-rigid implants like the Humerus-Block [6-9], Humerus-Block NG [10] and Button-Fix [11] (all DePuy Synthes, Solothurn, CH), an attempt was made to overcome over-stiffening of the fracture xation. Several studies have described the use of external xation as a semi-rigid, minimally invasive alternative for proximal humerus fracture xation using a variety of systems and surgical techniques [12][13][14][15].…”

INTRODUCTION : Proximal humerus fractures are usually treated with rigid angle-stable plates or nails. As an alternative, semi-rigid, minimally invasive systems have been developed for supportive fixation. A new system uses this principle with 2.5 mm partially threaded pins and external fixation. AIM: This study aimed to compare the fracture stability of the fixator with an angular stable plate about whether the mechanical stability is sufficient for early postoperative mobilisation. MATERIALS and METHODS: Human proximal humeri (paired, female, age ≥ 60, n = 8) were cut to a 3-part fracture and treated with an external fixator (Galaxy Shoulder, Orthofix) or an angular stable plate (Philos, DePuy Synthes). A physiological load was simulated based on a 45° abduction motion. The load level was continuously increased from 10 to 320 N within 10,000 cycles simulating the loads during rehabilitation. This was followed by another 10,000 cycles at 320 N for fatigue testing. Fracture motion was recorded with a 3D camera. Fracture stability was evaluated at a partial load of 160 N (simulating loads during early mobilisation). RESULTS: The fracture motion at the lateral aspect was significantly (p < 0.03) larger for the fixator compared to the plate both for axial and for shear movements, while at the medial aspects fracture motions were similar. Both fixation systems adequately stabilized the lateral tubercle fragment with no significant differences between fixation techniques. The migration of the fixator pins (1.1 ± 1.0 mm) and valgus rotation of the head fragment were minimal (3.1 ± 2.0°). The maximum load level of 320 N was reached by 7 plate constructs and 2 fixator constructs. CONCLUSION: Our results suggest that the external fixator system allows early but gentle postoperative mobilisation. More aggressive rehabilitation measures should be postponed after the healing of the fracture.
